What are X-linked traits?
Answer:
X-linked is a trait where a gene is located on the X chromosome.
Explanation:
Humans and other mammals have two sex chromosomes, the X and the Y. In an X-linked or sex linked disease, it is usually males that are affected because they have a single copy of the X chromosome that carries the mutation.
Evolution is the process by which populations of organisms can change over time. How is directional selection related to evolution?
Answer:
Directional selection occurs when individuals with traits on one side of the mean in their population survive better or reproduce more than those on the other. It has been demonstrated many times in natural populations, using both observational and experimental approaches.

Rain makes up part of earth's water cycle
Water evaporates from streams, lakes, and oceans, then condensation and precipitation occur in the form of rain.
Explanation:
I'm pretty sure this question is implying that the answers should be directly related to the water cycle. While some of the other sentences might have some truth to them, they are too vague to be considered fact, and they're not necessarily related to the process of the water cycle.

A student wrote steps to show the energy transformations involved in producing, eating, and digesting food. Which step shows an incorrect transformation?
a. Radiant energy from the sun changes to chemical energy in a plant.
b. When an animal eats a plant, chemical energy in the plant changes to radiant energy from the sun.
c. After an animal eats a plant, chemical energy changes to thermal energy.
d. In the animal’s body, chemical energy is converted into mechanical energy when it’s used for muscle movement.
Answer:
B
Explanation:
When an animal eats a plant, the energy doesn't change to radiant energy because it's eaten and it isn't living to produce radiant energy.
The steps which shows an incorrect transformation is when an animal eats a plant, chemical energy in the plant changes to radiant energy from the sun. Thus, the correct option will be B.
What is Energy transformation?Energy transformation is also known as energy conversion. It is the process of changing energy from one form to another form. Energy is a quantity which provides the capacity to perform the work or moving in space, or provides heat.

What would happen to the concentrations of Pyruvate, NADH and intermembrane H+ if the Krebs Cycle stopped working?
Answer:
Pyruvate will increase
NADH will decrease
H+ will decrease
Explanation:
I just took the test
If the Krebs Cycle stopped working, the Pyruvate will increase NADH and intermembrane H+ would decrease
In the Krebs Cycle, pyruvate is used to make a molecule called NADH and also makes ATP. Pyruvate would increase and no NADH would be made by the Krebs Cycle so it would reduce. Without NADH, the ETC would not get electrons. No electrons would pass down the chain, so no H+ would be moved. The concentration of H+ reduc because ATP synthase would still use themConclusively, If the Krebs Cycle stopped working, the Pyruvate will increase, NADH and intermembrane H+ would decrease.

Which example best shows that the chemistry of water is helpful to plants?
Answer:
water polarity causes cohesion that pulls other water molecules up through a plant.
Explanation:
Water for plants is essential because it constitutes one of the necessary elements so that they can generate their food through the process called photosynthesis.
In effect, plants take the hydrogen from a water molecule and discard the oxygen, providing the atmosphere with this essential gas for life.

Michael was watching the rain hit the sidewalk in front of his house. After a few minutes, he noticed a change in the precipitation and saw that the precipitation had changed into ice pellets. The falling ice pellets later changed back to rain, and then the rain stopped and the sun came out. Relate each stage of the water to cycle to the way it affects the weather.
Answer:After a few minutes, he noticed a change in the precipitation and saw that the precipitation had changed into ice pellets The falling ice pellets ... The falling ice pellets later changed back to rain, and then the rain stopped and the sun came out.
Explanation:
The stages of the water cycle that relate to the changes in weather that Michael observed are various like evaporation , Condensation, Precipitation which are the various sets like the mentioned.
What is evaporation ?Evaporation: The sun heats the surface water and causes it to evaporate. This stage is not directly related to Michael's observations, but it is an important part of the water cycle.
Condensation: As water vapor rises into the atmosphere, it cools and condenses into clouds. This stage is also not directly related to Michael's observations, but it sets the stage for the precipitation that follows.
Precipitation: When the conditions in the atmosphere are right, the water droplets in the clouds combine and fall to the ground as precipitation. In Michael's case, the precipitation started as rain and then changed to ice pellets. This change occurred because the temperature in the atmosphere dropped, causing the rain to freeze into ice pellets. The ice pellets eventually melted and turned back into rain.
Runoff: After precipitation falls to the ground, it can either be absorbed into the ground or flow across the surface as runoff. This stage is not directly related to Michael's observations, but it is an important part of the water cycle.
Transpiration: Water that is absorbed by plants is released back into the atmosphere through a process called transpiration. This stage is also not directly related to Michael's observations, but it is an important part of the water cycle.
Overall, Michael's observations demonstrate how changes in temperature and atmospheric conditions can cause precipitation to change from rain to ice pellets and back again. These changes in precipitation can have a significant impact on the weather, as they can affect things like temperature, humidity, and wind patterns.

What do stem cells do
Answer:
Stem cells are the body's raw materials — cells from which all other cells with specialized functions are generated. Under the right conditions in the body or a laboratory, stem cells divide to form more cells called daughter cells. No other cell in the body has the natural ability to generate new cell types.
