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.

what is the relationship between structure and function of molecules
Answer:
PS:Can I be brainliest.
Have a nice day
Explanation:
Each molecule has a characteristic size and shape that determines its function in the living cell. The shapes of molecules are determined by the positions of the atoms' orbitals. When an atom forms covalent bonds, the orbitals in its valence shell are rearranged.
Each molecule has a characteristic size and shape that determines its function in the living cell. The shapes of molecules are determined by the positions of the atoms' orbitals.
What is molecules?
The smallest component of a substance that possesses both its chemical and physical characteristics. One or more atoms make up molecules.
They may have the same atoms (for example, an oxygen molecule has two oxygen atoms) or different atoms if they have more than one (a water molecule has two hydrogen atoms and one oxygen atom).
Biological molecules like DNA and proteins can include thousands of atoms. When an atom forms covalent bonds, the orbitals in its valence shell are rearranged.
Therefore, Each molecule has a characteristic size and shape that determines its function in the living cell. The shapes of molecules are determined by the positions of the atoms' orbitals.

Why does a substance like caffeine not bioaccumulate but heavy metals like mercury and lead do? Explain where these toxins are stored in the human body. Hint: is caffeine fat-soluble?
Answer:
Brain, heart, lungs, liver, kidney
Explanation:
Caffeine does not bioaccumulate in our body but heavy metals like mercury and lead can accumulate because caffeine are fat-soluble and broken down into simpler substances and used by the body whereas heavy metals are not fat-soluble and also essential for our body to function normally but when these heavy metals are very in concentration it accumulated in our body and causes several problems in our body organs. These heavy metals accumulation occurs in the organs such as brain, heart, lungs, liver and kidney where it cause problems.
Caffeine is in organic molecules that are metabolized by the liver. Heavy metals are atoms that cannot be broken down. They can be sequestered in the bones or in fatty tissue (with methylmercury) and have a long residence time in the body.
These toxins are stored in the human brain, heart, lungs, liver, and kidney.
What are heavy metals and examples?
The word-heavy metal directs to any metallic chemical element that has a relatively high density and is toxic at low concentrations.
Examples of heavy metals include mercury (Hg), cadmium (Cd), arsenic (As), etc.
Thus, Heavy metals are atoms that cannot be broken down.

PLZ HELP ASAP!! Environmental factors can influence the gene expression in some organisms.
Describe how environmental factors can affect an organism’s phenotype.
Explain how light exposure can affect gene expression in organisms of the same species. Provide an example.
plz dont steal points
Answer:
The greatest of environmental factors on phenotype is on phenotypic plasticity, phenotypes that may change due to changes in the environment; ex: snowshoe hare have brown-colored fur in summer/spring and white fur in winter. Environmental factors may affect gene expression which may result in normal/abnormal phenotypic changes.
Explanation:
Does an unusually cold day in summer indicate that a region's climate has changed?
A
Yes; climate changes over the short term.
B
Yes; climate describes the temperature of a region at a given time.
C
No; although weather may change, climate does not change.
D
No; climate describes long-term average conditions.
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.
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.

ADP and P form ATP
Acetic acid is formed
Glucose is broken into pyruvic acid
CO2 is released from the reaction
AnswerA. ADP and P form ATP
Explanation:
Hope this is correct!
Answer:
ADP and P form ATP
Explanation:
The high energy is released in steps and picked up by ADP and P to form the high energy phosphate (ATP). For each two hydrogens passed down the chain, three ATPs are produced. At this stage, 36 ATPs are produced from the original glucose that started out in glycolysis. After the hydrogens have given up all of the excess energy they are combined with oxygen to form water. mark me brainy plz! (^_^)
