Answer:

B. Meiosis produces four new cells. is the correct answer.

Explanation:

Meiosis different from mitosis because Meiosis produces four new cells whereas mitosis produces two diploid cells.

Mitosis is a type of cell division which results in the formation of two genetically identical daughter cells from the single parent.

Meiosis is a kind of cell division that results in the formation of four daughter cell and chromosome number get reduce to half of the parent cell that is from diploid to haploid.

The function mitosis is cell repair, regeneration and growth whereas the function of meiosis is to produce gametes for sexual reproduction.

Marina CMI [18]

Answer:

Water pollution may be defined as the contamination of the unwanted substance or pollutant with water that changes the normal characteristics of water. Three main contributors of ground water are as follows:

Chemical farming: The use of pesticides and fertilizers in the fields and its direct run off in river and groundwater causes the water pollution.

Industrial waste: The industrial waste consists of harmful chemicals and heavy metals. The direct discharge of chemical waste in the lakes, ground water and ponds makes the water dirty and causes water pollution.

Effluent from waste water treatment plant: The effluent and the harmful chemical waste release from the waste water treatment plant is the major contributor to the ground water. The effluents mix with the ground water and changes the ground water property.

Gnoma [55]

<h2>Homologous</h2>

Explanation:

Two or more species share a unique physical feature, for example, an unpredictable bone structure or a body plan, they may all have acquired this component from a typical predecessor.
Physical highlights shared because of developmental history (a typical progenitor) are said to be homologous.
The front flippers of whales and the forelegs of four-legged vertebrates like canines and crocodiles are completely gotten from the equivalent tribal tetrapod structure.

Two people are exercising at a gym. Person X notices a burning sensation in several muscles, while person Y does not feel any di

Alex Ar [27]

Answer:

See the answer below

Explanation:

Person X is feeling a burning sensation in several muscles because of the accumulation of lactic acid due to inadequate oxygen in their system. When oxygen becomes inadequate during exercises, anaerobic respiration takes place to augment the oxygen shortage and this leads to the production of lactic acid which accumulates up in the muscles and gives a burning sensation.

$C_6H_1_2O_6 --> 2C_3H_6O_3$

Person Y does not feel any burning sensation in their muscles because oxygen is adequate in their system and they do not need to respire anaerobically. Person X exercise regime must have been more rigorous than that of person Y.

Anna71 [15]

The correct answer that would best complete the given statement above would be A TWO-HEADED FLY. A high concentration of bicoid protein at the opposite ends of a developing drosophila embryo would result in the development of a two-headed fly. The bicoid gene is a type of egg-polarity gene and is transcribed by nurse cells.
