Answer:
The cell must replicated DNA because when the cell divides, the daughter cells must have identical copies of DNA. DNA replication occurs in the S phase during interphase of the cell cycle.
The cerebrum is a large part of the brain containing the cerebral cortex it lies either in front or on top of the brainstem
Answer:
The correct answer here is D) None of the above
Explanation:
Lactose intolerance and sucrose intolerance in themselves are not practices but side effects of practices that affect health concerns.
For instance, research shows that cultures with a long history of dairy farming and milk drinking or at least a history of drinking milk have a much higher likelihood to be <u>lactose tolerant</u> than those who don't. And when they can tolerate lactose their bodies take note of this and records the same in their genetic databank.

Answer:
Option-D
Explanation:
Casparian strips are the strips or band composed of a hydrophobic substance called the suberin which forms the ring-like structure in the endodermis of the vascular plants.
The Casparian strips are present around the vascular bundles in the endodermis to allow the uptake of the selective nutrients as the substance has to pass through the cell membrane before it enters the centre of the root or stele or vascular bundles.
The Casparian strips allow the movement of a substance through symplast mode only, therefore, is ensures the substance to pass through the cell membrane.
Thus, Option-D is correct.
So that there is more gene variation. Let's say if they all had the same genes, one specific disease would be fatal for the species' existence since they would all be the same. The diverse gene pool allows species to develop different characteristics that can help them defend against disease
