When molecules uses energy for transportation across the cell, then it is known as "Active Transport"
So, option B is your answer.
Hope this helps!
What area of a cell is the location of rRNA synthesis and is also in charge of ribosomal subunit assemblage?
What is rRNA?
Ribosomal RNA (rRNA), a molecule in cells that is transferred to the cytoplasm and is a component of the protein-producing organelle known as a ribosome, aids in the conversion of messenger RNA (mRNA) into protein. rRNA, mRNA, and transfer RNA are the three main forms of RNA found in cells (tRNA).
Nucleolus area of a cell is the location of rRNA synthesis and is also in charge of ribosomal subunit assemblage.

Answer:
B. Fossil fuels are nonrenewable and may cause pollution.
Explanation:
Fossil fuels are nonrenewable, meaning that they cannot be replenished sustainably. So, eventually, we will run out of them because they cannot be renewed.
Another disadvantage of fossil fuels is that they cause pollution. For example, the gasoline that is used by cars creates significant amounts of pollution every year.
Pollution is created by cars, factories, homes, and everything else that uses fossil fuels.
So, the correct answer is B, fossil fuels are nonrenewable and may cause pollution
Answer:
a. purple allele (C) = 0.609, pink allele (c) = 0.391
b. purple homozygotes = 371, pink homozygotes = 153, heterozygotes = 476
Explanation:
Given -
Purple flowers - 847
Pink flowers - 153
The frequency of recessive genotype i.e

Frequency of recessive allele i.e q is equal to

As per hardy Weinberg's first equilibrium equation -

Frequency of purple homozygous species

Number of purple homozygous species 
Number of pink homozygous species 
Heterozygous species is equal to

D) a change in protein synthesis
