Heres the answer to that..<span>concentration gradient</span>
Hello there.
<span>The crossing over is a process where the chromatids pair and exchange sections of DNA, which lead to exchange genes (this result is call genetic recombination). So, the crossing over between nonsister chromatids during meiosis is significant in heredity because it leads to an increase of genetic variation (answer d.)</span>
Answer:
C . Lymphoid tissue is predominantly reticular connective tissue
Explanation:
Answer:
Tropomysin, calcium
Explanation:
Tropomysin is a protein that prevents muscle contraction hence acts as a contraction inhibitor. It wraps around the actin blocking the binding sites for myosin on the actin.
Muscle will only contract when they get a rush of calcium ions.
The calcium ions binds to troponin, the troponin changes its shape. The change in shape will remove tropomyosin from the binding sites allowing myosin to bind on the actin leading to muscle contraction.
Answer:
D) A bacteriophage that has been modified to carry the gene.
Explanation:
To achieve her goal, she should use (d) A bacteriophage that has been modified to carry the gene. Bacteriophage are diverse group of viruses which are easily manipulated.
