The Lactose operon expresses as long as the Lactose is present. When all lactose is converted into glucose and galactose, the reaction stops..

iii) Cholera is caused by Vibrio choleraebacteria.

the energy available to the producer was 10percent

Food chain given : Grass -- Deer---Lion.Grass represent Producers. According to the 10%law, at each trophic level about 10% energy of the previous trophic level is passed to next level.

Energy available to Lion ---100JLet x be the energy available to Deer.10% of x =100Jso x =1000JSo deer has received 1000J of energy.Let Y be the energy available to GrassThen grass will receive 10%of Y=1000JY=10000JHence 10,000 joules of energy is available to producers

Any of various glands that discharge a fluid secretion and especially saliva into the mouth cavity and that in humans comprise large compound racemose glands including the parotid glands, the sublingual glands, and the submandibular glands.

Answer: d) LigaseExplanation:DNA ligase is an enzyme which facilitates the joining of DNA strands together for eg- a)during DNA replication, okazaki fragments are joined by this enzymeb)It also plays significant rule in making r- DNA , where it helps in glueing the desired gene with the plasmid

According to the 10% law, during the transfer of energy from organic food from one trophic level to the next, only about ten percent of the energy from organic matter is stored as flesh.Snakes = 5000 × (10/100) = 500J

Hawks = 500 × (10/100) = 50J

Energy available to the rats is 500J.Obeying the 10% law,Energy available to the snakes will be 10/100 * 500J = 50JEnergy available to the hawks will be 10/100 * 50J = 5J

1)In the digestion process, the saliva helps the teeth and tongue to masticate and mix up the food thoroughly. 2)Mucus in saliva helps in lubricating and adhering food particles into a bolus. Then the bolus conveyed to pharynx for further digestion. 3)Lysozyme present in saliva acts as an antibacterial agent that prevents infection.

Thesalivary glandsproducesaliva, which keeps the mouth and other parts of the digestive system moist. It also helps break down carbohydrates (withsalivaryamylase, formerly known as ptyalin) and lubricates the passage of food down from the oro-pharynx to the esophagus to the stomach.

Functions of salivary glands are:1. The salivary glands helps in mixing of food in the mouth during digestion.2. Salivary gland contains mucus which helps in lubricating food particles into bolus. 3. Salivary gland helps in partial digestion of carbohydrates.4. Saliva contains lysozyme which acts as an antibacterial agent that prevents infection.

the main function is to digest and moistorist the food

saliva will break the complex molecules of glucose to simplest form of glucose

saliva will break the complex molecules of glucose to simplest form of glucose

saliva break glucose to simplest form of glucose

functions of salivary gland or saliva :1.The salivery glands helps in mixing of food in mouth during ingestion.2.salivary gland contains mucus which helps in lubricating food particles into bolus.3.saliva contain enzymes that digest carbohydrate literally.4. saliva is antibacterial in nature that prevents infection.5.Saliva prevent corrosion of teeth during vomiting.

Main work of saliva is to make food lubricating and digest carbohydrates like starch70% in mouth

secret silivary juice in mouth and that's juice use carbohydrates digestion

1. Chemical digestion: breaks down starch by the function of “salivary amylase”2. Helps chewing and swallowing3. Lubricating effect: moisturizes the inside of the mouth and creates smoother speech4. Solvent effect: dissolves food and allows the tongue to taste foodCleaning effect: washes away food debris and bacteria remaining in the mouth5. Antibacterial effect: Lysozyme, peroxidase and lactoferrin fight against pathogenic microorganismspH buffering effect: Prevents sudden changes in pHSupplies minerals, including calcium and phosphorus, to teeth

there are three pairs of salivary glands which open in buccal cavity. parotids glands are present in front of the ear. the submandibular gland are present below the lower jaw the gland present below the tongue are called sublingual. salivary glands are made up of two types of cell. serous cell secrete a fluid containing digestive enzyme called salivary amylase. mucous cells produce mucus that lubricant food and helps swallowing

Salivary gland. The salivary glands produce saliva, which keeps themouthand other parts of thedigestive systemmoist. It also helps break downcarbohydrates(with salivary amylase, formerly known as ptyalin) and lubricates the passage of food down from the oro-pharynxto theesophagusto thestomach.

salivary glands secrete saliva which helps in making the food wet and can be swollen easily

The salivary glands produce saliva which the mouth and other parts of the digestive moist saliva is deeply associated with health or the functions of our body saliva has various functions including chemical digestion and cleaning of our mouth

The food chains are the living components of the biosphere. These are the vehicles of transfer of energy from one level to another. Through the food chains, transfer of materials and nutrients also takes place.

So a food chain is a picture of organisms in an ecological community that are linked to each other through the transfer of energy and nutrients, beginning with an autotrophic organism such as a plant and continuing with each organism being consumed by one higher in the chain. A food chain also shows how the organisms are related with each other by the food they eat.

We all depend upon food to survive. Energy is necessary for the biotic world to grow and sustain. A food chain describes the method in which a particular organism collects its food. It is an arrangement of who eats whom in a biological community or an ecosystem to obtain food. A food chain is a way of depicting the flow of energy from one organism to the next and to the next and so on. Everyone needs the energy transmitted through a food chain in order to survive.

Pepsin requires anacidic mediumwhile trypsin requires an alkalinemedium4. Theyactonly on one substrate i.e they are substrate specific. Eg Amylopsinactsonly on the starch in the duodenum 5. They speed up the chemical reactions without interfering in them.

Salivary Glands will help in secretion of saliva.So if ducts of salivary glands are closed then the following consequences may result:1. Absence of saliva in mouth and hence we cannot judge the taste of food.2. Carbohydrates cannot be digested which results in lack of energy .3. Because of lack of energy , metabolic activities will not take place.4. Body suffers wit disorders related to deficiency.5. Cell will lack all nutrients and ultimate the organism will die

The correct answer should be 200 J of energy.

Going by the hierarchy of the Trophic levels, the plants are primary producers, the herbivores are the primary consumers, and the carnivores are the secondary consumers.

So, according to the 10% law, at every trophic level, the energy is lost in the food due to biological processes like digestion, or energy lost during transfer or during the breakdown of respiration and other functions. Only 10% of the energy is stored in the flesh or in the body parts.

Therefore according to the 10% rule, if the plants have 20000 J of energy, then when it comes down to next trophic level of the herbivores, the energy level will come down to 2000 J. When it comes down to the nexttrophic level of the carnivores that includes Man, the energy available will be only 200 J.

-TheTen percent lawof transfer of energy from one trophic level to the next was introduced by Raymond Lindeman (1942).

- According to this law, during the transfer of energy from organic food from one trophic level to the next, only aboutten percentof the energy from organic matter is stored as flesh.

Describe the process of urine formation in the kidneys.

Bile increases the absorbtion of fat, and for II, chewing breaks down the food you eat into tiny molecules that combine with saliva secreted by the salivary glands in the mouth. Along with mucin and buffers, saliva contains the en-yme salivary amylase which acts on the starch in food and breaks it down to maltose.

enzyme*

The primary role of HCL is to sterilize the food you consume and prevent harmful bacteria from entering the gastrointestinal(GI) tract.

1.provide basic median and emulsifies fat.2 .convert carbohydrate to tu maltose and consist of ptylin help in softening of food for chewing

3.HCL help in killing bacteria which are get swallowed by food and provide basic mediam for working of pepsin

2 is the correct answer

option 4 is correct answer.

1 is the correct answee

In multicellular organisms like humans the body design is very complex and the oxygen demand is quite high. The oxygen requirements of an animal cannot be met by the process of diffusion as diffusion is a very slow process.To overcome this, multicellular organisms have specialized cells and tissues for performing various necessary functions of the body such as intake of oxygen and food. This helps for the higher animals like humans to meet the sufficient oxygen requirement. Unlike unicellular organisms, multicellular cells are not in direct contact with the outside environment. Therefore, diffusion simply cannot meet their oxygen requirements

The two reasons for appearance of variation among the progeny formed by sexual reproduction is mentioned below :-

1. The progeny formed due to sexual reproduction has characteristics from mother as well as father. Hence because of this the characteristics differ and result in variation.

2. The genetic material is exchanged between chromosomes before forming of zygote. Deoxyribonucleic acid (DNA) exchange in the chromosome. This results in forming of variation in the progeny.

Pancreatic enzymeshelp break down fats, proteins and carbohydrates. A normally functioningpancreassecretes about 8 cups ofpancreaticjuice into the duodenum, daily. This fluid containspancreatic enzymesto help with digestion and bicarbonate to neutralize stomach acid as it enters the small intestine.Allenzyme supplementscontain Pancreatin – a mixture ofpancreatic enzymeslipase, amylase and protease. These assist the digestion of fat, carbohydrates and proteins. On average patients need a minimum of between 200-250,000 units of lipase / day to avoid symptoms of mal absorption.

Since bile increases theabsorptionoffats, it is an important part of theabsorptionof thefat-soluble substances, such as thevitaminsA, D, E, and K. Besides its digestive function, bile serves also as the route ofexcretionfor bilirubin, a byproduct ofred blood cellsrecycled by theliver.

Amylasesare a group of hydrolases that degrade complex carbohydrates into fragments.Amylaseis produced by the exocrinepancreasand the salivary glands to aid in the digestion of starch. It is also produced by the small intestine mucosa, ovaries, placenta, liver, and fallopian tubes.

Reproduction is one of the important life process.When a living organisms (plant and animals)produces offsprings (young ones) is called as reproduction.

Appearence of variations among progeny because

- one gamete from male EX: sperm-one gamete from female EX:ovum-union of two different gametes (different DNA including chromosomes)-Which result in variations

not satisfied give another answer

Answer:b)BileExplanation:

Bileis a yellowish-green fluid that aids in the emulsification of fats. Bile is not an enzyme, but it does contain bile salts that emulsify large fat droplets.Thus it doesn't contain protein

b) bile is the correct answer

a) is the correct answer

a) pancreatic juice is the right answer

(b) bile juice is correct because bile juice secreted from the lever used for the emulsification of fats and it do not contain proteins

no it can but cross pollination only

ADP = Adinosine dipsosphateADPShort for adenosine diphosphate. An organic compound that is composed of adenosine and two phosphate groups. With the addition of another phosphate group, it is converted to ATP for the storage of energy during cell metabolism.

Digestionbegins in the mouth with chewing and ends in the small intestine. Asfoodpasses through the GI tract, it mixes with digestive juices, causing large molecules offoodto break down into smaller moleculesThe body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body. Waste products of digestion pass through the large intestine and out of the body as a solid matter called stool.

Table below shows the parts of the digestive process performed by each digestive organ, including movement of food, type of digestive juice used, and food particles broken down by that organ.

none of these.

Plasmolysis is the process in which cells lose water in a hypertonic solution. The reverse process, cytolysis, can occur if the cell is in a hypotonic solution resulting in a lower external osmotic pressure and a net flow of water into the cell.

Bile is produced in liver. The bile juice stored in sac called the gall bladder. It helps in the digestion of fats.

Bile or gall is a dark green to yellowish brown fluid, produced by theliverof most vertebrates, that aids the digestion of lipids in thesmall intestine. In humans, bile is produced continuously by theliver(liverbile), and stored and concentrated in thegallbladder
