Answer 2: Here are 10 ways to reuse potato chip bags.

At picnics or parties, use for most any food that doesn't need a lid container.

Use in car trunk to store either clean or dirty rags.

Use to wrap up breakables for transporting.

Put babies dirty diapers, especially throwaways when you are going to use a public trash can.

Use to store or carry baseballs. You can get about 12 hardballs in a large bag or 6 softballs.

Use the bag to collect berries, pine cones, or any other little treasures you find on your nature walks.

Use to carry your caught fish home.

Use to bury your desceased pet parakeet, fish, gerbils or hamster. Just wrap them up in a bag and bury.

Use as a trash bag for your vehicle.

A large empty potato chip bag will make 2 one time picnic table place mats.

plz help asap! The activity of many cellular enzymes is regulated by activators and inhibitors. Enzyme activity is also regulated in eukaryotic cells by which of the following mechanisms?

Compartmentalization and restricting enzymes to specific organelles or membranes
Secreting enzymes out of the cell
Limiting the availability of substrates
Changing the primary structure of enzymes

Answers

Answer:

compartmentalization and restricting enzymes to specific organelles or membranes

Cellular steroid gradients are produced by the compartmentalization of enzymes into various organelles of a cell, and this might impact how well the various steroid products are balanced. Thus, option A is correct.

What is Compartmentalization?

In biology, the biomembrane, or biological membrane, effectively compartmentalizes enzymes by allowing them to perform only certain functions within a limited area.

The enzymes may be located on the membrane surface or inside the defined compartments.

A percentage of the enzymes would likely not work or their ability to catalyze reactions would likely be insufficient if there was just one cellular compartment.

This is because enzymes catalyzing distinct reactions frequently have variable temperature and pH optimums.

Therefore, Compartmentalization and restricting enzymes to specific organelles or membranes.

A sugar farm near the coast of Florida applies a nitrogen based fertilizer to their soil three times a year. When rain falls on these fields after it has been fertilized some of the fertilizer runs off into the ocean causing the nitrogen levels in the water to increase. The increase levels of nitrogen can lead to many ecological effects beginning with the rapid growth of algae. This process is known as eutrophication.

How can eutrophication affect other organisms in the water?

Group of answer choices

The algae provide food for fishes and other organisms, leading to decreased algae populations.

The oxygen in the water is used up as algae is decomposed, reducing the amount available to other organisms.

The water becomes better able to support aerobic organisms.

The extra nitrogen provides additional food for the other organisms, increasing their population.

Answers

Answer:

The algae provide food for fishes and other organisms, leading to decreased algae populations

Explanation:

Excessive nutrients lead to algal blooms and low-oxygen (hypoxic) waters that can kill fish and seagrass and reduce essential fish habitats. ... Eutrophication sets off a chain reaction in the ecosystem, starting with an overabundance of algae and plants.

Peter, who lived 200 years ago, had a house with no rats in it. One day, his wife
heard some scurrying around on his straw roof. He went up and guess what he
found? A rat's nest. Peter was really smart--where did he think the new rats came
from? Well 200 years ago, people believed that part of the straw roof somehow
turned into rats. Why would Peter, even though he was very intelligent, accept this
idea?
We're all really smart, but its not like we're the smartest people in the world. We all know that it takes a momma rat and daddy rat to make some baby rats.
This is because we understand something called the cell theory, because the cell theory is just part of our culture now. It's something a lot of our behaviors and
other ideas are based.
1. All living things are made of cells
2. Cells come from other cells
3. Cells are the smallest unit of life

1. Using two parts of the cell theory, explain to Peter why these two parts show
that the straw roof did not turn into the rats.
2. What do we mean when we say 'The cell is the smallest unit of life? Explain as if
you were talking to Peter, who has no idea about cells.

Explanation:

All living things are made of cells  and Cells come from other cells are the two parts of the cell theory.

These two statements are used to show to peter about the presence of rats in the straw roof. The straw roof did not turn into the rats because straw is a non-living whereas rats are living. Rats increases its population when the male rate mate with the female rate produces baby rats.All living organisms has the ability of reproduction through sexual and asexual.The cell is the smallest unit of life' from this statement we mean that the body of all living organisms are made up of cells just like a building which is made up of bricks so we can say that this example is enough for the Peter to understand the statement about cells.

The difference between biotic and abiotic factors is that abiotic means non-living and biotic means living, that is the first statement, as biotic factors refer to living organisms in an ecosystem like plants and abiotic factors include soil.

What is the difference between biotic and abiotic factors?

Biotic factors refer to the living organisms in an ecosystem, such as plants, animals, fungi, and microorganisms, and these organisms interact with each other in various ways, including through predation, competition, and mutualism, while abiotic factors refer to the non-living components of the environment, such as air, water, soil, sunlight, and temperature, which can have a significant impact on the distribution and behavior of biotic organisms within an ecosystem.

Hence, the difference between biotic and abiotic factors is that abiotic means non-living and biotic means living, which is the first statement.

Transcription is the process that must happen in order to make

Answers

Answer:

a protein

Explanation:

Transcription is one of the three main, necessary events needed for proteins to form in a cell. This happens when DNA is transcribed to mRNA. Thymine (T) is subbed in by Uracil (U), so when transcribing, A's turn into U's, not T's.

Transcription is the first step of gene expression. During this process, the DNA sequence of a gene is copied into RNA. Before transcription can take place, the DNA double helix must unwind near the gene that is getting transcribed. The region of opened-up DNA is called a transcription bubble.
