Answer: They have different Genotypes but the same phenotype
consist of either one or two long chains of repeating units called nucleotides. DNA and RNA are the two main types.
Answer:
In case of both DNA and RNA, in general it is the nucleotides.
Nucleotides basically consists of three parts. The sugar(deoxyribose in DNA and ribose in RNA, both of which are pentose sugars), nitrogenous base and a phosphoric acid group.
The only component that varies in the nitrogenous base. There are five different types.
1.Adenine(A)
2.Guanine(G)
3.Cytosine(C)
4.Thymine(T)
5.Uracil(U)
1 and 2 are known as purines.
3, 4 and 5 are known as pyrimidines.
In DNA, A base pairs with T by means of a double hydrogen bond and G pairs with C by means of a triple hydrogen bond.
In RNA, A base pairs with U by means of a double hydrogen bond and G pairs with C by means of a triple hydrogen bond.

How does using a microscope allow you to see what’s biotic or abiotic?
(how to know if a cell is abiotic or biotic)
Answer:
Abiotic factors refer to non-living physical and chemical elements in the ecosystem. Abiotic resources are usually obtained from the lithosphere, atmosphere, and hydrosphere. Examples of abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem.
Explanation:
In which location would fisherman most likely catch a greater number of fish?
at the shorline
O intertidal zone
O in an upwelling
O on the deep ocean floor
Answer:
On the deep ocean floor
Explanation:
This is because it is the lowest layer of the ocean where little or no light penetrate. In this floor, there are abundance of organic matter which the fish majorly feed and that is why they abundant there. The temperature in deep ocean floor is moderate and it's okay for their survival. The humidity also is moderate and that is why they live there.
Define the following:

Question
1. What happens to the host cell in the
lysogenic cycle?
Answer:
In a lysogenic cycle, the phage genome also enters the cell through attachment and penetration. ... During the lysogenic cycle, instead of killing the host, the phage genome integrates into the bacterial chromosome and becomes part of the host. The integrated phage genome is called a prophage.
Explanation:
Answer:
During the lysogenic cycle, the bacteria will enter the prophage and use its chromosomes to reproduce. This will continue until it eventually becomes the lytic cycle.

What is digested in the small intestine including the nutrients, substance, enzyme and final product of the thing being digested
Answer:
The pancreas and gland cells of the small intestine secrete digestive enzymes that chemically break down complex food molecules into simpler ones. or Complete digestion takes place in the small intestine as it finally absorbs the nutrients. The end products of digestion are amino acids, fatty acids, glycerol, and glucose.
Explanation:
If you're talking about the end product go with the latter
In a group of rose plants, some individuals have thorns and others do not. In this group, the
gene for the thorns trait has two alleles. The allele for not having thorns (n) is recessive to the allele for having thorns (R). A certain rose plant from this group has the heterozygous genotype Rr for the thorns gene. Based on this information, what is this plant's phenotype for the thorns trait?
A. Having thorns
B. No thorns
Answer:
The answer is having thorns, because the recessive allele is having thorns goes by the letter R, which is represented that way.

If the mass of Earth increased, how would your weight and your mass be affected?
Answer:
Answer: Your weight is nothing but force of gravity between the earth and you (as an object with a mass m). ... In this case, if the earth' mass goes up by 10%, then the force of gravity on you, or your weight, will increase by the same amount, that is 10%.

What action by an individual person is most likely to have a positive impact 1 point
on an ecosystem? *
A.planting pine trees to be sold as Christmas trees on private land.
B.planting native plants in a vacant lot.
C.planting a single economically valuable crops on 30 acres of land.
D.planting exotic shrubs in a community park.
Answer: planting native plants in a vacant lot
Explanation: you would rebuild the ecosystem that is native to the area
The action that would be taken by an individual person that is most likely to have a positive impact on an ecosystem may include planting native plants in a vacant lot. Thus, the correct option for this question is B.
What is an Ecosystem?An ecosystem may be defined as a place or an area that possesses members of different species togetherly and interact with one another for the purpose of food, space, shelter, and mating partner.
The growth of native plants will facilitate the stability of an ecosystem. This is because these plants grow more and reproduce naturally in order to exist in the ecosystem for a long period of time. While planting exotic shrubs in a community park, pine trees, and single economically valuable crops do not favor much in the stability of the ecosystem.
Therefore, the correct option for this question is B.

statements best explain why opal is found in places such
as Australia? Choose the two correct answers.
Answer:
Australia has large amounts of sandstone and silica.
and
Opal can only be formed where an ocean comes in contact with land.
Explanation:
because it needs standstone and a ocean to be able to create opal
Opal can only be formed where an ocean comes in contact with land. So, the correct option is (B).
What is an Opal?Opal is defined as a hydrated amorphous form of silica where the water content can range from 3 to 21% by weight, but is usually between 6 and 10%. Because of its amorphous property, opal is classified as a mineral, in contrast to the crystalline forms of silica, which are considered minerals.
Opal is arguably the most unique, diverse and beautiful, it does not have a defined crystalline structure which takes on many shapes and colors and thus is very unpredictable.
It can be formed where the sea is in contact with the sand, as in places such as those in Australia.
Thus, Opal can only be formed where an ocean comes in contact with land. So, the correct option is (B).
