As fall arrived, Steven saw that many homes had chrysanthemums planted in their flowerbeds. Their golden colors always signal the oncoming fall season.
Many plants respond to seasonal changes.

Why might a plant such as a chrysanthemum bloom during the fall?

a. the plant may be conditioned to live in a particular climate

b. the plant may be better suited to survive in cooler weather

c. the plant may be unable to adapt to cold weather

d. the plant may not respond to seasonal changes

Answers

Answer:

Explanation:

Plants such as chrysanthemum bloom during the fall because the plant might be conditioned to live in a particular climate. Thus, the correct option for this question is A.

What are the effects of seasonal changes on plants?

The effects of seasonal changes on plants might be determined by the fact that plants also adapt to the seasons if they live in a place that has strong seasons. Plants will shed their leaves during the winter if there isn't enough light, or shed their leaves during the dry season if there isn't enough water.

This response of flowerbeds through chrysanthemums represents the significance of seasonal change through which plants increases their survival. This is due to the conditional behavior shown by plants in order to facilitate their survival in the natural ecosystem.

Therefore, plants such as chrysanthemums bloom during the fall because the plant might be conditioned to live in a particular climate. Thus, the correct option for this question is A.

The data showed that recently the alligator population has decreased. How could the decrease in the alligator population affect the other populations? Be sure to explain whether the gar population, the diving duck population, and the crab population will change, and why.

Answers

Answer:

Since the alligator population decreased, this means there are less predators for the gar. Less predators for the gar mean the gar population will increase. More gar means more predators for the crabs, and therefore decrease the crab population. More gar also means more competition for the diving duck in terms of animals that eat crabs, and thus the diving duck population will also decrease.

Explanation:

To fully understand this question it is important to realize the relationship in this food web. It is important to note that the alligators will eat gar, the gar will eat crab, and the diving duck also eat carb. If the predator population decreases, then the amount of prey will be able to increase since there are less predators hunting them. If the predator population were to increase, there would be less prey, since more predators are hunting them.

The data showed the decrease in the population of alligator. The decrease in the population of alligator will increase the population of gar and, which will decrease the population of crabs, and it increases the competition between gar and diving duck.

What is the relationship between different animals?

All animals and plants are dependent on each other. In the given picture, the crabs, crocodiles, gar, and diving duck is given.

If there will be fewer crocodiles, the population of gar will increase that affects the population of crabs, because duck and gar both will eat the crabs.

Thus, the decrease in the population of alligator will increase the population of gar and, which will decrease the population of crabs, and it increases the competition between gar and diving duck.

How many centimeters can air pressure at sea level push a column of mercury up a tube?
1000 cm
30 cm
76 cm
360 cm

Answers

Answer: At sea level and at a temperature of 0° Celsius (C), the height of the mercury column is approximately 30 inches, or 76 centimeters. This represents a pressure of approximately 14.7 psia. The 30-inch column is used as a reference standard. Atmospheric pressure does not vary uniformly with altitude.

Since the atmospheric pressure at sea level is 760 millimeters of mercury, the dish of mercury would have to large enough to have enough mercury to allow the mercury to rise 760 millimeters up the tube (or 76cm)

Do large muscles occur naturally in some other living things? (List the living things and explain why you think these larger muscles occur naturally.)

Answers

Answer:

Yes, large muscles occur in some other living things. I think this because lets say you have a cheetah. Well, that cheetah runs very fast AND uses muscular endurances to hunt and chase its prey down. So yes, they start to devolp some large muscles. Some other living things that might have large muscles could be a bear, rhino, lion, tiger, or even a dog. As you can see, its more so the larger animals that devolp these large muscles.

There are three stages of the dragonfly life cycle, the egg, the nymph, and the adult dragonfly. Most of the life cycle of a dragonfly is lived out in the nymph stage

Life as an Aquatic Larva

Incomplete metamorphosis consists of the egg, the larva (nymph) and the adult. After the egg hatches, the free-crawling aquatic larva molts once and then starts hunting voraciously. As the larva grows, it will molt numerous times. Most dragonfly larvae mature to adulthood in one to three years. so maybe *(c.)

Byron goes rafting on the Colorado River. As he paddles along, he can see the erosion, weathering, and deposition caused by the river. Explain how a river is responsible for causing erosion, weathering, and deposition. Give an example of each.
P.s. no links or you will be reported

Answers

Answer:

Erosion by a river is caused by its capacity to curve out rocks and carry soil particles as sediments due to its erosion power. Rivers carve out rocks to form the pebbles you see in a river and also the rapids and cataracts.

A river contributes to the weathering of rocks such as limestone rocks. The water dissolves the calcium carbonate minerals in the limestone rocks making it brittle and easily crumble. Water also causes ferrous rocks to easily crumble due to turning of the iron minerals into rust.

rivers deposit their sediments when their velocity decreases. Deposits by rivers cause features like oxbow lakes and deltas that are observed at the mouth of rivers, where the slope gradient is very low.

How did the environment change? (PLEASE ANSWER ASAP!! I WILL AWARD BRAINLIEST) (image below)

1. You cannot tell how the environment changed. With each generation, more guppies passed on the gene for small spots to their offspring.

2. The rocks became smaller. With each generation, more guppies with small spots survived long enough to pass on the gene for small spots to their offspring.

3. The rocks became smaller. Guppies with small spots are more likely to survive, so the guppies with large spots changed to have small spots.

4.The rocks became smaller. Guppies with small spots are more likely to survive, so both kinds of guppies passed on the gene for small spots to their offspring.

Answers

Answer:

1.you cannot tell how the environment changed. with each generation, more guppies passed on the gene for small spots to their offspring.

Explanation:

the diagram doesn't show/say anything about the environment changing. it just shows that at time 1 there were an equal amount of guppies with small and large spots and then the second one had more guppies with small spots, meaning that they must've reproduced more and began to outweigh the guppies with large spots.

What was the carbon cycle on the prairie like?

Answer:

It stores more carbon below ground than a forest stores above.

Explanation:

Answer:

prairie plants

Explanation:

Roots of prairie plants are developed through centuries of growth. These deep roots will take the carbon out of the air add nutrients to the soil when they die, contributing to rich soil.

Prairie plants are especially adept at storing carbon, locking up large amounts in their roots. In fact, prairies store more carbon below ground than a forest stores above! Deep, complex prairie root systems sequester (store) carbon and – with the help of microorganisms – move it to the soil where it stabilizes.
