Answer:
microRNAs
Explanation:
Within the cell, there are different types of regulatory non-coding RNAs (ncRNAs) such as microRNAs (miRNAs), small-interfering RNAs (siRNAs), piwi-interacting RNAs (piRNAs), long ncRNAs, etc., which are able to regulate gene expression. miRNAs are evolutionary conserved small ncRNAs (typically 18-23 nucleotides in length) known to inhibit gene expression by base-pairing with complementary target mRNAs, and thus trigger RNA interference (RNAi) pathways (e.g., mRNA degradation, inhibition of translation, etc). These miRNAs form part of a ribonucleoprotein complex named RNA-induced silencing complex (RISC) that acts to trigger RNAi mechanisms.

Use the dichotomous key to identify the leaf pictured above.
Mimosa
White oak
Scarlet oak
American beech
Answer:
C. Scarlet Oak
Explanation:
USA Test Prep
A dichotomous key is an essential scientific means by which the various organisms can be identified by the observable traits and attributes. The dichotomous key contains various questions related to the group of organisms that can have those traits.
Scarlet oak is the leaf in the picture.
How to identify the leaf based on key?The leaf of the Scarlet Oak is of the simple type that is it does not have smaller leaflet divisions and is attached to the petiole or the stem of the plant.Only one leaf at a time is attached to the petiole and not in bunches. The leaf of the plant is lobed that is has various protrusions like pointed or round.The leaf of the plant is pointed at the tips and shows that it belongs to the Scarlet Oak plant.Thus, option C is correct.

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.

Energy for the cell’s use is stored when
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! (^_^)

Based on the food chain, we cannot tell for sure
Explanation:
You can only identify omnivores with a food web. In food chains it only shows one source of food for each animal, so we wouldn't know if one of the animals eats both autotrophs and heterotrophs.

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.

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.

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.
