is a dominant trait (R). What are the possible genotypes for their next child? Phenotypes? To solve this problem follow the steps below Step 1: Write out the parent genotypes cross: Step 2: Punnett square: Figure out the gametes. Put the parent gametes in the proper locations & fill in the boxes.

The possible genotypes of the offspring of the parents are RR, Rr, and rr.

<h3>What are dominant traits?</h3>

Dominant traits are characters which are always present in every generation.

A dominant trait is encoded for by the dominant allele of a gene.

Assuming the genotype of the parents are Rr and Rr.

The cross between them will give:

Rr × Rr = RR, Rr, Rr and rr.

Therefore, the possible genotypes of the offspring of the parents are RR, Rr, and rr.

A retrovirus hijacks a cell's machinery to turn its rna into dna, which is then inserted into the cell's genome so viral protein
Doss [256]
No this virus does not follow the Central Dogma of Biology. The Central Dogma refers to the process involved in cellular replication starting from the replication of DNA, followed by transcription of DNA to RNA, and finally translation of RNA to proteins.

Viruses are special because they hijack cells and use the cell's own mechanisms in order for it replicate. Retroviruses are even more special because they go against the unidirectional flow of the Central Dogma. This is done with the use of their <em>reverse transcriptase.</em>

Explain the role of air pressure, air masses and weather fronts in the formation of meteorological events such as thunderstorms,
PtichkaEL [24]

Hi,

here u go!!

Air masses are slowly pushed along by high-level winds, when an air mass moves over a new region, it shares its temperature and humidity with that region. ... For example, when a colder air mass moves over warmer ground, the bottom layer of air is heated. That air rises, forming clouds, rain, and sometimes thunderstorms.

hope it helps!!

Sveta_85 [38]

Answer:

The correct option is<em> b.  at each step, energy is lost from the system</em>

Explanation:

The amount of energy that travels from one trophic level to another is known to declines at each level. Infact, only 10% of the energy travels from one trophic level to another.

This is because most of the energy is lost by the organisms at each trophic level. It is due to the metabolic processes which occur in the organisms of each trophic level  and most of the energy is lost as heat.
