Answers

Answer:

The correct option is a: "Adds to existing knowledge"

Explanation:

A hypothesis is an idea that is brought forth based on an observation. It needs to be tested by carefully and thoroughly planning an experimental design that either supports or refutes the hypothesis. So even if it comes out to be incorrect, it still allows us to understand some aspect of a phenomenon that was unknown till then.

Carbon is defined as a chemical element, like hydrogen, oxygen, lead or any other element that is very abundant in the periodic table. It exists in pure or nearly pure forms such as diamond and graphite, but can also combine with other elements to form molecules.

Carbon is used in metal smelting in the form of charcoal (from wood) and coke (from coal) as impure carbon, which is particularly important in the iron and steel industries. Graphite is used in pencils, to make brushes in electric motors, and in furnace linings, while activated charcoal is used for purification and filtration.

When we burn we the human fossils, some gases like Carbon is released into the atmosphere.

Thus, Carbon is released into the atmosphere. So, the correct option is (A).

Dog breeders maintain the purity of breeds by keeping dogs of different breeds apart when they are fertile. This kind of isolation is most similar to which of the following reproductive isolating mechanisms? a. temporal isolation b. behavioral isolation c. habitat isolation d. gamete isolation

Answers

i believe the answer is habitat isolation! hope this helped :)

The isolation practiced by dog breeders to maintain the purity of breeds is most similar to behavioral isolation

 (option b). is correct.

How do we explain?

Behavioral isolation is a reproductive isolating mechanism in which individuals of different species or populations have different behaviors or mating rituals that prevent them from successfully mating with each other. In the case of dog breeders, they keep dogs of different breeds apart during their fertile periods to prevent them from mating and producing mixed-breed offspring.

This behavioral isolation helps to maintain the purity of the specific breeds.

Therefore,  (option b). is correct.

What is the product of (-0.9)(-2.4) SCENARIO:Marcus, feeling stressed out from work, decided to search for a meditation app for his phone that would help him relax during the day. 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.
