Answer:
provirus
Explanation:
it is the only virus that have the mixture of t cell DNA
Explanation:
The structure of the leaf is adapted for gas exchange. The cells in the spongy mesophyll (lower layer) are loosely packed, and covered by a thin film of water. There are tiny pores, called stomata , in the surface of the leaf. Most of these are in the lower epidermis, away from the brightest sunlight.
The stomata control gas exchange in the leaf. Each stoma can be open or closed, depending on how turgid its guard cells are.
In the light, the guard cells absorb water by osmosis, become turgid and the stoma opens.
In the dark, the guard cells lose water, become flaccid and the stoma closes.
Diffusion of carbon dioxide, oxygen and water vapour into (or out of) the leaf is greatest when the stomata are open.
Answer:
D. Habitats are opened up for less competitive species.
Explanation:
it is generally known and approved that any increase in the complexity of habitat will cause increase in the disturbance in community diversity.after the conduction of many studies, it was conducted that the the species show variation in their abundance and distribution to habitat complexity.
The weight is 834.
To find out the mass, we have to divide by 9.8 because we multiplied x (the mass = x) by 9.8 to get to 834.
834/9.8= 85.1 KG is the mass.
