Name 2 body systems that interact to maintain
homeostasis in the human body and explain how they do

Answers

Answer:

Internal Temperatures

Similarly, the cardiovascular, integumentary (skin and associated structures), respiratory, and muscular systems work together to help the body maintain a stable internal temperature. If body temperature rises, blood vessels in the skin dilate, allowing more blood to flow near the skin's surface.

OR,

The nervous and endocrine systems exert the ultimate control over homeostasis because they coordinate the functions of the body's systems. Regulation of body temperature, blood pressure, pH, and glucose concentration are four examples of how the body maintains homeostasis.

Which of the following describes how both of these cellular division processes maintain genetic continuity?
А.Both processes involve the replication and division of identical genetic material.
B. Both processes creates cells with half the genetic material of the parent cells.
C. Both process involve the recombination and division of new genetic material.
D. Both processes create cells with twice the genetic material of the parent cells.

Answers

Answer: Both processes involve the replication and division of identical genetic material

Explanation:

During S phase interphase DNA is replicated and it is replicated as an exact copy

When a single cell divides into two cells through mitosis, genetic continuity occurs. One cell divides into two during the process of mitosis, and each of the two progeny cells has the same amount of DNA as the parent cell.

What is genetic continuity?The fact that when a cell divides, the resulting two daughter cells have the same number and type of genes as the original cell is referred to as genetic continuity. It also describes how when two sexually reproducing organisms mate, their offspring have the same number of genes as the parents. Nuclear division results in daughter cells with identical sets of chromosomes. Mitosis ensures the genetic continuity of the ancestral cells in the body's daughter cells. It consists of one fully equational division followed by a DNA synthetic phase. Because it creates a perfect copy of DNA for new cells, DNA replication helps to maintain species genetic continuity.

From which hot spot would you view Polaris at an altitude of 45 degrees?

Answers

Answer:

Massena, New York

Explanation:

Polaris is most popularly known as the North star. It is also famous by the name of "Pole Star". It is the closet to the north celestial pole. At present it is the northern pole star currently.

It is found in the constellation of Ursa Minor. It is the one of the brightest star seen in the night sky. It is considered the star of the second magnitude which is situated close to the heaven's north pole.

The altitude of the Pole star or the Polaris when an observer is at the Tropic of Cancer is measured at 23.5 degree. While if the observer sees the Pole star at its zenith, the observer is located at the North Pole. i.e. 90 degree.

And the spot from where the observer views the Polaris at 45 degree altitude is Massena, New York.

In your opinion, what are the three most important molecules needed for the production of ATP? Explain your reasoning.

Answers

Three things that ATP does for cells are: Transport - mainly active transport or moving substances against a concentration gradient. Mechanical - described as muscle contractions, blood circulation and overall movement of cells.

To produce the energy required to drive ATP synthesis, the human body requires three different types of molecules: lipids, proteins, and carbohydrate.

What molecules are required for the production of ATP?

In the mitochondria of a cell, the process of cellular respiration also results in the formation of ATP.

This can be done through either anaerobic or aerobic respiration, depending on whether oxygen is present.

ATP is produced during aerobic respiration from glucose and oxygen, along with carbon dioxide and water.

ATP hydrolysis provides the energy needed for many essential processes in organisms and cells.

These include intracellular signaling, DNA and RNA synthesis, Adrenergic signaling, synaptic signaling, active transport, and muscle contraction.

Therefore, lipids, proteins, and carbohydrate are important molecules in production of ATP.
