QUICK ASAP PLS Certain bacteria live and grow on the roots of some plants and produce chemicals that are beneficial to the plants. Which of the following observations best supports the claim that this relationship is beneficial to the plants?



Group of answer choices

Plants with a higher amount of the bacteria on their roots have increased rates of survival and reproduction.

When the bacteria are removed from the plant roots and are grown in a laboratory setting, they fail to survive.

The population size of the bacteria varies greatly depending on the chemistry of the soil and the type of the plant.

The chemical produced by the bacteria can be created by humans and added to the soil where it reaches the roots of the plant.

Answer:

Explanation: Plants with a higher amount of the bacteria on their roots have increased rates of survival and reproduction.

Read the following scenario to answer this question:[/HTML]Mike loves to cook. He heard that if you add salt to water, it will boil faster. If it’s true, it could save him a lot of time in the kitchen. He decided to perform an experiment to test this hypothesis. He set up three pots, each containing three liters of water. In the first pot, he didn’t add any salt; in the second pot, he added one tablespoon of salt; and in the third pot, he added two tablespoons of salt. He got out his stop watch and turned the stove on under all three of the pots.Is there a control group, and if so, what is it? ____________________

1. What is the function of a top predator in an ecosystem?

A. It increases the food for other predator species.

B. It creates imbalance in the ecosystem.

C. It maintains populations. **

D. It helps increase the number of prey.

Reason - The answer is C because predators couldn't possibly increase the food for other predators. They obviously don't imbalance the ecosystem since they help keep it cycling. And they can't increase the number of prey if they're eating prey so therfore you're left with C.

2. Which is considered a top predator in the ocean?

A. A shark**

B. A sea lion

C. A small whale

D. A bird.

Reason - The answer is A because actually the top predator in the ocean is the killer whale but since it's not an option, you'd wanna go for a shark. A small whale obviously couldn't eat a big shark, nor could any of the others. :)

3. What happens to an ecosystem during normal seasonal flooding?

A. The biodiversity of the area reaches equilibrium.

B. The biodiversity of the area increases. **

C. The biodiversity of the area decreases.

D. The biodiversity of the area stays the same.

Reason - Just trust, I'm trying to finish this post and got tired of giving reasons. Sorry and thanks:)

4. How is the impact of seasonal flooding different from damming a river?

A. Seasonal flooding helps balance biodiversity, but damming does not.

B. Seasonal flooding is not considered an ecological disturbance like damming.

C. Seasonal flooding does not impact biodiversity for as long term as damming.**

D. Seasonal flooding increases biodiversity, but damming does not.

Reason - Again, trying to finish this and tired of typing reasons but the answer is indeed C because damming a river can causes long-term damage to biodiversity and the ecosystem while it can quickly recover from a flood because it doesn't really damage as much and the flood will simply be gone after a bit. :)

5. Would a long-term increase in the average temperature of a region be considered a significant disturbance in the ecosystem?

A. No, because it would not create large-scale changes in the environment.

B. No, because increases and decreases in average temperatures are normal.

C. Yes, because such a change could have a large-scale impact on wildlife. **

D. Yes, because any slight change in temperature is considered a distribution.

Reason - Eh.. it's pretty self explanatory. ​
