Answer:
In the lysogenic cycle, the viral genome gets incorporated into the host genome and replicates with the host genome. In the lysogenic cycle, no proteins and enzymes of the virus are formed while in the lytic cycle protein of viral capsid form and new phages generate in the host cell.
So as the viral genome integrates into the host genome in the lysogenic cycle, therefore, it is difficult for any drug to differentially act on the viral genome. So there are great chances for drugs to target the host genome in the host cell.
But in virus that replicates through lytic cycle drugs can selectively act on viral enzyme and proteins. Therefore it is difficult to make a drug that affects lysogenic virus.
False.
Any time a scientific theory is challenged, it means it's not a good
theory. And this statement is not valid. In theoretical models, they are
revisited when there are further studies and discoveries found in a certain
area where they can be remodeled and reintegrated instead of disregarding its
credibility. Models, theories and paradigms are not challenged but rather
encouraged, they are supported in many studies since these theories and models
were created in order for us to understand a certain phenomenon but it would
likely help the scientific society to be updated in the new forms or spheres of
improvement rather than discouragement.
Answer:
27 genotypes and 8 phenotypes
Explanation:
Supposing that the genotypes of both of the parents are AaBbDd (A, B and D are dominant over a, b and d). After completing the Punnett square, you can predict the following offspring:
I add an image where you can see all the 27 genotypes and frequencies.
Finally, all the 8 phenotypes with the following frequencies:
27/64 A-B-D-
9/64 A-B-dd
9/64 A-bbD-
9/64 aaB-D-
3/64 A-bbdd
3/64 aaB-dd
3/64 aabbD-
<u>1/64 aabbdd </u>
Total 64/64
Note: when a phenotype is A-, it means that it came from either genotype, AA or Aa. The same applies to B- (BB or Bb) and D- (DD or Dd)
Answer: El smog fotoquímico se forma cuando los fotones de la luz solar chocan con moléculas de diferentes tipos de agentes contaminantes en la atmósfera. Los fotones hacen que se produzcan reacciones químicas. Las moléculas de contaminación se convierten en otros productos químicos nocivos, como ya venimos en el laboratorio.
Explanation:
Answer:
Deforestation
Explanation:
people cut down trees to use for paper shelter and heat . when they over do it and clear a large part of the forest its clased deforestation.
