Absorption is the process of transferring digested food from intestinal membranes into the blood circulation, which takes most nutrients straight to the liver for further processing and/or storage. That is option D.
Liver is one of the largest visceral organs of the body that helps in the metabolism of nutrients.
After the ingestion of food, absorption takes place which is the process of transferring digested food from intestinal membranes into the blood circulation.
The nutrients must pass straight to the liver for metabolism.

Answer:
The endosymbiotic event that brought chloroplast in eukaryotic cells happened after the lineage delivered.
Explanation:
The endosymbiotic theory says that the ancestral cell gains the ability of photosynthesis when it engulfed a photosynthetic bacteria and this bacteria remained in a symbiotic relationship with the ancestral cell and evolved as chloroplast in plants that can perform photosynthesis.
All the eukaryotes do not have this internal structure like chloroplast because this endosymbiotic event must be happened after the divergence of the lineage into different groups. Therefore plant cells have chloroplast and animals cell do not have.
The question is incomplete as it does not have the options which are provided in the attached picture.
Answer:
Option-B
Explanation:
The theory of the endosymbiotic origin of eukaryotes proposed that the organelles like the chloroplast and mitochondria are originated when the proto-eukaryotes engulfed the prokaryotic cells.
The chloroplast was formed in some eukaryotes instead of others as the proto eukaryotes diverged into many lineages before the origin of the chloroplast in them. One of the lineages engulfed the chloroplast and become photosynthetic organism but rest of the proto eukaryotic lineage did no engulfed the bacteria and did not possess the chloroplast.
Thus, Option-B is the correct answer.
Answer:
A genetic disorder is a disease that is caused by the change in the sequence of DNA. Down Syndrom and Huntington disease are two examples of genetic disorders.
Explanation:
A genetic disorder is a change in the sequence of the DNA that results in a disease or condition. These disorders are caused by the mutation of one or multiple genes, by damage in chromosomes, or by environmental factors.
Down syndrome is a known genetic disorder where there is an extra copy of chromosome 21 instead of the two copies. People with Down Syndrom have intellectual difficulties and a different physical complexion that can lead to some problems.
Huntington disease is a genetic disorder that causes the degeneration of neurons, which brings emotional, cognitive, and movement problems that worsen with time since it is a progressive disease.

Identify the variables.
Write out your hypothesis in an if/then format.
Gather your materials.
Analyze the data.
Write your conclusion.
The correct order of steps in an experiment would be:
An experiment is a term to refer to the process by which a hypothesis is supported/disproved. The experiments serve to explain the cause-and-effect relationship according to the results obtained.
Experimentation has some important steps that we must follow to demonstrate our ideas regarding a scientific manifestation, these steps are:

Answer:
b
Explanation:
b. Helper T cells
c. Antibodies
d. Natural killer cells
Answer:
Cytotoxic T cells
Explanation:
Perforin is the cytosolic protein and upon degranulation forms pores in the target cell. Perforin protein helps in the transport of water and ions.
Perforin is present in the granules of cytotoxic T cells. These cells have the ability to kill virus infected cells and cancer cells. Cytotoxic T cells bind with the class 1 MHC molecules. These cells are also known as CD8+ T cells.
Thus, the correct answer is option (A).
