The mean weight of pumpkins in a pumpkin patch is 10 lbs. From this population a group of pumpkins, all weighing 15 lbs, were se

lected for breeding purposes. In the resulting offspring, it was noted that the average pumpkin weight was 12 lbs. What is the narrow-sense heritability of pumpkin weight in this population

Answer:

0.4

Explanation:

Narrow sense heritability is a form of heritability (the other one is broad sense) that is used to describe the percentage of trait variance that is caused as a result of additive genetic factors. It is represented as h² = Va / Vp

Where Va = additive genetic variance

Vp = phenotypic variance

In this case, to get the narrow-sense heritability of pumpkin weight in this population

We have the following

mean weight of original pumpkin patch = 10lbs

weight of a group of original pumpkin = 15lbs

the average weight of offspring pumpkin = 12lbs

Hence we have h² = Va / Vp

= (12 - 10) ÷ (15 ÷ 10)

= 0.4

Answer:

The correct answer will be option-D

Explanation:

The process of photosynthesis release oxygen from the plant which is used by the organism on earth during cellular respiration.

The oxygen released by the plants is formed through the splitting of water molecules as a result of the transfer of electrons through the electron transport chain in the thylakoid membrane during the light-dependent reaction.

Since the released oxygen is the result of the light-dependent reaction and not the light-independent reaction or Calvin cycle where heavy oxygen isotope is utilized in the cycle.

Thus, option-D is the correct answer.

Answer:

lose more heat to the environment in cold environments

Explanation:

This is because as an animal have large surface area, it is exposed largely and prone to loss of heat. The larger the size of an animal, the larger the surface area and volume. It's surface area expose the tendency for the animal to sweat alot , through sweating heat is loss to the environment. In cold environment, the animal try to maintain internal homeostasis and through this heat is generated and loss to the environment.
