Viruses are often considered non-living because outside of a living cell, they do not exhibit the characteristics of living organisms: they are basically like crystals. But within a living organism, they become activated and are able to carry out life's activities like replication (a form of reproduction).

Answer:

Viruses are not made up out of cells they cant keep them selves in a stable state they dont grow and they dont make there own energy. So they are considered non-living.

Explanation:

Cells are living things in the body a virus is what the cells are trying to defeat and because there are no cells in viruses the cells in our body is what fights off the virus cause they are alive and processing in our body.

In genetics, a mutation refers to a change in the DNA sequence of a gene. A mutation that changes a GC base pair to AT is a transversion.

Mutations can occur in various ways, including substitutions, insertions, deletions, and inversions. One type of mutation is a base substitution, which involves the replacement of one nucleotide base with another.

When a mutation changes a GC base pair to AT, it is classified as a transversion. Transversions are a specific type of base substitution mutation where a purine (adenine or guanine) is replaced by a pyrimidine (thymine or cytosine) or vice versa. In this case, the GC base pair (guanine-cytosine) is changed to an AT base pair (adenine-thymine), representing a transversion mutation.

It is important to note that transversions are distinct from transitions, which involve the substitution of a purine for another purine or a pyrimidine for another pyrimidine. In this scenario, since the substitution involves different types of bases (a purine to a pyrimidine), it is categorized as a transversion rather than a transition.

The loss of aquatic plants in a lake due to acid rain pollution is likely to have significant impacts on the lake ecosystem.

Aquatic plants play crucial roles in the lake ecosystem. They provide food and habitat for a variety of organisms, including insects, fish, and other aquatic species. The loss of these plants can disrupt the balance of the ecosystem and lead to several consequences. Firstly, the absence of plants reduces the availability of food sources for herbivorous organisms, causing a decline in their populations. This, in turn, can affect the predators that depend on these herbivores for food.

Secondly, aquatic plants contribute to oxygen production through photosynthesis. With their loss, the dissolved oxygen levels in the water may decrease, leading to oxygen depletion and potentially harming fish and other oxygen-dependent organisms. Additionally, plants help stabilize the lake bed and prevent erosion, so their absence can lead to increased sedimentation and turbidity, affecting water clarity and light penetration, which further impacts other organisms.

It is crucial to give each organism a scientific name since each scientific name is unique to one species, making it easier for scientists to identify each organism.

A set of uniform standards form the foundation for scientific names. They can be used to locate an organism anywhere in the world since they are distinctive. Therefore, it is believed that common names for living things are less important than their scientific ones.

The Binomial Naming System is a two-name system used by scientists. The system used by scientists to name plants and animals describes the genus and species of the creature. Genus and species are the first and second words, respectively. While the second word is lowercase, the first is capitalised.

1 dm3 is a cube with dimension 1 deci meter

One cubic decimeter is the unit of volume which is exactly equal to one litre.

Volume of an object is defined as the amount of space within the object which the matter can be occupied.

Here,

It is said that volume is a derived quantity.

Volume is said to be a derived quantity because, volume is the product of length, breadth and height of a three-dimensional shape.

It is given that,

1 L = 1000 mL

1 L = 1 dm³

1L = (10cm)³ = 1000 cm³

We know that, 1 cm = 10⁻²m

So, we can write that,

1L = 1000 x (10⁻²m)³

1L = 10³ x 10⁻⁶m³

Therefore,

1L = 10⁻³ m³

Or

1 m³ = 1000 L

1 dm³ or 1 cubic decimeter is the unit of volume, which is equal to one litre.

Hence,

One cubic decimeter is the unit of volume which is exactly equal to one litre.

The theory of plate tectonics states that the Earth's surface is made up of several large, moving plates. These plates are constantly moving, colliding, and pulling apart due to forces generated by the movement of material in the Earth's mantle. The movement of these plates causes the creation of earthquakes, volcanoes, and mountain ranges as well as the formation of oceanic crust and the reshaping of continents over time. The movement of the plate is caused by the convection currents in the Earth's mantle, which causes the plate to move in a slow and steady way.

6.) Frequency of R: 0.5

7.)Frequency of R: 0.5

8.)Frequency of R: 0.375

Explanation:

5.) If R and B code for the different forms of the same protein then they are only a few possible out comes

6.) First calculate the total alleles in population

allele R= 40

Allele B=40

total allele = R+B= 40+40

=80

Now to find allele R frequency is:

(Total R alleles) / (Total allele in pop)

40/80=

0.5

7.)Calculate the total alleles

Alleles from for R

RR= 10

R=10x 2= 20

Multiply the value by 2 because there are 2 R alleles present in

RB=20

R=20

Number doesn't change there is only 1 R allele

Total R=20+20

=40

Alleles For B

BB=10

B=10×2

=20

Same thing here, two B alleles together so multiple by 2

RB=20

B=20

Total B= 20+20

=40

Total alleles in pop add

40+40

=80

Frequency of R

Total of R/Total Alleles

=40/80

=0.5

Answer:

The organism's genotype encodes their phenotype because the genotype corresponds to the characteristic that is determined by genes —formed by fragments of DNA— which are transcribed into mRNA to be translated into amino acid sequences in the synthesis of proteins, determining the morphological and functional characteristics of an organism, that is, its phenotype.

Explanation:

Genotype corresponds to the genetic information contained in the DNA, according to the sequence of nucleotides in its molecular structure. This genotype includes characteristics or polymorphisms that define the appearance and function of living beings.

Each DNA molecule constitutes a chromosome, formed by genes —DNA fragments— each of which determines specific characteristics.

When DNA is transcribed into mRNA, information is being sent that is necessary for the incorporation of amino acids into a protein that is being synthesized. The proteins, in turn, determine morphological and functional characteristics that constitute the phenotype of an individual.
