There are three and they are the Atmosphere, lithosphere, and hydrosphere
Answer:
Facilitated diffusion require no energy and travels down the gradient of concentration. On the other hand, active transport takes energy and travels up the gradient of concentration.
Hope this helps! Have a great day!!
Answer:
12-day litter weight is a trait that has an important genetic influence and therefore also a high response to selection
Explanation:
Heritability is a statistical measure of how much of the variation in a given trait can be attributed to genetic differences and how much of trait variation is due to environmental factors. A heritability value close to 1 indicates that almost all of the variability is due to genetic factors, while being poorly influenced by environmental factors. In this case, 12-day litter weight is a trait that exhibits an important genetic component (i.e., a high heritability value), thereby the correlation between parent and offspring will be high and lines selected for this trait will show a high response to selection.
It is <u>TRUE</u> that multiple polypeptides joined together represents the tertiary level of protein organization.
Before a cell divides DNA replicates itself. hope this helps!
