How does ovolution lead to both biodiversity and commonalities among
life?

Answers

Answer:

Evolution leads to biodiversity by changing the genetic code of organisms. When evolution leads to biodiversoty its called natural selection. It slowly decreases the popluation of organisms that are less adapted to survive in the world, and increas the population of more strong and adaptable organisms.

For example if there is a pink bird and a white bird, the white bird's population will increase due to its adaptation of camoflauge, and the pink bird will die out because it will be spotted by predators easily. Therefore the species of the white bird will become more common

How many years might primary succession take with medium amounts of rainfall and temperature? Explain why ​ HELPP PLEASE HELP

Answers

Answer:

The primary succession process can take hundreds of years to happen, even in medium amounts of rain and temperature.

Explanation:

The primary succession occurs when a community of plants begins to sprout in areas that have never been occupied by any type of living being. The primary succession occurs, for example, with the sprouting of vegetables in rocky outcrops. These plant species are known as primary species and although they are able to survive, these environments offer few resources for the development of living things. Generally, it takes hundreds and even thousands of years for primary succession to occur, even in environments with average temperature and precipitation.

Primary succession takes more than 100 years to occupy with medium amounts of rainfall and temperature.

What do you mean by Succession?

Succession is the gradual and continuous replacement of one community by another community over a long period of time.

Primary succession is the succession that is starting for the very first time, where there is no life that existed before. It usually started from a bare area. Examples of primary succession include Igneous rock, Glaciers, etc.

It is associated with the occurrence of new sprouted life forms arising in a given area. This activity requires more than 100 years when there is a sufficient amount of rainfall and temperature is there.

Therefore, Primary succession takes more than 100 years to occupy with medium amounts of rainfall and temperature.

A small creek runs through a mature forest, keeping the soil around the creek damp all year. A variety of ferns and several flowering plants thrive in this shady, moist area. Along the higher ground above the creek, many species of flowering plants that need less water grow. If a farmer diverted the creek to water his fields, causing the creek to dry up, what would be the most likely long-term consequence for the ferns and angiosperms in the forest?

The ferns would outcompete the angiosperms in the forest since they can tolerate a wider range of moisture conditions than angiosperms.
The angiosperms and the ferns would not be affected since their thick, waxy cuticle coverings would protect them from drying out.
The angiosperms would outcompete the ferns since their sperm do not need moist conditions to get to their eggs as ferns do.
The ferns and angiosperms would begin to produce spores instead of seeds since the spores are better able to survive dry conditions.

A scientist studying the effects of radiation on DNA performs an experiment in which she exposes a sequence of nitrogen bases found in DNA to radiation. The DNA before and after the radiation is shown below.
Use the evidence to determine whether a mutation has occurred, and if so, interpret that mutation in the answer sheet provided

Before Exposure: ATCGTCA; After Exposure: ATTCGTCA

A. No mutation has occurred to the DNA sequence.

B. A nitrogen base has been deleted from the DNA molecule.

C. A nitrogen base has replaced another nitrogen base in the DNA molecule.

D. A nitrogen base has been added to the DNA molecule.

Answers

Answer:

D. A nitrogen base has been added to the DNA molecule.  

Explanation:

You can see that the sequence for the nitrogen bases are in the exact same order after the exposure, this rules out A.  You can count how many bases there are, 7 before and 8 after so it cannot be B. Lastly, given that they are in the same order as were before and that a base has been added, you can see that no bases were replaced (so not C) and that D is your answer.
