Hello. You have not submitted the experiments to which this question refers, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.
A dependent variable is one that is influenced by an element, in order to present a result, that is, it is a variable that does not establish itself, being dependent on another variable to establish itself. An example of a dependent variable can be seen in an experiment that seeks to determine the differences in growth rates of bean plants that were fertilized with different organic fertilizers. As you can see, this is an experiment where the different organic fertilizers influence differences in the growth rate of bean plants. Thus, the growth of these plants depends on the fertilizer, this growth being the variable dependent on the experiment.
A control group, in turn, is an element of the experiment that does not receive the element that is being tested in the same experiment. The control group is important, because it allows the researcher to see the results of a system where the tested element does not exist, thus being able to determine the real differences that the tested element is capable of causing. Using the same example presented in the paragraph above, we can see that the different organic fertilizers are the elements tested in the experiment. These fertilizers will be applied to the plants, however it is important that at least one of these plants does not receive any fertilizer, so that the difference between a system with fertilizer and a system without fertilizer can be evaluated. This plant that received no fertilizer is the control group.

Which two compounds are always together?
a. Oxygen and Water
b. Carbon Dioxide and Glucose
C. Oxygen and Glucose
d. Carbon Dioxide and Solar
Answer:
a. Oxygen and Water
Explanation:
Oxygen and water are a pair and they come together. This is proven by the equation for water which is H2O which contains oxygen.
Oxygen and water compounds are always together. So, the correct option is A.
What are Compounds?A compound is a substance made up of two or more components which are chemically combined in a certain ratio. Chemical bonds hold the elements in a compound together. These bonds can be covalent, ionic, or metallic, according to the characteristics of the elements involved.
Because oxygen is a fundamental component of molecules of water, which have a chemical formula H2O, oxygen and water are frequently found together in nature. Water is required for life as well as many biochemical activities, while oxygen is required for respiration in many species. As a result, oxygen and water are frequently found combined in natural habitats.
Therefore, the correct option is A.

What is Big Bang Theory ?The Big Bang theory is an attempt to explain what happened at the beginning of our universe. Major discoveries in Astronomy and Physics have explained that our universe actually had a beginning. Before that moment there was nothing and after that jump there was something which is our universe.
According to the widely known theory, our universe sprang into existence as "singularity" which goes back around 13.7 billion years ago. Singularities are basically zones which flout our knowledge of physics. They are assumed to be present at the core of "black holes."
Black holes are regions of enormous gravitational pressure. The pressure is assumed to be so extreme that finite matter is actually squished into infinite density (a mathematical concept which truly boggles the mind). These zones of interminable density are called "singularities."
Thus, everything in the universe was created when the big bang occurred and the universe is expanding. So, the correct option is (A).

How are ferns, gymnosperms, and angiosperms alike? They are all vascular plants. They depend on water for fertilization. They all produce seeds. Reproduction depends on birds, bees, and other animals.
Answer:
The correct answer is ''They are all vascular plants''.
Explanation:
Vascular plants or tracheophytes are those organisms of a more evolved plant nature, they are those that have leaves, stem and roots and that have a vascular system formed by conducting vessels. Ferns are pteridophytic vascular plants, they do not produce flowers or seeds and are mostly herbaceous. All those vascular plants that have seeds but do not have flowers are called gymnosperms. The seeds are not covered or protected by an ovary, so they appear visible on the leaves or other parts of the plant. Angiosperms are plants with flowers, whose seeds develop within the ovary, which grows and becomes fruit.

they all vascular plants

Changes in ____ result in a change in protein structure which alters the ____-type of the organism and MIGHT increase _____.
Answer:
DNA, genotype and resistance.
Explanation:
Change in DNA of an organism results in a change in the shape and structure of protein because DNA has the codes of instructions on the basis of which ribosomes synthesis proteins for the cell. This change occurs due to mutation in the DNA sequence that causes change in protein. Due to this mutation, the genotype of an organism changes and might increases its resistance that leads to its survival in that environment so we can say that mutation has good effects on the organisms.

Why the Chimpanzee's diploid number is 24 instead of 48.
I am not sure if the following table supposes me to write 2 (N) on here...
Thank you very much
Answer:
It has 24 pairs and 48 number of chromosomes.
Explanation:
The Chimpanzee's diploid number of chromosome is 24 pairs instead of 48 because of the resemblance with the human cell that have 23 pairs of chromosome. The Chimpanzee has 24 pairs of chromosome or another words we can say that chimpanzee has 48 number of chromosomes not pairs. Humans have 23 pairs whereas apes have 24 pairs of chromosome. The theory suggested about this close number of chromosomes is that at some point two ape chromosomes fused to make a single human one.

Explanation:
Natural selection is sometimes described as "survival of the fittest." Four friends were arguing about what the phrase "survival of the fittest" means. This is what they said: Diya: "I think ‘fit' means bigger and stronger." Ayush: "I think ‘fit' means more likely to reproduce." Daniel: "I think ‘fit' means being able to run faster." Hari: "I think ‘fit' means more intelligent."
Answer:
Ayush is correct.
Ayush: "I think ‘fit' means more likely to reproduce
Explanation:
Survival of the fittest simply means when organisms living in an environment develop traits or characteristics that help them to fully adapt to the environmental conditions and are able to survive, reproduce and pass on traits to their next generations. It's an indication that the organisms posses some characteristics that can help them to survive and reproduce in unfavorable environmental conditions.
