Light microscopes can be over six feet tall. It is difficult to enhance the contrast between cells and their surroundings to see cell structure and movement with a light microscope.
Answer: Cytosol; Mitochondria
Explanation:
Anaerobic reactions occurs in the ABSENCE OF OXYGEN ONLY, and involves the breakdown of sugar molecules into lactate and occurs in the CYTOSOL of activel skeletal muscles during movement
In contrast, aerobic reactions of respiration are reactions that occurs in the presence of oxygen ONLY, and involves the breakdown of sugar molecules into carbon dioxide, water and energy (in form of ATP). It occurs within the inner membrane of the mitochondria.
Answer:
D) Silent mutation on second codon, third amino acid changed from ILE to ASN.
Explanation:
Silent mutations are usually point mutation where you change one nucleotide. Since, the nucleotide changed is the third position, it does not affect the protein being manufactured (it will still put the amino acid Ala) [look up the codon redundancy on youtub.e to understand how awesome nature is!]
On the other hand, the other mutation introduced is Missense mutation where a different Amino acid is added due to change in codon (goes from ILE to ASN).
Answer:
they are not living because when they fell from the tree they stopped getting water. so it depends on how long ago they fell.
Answer:
The correct answer is - 1.57 × 10⁶ codons.
Explanation:
Given:
No. of base pairs in E.coli DNA = 4.70 × 10⁶
we know :
1 codon = 3 DNA nucleotides
Solution:
No. of of base pairs in DNA = No. of nucleotides in a single strand
= 4.70 × 10⁶
It must have 1/3 this number of triplet codons
= 4.70 × 10⁶ / 3
= 1.57 × 10⁶ codons.
Thus, the correct answer is - 1.57 × 10⁶ codons.
