The transmission of heat requiring the movement of a liquid or a gas is Convection.
Convection: the heat transfer due to bulk movement of molecules.
Hope this helped :)
Have a great day
Explanation:
The two main parts of a triglyceride lipid are glycerol and fatty acids.
The option D is correct :The gametophytes of seed plants are never exposed to the external environment. Unlike spores, The gametophyte in seed plants is often tiny and is kept in the tissues of the sporophyte. The integument refers to the layers of sporophyte tissue that encircle the megasporangium.
seeds carry food reserves that can be used to support a young plant. While spores are distributed by the wind, seeds can be spread by animals. While spores only live a few days, seeds can slumber for weeks or even years. Seeds contain a supply of food in storage, in contrast to spores. If the conditions are right, seeds that have been transported far from the parent sporophyte may germinate and rely on stored nourishment to develop into seedlings. Spores and seeds vary primarily in that seeds have stored nourishment in their endosperm, which allows them to germinate in adverse conditions whereas spores do not, making them more dependent on good conditions for germination.

Explanation:
This is because Prophase is marks the beginning of mitosis, and it is the process where replicated genetic contents are separated into daughter cells. During prophase, ttgere is condensation of chromatin. The chromatin coils and it become compact, which lead to the formation o chromosomes that are visible. The sister chromatids are joined together at the centromere. The mitotic spindle begins to form. The mitotic spindle is consist of long proteins called microtubules that firms at opposite end. The spindle separate the two sister chromatids.
The total charge is zero.
