Answer:
D) The virus has entered the genome of the bacterial cell and is in the lysogenic stage.
Explanation:
Virus have two reproductive cycle lytic and lysogenic cycles. In the lytic cycle, the viral genome is expressed using the host molecular machinery and make capsid proteins. These capsid proteins surround the viral genome and make new phages which lyse the host cell and gets released.
After the release, they enter their genome in other host and that genome first incorporates in the host genome and replicates with the host genome. This cycle is called the lysogenic cycle and in this cycle lysis of cell does take place because no new phages are produced in it.
Answer:
C. Document the number of honey-making bees per hive.
Explanation:
Among the given options, the only useful criteria towards the experimental design of honey production are to "document the number of honey-making bees per hive". We know that the increased number of animals would increase the workforce and thus increase the production of honey (direct relation). Therefore, this will give a direct assessment of honey production.
Answer:
According to the genetic code, the amino acids are the following:
- Glycine: encoded by GGC, GGA and GGG codons
-Arginine: encoded by AGA and AGG codons
-Lysine: encoded by AAA and AAG codons
-Glutamic acid: encoded by GAA and GAG codons
Explanation:
The probabilities to observe an amino-acid formed by Glutamic acid in the coding sequence is 2/9 for each codon
Answer:
Latitude on the equator is 0 degrees and longitude is 180 degrees.
If this helps, please give me brainliest.
Answer:
An endospore may survive a drought because it is protected by a THICK WALL
Explanation:
An endospore is a structure that is produced by some bacteria. This structure possesses characteristics such as:
a. Endospores have thick walls
b. They are very resistant and resilient to changes in temperature.
c. They are resistant as well to the action or activity of some chemicals.
d. Endospores serves as a means of protection for microorganisms such as Bacteria.
e. Endospores do not reproduce.
f. Endospores can be dormant or Inactive for a very long period of time.
Endospores may survive drought, activity of chemicals, extreme weather conditions, extreme temperatures due to the presence of thick walls in their structure.
