Karissa is conducting an experiment on the amount of salt that dissolves in water at different temperatures. She repeats her tests several times using the same procedure. What can Karissa do to further increase confidence in the results of her experiment?
Answer:
She could time how long it takes for each amount of salt dissolves in the waters. (as well as keep each amount of salt the same if she was not doing that already.)
Explanation:
This way, she could observe which water is best for dissolving solvents and which is most affective in the shortest amount of time. If she was not timing how long it takes for salt to dissolve in different temperatures of water, then the experiment may as well have been useless unless there is somehow a different objective.
Answer:
she could make sure the experiment follows a specific procedure that allows other scientists to produce the same findings
If a cell does not pass a checkpoint it may commit what, programmed cell death
Answer:
If the checkpoint mechanisms detect problems with the DNA, the cell cycle is halted, and the cell attempts to either complete DNA replication or repair the damaged DNA. If the damage is irreparable, the cell may undergo apoptosis, or programmed cell death 2.

1. Identify the following elements of hypothesis-based science in this example: (a) question, (b) hypothesis, (c) prediction, (d) control group, and (e) experimental group. (For additional information about hypothesis-based science, see Chapter 1 and the Scientific Skills Review in Appendix F.) 2. Explain how the types of data the researchers chose to collect enabled them to test their prediction. 3. What conclusion do you draw from the data presented above? 4. (a) Predict what would happen if, after 22 months, guppies from the transplanted population were returned to the source pool. (b) Describe an experiment to test your prediction.
Based in the experiment with the guppies, it can be concluded that natural selection is a factor of evolution.
What is a hypothesis?A hypothesis is an explanation put forward to explain an observation without prior testing.
From the observations in the guppies;
The question is whether natural selection is favors coloration in guppiesThe hypothesis is that natural selection determines coloration in guppies The prediction is that guppies with bright coloration will thrive in a predator free environment The control group is the source poolthe experimental group is the transfer poolthe conclusion from the data is that guppies with bright coloration are naturally selectedReturning the guppies from the transfer pool to the source pool will essentially reduce the population of the bright colored guppies due to predation.Therefore, it can be seen from the guppies that natural selection drives evolution of species.

Which sphere, regarding carbon, would be most immediately affected by a decrease in sunlight?
A.Atmosphere
B.Biosphere
C.Geosphere
D.Hydrosphere
PLZ ANSWER!
All the ecosystems on Earth are collectively referred to as the biosphere. Therefore, it comprises both live things and inanimate objects, such as sunshine and water. Thus, option B is correct.
What is the role of sunlight in biosphere?Photosynthesis is a process that organisms like plants, algae, and cyanobacteria used to turn carbon dioxide and water into organic molecules like carbohydrates.
The primary source of organic matter in the biosphere is this mechanism.
The sun powers the biosphere. This is so because the biosphere depends on the sun for its source of energy.
The compounds known as photosynthetic pigments catch the solar energy that powers the biosphere and use it to create organic molecules out of carbon dioxide and water.
Therefore, Biosphere regarding carbon be most immediately affected by a decrease in sunlight.

Explanation:
If light color is a recessive trait and the trees stay dark forever, could the light colored moths eventually become extinct? Why or why not?
Answer:
The light moths could become extinct eventually
Explanation:
If trees stay dark forever the light moths are easier to prey upon and eventually negative selection pressure will decrease the population of light moths until it is virtually nonexistent.
For a real life case of this, look into pepper moths and the Industrial Revolution.
If the light-colored trait is truly recessive, the moths may still carry the gene and could reappear in future generations.
What is a recessive trait?A recessive trait is a genetic characteristic that is only expressed when an individual inherits two copies of the recessive gene, one from each parent. In other words, a recessive trait is only observable when the dominant version of the gene is absent.
For example, if a person inherits a dominant brown-eye gene from one parent and a recessive blue-eye gene from the other parent, they will have brown eyes, as brown is the dominant trait. However, if both parents pass on the recessive blue-eye gene, the individual will have blue eyes, as there is no dominant gene present to override the recessive gene.

A test area of a urine reagent strip is impregnated with only sodium nitroprusside. This section will react with:
If the test area of a urine dipstick was impregnated with sodium nitroprusside only. This section will react as a false positive.
How to read urine tape?To properly assess pyuria, the tape needs to be in contact with the urine for 30 seconds to 1 minute. False-positive results occur with contaminated specimens, trichomonas infection, and drugs or foods that make the urine red.
Sodium nitroprusside is a potent vasodilator for parenteral administration with rapid action and short duration, being very effective in hypertensive emergencies and in the treatment of patients with acute decompensated heart failure.
With this information, we can conclude that if the test area of a urine dipstick were impregnated with only sodium nitroprusside. This section will react as a false positive.
