I Really Need Help On This One, A,B Or C.

Answers

Answer 1

Answer:

B

Explanation:

B makes the most sense of your answer choices

Answer 2

Answer:

A)

Explanation:

This is because the law of the conservation of energy states that energy can not be created or destroyed. This means that you can not get more energy than you put in, this could be from any energy store. In addition That also means that you will not be able to get less energy than you put in.

Although energy can not be created or destroyed some energy is lost to heat or friction, this would mean that the energy is not transferred to the idea store and so is lost to inefficiency . An example of this would be wind turbines, the wind would move the turbine using kinetic energy however some of the energy is lost to heat and friction

Select the living organisms that will decrease as a result of the loss of coral in the food web.

Answers

Answer:

Butterfly fish, Triggerfish, parrotfish, and sharks

Explanation: Because the first three fish listed feed on coral, their populations will decrease if coral is eliminated because that means there will be less food to go around for the populations to consume. Many will die out. If those fish die, there will be less of them for the sharks to eat, causing the shark population to decrease as well.

The pH of a solution determines the charge of certain R groups. The pH of pineapple fruit ranges from 3.5 to 5.2. Predict the effect on the activity of bromelain if it is used in a product with a pH of 11.

Answers

Answer:

The activity of Bromine will reduce

Explanation:

Bromine is found in pineapple stem with pH range of 3.5- 5.2 this implies that the environment where bromine is found is acidic hence when taken to a product whose pH is 11 which is basic then its performance will be low because its can only function well in an acidic medium.

pH ranges tell whether a substance is acidic, basic or neural.

Acid range from 3.5-6

7- neutral

8 above is basic

This is about knowing the behaviour of some elements in different PH Values.

The activity of bromelain will decrease in a product with a pH of 11. .

We are told that the PH of pineapple fruit is of the range of 3.5 - 5.2. In reality, this also includes it's stems and the plants as well. This falls into the acidic range because PH less than 7 is acidic.Now, these stems, plants and fruits of pineapple usually contain bromelain. This implies that bromelain does its' work in an acidic environment since pineapple has an acidic PH.

If bromelain is used in a product with a PH of 11, it means it is being used in a basic environment because a PH greater than 7 indicates a basic nature. This means bromelain will not function as well as it did in the acidic environment and as such the activity of bromelain here would decrease.

We can now conclude that the activity of bromelain will decrease in a product that has a PH of 11.
