What happens when the most<br> limiting factor in an ecosystem is<br> removed?
Anvisha [2.4K]
The answer is A, population growth increases .

—Explanation—
•] The definition of limiting factor; anything that constrains a population's size and slows or stops it from growing.
•]Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources.
•] So if the limiting factor is removed then the population begins to expand due to not having a factor that limits each species quantity.

One role of the pancreas is to help regulate blood glucose levels. Two types of cells in the pancreas, beta and alpha, serve as
solniwko [45]

1. Regulation of glucose blood levels is an example of negative feedback mechanism.

Negative feedback mechanism is a control mechanism involved in homeostasis maintain, in this case maintenance of glucose blood levels in normal range.

Negative feedback mechanism contains sensory system that detects the changes, control system that responds to change and activates mechanisms of effector system that reverse the changes in order to restore conditions to their normal levels.

• Pancreatic cells-sensors

• Insulin-control system

• Body cells- effector cells

2. Blood glucose levels change throughout the day because of the food consumption, but in healthy individuals levels of glucose are successfully regulated via the mechanism of hormones such as insulin and glucagon in a process called glucose blood regulation.

This tight regulation of pancreatic hormones is referred to as glucose homeostasis. Insulin lowers blood sugar and glucagon raises it.

3. If the beta cells are destroyed by an autoimmune disease (immune system attacks its own cells), there would be no insulin release, and consequently, the glucose blood levels would be increased.

Diabetes type I is a metabolic disorder caused by the destruction of insulin-producing pancreatic beta cells.

e-lub [12.9K]

Answer:

The correct answer is fungi.

Explanation:

Fungi are the eukaryotic organism but they can be present in unicellular and multicellular form. They are different from plant, animals, and bacteria. They are heterotrophic organisms and do not conduct photosynthesis. Their cell wall is made up of chitin.  

Most of the fungi are saprophytes which means they take their nutrition from the dead and decaying organism. So fungi play an important role in clearing the waste organic material from the environment so they help in bioremediation. All members of fungi comes under a separate kingdom fungi.

In hamsters, we can examine the genes for coat color and eye color which are linked:B = brown coat, b = white coat, G = green ey
Inessa [10]

Answer:

10.2 cM

Explanation:

Given,

pure breeding parent 1 : BBgg = brown coat and pink eyes

pure breeding parent 2 : bbGG = white coat and green eyes

BBGG X bbgg = F1 = BbGg ( All are brown with green eyes )

When F1 progeny is test crossed with white coat and pink eyes hamster:

BbGg X BbGg = F2 =

brown, pink eyes = 99 = parental

white, green eyes = 103 = parental

brown, green eyes = 12 = recombinant

white, pink eyes = 11 = recombinant

Recombination frequency =

(total number of recombinants / total progeny ) * 100

= [( 11 + 12 ) / ( 99 + 103 + 12 + 11 )] * 100 = (23/225)*100 = 0.102 * 100 = 10.2 %

1 % recombination frequency = 1 cM distance between genes

Hence, the distance between B and G gene is 10.2 cM
