1. Color can affect a pocket mouse’s ability to survive because if a light colored mouse is in a dark area, it will not survive. A dark colored mouse will survive in a dark area because it will blend in with its surroundings.
2. On the dark rock, mice with dark fur are more likely to survive because they will blend in with the rock.
The primary reason that osteoporosis accelerates after menopause in women is: * 2 points A. Increased osteoblast activity. B. Reduced levels of vitamin C. C. Diminished osteoclast activity. D. Reduced levels of circulating estrogens.
Answer:
The correct answer is D. Reduced levels of circulating estrogens.
Explanation:
Estrogens prevent the loss of calcium and ensure its proper mineralization, thus preventing the bones from becoming brittle, maintaining the consistency of the skeleton and preventing osteoporosis. Osteoporosis is a skeletal disease in which there is a decrease in bone mass density. Thus, the bones become more porous, the number and size of the cavities or cells that exist inside them increases, they are more fragile, they resist shocks worse and they break more easily. Menopause is the definitive cessation of ovarian function that, externally, results in the disappearance of the menses and usually occurs around 50 years (the interval goes from 45 to 55 years). It is the gradual loss of calcium in the bones, which accelerates in the first years of menopause due to estrogen deficiency. At the beginning of the disease, there are no symptoms and, as it progresses, there is a tendency to suffer fractures, which leads to a decrease in height.

Which point shows the prevailing westerlies?
O1
O 2
O3
O4
Answer:
1
Explanation:
Prevailing Westerlies are the winds in the middle latitudes between 35 and 65 degrees latitude. They tend to blow from the high pressure area in the horse latitudes towards the poles. These prevailing winds blow from the west to the east steering extra-tropical cyclones in this general manner.

can virus show response against heat, chemical and temperature?If yes then how?
Answer:
Yes, anything can respond to heat and against heat and temp and maybe chemicals including a virus.
Explanation:
The virus can mutate and develop new genes to bounce back the chemical or the heat and temps, it could respond differently than an un-mutated virus because it has adapted to those environments

A cell with 20 chromosomes undergoes MEIOSIS. Which of these statements is true?
1 Point)
a. 4 daughter cells will be created and each daughter cell will have 10 chromosomes.
b. 2 daughter cells will be created and each daughter cell will have 10 chromosomes.
c. 4 daughter cells will be created and each daughter cell will have 20 chromosomes.
d. 2 daughter cells will be created and each daughter cell will have 20 chromosomes.
Answer:
A.
Explanation:
By the end of meiosis 4 daughter cells will be produced with half the amount of chromosomes the original parent cell has, haploid.
A cell with 20 chromosomes undergoes meiosis produces 4 daughter cells and each daughter cell will have 10 chromosomes. Thus option A is correct.
What is Meiosis?The cell division in which a cell divides twice to form four haploid daughter cells called as Meiosis.
The cell division occur in two steps nuclear division or karyokinesis and cytoplasmic division called as cytokinesis.
This type of cell division are seen in sexually-reproducing organisms mostly germ cells.
During reproduction diploid organism produces haploid number of gametes such as egg and sperm.
The gametes unite to create a new zygote with the same number of alleles as the parents.
The meiosis occur in 2 stages that is meiosis I, meiosis II and Each stage is classified into several phases such as Prophase, Metaphase, Anaphase, Telophase, Cytokinesis.
Prophase I of meiosis I can have five subphrases, such as Leptotene, Zygotene, Pachytene, Diplotene and Diakinesis.
Hence, option A is correct.

Explanation:
The muscle cells of a basketball player are examined after an injury that required her to be placed on the injured list. Muscle cells require a lot of energy to function. The number of organelles in her cells are counted. Which of the following findings are most likely to occur after 6 months of required rest and inactivity?
Answer:
D) The number of mitochondria has decreased due to long period of rest
Explanation:
The cell organelles perform various functions in a cell. For example, the nucleus contains the genetic material of the cell, the ribosome function in protein synthesis, the mitochondria is the site for ATP synthesis, etc.
An athlete such as a basketball player requires a lot of energy for his/her activities. This energy is provided through the contraction and relaxing of muscle fibres. The mitochondria, the cell organelle required for energy synthesis will be present in very large numbers in the athlete's muscle cells in order to provide him/her with the required energy.
However, in the case of an injured athlete who has been out of action for 6 months, there would be a reduction in the number of mitochondria in the muscles due to this long period of inactivity.
Therefore, the correct option is D; The number of mitochondria has decreased due to long period of rest.

Protein or lysine amino acid is not a part of the deoxyribonucleic acid (DNA) nucleotide.
What is a nucleotide?A nucleotide can be defined as the subunit of deoxyribonucleic acid (DNA) or ribonucleic acid (RNA) which contains a nitrogenous base.
Furthermore, deoxyribonucleotides which is the basic unit of a deoxyribonucleic acid (DNA) typically comprises the following:
A nitrogenous base.A phosphate group.Deoxyribose sugar (5-carbon sugar).In conclusion, we can deduce that protein or lysine amino acid isn't a part of the deoxyribonucleic acid (DNA) nucleotide.
