A hormone is the type of signal best suited for this task whenever a given signal needs to be sent to many different cells at many different locations throughout a multicellular organism.
By attaching to receptors on target cells, hormones differs cellular functions. A target cell's number of receptors may rise or fall in response to hormone action. Through intracellular or plasma membrane hormone receptors, hormones can directly or indirectly impact cells. A receptor can respond when a hormone or many hormones are present, which starts a cascade of signaling.
The hormone receptor interacts with several molecules to cause a range of changes, including an up-or down-regulation of nutrition sources, growth, and other metabolic processes. The steroid hormones activate cell signaling pathways that control certain genes in the DNA of the cell. By boosting or lowering the production of mRNA molecules, the hormone and receptor complex function as transcription regulators.

you are leading a team of researchers at a pharmaceutical company. your goal is to design drugs that help fight cancer. specifically, you want to focus on drugs that bind to and inactivate certain proteins, thereby halting cell cycle progression. one of your team members suggests targeting the retinoblastoma (rb) protein and inhibiting this protein. will this approach be successful? why or why not?
To design drugs that help fight cancer, targeting the retinoblastoma (rb) protein and inhibiting this protein will not be successful.
What will happen when you target the retinoblastoma (rb) protein ?Targeting the retinoblastoma (rb) protein and inhibiting this protein during the research for designing drugs for cancer will not be a successful approach.
Rb is a tumor-suppressor protein and it functions to inhibit the action of a number of cell cycle regulatory proteins. A drug designed to inactivate the Rb protein would create the same situation as in a cell that lacks both copies of the Rb gene.
Lack of Rb activity releases the inhibition of cell cycle regulatory proteins and thereby promoting cell cycle progression rather than halting it.

How can children from the same parents look so different?
The answer has to do with the fact that each parent actually has two different sets of genes. And that each parent passes only half of their genes to their child. And that the half that gets passed down is random. All of this together ensures that each child ends up with a different, unique set of genes
Explanation:
Hope this helps everyone even you :)
Answer: Each parent has two different sets of genes, which means that each parent only passes half of their genes to their child. The half that gets passed down is random so each child ends up with a different, unique set of genes. This can cause children from the same parents to look so different.

Hi can you help me come up with a hypothesis for a plan and design lab?
the problem statement was that Mary uses an enzyme based detergent for washing and noticed that it cleaned her clothes better in warm water rather than cold water.
Provide a hypothesis to the problem statment.
Answer:
The enzymes in the detergent have an optimal temperature closer to that of the warm water at which they have the greatest reaction velocity.
Explanation:
Enzymes function best at a specific pH and temperature. This is due to the chemical characteristics of the enzyme. In this case it was observed that the enzyme was able to clean better at a higher temperature. To test this you could measure the reaction velocities using a kinetic enzyme assay that uses a spectrophotometer to measure the absorbance of a sample over a period of time to record the change. The independent variable would be the temperature.

glucose-6-phosphate dehydrogenase deficiency (g6pd) is inherited as an x-linked recessive allele in humans. a woman whose father suffered from g6pd marries a normal man. what proportion of their sons is expected to be g6pd?
0.25 of their sons is expected to be g6pd.
Because the sons will inherit only one of their mother's two X chromosomes. The father is normal, so he will pass on a normal allele. The mother has an X-linked recessive allele, so she can only pass on that allele to her daughters, who will not have G6PD deficiency.
The sons will have a 50% chance of inheriting the X chromosome from their mother—that is, they'll get either the normal or G6PD-deficient allele from her. If they get the normal allele from her, then they'll be fine and won't be affected by G6PD deficiency. If they get the G6PD-deficient allele from her, then they'll have G6PD deficiency themselves and be affected by it.

individuals contain genes that are unique to the individual. the genes are coded into mRNA and in the ribosomes the mRNA are read form tRNA to assemble amino acids and form a polypeptide chain which is modified further to form protein molecules. these proteins molecules form structures, enzymes and hormones which contribute to the individual's traits such as hair structures, digestive traits and body structures too.
therefore, proteins made off the genes in an individual determine their traits
Why is competition is a density-dependent?
The effect of the competition is frequently density-dependent, meaning that with higher population densities, competition increases. This is due to the fact that rivalry frequently becomes more intense as the population grows (or as resources decline).
What are density-dependent factors?Intraspecific competition, which occurs when members of the same species compete with one another for resources like food and space, is unaffected by factors like population density. Regardless of population size, all species populations in the same habitat will experience a comparable impact. Weather, climate, and natural catastrophes are some of the contributing factors.
Examples of factors that are influenced by density include disease, competition, and predation. The relationship between population size and characteristics that depend on density can be positive or negative. These population-size-related growth-restraining factors are positively correlated with population size and get stronger as the population expands.

when people have a bacterial infection, pyrogens are often released to maintain elevated body temperature, which helps kill the bacteria causing the infection. which answer option is the most likely action of pyrogens on thermoregulation?
The most likely action of pyrogens on thermoregulation is that these substances will reset the set point of the sensors and cause the death of the bacteria.
Endogenous pyrogens are substances that are released into the blood when phagocytic leukocytes kill a bacterium. The hypothalamus receives these pyrogens and the thermostat (sensors) is reset. This enables the condition known as a fever, in which the body's temperature rises. A nutrient required by bacteria is reduced as a result of iron becoming more conserved when body temperature rises.
The pathogen may also be killed by heat itself. The hypothalamus regulates body temperature through reflexes that result in sweating and vasodilation when the body is too warm or shivering and vasoconstriction when the body is too cold. It responds to bodily substances.
