Answer:
The function of the pollen tube is to lead sperm cells into the ovary.
Explanation:
In angiosperms, the pollen tube is a structure formed when the pollen grain comes into contact with the stigma and germinates, producing a tubal extension that is related to the embryonic sac where the female gametophyte is found.
The function of the pollen tube is to conduct the male gametophyte —which is found in the pollen— to the embryonic sac, in order to come into contact with the oosphere and produce fertilization.
The other options are not correct because the pollen tube:
- <em>Do </em><u><em>not create more pollen</em></u><em>.
</em>
- <em>Do </em><u><em>not create more male spermatophytes</em></u><em>.
</em>
- <u><em>Does not lead the eggs to the male spermatophytes</em></u><em>.</em>
A priority goal for the client with CGD is to manage the s/s of the disease process so as to maintain the client's functional ability. Chest pain is not a typical sign. The carbon dioxide concentration in the blood is increased to an abnormal level; it would not be a goal to increase the level further. Preventing infection would be a goal of care for the client.
Answer:
Translation.
Explanation:
The mRNA formed in the transcription process is transported out of the nucleus, then goes into the cytoplasm, and then to the ribosome. The ribosome is called the cell's protein synthesis factory.
In the ribosome, it directs protein synthesis. Messenger RNA is not directly involved in protein synthesis. Transfer RNA (tRNA) is required for this. The process by which mRNA leads to protein synthesis with the assistance of tRNA is called translation.
So we can say that the transfer RNA (tRNA) is used in the translation process.
Answer:
a mucus or a gelatinous sheath
Explanation:
Most species of cyanobacteria are enclosed in a gelatinous sheath which is made up of proteins.
