Explanation: A
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.

Answer:
Baltimore classification is a system used to classify viruses based on their manner of messenger RNA (mRNA) synthesis. By organizing viruses based on their manner of mRNA production, it is possible to study viruses that behave similarly as a distinct group.
Answer:
Baltimore classification is a system used to classify viruses based on their manner of messenger RNA (mRNA) synthesis. By organizing viruses based on their manner of mRNA production, it is possible to study viruses that behave similarly as a distinct group. Seven Baltimore groups are described that take into consideration whether the viral genome is made of deoxyribonucleic acid (DNA) or ribonucleic acid (RNA), whether the genome is single- or double-stranded, and whether the sense of a single-stranded RNA genome is positive or negative.

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.

in which order do plants development
Answer:
According to plant physiologist A. Carl Leopold, the properties of organization seen in a plant are emergent properties which are more than the sum of the individual parts. "The assembly of these tissues and functions into an integrated multicellular organism yields not only the characteristics of the separate parts and processes but also quite a new set of characteristics which would not have been predictable[by whom?] on the basis of examination of the separate parts."[7]

Explain what happens in each stage of mitosis.
no links
Answer:
Stage #1 Prophase: Chromatin fibers become coiled into chromosomes, with each chromosome having two chromatids joined at a centromere.
The mitotic spindle, composed of microtubules and proteins, forms in the cytoplasm.
The two pairs of centrioles (formed from the replication of one pair in Interphase) move away from one another toward opposite ends of the cell due to the lengthening of the microtubules that form between them.
Polar fibers, which are microtubules that make up the spindle fibers, reach from each cell pole to the cell's equator.
Kinetochores, which are specialized regions in the centromeres of chromosomes, attach to a type of microtubule called kinetochore fibers.
The kinetochore fibers "interact" with the spindle polar fibers connecting the kinetochores to the polar fibers.
The chromosomes begin to migrate toward the cell center.
Stage #2 Metaphase: The nuclear membrane disappears completely.
Polar fibers (microtubules that make up the spindle fibers) continue to extend from the poles to the center of the cell.
Chromosomes move randomly until they attach (at their kinetochores) to polar fibers from both sides of their centromeres.
Chromosomes align at the metaphase plate at right angles to the spindle poles.
Chromosomes are held at the metaphase plate by the equal forces of the polar fibers pushing on the centromeres of the chromosomes.
Stage #3: Anaphase: The paired centromeres in each distinct chromosome begin to move apart.
Once the paired sister chromatids separate from one another, each is considered a "full" chromosome. They are referred to as daughter chromosomes.
Through the spindle apparatus, the daughter chromosomes move to the poles at opposite ends of the cell.
The daughter chromosomes migrate centromere first and the kinetochore fibers become shorter as the chromosomes near a pole.
In preparation for telophase, the two cell poles also move further apart during the course of anaphase. At the end of anaphase, each pole contains a complete compilation of chromosomes.
Stage #4 Telophase: The polar fibers continue to lengthen.
Nuclei begin to form at opposite poles.
The nuclear envelopes of these nuclei form from remnant pieces of the parent cell's nuclear envelope and from pieces of the endomembrane system.
Nucleoli also reappear.
Chromatin fibers of chromosomes uncoil.
After these changes, telophase/mitosis is largely complete. The genetic contents of one cell have been divided equally into two.
Stage #5 Cytokinesis: Cytokinesis is the division of the cell's cytoplasm. It begins prior to the end of mitosis in anaphase and completes shortly after telophase/mitosis. At the end of cytokinesis, two genetically identical daughter cells are produced. These are diploid cells, with each cell containing a full complement of chromosomes.
Cells produced through mitosis are different from those produced through meiosis. In meiosis, four daughter cells are produced. These cells are haploid cells, containing one-half the number of chromosomes as the original cell. Sex cells undergo meiosis. When sex cells unite during fertilization, these haploid cells become a diploid cell.

What is the % of water inside the cell
Will osmosis occur
If so , which will water move (into or out of the cell )?
Will the cell swell or shrink ?
The cell is In what type of solution ? (Hypertonic , hypotonic ,isotonic ) help pls
The percentage of water inside the cell is 2.5 %. Water will move into the cell and it will swell. So it's a hypotonic solution.
What is osmosis?
Osmosis is the spontaneous diffusion or flow of water or other liquids over a semipermeable membrane, or one that prevents the passage of solutes, or dissolved compounds. The crucial biological mechanism was initially in-depth investigated in 1877 by German plant physiologist Wilhelm Pfeffer. Inaccurate investigations of leaky membranes, such as animal bladders, and the movement of water and other chemicals through them were previously conducted by other researchers.
A solution will tend to become more diluted by absorbing solvent through a membrane separating it from the pure solvent if the membrane is permeable to the solvent but not to the solute. The osmotic pressure, also known as the pressure exerted on the solution, can be raised to a certain level to halt this process. Jacobus Henricus van 't, Hoff, a Dutch-born chemist, demonstrated in 1886 that Henry's rule is obeyed if the solute is sufficiently diluted that its absolute vapor pressure is above the solution.
Therefore, the percentage of water inside the cell is 2.5 %. Water will move into the cell and it will swell. So it's a hypotonic solution.

If each of these food chains start with 10,000 grams of phytoplankton, how much reaches the highest trophic level in each food chain
Energy is transferred from one trophic level in a food chain to another. However, not all the energy available at a trophic level is transferred to the next.
Only about 10% of the energy in the lower trophic level gets to the immediate higher trophic level and the rest is lost as metabolic heat.
Thus, if a food chain starts with 10,000 grams of phytoplankton, the quantity that will get to the highest trophic level would depend on the number of intermediate trophic levels in between the lowest and the highest.
For every step the energy is transferred up the trophic level in the food chain, 90% of it is lost.
