Answer:
vestigial structure that is C
Plants have cell walls, so cytokinesis cannot go on with a cleavage furrow, but instead, a cell plate forms across the cell in the location of the metaphase plate.
There is no distinct groove along the cell plate as the cell divides because of the rigid nature of the cell plate or new cell wall.
A plant cell divides differently from an animal cell which forms a clear cleavage furrow because it only has a flexible cell membrane and not a rigid cell wall like plants.
The cell plate in plant cells is formed by membrane bound vesicles which migrate to the center of the cell where the metaphase plate used to be and fuse together to form a cell plate.
Answer:
The correct answer will be option - D.
Explanation:
Slime moulds are the fungus-like protists which bear a structure called sporangium which produces spores. The sporangium is produced in fungi as well due to which these protists are called fungus-like. Although both produce sporangium but they are not closely related, rather they are distantly related organisms.
The appearance of a sporangium in both indicates that they had faced the same conditions due to which they both showed the same adaptation by producing the same structures performing the same function. In evolutionary terms, this is an example of convergent evolution.
Thus, option D is the correct answer.

Step by steps explanation
Answer:
This happens because pollination processes are increased over time, with time prevailing in the environment and in the air, and people with time hypersensitivity are more widespread over time.
Explanation:
Many scientists investigate these situations and mainly affect people at the respiratory level since pollen is inhaled, generating possible edema and bronchoconstrictions.
Other researchers also relate it to environmental pollution since it increases or extends the heat periods throughout the year, so this event is aggravated in patients with asthma and allergies, since the pollution has a direct effect on the airways.
Many particles suspended in the air by pollination and contamination are the cause of inflammation and bronchial hyperreactivity in patients with chronic pathologies. Substances like nitrogen oxides, sulfur dioxide, carbon monoxide and ozone promote the production of symptoms and exacerbations in children with asthma.
