Answer:
Pp, PP
Explanation:
Purple: P
White: p
Purple flowers can still carry the white flower trait, that's how their offspring gets it. Since this offspring is purple, the dominant trait is present and will always show over the recessive trait. So of you get a purple flower the possible genotypes are PP and Pp, if you have a white flower the possible genotypes are only pp. :)
Answer:
True
Explanation:
This statement is true. Medical researchers at Harvard and Stanford universities found that leading a sedentary lifestyle (sedentary meaning minimal exercise with little movement) leads to a higher risk of health complications (which can be more prevalent in older age).
This finding strongly recommends that middle-aged people should undertake some form of regular exercise so as to not fall into the category of "sedentary".
Despite their frequency in the intertidal zone, in tide pools, sea urchins can be found at many different depths and in any habitats. They can also be found in nearly any ocean temperature. Sea urchins inhabit the polar seas as well as the warm tropics.
