It is not possible to see the different phases of mitosis in plant cells under a low-power objective microscope.
Under low-power objectives, individual plant cells can be seen as room-like compartments but the essential details of the contents of the cells cannot be seen. Thus, all the cells appear the same as if they are in an interphase phase of the cell cycle.
In order to view the different phases of mitosis in plant cells, higher magnifications such as high power would be required.

In carbon dioxide (CO2), there are two oxygen atoms for each carbon atom. Each oxygen atom forms a double bond with carbon, so the molecule contains two sets of double bonds. Two sets of double bonds means that the total number of electrons being shared in the molecule is two. four. six. eight.
Answer:
Eight
Explanation:
In a single bond there are 2 electrons
In a double bond there are 4 electrons
Two double bonds = 8 electrons
Answer:the answer would be eight hope this helps

Which RNA molecule is involved in translating a short sequence of RNA into an amino acid, acting like a molecular Rosetta stone?
a
snRNA
b
tRNA
c
mRNA
d
rRNA
Given what we know about the translation process, we can confirm that the RNA in question that aids in the process of translating a short sequence of RNA into an amino acid is mRNA.
mRNA is referred to as messenger RNA. This RNA molecule acts as just that, a messenger carrying the necessary code to create amino acids and therefore, proteins. This messenger binds itself to the ribosomes of a cell, which are in charge of reading the code, one codon at a time, and chaining together the corresponding amino acids.

Name the three common states of matter on earth.
Which states of matter have a set shape? Explain why this is, based on the animations you observed for the different states of matter.
Which states of matter have a set volume? Explain why this is, based on the animations you observed for the different states of matter.
The boiling point is the temperature at which a liquid substance will turn to vapor, and also the temperature at which vapor will condense to a liquid. The boiling point of ethanol is about 80°C, and the boiling point of water is about 100°C.
What can you conclude about the intermolecular forces in water and ethanol?
Do you predict water freezes at a higher temperature or at a lower temperature than ethanol?
Recall how different Van der Waals attractions and how ionic charges changed the movement of atoms in the animation. Do you think that Van der Waals attractions or ionic charges are stronger? Why?
1. solid, liquid and gas
2.Solid can move but gas and liquid is more flexible than solid. Solid has a fixed volume while liquid and gas takes the volume of its container. Solid stays in one place while gas and liquid is flexible.
3.Among the 3 state, solid has a fixed volume while liquid takes the volume of its container. When gas is compressed, it takes the volume of its container likewise.
the answer is solid, liquid and gas
Answer:
1. Liquid, Solid, Gas
2. Solid has a set shape. Solid can move but gas and liquid is more flexible than solid.
3. Solid has a fixed volume while liquid and gas takes the volume of its container. Solid stays in one place while gas and liquid are flexible.
4. A. The stronger the intermolecular forces in a liquid the higher the boiling point. Therefore, water has a stronger intermolecular force than ethanol.
B. Water molecules are more attracted to each other than ethanol (alcohol) molecules, because water has more hydrogen atoms bonded to oxygen. ... So, that's why alcohol has a much lower freezing point
5. Ionic charges are stronger.
Covalent bonds are known to have the strongest and most stable bonds since they go deep and into the inter-molecular state. A diamond is an example of a compound with this characteristic bond.
Ionic bonds are the next strongest molecular bond following covalent bonds. This is due to the protons and electrons causing an electro-static force which results to the strong bonds. An example would be Sodium Chloride (NaCl), which when separated is Na⁺ and Cl⁻.
Van der Waals forces, also known as Dispersion forces, are the weakest type of molecular bonds. They are only formed through residual molecular attractions when molecules pass by each other. It doesn't even last long due to the uneven electron dispersion. It can be made stronger by adding more electrons in the molecule. This kind of molecular bonds appear in non-polar molecules such as carbon dioxide.

Cell researchers are investigating the role of cyclins on mitosis and cell division. They notice that cyclins build up, cause the cell to progress through the cell cycle, then break down, thus ending the different stages of the cell cycle. A failure of the cell to break down which cyclin would most directly lead to increased cell division?
A) Cyclin A
B) Cyclin B
C) Cyclin D
D) Cyclin E
The inability of the cell to break down cyclin D would most directly lead to increased cell division.
What is cell division?Cell division is the process by which cells in the body divide their content and duplication of the chromosomes to produce new daughter cells.
In the cell cycle, proteins known as cyclins are required.
Cyclin D is required at the initiation and termination stage of cell division.
Therefore, based on the cell cycle diagram, inability of the cell to break down cyclin D would most directly lead to increased cell division.

How does one distinguish
between the left & right
sides of a heart?
Answer:
See explanation section for answer:
Explanation:
The left side of the heart contains the left atrium which allows oxygen rich blood to flow through the mitral valve and into the left ventricle. Whereas the right side of the heart contains the right atrium which allows the blood with poor oxygen levels to enter the right ventricle through the tricuspid valve.
Also, the left ventricle is larger than the right ventricle because the left ventricle is responsible for pumping the fresh oxygen rich blood throughout the body.

Describe a hypothetical result of the fluctuation test that would have supported the hypothesis that mutations occur in response to an environmental challenge, and explain how this result was different from the observed result described above
In order to support the hypothesis that mutations occur in response to an environmental challenge, the experiment in question would have to show an increase in mutation rates shortly after the environmental challenge was introduced.
When we test a hypothesis, we perform an experiment and gather data over the course of the testing. In order to obtain evidence that supports a hypothesis, we have to ensure that only one variable is changing and be sure to repeat the experiment to confirm the values measured.
Taking this into account, a hypothetical result of the fluctuation test that would support the hypothesis of mutations in reaction to environmental challenges would be to measure a spike in mutation rates in the generation following an environmental challenge, and then continue to do so with future post-challenge generations.
