Experiment 5

Lisa is working on a science project. Her task is to answer the question:

"Does Rogooti (which is a commercial hair product) affect the speed of hair growth"? Her

family is willing to volunteer for the experiment.

1. Identify the hypothesis in this experiment.

2. State a conclusion to support your hypothesis. 3. State a conclusion that refutes the hypothesis.

Answers

Answer 1

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

Answers

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?

Answers

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.​

Answers

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.

why is active transport needed to take mineral ions into the cytoplasm of the root hair cell?

Answers

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.

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.

He stood for a moment, his lean, drawn face haggard in the light of the two hurtling moons.He looked hopelessly across the dark spaceport. It was a large one, for this ancient town of Syrtis was the main port of Mars. The forked light of the flying moons showed many ships docked on the tarmaca big liner, several freighters, a small, shining cruiser and other small craft. And for lack of one of those ships, his hopes were ruined!A squat, brawny figure in shapeless space-jacket came to Kenniston's side. It was Holk Or, the Jovian who had been waiting for him."What luck?" asked the Jovian in a rumbling whisper."It's hopeless," Kenniston answered heavily. "There isn't a small cruiser to be had at any price. The meteor-miners buy up all small ships here.""The devil!" muttered Holk Or, dismayed. "What are we going to do? Go on to Earth and get a cruiser there?""We can't do that," Kenniston answered. "You know we've got to get back to that asteroid within two weeks. We've got to get a ship here."Desperation made Kenniston's voice taut. His lean, hard face was bleak with knowledge of disastrous failure.The big Jovian scratched his head. In the shifting moonlight his battered green face expressed ignorant perplexity as he stared across the busy spaceport."That shiny little cruiser there would be just the thing," Holk Or muttered, looking at the gleaming, torpedo-shaped craft nearby. "It would hold all the stuff we've got to take; and with robot controls we two could run it.""We haven't a chance to get that craft," Kenniston told him. "I found out that it's under charter to a bunch of rich Earth youngsters who came out here in it for a pleasure cruise. A girl named Loring, heiress to Loring Radium, is the head of the party."The Jovian swore. "Just the ship we need, and a lot of spoiled kids are using it for thrill-hunting!"Kenniston had an idea. "It might be," he said slowly, "that they're tired of the cruise by this time and would sell us the craft. I think I'll go up to the Terra Hotel and see this Loring girl.""Sure, let's try it anyway," Holk Or agreed.With the Jovian clumping along beside him, Kenniston made his way from the spaceport across the ancient Martian city.Read the following lines from the text:And for lack of one of those ships, his hopes were ruined!This line suggests Kenniston isdesperate angry dramatic realistic In developing its future strategy, CVS is focusing on Amazon, which is expanding into the healthcare business.
