Answer:
The number of habitats falls below a critical level.
Explanation:
The possible reason for extinction is that the number of habitats falls below a critical level. This makes it impossible for organisms to survive.
A habitat is the dwelling place of living organism in an ecosystem. The resources and other materials that ensures the survival of an organism are made available in the habitat. When a habitat begins to thin out and can no longer support organisms, then extinction will ensue.❗️❗️please if you can help me with this let me know. i have 10 pages of multiple choice chemistry questions and i can mark brainliest, and pay you real money if you do it

Explain how osmosis causes a red blood cell to become hypertonic, become hypotonic, or remain isotonic with the blood.
Answer:
Water moves into and out of cells by osmosis. If a cell is in a hypertonic solution, the solution has a lower water concentration than the cell cytosol, and water moves out of the cell until both solutions are isotonic..............

In order to test Lee for a genetic disorder, Dr. Aikenhed will probably take a sample of cells containing his genomic DNA by swabbing his cheek or taking a blood sample. Why is it important to use non-cancerous cells to test Lee for a genetic disorder instead of the biopsy tissue?
Answer:
Cancer is a chronic disease in which cells reproduce abnormally, exceeding the capacity of the body tissues to assimilate such reproduction, which causes alterations in these cells and in the organs they affect.
Therefore, if a sample is required to determine some type of genetic disorder in the patient, non-cancerous cells should be used, since these will contain genetic material free of any alteration caused by said disease and, therefore, will be a test of greater accuracy to determine said disorder.
It is very essential then to look the genetic makeup to normal cells and compare them to see as it could help in choosing personalized therapy for Lee.
Cancer cell's genes are very unstable in nature and they replicate very fast speed. The use of non cancerous cells will better tell if the cancer is genetic or not when compared to the use of biopsy tissue.
Germline testing is often carried out to know if an individual has a gene mutation that can increase the risk of developing cancers.

O a. decides to not attend anymore parties until her friend returns the sweater she borrowed last winter
O b. discusses terms of surrender
O c. masks
O d. obliterates
Answer:
C. Masks
Explanation:
When we are talking about genetics dominance is a phenomenon of one allele of a gene on a chromosome that masks the effect of a different variant of the same gene on the other copy of the chromosome. Genes don't have parties and sweaters so A is not an option here. They also can't surrender and even if they did they couldn't discuss anything. And they most certainly don't obliterate each other.
What makes cellulose nondogestible to humans?
Answer:
Humans are unable to digest cellulose because the appropriate enzymes to breakdown the beta acetal linkages are lacking. (More on enzyme digestion in a later chapter.) Undigestible cellulose is the fiber which aids in the smooth working of the intestinal tract. ... No vertebrate can digest cellulose directly.
