The brain which, along with the spinal cord gathers informationand responds to changes in the environment.
Explanation: Saturated fatty acids have single carbon-to-carbon bonds. Therefore, saturated fatty acids have straight structures while unsaturated fatty acids have bent structures. Saturated fatty acids are solid at room temperature and unsaturated fatty acids are liquid at room temperature.
I. treating the substance with nucleases that destroy all nucleic acids and then determining whether it is still infectious
Explanation:
Analysis of the nature of the specimen like the infectious agents (bacterium, virus, viriod, or prion) is very important to diagnose the diseases caused by them, investigate disease outbreak, to determine the clinical course of the infectious disease etc.
There are many methods like direct detection, cultivation assays, serological assays to detect the pathogen type.
Molecular techniques like polymerase chain reaction (PCR) is done to further analyze or investigate the pathogen, like its microbial genome, the virulence factor etc. These are amplification methods which help to investigate the pathogenesis and disease progression. PCR method involves denaturing the DNA polymerase which is a nuclease type of enzyme. Nucleases are present with exonucleases and endonucleases, both of which acts at specific points on the DNA of the pathogen and will create new templates .
Answer:
The options
A. Comma splice
B. Fused sentence
The CORRECT ANSWER IS A.
A. Comma splice
Explanation:
In English grammar, a comma splice can also be called a comma fault.
It occurs when the comma is uesd to join two independent clauses or complete sentences with a comma and no conjunction.
This form of writing is often used in literary writing to portrait a certain mood of informality.
A comma splices can be corrected in three varying ways such as:
-using a coordinating conjunction (for, and, nor, but, or, yet, so) to come right after the comma.
-converting the comma to semicolon.
-converting the comma to a period
Answer:
1. 8 copies of each gene in somatic cells
2. 4 copies of each gene in gametes
Explanation:
According to the question, strawberry is an octoploid organism (8n). This means that it contains 8 sets of chromosomes in its genome. If it contains 8 copies of each chromosome, then it also contains 8 copies of each gene in its body or somatic cell (4 copies from each parent).
However, it will produce gametes or reproductive cells via meiosis. Meiosis is a kind of cell division that reduces the chromosomal number by half. Hence, an octoploid strawberry (8n) with 8 copies of genes will undergo meiosis to produce gametes that have 4 copies of each chromosome and hence, four copies of each gene i.e. 4n (tetraploid).
