Xylem is the answer......
Answer:
THE ANSWER IS D!!!!!!!!!!!
Explanation:
Answer:
The correct answer is A it transport the food generated by photosynthesis.
Explanation:
Both xylem and phloem are the examples of vascular tissue present in plants.xylem helps in the transport of water from root to different parts of the plants.
Whereas phloem helps in the transport of photo synthate from mesophyll tissue to sieve element companion cell complex.The transport of photosynthate to different non photo sythetic parts of a plant involves both symplastic and appoplastic pathway.
Symplastic pathway is a passive process depending on the pressure gradient for the transport of solutes through the plasmodesmata which connect 2 adjacent plant cells.
Appoplastic pathway is an active transport process occuring against the concentration gradient which does not involve plasmodesmata.
Answer:
<em>If the Tamiflu-resistance gene involves a cost, it will experience directional selection leading to reduction in its frequency.</em>
Explanation:
The new virus will be resistant to Tamiflu. The Tamiflu resistance gene will become common in the environment due to directional selection. Directional selection can be described as a condition in which one phenotype is favoured such that the phenotype becomes abundant in an area and hence the allele frequency of the area changes. This occurs because that phenotype is better adapted to survive in an environment.
Answer: Oxygen consumption within the mitochondria will decrease further
Explanation:
If the NDU gene is amplified inside cells leading to overexpression of the protein, the event that is likely to occur under hypoxic conditions is Oxygen consumption within the mitochondria will decrease further
