Answer:
<em>The correct option is B) 5-10%</em>
Explanation:
We have seen and depicted various scenarios where we see how different changes arise and dominate the world. Social scientists suggest that as low as 5-10% people of a population are enough to bring about a change because people tend to copy what others are doing. Same goes for countries of the world. Each new popular technique which is learnt by one country tends to become popular and learnt by other countries. For example, the usage of a social app starts with a few members of a population using it and with time it becomes popular in the whole world.

Answer:
The cycle of energy is based on the flow of energy through different trophic levels in an ecosystem. ... At the first trophic level, primary producers use solar energy to produce organic material through photosynthesis. The herbivores at the second trophic level, use the plants as food which gives them energy.
Explanation:
Answer:
The correct answer would be "The female cone releases its seeds and new sporophytes grow".
Conifers are sporophytes with two types of cones; pollen cones and ovulate cone.
The pollen cones are smaller in size and produce microspores which would develop into the pollen grains.
The ovulate cones are larger in size which produce megaspores which would develop into ovule.
The two gametes fertilized to produce a diploid zygote which develops into the embryo.
The fertilization takes place in the ovule and thus, embryo or seed is developed in the female cone.
The female cone then releases its seed which grows into a new sporophyte.
Answer:
The gene frequency for the albino allele is 16%.
Explanation:
Given that in a population with 100 rabbits there are 16 that are albino, with two recessive genes for albinism, to determine, in this population, what is the gene frequency for the albino allele, the following calculation must be performed:
16/100 = X
0.16 = X
1 = 100
0.16 = X
0.16 x 100 = X
16 = X
Therefore, the gene frequency for the albino allele is 16%.
