Which are examples of how animals are used to disperse seeds? (Select all that apply.)
seeds being passed through an animal’s digestive system
seeds being carried on people's clothes
seeds being carried in animal fur
seeds being inhaled when an animal breathes
Answer: All of those apply except for the seeds being inhaled when an animal breathes.
Hi :)
The answer is below.
Seeds passed through and animals digestive systemSeeds being carried in animal furSeeds being inhaled when an animal breathes-How does the fur of animals give seeds?When animals eat the seeds,other seeds have hooks on the fur or skin of animals.The seeds fall off when they walk around.
-How do they get seeds from the digestive system?When animals use the bathroom all over the place, the seeds are on their waste, the seeds go every where when the use the bathroom.
-How do animals inhale these seeds?When animals breathe, they inhale the seeds on the ground. Seeds that have fallen from trees, plants, ect. (It tells you this right in the answer choice)
-Why isnt seeds being carried on people's clothes correct?
Seeds have hooks, yes, but it doesnt mean they will stick to humans. Humans are not normally in the wild with seeds and animals. So this is not very likely to happen.
Hope this helps!This has been,
~NatLikesAnime~#LearningWithBrainlyWhat is the difference between compost and humus?
Humus occurs in nature unaided by humans.
Compost occurs in nature unaided by humans.
Humus does not break down the elements as well as compost does.
Compost does not break down the elements as well as humus does.
Answer:
A. Humus occurs in nature unaided by humans
Explanation:
got it correct in my quiz hope this helps and have a nice day :)
The difference between compost and humus is that humus occurs in nature unaided by humans, which is the first option, as humus is a natural organic substance that forms over a long period of time as organic matter, and compost is created by humans.
What are compost and humus?Humus is a naturally occurring organic material that is formed through the natural decomposition of plant and animal matter over a long period of time. It is a stable form of organic matter that is resistant to further decomposition, and it can persist in soil for centuries or even millennia. Compost is a valuable soil amendment that can be used to improve soil health and fertility. Unlike humus, which is a stable form of organic matter, compost is a more dynamic material that continues to break down over time.
Hence, the difference between compost and humus is that humus occurs in nature unaided by humans, which is the first option.

In the spring of each year, the second largest dead zone in the United States forms in the Gulf of Mexico. During the spring, farmers fertilize their land as they prepare for crop season. As a result, nutrients from the fertilizers, such as nitrogen and phosphorus, drain into the Mississippi River and eventually the Gulf of Mexico. According to the National Oceanic and Atmospheric Administration, “Excess nutrients that run off land or are piped as wastewater into rivers and coasts can stimulate an overgrowth of algae, which then sinks and decomposes in the water” (NOAA, 2018). The decomposition process consumes and depletes oxygen levels in the Gulf of Mexico, which causes hypoxic areas or dead zones.
A group of scientists measured several water quality parameters to better understand how dead zones in the Gulf of Mexico impact brown shrimp populations over time. The scientists are most interested in the dissolved oxygen levels because the levels are critical for the survival of brown shrimp populations. Brown shrimp populations thrive when dissolved oxygen levels in the Gulf of Mexico are greater than 2 mg/L. However, the populations cannot thrive when dissolved oxygen levels are at or below 2/mg/L.

How many carnivores are there compared to herbivores?
Answer: 63%
Of all the present-day animals Wiens and colleagues surveyed, 63% were carnivores, 32% were herbivores, and 3% were omnivores. (The rest were ambiguous.) The smaller proportion of herbivores and omnivores may seem surprising, Wiens says, because plants are such a plentiful resource.

Question 16 options:
Sunspot activity
Change in Earth's position with respect to the sun
large asteroid impact
Significant plate movements
According to this Significant plate movements affects short-term climate, but not long-term climate.
What are the short term effects of climate change?Higher temperatures will heat the ocean. This will result in more heat energy, which will improve the potential for tropical storms to develop.
As warming also shows more evaporation, heavy rains and snowfalls become more regular, making torrents and cyclones more intense.
Thus, Significant plate movements affect short-term climate, but not long-term climate.

Use the information and pictures to answer the following question.
In August 2010, the Asian Clam was discovered in Lake George. It is not native to that lake. A single Asian Clam can reproduce and release hundreds of offspring in a day. Fish and crayfish eat the clams but cannot keep pace with the rate at which the clams reproduce. The Asian Clam eats the same food as native clams.
A scientist set up two model lakes in large tanks with the same animal species as Lake George in order to test how the Asian Clam might be impacting the ecosystem. The scientists added Asian Clams to one tank but not the other tank.
image
Which statement BEST predicts what would likely happen in the experimental tank?
A.
The impact would be negative because it would reduce the amount of food available for the fish and crayfish populations.
B.
The impact would be positive because it would reduce competition with native clams and increase the stability of the ecosystem.
C.
The impact would be negative because it would increase competition with native clams and reduce the stability of the ecosystem.
D.
The impact would be positive because it would provide the fish and crayfish populations with food.
Answer:
C.The impact would be negative because it would increase competition with native clams and reduce the stability of the ecosystem.
Explanation:
Since, It states that:
Tank 1: Tank 2:
Fish Fish
crayfish crayfish
Asian clam
-------------------------------------------------------------------------------------------------------------
Thus, since they both eat Asian clam which means competition as well as it would be negative. Therefore, that left us with [C] .
Hence, Answer = [C]

Explanation:
A new neighborhood is built and completely destroys most of a forest. Soon, deer are walking down the sidewalks and eating plants and flowers from yards.
What is the most likely reason why this is happening?
The forest has plenty of food for them, but the deer see easier, newer food sources in the humans’ yards, so the deer are in the neighborhood because they prefer the food there.
The deer have been living close to humans and have become used to seeing them and are being curious since deer like humans.
The deer have been forced into a small area and lack enough food, so they are wandering out of their small forest home searching for food.
The light from the neighborhood has confused the deer, and so they are wandering into the streets because they are disoriented.
Answer:
I think its the 3rd answer
Explanation:
The first answer could be close but if the forest was mostly destroyed, then it would not have plenty of food for them. They also might not prefer the food there. The second option isn't correct because the deer wouldn't take their chances being around creatures (humans) that they have never seen before or didn't see that much. Also, the sound of the construction would scare them off. The fourth option isn't correct because while yes, the lights may disorient the deer, it probably wouldn't want to make the deer wander into the neighborhood. When you see a deer looking in headlights, they don't walk towards your car, they just stand there. This is why I think the 3rd answer is correct.

How do the roots and stem take part in the transport of water in a plant?
please make a good explanation and make long answer pls! thanks :D
Answer:
The roots take part in the transport of water in a plant by absorbing water from the ground. The stem moves the water to the rest of the plant.
Explanation:
When a plant is in wet soil, the roots absorb the water from the ground and carry it to the stem. Then, the steam acts as a passageway and the water goes up the steam, and into other areas of the plant, sucks as leave, and (if the plant has them) flowers.
