What adjustments are made by the sympathetic division during exercise?

Answer:

its (A)

Explanation:

(a) Bends or β-turns are likely to occur at positions 4-7 (T-Y-G-P) and 18-21 (E-A-Q-P) in the provided amino acid sequence.

These regions tend to form turns because of the presence of glycine (G) residues, which have small side chains that allow for conformational flexibility and facilitate sharp turns in the protein structure.

The bent form of the amino acid sequence:

I - A - H - T

 Y - G - P

      F - G - A - A - M - C - K - W - E

               A - Q - P - D – G – M - E - C - A - F - H - R

(b) The amino acid glycine (G) is responsible for the bends in the protein structure. Glycine has a small side chain consisting of just a hydrogen atom, allowing for greater conformational flexibility and facilitating the formation of bends in the protein backbone.

(c) Potential intrachain disulfide cross-linkages can occur between cysteine residues (C) in the amino acid sequence. In this sequence, cysteine residues occur at positions 13 (C) and 23 (C). Therefore, a disulfide bridge can form between these two cysteine residues.

Blood doping rises the amount of hemoglobin in the bloodstream whereas Hemoglobin is an oxygen -carrying protein in the blood.

Blood doping is an illicit method of improving athletic performance by artificially boosting the blood's ability to bring more oxygen to muscles.

The three widely used types of blood doping are: blood transfusions. injections of erythropoietin (EPO) injections of synthetic oxygen carriers.

In blood doping, the athlete's own red blood cells are re-added to the bloodstream. This can be done by withdrawing one half to one litre of blood three to five weeks before a race. The withdrawn blood will be centrifuged, after which the red blood cells are collected and stored in a refrigerator.

Unsafe feeding positions, such as propping a bottle or placing the baby on a pillow, increase the risk for choking, overfeeding, and middle ear infections.

Feeding infants in an unsafe position, such as propping a bottle or placing the baby on a pillow, can increase the risk of a number of health problems. For example, propping a bottle can cause the baby to choke or overfeed, which can lead to excessive weight gain, digestive problems, and an increased risk of obesity later in life.

Additionally, placing the baby on a pillow can increase the risk of middle ear infections, which occur when fluid builds up in the space behind the eardrum and becomes infected. This is because feeding in a horizontal position can allow milk to flow back into the middle ear, creating an ideal environment for bacteria to grow.

True: The power of a nerve cell's reaction is independent of the stimulus's intensity, according to the all-or-none law, which one motor unit abides by.

The power of nerve cells or a muscle fiber's response is independent of the stimulus's intensity, according to the all-or-none law. If a stimulus is present over a set threshold, a neuron or muscle fiber will contract. The all-or-none law states that a single muscle fiber will either respond completely or not at all.

A motor unit is made up of a single neuron, also known as a nerve cell, that innervates (provides nerves to) a collection of skeletal muscles. The neuron stimulates all the muscle fibers in that specific motor unit to cause them to move when it gets information from the brain.

Answer:

Rats with ventromedial lesions should begin overeating; rats with lateral lesions should stop eating

Explanation:

The feeling of hunger stimulates a desire to eat.

The lateral hypothalamus is responsible for making an organism hunger and craves for food upon receiving any stimulation or signal that causes hunger.

A damaged to the lateral hypothalamus would mean the organism would not be able to sense hunger and thus, there would be no desire to eat. Hence, the rats with lateral lesions should stop eating.

On the other hand, the ventromedial hypothalamus is responsible for quenching hunger and signaling to the organism that it is full, hence, it would stop eating. However, when the ventromedial hypothalamus is damaged, the organism would not be able to tell when to stop eating. Hence, rats with ventromedial lesions should begin overeating.

For successful DNA replication, it is imperative that complementary bases pair up correctly. The importance of complementary base pairs lies in its ability to ensure the transfer of accurate genetic information with every cell division.

The process of DNA replication involves the critical requirement of complementary base pairing to ensure that the genetic information is accurately maintained during cell division. For this purpose, the two strands of DNA double helix undergo separation and act as templates for synthesizing new complementary strands.

The hydrogen bonding between Adenine-Thymine and Guanine-Cytosine allows the bases on each strand to pair accurately with their respective complementing base on the new molecule.

Essential in complementary base pairing is ensuring that the sequence of nucleotides on the new strand perfectly complements the original sequence on the template strand. By doing this, genetic information is transmitted from one generation of cells to another with precise accuracy, thus preventing errors or mutations.

The correct answer is Tectonic plate movement is a long-term environmental change.

Explanation:

When tectonic plates in the earth started to move, this process helped the planet to evolve and to shape the continents as exist today.

Different investigation teams have discovered that plates move approximately 2.5 centimeters per year. This movement is the key to the evolution of life and the development of the planet. This slow process involves mountain formation, rocks exposure, and chemical reactions that could stabilize the temperature on the earth´s surface for millions of years. And this stable weather is essential for the evolution of life. Plates movement carries carbon inside and outside of the planet, regulating the amount of carbon dioxide in the atmosphere (greenhouse effect). In this way, it can regulate the temperature. This regulation influence in precipitations,  chemical reactions that involve carbon release and minerals such as calcium, the water flow, volcanic eruptions, among other events. Plates tectonic is also responsible for life, as weathering and mineralization of the rocks release elements and nutrients that are necessary for the life of different organisms.    

So, up to this point, we can say that tectonic plates movement can not be prevented with planning, it does cause environmental change by regulating temperature, and hence it affects organisms.

There are short term effects and long term effects provoked by tectonic plates movement. Earthquakes are examples of short term effects, while mountain formation, ocean formation and, clime regulation are examples of long term changes.

Plates tectonic movement is a very slow process, that might last many years. The Andes formation, for example, started approximately 200 years ago, and these mountains are still rising. The subduction process has not finished as the plates are still moving.

Nerve impulses are transmitted only along exposed portions of an axon. The given statement is true this is due to the myelin sheath, which covers some axons and acts as an insulator.

The myelin sheath is made up of Schwann cells in the peripheral nervous system and oligodendrocytes in the central nervous system. These cells wrap around the axon, leaving gaps called nodes of Ranvier. It is at these nodes that the nerve impulses can be transmitted. The myelin sheath serves to increase the speed and efficiency of the nerve impulses by allowing them to jump from one node to the next in a process called saltatory conduction.

However, if the myelin sheath is damaged or degraded, nerve impulses may no longer be restricted to the nodes of Ranvier and can travel along the entire length of the axon, resulting in slower and less efficient transmission. So therefore the given statement nerve impulses are transmitted only along exposed portions of an axon is true this is due to the myelin sheath, which covers some axons and acts as an insulator.

Due to a large flood, sediment settles in a local river bed, making it more shallow on the river's bank. The most likely to occur in the river is c. Lower dissolved oxygen on the shallow banks

This is because a shallower river has less volume, which causes it to move more slowly. Slow-moving water is not capable of holding as much oxygen as fast-moving water. As a result, the water is warmer, which further decreases oxygen saturation. Oxygen is also depleted when the organic matter in the sediment is decomposed by bacteria. Oxygen-depleted water may be stressful or fatal to aquatic organisms that require it to survive.

Water temperature and dissolved oxygen are inversely related. When water temperature rises, the amount of dissolved oxygen decreases. Oxygen is removed from the water faster when temperatures are high. The reason for this is that water molecules, including dissolved oxygen, become less soluble as temperature rises. In summary, a large flood that causes sediment to settle in a river bed, resulting in a shallow river, is most likely to cause lower dissolved oxygen on the shallow banks. So therefore the correct answer is  is c) Lower dissolved oxygen on the shallow banks.
