Answer:

• Squamous Epithelium – These are thin, flat cells that are closely packed. The squamous epithelial cells line the cavities of the mouth, oesophagus, alveoli, and blood vessels. This tissue gives protection against mechanical injury and also blocks the entry of germs. If the squamous epithelium is ARRANGED in many layers, it is a compound squamous tissue CALLED the stratified squamous epithelium. We find these kinds of TISSUES in the skin and also the lining of the oesophagus.
• Cuboidal Epithelium – These cells are cuboidal in shape. They are found in the salivary glands, kidney tubules, sweat glands etc. Their main function includes absorption, secretion, and excretion. If the cuboidal epithelium is arranged in many layers it forms the stratified cuboidal epithelium. It is found on the inner side of the pancreatic ducts and salivary glands. They mainly help in protection.
• Columnar Epithelium – The columnar epithelium has cells that are pillar-like and column-like. We can find them in the lining of the stomach and intestine. Its functions include absorption and secretion.
• Ciliated Epithelium – When the columnar epithelial tissues have cilia, then they are ciliated epithelium. They are present in the lining of the trachea, kidney tubules etc. The RHYTHMIC movement of the cilia helps in the movement of material in one direction.
• Glandular Epithelium – These are modified columnar epithelial tissues. They are large cells that present in the TEAR glands, sweat glands etc. Their main function is secretion.

Answer:Evaporation is a SURFACE phenomenon so larger the surface area provides GREATER opportunity for the molecules to escape.

Hence the evaporation of a liquid increases with an increase in the surface area.

When tea is poured in a saucer, it cools faster.

The PARTICLES of tea on the surface absorb the HEAT of VAPORISATION from the remaining particles of the tea and evaporate.

The tea thus loses heat and cools faster.

Explanation:

Answer:

TORSION is a gastropod synapomorphy which occurs in all gastropods during LARVAL development. Torsion is the rotation of the visceral mass, mantle, and SHELL 180˚ with respect to the head and foot of the gastropod. This rotation brings the mantle cavity and the anus to an anterior position above the head.

In some groups of gastropods (Opisthobranchia) there is a degree of secondary detorsion or rotation towards the original position; this may be only partial detorsion or full detorsion.

The torsion or twisting of the visceral mass of larval gastropods is not the same thing as the SPIRAL coiling of the shell, which is also present in many SHELLED gastropods.

Answer:

Excretion is a process in which any living organism remove their METABOLIC waste from the body.

While OSMOREGULATION is the physiolosical process that an organism uses to mantain water balance.

In amoeba carbon dioxide and ammonia are the main waste material. These waste material are excreted by the process of diffusion through the body SURFACE. In amoeba contractile VACUOLE play some role in the REMOVAL of waste material.

b) to be PACKAGED into VIRIONS as new virus GENOMES. Like DNA VIRUSES, many RNA viruses have both "early" and "late"phases of gene expression, with regulatory proteins being synthesized early and structural proteins late. ... The entire viral RNA is then translated into a single "polyprotein" using the host cell ribosomes.

When an animal cell is kept in distilled

water, the solute concentration inside the cell is more than outside. Water will enter inside the cell due to osmosis. As a result the cell will swollen up and BECOMES TURGID. If the cell is placed inside water for longer period the cell may BURST due to excess water pressure.

ANSWER:

EVOLUTION is the process in which a new ORGANISM is EVOLVED from a pre EXISTING organism .

Its purpose is to reduce the bacterial population of a liquid such as milk and to DESTROY organisms that may cause SPOILAGE and human disease. ... MANY RELATIVELY heat-resistant (thermoduric) bacteria survive pasteurization, but these are unlikely to cause disease or cause REFRIGERATED milk to spoil.

Xylem is ONE of the TWO types of transport tissue in vascular plants, phloem being the other. The BASIC FUNCTION of xylem is to transport WATER from roots to stems and leaves, but it also transports nutrients.

Explanation:

i think chicken pox

Chickenpox is a highly contagious DISEASE caused by the varicella-zoster virus (VZV). The virus spreads easily from PEOPLE with chickenpox to others who have never had the disease or never been vaccinated. The virus spreads mainly through CLOSE contact with someone who has chickenpox.

To prevent spreading the infection, keep CHILDREN off nursery or school until all the spots have crusted over. Chickenpox is most infectious from one to two days before the rash starts, until all the blisters have crusted over (usually five to six days after the start of the rash)

Explanation:

The Human GENOME Project (HGP) was an international scientific research project with the goal of determining the sequence of nucleotide base pairs that make up human DNA, and of identifying and mapping all of the GENES of the human genome from both a physical and a functional standpoint.

IMPLICATIONS:

Common diseases like diabetes, heart disease, cancer, and the major mental illnesses are not inherited in simple ways. But studies comparing disease risk AMONG families show that heredity does influence who DEVELOPS these conditions. As a result, many doctors are careful to ask PATIENTS about their family histories of such illnesses.

Answer:

• A connective tissue is MADE up of three components: matrix, cells and fibres.

• The matrix is mainly a mixture of modified POLYSACCHARIDES and proteins, which are secreted by the component cells of the tissue.

• Different types of cells such as fibroblasts, mast cells, adipose cells etc. occur in the matrix.

• In all connective tissues EXCEPT blood, the cells secrete fibres made of collagen or elastin PROTEIN.

• These fibres provide strength, elasticity and flexibility to the tissue.

Trypanosomiasis, both of humans and of livestock, is one of the most IMPORTANT FACTORS restricting economic development in Africa today. The PRESENT paper outlines how this disease is limiting AGRICULTURAL, VETERINARY and forestry development in the Sudan, Bechuanaland and West Africa.

Alveoli and nephron serve as both STRUCTURAL and functional units in two distinct systems. Alveoli can be found in the lungs while nephron is found in the KIDNEY. The main difference between alveoli and nephron is that alveoli occur in the respiratory system whereas nephron occurs in the excretory system. The main function of alveoli is to provide sites for the gas exchange through the respiratory membrane in a process known as external respiration. Nephron serves as the basic filtration unit that produces urine from the BLOOD. The wall of both alveoli and nephron is one-cell thick and SURROUNDED by an extensive network of blood capillaries.

Some BABIES die in the uterus (womb) before they are born (called an intra-uterine fetal death). It can happen during the LAST HALF of pregnancy or, more RARELY, during the labour and birth, when it is known as intrapartum death. When the BABY who has died during labour and birth is born, this is called a stillbirth.

Answer:

The main FUNCTION of leucoplasts is storage.  Leucoplasts are plastids FOUND in plants where photosynthesis does not take place.

Being present in roots and tubers and VARIOUS other "non-photosynthetic" parts of the plants, they store substances like lipids, an array of proteins and carbohydrates in the form of 'starch'.

In addition to storage, the other function performed by leucoplasts is synthesis. It MAY be a synthesis of amino acids or various fatty acids or any other bio-product synthesis.

Answer:

VACUUM packing is a great WAY of keeping any TYPE of dry food safe from microorganisms.

Explanation:

In vaccum, the microorganisms do not get oxygen to RESPIRE, so they do not grow in the food that is vaccum packed. As a result, the food REMAINS protected.

So, nuts are kept fresh by vaccum packing.
