Answer:
True
Explanation:
The deep parts of an ocean receive minimal or no sunlight. Hence, the survival of phototropic organisms like plants and algae is impossible or minimal here. Hence, there is a very little diversity in deep oceans. The organisms living here have to feed on dead decaying matter or on each other for survival. Mostly, the organisms living here use dead organisms as food. No other food source is available here.
The chance of getting a red flower if two pink flowered plants are crossed is 25% or ¼.
<h3>WHAT IS INCOMPLETE DOMINANCE?</h3>
Incomplete dominance is a type of inheritance in which two alleles of a gene are neither dominant or recessive, hence, a intermediate phenotype is produced.
According to this question, in snapdragons, petal color is inherited through incomplete dominance with the possible colors being red, white, and pink.
If two pink flowered plants are crossed i.e. Pp × Pp, the genotype of the offsprings that will be produced as follows:
- PP (1) - red flower
- Pp (2) - pink flower
- pp (1) - white flower
Therefore, the chance of getting a red flower if two pink flowered plants are crossed is 25% or ¼.

Eutrophication results in the death of trout and other fish as a result of asphyxiation from the lack of oxygen. Eutrophication involves the enrichment of water by nutrients salts such as phosphates, nitrates among others, that causes structural changes of the aquatic ecosystem such as; increased production of algae and aquatic plants, depletion of fish species, deterioration of water quality and other effects that impact negatively the aquatic ecosystem.
The DNA, RNA or the RNA Polymerase of the infected cell would not be virus's primary source of heritable information because it has the ability to integrate into host cell and get itself replicated, also it causes infection so multiplication becomes necessary.
Explanation:
The virus has reverse transcriptase enzyme in them which works slightly different. It transcribes RNA into DNA and eventually gets integrated into the genome of the host. It is here the DNA in the host cell is transcribed and translated. Thus it is modelled to have RNA as genetic material.
When virus infects the living cell by a process called a lytic infection, it injects its genetic material into it to get replicated and increase its number and eventually bursts the infected cell. Since a virus causes infection, it has to increase in number so it uses its own genome to get replicated.
the higher the SA:V ratio of the cell the quicker the materials can reach the center of the cell
