The amino acid that is least likely to be found inside a transmembrane domain of a protein that spans the membrane 3 times is Asp (e).


A transmembrane domain is a protein region that extends across the cell membrane's lipid bilayer. Transmembrane domains are usually composed of hydrophobic amino acids that can interact with the lipid bilayer's hydrophobic tails.

Hydrophilic amino acids are unlikely to be present in transmembrane domains because they prefer to interact with water. Asp (aspartic acid) is the most hydrophilic amino acid due to its negatively charged side chain, which makes it polar and able to strongly interact with water.

In a protein spanning the membrane three times, Asp is least likely to be located in the transmembrane domains due to its hydrophilic nature. Therefore, Asp's high polarity and strong interaction with water make it less suitable for the hydrophobic environment of transmembrane domains in proteins spanning the membrane three times.

In summary, Asp is the most hydrophilic amino acid and is unlikely to be found in the transmembrane domains of proteins spanning the membrane three times due to its preference for interacting with water.

The other amino acids listed, Met (methionine), Asn (asparagine), Ser (serine), and Ala (alanine), are all less hydrophilic than Asp and are more likely to be found in transmembrane domains.

Therefore, the correct answer is Asp (e).

The correct match is d. secondary sex characteristic- the widening of hips in females. Primary  characteristics are the physical features that are present at birth and are directly related to the reproductive system. These include the presence of ovaries and testes, as well as the internal and external genitalia.

Secondary  characteristics, on the other hand, are the physical changes that occur during puberty but are not directly related to the reproductive system. These changes include the growth of body hair, changes in voice pitch, and the development of breasts in females and the growth of muscles in males.

Out of the given options, the only correct match is d. secondary  characteristic- the widening of  in females. This is because the widening of  in females is a typical secondary  characteristic that occurs during puberty and is not directly related to the reproductive system. The other options are incorrect because the development of breasts in females is a primary  characteristic, while the production of sperm in males is also a primary  characteristic.

Hypocalcemia is a condition in which there is a low level of calcium in the blood. Hypocalcemia is often caused by a deficiency of vitamin D, a lack of dietary calcium, or an underlying medical condition that affects the body's ability to absorb or regulate calcium. This disorder may have a number of clinical signs and symptoms, including the Trousseau sign, Chvostek's sign, tetany, carpopedal spasm, seizures, and laryngospasm .Positive Trousseau's and Chvostek's signs are both neurological

symptoms that occur when there is a low level of calcium in the blood. Trousseau's sign is characterized by the induction of carpal spasm when a blood pressure cuff is inflated above systolic blood pressure for three minutes. A positive Chvostek's sign is shown by the contraction of the facial muscles on one side of the face when the facial nerve is tapped over the zygomatic bone.

Lymphatic tissues of the lymphatic systems consists of unencapsulated aggregates of lymphocytes within organs of the body.

In vertebrates, the lymphatic system, also known as the lymphoid system, is an organ system that works in conjunction with the circulatory system and is a component of the immune system. A vast network of lymphatic veins, lymph nodes, lymphatic or lymphoid organs, and lymphoid tissues make up this structure.

False. Humans have been shown to produce pheromones, although their effects on behavior and physiology are still being studied. Pheromones are chemical signals that are released by animals, including humans, to communicate with others of the same species.

While the existence and function of human pheromones is still debated, there is evidence that they can influence social and sexual behavior. For example, studies have found that women can synchronize their menstrual cycles through exposure to pheromones, and that men may be attracted to women who are ovulating based on the presence of certain pheromones. Additionally, some pheromones have been shown to have a calming effect on humans, while others may elicit a fear response. Overall, while the study of human pheromones is still in its early stages, it is clear that they do exist and can play a role in human behavior and communication.

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.
