Matter changes state when energy is added or taken away. When matter is heated enough, the molecules move faster and with greater energy. ... If enough heat is added, a solid can become liquid and a liquid can become gas.
When humans come to a previously pristine environment, they inadvertently bring organisms with them that can be harmful to the local flora and fauna. Such organisms are known as _____.
Answer:
INVASIVE species
Explanation:
In biology, an organism is said to be INVASIVE if the organism is foreign to a particular region or habitat and possess the unpleasant ability to proliferate or grow rapidly to the point of competing with local species of organisms.
According to this question, humans are said to introduce organisms that have the ability to harm the local flora and fauna. Hence, these organisms are INVASIVE SPECIES because they are foreign to that place and cause damage in their new environment.

A class is debating the advantages and disadvantages of different types of reproduction. One student argues that organisms that reproduce asexually, like bacteria, have no advantage over organisms that reproduce sexually.
Which of the following choices below represents an argument for the advantages of asexual reproduction?
A. Organisms that reproduce asexually are likely to find a mate at a faster rate than sexually reproducing organisms, which allows them to reproduce faster.
B. Organisms that reproduce asexually are more diverse and are more likely to pass on key genes for survival to future generations, which aids in maintaining beneficial genes for survival in the gene pool
C. Organisms that reproduce asexually gain variation through processes like crossing over, which allows survival in instances of ecological change
D. Organisms that reproduce asexually create a large amount of offspring in a short period of time in order to maintain their population
Answer:
D
Explanation:

Emma lives in Wisconsin and wants to plant geraniums in her yard. The average daily temperature in her area is 21°C (70°F) and the nighttime temperatures are averaging 18°C (65°F). The area where she would plant the geraniums gets full sun all day. Would you suggest she plant her geraniums? Why or why not?
Answer:
Please mark brainliest
Explanation:
Yes, because geraniums live on land that has a temperature of 65 degrees F and 70 degrees F.

Name the enzyme that breaks the hydrogen bonds holding the
two DNA strands together during DNA replication?
DNA helicase is the enzyme that breaks the hydrogen bonds which holds the two DNA strands together during DNA replication.
What is DNA helicase?During replication of DNA , the enzyme DNA helicase separates the two strands of DNA and causes the breakdown of hydrogen bonds between the two DNA strands which leads to separating of the DNA double helix into two individual strands which make easier to copy it.
In conclusion, DNA helicase is the enzyme that breaks the hydrogen bonds.

When your cells use fat for energy, the fatty acids are broken up into molecules of acetyl CoA. Predict how many ATP can be made from one molecule of acetyl CoA if oxygen is present. Show your work.
Answer: Suppose that each fatty acid in a certain fat can make 9 molecules of acetyl CoA. Predict how many ATP can be made from the fatty acids in this fat. This would make 27 acetyl CoA, and therefore would make 27 ATP

r If a mouse population changes color from white to black over many generations, which question should be asked to determine whether the population changes are a result of natural selection or artificial selection?
A.
What do humans need to keep mice healthy as pets?
B.
Was there a change in the genetic traits of the mice?
C.
Were the genes of the mice inherited from their parents?
D.
Was there a change in the environment where the mice live?
Answer:
D if there is a change in environment that would favor black fur you could assume that natural selection caused the fur to change
Explanation:
The question which should be asked to determine whether the population changes are a result of natural selection or artificial selection is that was there a change in the environment where the mice live? Thus, the correct option is D.
Natural selection is the process through which the populations of different living organisms adapt and change with respect to their surrounding environment. Individuals in a population are naturally variable, it means that they are all different in some way or the other. This variation in the population means that some individuals have traits which are better suited to the surrounding environment than others.
If a mouse population changes its color from white to black over many generations, then the question which should be asked is "Was there a change in the environment where the mice live?"
Therefore, the correct option is D.

Which of the following statements describes a process that occurs during photosynthesis but not during cellular respiration?
ATP is produced that stores energy.
O
Chemical energy is converted to light energy.
Reactions occur in the mitochondria of the cell.
Light energy is converted to chemical energy.
Answer:
D (see below for explanation)
Explanation:
Using the process of elimination, we can go down the answer choices:
A) ATP is produced that stores energy.
In photosynthesis, light energy, water, and carbon dioxide is taken in and converted to oxygen and glucose. Cellular respiration, however, uses glucose and oxygen and converts it to water, carbon dioxide, and ATP.
As you can see, there is no mention of ATP in photosynthesis. ATP is not created in photosynthesis—photosynthesis' main purpose is to make food for the organism.
So A is not the answer.
B) Chemical energy is converted to light energy.
In photosynthesis, the light energy taken in is converted to chemical energy so it can be used. Cellular respiration requires only oxygen and glucose, so light energy doesn't relate to cellular respiration directly.
However, if you read the answer carefully, it says that chemical energy is converted to light energy. The main purpose is to use the light energy, which cannot be used in its light form, so it has be converted into chemical energy.
So B is not the answer.
C) Reactions occur in the mitochondria of the cell.
Photosynthesis occurs in the chloroplasts of an organisms. Heterotrophs do not have chloroplasts, so they cannot make their own food. However, mitochondria are in all eukaryotic cells, as cellular respiration occurs in all eukaryotic cells as well.
Cellular respiration happens in the mitochondria of a cell. Photosynthesis does not.
So C is not the answer.
D) Light energy is converted to chemical energy.
If you go back to my explanation for B, you can see that photosynthesis uses light energy, but to do so, it has to convert it to light energy first. It cannot use light energy itself.
So D is the right answer.

00
buy biodegradable plastics
С
use canvas bags when shopping
D
use paper bags instead of plastic bags
Answer:I feel like some of the answers for me would be A and B but if you only had to choose one I would choose A
Explanation: When you buy recycled you are helping the local economy and the environment. You already know that recycling keeps useful materials from going to waste in landfills or incinerators. But did you know that buying recycled-content products ensures that markets for those recovered materials are strong
Edit: Just figured out it's not B here's why:
Plastics marketed as "biodegradable" will contribute to plastic pollution if they are lost or littered. They do not break down as quickly and completely in the environment as the term might imply and thus can harm wildlife and ecosystems. Sorry if it's long
At the time when the consumers do to make sure that more materials are recycled so here option A is considered i.e. buy products made from recycled materials.
Recycled materials:At the time when we purchase the recycled so you helped the economy as well as the environment. Also, recycling plays a vital role for minimizing the wastage and make the proper utilization of the product.
