The science club at Tracy's school is researching how temperature affects fish reproduction. They conducted a study to find out if raising the water temperature would decrease the number of bass eggs that hatched.
They gathered bass eggs from a local lake. Half of the aquariums were kept at room temerpature, and the other half were placed in a sunny window.
What is the independent (test) variable from this experiment?
The size of the lake.
The number of bass eggs that hatch.
The temperature of the water.
The number of aquariums.
Answer:
The temperature of the water.
Explanation:
The independent variable is the thing you are changing in order to observe an outcome. The dependent variable is the outcome (the number of bass eggs that hatch).
Wetlands are
areas where water covers the soil. Swamps, marshes, and other wetland
areas help to control flooding because they naturally hold water. Wetland regeneration
is a recent trend in conservation.
In some areas, land previously used for farming iS
being converted into wetlands.
Research wetlands, the types of organisms that live there, and examples of wetland
restoration and regeneration. Then answer these questions:
What factors do scientists need to
consider before turning farmland into wetlands?
How could wetland restoration affect humans who live in the area? How might it
affect native wildlife? (Consider both positive and negative consequences.)
If you were planning a wetland regeneration project,
success?
how would you monitor its
Answer:
I think its great that farmland is being converted to wetlands, wetlands reduce the amount of co2 in the air and prevent floods. Some factors scientist need to consider is how wetlands can affect civillians as wetlands can lure dangerous animals such as alligators. Converting farmland to wetland would be successful due to the fact that wetlands can provide shelter to animals and can reduce co2 in the air, I recommend researching the topic further and to take my word with a grain of salt.
Explanation:
The bottom explanation might be a little worse due to the fact that I want it to be somewhat different from the top one, both explanations work fine in my opinion but the top one is better.
Another great explanation is: I believe wetlands are amazing for the enviroment as they prevent floods and give shelter to animals, wetlands can't really affect civillians negatively other then dangerous animals. I would most likely moniter its success by seeing how much water the wetland can hold, if it can hold an average amount then I would say the restoration was successful.
Plants are considered to be ___________ because they are the only living organisms that make their own food.
Answer:
heterotrophs
Explanation:
plants can prepare their own food due to a process called photosynthesis.
animals depend on other animals or plants to make their food so they are called autotrophs

• also known as tropical grasslands
• few trees due to little rainfall
1)
(Savannas)
(Both Types of
Grasslands)
(Temperate
Grasslands)
Answer:
S - Savannas are typically found in tropical or subtropical regions.
S - Savannas tend to have more trees and shrubs.
S - Savanna's climate is drier than that of a grassland.
G - Grasslands are found in temperature regions.
G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.
G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.
B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.
B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.
B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.

How would antelopes be affected if they cannot find enough plant matter to eat?
PLEASE IN 10 MINUTES!!
Answer:
Explanation:
Most antelopes are herbivores which means they eat only plants. If they cannot find enough plant matter to eat, slowly, the population in a herd of antelopes would go down from the lack of nutrients and energy they need from the food they eat(vegetation).

A student wants to find out if the amount of bleach has an effect on stain removal.
He plans to use two white shirts, stain each of them with mustard, and then wash each of them using bleach. He can change the size of the stain on the shirt and the amount of bleach he adds to the water.
Which test should the student set up?
Answer:
The second option.
Explanation:
We're trying to test the amount of bleach that has an effect on the stain so that is the altered variable.
The 2nd option uses different amounts of bleach to clean the same amount of stain.
If you choose the other options, people can argue that the bigger stain would be harder to clean with one cup of bleach, whereas the small stain gets two cups or the other way around.
It's not an effective way to see if the amount of bleach has an effect on stain removal.

By adding tape to his BAAD, Cramwood increased its mass and increased
its inertia. The bigger BAAD requires more force to stop and ends up smacking Cramwood in the head when he applies the brakes.
What is inertia?Inertia is the tendency of an object to resist a change in its motion. Specifically, it is the property of matter that causes an object to maintain its state of rest or uniform motion in a straight line unless acted upon by an external force.
In other words, an object at rest will remain at rest, and an object in motion will continue to move at a constant speed and in a straight line, unless acted upon by an external force.
The amount of inertia an object has depends on its mass, with more massive objects having more inertia than less massive objects.

25 PTS MIGHT GIVE BRAINLIEST Imagine that you are a grain of pollen on a flower that cross-pollinates
the flower of another plant of the same species. Write a journal
entry in complete sentences describing your journey. Correctly
include each of these terms in your entry: pollinator,
pollen, pistil, stamen, anther, stigma, ovary, and eggs
Answer:Pollination is the transfer of pollen grains from an anthers to a receptive stigma. In most species of flowering plants, external agents bring about pollination. Also, flowers have evolved special structures and mechanisms to ensure successful pollination.
There are two types of pollination
--> Self pollination: This takes place when mature pollen grains from the anther of a flower fall on the stigma of the same flower or that of another flower on the same plant. This type of pollination brings the male gametes and egg cells of the same plant together. The resultant offspring show very little genetic variation.
--> Cross pollination: This occurs when mature pollen grains of a flower are transferred to the stigma of a flower of another plant of the same or closely related species. This brings the male gametes and egg cells of two different parent plants together. Therefore, there is greater genetic variation among the offspring.
Explanation: i hope this can give you a little push!
Answer:
As a grain of pollen on a flower, I am responsible for cross-pollinating the flower of another plant of the same species. I began my journey on the stamen of one flower, where I picked up the pollen from another. I was carried to the pistil of the next flower and deposited the pollen on the stigma. I then traveled down the style to the ovary, where I fertilized the eggs, commencing the production of the next generation of this flower.

What is happening because of increased human population?
ease of pressure on natural resources
increased pressure on natural resources
An increased pressure on natural resources happens due to increased human population.
As the human population increases, there is often an increased demand for natural resources such as food, water, and energy. This can lead to the overuse and depletion of these resources, as well as negative impacts on the environment and ecosystems.
With the increasing population, there is also an increased pressure on land and housing, leading to urbanization, deforestation, and loss of biodiversity. Moreover, the increased population also leads to increased pollution and waste generation, which can harm the environment and human health.
In addition, the increased human population can also lead to increased competition for jobs and other economic resources and can strain social and political systems.
Overall, the increased human population can lead to a variety of negative impacts on the environment and natural resources, as well as on human societies and economies.
