Answer:

The answer to this question is given below in this explanation section.

Explanation:

                    "Alternation of generation"

Alternation of generations is the type of life cycle that occurs in those plant  and algae in the archaeologist and the heterokontophyta that have distinct haploid sexual and diploid asexual stages.In these groups a multicellular haploid gametophyte with n chromosomes alternates with a multicellular diploid sporophyte with 2n chromosomes made up of n pairs.A mature sporophyte produces haploid spores by meiosis a process which reduces the number of chromosomes to half from 2n to n.

Two haploid spores germinate and grow into a haploid gametophyte.At maturity ,the gametophyte produces gametes by mitosis which does not alter the number of chromosomes.Two gametes from different organism of the same species fuse to diploid zygote,which develop into a diploid sporophyte . This cycle from gametophyte to sporophyte in the way in which all land plant and many algae undergo sexual reproduction.

Sindrei [870]

Answer:

As the ice melts in the arctic regions, the arctic sea levels and the other oceans stay the same. The weather however changes when this happens and results to the Greenland's melting ice sheet adding another 20 feet to sea level rise.

In summary, the melting of polar ice caps effects would result in sea levels rising around 220 feet or more worldwide.

This will lead to destruction of lives, houses and properties due to water submersion.

Cellular respiration and fermentation both. . A. begin with the breakdown of glucose in glycolysis. . B.produce the same number
Rus_ich [418]

The correct answer is:

A. begin with the breakdown of glucose in glycolysis.

Explanation:

They both begin with a sequence of reactions known as glycolysis, which breaks glucose particles into smaller pyruvate molecules. They are also related in that through both processes, ATP is generated for the cell to use. Glycolysis is the metabolic pathway that transforms glucose C6H12O6, into pyruvate, CH3COCOO− + H+. The free energy delivered in this process is applied to form the high-energy molecules ATP and NADH .
