Answer:
Hypothesis: The commercial hair product Rogooti accelerates hair growth.Conclusion 1: Rogooti makes hair grow faster than it would normally do when using an ordinary product.Conclusion 2: Rogooti does not seem to have any effect on hair growth.Explanation:
A hypothesis is a scientific conjecture, not verified, that requires corroboration. It is a possibility, but not a fact.
A hypothesis must express what is expected to occur comprehensively. There must be a logical relation between variables. It must be objective.
To answer the question, Lisa might propose the following hypothesis, which needs to be corroborated.
Hypothesis: The commercial hair product Rogooti accelerates hair growth.
Experiment: Her family is a volunteer for the experiment, so all of them will use an ordinary hair product for a month. Before and after this period they will take notes of how long their hair is before and after the first part of the experiment. After this, they will cut down their hair to the initial length, and they will start using Ragooti for another month. After this last one, they will measure hair length again. Finally, Lisa will compare the initial length with the one after the first month and after the second month to analyze how Rogooti affects the speed of hair growth.
Result 1: When comparing lengths, Lisa will see that the hair of all her family members grew longer during the second month.
Conclusion 1: Rogooti makes hair grow faster than it would normally do when using an ordinary product.
Result 2: When comparing lengths, Lisa will not see any significant difference in the hair growth of her family during the first and the second month.
Conclusion 2: Rogooti does not seem to have any effect on hair growth.
How does DNA polymerase move along each strand of DNA?
A. Both move towards the replication fork
B. Both move away from the replication fork
C. One moves towards from the replication fork and the other moves away from it
D. There is only one DNA polymerase on the DNA at a time
Answer:
c i think
Explanation:
Answer:
B
Explanation:
This sort of replication, since it involves one nucleotide being placed right after another in a series, is called continuous. Whereas the DNA polymerase on the leading strand can simply follow the replication fork, because DNA polymerase must move in the 5' to 3' direction, on the lagging strand the enzyme must move away from the fork.

How have you heard the word metabolism used in daily conversation? How does this usage differ from the actual definition of metabolism?
Answer:
Metabolism - the chemical process within a living organism in order to maintain life
Explanation:
The common use it 'my metabolism is really slow/fast', usually heard in fitness and diet communities. The biggest difference is that, while metabolism does deal with the burning of energy from food, it really covers the processes using all materials such as water, food, nutrients, and oxygen in the cells to produce the body's energy.
Answer: Metabolism is often used in ads for exercise products or diet pills, which claim that they will boost metabolism to help people lose weight. In this context, metabolism is used only to describe weight loss or gain. This interpretation differs greatly from the actual definition of metabolism, which describes all the chemical reactions that occur within a cell.

Would you expect the entire crop grown from your preferred stalk to show the characteristics of the parent crop? Explain your answer.
Answer:
Over the ages the tendency of crop improvement efforts has been to select varieties with traits that give the highest return, largely by concentrating on genetic strains that combine the most desirable traits. The resulting homogeneity and uniformity can offer substantial advantages in both the quantity and quality of crop harvested, but this same genetic homogeneity can also reflect greater susceptibility or pathogens. Thus it appears the more that agricultural selection disturbs the natural balance in favor of variety uniformity over large areas, the more vulnerable such varieties are to losses from epidemics. The increased risks presented by genetic selection and the increased cultivation of only a few selected cultivars are easily perceived. Chapters 1 and 2 of this reports focus on crop vulnerability, because it is a broadly recognized problem. The issue of genetic vulnerability, however, is only one of several important problems affecting the management of global genetic resources.

What two functinol groups do amnio acids share
Answer: Amino acids are organic compounds (molecules) that contain amine (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid.
Explanation: The variation seen in naturally occurring amino acids arises from differences in this side chain.

why is active transport needed to take mineral ions into the cytoplasm of the root hair cell?
Answer: In plants, they need to move mineral ions from the soil into the roots. Mineral ions are more concentrated in the cytoplasm of plant cells than in soil water or dillute.
Explanation:
Minerals cannot be soaked up through osmosis since it only involves the movement of water. Because the minerals are in such low concentration, they cannot be absorbed through diffusion. Active transportation is used instead.
What is active transport?Active transport refers to the transport of molecules or ions into or out of a cell via the cell membrane, from a low concentration region to a high concentration region.
The particles use the energy released during respiration to move against the concentration gradient.
Active transport is defined as the movement of molecules against a gradient from a region of lower concentration to a region of higher concentration.
Active transport in plant root hairs allows plants to absorb mineral ions, which are required for healthy growth, even though the concentration of minerals in the soil is usually lower than in the root hair.
Thus, active transport is needed to take mineral ions into the cytoplasm of the root hair cell, as there is a need to move the minerals from the region of lower to higher concentration.

Where do chromosomal mutations begin?
Why do chromosomal mutations occur?
Answer:
A chromosome mutation is an unpredictable change that occurs in a chromosome. These changes are most often brought on by problems that occur during meiosis (division process of gametes) or by mutagens (chemicals, radiation, etc.).
Explanation:
Brainliest please?
Answer:
1) Different types of chromosome mutations can originate in the germinal cells.
2) Chromosome mutations are alterations occurring in chromosomes that typically result from errors during nuclear division or from mutagens. ... Abnormal chromosome numbers result from nondisjunction, or the failure of chromosomes to separate correctly during cell division.

Explain how mutations cause variation.
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
1. How do the gases necessary for photosynthesis and cellular respiration get into the leaf?
2. What is transpiration?
4. Deascribe the process of wound healing
Answer:
When the skin is injured, our body sets into motion an automatic series of events, often referred to as the “cascade of healing,” in order to repair the injured tissues. The cascade of healing is divided into these four overlapping phases: Hemostasis, Inflammatory, Proliferative, and Maturation.

Explain how water behaves in this reaction. Which definition of acids and bases would you apply? Upper subscript 2 upper C upper O subscript 3 plus upper H subscript 2 upper O right arrow upper H upper C upper O subscript 3 superscript minus plus upper H subscript 3 upper O superscript plus.
Answer:
Brownstead- Lowry base
Explanation:
A Brownstead- Lowry base accepts protons. If we look at this reaction, the water molecule accepted a proton to form its conjugate acid H3O^+.
Hence, in this particular instance, water behaved as a Brownstead- Lowry base in accordance with the definition of a Brownstead- Lowry bases.
Answer:
the correct answer is:
Explanation:
Water behaves as a base in this reaction.
The Bronsted-Lowry definition is applied because the reaction involves the transfer of H+ from one reactant to the other.
A Bronsted-Lowry base is defined as a substance that accepts a proton.
Because water gains a proton to form H3O+ in this particular reaction, it acts as a base.
