Snakes, dogs, and humans have a vertebral column. Snakes and dogs have tails, and humans have vestigial tailbones. Dogs and humans have limbs, but snakes do not. Most reptiles lay eggs, but a few give birth to live young. What do these structures suggest about the evolutionary pattern between the three organisms?
A Snakes and dogs are more closely related than snakes and humans.
B Snakes and humans are more closely related than humans and dogs.
C Dogs and humans are more closely related than snakes and humans.
D Dogs, snakes, and humans share a common ancestor.
E The early ancestor of snakes and dogs is the same, and the early ancestor of humans is different.

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.

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.

Which two body systems maintain the level of glucose in the blood?
Answer:
The endocrine functions of the pancreas and liver coordinate efforts to maintain normal blood glucose levels.
The pancreas and liver regulate the level of glucose in the blood.
What is diabetes?Maintaining blood glucose is important for the body. The body needs glucose for the production of energy. The inability of the body to regulate blood glucose results is a result of diabetes. The blood glucose in our body is maintained by two hormones.
Insulin reduces the amount of glucose in the blood and glucagon increases the amount of glucose in the blood. Insulin and glucagon work together, in people without diabetes to maintain the blood glucose level of the body.
But in people affected by diabetes, insulin has either stopped working or insulin production by the body is inadequate compared to the body's requirements.
In type 2 diabetes, insulin production is low and in type 1 diabetes, there is resistance to insulin.
Insulin and glucagon are produced by the islets of Langerhans cells of the pancreas. In excess of insulin, the liver stores glucose from the blood, and in excess of glucagon, glucose is released by the liver into the blood.
Therefore, the pancreas and liver regulate the level of glucose in the blood.

what is an advantage of external fertilization?
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.

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.
