Answer:
The essential factor to increase the number of cells in a growing organism is that each and every cell has a complete copy of DNA.
Explanation:
The development and growth of an organism is based on the multiplication of its tissue cells. Cell multiplication in somatic cells occurs through mitosis, a process that allows obtaining<u> two identical daughter cells from a progenitor cell</u>.
DNA contains all the genetic information belonging to a living organism. In the process of mitosis, the DNA of each cell must be replicated so that each daughter cell has a complete copy of the original DNA. This ensures that each cell resulting from mitosis has the same structure and function as the original cell.
The other options are not correct because:
- <em>The </em><u><em>size of the cell is important</em></u><em>, since each cell has defined characteristics, according to the tissue it must form.
</em>
- <u><em>Each and every cell needs to have a complete DNA</em></u><em>.
</em>
- <em>In somatic cells, </em><u><em>DNA does not vary from one cell to another</em></u><em>.</em>
Answer:
It never can produce its own food photosythetically
Explanation:
Euglenas can obtain food either autotrophically (by photosynthesis) or heterotrophically, depending on environmental conditions. Thus, it does not always perform photosynthesis.
Answer:
The correct answer is - 50 % or 1/2 chances.
Explanation:
As it is given that the father of the man with syndactyly had normal father which is only possible if he had two recessive alleles as it is an autosomal dominant condition, therefore, it also means the mother of man must have one or two dominant alleles for the disease and one is passes to the man, so the man is heterozygous for the diseases gene.
Man - Ss married to a normal woman which means she has both recessive alleles that is ss.
S s
s Ss ss
s Ss ss

If the animals didnt exist in the forest the forest wouldn't exist so that's why when an animal goes extinct it affects the ecosystem dramatically
