Answer:
1)The leaves and stems of many desert plants have a thick, waxy covering. This waxy substance does not cover the stomata, but it covers most of the leaves, keeping the plants cooler and reducing evaporative loss. Small leaves on desert plants also help reduce moisture loss during transpiration.
Answer:
B
Explanation:
unusually weak magnetic fields on the sun paired with reduced solar activity cause sunspots to disappear.
Answer:
10g
Explanation:
A cross between genotype AA BB is crossed with a plant with genotype aa bb will produce
Parent genotype:AABB x aabb
Gametes: AB x ab
F1 generation - AaBb
Since an uppercase letter contributes 4 g to weight and each allele represented by a lowercase letter contributes 1 g to weight.
Thus, 4+1 + 4 + 1 = 10g
Answer:
Bacteriostatic
Explanation:
The antibiotics are the compounds which are used to treat the bacteria and are of two types: the bacteriostatic and bactericidal.
The bacteriostatic antibiotics are the antibiotics that do not kill the cells but they stop the reproduction of the bacteria and keep them in their stationary phase.
In the given question, since the antibiotic does not kill the cell but stops the doubling that is reproduction therefore the antibiotic is bacteriostatic.
Thus, bacteriostatic is correct.
Answer: Mars receives more insolation than Saturn.
Explanation:
Insolation is defined as the exposure to the Sun's rays.
Mars is the 4th planet in Our solar system and is near to the Sun.
Saturn is the 6th-planet in Our solar system and is far from the Sun.
Insolation is directly proportional to the planet's distance from the Sun.
So, the exposure of Sun's rays is more to the planet which lie close to the Sun.
As, Mars is close to the sun than Saturn. Hence, it will receive more insolation than Saturn.
