1.The process of leaf color change. Leaves change color during the autumn because the amounts of pigments change as the leaves prepare to fall from trees. All leaves gradually lose chlorophyll during the growing season, and this loss accelerates before leaf fall.
2.The leaves in hot or dry environments may be adapted to reduce transpiration. For example, their stomata may be open at night and close midday. This is the reverse of what usually happens, and it means that the stomata are closet when the rate of transpiration would be greatest.
Answer:
Explained below:
Explanation:
Density-dependent factors are biological factors adopted by the population as a resource. The things can be like shelter, food, or different poor resources. Density-dependent factors affect fitful variations in the population as its density fluctuations. If the population is small, these portions typically support improved rates of birth and lower will be the death rates, empowering the population to increase and when the population is big and thick, these factors display that the birth rate is decreased and death rate became higher.
Answer:
The tall parent was heterozygous
Explanation:
If tall height is dominant to short height the only genotype possible for short height is hh, while there are two possible genotypes for tall height, Hh and HH. When HH is crossed with hh all the offspring are Hh, but if Hh is crossed with hh, a quarter of the offspring is HH, a quarter is hh and half is Hh. If the tall pea plants were HH there would only be tall offspring, but because there are some short offspring we know that the tall pea plants must have a genotype of Hh.
Answer:
This voice box occurs in all amphibians but is anatomically most complex in frogs. The larynx exits into the trachea; the latter bifurcates into the bronchi and then into the lungs. The glottis then opens, and elastic recoil of the lungs forces the pulmonary air out and over the new air in the buccopharyngeal pocket.
