Answer:
1. Cytokinesis
2. G1
3. S
4. Mitosis
5. Interphase
6. G2
Explanation:
This question is describing the phases in the MITOTIC PROCESS. Mitotic process is grouped into Interphase and Mitosis. The Interphase involves stages such as G1 (first gap phase), S (synthesis phase) and G2 (second gap phase) while mitosis consists of prophase, metaphase, anaphase, and telophase.
1. The stage where the cell divides into 2 daughter cells with identical nuclei is called CYTOKINESIS
2. The G1 stage is the first stage of interphase which occurs immediately after the cell divides i.e. after cytokinesis
3. The SYNTHESIS or S stage of interphase is the stage where the cell copies its DNA i.e. duplicates its genetic material (DNA).
4. MITOSIS is the process directly after interphase that consists of four stages viz; prophase, metaphase, anaphase, and telophase. This is where the nucleus divides and each cell contains a complete copy of the parental chromosomes.
5. The INTERPHASE is the main stage of mitosis where the cell grows, carries out normal functions, and duplicates its DNA.
6. The SECOND GAP PHASE or G2 stage takes place before mitosis and after synthesis of DNA (S phase).
1. The stage where the cell divides into 2 daughter cells with identical nuclei is called:
Cytokinesis2. The stage of interphase which occurs immediately after the cell divides is known as:
G13. The stage of interphase is where the cell copies the DNA is known as:
Synthesis4. The process which directly occurs after interphase that consists of four stages. This is where the nucleus divides and each cell contains a complete copy of the parental chromosomes. This is called:
Mitosis5.The main stage of mitosis where the cell grows, carries out normal functions, and duplicates its DNA is known as:
Interphase6. The stage which takes place before mitosis and after synthesis of DNA is known as:
G2These are all the mitotic process where the cells are divided into interphase and mitosis and they further break down their process of cell division and differentiation.

A scientist is using a species of green algae to study electron transport chain in photosynthesis. He uses a laser to inactivate all of chlorophyll A in the algae, but leaves chlorophyll B intact (case 1). In a separate experiment, the scientist applies a chemical to the algae that inhibits PS I but does not affect PS II (case 2).
Answer:
The scientist done wrong by inactivating chlorophyll A and PS I.
Explanation:
The scientist done wrong by inactivate chlorophyll A and PS I. If he wants to study electron transport chain in photosynthesis, he needs chlorophyll A and PS I for that because the central role of chlorophyll A is to donate electron in the electron transport chain while on the other hand, the primary function of the photosystem I is the NADPH synthesis, where it receives the electrons for PS II.
Identify the tonicity of the solution surrounding the cell.
Answer:
Hypertonic
Explanation:
Hypertonic solutions have less water ( and more solute such as salt or sugar ) than a cell. Seawater is hypertonic. If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ).

Scientists discover two planets orbiting a distant star. The average distance from the star to Planet A is 4 AU, and it takes 432 Earth days for Planet A to orbit the star. If it takes 1,460 days for Planet B to complete an orbit, what is the average distance from Planet B to the star?
Answer:
3.3
Explanation:
no reason for the explanation
Answer:
C. 9 AU
Explanation:
The period (T) of Planet A is 432365=1.2 Earth years. The period of Planet B is 1,458365=4.0 Earth years. Kepler's Third Law states that
a3=kT2
Substituting the known values of a and T for Planet A, we have
43=k⋅1.22
64=k⋅1.4
k=45.7
Using this value for k, we can solve for the distance from Planet B to the star
a3=45.7⋅4.02
a3=731.2
a=9.0AU
An alternative solution is to notice that a3T2=k for both orbits, which means that the ratio a3T2 is the same for both orbits. So, 434322=x314582. Solving this proportion gives x3=729, so x=9.0AU.

when do birds use their teeth????
Answer:
to eat worms
Explanation:
Answer:
Birds do not have teeth, however...Explanation:
[tex]--------------------------------------------[/tex]
According to The Cornell Lab, "Birds do not have teeth, however, they may have ridges on their bills that help them grip food, but this does not count as teeth. So what about birds that have “tooth” in their name, like Double-toothed Kite? Some birds of prey have a sharp ridge or “tomial tooth” on the bill that they use to bite into their prey when subduing it. But these modifications to the bill surface are not considered the same thing as individualized teeth seen in other animals."

Which mechanism explains how both A and B antigens produce type AB blood?
Answer:
codominance
Explanation:
The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles are expressed equally in the phenotype, which means that both the A and B antigens are present on the surface of the red blood cells in type AB blood.
what is antigen?The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles in a heterozygous individual are fully expressed in the phenotype. Therefore, in the case of blood type AB, the A and B alleles are codominant, and both antigens are expressed on the surface of the red blood cells.
Hence, The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles are expressed equally in the phenotype, which means that both the A and B antigens are present on the surface of the red blood cells in type AB blood.

Osmosis requires energy
True
Or
False
Answer:
Diffusion and osmosis don't require the cell to expend any of its own energy, as they are passive processes. As we know both are passive processes and yet (in basic, short terms) diffusion is higher to lower and osmosis is lower to higher, so movement to concentration doesn't determine whether it is active or passive.
