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.

How does soil composition affect the number and types of organisms an environment can support?
(Biome majors)
Answer:
The number of organisms an ecosystem can support depends on the resources available and abiotic factors, such as quantity of light and water, range of temperatures, and soil composition. Given adequate biotic and abiotic resources and no disease or predators, populations (including humans) increase at rapid rates.
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.

Which statement applies to transverse waves?
The waves have a trough.
Particles move great distances.
The waves have alternating compressions and expansions.
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.

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.

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.

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.

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?
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.
