Answers
Answer:
Dehydration Synthesis
The monomers combine with each other via covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts.
Amino acids can undergo dehydration synthesis reaction to form larger molecules called as Polymers.
What is dehydration synthesis?Dehydration synthesis is a sort of chemical process in which, after the loss of water, two smaller molecules are combined to create a larger molecule. Condensation or dehydration reactions are other names for dehydration synthesis. Water is produced during dehydration synthesis as one of the principal byproducts of the reaction. When the proton (H) of one molecule bonds with the hydroxyl group (OH) of another molecule, water is created. A new covalent bond is created between the two molecules to produce a bigger complex when water is produced during the reaction and then evaporates.To know more about the dehydration synthesis, refer :

When humans breed organisms, they are selecting variations that occur naturally in populations.
True or false ?
Answers
Answer:
TRUE!!!
Explanation:
Artificial selection, often known as "selective breeding," is when people choose animals or agricultural products based on desirable features, hence it is a true statement.
What is Artificial selection?Different phenotypes can be introduced into an organism via genetic changes that change gene activity or protein function.
Natural selection is the process of identifying advantageous traits in plants and animals and taking actions to improve and perpetuate those traits in subsequent generations.
If a trait is advantageous and aids an individual in surviving and reproducing, the genetic variation is more likely to be passed to the next generation.
Therefore as opposed to letting the species evolve naturally without human intervention, as in the natural selection, hence it is a true statement.

How would you characterize wallaces idea that "the life of animals is a struggle for existence"
Answers
Wallace's idea that "the life of animals is a struggle for existence" can be characterized as the concept that animals face competition and challenges in their environment, and those individuals with advantageous traits have a better chance of surviving and reproducing.
Wallace's idea aligns with the principle of natural selection, which states that organisms with favorable traits are more likely to survive and pass on those traits to future generations. According to Wallace, animals constantly face challenges in their environment, such as finding food, avoiding predators, and securing mates. These challenges create a competitive environment where individuals must strive to succeed and reproduce.
In the struggle for existence, animals must adapt to their surroundings, develop advantageous characteristics, and compete for limited resources. The individuals that possess traits that enhance their survival and reproductive success have a higher chance of passing on those traits to their offspring. Over time, this can lead to the evolution of new species or the refinement of existing traits.
Wallace's idea highlights the dynamic and competitive nature of the natural world, where individuals must constantly adapt and compete to ensure their survival and the continuation of their species. It emphasizes the role of competition and adaptation in shaping the diversity and complexity of life on Earth.

why do you think so many russians classify themselves as nonreligious?

the main function of bile salts is to a. stimulate the absorption of minerals through the intestinal wall. b. emulsify lipids in the digestive tract. c. serve as hormonal agents in the digestive process. d. provide a pathway for lowering cholesterol levels.
Answers
The main function of bile salts is to emulsify lipids in the digestive tract. Bile salts are produced by the liver and stored in the gallbladder until they are released into the small intestine.
When fat enters the small intestine, bile salts are released and they surround the fat droplets, breaking them down into smaller particles that can be more easily digested by enzymes. This process is called emulsification, and it increases the surface area of the fat, allowing enzymes to access it more easily.
Without bile salts, digestion and absorption of fats would be much less efficient. Therefore, the emulsification of lipids is the main function of bile salts.

Which features demonstrates cold adaptation among neandertals?
Answers
Neanderthals demonstrated several features that indicate cold adaptation, including robust body structure, large nasal cavities, and specialized cranial features.
Neanderthals, an extinct species of humans, inhabited regions with cold climates during the Pleistocene era. Their physical features indicate adaptations to survive in such environments. Firstly, Neanderthals had a robust body structure with stocky builds and shorter limbs, which helped them retain body heat in colder conditions. This body shape reduced the surface area-to-volume ratio, minimizing heat loss.
Secondly, Neanderthals had large nasal cavities, which are believed to have been advantageous in cold environments. The increased nasal volume allowed for the warming and humidification of cold, dry air before it reached the lungs, reducing the risk of respiratory issues caused by inhaling cold air.
Lastly, Neanderthals possessed specialized cranial features, such as a prominent brow ridge and a low, elongated skull. These features may have helped protect their faces and brains from the harsh elements, including cold temperatures and physical stress.
Together, these adaptations suggest that Neanderthals were well-suited to survive in cold climates by minimizing heat loss, protecting their respiratory systems, and providing physical protection. These cold adaptations were likely beneficial for their survival in the challenging environments they inhabited during their existence.

what signals that act within the animal body are produced by endocrine glands?
Answers
The signals that act within the animal body and are produced by endocrine glands are known as hormones.
Endocrine glands are responsible for the production and secretion of hormones, which act as signals within the animal body. These hormones are released into the bloodstream and carried to target tissues or organs, where they bind to specific receptors and trigger a response.
Some of the major endocrine glands in animals include the pituitary gland, thyroid gland, adrenal gland, pancreas, and gonads. Each of these glands produces a specific set of hormones that regulate various physiological processes, such as growth, metabolism, stress response, and reproduction.
For example, the pituitary gland produces hormones such as growth hormone, which stimulates the growth and development of tissues and organs, and luteinizing hormone, which regulates the production of sex hormones in the gonads. The thyroid gland produces hormones such as thyroxine, which regulates metabolism and body temperature. The adrenal gland produces hormones such as cortisol, which helps the body respond to stress.
In addition to these major endocrine glands, there are also smaller endocrine glands scattered throughout the body, such as the pineal gland and thymus gland. Each of these glands produces hormones that help regulate specific processes within the body.
Overall, the signals produced by endocrine glands play a crucial role in maintaining homeostasis and regulating various physiological processes in animals.
