Why do the blood vessels going to the skin and internal digestive organs constrict and get smaller during a fight-or-flight response?
a to let in more light
b to allow the body to take in more oxygen
c to redirect blood to the areas that are involved in the panic response
d to increase blood flow

Answers

Answer 1

Answer:

Theres the answer.

Explanation:

The sympathetic division can be thought of in a general way as helping the body to mount a “fight or flight” response, with an overall increase in heart rate and blood pressure. Pressure increases because blood vessels constrict under sympathetic stimulation.

All of the following describe outcomes of urbanization except
O decreased soil pollution
O food chain disruption in a natural habitat
O increased wastewater from sewage drainage
O loss of plant biodiversity

Answers

Answer:

O decreased soil pollution

Explanation:

Urbanization does not lead to decreased soil pollution.

Pollution is the introduction of contaminants into the environments. As urbanization progresses and the population of people in a place increases, soil pollution increases.

Also, industrial expansion causes increased production of wastes. So, some of these wastes find their way into the environment of which the soil is a main component. There is an increased amount of soil pollution.

Pick only ONE sentence Which sentence from the section shows why the right temperature is important for plants? (A) Temperature can also affect a plant (B) As with any living thing, a plant has an optimal temperature range at which it grows and preforms best (C) It may not be able to take in enough water and nutrients through it's roots (D) Too much heat can cause plant cells to break down, a process called denaturation.

Answers

Answer:

The correct answer is - (B) As with any living thing, a plant has an optimal temperature range at which it grows and performs best.

Explanation:

Like any other or most of the living organism, plants also required an optimal temperature range as they also required appropriate temperature for their growth and development and perform their functions at their best.

Optimum temperature range is a temperature range at which something performs its best similarly plants perform their cellular functions like photosynthesis, metabolism, reproduction, and many other functions that require a particular temperature range.

Photosynthesis and respiration recycle carbon in plants. Animals get carbon from plants and exhale it. Therefore, option (B) is correct.

What is carbon cycle?

The biogeochemical process known as the carbon cycle involves the transfer of carbon between the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Carbon is the most common element found in organic compounds, and it also plays a significant role in the chemical makeup of numerous minerals, including limestone.

Through the process of photosynthesis, plants take in carbon from their surroundings and then release it during the process of respiration. Plants are the source of carbon for animals, and animals exhale carbon during the process of respiration.

Therefore , option (B) best explains the roles plants and animals play in recycling carbon.

in a chemical reaction bonds in the reactants molecules are broken and new bonds are formed to yield products. how does an enzyme make this happen an optimal rate in a cell?

Answers

Answer:

A. It increases the amount of energy needed to break the bonds in the substrate.

Explanation:

Enzymes are known to be protein-based catalyst. It helps to speed up the chemical reactions that take place in the human body. They actually bind molecules and work in ways to alter chemical reactions. These enzymes are needed for food digestion, reproduction, healing diseases, blood coagulation, etc.

Enzymes help to increase the rate of reaction by lowering the activation energy. Certain enzymes can work to convert substrate to product at million of times faster. As a catalyst, it increases the energy needed to break bonds found in the substrate. This makes the reaction to occur at a faster rate.

Which of the following scenarios can be classified as a negative feedback loop?
a increase in blood pressure to reduce heart rate
b increase in testosterone to help increase a fight-or-flight response
c increase in oxytocin caused by increased contractions
d increase in platelet production to help increase blood clotting

Answers

Answer:

The scenario that can be considered an example of a negative feedback loop is increase in platelet production to help increase blood clotting (option d).

Explanation:

Negative feedback loop is what occurs when a change occurs in the body, producing a response that decreases or stops that change, with the intention of maintaining homeostasis.

When there is a wound that produces bleeding, a series of mechanisms are activated, the coagulation cascade, which promotes the release of factors that allow the formation of clots. The increased release of platelets implies negative feedback because it helps to stop the change that occurs in the body, the loss of blood, through the formation of clots.

One thing that can cause confusion is the fact that this response also involves positive, though limited, feedback that promotes the production of clotting factors and platelets to increase clot formation. What really happens is that the positive feedback promotes the general feedback, which is the negative feedback: clot formation to stop the bleeding, restoring homeostasis.

The other options are not correct because:

    a. Increase in blood pressure to reduce heart rate is not possible.

    b. In the fight and flight response the hormones involved are cortisol and adrenaline, not testosterone.

    c. Increased oxytocin in response to uterine contractions is positive feedback.

Answer:

A is the answer Not D

increase in blood pressure to reduce heart rate
