Five of the seed pots will receive a small amount of detergent in the soil and will be placed in the shade. The other five seed pots will not receive detergent and will be placed in the sun. All 10 seed pots will receive the same amount of water, the same number of seeds, and the same type of seeds. He allows the seeds to grow for two months and charts their growth every two days. What is wrong with his experiment

Division of prokaryotes is not called mitosis .why?
Answers
Answer:
gagvd
Explanation:
fuurryou
shhyuhgf
Answer:
The DNA of prokaryotes is not enclosed within a membrane, and is instead localized to a region called the nucleoid. This DNA acts as the prokaryote’s only chromosome, so the process of DNA replication is much quicker. After DNA replication, the original chromosome and its copy seperate. A cleavage furrow forms between the cell, the cell eventually pinches in half, and two identical daughter cells, each with an identical chromosome, are formed.

Provide a scientific explanation on how a mutation to the 17th nitrogen base of DNA leads to the formation of sickle cell hemoglobin protein instead of normal hemoglobin protein.
Answers
Answer:
Change in DNA leads to change in the structure of the cell.
Explanation:
Mutation in the 17th nitrogen base of DNA leads to the formation of sickle cell hemoglobin protein instead of normal hemoglobin protein because mutation is the sudden change that occur in the genes of a cell which change the genetic makeup of the cell. So when change occur in the DNA, a sickle cell is formed instead of normal hemoglobin. Normal hemoglobin only formed when the no change occur in the nitrogen base of DNA.

Answers
Answer:
Mitochondria.
Reactants of cellular respiration are glucose and oxygen.
Explanation:
Mitochondria is the location of cellular respiration where glucose is broken down in the presence of oxygen into energy in the form of ATP. When a glucose molecule is broken down with the help of oxygen, it produces energy, carbondioxide gas which is a waste material and water. There are three products of cellular respiration such as energy, carbondioxide and water. Energy is used by the organism in different activities while carbondioxide gas and water are removed from body through breathing. Using of glucose by mitochondria and converted into energy in the form of ATP is the energy flow.
This evolutionary tree shows the influence of speciation and extinction on the diversity of life. After 2 million years, lineage A had a(n) ________ rate of extinction and ________ speciation rates compared to lineage B.
Answers
Answer:
Lower; higher
Explanation: Speciation is a term used to describe the formation of new, distinct and diverse set of characters and organism as evolution occurs in lineages of an organism.
The higher the number of lineages the higher the number of diverse characters and features. That is what makes the speciation to be lower in the chances of extinction to be higher as the lineages Increase from lineage 1 to lineage 2.

Explain the role of a hypothesis in a scientific investigation.
Answer:
Short answer please quick
Answers
Answer:
A hypothesis is a testable proposition
used to explain scientific phenomena. It
may be based on previous observations
(a sort of educated guess) or it may
simply be a hunch. Most scientific
hypotheses are combinations of
observation and intuition. The important
thing is that the hypothesis be testable.
If the hypothesis is disproved through
testing, then it is discarded and a new
hypothesis is proposed. If the hypothesis
stands up to rigorous testing, then our
faith in the hypothesis is increased.
This system of careful, rigorous, and
unbiased testing of a hypothesis is what
characterizes the scientific method.
