Which of the following situations does diffusion not help, in our bodies?A. Oxygen entering the bloodstream.B. Food entering the
lubasha [3.4K]

Answer:

Glucose entering the intestines from the villus.This is by active transport.The latter is defined as the movement of molecules and  solutes from the region of lower concentration to the region of higher concentration against the concentration gradient.

Explanation:

All the above options depends on the diffusion gradients from one  higher region to another.e.g oxygen passing from high concentration from outside to lower concentration in blood stream,like wise Co2 from higher concentration from inside to outside,with passive diffusion lipids and water enter the small intestine(note amino acid and glucose,and fructose are different).

Active transport( through sodium dependent transporter) transports glucose to the intestine  from the villus.This is movements against concentration gradient because,glucose molecule are concentrated in intestine,and needed by the cells, in the body.Therefore they must be transported as a fast rate inn the blood .

However the absorption by the villi is very slow,therefore active transport is needed to move these against the concentration gradient into the intestine.And finally the blood.

If this were to be moved by  passive diffusion,the high concentration in the intestine will force this back into the villi

Therefore extra energy is needed by active transport for the glucose molecules to enter the intestine from the villus.

State five qualities of good draught animals. State four precautions to be observed when using draught animals
lesya692 [45]

Answer:

1. Conformation

Conformation refers to the form or shape of an animal. An animal with good conformation has a shape which shows the normal characteristics of its species and breed.

An animal used for draft must have a build well suited for pulling. It should be low to the ground, have powerful shoulders and legs, and have a broad frontal dimension that will accommodate the placement of a harness. It must be big enough to deliver, alone or in a pair, the power needed to pull equipment for an extended period of time. It must also be able to exert the concentrated or "instantaneous" effort needed to overcome temporary increases in the draft requirement caused by roots, rocks, hard soil, or inclines.

While some animals are bred to produce good draft abilities, within any breed individual animals vary greatly in these qualities, and care must be taken to choose those with the most potential. A thin but well-balanced animal can be strengthened with a good diet, health care, and work. However, an animal with a swayback, bad legs or impaired vision will be a constant source of trouble.

Selection is a process of matching ideal qualities against those seen or latent in a given animal. Good draft animals, regardless of species or breed, will have the following qualities:

• head well proportioned; squarish, sculptured look

• balanced vision and hearing; head carriage high and straight

• normal mouth; good teeth and jaw structure

• body should have depth and width; short, full neck, full shoulders, broad chest, and straight, broad beck

• wide, thick hindquarters, lowset and evenly-fleshed

• short legs, straight and square to the body; ample bone

• clean, well-developed joints; no swelling or unusual boniness; no turning in or out of knees or hoofs; free movement of limbs

• feet straight, hard; normal angulation of hoof.

Temperament

Temperament refers to the nature or disposition of an animal. Part of its temperament is determined genetically, both by breed and parentage; some of it is learned-a response to the treatment it receives from other animals or the people who raise and handle it.

Temperament is reflected in an animal's behavior, the way it moves and acts, and the way it reacts to the things around it. It is difficult to know much about temperament from the quick evaluation that usually precedes the purchase of a draft animal. The buyer must guess, from what is observable, whether or not an animal will accept new routines or maintenance and training, behave well in a pair, and prove to be a spirited yet steady-paced and manageable worker. Sometimes, what is observable is not typical of the animal's behavior. A basically lethargic bull, for example, may become very alert or nervous at the approach of a stranger, exhibiting a fierceness that could be misinterpreted as a strong yet controllable spirit. A donkey that is mishandled and mismanaged might kick or butt at its owner, or at any adult, but be led away quite easily by a child. The buyer must be aware of such possibilities and at the same time drew some basic conclusions about the animal's temperament.

The following are signs of good temperament:

• Good overall conformation and health. The animal has no physical handicaps that require it to compensate with aggressive or stubborn behavior. An animal with bad vision or hearing, an unsound leg or joint, or with a chronic respiratory or muscular weakness, protects itself by balking, spooking, shying, refusing to be harnessed or lying down during work. Its temperament is affected or shaped by its physical condition.

• The animal accepts the handling of the owner. The owner can pick up the animal's foot, open its mouth, lead it with a rope without having to use force or harsh measures.

• It does not shy or kick at other animals. The buyer should try to be present when it is being turned out with a herd or put into a corral with other animals. If an animal is unusually aggressive or cowardly, it may not work well in a pair. Aggressive animals force their work-mates to shy or lean out of the yoke or harness, while cowardly animals may refuse to step evenly with their mates, lagging behind.

When an animal is taken from its herd or original owner and staked out or corralled in a new place, it may experience shock. The animal may show signs of aggression, withdrawal, stubbornness, fear, or general anxiety. None of these reactions is unnatural during the adjustment period, and should not be taken as a sign of an unsuitable disposition. An animal's character becomes clear later, during training and preseason work. At that time the farmer can judge the ability of the animal to work as part of a pair or team. Buying an animal early in the offseason allows the owner time to seek a replacement should a problem arise.

Cellular respiration may occur by either aerobic or anaerobic means. Identify the type of respiration that matches each item. On
gulaghasi [49]

Answer:

The respiration, which takes place in the existence of oxygen is termed as aerobic respiration. In the process, glucose goes through the process of glycolysis to generate two molecules of pyruvate that further gets transformed into acetyl-CoA and enters the citric acid cycle. The energy generated from both the citric acid cycle and glycolysis is mediated by the energy carriers like FADH2, NADH2, etc to the ETC to produce ATP. The net production of ATPs while undergoing aerobic respiration is 36-38 ATPs.  

On the other hand, the respiration, which takes place in the non-existence of oxygen is termed as anaerobic respiration, also known as fermentation. The process takes place within the cells of yeasts, in the process also the formation of pyruvate takes place as the cell goes through the process of glycolysis. This pyruvate is further converted to acetaldehyde, which further gets converted to alcohol or ethanol. In the process, the net production of ATP is 2, and in animals, the same procedure is termed as lactic acid fermentation.  

Thus, glycolysis takes place both in aerobic and anaerobic respiration.  

The net gain of 36 or 38 ATPs takes place in aerobic respiration.  

The net gain of 2 ATPs takes place in anaerobic respiration.  

Lactic acid fermentation is a kind of anaerobic respiration.  

The alcohol fermentation is a kind of anaerobic respiration.  

The electron transport chain is used in the aerobic form of respiration.  

The citric acid cycle is also used in aerobic respiration.

The activation of receptor tyrosine kinases is characterized by _____.
xxTIMURxx [149]

Answer:

dimerization and phosphorylation

Explanation:

Protein kinase receptors are simply saying receptors with associated kinases (usually tyrosine kinases).

Protein kinases are enzymes that have the ability to modulate other enzymes (or some other proteins) by adding the phosphate group. This is known as phosphorilation process. As a result of structural change, protein can change its activity (phosphorilation usually increase the activity).

Such receptors are involved in a many processes within an organism that are important for the cellular growth, differentiation, metabolism .
