How would you explain the relationship between insulin and glucose

1 answer:

5 0

Insulin regulates the amount of glucose in the body, when glucose level reach a level that is too high, Beta cells release insulin from the pancreas, then fat cells absorb the glucose from the blood stream causing the blood glucose levels to balance out.

The majority of cells in a human body go through mitosis and not meiosis. Is this true or false?

Andru [333]

Answer:

True

Explanation:

Mitosis results in two cells that are genetically identical. DNA replication only occurs during "S phase." Meiosis is commonly defined as a type of cell division that divides a somatic cell and produces four gamete cells when doing so.

S phase: In S phase, the cell synthesizes a complete copy of the DNA in its nucleus. It also duplicates a microtubule-organizing structure called the centrosome. The centrosomes help separate DNA during M phase.

Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome.

A student does an experiment for a science fair to study whether temperature affects the timing of a cricketâ€™s chirps. The stu

nexus9112 [7]

The frequency of chirps increases as the temperature increases. The correct option is B. The chirps occur closer together as the temperature increases.

-------------------------------

<h2>Available data:</h2>

<h3>Data recorded by the student </h3>

Day Temperature Average time between chirps (sec)

1 21 2. 5

2 22 2. 6

3 23 2. 2

4 24 2. 3

5 25 2. 0

6 26 1. 8

7 27 1. 9

8 28 1. 8

9 29 1. 4

10 30 1. 2

11 31 1. 5

12 32 1. 1

In this experiment the student recorded the time in seconds between chirps.

We can see that as the temperature increases, in general, the time between chirps decreases.

At 21ºC the time between chirps is 2.5 seconds

At 26ºC the time between chirps is 1.8 seconds

At 32ºC the time between chirps is 1.1 seconds

According to this information, if the average time between chirps decreases with the temperature increase, we can assume that the frequency of chirps increases as the temperature gets higher.

<h3>Options,</h3>

A) The higher the temperature, the fewer chirps there will be in 10 seconds.

Wrong. The number of chirps in 10 seconds will depend, not only on the frequency but also on how long the chirps last. Since the student did not record the time of chirps, we can not make this conclusion.

B) The chirps occur closer together as the temperature increases.

True. The chirps increase in frequency as the temperature increases, so they occur closer together.

C) The chirps become farther apart as the temperature increases.

Wrong. We can see how the time between chirps decreases as temperature increases, meaning that they are closer not farther.

D) There is no relationship between temperature and the time between chirps.

Wrong. If we make a graph we will see the tendency and the relationship between chirps and temperature.

Graphs usually explain the relationship between variables. In this example, the relationship would be inverse.

how would the function of synovial joints be changed if they lacked joint cavities and the bones were united instead? Explain.

Anettt [7]

Answer:

In the absence of joint spaces (cavities) and bones fused together, body movements would be null or reduced.

Explanation:

The joints are the spaces where two bones meet, with cartilaginous tissue - articular cartilage and ligaments - to allow elasticity and body movements.

The articular cavities are spaces where bone union occurs through ligaments, surrounded by an articular capsule and upholstered inside by a membrane that produces liquid, the membrane and synovial fluid, respectively. These joints are usually found in the mobile body segments.

If the joint cavities did not exist, and the joints occurred between bone and bone, body mobility would not be possible. In the case of the skull bones, they do not have joint space, since their function is the protection of the organs of the central nervous system, not movement.
