Answer:
human embryonic stem cells are obtained from embryos, thereby they are subject to ethical, religious, political and legal considerations
Explanation:
Human embryonic stem cells (HESCs) are pluripotent undifferentiated cells derived from blastocyst-stage embryos, which have the ability to produce any type of somatic cells. HESCs are obtained <em>in vitro</em> from embryos that are 5-6 days old. These cells are valuable tools in research in order to understand the genetic and physiological mechanisms of human development, as well as to develop treatments against diseases. The use of embryonic stem cells in research is controversial because these techniques involve the destruction of human embryos, and there are people who consider human life begins with the formation of the diploid zygote after fertilization, thereby raising the debate if a human embryo can be regarded as a human being.
The genotype of the mother must be heterozygous.
<h3>Punnet' square</h3>
In order to obtain a probability of 25% red-eyed males from the offspring, the mother must be heterozygous for the trait. The father can be of any genotype.
Thus, the likely genotype combination that will result in 25% red-eyed males are:
x 
- and
When you cross the first one above, the genotype of the offspring would be 
.
The second cross will give offspring with the genotypes 
Both crosses give a 25% chance of producing re-eye males.

Answer:
A neuron's nucleus is located in its CELL BODY
A nerve impulse moves toward a neuron's cell body along AXON
Explanation:
A neuron consists of three major parts: cell body, dendrite and the axon.
1) The cell body consists of the nucleus and cytoplasm
2) Dendrites are short cytoplasmic filaments which conduct impulses towards the cell body
3) Axon is made up of a single, long fibre which transmits impulses away from the cell body
