David is developing a model of mitosis. He plans to represent a cell with a paper circle, and to represent 6 chromosomes with co

lored toothpicks.
Which would be the most useful representation of metaphase?
A. 3 toothpicks at one end of the circle, and 3 toothpicks at the opposite end of the circle
B. 6 toothpicks at one end of the circle, and 6 toothpicks at the opposite end of the circle
C. 6 toothpicks arranged in a line across the center of the circle
D. 6 pairs of toothpicks, or 12 toothpicks total, arranged in a double line across the center of the circle
E. 6 pairs of toothpicks, or 12 toothpicks total, arranged around the edge of the circle

<h3> What are cytokinesis and mitosis?</h3>

Mitosis is a cell division type that divides the parent cell and the genetic material into two alike daughter cells with the same chromosome numbers.

Cytokinesis is a process by which at the end of the telophase the cytoplasm of the cell starts dividing and results in the formation of the plate in plants and furrows in the animal, dividing the cell equally.

Thus, option "B" is correct.

A researcher found a method she could use to manipulate and quantify acetylation and methylation in embryonic cells in culture.
Gemiola [76]

Answer:a) decreased chromatin condensation

Explanation:

During eukaryotic cell division a chromatin becomes obvious and it is simply a mass of genetic material made up of DNA and proteins which condenses to form chromosomes.

The chromatin primarily function in the compression the DNA into a unit so compacted that will be so tiny and can fit within the nucleus.

Chromatin condensation is driven by condensins and interactions between histones.

Condensins however, are large protein complexes whose central role in cell division is chromosome organization and segregation.

Chemical manipulation as stated above is decreases the rate of chromatin condensation.

How many atp equivalents are consumed in the conversion of each of the following to a glucosyl residue in glycogen?
Nina [5.8K]
<h3><u>Answer;</u></h3>

Dihydroxyacetone phosphate - 1

Fructose-1,6-bisphosphate - 1

Pyruvate - 13

G-6-P - 1

<h3><u>Explanation;</u></h3>

1) Dihydroxyacetone phosphate = 1

G1P + GTP --> UDPG + PPi two P is equivalent to 2 ATP --->2 ADP + Pi) Therefore, two ATP equivalents - but UDP is the product and only one P needed

2 DHAP --> F1,6-BP -->F6P --> G6P -->G1P -->UDPG --> glucosyl residue

2) Fructose 1,6-bisphosphate = 1

3) Pyruvate = 13

2 pyr + 2 ATP --> 2 OAA

2 OAA + 2 GTP --> 2 PEP

2 PEP --> 2 2PG --> 2 3PG

2 3PG + 2 ATP --> 2 1,3 BPG

2 1,3 BPG + 2 NADH --> 2 G3P

2 NADH = 6 ATP

2 G3P --> DHP + G3P --> FDP -- > F6P + P

F6P --> G6P --> G1P

G1P + UTP --> UDPG + PP

4) Glucose-6-phosphate = 1

G6P -->G1P G1P + UTP --> UDP-GLC + 2 Pi

UDP-Glc + glycogen --> glycogen+ 1 Glc

How do humans impact the carbon cycle
Sedaia [141]

Answer:

Explanation:

Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. As a result, the amount of carbon dioxide in the atmosphere is rapidly rising.

Explain why the carbon cycle and the oxygen cycle are closely related?
Angelina_Jolie [31]

Answer:

The oxygen cycle is closely linked to the carbon cycle and the water cycle (see hydrological cycle). ... Carbon dioxide enters the carbon cycle or is taken up by plants for photosynthesis. During photosynthesis oxygen is evolved by the chemical splitting of water and returned to the atmosphere
