Answer:
No, CREs usually don't account for differences in gene expression levels.
Explanation:
Cis-regulatory elements (CREs) are non-coding DNA regions that regulate adjacent gene transcription. They usually do it by binding to transcription factors. They are in charge of influencing the rate of which transcription occurs, and less with how much a gene is expressed. On the other hand, trans-regulatory elements are DNA sequences that encode for upstream regulators that can modify or regulate gene expression levels.
Therefore, cis elements are not really in charge of expression levels, mostly transcription rates of single genes, rather. Trans elements are more involved in expression levels.

4. Which areas seem to be most highly and quickly affected by a continued increase in
carbon emissions?
Answer: The atmosphere will be hit hardest by the increase in carbon. As the amount of carbon increases, it leads to increased warming of the atmosphere. Rising temperatures also increase the rate of evaporation, creating a more humid atmosphere and creating a virtuous cycle of warming.
This increase is beneficial as the Earth freezes due to the absence of carbon dioxide and other greenhouse gases in the air.
(sorry for my over-use of the the word increase)

and for the record The question wants me to explain how the blood in the heart reaches the lungs
It's everything in the photo; all you have to do now is explain it.
Blood leaves the heart through the pulmonic valve, it then moves through the pulmonary arteries which branches to the left and right lungs.
When the deoxygenated blood reaches the lungs, it is then oxygenated and returns to the heart through our pulmonary veins.
Hope this better explains it!

Explanation:
Fill out the data table below with the range of each factor that will produce the optimal number of oxygen bubbles.
The optimal ranges for the formation of oxygen bubbles vary between each plant, however, only water, c02, and temperature are limiting factors for photosynthesis.
This question is based on observations made during the course of an experiment designed to measure the optimal ranges at which oxygen bubbles form, given that these are an indication of photosynthesis.
Due to this, the information given will be generalized. Firstly, there is no exact optimal range of light for the formation of oxygen bubbles (photosynthesis) given that this is not a limiting factor.
Excess of light will have no effect on photosynthesis, only the lack of light can cause negative effects, therefore any light past the minimum threshold is fine.
On the other hand, water, light, and C02 are in fact limiting factors and have optimal ranges. For water, this optimal range varies greatly and therefore I cannot offer a general value, but an excess of water will "drown" plants by not allowing the formation of air pockets in the soil.
C02 sits at an optimal range of 1,000-1,300ppm for the best results. Lower concentrations cause a lower rate of photosynthesis given that it is the primary substrate for the process to begin. At too high levels, plants will have to adapt which can slow the process.
Finally, temperature is also a limiting factor for photosynthesis. Its exact value cannot be given since it varies greatly between plant species.
However, in general, terms, since it is an enzyme-dependent reaction, we can apply the general temperature at which enzymes function best which is around 37 degrees.

place each of the labels in the proper position to denote whether they would pass through the filtration membrane or not.
The labels that will pass through the filtration membrane are water, glucose, and sodium.
The labels that will not pass through the filtration membrane are red blood cells, lymphocytes, antibodies, and platelets.
The filtration membrane is a microporous glomerular barrier membrane made of polymeric materials that are used for the separation and filtration of substances based on their molecular weight.
Depending on the molecular size of a substance situated in the blood, we can determine if such substances can be filtered through the filtration membrane or not.
However, the lower the molecular weight of the substance, the higher their likelihood of filtration.
In the plasma, the substance that has a lower molecular weight are water, glucose, and sodium while substance associated with protein, blood cell, and platelets contains higher molecular weight.

What is the conversion factor from km. to ft.? If Joe traveled 12 kilometers, how many feet did he travel?
Answer:
The distance traveled by Joe in feet is 39,372 ft:
Explanation:
The conservation factor from km to Ft is 1 km = 3280.84 feet.
* In order to convert the value-form km to ft then we multiply the given value of the length by 3281.
*We are given that:
*Distance traveled by Joe = 12km
*Distance in feet = 12×3281
*Distance in feet = 39,372 ft
**Thus, the Distance traveled by Joe in feet is 39,372 ft.
The conversion factor from kilometers to feet is 3280.84 feet/kilometer. This means that there are 3280.84 feet in every kilometer.
So, if Joe traveled 12 kilometers, he traveled 12 * 3280.84 = 39370.08 feet.
1 kilometer = 3280.84 feet
12 kilometers = 12 * 3280.84 feet = 39370.08 feet
Therefore, Joe traveled 39370.08 feet if he traveled 12 kilometers.

Respiration is a process where many chemical bonds inside the body break and release energy. This energy is used to perform various activities such as moving muscles.
Explain the energy transformation in this process.
A. Chemical energy from broken bonds is transformed into mechanical energy for muscles.
B. Mechanical energy from broken bonds is transformed into chemical energy for muscles.
C. Mechanical energy from broken bonds is transformed into electrical energy for muscles.
D. Heat energy from broken bonds is transformed into electrical energy for muscles.
Chemical energy from broken bonds is transformed into mechanical energy for muscles. The correct option is A.
What is chemical energy?Chemical energy is the energy held in atom as well as molecule bonding.
Chemical energy can be located in things like batteries, biomass, oil, natural gas, and coal.
For instance, when humans burn wood in a fireplace or gasoline in a vehicle's engine, chemical energy is transformed into thermal energy.
Chemical energy, such as that held in the bonds of atoms and molecules, is stored energy. As a result of a chemical process, this energy is released.
Many chemical bonds throughout the body break during respiration, releasing energy. The movement of muscles is one activity that uses this energy.
Broken bonds' chemical energy is converted into mechanical energy for muscles.
Thus, the correct option is A.

What diagnostic test is useful for detecting hyperactivity of the thyroid gland during an evaluation of a thyroid disorder
Answer:
Blood tests that measure thyroxine and thyroid-stimulating hormone (TSH) can confirm the diagnosis. High levels of thyroxine and low or nonexistent amounts of TSH indicate an overactive thyroid. The amount of TSH is important because it's the hormone that signals your thyroid gland to produce more thyroxine
