Answer:
d. Preload increases.
Explanation:
Preload is affected by the rate of venous return and the venous blood pressure , which are affected by the volume of circulating blood and venous tone .
The preload is related to ventricular end - diastolic volume ,
The higher end - diastolic volume have a higher preload .
<u>Preload is approximated via echocardiographic measurement end diastolic volume or EDV.
</u>
Preload is increased by exercising , or increase in blood pressure and neuroendocrine excitement .

Since the corals lack the zooxanthella that are found in tropical coral reefs because the zooxanthella require sunlight and there is no sunlight, the corals are built upwards instead of across. The polyps build the coral this way because they are filter feeders. The correct answer is C, filter feeders.
A. all yellow
they will look all yellow but all will be heterozygous
Energy from the sun reaches Earth by way of radiation.
The sun cannot conduct heat to the Earth directly because the two bodies are not in contact with each other. Convection is also impossible, as no medium connects the two bodies to facilitate heat flow. Instead, the sun radiates much of its energy as light of various wavelengths. Some of this radiated light is in the infrared part of the spectrum and reaches Earth as heat.
Light in the visible part of the spectrum also has the effect of warming the Earth. It does this by penetrating the atmosphere and being absorbed by the land and water. Once the Earth has absorbed all of the energy it can hold, it begins to radiate energy back toward space. This terrestrial radiation is primarily in the infrared band of the spectrum, which is absorbed by aerosols in the atmosphere. These greenhouse gases trap heat and store up the surplus energy of the Earth's allotment of solar radiation. Eventually, even the atmosphere reaches thermal saturation and radiates waste energy back out into space.
I hope this helps :)
