What is an advantage of the mutualistic relationship between angiosperms and animals?
S_A_V [24]

Answer:

Refer below.

Explanation:

It is a beneficial species types association. The two life forms in the relationship profit by it. This typically happens in light of the fact that every living being needs something different has, so they can exchange.

Flowers that require fertilization are in a mutualistic relationship with the insects that fertilize them. The bloom gives nectar to the bugs to eat, and the creepy crawlies fertilize the blossoms.

Which of the following accurately pairs the phase of the cell cycle with its primary purpose?
babunello [35]
According to a source, the answer is <u>A. M phase–Cell growth before DNA replication.</u><span>

Mitosis is the cell division that happens in all cells in the human body except sperm and egg cells. They produce diploid cells. Meiosis on the other hand is responsible for the cell division of the gametes, spermatogenesis (sperm cells) and oogenesis (egg cells), such haploid cells. Take for instance your integumentary system, layer of the skin in which your stratum basale always produces new epithelial cells (via mitosis) to take over until the outer layer, called stratum corneum (a continous replaced dead cells in this layer). </span>

Angiosperms do not need water for fertilization. Why? (3 points) Group of answer choices Flagellated sperm travel to the ovary i
astraxan [27]

Answer:

A pollen tube grows from the pollen grain into the ovary

Explanation:

Water is needed for fertilization in several plant groups because the sperm needs to swim to meet the non-motile eggs of the female organs.

<em>However in angiosperms, the pollen germinates and a structure known as pollen tube which contains the male gametophyte (sperm) grows into the ovary where the ovule is located and the male gametophyte is deposited in the ovule to initiate the fertilization process.</em>

<em>Hence, water is really not necessary for fertilization in the angiosperms.</em>
