Answer:

Lascaux (French: Grotte de Lascaux, "Lascaux Cave"; English: /læsˈkoʊ/,[1] French: [LASKO][2]) is the setting of a complex of caves near the village of Montignac, in the department of Dordogne in southwestern France. Over 600 parietal wall paintings COVER the interior walls and ceilings of the cave. The paintings represent primarily large animals, typical local and contemporary fauna that CORRESPOND with the fossil record of the Upper Paleolithic time. The drawings are the combined effort of many generations, and with continued debate, the age of the paintings is estimated at around 17,000 years (early Magdalenian).[3][4][5] Lascaux was inducted into the UNESCO World Heritage Sites list in 1979, as ELEMENT of the Prehistoric Sites and Decorated Caves of the Vézère Valley.[6]

Answer:

Rumen microbes ferment feed and produce volatile fatty acids, which is the cow's main energy source. Rumen microbes ALSO produce B vitamins, vitamin K and amino acids. In calves, the esophageal grooves allows milk to bypass the rumen and directly enter the abomasum.

The cecum plays an important ROLE in the digestive system by assisting in the FORMATION of feces. ... The ileocecal sphincter at the END of the small INTESTINE opens and closes to allow small amounts of chyme to enter the cecum at the beginning of the large intestine.

ANSWER:

Food is the main "source of energy" for all the LIVING things like plant, animals and humans. They all required food to carry out their daily life process and to live.

EXPLANATION:

     Plants are known as autotrophs it MEANS that they produce their food through the process of photosynthesis. Animals and humans are 'heterotrophs' because they can't produce their own food and they are dependent on other for the requirement of food.

    The food produced through the photosynthesis converted into glucose and then into STARCH which is used by the plant for various purposes for like growth.

     When humans and animals eat food, through the process of metabolism it is converted into energy and transferred into cell for their process. The cell takes this energy and uses it for SURVIVING and doing various ACTIVITIES.

It is based on EVOLUTIONARY ancestry and generates trees CALLED cladograms. Cladistics also identifies clades, which are groups of organisms that include an ancestor species and its DESCENDANTS. Classifying organisms on the basis of descent from a COMMON ancestor is called phylogenetic classification.

Answer:

Adenosine triphosphate (ATP), energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.

Cells require chemical energy for three general types of tasks: to drive metabolic reactions that would not occur automatically; to transport NEEDED SUBSTANCES across MEMBRANES; and to do mechanical work, such as moving muscles. ATP is not a storage molecule for chemical energy; that is the job of carbohydrates, such as glycogen, and fats. When energy is needed by the cell, it is CONVERTED from storage molecules into ATP. ATP then serves as a shuttle, delivering energy to PLACES within the cell where energy-consuming activities are taking place.

SOME FACTS ABOUT FISH:-

1.There are more than 20000 species of fish including groups of Jawless fish, bony fish and sharks with varying size, shape and colours.

2.Lifespan of average fish is 20 years. Wels catfish has longest life span of 60 years and weight is around 170 kg.

3.Fish prefer to be in groups known as shoal. A shoal can contain millions of fish.

4.The process in which group of fish are SWIMMING in the same direction is known as schooling.

5.Fishes form large number of groups and reproduce by releasing large quantities of eggs and sperm (FEMALES and males) in to the water and would ensure the fertilization of eggs.

6.There are few species LIKE sharks which develop their eggs internally and release the eggs only after the fertilization which would further gets hatched to the larvae.

7.Fish can LAY thousands of eggs at a time however very few would reach to maturity.

8.Fishes use different variety of noises for communication. They make very low pitch sounds and also use body parts like muscle vibration and bladder.

9.Fishes are mostly carnivorous, eating insects and other small fishes, only few of the species are herbivorous and their diet includes weeds and sea plants.

10.Fishes play a very important role in various cultures. They have the symbolic meaning in different religions and are worshiped as deities.

Modern ZOOS play a part in the conservation of endangered species by having - WORLDWIDE co-ordinated - breeding programs. They also usually offer more ENTERTAINMENT to their visitors than JUST seeing a bunch of animals. Modern zoos also try to house the animals in ways more suitable for the animals and try giving them a better life (by keeping the animals BUSY; giving them stuff to play with for example. Polar bears sometimes get given fish frozen in a lump of ice!).

Answer:

Molecular HOMOLOGY

Molecular HomologyThe DEEPEST level of homology: The MOLECULES that carry the instructions for making and running our bodies, encoded in our DNA. The evolutionary history of a species can be seen in its DNA sequences. The more closely related two species are, the more SIMILAR their DNA sequences.

Following are some examples of homology: The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or WHALE are homologous structures. They are different and have a different purpose, but they are similar and share common traits.

Answer:

cross pollintion develops new variety ,and the offsprings are healthier .

Explanation:

nature preders cross-pollination because of:-

(1*)UNISEXUALITY--flowers may be EITHER male or female and they may be born on seperate plant ,thus cross-pollination is tye only method.

(2*)DICHOGAMY--in MANY plants tge anthers and stigma matures at different times ...hence couldnot carry out self-pollintion.

(3*)SELF-STERILITY--this is a condition where even if the stigma recieves pollens from the anthers of the same flower, it fails to undergo further growthand PERISHES.

(4*)HERKOGAMY--(Mechanical or structural barriers)(herkos:barrier) in some flowers the pollens could not reach the stigma of the same flower.example: a hood covering the stigma acts as a machinical barrier in Pansy flowers .

(5*)HETEROSTYLY--in such flowers the syigma and antyers grows at different heights which does not favoures self-pollination.

An introduction to cells and cellular diversity

Updated Thursday 20th August 2015

What are cells and what do they consist of?

Image of a cell on a digital background.Copyrighted image Icon

Typical animal cell, displaying various internal organelles as well as the outer cell membrane

All cells are composed of the same kinds of molecular building blocks and share some common features. Despite these common features, cellular diversity is enormous, both between different types of organisms and within individual multicellular organisms (organisms that contain lots of different cell types – like human beings).

Some common properties of cells are that they use the same kinds of carbon based macromolecules as basic components such as proteins, lipids, carbohydrates and nucleic acids. They also use DNA as their genetic material, which they decode to make proteins. Finally, they are enclosed by a membrane and require a constant supply of energy. You might also be wondering whether another common property of cells is the ABILITY to grow and DIVIDE but note that within adult multicellular organisms some individual specialised cells have lost their ability to divide; for example, mature nerve cells (also known as neurons) are in fact unable to divide.

Animal and human cells have a number of specialised organelles (sub-cellular compartments) each enclosed by its own intracellular membrane. The DNA is separated from the cell cytoplasm because it is enclosed by a nuclear membrane, forming a LARGE organelle called the nucleus. Another kind of organelle found in these types of cells is mitochondria. Mitochondria play a vital role in cell function and survival because they generate most of the cell’s supply of a substance called Adenosine 5’-triphosphate (ATP). ATP moves around the cell and provides the energy that is needed to drive biochemical reactions that construct essential molecules from smaller units (for example, building a protein from amino acids).

The different types of cells in multicellular organisms are specialised to perform different functions, such as movement or secretion. Different molecules, particularly but not exclusively proteins, play an important role in these specialised functions. In animals and HUMANS the muscle cells synthesise specific proteins that enable them to contract, while non-contractile cells, such as skin cells, do not synthesise these proteins. The differential expression of proteins is therefore fundamental to the characteristic properties of specialised cells.

In addition to the differences in biochemical properties of the various cell types in multicellular organisms, the shapes of different cell types also vary. In humans, for example, red blood cells are small and disc shaped, whereas nerve cells (neurons) are have long processes, called axons, some of which EXTEND long distances, for example from the spinal cord to the muscles of the toes. The structure, or form (i.e. the shape and appearance) of cells is known as ‘cell morphology’ and plays an important role in cell function.

MATURE RBC in HUMAN..........

Answer:

There are a variety of controls that should be implemented in order to protect workers from exposure to smallpox. Workers that may be affected, either during regular work activities or during an EMERGENCY response, include, but are not limited to, emergency responders, healthcare workers, laboratory personnel, and others. The Smallpox Disease and Smallpox as a Bioweapon sections of this Safety and Health Topics Page provide extensive information on the hazards associated with smallpox and applicable controls. Additional guidance specific to various types of workers, and associated issues on recognizing and controlling exposure to smallpox is provided in the following sections.

What personal protective equipment (PPE) should emergency responders use when responding to a potential bio-attack involving smallpox? How should workers decontaminate themselves if they think they have been exposed to smallpox?

In a covert attack involving aerosolized smallpox, there would be no emergency response activity involving emergency responders. The first evidence that a potential attack had occurred would be diagnosis of the disease among exposed individuals, which would happen SEVERAL days after the actual release. However, it is possible that emergency responders would be required to respond to a bio-attack incident, such as notification regarding an aerosol dissemination device or other SUSPICIOUS release. The following references provide additional information regarding PPE, decontamination, and other precautions for emergency responders to consider during such an incident.

Interim Recommendations for the Selection and Use of Protective Clothing and Respirators Against Biological Agents. Centers for Disease Control and Prevention (CDC). Contains PPE guidance for emergency responders, including information on decontamination.

Healthcare Workers, Mortuary Workers, and Others

What personal protective equipment (PPE), infection control, and related precautions should healthcare workers use when treating patients with smallpox?

National infection control guidelines prescribe specific precautions to be taken when treating patients with KNOWN or suspected smallpox. These precautions include "Standard", "Droplet", "Airborne", and "Contact" Precautions, under certain circumstances. Patient ISOLATION and similar precautions may also be necessary. The following references provide detailed information regarding infection control procedures for smallpox.

OSHA Best Practices for Hospital-Based First Receivers of Victims. OSHA, (January 2005). Provides hospitals with practical information to assist them in developing and implementing emergency management plans that address the protection of hospital-based emergency department personnel during the receipt of contaminated victims from mass casualty incidents occurring at locations other than the hospital. Among other topics, it covers victim decontamination, PPE, employee training, and also includes several informational appendices.

Bioterrorism Readiness Plan: A Template for Healthcare Facilities. Association for Professionals in Infection Control and Epidemiology (APIC) and the Centers for Disease Control and Prevention (CDC), (April 13, 1999). Provides information on infection control, patient treatment, post-exposure management, decontamination, prophylaxis, and laboratory procedures. Specific information on smallpox is contained in Section II, pp. 23-26.

Henderson, Donald A. and Inglesby, Thomas V., et al. "Smallpox as a Biological Weapon: Medical and Public Health Management." Journal of the American Medical Association (JAMA) 281.22(June 9, 1999): 2281-2290. Considers the prospect of an aerosol release of variola virus, and provides information on epidemiology, infection signs and symptoms, diagnosis and monitoring, vaccination, medical treatment, infection control, environmental decontamination, and more.

Medical Management of Biological Casualties Handbook, Seventh Edition. U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID), (September 2011). Contains specific information on a number of potential bioterrorist agents.

What precautions are necessary when handling the bodies of patients who have died from smallpox?

Similar infection control precautions, as listed previously for live individuals, should be implemented for the post-mortem care of smallpox patients. These precautions apply to all workers performing post-mortem procedures on smallpox patients, including healthcare workers, morticians, forensic personnel, or others.
