O A. Pond
O B. Lake
O C. Swamp
O D. Forest
Answer:
b lake your welcome
Explanation:
because lakes have trees that create the fresh water for the fishes to swim in i think?
An example of a freshwater wetland body is a lake. Thus, the correct option is B.
What is a lake?A freshwater wetland is a waterbody which is supplied with water from all the nearby streams and rivers. Freshwater wetlands are the ecosystems which are affected by the permanent or temporary inundation.
A lake is a naturally occurring, relatively very large body of water which is localized in a basin that is surrounded by land, with much slower-moving flow than that of any inflow or outflow streams that serve to feed or drain the lake. Lakes lie completely on the lands and are separate from that of the ocean, however like the much larger oceans, they also form a part of the Earth's water cycle by serving as many large standing water reservoirs as possible. Most of the lakes are freshwater, however some are salt lakes with salinities even higher than that of the seawater.
Therefore, the correct option is B.

It is made up of long chains of fatty acids.
It is made up of polymers of monosaccharides.
It is made up of long chains of nucleotides.
It is made up of polymers of amino acids.
Answer:
The surfaces of the leaves of many plants help to reduce water loss because they are not water-permeable. How does the biomolecule that makes up this surface differ from other biomolecules? It is made up of polymers of amino acids. It is made up of long chains of fatty acids.
Explanation:
The biomolecules that make up this surface of leaves differ from other biomolecules by the fact that they are made up of long chains of fatty acids. Thus, the correct option is A.
What are Biomolecules?Biomolecules may be defined as those types of molecules that are significantly present in the body of living organisms and are required to perform essential functions like cell division, morphogenesis, or development.
The long chains of fatty acids typically consist of a hydrophobic arrangement that prevents the movement of water from one part to the other. This specific property of forming a water barrier is only present in fatty acids.
Due to this, the surfaces of the leaves of many plants help to reduce water loss because they are not water-permeable, which means to prevent the migration of water.
Therefore, the correct option for this question is A.

What is the role of enzymes in the DNA replication process?
A. Enzymes read the DNA code and build a new DNA molecule from scratch.
B. Enzymes link together to form a template for a new DNA molecule to be built.
C. Enzymes split the DNA molecule into two rails and then transport corresponding nitrogenous bases to each rail.
D. Enzymes link adjacent nucleosides together, becoming an integral part of the structure of the new strands of DNA.
Answer: C. Enzymes split the DNA molecule into two rails and then transport corresponding nitrogenous bases to each rail.
Explanation: This would be known as the double helix because it is being split.
Different enzymes are involved in DNA replication: DNA polimerase, primase, helicase, ligase, and topoisomerase. The correct option is C. Enzymes split the DNA molecule into two rails and then transport corresponding nitrogenous bases to each rail.
---------------------------------------------
DNA Replication starts in some specific place named replication origin.
Helicase
This is the first enzyme that works in the replication origin. It separates the DNA into two strands allowing the replication forks to advance by unwinding the DNA. It breaks hydrogen bonds between nitrogenated bases pairs.Topoisomerase impedes the DNA double helix near the replication forks to get too coiled when the DNA is opening.
DNA polymerase III
This enzyme is responsible for DNA elongation. It is in charge of adding nucleotides to the growing chain, from 3' to 5' extremes. It includes only nucleotides that complement the original strand. They need to recognize a primer to begin.Primase is in charge of synthesizing primers.
DNA polymerase I eliminate ARN primers and substitute them with DNA.
DNA ligase seals the gaps that remain after replacing the primers.

Answer: This is known as eco-localization and when they emit these waves they reflect them in fish; that way they know exactly where they are.
The Doppler effect occurs when a source of waves and/or observer move relative to each other, resulting in the observer measuring a different frequency of the waves than the frequency that the source is emitting.

In prokaryotic cells, the cytoplasm is available, however, it is deficient in most cell organelles. It comprises both organelles and cytoplasm in eukaryotic cells, and both are present. There are mitochondria, which are the cells' powerhouse. There are two kinds of organelles present which is membrane-bound and non-membrane-bound.
Therefore, eukaryotic cells are also referred to as true cells having membraned nuclei.

What particles cannot pass through the cell membrane
Large molecules such as proteins and nucleic acids, charged particles (ions), and polar molecules such as glucose are examples of particles that cannot pass through cell membranes.
The lipid bilayer of the cell membrane makes it difficult for charged and polar substances to pass through. However, small, non-polar molecules and compounds that are lipid soluble can readily diffuse across the cell membrane. Aquaporins make it easier for water molecules to do this by facilitating osmosis.
The selective permeability of the cell membrane enables it to control the passage of molecules, preserving cellular harmony and functionality. In contrast, diffusion allows the easy passage of small, non-polar molecules such as oxygen, carbon dioxide, and lipid-soluble compounds through the cell membrane.
