B. Flowers give greater access to sunlight
C. Flowers help transport water and nutrients
D. Flowers assist plants that live in the water
The advantage of flowering plants is Flowers attract insects that transport gametes.
Because they are often showy and endowed with nectaries, the flowers of angiosperms attract animals, such as small invertebrates, birds and bats. Such living beings, when coming into contact with several flowers of the same species, provide the meeting of pollen grains with female reproductive structures.
Flowers help to maintain air quality. They are natural humidifiers purifying the place and releasing oxygen. They also work as aromatizers by exhaling their fragrances.

#SPJ2
Answer:
See the answer below
Explanation:
At the G2 checkpoint, the accuracy of chromosome replication is assessed along with the cell size and proteins within the cell. The cell division will only proceed if all the listed conditions appear all right.
At the M checkpoint, the correct attachment of spindles to the kinetochores of the sister chromatids of each chromosome is assessed. This is to ensure that chromosomes are correctly separated to the opposite poles of the cell.
asexual reproduction
this is the correct answer
transforming the energy in glucose and related molecules in a chemical form that cells can use for work best describes the main purpose of the combined processes of glycolysis and cellular respiration .Thus option B is correct.
A metabolic process in which a series of steps occur to convert chemical energy (sugar) into ATP in the cell.
The first stage is glycolysis, which breaks the glucose molecule into two smaller molecules called pyruvate, and releases small amount of ATP energy and it is oxygen independent.
second stage where reorganization of pyruvate molecules and fused over again in a cycle, carbon dioxide is formed and electrons are removed.
These electrons placed in an electron transport system release ATP for the plant to use for growth and reproduction and this process is oxygen dependent.
Thus option B is correct.

Cloning is a process of making geneticallyidentical copiesof a cell. In eukaryotic organisms, cloning is done through mitosis. So the correct answer is Option B.
When a cell replicates itself without altering its genetic makeup and producesidentical copies which are similar to the original cell, then the cell is said to undergo cloning.
In prokaryotes, such as bacteria, binary fission, and budding are used to make copies of the cells while in eukaryotes, cloning of cells is done through a cell division process known as mitosis.
Mitosis is also called equatorial division. This is because the chromosomes are replicated and distributed equally between the clones. Cloning occurs naturally during the birth of identical twins but it can be performed artificially in the laboratory by providing the similar condition necessary for cloning.

Answer:
The correct answer would be B) Mitosis.
Mitosis refers to the division of a cell which results in the formation of two daughter cells, each having identical genetic material as present in the parent cell.
The cells produced are identical to each other in terms of genetic information, structure, as well as the size and thus they are termed as a clone.
Mitosis is used by most of the cells (except gametic cells) for their division. In a cell or tissue culture also, cells undergo mitotic division to divide and grow.
Thus, cloning can be added to the mitosis.
