Answer:
Four.
Explanation:
Initially four haploid spores are produced by meiosis. We know that during meiosis pairing between homologous chromosomes occurs and this created genetic difference between the divided cells. Exchange of genetic material doesn't occur during mitosis so mitotically divided cells are similar. Thus when spores divide by mitosis and become eight in number, here will be no new genetic difference.
The complete sentence will be -
A nucleus within an ascus undergoes meiosis, producing four haploid spores, which then undergo mitosis, producing eight haploid ascospores. These haploid ascospores contain a maximum of four different genetic types.
Widened margins does not occur at the continental margin
Answer:
The cell membrane is semi-permeable. It allows some molecules to enter easily inside the cell whereas some molecules are blocked from entering the cell.
Small, polar molecules and hydrophobic molecules enter easily through the cell membrane. But large molecules and ions cannot easily move inside the cell membrane.
A hydrophilic substance like the substance L mentioned in the question enters the cell membrane through the help of carrier proteins. The substance attached to the large protein might enter through active or passive diffusion but it can only enter the cell by attaching to carrier proteins.
False, the angle is consistently the same, yet the placement of the Earth at this angle directed at the sun is what allows the Earth to have seasons (Spring, Summer, ...) So the answer is false.
<h2>The answer is True.</h2>
Explanation:
Broccoli, kale, brussels sprouts, cauliflower, and cabbage all belong to the species, Brassica Oleracea.
Kale was developed when the plant's leaves get enlarged.
Cabbage was developed when a terminal bud which is large in size is selected.
Brussels sprouts are developed by the buds which are grown with the plant stem.
Brocoli was developed when clusters of large flower are selected.
