What could happen to the reproductive process of mosses during a drought? The flagellated sperm would not be able to swim to the

eggs for fertilization. The flagellated sperm and eggs would go dormant until water was available. Mitosis in the sporophyte would cease and the reproductive cycle would stop. Meiosis in the sporophyte would cease and the reproductive cycle would stop.

The answer is <span>The flagellated sperm would not be able to swim to the eggs for fertilization.

</span><span>Their life cycle of mosses has alternation of generation - a haploid gametophyte and a diploid sporophyte. Gametophyte produces haploid gametes which fuse to form a diploid zygote. The zygote grows into diploid sporophyte which produces haploid spores. The spores grow into gametophyte and the cycle begins again.
</span>Mosses require water for reproduction. Before fertilization, the sperm swims to an egg through the water. Therefore, mosses require water for successful fertilization. In drought periods, without water, the sperm cell could not swim to the egg cell.

The fertilization in<br> frog<br> is called external fertilization.Why?​
spayn [35]
Answer:

External fertilization usually occurs in aquatic environments where both eggs and sperm are released into the water Most external fertilization happens during the process of spawning where one or several females release their eggs and the male(s) release sperm in the same area, at the same time.
Typically, frogs lay eggs. This process usually occurs through external fertilization, where the female releases her eggs from her body into water. Then, the male releases his sperm to fertilize them In this case, the eggs are fertilized inside the female's body before they are released.

lana [24]

Answer:

0.04 for 6 legs starfish and 0.96 for 5 legs starfish.

Explanation:

The allele frequency for the 6 legs starfish is 0.04 whereas, the allele frequency for the 5 legs starfish is 0.96 because there is only one 6 legs starfish in the given population as compared to 5 legs starfish. The low population of 6 legs starfish is due to the presence of recessive allele while on the other hand, higher population of 5 legs starfish is due to the presence of dominant allele. The allele frequencies for both population is done by dividing the allele of interest by total number of alleles present in the population.

In an animal cell, which two cell structures do newly-synthesised enzymes have to pass through to reach the external environment
ss7ja [257]

Answer:

Ribosomes, Cell membrane

Explanation:

Ribosomes can be described as structures which are involved in the production of proteins. Ribosomes are hence known to be the protein manufacturing units of a cell. As enzymes are also proteins,they will be synthesized in the ribosomes.

Cell membrane can be described as the membrane which is present outside the cell or which separates the cell from the external environment.

For an enzyme to pass through the external environment, it will have to pass through the ribosomes and the cell membrane.
