The hypothesis is the part of the scientific method that is the supposition based on some observed data. In Hanna's experiment, "caffeine increase the heart rate of the water flea" is the hypothesis. Thus, option C is correct.
What is a hypothesis?The hypothesis has been defined as the conjecture that is proposed in a scientific method and is based on the speculations from the observed facts and information. It is proposed to perform the experiment and reach the conclusion of the reliability.
They are testable and are performed through the experimental design that includes the experimental and control group so that the collected evidence can be analyzed and proved to be true. In Hanna's experiment, the effect of caffeine on the heart rate of fleas is a hypothesis.
It is a hypothesis as it is based on the observed fact that caffeine increases the human heart rate. The caffeine acted as the independent variable and the heartbeat was the dependent variable that showed that water fleas have increased heartbeat if given caffeine.
Therefore, option C. caffeine increases heartbeat is the hypothesis.

C. A prokaryotic cell does not genetic material
Answer:
Your answer is Option B
hope this helped you
please mark as the brainliest (ㆁωㆁ)
Answer:
B, in the cytoplasm
Explanation:
Most prokaryotes carry a small amount of genetic material in the form of a single molecule, or chromosome, of circular DNA. The DNA in prokaryotes is contained in a central area of the cell called the nucleoid, which is not surrounded by a nuclear membrane. This question is worded quite strangely, as the nucleus is an organelle it would make better sense to say in the organelles but it refers to organelles as plural and it's not in any other organelle but the nucleus, the cytoplasm is what surrounds the organelles and has direct contact with the cell membrane, the nucleoid also does not contain any enclosing membrane

Explanation:
There are many characteristics of life, including, cells. A cell is a tiny unit of life that carries out many different processes.
If something is considered living, it must have at least one cell, but it can have more. For example, bacteria is unicellular and living. We (humans) are also living, but made of billions of cells.
Therefore, for something to be considered living, it must be composed of at least one cell.

8 incisors. 4 canines, also called cuspids. 8 premolars, also called bicuspids. 12 molars, including 4 wisdom teeth.
Human: deciduous teeth: 212/212; adult = 2123/2123. Both childhood molars are replaced by adult premolars. Adult total is double the formula = 32. Opossum: 5134/4134 (one less incisor on each side of the lower jaw).
HOPE THIS HELPED
[tex]\huge\bold\red{Answer:-}[/tex]
The dental formula represents the arrangement of teeth in each half of the upper and the lower jaw. The entire formula is multiplied by two to represent the total number of teeth.
The dental formula for milk teeth in humans is:
[tex] \frac{2102}{2102} = 2[/tex]
Each half of the upper jaw and the lower jaw has 2 incisors, 1 canine, and 2 molars. Premolars are absent in milk teeth hence the zero.
The dental formula for permanent teeth in humans is:
[tex] \frac{2123}{2123} = 32[/tex]
Each half of the upper jaw and the lower jaw has 2 incisors, 1 canine, 2 premolars, and 3 molars. An adult human has 32 permanent teeth.

During which phase does the cell actually separate into two individual daughter cells?
Answer:
During which phase does the cell actually separate into two individual daughter cells? Explanation: Cytokinesis is the phase during which the cytoplasm of the cell divides and the cell actually separates into two cells. The term cytokinesis actually means cutting (kinesis) of the cytoplasm.

What is cytokinesis?Cytokinesis is the process in which the cytoplasm of a cell divides following the division of the nucleus.
Mitosis is the biological process by which living cells replicate themselves and create offsprings.
Mitosis primarily involves the division of the nucleus while Cytokinesis is the division of parent cells into daughter cells.
Therefore, the parent cell separates into two individual daughter cells in the cytokinesis phase of mitosis.

why do all organisms share the same genetic code?
Answer:
DNA is considered a universal genetic code because every known living organism has genes made of DNA. ... All organisms also use DNA to transcribe RNA, and then they translate that RNA into proteins. Every living organism uses that same system. Basically, every three pieces of DNA becomes one amino acid.
Explanation:
because it is
