Answer:
The correct answer is - 2. Serve a different function
Explanation:
In a multicellular organism there are different type of the cells present and termed and differentiat on the basis of their specific function in the body or the location in the body. The different type of cells present are epithelilal cell, nerve cells, connective tissue cell and muscle cell. These cells can be further divided on their function as well such as cardiac cell, hepatic cell, nephron cells and neurons and many other cells.
All these specialized cell peroform their own function in the body such as nephrons helps in blood purification, hepatic cells help in various functon include synthesis of bile and hormones and metabolism. Cardiac muscles made up of cells that helps in puming the blood and mainataining blood flow.

If more individuals are born with the advantageous trait in each generation, over time what do you predict will happen to the percentage (%) of the alleles (gene variety) that code for this trait in the population?
Answer:
The percentage (%) of the alleles that code for this trait in the population will increase, as more individuals are born with the trait.
Explanation:
The more individuals get born expressing the trait, the higher its frequency gets in the population. By generation, there are more individuals carrying the allele for the advantageous trait. These individuals reproduce and increase the probabilities of the progeny to inherit the mentioned allele. When this sequence keeps occurring in the population over many generations, the allele percentage will increase. On the other hand, the other allele or alleles will decrease. Probably, if there are no changes that might influence or affect this pattern, the alleles for the advantageous trait will fixate, while the other allele might get lost.

i need help with this can someone help me?
Explanation:
Predation plays an important role in the overall health of an ecosystem since it regulates the population of preys as well as maintain the population of higher-level consumers. If predators were eliminated from an ecosystem, it would cause an increase of the population of preys and potentially decrease the population of other organisms on lower trophic levels. An example of such effect can be seen from the population of rabbits and plants supposing that foxes, eagles and snakes are eliminated from the ecosystem. The rabbit population will multiply, causing a decrease in the population of plants such as grass that rabbits feed on.

Artificial selection has produced a wide variety of crop plants, livestock, and pets. Which characteristic of artificial selection makes it different from natural selection
Answer:
Genetic Problems
Explanation:
When people genetically modify animals, they can mess up a lot of their natural abilities. For example in some cases scientist have made cows who produce more milk, but couldn't reproduce anymore because of it. Sometimes it even hurts the animal. People have bred dogs in certain ways that makes it hard for them to breathe, like Bull dogs who has respiratory issues. This makes decreases their life span and continuing to bred them will only make it worse. When scientist have a certain trait they want they also make animals breed with their own families. Incest creates a lot of genetic problems.

What can you infer about an organism that lives in the rocky intertidal zone?
O A. They are able to withstand changes in tides.
O B. They are able to withstand changes in salinity.
OC. They are able to withstand changes in water temperature.
OD. They are able to withstand changes in air temperature.
Answer:
D
Explanation:
An organism that lives in the rocky intertidal zone are able to withstand changes in tides, salinity, water temperature and air temperature. So, the correct options are All of the above.
What is Intertidal zone?The intertidal zone is the area where the sea meets the land between high and low tide. It is also known as foreshore. It has a wide variety of habitats with different species of life such as sea stars, sea urchins and many species of coral with regional differences in biodiversity.
The intertidal zone is an ecosystem found along the ocean. In this, innumerable organisms living on the coast are saved from the change between high and low tide.
Challenges which are faces in intertidal zone include:

Students are conducting a lab estimating the time it takes for the cell cycle in normal chicken cells. They find that the average time for one complete cell cycle is 22 hours.
What differences would they expect to see in cancerous chicken cells?
A Cancerous chicken cells will spend more time in interphase.
b Cancerous cells will not complete all phases of the cell cycle.
c Cancerous chicken cells will complete mitosis in a shorter amount of time.
d Cancerous chicken cells and normal cells will have the same total time to complete the cell cycle.
Answer:C!
Explanation:
Cancerous chicken cells will complete mitosis in a shorter amount of time.
The difference they would expect to see in cancerous chicken cells is cancerous chicken cells will complete mitosis in a shorter amount of time. The correct option is c.
What are cancerous cells?Cancerous cells are those cells that cause cancer in organisms. These cells are the converted form of normal cells. The normal cells are converted into cancerous cells by the means of mutagens.
The cell cycle is the cycle of the division of a cell. The cell divides itself and forms a new daughter cell. That's how a body increases the older cells to divide and produce new cells. The process is called mitosis.
Now, the normal cells divide at a constant and normal rate that is needed, but the cancerous cells divided abnormally and rapidly which cause tumor in the body.
Thus, the correct option is c. Cancerous chicken cells will complete mitosis in a shorter amount of time.

What is the best way to describe the concept of “homeostasis”.
A strand of messenger RNA is attached to a ribosome and is directing protein synthesis. The next exposed codon of this messenger RNA has the code GAA. It is most likely to bond with a transfer RNA that has which amino acid?
Answer:
Glutamic acid or Glutamate
Explanation:
This question is describing the process of TRANSLATION, which is the process by which protein is synthesized from a mRNA template. In the process of translation, a molecule called transfer RNA (tRNA) reads mRNA codons and carries its corresponding amino acid to the growing polypeptide chain.
According to this question, strand of messenger RNA is undergoing translation in the ribosome. However, the next exposed codon of this messenger RNA has the code GAA. A tRNA carrying an amino acid that corresponds to the codon GAA will attach to it. This amino acid is GLUTAMIC ACID.
N.B: codon GAA encodes amino acid GLUTAMIC ACID
