How are plants pollinated?
Answer:
People can transfer pollen from one flower to another, but most plants are pollinated without any help from people. Usually plants rely on animals or the wind to pollinate them.

When are two populations likely to have very similar allele frequencies?
A. If the selective pressures are different
B. If there is a high mutation rate
C. If there is a large amount of genetic drift
D. If there is a large amount of gene flow
Answer:
c). If there was a large amount of genetic drift.
If the price of gene drift is excessive enough, then two populations will have equivalent allele frequencies and consequently can be taken into consideration as a single powerful population.
What causes allele frequencies to live equally?Allele frequencies continue to be constant over the years due to the following: there is no considerable price of a brand new mutation. individuals with all genotypes are similarly able to mate and pass on their genes; that is, there's no choice against any precise genotype.
What are two impacts of allele frequencies of a population?The natural choice, genetic drift, and gene go with the flow are the mechanisms that purpose modifications in allele frequencies through the years. while one or greater of those forces are appearing in a populace, the populace violates the Hardy-Weinberg assumptions, and evolution occurs.

The atmospheric temperature decreases when snow starts melting because the snow
melt
Answer:
The atmospheric temperature decreases when snow starts melting because the snow absorbs thermal energy from the atmosphere to melt.
Explanation:
The temperature of the air, the intensity of the sun, the speed of the wind, and the amount of humidity are the factors that influence the melting of the snow. The thermal energy in the atmosphere is absorbed by the snow because the temperature of snow is less than the temperature of the atmosphere. When the flow of temperature takes place, the energy also flows. The thermal energy helps the snow to melt because the snow requires warmth to melt.

A scientist studies the DNA in corresponding genes of a platypus, a
beaver, and a duck. The DNA from which two species are most likely to be most
similar? Explain your answer.
Answer:
platypus and a duck has similar DNA.
Explanation:
There are certain similarities which are present between duck and platypus such as structure of beak or mouth, webbed feet and laying eggs in order to continue its generation. These three characteristic make the platypus and duck similar to each other. There is also one major difference is present which is that the platypus is the only mammal which lay eggs and feed baby with their own milk. Its tail structure is also different from duck.
The DNA from platypus and beaver are most likely to be most similar because these species share a more recent ancestor.
Sequence homo-logy refers to the level of similarity between nucleotide (DNA) sequences due to shared ancestry in the evolutionary history of life.The species that share a more recent ancestor exhibit a higher level of sequence homo-logy than unrelated species.In this case, the linear order of nucleotides in DNA from platypus and beaver are most likely to be most similar because they are mammals, while ducks are birds.In conclusion, the DNA from platypus and beaver are most likely to be most similar because these species share a more recent ancestor.

if a disease killed all the seagulls what effect would this have on the food web?
Answer:
if the disease kills all the seaguells then it will affect the food chain negativleyy because the population of the species that would eat them (predator) will decrease dramatically and the fish ( what the seaguells eat ) there peopulation will increase dramatically because they are not being eaten .
Explanation:
hope this helps , sorry middle school was a long time ago for me : )
Answer and explanation: it would mean that there would be an increase of fish which is what seaguls eat but a decrease of, for example, leopard seals because if there aren't enough seagulls the leopard seals would die of starvation which would then again decrease another animal species because there aren't enough leopard seals. This would then repeat itself again and again.

Based on the information in the graph, explain what physical process causes the cell to change size.
Answer:
Osmosis
Explanation:
Osmosis is the process in which solvent molecules move from lower to higher concentration through a semipermeable membrane.
When a cell is placed in a hypertonic solution, the cell loses water and moves from higher concentration to lower concentration that is from inside the cell to the water solution and causes shrinking of cell.
Shrinking of cell means decrease in size of the cell along with the passing time and cell loses all its water.
Hence, the correct answer is osmosis.

please help Mark and Vikki live in two different areas of North America. The temperature in Mark’s town today is 30°F. The temperature in Vikki’s town is 82°F. In both towns, the relative humidity is 90%. Is the amount of water vapor in the air the same in Mark’s and Vikki’s towns? Explain your answer.
Answer:
I think that the amount of water vapor in the air will be different because in Mark's town, it is cold and water in the clouds might turn to ice and come down as snow. And in Vikki's town, it is very warm so the water vapor might come down as rain.

Answer: So they can live and grow.
Explanation: Plants have adaptations to help them survive (live and grow) in different areas. Adaptations are special features that allow a plant or animal to live in a particular place or habitat. These adaptations might make it very difficult for the plant to survive in a different place.
