Answer:

B

Explanation:

This macromolecule is DNA. Its stored genetic information in form of genes that translate to functional or structural proteins that make up an organism.  The DNA double helix is unzipped by helicases enzymes into single strands. RNA polymerase transcribes the single strands into mRNA. The mRNA is then translated into proteins by ribosomes. This is called the central dogma (DNA  RNA  Proteins).

During cell division, the DNA is replicated into two copies and each copy goes to each of the two daughter cells preserving, more or less, the same genetic code to the new cells.

Answers for Disruptions of the Cell cycle quick check
dangina [55]

An abnormal cycle during the cell cycle will be that Cytokinesis partially splits a cell into two, resulting in a cell with two nuclei.

When the cells become non-responsive to chemicals that control their growth, the cell cycle is disrupted and this then leads to the <em>cells</em> division uncontrollably which then leads to a disease that's called cancer.

Disruption to the cell cycle is dangerous to an organism because it can result in the production of abnormal or nonfunctional <em>cells</em>.

It should be noted that in a situation where the cells fail to recognize the chemicals that regulate the cell cycle, the <em>cell cycle</em> could become disrupted.

In conclusion, the regulation of the cell cycle is vital to the survival of <em>organisms</em> as it helps to control cell growth and division.

A student is experimenting with a substance that moves into the cell via facilitated diffusion.The student notes that as the con
Andrews [41]

Answer:

Facilitated diffusion in a cell has a limited amount of carrier and channel proteins, wherein if all are being used or saturated, can't transport the substances outside in to the cell, leading to the plateau of the substance.

Explanation:

In <u>low concentrations</u> of the substance outside the cell, <u>facilitated diffusion behaves like simple diffusion</u>, carriers and channels are not all used up. But in instances of <u>high concentration of the substance</u> outside the cell, <u>all the carrier and channel proteins are occupied</u> with the said substance. So <u>even if we increase the concentration of the substance, it will not increase the rate of diffusion.</u>

Difference between hypothesis and prediction examples
Butoxors [25]

A prediction is a guess what might happen based on observation.

Here are some steps to think about to make a dependable prediction:

Collect data using your senses, remember you use your senses to make observations.

Search for patterns of behavior and or characteristics.

Develop statements about you think future observations will be.

Test the prediction and observe what happens.


A hypothesis is a possible explanation for a observation or problem that can further be tested by experimentation. Hypothesis' are also known as educated guesses.

Here are the steps to form a hypothesis:

When developing a hypothesis think about any observations or previous knowledge you know about the variables.

Express what you think will be the effect of changing one of the variables (Independent variable) on the other variable you expect to change (Dependent variable).

Develop your hypothesis using a statement.

A example of a hypothesis statement would be, As the (independent variable) ( describe how you would change it) , then the (dependent variable ) will (describe the effect)
