Answer: Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
By the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. The overall process of meiosis produces four daughter cells from one single parent cell.
Explanation:
During meiosis, homologous chromosomes (1 from each parent) pair along their lengths. The chromosomes cross over at points called chiasma. At each chiasma, the chromosomes break and rejoin, trading some of their genes. This recombination results in genetic variation.
Answer:
archaea
Explanation:
i think cause they have its cells
Respiration is process where plant produce heat
Explanation:
Respiration is essential component for every living thing this. Respiration help living thing get energy and stay alive. In plant cellular respiration is used to convert nutrient which is present in soil and this process can be understand as a cellular activity. In plants seeds play vital role.
The basic difference between respiration and photosynthesis is in respiration plant consume nutrient for survival and alive plant cell but in photosynthesis plant is able to make their own food. In respiration only plant produce heat energy
<u>The formula of Respiration:
</u>
Oxygen + glucose – Carbon dioxide + water + heat energy
<u>The formula of Photosynthesis
</u>
Carbon dioxide + Water + Sunlight – Oxygen + glucose
