3. Why is water regarded as the universal solvent?
A. because water is nonpolar
B. because water is polar
C. because water can exist naturally as a solid, liquid or a gas
D. because water is everywhere​

Answers

Answer 1

Answer:

B

Explanation:

More substances dissolve in water than in any other chemical. this is because of the polarity of its molecules. H²0 has a small positive electronic charge and the oxygen side has a small negative charge. the negative and positive charges help water dissociate ionic compounds into them.

If a cell has 14 chromosomes, how many chromosomes will each daughter cell have after mitosis and cytokinesis?
Why is this important?

Answers

Answer: After mitiosis, each daughter cell will also have 12 chromosomes. Cytokinesis is just the last stage of telophase, where the cell completely forms the two daughter cells. Telophase does not form chromosomes.

Explanation:

If a cell has 14 chromosomes, there are 14 chromosomes in each daughter cell.

What happens in Mitosis?

There are four stages of mitosis: prophase, metaphase, anaphase and telophase.

1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres.

2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell)

3) Anaphase: sister chromatids are pulled to opposite poles of the cell

4) Telophase: nuclear envelope reforms, chromosomes unfold into chromatin, cytokinesis can begin.

If a cell has 14 chromosomes, there are 14 chromosomes in each daughter cell.

equation of gaseous exchange in plants​

Answers

Answer:

See the answer below

Explanation:

Gaseous exchange in plants involves the entering of oxygen and the exit of carbon dioxide in its place. It is an important process that helps sustains the life of plants, just like every other living organism. The oxygen that enters is utilized in the process of respiration during which carbohydrates are broken down to unlock their energy for metabolic activities.

Oxygen usually diffuses-in through the stomata while the carbon dioxide diffuses in the opposite direction. The summary of the gaseous exchange is summarized in the equation below:

  Glucose (food) + Oxygen ---------> Carbon dioxide + water + energy

Or better still;

    [tex]C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + ATP[/tex]

Which statement about infiltration is TRUE? Group of answer choices groundwater is an unsafe (dangerous) source of water not meant for drinking Groundwater can remain in subsurface storage for long periods of time groundwater can NEVER return to the surface groundwater will ALWAYS discharge into a body of water

Answers

Answer: Groundwater can remain in subsurface storage for long periods of time.

Explanation:

The ground water is the water reservoir that gets accumulated beneath the earth crust due to the accumulation of water that seeps into the soil and rock due to the absorption by water bodies river, lakes, ponds, oceans, and rain or any kind of precipitation. The groundwater remains as a subsurface storage of water until the site of groundwater is searched and water is extracted from it for household, agricultural or industrial purposes.

private sector international conflict would be a conflict between a U.S. computer company, and a Japanese company which was supplying motherboards for the U.S. company. If the Japanese company had a contract requiring them to ship 10,000 motherboards a month, but they only shipped 6,000, this would cause a private international conflict.

Answers

Answer:

The correct answer would be - option C. the time that it takes you to get to the school.

Explanation:

The dependent variable is the factor or variable in any research or experiment is the variable that depends on the independent variable which means it changes with the change in the independent variable.

Here the time the different vehicle takes to get to the school is a dependent variable as it depends on the fact that which vehicle is using and changes with the change in the type of vehicle.

How does the process of natural selection account for the diversity of organisms that Darwin observed on the Galapagos Islands?

Answers

Answer:

Since each island is very different, birds from each of these islands all have different beaks, colorations, and sizes depending on the natural environmental factors surrounding their island.

Explanation:

I would also add in how birds had to adapt with different beak lengths and sizes in order to be able to get the food type that was most abundant. Natural selection was abundant in this case if one food source (say small seeds) was scarce, a bird with a small beak 1. Had very little if no small seeds to eat and 2. If there were large nuts that required breaking open (ability with birds for larger beaks to do so), the small bird could not break them open and then would unfortunately probably starve to death. Thus, natural selection occured so the birds with the large beaks were able to carry on their traits while the birds with the small beaks did not have as great of an opportunity (if not opportunity) to carry on their traits.

Since each island is very different, birds from each of these islands all have different beaks, colorations, and sizes depending on the natural environmental factors surrounding their island.

What is positive feedback loop?

A positive feedback loop is a feedback loop that occurs in nature when the product of a reaction leads to an increase in that reaction.

A negative feedback loop, on the other hand, occurs when increased output from the system inhibits future production by the system.

(brainliest if right!) How is the dispersive model different from the semiconservative model of DNA replication?

1. In the dispersive model, each strand of both daughter molecules contains a mixture of old and newly synthesized DNA, and in the semiconservative model, each new double helix consists of one old and one new strand.
2. In the dispersive model, the old double helix is degraded, and in the semiconservative model half of its nucleotides are used in the construction of two new double helices.
3. In the dispersive model, one of the two resulting double helices is made of two old strands, and in the semiconservative model the other is made of two new strands.
4. In the dispersive model, one strand of the new double helix is made of DNA, and in the semiconservative model the other strand is made of RNA.

What does mitosis do that the cell would do wrong if it just split down the middle in cell division?

Answers

Mitosis is when a DNA error, aka mutation, occurs in a body cell. When cells divide, it needs a copy of the DNA. During DNA replication, that error can cause the instructions for building proteins to differ. The change can not affect offspring. Meiosis is the same situation, but in sex cells. This can be transferred to offspring.
