People believed that zebras were white animals with black stripes, since some zebras have white underbellies. Embryological evidence, however, shows that the animal's background color is black and the white stripes and bellies are additions.
Answer:asteroids and comets
Explanation:
Answer:
True
Explanation:
<em>Aristotle initially thought that life arose spontaneously and he backed this up by showing that a lump of meat left uncovered in a glass jar spontaneously produced maggots.</em>
The spontaneous generation theory was later disproved by another scientist, Francesco Redi. He showed that a covered jar containing a lump of meat will not spontaneously produce maggots unless flies are allowed to perch and lay their eggs on the meat. The eggs of the flies give rise to the maggots and not the meat.
<u>It thus showed that new life does not arise spontaneously but rather through development and reproduction.</u>
<h2>Functions of plasmodesmata</h2>
Explanation:
- They allow the movement of cells to cells for cytoplasmic connection between different cells
- Plant cells, encompassed as they are by cell dividers, don't get in touch with each other through wide stretches of plasma film the manner in which creature cells can. Be that as it may, they do have particular intersections called plasmodesmata (solitary, plasmodesma), places where a gap is punched in the phone divider to permit direct cytoplasmic trade between two cells.
- Plasmodesmata are fixed with plasma film that is consistent with the layers of the two cells. Each plasmodesma has a string of cytoplasm stretching out through it, containing a much more slender string of endoplasmic reticulum.
- Particles beneath a specific size (the size rejection limit) move unreservedly through the plasmodesmal channel by latent dissemination. The size avoidance limit changes among plants, and even among cell types inside a plant. Plasmodesmata may specifically enlarge (extend) to permit the section of certain huge atoms, for example, proteins, in spite of the fact that this procedure is inadequately comprehended.
