Answer:
Due to inability to survive in aerobic condition.
Explanation:
The strain dies when exposed to a normal laboratory atmosphere instead of nitrogen gas atmosphere because the mutation causes change in the capability of the strain to survive in the aerobic conditions. This mutation inactivate several enzymes which is also responsible for their capabilities of surviving under both anaerobic and aerobic environment so that's why the strain dies when exposed to normal atmosphere..
Answer:
There is no effective cure.
the disease is caused by a single defective gene on chromosome 4.
the disease causes a breakdown of nerve cells in the brain.
as early as age 2 or as late as 80. but usually 30 and 50.
molecular analysis, i don't know the last words sorry
Answer:
The incorrect conclusion is D that is finding burial sites of <em>Homo habilis </em>on different countries.
Explanation:
<em>Homo habilis</em> are called as stone age human that are appeared between 2.1 and 1.5 million years ago and they use tools that are made up of stone which they use to kill the animals. They are called as scavengers and they didn't have any knowledge about bury the dead bodies.
<em>Homo neanderthalensis</em> are the extinct species of human that appears at about 40,000 years ago who bury the dead body but they became extinct due to competition and they did't able to adopt the modern techniques.This was the prime factor that they became extinct.
The pH will decrease because lemon juice is very acidic meaning it would bring the pH level down to a more acidic value.
Answer choices:
- A frame shift mutation in the X chromosome of a cheek cell
- A chromosomal mutation in the Y chromosome of a kidney cell
- A point mutation in the first chromosome of a sperm cell
- A substitution mutation in the third chromosome of a uterus cell
Answers:
A point mutation in the first chromosome of a sperm cell
Explanation:
Only mutations that affect the germ line are passed on to the next generation. Therefore, only mutations in the egg and sperm of an individual have the potential to affect the next generation.
Mutations in cheek cells, kidney cells, and uterus cells might cause cell death or cancer. This genetic material is not passed on to the next generation, only the egg and sperm contribute this material. Therefore, only mutations here will affect the generation.
