Why do scientist use models

Biology
1 answer:
Maurinko [17]3 years ago
5 0

Explanation:

A model is used to help scientists visualise things that they cannot actually see. It can be thought of as a thinking tool, to help form explanations. Models are useful simplifications to aid understanding. ... It can then be used to explain further phenomena and to make predictions of future behaviour.

How does the ratio of the two types of melanin you have affect your skin color?
AfilCa [17]

Answer:

Pigmentation of the skin results from the accumulation of melanin-containing melanosomes in the basal layer of the epidermis. Differences in skin pigmentation result both from the relative ratio of eumelanin (brown–black) to pheomelanin (yellow–red), as well as the number of melanosomes within melanocytes.

it requires 12 hours to fill 3/5 of a swimming pool at this rate how many hours is required to fill the remainder pool
emmasim [6.3K]
So if you take the 12 hours that it takes to fill the swimming pool 3/5 way then u divide 12 by 3 and you would get 4 which would mean each quarter took 4 hours then it would take 8 more hours to fill the rest of the swimming pool

To survive, an organism must be able to maintain stable internal conditions in a changing environment. This process is called ho
Reptile [31]

Answer:

1. Initial air temperature: 0 °C (32 °F)

2. Initial body temperature: 37 °C (99 °F)

3. The expected effect of different factors on body temperature are:

   A. Raising air temperature: Increase

   B. Lowering air temperature: Decrease

   C. Adding clothing: Increase

   D. Exercising: Increase

Explanation:

The question is incomplete, it is necessary to look for a software related to this homework.

<u>Homeostasis is a property of organisms that consists in their capacity to maintain a stable internal condition by compensating for changes in their environment</u> through the regulated exchange of matter and energy with the exterior. It is a a dynamic equilibrium controlled by a mechanism of feedback that constitute the self-regulating mechanisms. Examples of homeostasis are temperature regulation and the balance between acidity and alkalinity (pH)

The Human Homeostasis Gizmo™ is a software that allows you to explore  how the human body stays at a nearly constant  temperature in different conditions.  To use it, you have to set the air temperature at 0 °C (32 °F) and the body temperature at 37 °C (99 °F), and click Play. After a simulation of 1 hour, then click Pause and gather the information. Then, do the same cprocedure  to test the effect of other factors and Click Reset between each trial. To determine the effect of different factors on body temperature, you have to compare the  final body temperature to the final body temperature while  there is no specific movement or change.

Then:

1. Initial air temperature: 0 °C (32 °F)

2. Initial body temperature: 37 °C (99 °F)

3. The expected effect of different factors on body temperature are:

   A. Raising air temperature: Increase

   B. Lowering air temperature: Decrease

   C. Adding clothing: Increase

   D. Exercising: Increase

This is for a logical reason, anything you do to heat it or generate heat, will increase the temperature. And anything you do to generate cold, will lower the temperature.

The effect of different factors on body temperature according to Gizmo:

   A. Raising air temperature: Increase

   B. Lowering air temperature: Decrease

   C. Click Add to a sweatshirt, hat, pants, and  parka. Then, adding clothing:

   Maintained

   D. Set the Exercise level to 70%, then exercising: Increase

When the temperature increases, it is because you are able to record the results from the software and you see temperature goes from 99 °F to 100 °F. When the temperature decreases. it is because it goes from 99 °F to 97 °F. When it is maintained, there is no change.
