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 .
I think this depends on you because it your choice for yourself but I'll just state some information or facts about this career.
- The field is a specialization in biomedical engineering that can take four to eight years to master.
- Genetic engineering has been applied in numerous fields including research, medicine, industrial biotechnology and agriculture. In research GMOs are used to study gene function and expression through loss of function, gain of function, tracking and expression experiments.
- Success rates are incredibly low; on average, less than 10% of embryos survive to birth and a smaller percentage of those born survive to adulthood.
- The field of genetics allows you to work in medical as well as scientific research.
- To become a genetic engineering research scientist, you need a doctoral degree in a biological science.
- Genetic engineers can earn anywhere from $44,320 to $139,440 a year.
Hope this helps and if you could mark me as brainliest. Thanks!

Answer:
Reproductive isolation can occur when individuals or the populations exhibit differences in the timing of various activities like mating and so on .
During high-intensity exercise, muscles primarily get their energy from the carbohydrates we intake. These biomolecules are what the body uses to store and produce energy for each activity we do. These substances are very important to be part of our diet.
