I think it is the grasshopper.
Answer:
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.
Rising air cools which results in evaporation.

What are THREE consequences of a warming Earth over the next 50 years?
Answer:
increase in sea level due to the melting of glacierswarming of the sea / oceans / river will gradually kill marine lifedesertification.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.

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 level of organization for All living organisms on Earth
Answer:
The highest level of organization for living things is the biosphere; it encompasses all other levels. The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.
Explanation:
Hope it helps!
Answer: biosphere
Explanation:
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.
why is only one nucleotide added at a time during DNA replication?
- to maintain the DNA mutations at an equal rate
- to reduce DNA mutations
- to increase DNA mutations
- to pass DNA mutations to the new cell
Answer:
answers is to increase DNA mutations
this is correct answerl hope it's helpful for u...
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.

are two epigenetic mechanisms that can prevent DNA from being accessible to transcription molecules. When the DNA is unwound, molecules that bind to determine when and how to transcribe genes. When gene transcription begins, a special type of protein known as binds to a promoter and assembles RNA. An activator is a transcription factor that binds to and promotes transcription. A repressor is a transcription factor that binds to and prevents transcription. Even if a gene is transcribed, its ultimate translation and expression can be silenced by
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.

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 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
reactant - product

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.

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).
