Many people install solar panels on the roofs of their homes. They can control the angle of the panels so to receive the most amount of sunlight. How might someone adjust the angle of their solar panels during the summer and winter differently, so
to maximize the amount of solar energy they collect?

Answers

Answer:

(check the explanation)

Explanation:

During summers, sunrays hit the surface of the earth at an almost perfectly vertical angle. Therefore, in summers it is best to adjust the angle of the solar panels to be vertical to maximize the amount of solar energy collected.

During winters, the sunrays hit the surface of the earth at a slanted angle. Therefore, the solar panels should be adjusted at a slanted angle to maximize the amount of solar energy collected.

Scientists found a layer of rock with several different fossils in it, as shown in the image. Based on the model, which of these fossils are the oldest and which are the newest? Explain your answer.

Answers

wouldn’t the bottom be the oldest?

Answer:

The oldest is section A, and the newest is section B.

Explanation:

First of all, the bottom most layer is almost always the oldest, because when rocks form, they don't go "hey lemme form under you", they form on top.

Second, bottom most layer is has the simplest fossils and the fossils are the same. You can see that as the higher section you go, the fossils are more complex and have more variety. Which is because of evolution.

Third, I don't know if this counts, but the bottom has the least color so I'm guessing that means that it has been decaying and whatever else you wanna call it than the other layers. Whereas the top is the most colorful, in my opinion.

C is correct I think

Explanation:

A: Couldn't be because there is one less source that is consuming the algae, so algae wouldn't decrease

B: Number of pike wouldn't increase because it would be getting less food

C is correct because there would be less pike because there would be less food for them, so fishermen would catch less

D: Same explanation as B but for Dragonfly larvae

I’m thinking it C it seems like the best answer because without the larvae there would be less perch which they eat so with the decrease in perch there is less for pike to eat so more pike would die from hunger so there would be less pike for the fisherman.

Look at the diagram of the rock cycle below.

Which part of the cycle is missing?
A.
sedimentation
B.
melting
C.
crystallization
D.
mineral integration

Answers

answer B.

it’s melting

From the diagram of the rock cycle the missing part is ( B ) ; Melting

Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.

Magma is released to the earth surfaces during volcanoes therefore the missing term  in the rock cycle is melting

Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.

Red Grouper
Catch Year Average Mass (kg) Mature Males Estimated Population (millions)
1990 22.3 17.5
1991 21.6 18.2

1993 20.9 13.5

1997 19.8 10.8
1998 18.8 9.5
1999 17.9 9.4

This chart shows the annual catch statistics for the red grouper for the state of North Carolina during the 1990’s. Red grouper begin their lives as females, and the largest fish change sexes to become male during mating season. Only large females mate with these males and lay eggs.

You are a fisheries biologist for the state of North Carolina. You are charged with protecting the fish population, while also keeping professional fishermen from losing their jobs. Based on the chart above, what would you conclude and what would your solution be?

A) There is a serious problem with overfishing of red grouper, so there must be a problem with other fish as well. All fishing for any species should be banned.
B) There is not a very serious problem. The smaller size and population are probably just due to some bad years. Do nothing and monitor the situation.
C) There is a problem with overfishing. Ban fishing for large fish so their size and population can recover, but allow the fishermen to take smaller fish.
D) There is a problem with overfishing of red grouper, but the fishermen need to stay in business. Bring in another species of grouper from Australia, so that there are more fish to catch.

Answer: C

Explanation: There will still be fish left, you don't want to take Australia's fish, because then they will keep needing more
