Stem cells are undifferentiated cells that could develop to perform a variety of tasks. One type of stem cell is the embrionic stem cell. There are also adult stem cells. To use embrionic stem cell you need to have fertilized embrios. These can be donated to research. The use of the embrionic stem cells is controversial for this reason.
Answer:
8 chromosomes in each daughter cell
Explanation:
Mitosis creates identical cells. If there are 8 chromosomes in the parent cell, there will be 8 chromosomes in each daughter cell. The way it works is that in late Interphase, the number of chromosomes and DNA double. In this case there would be 16 chromosomes. And when the cell splits into two during cytokinesis, each of the two would get half the chromosomes. Hence, there would be 8 chromosomes in each daughter cell.
Answer: The options are not included.
But the sites are;
Interaction with ribosomes.
Interaction with aminoacyl tRNA
synthase.
Attachment of the specific Amino acid.
Interaction with codon.
Explanation:
Transfer RNA is a type of RNA that help to translate messenger RNA sequence into protein. Each tRNA have two major areas; the anticodon and region for attaching specific Amino acids.
tRNAs function at specific sites in the ribosomes during mRNA deciding.
The four specific recognition sites of trna that must be inherent in it's tertiary structures in order for it to carry out it's role are;.
Interaction with ribosomes.
Interaction with aminoacyl tRNA synthase.
Attachment of specific Amino acid.
Interaction with codon.
The evidence supporting the idea that modern birds and reptiles share a common ancestor is that feathers are a derived characteristic that first evolved in reptiles. Feathers represent an evolutionary derived trait.
In evolutionary biology, an autapomorphy is a distinctive phenotypic trait referred to as a derived trait, which is unique to a particular group/taxon.
The derived traits are phenotypic features that arise during the evolution of a particular taxonomic group.
These traits (derived traits) differ from the phenotypic trait of the ancestor of the group.

Answer:
Over all growth and development cycle
Explanation:
<em>C. elegans,</em> due to its manageability, nervous system, muscle, skin gut and reproductive cycle makes it an ideal model. These nematodes are similar to human systems and lot of the research found can be applied to humans and medicine.
Apoptosis is the programmed cell death and this can be for many reasons such as repair, replace or removal of old or damaged cells. This groundbreaking research has captured the attention of scientist over the decades and many new findings are continuing to evolve.
Some phenotypes that are important in studying apoptosis are: Stress response, growth and development, tumor formation/regeneration and wound healing.
