What biotic and abiotic factors control viral activity in the sea

Biology

My name is Ann [436]3 years ago

Answer:

The abiotic and biotic factors that control viral activity at sea are:  Sunlight, presence of bacteria, presence of eukaryotic microorganisms and presence of suspended particles.

Explanation:

As you already know, viruses are obligatory acellular particles and tiny parasites. They can be present in different environments, including the sea, where they can establish viral activity in different environments.

Viruses are composed of a nucleic acid molecule and a protein coat. This nucleic acid is highly changeable, being able to modify the viral activity of several forms.

Under the sea the main factors that can cause these mutations that modify viral activity are:

  • Solar radiation, through UV waves. These waves can destabilize the nucleic acid causing a mutation.
  • These viruses can "swallow" particles suspended in the aquatic environment. These particles can become involved with the nucleic acid, modifying it.
  • The presence of bacteria capable of parasitizing a virus through its enzymes can also cause changes in viral activity. Just like eukaryotic microorganisms.

<h2>Biotic and Abiotic Factors Controls Viral Activity in Sea </h2>

Firstly, biotic are living components and abiotic are non living. Abiotic are the temperatures of ore and other items that are non-living. In the stream, the biotic factor can be small toads, shrubs, fish anything existing in the sea. In the sea, the biotic factors are any great fish or sea beings existing in that region including the any tiny bodies. In this way, all factors and components control viral activity in the sea.

Meiosis reduces chromosome number and rearranges genetic information. Explain how the reduction and rearrangement are accomplish
Alisiya [41]

Answer:

Explanation:

Meiosis is a form of cell division that occurs in the sex cells of organisms. It ensures the reduction of a diploid cell to an haploid cell to allow for the formation of a diploid zygote after fertilization (contribution of both parents haploid sex cells to give a diploid zygote). Thus, this process is very essential and important.

The reduction is accomplished by 2 divisions after the duplication of chromosomes

- first division: separation of homologous pairs of chromosomes (this reduces the total in half)

- second division: separation of sister chromatids of a chromosome.

The rearrangement in meiosis occurs by crossing over/genetic recombination.

This is the exchange of genetic material between homologous pairs of chromosome bringing about a rearrangement and genetic variation

An example of a chromosomal abnormality that arises as a result of defects in this process is the Down Syndrome which is caused by a nondisjunction of the chromosomes 21 pair in a sex cell.

This condition produces offsprings that have some characteristic facial features, short stature etc

Cellular respiration—an overview what are the phases of cellular respiration?
Papessa [141]

Cellular respiration:

Cellular respiration is the process by which cell break down glucose with oxygen to store the energy as adenine triphosphate or ATP. Energy from ATP is used to help the cell perform daily functions like growing, dividing and repairing itself. Glucose can either be created through photosynthesis in plant cells or ingested in animal cells.

There are four phages of cellular respiration.

• Glycolysis

• Transition stage

• Citric acid cycle

• Electron transport chain

Genotypes for fur length dominant
G: FF, and Ff (These are the genotypes for short fur, short fur is a dominant gene.
P: Short fur is dominant
Genotypes and phenotypes for fur length recessive
G: ff
P: Long fur is recessive
If you have a hamster with short fur, the possible genotypes the hamster could have is FF, and Ff
If you have a hamster with long fur, the possible genotype is ff.
