POSSIBLE POINTS: 2 A student wondered if different types of plants would produce different amounts of oxygen. A pea plant, a fern, and a cactus were growing in equal-sized containers with equal amounts of soil. The student measured the amount of oxygen produced by each. Identify one factor (other than the size of the container and the amount of soil) that should be held constant in this experiment. Explain why this variable needs to be held constant.
Answer:
The correct answer would be - the amount of water they get.
Explanation:
In any research or study, there are some variables other than the independent variable that can affect any experiment directly or directly. To avoid such conditions these variables are held constant.
In this case, the production of oxygen can be affected in all three plants due to various variables also such as the amount of soil, size of the container, amount of water all three different plant gets, and others.
Thus, the correct answer would be - the amount of water should be held constant.

where a mutation would take place in an organism
Answer:
The genome is composed of one to several long molecules of DNA, and mutation can occur potentially anywhere on these molecules at any time. The most serious changes take place in the functional units of DNA, the genes. A mutated form of a gene is called a mutant allele.
Explanation:
Answer:
DNA
Explanation:
Mutations occur in the nucleotide sequence of DNA

In year 5, the red population will decrease because a change in the habitat occurred in year three that favored red butterflies.
B.
In year 5, the blue population will decrease because a change in the habitat occurred in year three that favored blue butterflies.
C.
In year 5, the red population will increase because a change in the habitat occurred in year three that favored red butterflies.

Photosynthesis converts ______________________ and ___________________ into food-energy molecule ______________________ and gives off ____________
if the answer is outrageously incorrect you will be reported
Answer:
Photosynthesis converts Light and chemical energy in to food-energy molecule sugar and gives off Oxygen
Explanation:
6CO2 + 6H2O → C6H12O6 + 6O2
Photosynthesis is a chemical reaction that takes place inside a plant, producing food for the plant to survive.
Carbon dioxide, water and light are all needed for photosynthesis to take place.
Photosynthesis happens in the leaves of a plant.

What additional restriction enzyme would be used to cut out another gene flanked by a different restriction site?
Answer:
a clone
Explanation:
Restriction enzymes are DNA-cutting enzymes. Each enzyme recognizes one or a few target sequences and cuts DNA at or near those sequences. Many restriction enzymes make staggered cuts, producing ends with single-stranded DNA overhangs. However, some produce blunt ends.

This soil sample is the LEAST porous?
True or false
Answer:
False
Explanation:
Soil with least porosity
Thus, the correct answer is 'Clay soil. '
There are other types of soil that can be more crumbly, but this is not the least. Because porous means something is full of tiny holes or openings, you can see that this is the right word to match it with! The least crumbly, or porous would only have a little crack. Good luck, and I hope this helped!
Also....
Clayey soil is the least porous.
Clayey soil is the least porous soil as the spaces between the molecules of the soil is less and water cannot pass through them.
The heavily muscled men and straining poses of Rubens's Elevation of the Cross are evidence of Rubens's emulation of which Renaissance master?
Multiply.
(3x2 – 2x)(2x2 + 3x - 1)
O A. 6x4 + 5x3 - 9x2 - 2x
O B. 6x4 + 5x3 – 3x2 + 2x
O C. 6x4 + 5x3 - 9x2 + 2x
O D. 5x4 + 2x3 - 8x2 + 2x
Answer:
C
(3·x^2 - 2·x)·(2·x^2 + 3·x - 1)
= 3·x^2·2·x^2 + 3·x^2·3·x - 3·x^2·1 - 2·x·2·x^2 - 2·x·3·x + 2·x·1
= 6·x^4 + 9·x^3 - 3·x^2 - 4·x^3 - 6·x^2 + 2·x
= 6·x^4 + 5·x^3 - 9·x^2 + 2·x
