56:47 If you wanted to increase your muscular endurance, it would be important to participate in activities that __________. A. increase the size of the muscle cells and the amount of blood that is delivered to the muscle B. decrease the amount of fuel that the muscle can store and increase the time it takes for the muscle to contract C. increase the number of muscles and decrease the size of the muscle cells D. decrease the length of the muscle and increase the thickness of the muscle
Answers
Answer:
The correct answer is - A. increase the size of the muscle cells and the amount of blood that is delivered to the muscle.
Explanation:
Muscular endurance is the ability of a muscle to do some work or exert force continuously and rapidly for a period of time. To increase muscular endurance no heavy exercise required by including exercises that can help in increasing the size of the muscle cells and the amount of blood that is delivered to the muscle. The size of cells and delivering a high amount of blood helps in getting more oxygen and perform the metabolic activity more and generate more energy. So including the exercise rapidly and continuously will help in increasing the muscle cells.
A scientist is comparing the sequences of related genes among three species. Two of the species have very similar sequences, while the sequence of the third species differs greatly from the others. T
Answers
Hi. The question you presented above is incomplete. This makes it impossible for this question to be answered. However, when searching for your question on the internet, I was able to find another question exactly like yours, which asked you to explain the evolutionary relationship between these three species. If that's the case for you, I hope the answer below will help you.
In a simplified way, we can infer that among the three species presented above, the third presented a faster evolution than the first two and this is what explains the difference between the gene sequences between the species. As the question presents, the three species have related genes, which indicates that they had a common ancestor, however the difference in the gene sequence of the third species shows that it evolved first, showing changes that cannot be noticed in the first two species that are evolving more slowly.

The reason for the length of day and night is the diurnal rotation because the sun cannot illuminate the whole earth at once when the earth is lit on one side it is day and when it is on the other side it is night
Answers
Answer:
Yes.
Explanation:
Yes, the sun cannot illuminate the whole earth at once when the earth is lit on one side it is day and when it is on the other side it is night. The earth rotates on its own axis which causes change of day and night. Due to this rotation, those areas which are in front of sun experience day while on the other hand, the shade part of the earth causes night at that part so we can say that diurnal rotation is responsible for day and night.

Deforestation occurs when large Amounts of trees are cut down and not replaced which of the following would result from deforestation
A. Decrease carbon in the atmosphere
B. Increased carbon in the atmosphere
Answers
Answer:
The correct answer is (B).
Explanation:
Deforestation occurs when large Amounts of trees are cut down and not replaced, which of the following would result from deforestation...
Increased carbon in the atmosphere
This statement is true because when trees become less abundant, the amount of oxygen being released into the atmosphere by trees via photosynthesis.
The circumstance that would result from deforestation is the increased carbon in the atmosphere. Thus, the correct option is B.
What is Deforestation?Deforestation may be defined as the process of cutting down or eliminating trees in large numbers from our surroundings. This activity generally happens due to industrialization, wood extraction, urbanization, etc.
When the number of trees remains less in the environment due to deforestation or any other activity, the level of carbon dioxide in the atmosphere typically rises.
This is because carbon dioxide is considered the reactant of photosynthesis that is utilized by the plants along with water in the presence of sunlight and converted into oxygen.
But when the number of plants decreases, the level of carbon in the atmosphere increases, and the level of oxygen in the atmosphere decreases.
Therefore, the circumstance that would result from deforestation is the increased carbon in the atmosphere. Thus, the correct option is B.

insulin and glucagon are produced in the;
Answers
Glucagon is a peptide hormone, PRODUCED by alpha cells of the pancreas.
Insulin is a hormone made by an organ located behind the stomach called the pancreas. There are specialised areas within the pancreas called islets of Langerhans (the term insulin comes from the Latin insula that means island).
And Islet cells in the pancreas are responsible for releasing both insulin and glucagon.
Glucagon raises concentration of glucose and fatty acids in the bloodstream, and is considered to be the main catabolic hormone of the body.[3] It is also used as a medication to treat a number of health conditions. Its effect is opposite to that of insulin, which lowers extracellular glucose.[4] It is produced from proglucagon, encoded by the GCG gene.

All of the following affect the temperature at which magma forms except what?
Answers
Except viscosity, all the other factors affect the temperature at which magma forms. Therefore, the correct option is D.
What is viscosity?Viscosity can be defined as a measure of the fluid's resistance to flow. Magma can be defined as a very hot molten or semi-molten substance that is formed due to volcanic eruptions. They are responsible for the formation of the igneous rocks.
There are many factors that affect the temperature at which magma forms:
Pressure-increasing pressure can raise the melting temperature of rocks, while decreasing pressure can lower it.Composition of source material: The composition of the rocks in the mantle can vary depending on the location and geological history of the region. Presence of water: Water can lower the melting point of rocks, which can lead to the formation of magma.But viscosity does not play any role in impacting the temperature at which magma forms. Therefore, the correct option is D.
