Joey eats strawberries for lunch. Explain how homeostasis is maintained in the endocrine systems once the fruit has entered Joey’s body.

Answers

Answer:

Explanations:

Homeostasis can be defined as the phenomenon whereby there is balance or stability within the internal and external environment of a cell or the body. The internal environment of the organism is kept constant during homeostasis. During this process there is adjustments in the

internal environment Because there is always change in the conditions inside and outside the cell. When the system of the body is able to adjust itself it's reffered to as homeostatic regulation.

The endocrine system which contains glands that is responsible for the secretion of hormones into the bloodstream play also vital part during Homeostasis, This is because hormones which are the chemical messaged effect some change cells in another part of the body. The endocrine system is responsible for the regulations of

metabolism as well as the development of some body cells and systems via feedback mechanisms, hormones such as

Thyrotropin-Releasing Hormone during Homeostasis. Therefore as Joey eats strawberries for lunch the hormones makes adjustment of muscle metabolism and also regulate fluid and ion concentration in the system or body

A group with 30 DD parrots, 40 Dd parrots, and 30 dd parrots is most likely in Hardy-Weinberg equilibrium.

What do you mean by Hardy-Weinberg equilibrium?

The Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation.

The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.

For populations in the Hardy-Weinberg equilibrium, the equation connects allele frequencies to genotype frequencies. This equation allows us to compare a population's genetic structure in reality over time to the expected genetic structure.

Some laboratory mice are spotted, due to a dominant gene. Solid color is recessive. A solid color female mouse is mated to a spotted male. Both parents are homozygous. What percentage of mice should be found in the litter?

Answers

Answer: percentage of mice that will be spotted is 100%, and 0% chance of being solid colored.

Explanation:  First, homozygous means each parent have matching chromosomes (Like XX, instead of Xx)

Lets make a punnet square and show the data. We will use 'S' for spotted and 's' for solid

The punnet square shows that the percentage of mice that will be spotted is 100%, and 0% chance of being solid colored.

Hope this helps :)

The percentage of mice that will be spot-ted is 100%, and 0% chance of being solid colored.

Calculation of the percentage:

In the first time, h-o-m-o-z-y-g-o-u-s means each & every parent should have matching chromosomes (Like X-X, instead of X-x)

So based on this, we can say that The percentage of mice that will be spot-ted is 100%, and 0% chance of being solid colored.

in this way, the percentage is determined.

Answers

Answer:

The simulation only shows how a population can change overtime in response to the changes in the environment. During the industrial revolution, one particular phenotype of moths had an advantage over the other and hence, was subjected to natural selection. What this simulation does not tell us is the causality and correlation aspect of the change that occurs in the moths. Correlation does not equal causation, and the simulation does not shed any light on these variables in this case.

Which feature separates watersheds?
A.) basins
B.)bays
C.)ridges
D. )rivers

Answers

Answer:

c

Explanation:

C.) Ridges are the feature that separates watersheds.

What is watershed ?

A watershed is a region or area of land that collects and drains water into a particular river, stream, or other body of water.

Ridges or high points of land are critical in separating watersheds because they provide the boundary or border between two adjacent watersheds. When rain falls or snow melts, the water will flow downhill towards the closest body of water.

However, if that body of water is separated from another by a ridge, the water will flow down opposite sides of the ridge, into different watersheds.

Ridges are created by geologic processes such as tectonic uplift or erosion, and can vary in size and height. In some cases, a single ridge can divide a large drainage basin into two or more smaller ones, each with its own unique set of characteristics and ecosystems.

The boundary or border of a watershed is formed by a ridge or high point of land that separates one watershed from another. Water that falls on one side of the ridge flows into one watershed, while water that falls on the other side of the ridge flows into a different watershed.
