In cats, the bones in the legs involved in
walking are very similar to the bones of
whales' flippers that are involved in
swimming. These are examples of -
F: analogous structures
G: homologous structures
H: vestigial structures
J: endosymbiosis
Answers: G
Answer:
Your answer is most likely G), so you are correct.
These are the example of Homologous structure. So, the correct option is (G).
What are different types of structures?Homologous structures are similar in structure and location, but perform different functions, resulting in divergent evolution. For example, An arm of a human, the leg of a dog or a flipper of a whale are all homologous structures.
Analogous structures are similar in function but have different origins and structures resulting in convergent evolution. For example, from wings in birds, bats and insects to fins in penguins and fishes are all analogous structures.
Structures with similar anatomy, morphology, embryology, and genetics, but dissimilar functions are known as homologous structures, while structures that are superficially similar but perform the same physiological function are referred to as analogous structures.
Thus. these are the example of Homologous structure. So, the correct option is (G).

during DNA replication, what unzips the DNA ?
A.mutagens
B.RNA
C.chromosomes
D.proteins
Answer:
Proteins
Explanation:
Helicases are enzymes that bind and may even remodel nucleic acid or nucleic acid protein complexes. There are DNA and RNA helicases. DNA helicases are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied.

If a cell has 14 chromosomes, how many chromosomes will each daughter cell have after mitosis and cytokinesis?
Why is this important?
Answer: After mitiosis, each daughter cell will also have 12 chromosomes. Cytokinesis is just the last stage of telophase, where the cell completely forms the two daughter cells. Telophase does not form chromosomes.
Explanation:
If a cell has 14 chromosomes, there are 14 chromosomes in each daughter cell.
What happens in Mitosis?There are four stages of mitosis: prophase, metaphase, anaphase and telophase.
1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres.
2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell)
3) Anaphase: sister chromatids are pulled to opposite poles of the cell
4) Telophase: nuclear envelope reforms, chromosomes unfold into chromatin, cytokinesis can begin.
If a cell has 14 chromosomes, there are 14 chromosomes in each daughter cell.

1. Describe the possible fates of blood lactate? (4 mrks)
2. Does gender affect the levels of lactate? If so, Why? (4mrks)
Answer:
1)When the oxygen level is low, carbohydrates break down for energy and produce lactic acid. Lactic acid levels rise with strenuous exercise or other conditions - such as heart failure, severe infection (sepsis), or shock - which reduces the flow of blood and oxygen throughout the body.
2) no gender differences in resting or peak blood lactate concentrations, nor in the rate of blood lactate removal of young adult men and women with similar aerobic fitness level expressed as ml.kg FFW1

High cholesterol and triglycerides may indicate cardiovascular disease. What happens when cholesterol and other lipids are deposited in artery walls?
Answer:
With high cholesterol, you can develop fatty deposits in your blood vessels. Eventually, these deposits grow, making it difficult for enough blood to flow through your arteries. Sometimes, those deposits can break suddenly and form a clot that causes a heart attack or stroke.
How do high-energy electrons from glycolysis and the Krebs cycle contribute to the formation of ATP from ADP in the electron transport chain?
O
A. High-energy electrons interact with pyruvic acid to create a phosphate bond with ADP, forming ATP.
O
B. High-energy electrons supply the needed energy to synthesize ATP from the lower-energy ADP in the electron transport chain
C. High-energy electrons supply a negative charge which causes the citric acid to oxidize, forming a phosphate group to bond with ADP.
O
D. High-energy electrons increase the temperature of ADP so it easily reacts to form ATP.
Answer:
b
Explanation:
High-energy electrons supply the needed energy to synthesize ATP from the lower-energy ADP in the electron transport chain. So, the correct option is (B).
What is Electron transport chain?An electron transport chain is defined as a series of protein complexes and other molecules that transfer electrons from electron donors to electron acceptors through redox reactions and that link this electron transfer with the transfer of protons across a membrane.
Large amounts of ATP can be produced through a highly efficient method called oxidative phosphorylation where ATP is a fundamental unit of the metabolic process. Electrons are transferred from electron donor to electron acceptor thereby producing ATP which is the important step of Electron transport chain.
Thus, high-energy electrons supply the needed energy to synthesize ATP from the lower-energy ADP in the electron transport chain. So, the correct option is (B).

He has been feeling good and has not noticed any changes in his health. He does not understand why he has diabetes but this brother does not and why he has not had any noticeable symptoms. How would you explain this to him? Describe what the glycemic index is and how this is very important in developing a nutritional diet.
Answer:
The glycemic index allows people with diabetes to follow a balanced diet by consuming foods with a low glycemic index, which helps to avoid increasing the level of sugar in the blood.
Explanation:
The glycemic index is important to know when a certain food raises the level of sugar in the blood.
A good diet for people with diabetes is determined by foods that have a low glycemic index between 1 to 55; Some of the foods that can help us regulate the level of sugar in the blood are the following:
- Breads and cereals that are exclusively whole grains.
-Legumes like beans and lentils.
-Fruits such as: peach, pear, apples, cherries and prunes.
