Answer :-

The characteristics of the "Large Intestine" are as follows :-

• The large intestine is MUCH shorter than the SMALL intestine but, it is comparatively wider than the small intestine.

• The large intestine of a human being is about 5 feet in LENGTH and is about 2.5 inches in width.

• The large intestine has three PARTS, namely- "Caecum", "Colon" and "Rectum".

• The caecum is very large and SPACIOUS in herbivores such as Rabbits, Horses and Donkeys.

• The large intestine serves to store unabsorbed food remainings for a short period of time.

• The large intestine does not secrete any enzymes.

• The large intestine absorbs nutrients and water from the food that comes from the small intestine.

Answer:

Explanation:

Mechanism of respiration- It occurs in following steps:

1. Breathing: Taking in oxygen and expelling carbon dioxide out is called breathing. It involves following steps :

Inhalation: It is taking in oxygen. It occurs DUE to contraction of muscles attached to ribs and flattened diaphragm which increase the volume of thoracic cavity. Hence, the PRESSURE inside the thoracic cavity decreases and air rushes into of the lungs.

Exhalation: It is expelling of carbon dioxideont. It occurs due to relaxation of muscles attached to ribs and diaphragm is dome shaped. This decreases the volume of thoracic cavity and decreases air pressure and EXPELS CO2 out of the lung.

2 Exchange of gases: It takes place between the alveoli of lungs and SURROUNDING blood capillaries.

.

3.Transport of gases in blood: Haemoglobin present in the blood transports O2 and CO2 in blood. Oxygen is transported from the lungs to the body cells in the form of any haemoglobin.

4.Oxidation of food: Breakdown of GLUCOSE molecules which produce energy. It occurs in mitochondria.

Explanation:

Algae (/ˈældʒi, ˈælɡi/; singular alga /ˈælɡə/) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping, including species from MULTIPLE distinct clades. Included organisms range from unicellular microalgae, such as Chlorella and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to 50 m in length. Most are aquatic and autotrophic and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem, which are found in land plants. The largest and most complex marine algae are called SEAWEEDS, while the most complex freshwater forms are the Charophyta, a division of GREEN algae which includes, for example, Spirogyra and stoneworts.

No definition of algae is generally accepted. One definition is that algae "have chlorophyll as their primary photosynthetic pigment and lack a sterile covering of cells around their reproductive cells".[2] Although cyanobacteria are often referred to as "blue-green algae", most authorities exclude all prokaryotes from the definition of algae.[3][4]

Algae constitute a polyphyletic group[3] since they do not include a common ancestor, and although their plastids seem to have a single origin, from cyanobacteria,[5] they were acquired in different ways. Green algae are examples of algae that have primary chloroplasts derived from endosymbiotic cyanobacteria. Diatoms and brown algae are examples of algae with SECONDARY chloroplasts derived from an endosymbiotic red alga.[6]

Algae exhibit a wide range of reproductive strategies, from simple asexual cell division to complex forms of sexual reproduction.[7]

Algae lack the various structures that characterize land plants, such as the phyllids (leaf-like structures) of bryophytes, rhizoids in nonvascular plants, and the roots, leaves, and other organs found in tracheophytes (vascular plants). Most are phototrophic, although some are mixotrophic, deriving energy both from photosynthesis and uptake of organic carbon either by osmotrophy, myzotrophy, or phagotrophy. Some unicellular species of green algae, many golden algae, euglenids, dinoflagellates, and other algae have become heterotrophs (also called colorless or apochlorotic algae), sometimes PARASITIC, relying entirely on external energy sources and have limited or no photosynthetic apparatus.[8][9][10] Some other heterotrophic organisms, such as the apicomplexans, are also derived from cells whose ancestors possessed plastids, but are not traditionally considered as algae. Algae have photosynthetic machinery ultimately derived from cyanobacteria that produce oxygen as a by-product of photosynthesis, unlike other photosynthetic bacteria such as purple and green sulfur bacteria. Fossilized filamentous algae from the Vindhya basin have been dated back to 1.6 to 1.7 billion years ago.[11]

In biology

The nucleus is an organelle found in eukaryotic cells. Inside its FULLY enclosed nuclear membrane, it contains the majority of the cell's genetic material. This material is organized as DNA molecules, along with a VARIETY of proteins, to form chromosomes.

In CHEMISTRY

the central and most important part of an OBJECT, movement, or group, forming the basis for its activity and growth.

In humans, the respiratory tract is the part of the anatomy of the respiratory system involved with the process of respiration. Air is breathed in through the NOSE or the mouth. In the nasal CAVITY, a layer of mucous membrane acts as a filter and traps pollutants and other harmful substances found in the air. Next, air moves into the pharynx, a passage that contains the INTERSECTION between the oesophagus and the larynx. The opening of the larynx has a special flap of cartilage, the epiglottis, that opens to allow air to pass through but closes to prevent food from moving into the airway.

From the larynx, air moves into the trachea and down to the intersection that branches to form the right and left primary (main) bronchi. Each of these bronchi branch into secondary (lobar) bronchi that branch into tertiary (segmental) bronchi that branch into smaller airways called bronchioles that EVENTUALLY connect with tiny specialized structures called alveoli that function in gas exchange.

The lungs which are located in the thoracic cavity, are PROTECTED from physical damage by the rib cage. At the base of the lungs is a sheet of skeletal muscle called the diaphragm. The diaphragm separates the lungs from the stomach and intestines. The diaphragm is also the main muscle of respiration involved in breathing, and is controlled by the sympathetic nervous system.

The lungs are encased in a serous membrane that folds in on itself to form the pleurae – a two-layered protective barrier. The inner visceral pleura covers the surface of the lungs, and the outer parietal pleura is attached to the inner surface of the thoracic cavity. The pleurae enclose a cavity called the pleural cavity that contains pleural fluid. This fluid is used to decrease the amount of friction that lungs experience during breathing..........
