Answer:

C. Cutting down forests.

Explanation:

Carbon dioxide is an inorganic gaseous molecule with the chemical formula, CO2. It is naturally released into the atmosphere via a lot of processes. However, CO2 is the most important greenhouse gas as it contributes the most to the global warming effect of the Earth.

The effects of an increase in CO2 concentration in the atmosphere is as follows:

- increase in water contamination and floods

- ocean acidification

- reduction of cold-related deaths

However, the cutting down of forests is not an effect of an increase in CO2 concentration but rather a cause.

A medical test indicates that a patient has a defective protein. This
OleMash [197]

Answer:

number of nitrogen bases

Explanation:

<em>The correct answer would be the number of nitrogen bases.</em>

<u>A defective protein is usually caused by mutation, which is defined a change in the DNA sequence of an organism.</u>

Mutation can occur in a variety of ways including:

<em>1. Deletion of nucleotide base sequence in the DNA</em>

<em>2. Addition (insertion) of nucleotide base sequence in the DNA</em>

<em>3. Duplication of nucleotide sequence in the DNA</em>

<u>A change in number of phosphate molecules, sequence of subunits DNA and sequence of sugar molecules if possible in nature, do not lead to mutation if the change does not affect the sequence of DNA.</u>

Hence, the correct option is number of nitrogen bases.

Which option identifies the outcome of the following scenario?
JulsSmile [24]

Answer:

I believe the answer is 'She will have a high energy level due to the carbhohydrates in the bread group'

Explanation:

or The reason is that Carbs are sugars and sugars are known to give you energy if you don't overdo the carbs/sugars. Marianne had the tuna sandwich for lunch then pasta for dinner but for breakfast, she had eggs that are protein so she could have energy starting from breakfast then had lunch which carried on that energy.

Hope this helped :)

Put the following events in the correct order:
Wewaii [24]

Answer:

Explanation:

c. Transcription of one DNA strand results in mRNA, which is a complementary copy of the information in the DNA.

a. The mRNA leaves the nucleus and goes to a ribosome open choices for ranking.

b. The building blocks of proteins, are carried to the ribosome by tRNAsAmino acids.

The process of deoxyribonucleic acod starts with replication to transcription and translation.

Replication involves the formation of a complementary base from a old or template DNA Strand this then serve as a template for transcription.

transcription involves the coping of information on the DNA to an intermediate mRNA ( messanger ribonucleic acid) in the nucleus which then move from the nucleus to ribosome in the cytoplasm where translation occurs.

Translation is the conversion of the information on the mRNA to an amino acid with the help of enzyme transferse ribonucleic acid(tRNA).

Hence the arrangement is from C ---- A-----B.
