Answer:
Both genetic and environmental factors play a role in promoting various trait. The growth of a plant will first of all depend on the alleles which it carries. If the plant has alleles which promote plant growth then the plant will grow more than the plants not having those alleles.
Apart from the genes, the environment also has a role to play in the growth of a plant. The amount of sunlight, the nutrition, temperature, pH are all environmental factors which will either enhance the plant growth or will suppress it.
Answer:
TGCAAATCATT
Explanation:
Because adenine always pairs with guanine and cytosine always pairs with guanine, just pair the A's in the sequence with G's for guanine, and so on so forth.
Answer:
The correct answer would be D.Alveolar sacs are surrounded by thin capillaries where gases can be exchanged.
Alveoli are tiny sacs which form the site of gas exchange in the lungs.
The features of alveoli which help in gas exchange are:
- They increase the surface area in the lungs thus, more space is available for gas exchange.
- They have very thin walls, as thin as the thickness of a single cell only.
- They are surrounded by a bunch of thin capillaries which exchange gases with alveoli.
Answer;
-Water will flow more freely across the semi-permeable membrane
Explanation;
-The movement of water from a region of lower solute concentration to a region of higher solute concentration is called osmosis. It is the net movement of water molecules through a semi- permeable membrane into a region of higher solute concentration (lower solvent concentration).
-Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane.
