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 .
Answer:
They contain symbiotic rhizobia bacteria within nodules in their root systems, producing nitrogen compounds that help the plant to grow and compete with other plants. When the plant dies, the fixed nitrogen is released, making it available to other plants; this helps to fertilize the soil
Answer:
0.5
Explanation:
Given, gene O results in production of pigment.
OO, Oo = Orange
oo = white
If Oo X oo :
O o
o Oo oo
o Oo oo
Half of the progeny will have Oo genotype so they will be heterozygous and will have orange fur. Other half will have oo genotype so they will be homozygous recessive and will have white fur. So the odds of having a white tiger cub is 0.5.
