Fluorescent microscopy can be used to visualize cellular structures in very high contrast.
What do the fluorescent dyes stain to make this possible?
a) All cells in G1
b) Replicating DNA
c) Specific molecules
d) Mitotic structures
Answer: it is C
Explanation:
Specific molecules
Fluorescent microscopy can be used to visualize cellular structures in very high contrast because fluorescent dyes STAIN specific molecules (Option C).
A fluorescence microscope is a microscope that uses fluorescent dyes to stain a particular specimen.Some examples of fluorescent dyes include, among others, Rhodamine, Acridine Orange and DAPI.For example, 4′,6-diamidino-2-phenylindole (DAPI) is a fluorescent dye that stains Adenine–Thymine (AT) rich regions in the DNA molecule.In conclusion, fluorescent dyes STAIN specific molecules (Option C is correct).

Pls help me, this is science btw.
Answer:
(B) and (E)
Explanation:
It is not option (A) because it says that Lactobacillus is a kind of bacteria that harms you, not is good for you, and parasitic bacteria are harmful to you, so not (A).
Not (C) because it does not make any sense whatsoever.
Not (D) since that says that S. typhi has a mutualistic relationship, which is good for both organisms, which is not true in this case.
It is (B) because the harmful bacteria, S. typhi is a parasite to humans.
It is also (E) since that says that the Lactobacillus bacteria does share a good relationship with humans.

similarities between animals and plants
Answer:
The similarities between plants and animals are listed below.
•Both are alive and at a certain stage, both will die.
•For reproduction, they have organs.
•They have energy converting and utilizing systems.
•They’ve got RNA and DNA.
•To grow and supply the body, they have cells that need unique nutrients, pH levels, macromolecules and so on.
•They’ve got a way to protect themselves.
•They have complicated structures for transportation.
In order to survive, they need and have enzymes.
Answer:
Both plants and animals are living things, this means they both have cells (plants have plant cells and animals have animal cells) and DNA. Both also has cellular respiration in their cells. They also require energy to grow.

Explain how the different forms of the gene produce different colours of coat.
Answer:
Skin colour is a good example of polygenic (multiple genes) inheritances. Skin colour is determined by the amount of the dark colour pigment melanin in the skin. This trait is determined by at least three genes. The genes that determine skin colour have two alleles each and are found on different chromosomes.
Answer:
The gene has 6 colours of coat.

How are these atoms used to make new molecules and what types of molecules are made? Where does the energy come from to produce these new molecules?
Answer:
Atoms used energy to make new molecules.
Explanation:
Atoms used energy to make new molecules through making bonds with one another because bonds allow atoms to attached tightly with each other. The energy come from the external environment in order to produce new molecules. So we can conclude that energy is the main ingredient needed for making new molecules and this energy is gained from the environment.
Answer:
I would like to help, but what are the new molecules they are producing? And what are the atoms the question is talking about?

Why does DNA need to be opened before mRNA
can be built?
Answer:
Since DNA contains recognition sites for RNA polymerase or its helper proteins to bind to, it must be opened before mRNA can be formed.The promoter region of the DNA opens up, allowing RNA polymerase to begin transcription. - gene (or, in bacteria, each transcribed group of genes) has its own promoter.Explanation:
DNA (Deoxyribonucleic acid )
DNA is a molecule made up of two polynucleotide chains that coil around each other to form a double helix and carry genetic instructions for the development, function, growth, and reproduction of all known organisms and viruses. DNA and ribonucleic acid are examples of nucleic acids (RNA).
Since they are made up of smaller monomeric units called nucleotides, the two DNA strands are known as polynucleotides. Each nucleotide is made up of a sugar called deoxyribose, a phosphate group, and one of four nitrogen-containing nucleobases (cytosine [C], guanine [G], adenine [A], or thymine [T]).

Which of the following statements about how surface currents affect climate is false?
Because surface currents are always warm, they warm the land they travel closest to.
A periodic change in the location of warm and cool surface waters in the Pacific Ocean changes global weather patterns.
A current that travels along the West Coast keeps temperatures along the coastline cooler than temperatures inland all year long.
England experiences warmer temperatures than other countries at the same latitude because of the warming effect of a surface current.
The effects of isotonic, hypotonic, and hypertonic extracellular environments on plant and animal cells is the same. However, due to the cell walls of plants, the visible effects differ. Although some effects can be seen, the rigid cell wall can hide the magnitude of what is going on inside.
Answer:
Yes.
Explanation:
Yes, there is same effects of isotonic, hypotonic, and hypertonic extracellular environments on plant and animal cells because both cells are more similar to each other. If a plant or animal cell is placed in a hypertonic solution, water will go outside the cell, and the cell will shrink, in isotonic environment, there is no water movement inside or outside of the cell, so there is no change in the size of the cell, while on the other hand, if a cell is placed in a hypotonic environment, water will enter the cell, and the cell will turgor.
