Adaptive social behaviours are animal behaviour they adapt in species community. It occurs among the same species, increases animals reproduction and is determined by natural selection.

The species of the organism exhibits a social adaptive behaviour among themselves to protect, reproduce, and survive. Aminals like insects, mammals and birds show adaptive social behaviours among their species.

This behaviour affects the reproduction of the species of the ecosystem and is subject to natural selection. An example of this behaviour is a group of ants together carrying food particles.

Therefore, option a. among species, c. determined by natural selection and d. increases reproductive chances are the characteristics of adaptive social behaviour.

The primary reason for tactilce meissner corpuscles's location close to the surface of the skin is because the cells need to be exposed to the external environment to be able to detect pressure and other forms of stimuli.

Tactile Meissner corpuscles are mechanoreceptors located near the surface of the skin. They are small and sensitive structures that allow the body to detect touch, pressure, and vibration. The Meissner corpuscles have a small and cylindrical shape that allows them to pick up any slight changes in pressure. They also have a dense network of nerve fibers that help them quickly and accurately relay information about touch sensations to the brain. Because of their relatively close proximity to the surface of the skin, the tactile Meissner corpuscles can sense very slight changes in pressure and help the body respond appropriately.

By changing a gene's instructions for making a protein, a variant(mutated protiens) can cause a protein to malfunction or to not be produced at all. When a variant alters a protein that plays a critical role in the body, it can disrupt normal development or cause a health condition.

In adrenocortical insufficiency, such as Addison's disease, the most severe manifestations are the result of an insufficient amount of circulating cortisol.

The adrenal cortex, which is responsible for producing cortisol, is not able to produce an adequate amount of this hormone in individuals with adrenal insufficiency. Cortisol plays a crucial role in regulating various physiological processes in the body, including metabolism, immune response, and stress response. A deficiency in cortisol can lead to severe symptoms such as fatigue, weakness, weight loss, low blood pressure, electrolyte imbalances, and impaired stress response. While other adrenocortical hormones may also be affected to some extent, the primary cause of the severe manifestations in adrenal insufficiency is the insufficient amount of circulating cortisol.

Proved that unpolished rice is responsible for beriberi:

One of the contributing factors to beriberi is the lack of vitamin B1 or thiamin. Asians consumed polished rice (without nutrient-rich bran or germ) during this time. Christiaan Eijkman, a Dutch physician, and pathologist discovered that feeding unpolished rice to chickens helped prevent beriberi.

In fermentation, the gas produced is usually carbon dioxide (CO2). Fermentation is a metabolic process that occurs in the absence of oxygen, and it involves the breakdown of glucose or other organic compounds to produce energy and other byproducts.

Different types of fermentation can produce different end products, such as ethanol, lactic acid, or acetic acid, in addition to CO2.

In cellular respiration, the gas used is oxygen (O2). Cellular respiration is a metabolic process that occurs in the presence of oxygen and involves the breakdown of glucose or other organic compounds to produce energy, CO2, and water (H2O). Cellular respiration is the primary process by which organisms convert food into energy that can be used to power cellular processes.

It is worth noting that while CO2 is a byproduct of both fermentation and cellular respiration, their main differences lie in the source of energy and the presence or absence of oxygen. Fermentation is a less efficient process than cellular respiration, as it produces less energy per molecule of glucose or other organic compound. Cellular respiration is the preferred method of energy production for most organisms, as it provides a more efficient and sustained source of energy.

The correct answer is C. The general adaptation syndrome refers to the body's response to stress, and consists of three stages: alarm, resistance, and exhaustion.

During the alarm stage, the body's immune system initially responds by increasing its functioning slightly. However, during the resistance stage, the immune system can become compromised as the body continues to adapt to the stressor. This can result in a slight decrease in immune system functioning during the resistance stage. Finally, during the exhaustion stage, the body's resources are depleted and immune system functioning can decrease more significantly. Therefore, the pattern of immune system functioning during each stage of the general adaptation syndrome is a slight increase during the alarm stage, a slight decrease during the resistance stage, and a more significant decrease during the exhaustion stage.

Numerous natural formations display the cardioid shape, which has biological relevance, which is determined by the equation r = 6 - 4cos().

The form of some animal hearts, including those of some cephalopods and sea gastropods, is one striking example. These species' cardioid-shaped hearts have developed to help them efficiently pump blood throughout their bodies. Their physiological demands are supported by the high blood flow that is maintained by the cardioid shape's narrowing apex. Additionally, certain flower species, such as several cyclamen species, have a cardioid-like arrangement of their petals. By offering an ideal landing site, its design helps to draw pollinators. The cardioid shape thus exhibits functional modifications for circulation and reproduction in biology.

The bones attach to each other and to muscles are done with the help of the Ligaments and Tendons- Connective Tissues.

There are two main connective tissues in our Musculoskeletal system which serve in joining the structures (bones and muscles) together and with each other.

Both muscles and bones work together to help the body move. The word "origin" refers to the fixed end of a bone whereas "insertion" refers to the moveable end. As a muscle contracts, it applies pressure to the tendon, which then transmits that pressure to the bone, pulling it in the direction of the action. Ligaments both maintain the integrity of the bones and limit their range of motion.

Glutamate is considered the major excitatory neurotransmitter.

Mechanism of action:

The neurons use neurotransmitters to interact with one other and their target tissues during the synaptic transmission process (neurotransmission). Nerve endings synthesise neurotransmitters, which are then released from them into the synaptic cleft. From there, receptor proteins in the cellular membrane of the target tissue bind to neurotransmitters. As a result, the target tissue is stimulated, blocked, or otherwise functionally altered.

More than 40 neurotransmitters found in the human neurological system, acetylcholine, norepinephrine, dopamine, gamma-aminobutyric acid (GABA), glutamate, serotonin, and histamine are some of the most significant.

Horses can be cremello (a light cream color), chestnut (a brownish color), or palomino (a golden color with white in the horse's tail and mane). Of these phenotypes, only palominos never breed true.

The reason palominos never breed true is because their distinctive coloring is caused by a single dominant gene that dilutes the chestnut color to a golden hue. When two palomino horses are bred, their offspring inherit one copy of the gene from each parent. If both copies are the palomino gene, then the offspring will also be palomino. However, if one parent passes on a chestnut gene instead of a palomino gene, then the offspring will be chestnut in color. If both parents pass on a chestnut gene, the offspring will also be chestnut. This means that there is a 50% chance that the offspring of two palominos will be chestnut rather than palomino. It is possible to selectively breed for palomino coloration by breeding horses that carry the palomino gene, but there is no guarantee that all offspring will be palomino. To increase the likelihood of producing palomino offspring, breeders often breed a palomino horse with a chestnut horse that carries the palomino gene. This increases the chance that at least one parent will pass on the palomino gene, resulting in palomino offspring. Despite this, there is still no guarantee that every offspring will be palomino, as the gene can be passed down in different combinations. Therefore, palominos are considered to be a bit more unpredictable in their breeding patterns compared to other horse phenotypes.
