3 0

Answer and Explanation:

The Immune System. It comprises the white blood cells, lymphatic system, etc. The immune response is the production of antibodies in response to antigens present in pathogens and other foreign matter.

The leukocytes are formed in the bone marrow of long bones and lymph nodes. Their function is to protect the body from invasion of foreign material like bacteria and viruses( pathogens). They help fight against infections by engulfing and digesting pathogens and production of antibodies which are proteins that bind to pathogens. Their number increases greatly during infections.

3. What determines how many species live in a given place? And, what
Tasya [4]

Answer: Every stable population has one or more factors that limit its growth. A limiting factor determines the carrying capacity for a species. A limiting factor can be any biotic or abiotic factor: nutrient, space, and water availability are examples. The size of a population is tied to its limiting factor.  The environment, what food is there and what predators live there. How much food they get and if they are decreasing from weather, predators etc.

According to your worldview, what value does a human person have? How does your position affect your stance on controversial bio
nalin [4]

A human life is so valuable that no single price should be placed on it. The effect on this stance on bioethical issues however, is relative.

<h3>Relativity of Human value to Bioethical issues</h3>
  • A person's stance on a bioethical issue can be based on which human life they value more, the person that will gain, or the one that will be affected.
  • With abortion, one might argue that the value of the mother is higher than the baby's because not having to take care of a child will give her a better life.
  • Designer babies might be more valuable because their lower rate of birth defects mean that they are tougher and less expensive to maintain.
  • Stem cell research could save many lives so more value might be placed on these lives than the embryos affected.

In conclusion, a person can see another life as valuable yet have relative views on bioethical issues.

The RNA meets with the organelle ribosome that will read it to build a polypeptide chain of amino acids, following the process o
konstantin123 [22]

The rough endoplasmic reticulum (RER) is is a series of flattened sacs connected to ribosomes. The Golgi Apparatus is an organelle composed of flattened stacked pouches known as <em>cisternae</em>.

In this case, the missing words indicate:

  • Specifically, this organelle is attached on the ROUGH ENDOPLASMIC RETICULUM (RER) which will help to modify and package the polypeptide product.
  • It puts it into a transport vesicle to be sent over to the GOLGI APPARATUS  to add molecular tags and sort it, like a post office.

  • The RER is required for the production and secretion of different hormones and proteins.

  • The Golgi apparatus plays fundamental roles associated with the transport, modification, and packaging of proteins and lipids into vesicles, which are subsequently delivered to specific cellular destinations.

  • Both the RER and Golgi apparatus form part of the endomembrane system.

Sonbull [250]

The answer is charged amino acid group.

<span>Grouping of amino acid into one of three categories are only based on its R group. And there is an amino and carboxyl group are present in the amino acid that are ionized so we can say that amino acid is technically charged and there is one thing to remember that Amino acids that are classified as polar, they are not having any charge.</span>
