Answer:

The answer is "Sympatric speciation due to disruptive selection"

Explanation:

Disruptive selection is a certain type of natural choice, that aggressively favors all ends of the spectrum in a moderate community. Disruptive selection is often deduced by a phyletic prepared to change to contribute to speciation. These two species happened due to various habitats associated with extreme speciation due to various confusing choices.

Answer: The symbiotic nitrogen-fixing bacteria invade the root hairs of host plants, where they multiply and stimulate formation of root nodules, enlargements of plant cells and bacteria in intimate association. Within the nodules the bacteria convert free nitrogen to ammonia, which the host plant utilizes for its development. brainliest?

Answer:

The correct answer is - health hazards (carcinogenic).

Explanation:

Processed foods, cured meat, and certain types of wines have a chemical present in them for increasing the life of the food and taste. This chemical is used in this food are known for their cancer-causing properties and grouped as group 1 carcinogen which comes under health hazard of type of chemical hazard.

N-nitroso-compounds (NOC) and polycyclic aromatic hydrocarbons (PAH) are the two major chemicals used in cured meat and processed food. There are many other severe health conditions also caused by ingesting a high amount of such food like diabetes, cardiovascular disease, and obesity.

Explanation:

DNA is created by the DNA polymerase and unzipped by the DNA helicase.

DNA stands for deoxyribonucleic acid.

DNA is defined as a collection of molecules that are in charge of transporting and passing genetic information from parents to children.

It can also be defined as a sophisticated molecule that carries all the data required to create and maintain a creature.

There are basically two types of DNA.

Today, DNA serves three unique purposes: genetic, immunological, and structural, all of which depend in different ways on the sugar phosphate backbone and the bases.

Replication, information encoding, mutation/recombination, and gene expression are the four functions that DNA performs.

Thus, DNA is created by the DNA polymerase and unzipped by the DNA helicase.

Answer:

5.) The possible genotypes should be: RR RB BB ( if the could for the same proteins)

6.) Frequency of R: 0.5

7.)Frequency of R: 0.5

8.)Frequency of R: 0.375

Explanation:

5.) If R and B code for the different forms of the same protein then they are only a few possible out comes

6.) First calculate the total alleles in population

allele R= 40

Allele B=40

total allele = R+B= 40+40

=80

Now to find allele R frequency is:

(Total R alleles) / (Total allele in pop)

40/80=

0.5

7.)Calculate the total alleles

Alleles from for R

RR= 10

R=10x 2= 20

Multiply the value by 2 because there are 2 R alleles present in

RB=20

R=20

Number doesn't change there is only 1 R allele

Total R=20+20

=40

Alleles For B

BB=10

B=10×2

=20

Same thing here, two B alleles together so multiple by 2

RB=20

B=20

Total B= 20+20

=40

Total alleles in pop add

40+40

=80

Frequency of R

Total of R/Total Alleles

=40/80

=0.5

8.)Repeat the same thing in 7 but use different numbers

RR=10

R=10x2

=20

RB=10

R=10

Total R= 20+10

=30
