Answer:
2. The US uses far less renewable energy than most other countries.
Explanation:
US uses very less renewable entgy in comparison to other countries because of several reasons such as:
- overall cost of renewable energy is very high.
- limitations to geography.
- can cause pollution, such as biomass.
- fossil fuels are more reliable as do not depend on other environemntal fluctuations such as solar light.
Hence, the correct option is 2.
Answer: A. independent assortment
D. Lipids, Specifically Animal Fat
Reasoning - Behind the Lipids is that the chemical bonds can break faster and provide formula for the breakdown.
Answer:
Deletion mutation usually takes place due to the errors in the process of DNA replication . DNA polymerase slips off on the template strand due to which that part of the DNA is not coded in the daughter strand.
It can skip from one nucleotide (point mutation) to an entire gene. Point deletion can result in frame-shift mutation if it takes place in the beginning or middle of the gene. However, if it takes place at the end of the gene then it may cause no harm.
For example, let us assume the original sequence of DNA as ATG-AGT-CGT-ATA-TAA. It will result in the formation of methionine, serine, arginine, isoleucine, and STOP codon.
Point deletion at the end of the gene results in ATG-AGC-GTA-TAT-AA sequence. Now it will code for methionine, serine, valine, and tyrosine as AA will not code for anything. Hence, the sequence of the protein remains the same.
Hence, if deletion mutation takes place at the last or stop codon of the gene then it will cause no harm or change in the protein sequence. However, if it takes place before that then it may result in frame-shift mutation and thus a mutated protein.
Answer:
Explanation:
A mutation in DNA alters the mRNA, which in turn can alter the amino acid chain.
