The pollen

Biology
1 answer:
Nana76 [90]3 years ago
4 0

Answer:

The correct answer is B. The pollen cone contains the male gametophytes.

Explanation:

The cone is the reproductive organ of bare pollinators. Cones are not flowers but transformed stems or shoots without flower petals. In cones, male and female storages sit together in a shoulder-shaped arrangement on a short leg. Both males and females grow on pine. In male cones that are similar in most conifers, pollen matures, but the male cones wither quickly after the pollen has faded away.

Why is the caloric value of some sugar alcohols less than 4 kcal/g? a. They cannot be transported into the mitochondria. b. None
avanturin [10]

Answer:

Option-C

Explanation:

The sugar alcohols are the carbohydrates which are neither considered sugars nor alcohols but they partially resemble the structure of both of these sugars and alcohol.

The sugar alcohols are naturally present in the vegetables and fruits but they are also artificially synthesised like xylitol, lactitol, mannitol and others.

They are considered the alternative from of sugar but they provide less energy as compared to carbohydrates like they provide about 0-3 kcal per gram whereas sugar provides 4 kcal per gram.

This difference is due to the reason that they are not completely absorbed by the human body and also they are incompletely metabolized therefore provide less energy.

Thus, Option-C is the correct answer.

aliya0001 [1]

Tropical rainforests is an area of vegetation comprising of predominantly trees. Trees play a major part in sustaining the environment, and hence, the destruction of trees will result in certain negative effects or impacts on the environment.

One of the effects of destroying rainforests according to the options in the question, is the reduction in the amount of water vapor. Trees in rainforests contribute to the addition of water vapor to the atmosphere via transpiration (loss of water through their stomata). Hence, destruction of tropical rain forests will reduce the amount of water vapor.
