a the adaptation that made possible the colonization of dry land environments
by seed plants is most likely the result of the evolution of pollen.</span>
The main advantage of seed plants
(Gymnosperms and Angiosperms) is the evolution of the seed which, unlike
spore-producing plants, was not limited to wet environments. Pollen grains are
male gametophytes (sperm) which are protected from desiccation and can reach
the female organs without dependence on water. The sperm is transferred from
the pollen through the pollen tube: an extension of a cell within the pollen
grain. The process is called pollination.
When parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus. The distance between the principal focus and the centre of the lens is called the focal length.
Answer:
regulates other proteins
Explanation:
Ubiquitin is a small protein that is found in almost all cellular tissues in humans and other eukaryotic organisms, which helps to regulate the processes of other proteins in the body.
hope this helps, pls mark brainliest :D
