Answer:
genetically identical somatic cells containing 46 chromosomes
Explanation:
Human somatic cells are composed of 23 pairs of homologous chromosomes, therefore they are composed of a total of 46 chromosomes.
Mitosis is a process of cell division. In humans this process originates from a a single mother diploid cell (46 chromosomes) , two diploid -and genetically identical- daughter cells. It is, two daughter cells each with 46 chromosomes
The daughter cells in mitosis are identical because, unlike the meiotic cell division, where haploid gametes are produced, <u>there is no genetic recombination in mitosis</u> and therefore there is no difference in the cells resulting from mitosis.
Answer:
answer is c
Explanation:
The cell needs a lot of preparation and checks in G1, S and G2 to do mitosis. especially in the G1 phase which is the longest phase. It is explained by the fact that the cell should "rest and recover" after the last mitosis before getting into the second one
In the area of tissue and organ bio-engineering, scientist have been able to create simple tissues like cartilage. However, they are yet to accomplish in creating complex organs such as heart and lungs. There are many complications while creating heart, lungs and kidney because they have complex structure, different types of cells and also varied functions.
However, creation of windpipe is an achievement as many infections can be cured. Thus, tissue engineering is an emerging branch of science which also needs advanced technology and huge investment.
Answer:
B.
Explanation:
A recessive gene is a gene that can be masked by a dominant gene.
