Why was Alfred Wegner's theory of continental drift not widely accepted by the scientific community at first?

A
He had no evidence to support it.

B
The continents were not moving at that time.

C
The shape of the continents did not match up.

D
He could not explain how the continents move.

Answers

Answer 1
I think it’s B but I’m not 100% sure, The main reason that Wegener's hypothesis was not accepted was because he suggested no mechanism for moving the continents. He thought the force of Earth's spin was sufficient to cause continents to move, but geologists knew that rocks are too strong for this to be true.

Answer 2
It’s d because he couldn’t explain what made the continents move

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.

Explanation:

tdlr-  internal environmental factor, genes, hormones

The image shows an example of an external environment affecting her fish's growth. Other conditions that could affect animal growth include internal environment.

What is environment?

An organism's or an ecological community's environment is the collection of physical, chemical, and biological variables that affect it and ultimately decide its form and survival.

Everything in our environment affects us. Whether they are living or not is up to you. It consists of natural forces such as chemical and physical ones.

Environments are where living things exist. They are continually interacting with it and modifying their behavior to fit the circumstances.

Clean air and water, rich land for growing food, as well as energy and material inputs for production, are all provided by good natural surroundings.

The picture demonstrates how an outside environment can effect a fish's growth. Internal environment is another factor that might influence an animal's growth.

Thus, this can be the complete scenario for the gold fish.

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)

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.

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.

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:

A

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.

C. Cells are living and the organelles that make them up are nonliving.

D. Cells are nonliving and the organelles that make them up are also nonliving.

Answers

Answer:

I love science here's a explanation of all of your choices

Explanation:

An organelle (think of it as a cell's internal organ) is a membrane bound structure found within a cell. Just like cells have membranes to hold everything in, these mini-organs are also bound in a double layer of phospholipids to insulate their little compartments within the larger cells.

A Therefore, cells not only make up living things; they are living things. Cells are found in all plants, animals, and bacteria. Many of the basic structures found inside all types of cells, as well as the way those structures work, fundamentally are very similar, so the cell is said to be the fundamental unit of life.

B The key principle is that the smallest unit of life is the cell. ... But anything that makes up a cell necessarily has to not be alive. So all of the organelles in a cell like the nucleus, mitochondria, and endoplasmic reticulum are all non-living

C A non-living thing is not organized into cell(s); a living thing is. Although both non-living and living things are essentially made up of molecules of elements and compounds, a living thing would be made up of biomolecules organized into structures of a cell.

D All living things are made of cells; the cell itself is the smallest fundamental unit of structure and function in living organisms. (This requirement is why viruses are not considered living: they are not made of cells. ... Cells are classified as prokaryotic or eukaryotic.

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.
