Answer: RNA polymerase
Transcription is carried out by an enzyme called RNA polymerase and a number of accessory proteins called transcription factors. Transcription factors can bind to specific DNA sequences called enhancer and promoter sequences in order to recruit RNA polymerase to an appropriate transcription site.

How are food webs related to energy flow within an ecosystem?
Explanation:
Each living thing in an ecosystem is part of multiple food chains. Each food chain is one possible path that energy and nutrients may take as they move through the ecosystem. All of the interconnected and overlapping food chains in an ecosystem make up a food web.

What are the main differences between a biomass pyramid and a pyramid of numbers?
Answer:
Pyramid of numbers represents the number of individual organisms at each trophic level. Pyramid of biomass represents the biomass present at each trophic level while pyramid of energy shows the energy available at each trophic level. All three types of pyramids are useful for characterizing ecosystem structure.
An automobile with a mass of 1200 Kg accelerates at a rate of 3 m / s2 in the forward direction. What is the net force acting on the automobile? ( Hint: Solve the acceleration formula for force. )
Answer:
3600 N
Explanation:
Force = Mass × Acceleration
= 1200 × 3
= 3600 N
I hope this helps
An automobile with a mass of 1200 Kg accelerates at a rate of 3 m / s2 in the forward direction. The net force acting on the automobile is 3600 N.
What is force?The push or pull on a mass-containing item changes its velocity. An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude. Force is calculated by multiplying the mass by acceleration.
The product of the molar mass of the compound and the moles of the substance are defined as mass
Here, the automobile has some mass and acceleration. And the force that is acting on the automobile is to be calculated.
Given, the mass is 1200 Kg
The time is 3 m/s2
Force = Mass × Acceleration
1200 × 3 = 3600 N
Therefore, the net force acting on the automobile is 3600 N.

While working on a group project for school, a student asked his group member to check his model of a section of DNA.
Which feedback would the student receive?
a) The model is accurate because all bases are paired correctly.
b) The model is accurate because it shows all components of each nucleotide.
c) The model is inaccurate because the base pairs are incorrect.
d) The model is inaccurate because it is missing the required bases in DNA.
Answer:
C) The model is inaccurate because the base pairs are incorrect.
Explanation:
By using the acronym Apples (Adenine) in Trees (Thymine), Cars (Cytosine) in Garages (Guanine) (ATCG). C would be the correct answer because the model goes by (CATCTGCA) which would be translated into; Cars (Cytosine) in Apples (Adenine), Trees (Thymine) in Cars (Cytosine), Trees (Thymine) in Garages (Guanine) and Cars (Cytosine) in Apples (Adenine).

Why is DNA a suitable molecule for information storage?
What is the function of genes in the DNA molecule?
Answer both these questions in a paragraph each (5 -1 0 sentences)
Answer:
#1 = DNA rather than RNA carries the hereditary genetic code in all biological life on Earth. DNA is both more resilient and more easily repaired than RNA. As a result, DNA serves as a more stable carrier of the genetic information that is essential to survival and reproduction. First, information stored in the DNA molecule must be copied, with minimal errors, every time a cell divides. This ensures that both daughter cells inherit the complete set of genetic information from the parent cell. Second, the information stored in the DNA molecule must be translated, or expressed.
#2 =They give instructions for a living being to make molecules called proteins. These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes. These chromosomes are made up of thousands of shorter segments of DNA, called genes. They give instructions for a living being to make molecules called proteins. Each gene stores the directions for making protein fragments, whole proteins, or multiple specific proteins.
