Answer:

Energy is if not the most fundamental unit of everything, along with matter, space and time, thus it is one of the foundations of all science.

Explanation:

Energy in science is like words in a book, you could not read the book without words, similarly, there would be no way to do science without energy. Take this example You can only measure the *speed* of an object if it has energy.

We could look at biolgy and see how photosynthesis makes use of energy. In photosynthesis we see plant cells converting energy from the sun into usful sugars to help the plant grow.

Now we could look at astronomy and see how energy is used, If you observe stars you can see the different brightnesses and masses, which tells you alot about what type of energy conversion is happening inside the star (nuclear fusion).

Answer:

A general decrease in transcriptional activation

Explanation:

When acetyl groups are added to histone proteins by acetyltransferase enzymes, the 30-nm chromatin fiber will not be formed because the proteins are prevented from doing so. This further destabilizes the chromatin structure and allows the occurrence of transcription. However, raising the cells to 40°C does not allow the acetyltransferase enzyme to function and hence the acetyl group will be hindered from being added to the histone protein which is the main target of the enzymes. Thus, transcription activation will be blocked because the chromatin and nucleosomes would remain stabilized.

8) What is the manipulated variable in this experiment?

Murrr4er [49]

Answer:

As the variables are not given, let us help with general explanation on manipulated variable.

Explanation:

A manipulated variable is an independent variable. In a scientific experiment, an independent variable can be described as a variable which can change naturally or which is changed by the researcher to check its effect on the dependent variable. The dependent variable is the variable which is under study and being tested.

For example, to check the difference in photosynthesis rate by light, the amount of light will be the independent variable and the rate of photosynthesis will be the dependent variable.

When an enzyme is denatured, what happens to the enzyme?

nignag [31]

Change the pH and the enzyme stops working. Increasing the temperature to 60°C will cause a permanent change to the shape of the active site. This is why enzymes stop working when they are heated. We say they have become denatured.

A woman who is a varsity soccer player has a bmi of 26, a waist circumference of 32, and 23percent body fat. what would you say

Dafna1 [17]

I would say about her body composition is that she is within recommendations for waist circumference and percent body fat. She has a normal BMI or Body Mass Index, she has a good body composition because she is a varsity player and she is exercising her body well. So the answer in this question is she is within recommendation for waist circumference and percent body fat.

Most cells fall within the range of 5-20 microns. What factors keep the size of the cell within these boundaries?

Tema [17]

Answer: Cytoplasm and organelles

Explanation:

Normally, a cell cannot attain a size greater than 20 microns due to the limits imposed by the size inter-relationships of its components. For example, there is a relationship between the amount of nuclear material and the size of a cell; this limits cells to a size where there is an optimal proportion of nuclear material to the rest of the cell.

Hope this helps :) and can I please get a brainly
