SOMEONE PLEASE HELP Which of the following examples is MOST likely to result in the formation of a new species? Select one:
A
A farmer applies a new fertilizer to her crops in order to encourage a much greater yield of corn.
B
An invasive species is introduced into the sea when an oil tanker releases the water it uses to float near a coral reef.
C
Many trees are knocked down when a new road is paved through a forest where many animal species live.
D
A fish population is divided when a long drought causes a lake to separate into two smaller bodies of water,
Answer: D
Explanation: The important thing to notice in this question is that it's asking for the FORMATION of a NEW species. That detail automatically removes B as the answer, because, while an invasive species could lead to a new species, it isn't likely, and there's the fact that B is talking about the INTRODUCTION of a species that already exists.
A could be correct, but fertilizer isn't likely to lead to a new species, as well as C, which would lead to a LOSS in species and biodiversity.
D is correct because it is an example of Allopatric Speciation, which is when one species converges into 2 species because of a physical barrier.
I hope this helps. Have a great week!

oxygen do they help replace?
Answer:
17%. They create 21% of the oxygen
Explanation:
Just used the search engine
The Russian taiga money is owed for fifty-seven percentage of the world's conifer wooded area and 23 percent of all of the world's woodlands.
The Siberian taiga is greater than Amazonia. Boreal forests make a contribution of twenty-one percent to the earth's atmosphere. Taiga Biome, wildfires are very common. They are important to put off vintage and ill trees. The common annual rainfall withinside the boreal wooded area biome is about 33 inches. The dominant plant withinside the taiga is the coniferous evergreen tree.What is a biome?
A biome is a place categorized consistent with the species that stay in that location. Temperature range, soil type, and the quantity of mild and water are precise to a selected area and shape the niches for particular species permitting scientists to outline the biome.
Thus it is clear that they have 21%of oxygen.

Describe one of the following weed control methods: chemical, biological, cultural, mechanical.
Answer:
Chemical method for weed control is an effective method.
Explanation:
Chemical method for weed control is an effective method for controlling of weeds in the field. In this method, chemicals are used to control the growth of weeds in the field. The weedicide chemicals only effects the weeds in the field because they are specific to certain plants. 2,4- D, Butachlor, Anilophos, Pretilachlor and Pendimethalin are the examples of weedicides. This method is very effective in controlling weeds which leads to increase in the productivity of crops.

Answer:
D. a quadrilateral with a short line on each side
Explanation:
This question is describing a SQUARE, which is a quadrilateral with four sides equal. A square has four angles as well, which are of equal sizes as well i.e. 90% each.
A quadrilateral with one small square in each of the four corners showing that each angle is a right angle (90°). In a square, same line are on each side showing that any side with the short line has the same length, hence, all sides have an equal length.

Your molecular clock model resembles another branching chart, the phylogenetic chart, which you've
used in this unit. Review the sample phylogenetic chart. What types of data are used to build a
phylogenetic chart? How do phylogenetic charts differ from molecular models, such as the molecular
clock model?
Answer: I do not know if this is correct, but this is what I answered.
Explanation:
Answer:
There are many types of data that a phylogenetic chart can use such as morphological data, such as structural features, types of organs, and specific skeletal arrangements; genetic data, such as mitochondrial DNA sequences, ribosomal RNA genes, and any genes of interest. Phylogenetic charts differ from molecular modes in many different ways such as the following. The phylogenetic charts considers various data types such as morphological data,molecule data, and behavorial data. On the other side, the molecular only considers one kind of data, that is, the genetic founded data.

Many countries in Europe and Africa are reluctant to import Genetically Modified Organisms (GMO) produced foods from the United States because Question 33 options: they could severely alter local agricultural economies. they could possibly crossbreed with domestic varieties they would cause economic dependence on US corporations. they are considered less nutritious. all of the above.
Answer:
The correct answer is - all of the above.
Explanation:
GMO or genetically modified organisms are organisms that are genetically engineered to alter their genetic material, DNA, in order to increase or improve the quality of the organism. The products are produced by these organisms are produced are known as GMO foods or products.
Such products have many reasons that these products are banned to many countries and many countries in Europe or Africa. The major reasons are-
These foods lead to local agriculture economy as there would be better food products in less price, these products will increase the dependency on the USA for such products. Many consider these products are less nutritious.
How does geography influence climate?
Answer:
Geography affects the weather in many ways. ... Topographical features like mountains affect the weather mostly in the way that they direct air currents. For example, air is forced to rise over mountains. Moist air will cool as it rises, and then the clouds release the water, causing precipitation like rain or snow.

Before cellular division, the cell must duplicate its DNA so that the daughter cells will contain complete copies of the dna. Which characteristic of DNA makes it most suitable as a molecule for this role?
A. DNA is located in the nucleus
B. DNA is a large macromolecule
C. DNA is made of repeating sugar-phosphate subunits
D. DNA is made of two strands of complementary nucleotides
Answer:
D. DNA is made of two strands of complementary nucleotides
Explanation:
As rightly stated in this question, DNA replication must occur prior to cell division because each daughter cells must receive an equal and correct amount of genetic material (DNA). DNA replication is the process by which the DNA molecule duplicates to form two identical copies of itself.
This replication characteristics of DNA is achievable because "DNA is made of two strands of complementary nucleotides". The double-stranded DNA first unwinds into two single strands. After which, each single strand serves as a template for the new DNA strand. Two strands of a DNA molecule are complementary to one another.

how does reducing gene flow cause speciation
Answer:
reduction of gene flow can occur due to geographical isolation too
or it can be dur to sympatric or allopatric speciation an occur.
where due to this the species are being behaviouraly isolated, and mad too reject mating due to certain reasons. Moreover mutations too can take palace causing for a genetic drift. Where the isolated species may undergo selection pressure too. So as an overall view the gene flow eventually decreases since the species diversity along with the genetic diversity decreases causing fare the reduction of the gene pool.
After many generations a new species will be formed. Resulting for speciation.

-What genotypes would the parents have to be to have a child with hemophilia?
Answer:
If the father has hemophilia and the mother DOESN'T the daughters any will have and the sons won't. If the moms have it and the dad doesn't that means all of the sons will have it and the daughters won't
Explanation:
Mark as Brainliest
Answer:
Male/Dad: XhY
Female/Mom: XHXh
Explanation:
Hemophilia is a sex-linked recessive disorder. Due to this, this means that the genotypes of those affected would be:
XhXh (female)XhY (male)Doing a quick punnet square using XhY x XHxH would equal to 25% XHXH (unaffected female), 25% XHXh (female carrier), 25% XHY (unaffected male), 25% XhY (affected male).

An increase in ocean salinity can increase ___, creating a current.
density
the Coriolis effect
wavelength
Answer:density
Explanation:
An increase in ocean salinity can increase density which results in creating a current. The correct option is A.
What is salinity?The concentration of dissolved salts present in water is meant to refer to as salinity.
In seawater, sodium and chloride are the most abundant ions, but magnesium, calcium, and sulfate ions are also present in significant concentrations.
An increase in ocean salinity can increase density which results in creating a current.
Thus, the correct option is A.
