What is an experiment?

An experiment is a test conducted under controlled conditions made to either demonstrate a known truth, examine the validity of a hypothesis, or determine the efficacy of something previously untried.

According to this question, a group of students decides to investigate the loss of chlorophyll in autumn leaves. They collect green leaves and leaves that have turned color from sugar maple, sweet gum, beech, and aspen trees and subject them to analysis to determine their chlorophyll content.

However, it is important to replicate this experiment because it can only be accepted by scholarly societies if the findings are replicable.

Therefore, the students would be advised to replicate their experiment because the findings won't be accepted until it is replicable.

Is the widely accepted scientific theory that characteristics of a population may change over time, and that current species may gradually give rise to new species.

Answers

Answer:

Evolution theory

Explanation:

The evolution theory was developed by Darwin and it is a generally accepted theory that deals with gradual changes in the characteristics of organisms due to their quests to adapt to continuous changes in the environment.

As the environment of organisms keeps changing, the population of the organism keeps adjusting. Individuals that are able to adjust to the changes survive and are able to reproduce while the weak ones gradually die off from the population.

Hence, the entire characteristics of the population is changed with time as a result. The continuous changes sometimes lead to some species within the population giving rise to a new species entirely.

D.) Some enzymes break down into ions.

Answers

Answer:

Your answer is B

Explanation:

Ions play an important role in the metabolism of all organisms as reflected by the wide variety of chemical reactions in which they take part.

Ions are important to metabolism because some enzymes require specific ions to work. Thus, the correct option is B.

What is Metabolism?

Metabolism may be defined as a set of methodologies that involves gradual and continuous chemical alterations that take place inside the cell or the body of an individual in order to stimulate the rate of survival.

Metabolism is also characterized as the sum of the chemical reactions that occurs within each cell of a living organism in order to furnish energy for vital processes.

Ions are an inorganic form of molecules that are loosely associated with the enzyme in order to ensure its effective function. Ions like [tex]Na^+, Mg^2^+, Ca^2^+[/tex], etc. are most prevalent.

Therefore, ions are important to metabolism because some enzymes require specific ions to work. Thus, the correct option is B.

In a small population of Brazilian natives, the frequency of gene p, responsible for this disease, is 0.3. What must be the frequency of people who are heterozygous for this disease?

Answers

Answer:

Explanation:

According to hardy weinberg

p+q=1

p2+2pq+q2=1

p stands for the dominant genotype

q stands for recessive genotype

pq stands for population that are not homogenous i.e not the same

Given that p=0.3

P2=0.09

q=1-0.3= 0.7

q2=0.49

2pq= 2×0.3×0.7

=0.42

Therefore, the frequency of heterozygous population is 0.42

p2+2pq+q2

0.09+0.42+0.49 = 1

One app, CalmDown, appeared to be promising. It didn't have any reviews yet and looked to be a brand-new app, so he decided to try it out. He downloaded the app to his phone and opened it up. The first screen required he enter in his name and email address. At the very bottom of the screen it had some small writing, but Marcus didn't notice it and hit the continue button.Had Marcus clicked on the link at the bottom of the screen, he would have seen the following:The second screen stated "Three-day trial version- Free! $59.99 annual fee thereafter." Marcus was annoyed that the app would cost him almost $60 but figured he would set a reminder on his phone to cancel the app before the trial period expired so he wouldn't get charged. Plus, he wanted to see the app in action. If it was actually worth the price, he wouldn't mind paying the annual fee. He clicked "Continue" and put in his bank card information on the next screen. The following screen asked Marcus a series of questions about his stress level and what he felt caused stress in his life. He clicked "high" and "work" as the level and cause. He then completed the first CalmDown meditation in the app, but was not impressed with its functionality. Deciding he would cancel his subscription immediately, he went into the profile settings to try to find the cancel option but couldn't. He searched every possible place on the app but didn't see a way to cancel the subscription. Marcus decided to try to find the app's developer through their website, but a quick search didn't turn up anything. Already stressed and becoming more frustrated, Marcus decided to contact the app store. They informed him that he should be able to go into his app store account and cancel the subscription there. However, when Marcus went there, he didn't see the app as an option or as a subscription. Thinking that maybe his subscription didn't process, he just deleted the app from his phone.Marcus didn't give the app or the subscription any more thought, becoming increasingly more distracted by the amount of stress at work. Four months later, Marcus was looking at his bank account online and noticed it was lower than it should have been. He began reviewing the charges and noticed multiple charges for $59.99 to a merchant named "CDgotU." He immediately remembered the app and contacted his bank to dispute the charges. His bank replied that due to the charges being debit withdraws he needed to dispute them within 2 days of being made. Moreover, if he had been diligent about watching his account, they could have put a block on the account and the remaining fraudulent charges would have been prevented. The bank representative also told him that he should try to get a refund from the company that charged him. After making his case with the bank representative for several hours about how he tried to cancel his subscription, he was unsuccessful. The bank's representative was able to provide Marcus a phone number attached to the Merchant account, but when Marcus called the number it was disconnected. The bank could not provide him with any additional information such as a company address or website.After more internet searching, Marcus saw a number of other complaints online about the app, and noticed it had been removed from the app store and was no longer available for download. Marcus decided to bring an action against the company for fraud, breach of contract, conversion, and several other claims in his home state of Vermont.Can Marcus compel the bank or the app store to provide additional information about the creator of CalmDown in order to determine the creator's location and potential assets?a. No, these records are not subject to being subpoenaed due to their confidential nature. b. Yes, he can subpoena records during the discovery process from both, but the bank and the app store may ask the judge to deny the request or limit the request due to privacy concerns. c. Yes, but he must subpoena these records prior to the filing of the complaint. d. Yes, he can file interrogatories during the discovery process to both the bank and the app store.
