Answer:
All prokaryotes have 70S (where S=Svedberg units) ribosomes while eukaryotes contain larger 80S ribosomes in their cytosol. The 70S ribosome is made up of a 50S and 30S subunits. Ribosomes play a key role in the catalysis of two important and crucial biological processes.
If two populations of people share the same DNA "spelling difference" (i.E., mutation), what does this mean about these two populations?
Answer:
It could mean that those two populations could be common ancestors because the spelling differences are the same
Explanation:
The similar spelling variations between the two populations could imply that they share common ancestry.
What is DNA?Deoxyribonucleic acid, or DNA, is the name given to the genetic material carried by humans and nearly all other species. An individual's DNA is present in nearly all of their cells.
Nucleotides are the molecular building components that make up DNA. A phosphate group, a sugar group, and one of four different nitrogen bases make up these building components. Nucleotides are joined into chains and the locations of the phosphate and sugar groups are switched to form DNA strands.
Every cell in the body has DNA in its nucleus. Groups of these firmly bound fragments make form chromosomes. The majority of people possess 46 pairs of chromosomes, or 23 pairs per pair.
Thus, The similar spelling variations between the two populations.

In the United States, there has been an increase in the number of people infected by mosquito spread diseas that were previously found only in countries south of the United States. Scientists want to investigate the cause of the increase in mosquito spread diseases. Scientists have predicted that the mosquitos carrying disease have moved further north as global temperatures have increased. Which questions would help investigate how the new mosquitoes are affecting the ecosystems of the United States ? Select all that apply. AHow much money has been spent to fight the diseases caused by these mosquitoes across the globe? B. How have the food webs in the United States changed as a result of the new mosquitoes? the natural predators to the mosquitoes also migrated north? What types of organisms are preying on the mosquitoes in their new habitats? E Are places in the United States using more pesticides to kill the new mosquitoes? If so, how are these pesticides impacting others in the ecosystems
Answer:
What types of organisms are preying on the mosquitoes in their new habitats?
Explanation:
I think it is all the answers except for What types of organisms are preying on the mosquitoes in their new habitats? this is because when a new species comes to an area it does not have anything to prey on it

Question 23 (6 points)
Sea Urchins are aquatic mammals that dive down to catch and eat sea urchins. Sea
urchins hunt the sea floor to catch and eat starfish. Starfish feed off of kelp forests
under the sea.
When sea otters overpopulate they clean out the sea urchins very quickly. This
allows the starfish to overpopulate and eat too much of the kelp forests.
Answer the following questions for 2 points each:
1. Name the TWO organisms that act as Carnivores in the ecosystem described
above.
2. Identify the ecological roles of the other TWO organisms.
3. Identify which of the four organisms above would be considered a keystone
species. Explain why.
Answer: 1. Sea urchins and sea otters
2. They are prey for carnivores.
3. Sea otters, star fish
Explanation:
Sea urchins and sea otters are carnivores as they eat on the flesh of starfish and sea urchins respectively.
Starfish feed on the kelp forests which are the producers in the food chain and the starfish is the primary consumer and prey for sea urchins. So, starfish and kelp forests are the prey in the marine ecosystem.
Keystone species is the one which controls the population of other inferior species in an ecosystem. Here, sea otters consume sea urchins so the population of sea urchins remained in control Starfish controls the population of kelp forest.

a) evolve.
b) migrate.
c) survive.
d) mutate.
Answer:
b migrate
Explanation:
sorry if im wrong
The more genetic variation a population has, the more likely it is that some individuals will migrate.
what is population ?A discrete accumulation identifiable characteristics such as people, animals with the objective of analysis and data collection is called a population.
A population consists of a same group of species who reside in a particular geographical place with their reproductive capacity to interbreed.
In a population Not all individuals are able to survive and reproduce due to genetic variations in them, a local population is restricted to a smaller area or can occupy a larger area, making up for the entire species.
when individuals in local populations spread between other local populations called as metapopulation.

A student conducted an experiment with two rose plants to determine if a liquid formula for fertilizer produced greater growth than a dry formula. After testing each fertilizer on two different plants for one month, his data led to the conclusion that the liquid formula was a better promoter of plant growth. When he described his conclusion to his teacher, she told him he needed to conduct additional trials. The teacher most likely asked for additional trials because O she did not believe the new formula helped plants grow better than the old formula. O it was necessary to see data from more plants before the conclusion could be accepted. O it was necessary to have tested the fertilizer on different kinds of plants. O she thought he should test additional fertilizer formulas on the same two plants.

Which of these is an example of selective breeding?
A.
A scientist places bacteria in a Petri dish treated with antibiotics and observes what happens to the population over time.
B.
A farmer plants tomato seeds that have been genetically modified to be pest resistant in his garden.
C.
A farmer only allows trees that produce tart apples to reproduce until he has a population that only produces tart apples.
D.
A scientist uses the genetic material from a unicellular organism to create an exact copy of that organism.
Answer:
the answer is C
Explanation:
Seletive breeding means only nuture one specific kind of species. In answer C, the farmer only allows trees produce tart apples to reproduce, so the answer is C.

This oceanic zone contains some of the
deepest parts of the ocean.
A. Kelp Forest
B. Abyssal Zone
C. Coral Reefs
The abyssal zone, which lies between 4,000 and 6,000 meters (13,000 and 20,000 feet) below the surface, is the deepest region of the ocean. So, option B is the answer.
The region of the ocean that lies beyond the continental shelf is commonly referred to as the oceanic zone. The sunshine zone, twilight zone, midnight zone, and abyssal zone are the four vertical zones that make up the open ocean.
Abyssal zone is characterized by high pressure, low temperatures, and very little light.
Kelp forest is found in shallower areas, often between 20 and 100 meters deep and Coral reefs are located in tropical, shallow waters.
Therefore, option B is correct.
