This would be an example of:
C) an insertion mutation.

Notice how the sequence contains the same letters as before, only an A is added to the beginning. Adding extra nucleotides is an example of an insertion mutation, a type of frame-shift also, because the reading frame will be thrown off downstream.

How would homeostasis be affected if the cardiac muscle stopped contracting?
vodka [1.7K]

The heart is a muscle, therefore, if the cardiac muscles stopped contracting, the result would be the ceasing of heart function. That would lead to death, as blood wouldn't be pumped throughout the body. Homeostasis would therefore be interrupted.

What organisms save water by turning carbon dioxide into a special carbon compound before carrying out photosynthesis?
larisa [96]

The correct answer is C4 plants.  

A plant that cycles carbon dioxide into four-carbon sugar components to get into the Calvin cycle is known as a C4 plant. These plants are very effective in dry, hot climates and produce ample energy. Various foods one consumes are C4 plants like pineapple, corn, and sugar cane.

In the C4 plants, at the start carbon fixation occurs in the mesophyll cells and the Calvin cycle occurs in the bundle-sheath cells. The PEP carboxylase combines with an incoming molecule of carbon dioxide to the three carbon-molecule PEP, generating a four carbon molecule, that is, oxaloacetate.

CAPACITY..

Limiting factors determine carrying capacity. The availability of abiotic factors (such as water, oxygen, and space) and biotic factors (such as food) dictates how many organisms can live in an ecosystem. Carrying capacity is also impacted by the availability of decomposers.

BIODIVERSITY...

While food and water supply, habitat space, and competition with other species are some of the limiting factors affecting the carrying capacity of a given environment, in human populations, other variables such as sanitation, diseases, and medical care are also at play.
