A. Which plants did humans grow at this site and how were they grown?

B. How have humans impacted the rock layer of the city changed over time?

C. What tools were found at the site and which civilization used them?

D. How did changes in the depth of the river affect the houses people built at the site?

4. Insects are important to many ecosystems. For example, bees help pollinate many different plants and many animals rely on insects as food sources.

5. Coral bleaching occurs when coral become stressed and expel the algae that they contain. According to scientists, what steps can society take to fix coral bleaching?(1 point)

A. Scientists have concluded that society can only fix coral bleaching by stopping climate change entirely.

B. Scientists have concluded that society can fix coral bleaching by reducing stressors, such as sedimentation and pollution, and limiting climate change.

C. Scientists have concluded that society can fix coral bleaching by reducing stressors, such as sedimentation and pollution.

Answer:

(Q1: B)

(Q2:B)

(Q3:C)

(Q4:D)

(Q5:B)

Explanation:

Question 1:

A consensus hears all voices in a group and goes with the common "majority rule" and B shows this in clear detail.

Question 2:

They both have different skill sets but we can remove option A because all fossils are handled the same way. We can remove D because it doesn't make sense for the question which leaves us with C and B. This makes us know that the answer is B because it makes the most sense for the question.

Question 3:

An anthropologist is someone who specializes in the study of human societies and cultures and their development and an archaeologist is someone who digs up fossils. The only answer that makes sense here is C because the archaeologist can uncover the tools and where they made marks in the rock while an anthropologist can use those to discover what civilization it was and how those tools were used.

Question 4:

In the context of this question we can decide that the only relevant answer is D because it would watch over a period of time that could show climate change while the others are just simple facts that can be uncovered about the daily life of these insects.

Question 5:

The steps that can be taken to fix coral bleaching are to reduce stressors, such as sedimentation and pollution, and limiting climate change. This is because the main things that cause the coral to become bleached are changes in the temperature and salinity of the water. By polluting the ocean we change the chemical formula of the water and therefore affect the coral and the climate change heats the ocean to temperatures that the coral can't or will not be able to withstand.

Question
Use the text to identify the sentences with evidence that matches the claim.

Claim 1 --> Tropical rainforests contain more biodiversity than all other biomes.

1) Biodiversity refers to the total number of different species of all kinds living in an area.

2) Tropical rainforests have many of the climate characteristics that organisms of different species need to grow, such as warm temperatures, plenty of rain, and many food sources.

3) There are large amounts of daily sunlight, which provides a great deal of energy to a variety of rainforest organisms.

4) Surprisingly, rain forest soil is very poor.

5) Due to the large amounts of rainfall, nutrients are leached out of the soil quickly.

6) Warm temperatures cause dead organisms to decay quickly, and the nutrients are then used by many different plants.

Two decades after the Emerald River Dam was built, none of the eight fish species native to the Emerald River was still reproducing adequately in the river below the dam. Since the dam reduced the annual range of water temperature in the river below the dam from 50 degrees to 6 degrees, scientists have hypothesized that sharply rising water temperatures must be involved in signaling the native species to begin the reproductive cycle.

Which of the following statements, if true, would most strengthen the scientists’ hypothesis?
(A) The native fish species were still able to reproduce only in side streams of the river below the dam where the annual temperature range remains approximately 50 degrees.
(B) Before the dam was built, the Emerald River annually overflowed its banks, creating backwaters that were critical breeding areas for the native species of fish.
(C) The lowest recorded temperature of the Emerald River before the dam was built was 34 degrees, whereas the lowest recorded temperature of the river after the dam was built has been 43 degrees.
(D) Nonnative species of fish, introduced into the Emerald River after the dam was built, have begun competing with the declining native fish species for food and space.
(E) Five of the fish species native to the Emerald River are not native to any other river in North America.

Which of these does not affect an individual’s metabolic rate?

A-their height

B-The genes they inherited
