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.

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.
Answers
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.

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.
Answers
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.
