Explanation:
Individuals with one form of lactose intolerance do not produce the
enzyme lactase because the gen coding for the production of lactase is
turned off in their cells. As a result, which of the following processes
does not occur for the gene?
Select one:
a. Transcription
b. Hydrogenation
c. Replication
d. Hydrolysis
Answer: Transcription - A
Explanation:
This problem is talking about the lac operon and the gene expression of lac operon. If the gene is turned off, then transcription, the generation of mRNA won't occur.

What are nucleotides in a stand of DNA that do not code for proteins called?
a. Non Sense Nucleotides
b. Waste Code
c. Non Coding DNA
d. Ribonucleic Byproduct
Answer:
C
Explanation:
Answer:
C.Noncoding DNA
Explanation:
''Noncoding DNA does not provide instructions for making proteins. Scientists once thought noncoding DNA was “junk,” with no known purpose. However, it is becoming clear that at least some of it is integral to the function of cells, particularly the control of gene activity.

Which energy conversion occurs in the cells of an animal, such as the
chipmunk shown in the photograph?
A. Kinetic energy
Nuclear energy
B. Light energy Chemical energy
O C. Kinetic energy → Potential energy
O D. Chemical energy → Potential energy
The energy conversion that occurs in the cell of an animal, such as the chipmunk, is Chemical energy → Potential energy.
What is the conversion of energy?Energy is neither created nor destroyed, it is just converted into another form of energy. This is called conversion of energy.
Here the food has chemical energy and which will be converted into potential energy in the stomach of the chipmunk.
Thus, the correct option is D. Chemical energy → Potential energy

The molecules of DNA are
__
so that each cell gets the same directions.
Answer:
Nucleotides
Explanation:
DNA structure
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code
What is the mass of a car that is going 2 m/s/s and then it hits a tree with a force for 6000 N?
Answer:
Mass = 2000kg
Explanation:
Mass = [tex]\frac{Force}{acceleration }[/tex]
= [tex]\frac{6000}{2}[/tex]
= 2000kg

Explanation:
In 1980, a long dormant volcano, Mount St. Helens in Washington state, erupted violently. The eruption wiped out the forested landscape and the wildlife. Months after the initial disturbance, the ash and rock strewn surface began to undergo primary succession.
Answer:
New vegetation and animals came to this place when the environment is suitable.
Explanation:
The ash and rock strewn surface began to undergo primary succession after few month when the soil is cool down because the soil has nutritive medium that helps the vegetation to grow on that land. In the primary succession, the new vegetation grows which is well suited to that environmental condition and uses the nutrients present in that soil for its growth and development. Many new organisms also came to this new landscape when the environment is suitable.
whould you be able to observe the DNA of a single cell?
Answer:
All living things have DNA: the chemical instructions on how to make a living thing, from humans to strawberries. Many people assume that because DNA is so small, we can't see it without powerful microscopes. But in fact, DNA can be easily seen with the naked eye when collected from thousands of cells.
Explanation:
There is higher abundance of lighter elements in the universe than heavier elements.
which sourfe of evidence supports that statement
Cosmic Microwave Background Expanding Universe Universe Composition
Answer:
Due to its formation in the supernova nucleosynthesis.
Explanation:
The higher abundance of lighter elements in the universe than heavier elements occurs due to its formation in the supernova nucleosynthesis. The lighter elements such as hydrogen and helium are present in abundant amount and formed in supernova nucleosynthesis as compared to other heavier elements which are formed through other events. The lighter elements occupy less volume and space as compared to heavier elements which is also a reason for their abundance.
Animals are a more complex life form than plants. What did plants do that allowed for animal life to develop? *
plants make oxygen which animals use to breathe
plants make carbon dioxide which animals use to breathe
plants make water which animals use to swim in
plants make sunlight which animals use to make vitamin D
I'm not sire if it's a single question answer but it looks like it's "A"
humans and animals make carbon dioxide which plants take in
plants don't make water, the water cycle "makes" it
and plants don't make vitamin D or sunlight
