These structures suggest that Dogs and humans are more closely related than snakes and humans.

Does snake have backbone?

Yes, snakes have a backbone. The backbone is made up of a series of bones called vertebrae, which are connected by ligaments and muscles. The vertebrae of a snake are unique because they are loosely connected, allowing the snake to move and bend in a wide variety of directions.

Dogs and humans are more closely related than snakes and humans because they both have vertebral columns, tails, and limbs while snakes only have a vertebral column and a tail. This suggests that a common ancestor shared these features with both dogs and humans, while the common ancestor of snakes did not possess these features.

Therefore, Dogs and humans are more closely related than snakes and humans is the correct answer.

Dogs, snakes, and humans share a common ancestor. The presence of a vertebral column in all three organisms suggests that they belong to the same group of vertebrates,

So the correct answer is D.  Dogs, snakes, and humans share a common ancestor.

What is a common ancestor?

A common ancestor is a hypothetical organism that is ancestral to two or more different groups of organisms. In other words, a common ancestor is an organism that gave rise to two or more distinct lineages through evolutionary divergence. All organisms that share a common ancestor are said to be related, and their evolutionary relationships can be represented as a branching tree-like diagram called a phylogenetic tree. The concept of a common ancestor is fundamental to evolutionary biology, as it allows scientists to infer the evolutionary history and relationships between different groups of organisms.

Dogs, snakes, and humans share a common ancestor. The presence of a vertebral column in all three organisms suggests that they belong to the same group of vertebrates, but differences in tails and limbs suggest that their ancestors underwent evolutionary changes that led to these differences.

Therefore, options A and C are partially correct but do not capture the full picture, while option B is incorrect. The correct answer is D.

Protein or lysine amino acid is not a part of the deoxyribonucleic acid (DNA) 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:

In conclusion, we can deduce that protein or lysine amino acid isn't a part of the deoxyribonucleic acid (DNA) nucleotide.

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.

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.

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.

Answer: Helps keep the species alive

Explanation:

When the eggs are externally fertilized, there is a greater chance for multiple  different males to fertilize the eggs. This gives Gene diversity, and helps keep the species alive. It may also help keep the eggs in good condition. For example, when fish lay eggs, the water helps keep the eggs moisturized.
