The provided question is incomplete, however, the question asked is a very generalized question, answering it on the knowledge of mitosis.

Answer:

The correct answer is - mitosis has a great role in the growth of plants.

Explanation:

Mitosis is a type of cell division that occurs in the somatic cells of an organism. During mitosis, a parent cell divides into two daughter cells with the same number of chromosomes. There are no recombination takes place. This type of cell division is fast.

Mitosis occurs during asexual reproduction in the form of budding, propagation as well as repairing of the cells as they are fast, such as the regeneration of new cells. The growth of plants and development is dependent on mitosis as they produce cells more efficiently and fast and mitosis is the only cell division found in somatic cells.

Describe the role of the carrier molecule nadp in photosynthesis
Eduardwww [97]

Answer:

The high energy electrons from chlorophyll to other molecules are transferred by this molecule.

Explanation:

NADP is an important molecule which is used in the production of energy in the form of ATP. During the process of photosynthesis it acts as a universal electron carrier. It accepts electrons and hydrogen atoms to form NADPH. NADPH then moves to the other location of reactions and there it donates the energy stored in bonds along with hydrogen and electrons to other molecules and again becomes NADP.

noname [10]

Answer:

Alfred Wegener

Explanation:

Continental drift was a theory that explained how continents shift position on Earth's surface.

g Two closely related species of plant (A and B) hybridize to form a new species (C). Species A is diploid and has 8 chromosomes
Aleks04 [339]

Answer:

allopolyploidy

Explanation:

Polyploidy is the condition by which a cell might have more than two chromosome sets that form homologous pairs. It might occur due to a failure or abnormality in cell division.  

Autopolyploidy

Refer to a type of polyploidy in which an organism has more than two copies of homologous chromosomes. It results from the duplication of a group of chromosomes of the same species. Autopolyploid individuals have <u>at least three groups of homologous chromosomes</u>. Autopolyploidy is produced by the<u> gamete fusion of the same progenitor - same species</u>-, duplicating the number of chromosomes of diploid species. The autopolyploid cell has groups of homologous chromosomes. Autopolyploidy is produced mainly due to non-disjunction during meiosis.

Allopolyploidy

Refer to another type of polyploidy in which species have more than three sets of chromosomes in their cells. Allopolyploidy <u>occurs when two different species mate</u>, leading to the fusion of gametes that belong to different species and produce a new hybrid. The chromosomic complement has more than two copies of chromosomes. The hybrid is infertile with the parental species. The allopolyploid cells have chromosome groups that are not homologous.  

In the exposed example two different species mate and produce a hybrid species.

While biodiversity includes the number of species in a given area, it also includes:_________
grandymaker [24]

While biodiversity includes the number of species in a given area, it also includes phylogenetic lineages.

<h3>What is biodiversity, exactly?</h3>

The variety of animals, plants, fungi, and even microorganisms like bacteria that make up our natural environment are all included in what is known as biodiversity. These various species and critters collaborate in complicated web-like ecosystems to keep things in balance and support life.

<h3>What kind of biodiversity is that?</h3>

As a group of distinctive living entities having the capacity to reproduce with one another, biodiversity. Blue whales, white-tailed deer, white pine trees, sunflowers, and minuscule germs that are even too small to be seen with the eye are a few examples of species.

<h3>How can biodiversity be preserved?</h3>

Purchasing fewer products and ensuring that the ones you do purchase have a minimal impact on biodiversity investing in initiatives to advance biodiversity.
