Answer:
Embryonic Stem Cell Disadvantages
1. Difficult to differentiate uniformly and homogeneously into a target tissue. 2. Immunogenic—ES cells from a random embryo donor are likely to be rejected. after transplantation.
Explanation:
The main disadvantage with embryonic stem cells is the way that they are acquired. Since human embryos are destroyed during the process of harvesting embryonic cells, this makes the research unpopular with those that believe human life begins at conception and that this life is being destroyed.

Structures that are anatomically similar because they were inherited from a common ancestor are called ____________ structures.
Answer:
Homologous structures
Explanation:
Physical features may be considered homologous or analogous, but what does this mean? Homologous structures are similar physical features in organisms that share a common ancestor, but the features serve completely different functions.

Why is a single base insertion or deletion likely to drastically change how the rest of the genetic code is read?
The genetic code is of utmost importance as a slight change in it can change the characteristics of an organism. Just like that base insertion or deletion can cause shifting of frame and can result in a change of the nucleotide sequence causing mutation.
What are the types of mutation?Mutation is any change in the genetic sequence that can lead to changes in the genome.
It can be of the following types:
Germline mutation: In gametes, germline mutations occur. Other cells in the body experience somatic mutations.Chromosomal alterations: these are mutations that change the structure of the chromosome.Point mutations: it affects only one nucleotide.Frameshift mutations: these are nucleotide additions or deletions that cause a shift in the reading frame.Thus, base insertion or deletion likely to drastically change how the rest of the genetic code is read as it result in frameshift mutation.

Add another bar to the chart that would represent Han
chinese at low altitudes. Pay attention to the height of
the bar and provide a short explanation for your choice.
Assuming height of the bar represents altitude, the bar representing Han Chinese will be shorter compared to that representing Tibetans since Han Chinese live at lowlands.
What is the role of natural selection in evolution in Tibetanscompared to Han Chinese?Tibetans and Han Chinese are thought to originate fro. same ancestors.
However, while the Han Chinese lived in lowland areas, Tibetans split off drom the Han Chinese about 2750 years ago and went on to live in high altitudes.
Natural selection helped Tibetans to evolve to adapt to high altitudes with several mutations occurring in their genes which are mostly related to use of oxygen by the body.
Assuming height of the bar represents altitude, the bar representing Han Chinese will be shorter compared to that representing Tibetans.
