Which organism will have DNA most similar to the turtle?

Answers

Answer:

the answer is leopards!

Explanation:

I answered a similar question like this yesterday,

Hope it helps!!

The organism that will have DNA most similar to the turtle's will be other reptiles, particularly those in the same order as turtles, which is Testudines, which is present in Option A.

What is DNA sharing among ancestors?

Organisms that are closely related evolutionarily tend to have more similar DNA sequences than those that are more distantly related because they share a more recent common ancestor and have had less time to accumulate genetic differences. Turtles belong to the class Reptilia, which includes other reptiles like lizards, snakes, crocodiles, and birds. Within the reptile class, turtles are classified under the order Testudines, and other members of this order include tortoises and terrapins that share common characteristics with turtles.

Hence, the organism that will have DNA most similar to the turtle's will be other reptiles, particularly those in the same order as the turtles present in Option A.

The gravitational force between two objects will be very small, unless...
Group of answer choices

the objects are very far apart

the objects have very large masses

the objects are in the solid state of matter

the objects are spinning

Answers

Answer:

the objects have very large masses or an object in circular orbit. This has motion but its always being to pulled to earth by gravity.

Greater gravitational forces will be used to attract heavier things, since the gravitational force is directly proportional to the mass of both interacting objects. Two objects are attracted to one another by gravity as their respective masses increase. Thus, option B is correct.

What is the role of large masses in gravitation force?

The gravitational pull between two objects changes inversely with their squared distance and directly with their large masses.

As a result, the gravitational force between the two items would decrease to one-fourth of its initial strength when the large masses of both objects are halved without affecting their distance.

Therefore, The objects are either in a circular orbit or have extremely  large masses. Although something is moving, gravity is always bringing it dangerously close to the ground.

Tissue is a group of cells that have similar structure and that function together as a unit. primary types of body tissues include epithelial, connective, muscular and nervous tissues. Epithelial tissues form the covering of all body surfaces , ine body, cavities and hollow organs, and are the major tissues in glands.

A tissue is composed of a group of cells that are determined to play a specific function. The Cytoplasm is a dense gel-like material that is filled within the cell.

What is Cell theory?

Cell theory was proposed by M. Schleiden and T. Schwann in 1838. According to them, there are three postulates of cell theory that are as follows:

All living organisms whether plants or animals are made up of cells.A cell is the smallest unit of all living organisms.The cell is the structural and functional unit of life.

Cell theory was further refined by German biologist Rudolf Virchow in 1855. According to him, all cells are arising from pre-existing cells. The Cell wall generally protects the cell and it is most commonly found in plants, animals, bacteria, etc.

Inside the cell, there are various organelles present that perform specific functions for the survival of the cells. The nucleus is known as the brain or controlling center of the cell, which transmits genetic information from one generation to the next.

Answers

Answer:

D. Due to the availability of solar energy, Diatom mass peaks in July.

Explanation:

Diatom are the photosynthetic algae which prepare food for themselves from the solar radiation just like plants. These diatoms produce more biomass or vegetation in the summer season mainly in July because availability of more sunlight in the Barents sea region while on the other hand, less biomass in the winter season due to low temperature and solar radiation which also effects the population of zooplankton organisms. So we can conclude that seasonal changes have a great impact on the organisms living around the Barents Sea.

The blue people of Troublesome Creek Kentucky were genetically isolated from the rest of the world for generations. A rare recessive allele that causes people to have a blue tone to their skin, methemoglobinemia, became disproportionately common within this population by way of their genetic isolation. In the last few decades new roads opened leading to the end of this communities isolation. To the surprise of many, the methemoglobinemia phenotype disappeared along with their genetic isolation. Which of the following may best explain the apparent disappearance of this once common trait?

a. Methemoglobinemia did not confer any physical advantage so that the trait was selected against.
b. Methemoglobinemia was probably lethal and all those that carried this trait died and did not have a chance to pass on this trait to future generations.
c. Those that had the traits simply did not have descendents.
d. With the end of genetic isolation gene flow took place.

Answers

Answer:

The correct answer would be - d. With the end of genetic isolation gene flow took place

Explanation:

It is given that people of Troublesome Creek Kentucky were isolated and have a rare recessive allele that results in a blue tone to their skin. However, later these isolated people connected with the people from outside, and due which allow them to intermate. Intermating among populations from isolated and people from outside leads to gene flow.

Methemoglobinemia was present in the isolated population as they had both recessive alleles in their genotype and other hand people from outside might have heterozygous or both dominant allele genotypes that make them free from this disorder.

Due to the intermating and gene flow, the number of heterozygous conditions rises and after many generations slowly methemoglobinemia could have disappeared due to the masked recessive allele.

Homologous recombination occurs in a heterozygote in which alleles D and d differ by a single base pair. The D allele has a G (a GC base pair) at one position, whereas the d allele has a C (a CG base pair) at the same position. If branch migration causes heteroduplex formation across this position, what is the expected outcome

Answers

Answer:

Mismatch DNA repair mechanism recognizes the abnormal base pairing (G-G base pair) and may correct it by converting the D allele to d

Explanation:

The DNA mismatch repair can be defined as a specialized mechanism that recognizes and repairs errors in the nuclotide sequence (such as, for example, bases erroneously incorporated) during DNA replication and recombination. The DNA mismatch repair is a system that also acts to repair the DNA after damage. It has been shown that the DNA mismatch repair mechanism leads to the generation of a DNA molecule with one chain that has the nucleotide sequence arising from DNA repair and one parental chain. In this case, it is expected that the DNA mismatch repair mechanism will identify the abnormal G-G base pairing and then this system may change the D allele to a d allele by introducing a C base instead of a G base in the DNA strand.
