Answer:
- There are three main steps to DNA replication: initiation, elongation, and termination.
- In order to fit within a cell's nucleus, DNA is packed into tightly coiled structures called chromatin, which loosens prior to replication, allowing the cell replication machinery to access the DNA strands.

Transcription is the process that must happen in order to make
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.

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.

Which of the following is not a stage in hurricane formation?
A)
Thunderstorms in a low-pressure area combined with the Earth’s rotation cause the storm’s initial rotation.
B)
Pollution in the atmosphere raises the temperature of the air, creating a depression.
C)
Warm, moist air rises from the sea and increases the storm’s energy.
D)
As water from the sea turns into water vapor, latent heat enters the storm, causing the storm’s energy to increase.
E)
As condensation (rain) occurs, latent heat is released, which warms the air and makes it lighter, causing the hurricane to increase in strength and intensity.
Answer:
B

The energy is transferred parallel to the direction of the wave motion.
Answer:
A) The waves have trough
Explanation:
100% sure
The statement 'the waves have a trough' applies to transverse waves.
What are transverse waves?Transverse waves are a type of wave in which their fluctuations need to be perpendicular to the wave.
Conversely, longitudinal waves are waves in which their oscillations have the same direction of the wave.A wave can be defined as any type of disturbance capable of carrying energy but that does not involve motion.In conclusion, the statement 'the waves have a trough' applies to transverse waves.

A population of sea urchins in a kelp forest ecosystem is being over-fished. A team of students believe that a decline in the number of sea urchins will affect the organisms in the kelp forest ecosystem. The kelp forest food web below shows the relationships among the organisms in the kelp forest ecosystem.
Answer:
Explanation:
This response shows some understanding of the question. The ecological relationships among the otter, crab, and urchin are addressed in a very general manner (kelp crabs and sea urchins feed off of kelp, only to be eaten by the sea otter). In a further explanation, the student overstates the effect of a decrease in the populations of the organisms. (The sea urchin and crab won't get the food from the kelp and die off. The otter will starve and die off too.) The supporting details are minimally effective.
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.
Answer:
1 is always rifht
Explanation:
i think so
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.Learn more: https://brainly.com/question/21867053

How does the theory of natural explanation explain the medical phenomenon of antibiotic resistance?
Answer:
Antibiotic resistance evolves naturally via natural selection through random mutation, but it could also be engineered by applying an evolutionary stress on a population. Once such a gene is generated, bacteria can then transfer the genetic information in a horizontal fashion (between individuals) by plasmid exchange.

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.
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.

Read the paragraph from the section "Pea Plants And The Punnett Square."
A pea plant could have one copy of the height gene that coded for "tall" and one copy of the height gene that coded for
"short." The tall allele is "dominant," and this means that it can mask the other allele. The short allele is called
"recessive." The allele combination of tall-short would result in a tall plant since the tall allele is dominant.
Which option is the BEST definition of the word "mask" as used in the paragraph above?

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
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.
