D is the answer. A gene is a part of a chromosome.
Answer:
temporal reproductive isolation
Explanation:
The correct answer would be temporal reproductive isolation.
<u>Reproductive isolation</u> generally refers to series of biological mechanisms or processes that prevent members of different species from mating/fertilization or prevent the product of their mating to be invalid.
Some reproductive isolation processes prevent members of different species from mating or prevent fertilization as a result of mating. These processes are known as pre-zygotic reproductive isolation mechanisms.
Some other processes ensure that the product of fertilization (when it occurs) is invalid. These are known as post-zygotic isolation mechanisms.
<em>A good example of the pre-zygotic reproductive isolation process is </em><em>when closely related by different species bloom at different times</em><em>. This will prevent mating or cross-pollination to happen between the different species. This is known as temporal reproductive isolation.</em>
Approximately 190 would have red, terminal flowers.
<h3>What is True breeding?</h3>
Organisms with homozygous genes are referred to as true breeders in genetics. This indicates that both alleles are identical, making PP or TT preferable to Pp or Tt. All offspring produced from the union of true breeding organisms will share the same phenotypic as their parents.
<h3>What is true breeding in Punnett Square?</h3>
Both alleles of a gene are the same in genuine breeding strains. Due to the presence of just one type of allele, crossing two plants from the same strain will result in offspring with the same genotype and phenotype as their parents.

Answer:
None of the options provided is correct but some are close
Explanation:
One of the ways in which a cell maintain homeostasis is by regulating what goes in and out of the cell through the cell membrane (which is a semi-permeable barrier). The amount of water is highly regulated by the cell in this case so as to regulate osmosis (movement of water molecules from a region of higher concentration to a region of lower concentration). Other substances regulated are oxygen and carbon dioxide.
NOTE: The cell <u>does not create water molecules neither does it use carbon dioxide to maintain homeostasis</u>, it rather regulates these two compounds.
