Answer:
The correct option is C: "Oxygen levels would be higher, but carbon dioxide levels would be the same".
Explanation:
The sealed aquarium is paced near a window which means they have access to sunlight, and hence, can photosynthesize. As the plants use up carbon dioxide during the day and give out oxygen during this process, they also respire during the night, a product of which is carbon dioxide. This is why the levels of carbon dioxide will remain the same and level of oxygen will rise because they are photosynthesizing for a longer period during the day than they are respiring during the night.
Hope that answers the question, have a great day!
Answer:
The correct answer is A.) Sister chromatids are pulled apart.
Explanation:
This is because during Anaphase II in Meiosis, the sister chromatids are pulled apart.
Chromosome pairs line up during Prophase I. <em>Not B.</em> When the chromosome pairs pair up this is also Metaphase I. <em>Not C.</em> When chromosome pairs are pulled apart, Anaphase I is occurring.

The carbon cycle describes the way the element carbon moves between the Earth's biosphere, hydrosphere, atmosphere, and geosphere. It is important for a few reasons: Carbon is an essential element for all life, so understanding how it moves helps us to understand biological processes and factors that influence them.

The answers would be:
Genotype Phenotype
Tt Tall stemmed
tt Short stemmed
Genotypic ratio : 2:2 or 1:1
Phenotypic ratio: 2:2 or 1:1
<u />
<u>You can read on to see how this was done:</u>
Tall stems (T) are dominant to short stems (t).
First figure out the genotypes of the parents. We have a short-stemmed plant and a heterozygous long-stemmed plant cross.
For short stem to occur, you need 2 pairs of short alleles. So the first parent would have a genotype of tt.
Heterozygous long-stemmed means that the parent has one of each allele. So the genotype of the second parent would be, Tt.
Now we can make our Punnett Square.
tt x Tt
<u> t t </u>
<u>T | Tt | Tt</u>
<u>t | tt | tt</u>
Let's list down the genotypes and phenotypic results.
Genotype no. Phenotype
Tt 2 Tall stemmed
tt 2 Short stemmed
So from that we can answer the other questions:
Genotypic ratio : 2:2 or 1:1
Phenotypic ratio: 2:2 or 1:1
One hypothesis can be that there is an effect of aeration on the growth of roots of bean seedlings.
Control group: has "no aeration"
Experimental group: has the aeration treatment
Dependent variable: growth can be measured in the length of the seedlings probably in centimeters
Researching is composed of various explorations in utilizing the scientific method in the process. It also, answers any scientific inquiry with the use of scientific method. Research enables and promotes the scientific community at a larger scale. Contributing and collaborating knowledge all-over the people and persons in science. Researches play a big role in everyone’s academic identity because
<span>1. It actively makes the individual scientific in approach to things of curiosity and makes him/her use the knowledge to study and produce results which</span> <span>
2. The scientific society will benefit by this particular study and can work together to better explore and discover. </span><span> </span>
