Diploid plants have two sets of chromosomes. Polyploid plants have more than two sets of chromosomes, are often larger, and have more desirable characteristics. To create polyploid plants, plant breeders can treat diploid plants with a chemical that prevents the separation of sister chromatids during mitosis. Resulting cells that have any partial chromosome sets, even if in addition to one or more complete chromosome sets, typically do not survive this process.

If a diploid plant cell treated with such a chemical goes through a single round of mitosis, what is the MOST LIKELY genetic composition of the resulting cells that survive?

Answers

Answer:Both haploid and diploid cells can undergo mitosis. When a haploid cell undergoes mitosis, it produces two genetically identical haploid daughter cells; when a diploid cell undergoes mitosis, it produces two genetically identical diploid daughter cells.

Answer:

its b

Explanation:

To produce a tetraploid plant, the alkaloid colchicine is applied to the terminal bud of a branch. All the cells in the developing branch will be tetraploid (4n) with four sets of chromosomes. This includes cells of the stem, leaves, flowers and fruit. Gametes (egg and sperm) produced by a flower on this tetraploid branch will be diploid (2n) with two sets of chromosomes. A flower on the normal diploid (2n) branch will produce haploid (n) gametes containing one set of chromosomes.

Stages of mitosis in the formation of tetraploid cells. The original mother cell is diploid (2n). During anaphase the chromatids separate and move to opposite ends of the cell. Colchicine causes the dissolution (depolymerization) of protein microtubules which make up the mitotic spindle in dividing cells. This leaves the cell with twice as many single chromosomes (four sets rather than two). When this cell divides, each of the two daughter cells will have fours sets of chromosomes, a total of eight chomosomes per cell. [Note: Spindle poisons such as colchicine are used to prevent tumor cells from dividing in certain chemotherapy treatments.]

The botanical term parthenocarpy refers to the development of the ovary of a flower into a fruit without fertilization. [The biological term parthenogenesis refers to the development of an egg without fertilization.] Fruits that develop parthenocarpically are typically seedless. Some seedless fruits come from sterile triploid plants, with three sets of chromosomes rather than two. The triploid seeds are obtained by crossing a fertile tetraploid (4n) plant with a diploid (2n) plant. When you buy seedless watermelon seeds, you get two kinds of seeds, one for the fertile diploid plant and one for the sterile triploid. The triploid seeds are larger, and both types of seeds are planted in the same vicinity. Male flowers of the diploid plant provide the pollen which pollinates (but does not fertilize) the sterile triploid plant. The act of pollination induces fruit development without fertilization, thus the triploid watermelon fruits develop parthenocarpically and are seedless. Most bananas purchased at your local supermarket came from sterile triploid hybrids. The fruits developed parthenocarpically and are seedless.

Answer:

Types of Symbiosismutualism - a mutually beneficial symbiotic relationship.commensalism - a one-sided symbiotic relationship.parasitism - one species lives on, in or with a host species.competition - relationship in which organisms compete for resources.

Answer=

Mutualism, commensalism, and parasitism are the three forms of symbiosis. Symbiotic connections are classified into one of these categories based on the nature of the interaction between organisms. Mutualism is a positive connection in which both species gain from one another.

Explanation:

Disruptive selection is DISRUPTIVE to an ecosystem, making the ecosystem scarcer of extreme traits. Also, a BELL-shaped pattern, where a line slopes upward and then back down, would represent a population that is mostly above average, since the climax is a maximum instead of a minimum.

Succession on land that did not previously have plants, such as soil exposed as a glacier retreats or a new sand bar in a river is called primary succession.

It takes over 600 years to primary forest succession to reach the climax. it includes breakdown of the rocks into soil and plants help in survival of different animal and progress from primary succession to the climax community.

5. Which of the following best describes the effect of coral bleaching on corals?
A. As temperatures increase, corals lose symbiotic algae, which provide most of their habitat
B. As temperatures decrease, corals lose their symbiotic algae, which provide most of their energy.
C. As temperatures increase, corals lose their symbiotic algae, which provide most of their energy.
D. As temperatures increase, corals gain symbiotic algae, which hinder their ability to conduct photosynthesis.

Answers

As temperatures increase, corals lose their symbiotic algae, which provide most of their energy. This is the best description to the effect of coral bleaching on corals. Thus, the correct option is C.

What are coral reefs?

A coral reef is an underwater ecosystem which is characterized by the reef-building corals. Bleached corals are found in the underwater ecosystem which most likely show reduced growth rates, decreased reproductive capacity, increased susceptibility to diseases, and elevated mortality rates than the normal coral reefs. Changes in the coral community composition can occur when the more susceptible species are killed by bleaching events in the ecosystem.

When the conditions such as the temperature change, corals are expelled out the symbiotic algae which is living in their tissues, it is responsible for their colour. A spike of the temperature to 1 to 2°C in the oceans sustained over several weeks which can lead to bleaching, that turns corals white. If the corals are bleached for prolonged periods of time, they eventually die.

Therefore, the correct option is C.
