houses have been built around a small retention pond, increasing the fertilizer runoff into the pond. This has led to algal bloo

ms in the pond which periodically reduce the amount of dissolved oxygen available in the water. What will be the most likely long term effect on the fish population living in the pond if the situation with the fertilizer does not change

<span>Algae blooms are the consequence of large amounts of fertilizers in the water. Algae use the presence of increased nutrients and enhance their own growth. It is known that they produce an oxygen in the photosynthesis, so it is not a problem while they are still alive. But when these organisms die, their decomposition begins. For the process of decomposition, the oxygen is needed and ultimately it will be depleted from a body of water. This could lead to the death of aquatic animals that depend on oxygen. So, in the population will survive only those who are able deal with the lack of oxygen in the water</span>

A plant contains the alleles Gg for green pod
Viefleur [7K]

Given:

Allele for green pod colour = Gg (Heterozygous)

Allele for Yellow pod colour = gg (Homozygous)

Explanation:

Parents: Gg x   gg

When this two parent are crossed, it leads to the following F1 generation (off springs):

<em>• Gg (green colour pod) </em>

<em>• Gg (Green colour pod) </em>

<em>• gg (Yellow colour pod) </em>

<em>• gg (Yellow colour pod) </em>

Form the produced offspring it can be inferred that the allele combination for green colour pod is Gg. Among the four off springs obtained 2/4 are green colour pod and 2/4 are yellow colour pod.

A student analyzed a viral genome and found that the genome had the following nucleotide composition.
lapo4ka [179]

Answer:

Option A) Double-stranded DNA

Explanation:

Note that the presence of thymine, a pyrimidine nitrogenous base in the genome indicates the presence of DNA.

Then, the summation of 28% adenine + 20% thymine + 35% cytosine + 17% guanine to yield 100% confirms that the DNA is double-stranded.

Thus, the structure of the viral genome is Double-stranded DNA.
