Answer:
How do bacteria become resistant to antibiotics? Antibiotic resistance occurs when bacteria change in some way that reduces or eliminates the effectiveness of drugs, chemicals, or other agents designed to cure or prevent infections. The bacteria survive and continue to multiply causing more harm.

Answer: D on eduphoria
Explanation:
A student experiments with two solutions containing the same solute concentrations
in a beaker that is divided by a semipermeable membrane, as shown.
In which direction will the water move so that the concentrations of the solutions
remain constant on both sides of the membrane?
A in both directions at different rates
B in both directions at the same rates
C toward the right side of the beaker
D toward the left side of the beaker
Answer:
B in both directions at the same rates
Explanation:
Solutions with the same amount of solute concentration is referred to as ISOTONIC. In an isotonic solution, there is NO net movement of water molecules because there is no osmotic gradient i.e. difference in solute concentrations.
In this case, a student experiments with two solutions containing the SAME SOLUTE CONCENTRATIONS in a beaker that is divided by a semipermeable membrane. Due to the equal amount of solute concentrations in both solutions, water moves into and out each membrane at an equal rate.
In order for the concentrations of the solutions to remain constant on both sides of the membrane, WATER MUST MOVE IN BOTH DIRECTIONS AT THE SAME RATE.

Sally conducts an experiment measuring plant growth. She finds that after two weeks, a plant that receives water grew 4 cm, but the plant that received soda died. What is the term for what is being measured?
Answer:
The correct answer is - the dependent variable.
Explanation:
In any study or research, the variable is that measured or affected by the change occurs lace in an experiment is called the dependent variable. The dependent variable depends on the factors or the variables that are changed in the experiment.
In this particular study, the variable which is measure is the height or growth of the plant which depends on the change in the hydrating supply so the dependent variable will be - the growth of the plant.
Give two reasons why photosynthesis in plants slows down then stops during the fall then winter.
Answer: In the winter and fall there is less sunlight and there is less rain
There is a decline in photosynthesis after the sun sets in the winter and fall seasons. There is a decline of the enzymes in the plants that are responsible for the biochemical reaction.
These don't tend to work so so well during the winter cold winds blowing slows down the plant respiration process and hence the less photosynthesis to for the plants. Hence few sugars are not turned into metabolism.Learn more about why photosynthesis in plants slows down.

For this assignment, you will first make a model of a DNA strand using pop beads. This DNA strand
codes for a protein, which determines a trait in an organism. Next, you will change the base sequence of
your model in three ways to show how mutations occur. Then, you will compare the base sequence of the
mutated models to sequences on a key provided by your teacher to find out whether the mutated strand
creates a protein that is beneficial, harmful, or neutral. Finally, you will answer some questions to
summarize what you have done in this project. The Student Worksheet on the last few pages of this
document will help you complete your assignment.
Background Information
DNA is the genetic material passed from parent to offspring. It is an important molecule because it carries
instructions used for producing proteins. These proteins determine how an organism looks and functions.
DNA is a double-helix molecule. The two sides of the molecule, its backbone, are made of sugar
molecules and phosphate molecules. These sides are connected by rungs made of nitrogen bases. The
nitrogen bases of DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).
A gene is a segment of DNA that codes for a specific trait. The sequence of nitrogen bases in a gene is
copied from DNA into a strand of RNA in the nucleus of a cell. The RNA then moves out of the nucleus to
the ribosome. The ribosome uses the information that RNA copies from DNA to produce proteins that
have specific shapes and functions. The shapes of proteins help them perform their job. If the shape of
the protein is changed, the protein may not be able to perform its function. A mutation, which is a
permanent change in the DNA sequence in a gene, may change the shape of the protein it codes for.
Types of mutations include substitution, insertion, and deletion. The effects of mutations on organisms
may be beneficial, harmful, or neutral.
Answer:
This type of mutation occurs when one or more base pairs are added to the gene sequence.
✔ insertion
This type of mutation occurs when one or more base pairs are removed from the gene sequence.
✔ deletion
This type of mutation occurs when one or more base pairs take the place of other base pairs in the gene sequence.
✔ substitution

What happened when there was not enough carbon dioxide in the atmosphere to trap the sun's heat about 600 mya?
Answer:
Decreased Temperatures
Explanation:
Because carbon dioxide traps heat in the atmosphere, a lessening of atmospheric carbon dioxide concentrations would mean that more heat could escape into space. This would result in a net decrease in the Earth's average temperature, assuming other factors remain the same.

explain why the suspension of isolated chloroplasts became alkaline when illuminated?
Answer:
Yes, protons are pumped across the membrane, but flow right back again through the ATP synthase. More important is that illumination is required for carbon fixation. As photosynthesis runs, the chloroplasts remove CO2 from the water they are suspended in. In solution, CO2 forms carbonic acid, so removing CO2 will reduce the level of carbonic acid, raising the pH.
Explanation:
Chloroplasts are the primary cell organelles involved in the conversion of light energy into stable chemical energy through photosynthesis. The chloroplasts will become alkaline due to a rise in pH and a reduction in carbon dioxide.
Chloroplast is the green-colored cell organelle, primarily involved in the conversion of light energy into chemical energy.
When the isolated chloroplasts are illuminated, the suspension in which chloroplasts are suspended becomes alkaline. It is assumed that protons are pumped in from the medium to the thylakoids.
As photosynthesis takes place, the chloroplasts remove carbon dioxide from the suspension, which causes an increase in the pH of the suspension.
Therefore, the formation of carbonic acid from the CO2 will raise the pH.
