Which of the following steps has not yet been accomplished by scientists studying the origin of life?

Biology
1 answer:
EastWind [94]3 years ago
3 0

Answer:

The correct answer is option c. "formation of protocells that use DNA to direct the polymerization of amino acids".

Explanation:

The polymerization of amino acids is a complex biological function that involves multiple proteins and cofactors working together at different locations in the cell. Even though there are some scientific advances in the production of synthetic protocells (cell like structures made from synthetic particles), the formation of protocells able to synthesize amino acids from DNA directly has not been accomplished.

Can we create effective vaccines or immunizations for lab made viruses? Or is it not possible because of the synthetic/man-made
Rashid [163]

Yes, it is possible to develop effective vaccines for any type of viruses. Genetically engineered viruses exhibit similar characteristics to natural viruses.

<h3>What is a virus?</h3>

A virus is a genetically independent entity that needs a suitable host to reproduce its genetic material (either DNA or RNA).

A genetically engineered virus is a virus whose genetic material has been modified using genetic engineering techniques.

Vaccines can be developed for removing any type of viruses because they take advantage of the intrinsic properties of the immune system (i.e., antigen recognition), independently of its origin.

Which type of pollution occurs when small particles of soil are suspended in water
Blizzard [7]

Answer:

Physical Pollution

Explanation:

Physical Pollution is the type of pollution which occurs when small particles of soil are suspended in water. The small soil particles do not mix with the water but are rather suspended thus reducing the amount of light energy availed to micro-organisms in the water.

Physical pollution is the type of pollution that is caused by color change, suspended solids, temperature conditions or radioactivity.

Identify the phenotypes for the offspring of a parent with the genotype IBi and a parent with the genotype IAIA. type O type A,
agasfer [191]
 <span>I is dominant, i is recessive. The A's and B's are just show which allele I is. When there is just one dominant allele, it masks the recessive in blood typing. Remember IA and IB are codominant. 

O is always ii 
A is IAi (heterozygous) or IAIA (homozygous) 
B is IBi (heterozygous) or IBIB (homozygous) 
AB is always IAIB 

Remember: You get one allele from each parent! 

1. Father must be ii, mother must be ii, so all children must be ii. 

2. Father is IAIA (the homozygous one), the mother is IBIB, so the only possibility for the children is IAIB, because you get one allele from the father and one from the mother. 

3. Father is IAi, mother is IBi, so the children can be any of the blood types, because they can have all the combinations of genotypes. 

4. Father is ii, mother is IAIB. Children can only be IAi or IBi. 

5. Father is IAIB, mother is IAIB. Children can be IAIA, IBIB, or IAIB. 

Example of Punnett square: 
3. Father is type A, heterozygous, mother is type B, heterozygous 
Father must be IAi (heterozygous) 
Mother must be IBi (heterozygous) 

_______IA ____ i 

IB____ IBIA____IBi 

i _____ IAi______ii 

Sorry, that was difficult on here, hope it's understandable. 
The father's alleles run across the top, the mother's are on the side, you follow to where they meet to find the possibilities for the children. IBIA (AB blood type), IBi (B), IAi (A), and ii (O) are the possibilities in this case. 

Hope that helps!</span>
