Sympathetic Nervous System -> Raises Heart Rate
Peripheral Nervous System -> Runs throughout the body
Central Nervous System -> Brain and Spinal Cord
Autonomic Nervous System -> Digestion and emotion
Somatic Nervous System -> Sensation and body movement
Answer:
The answers are explained below:
- Black rough fur - .
- Black smooth fur - .
- White rough fur - .
- white smooth fur -
Explanation:
- The genotype of homozygous black fur and smooth texture: BBrr.
- The gametes produced are : Br
- The genotype of white and heterozygous for rough texture: bbRr
- The gametes produced are : bR and br.
- The cross,
bR br
Br BbRr Bbrr
(B/R) (B/S)
- B - Black.
- R - Rough.
- S -Smooth.
- The cross can develop two types of offspring, that is,
- Black and Rough (BbRr) - 1.
- Black and smooth (Bbrr)- 1.
- Black rough fur - .
- Black smooth fur - .
- White rough fur - .
- white smooth fur -
When the rate of repair lags behind the rate of mutation, the possible fate of the cell is that (A) The cell can be transformed into a cancerous cell.
Mutations are the changes in the sequence of genes. If the rate of repair lags behind, there is a major possibility that the cell can turn into a cancerous one. This is because mutations are a big reason for the appearance of cancer.
A cancerous cell is the one that proliferates at an excessive rate. The most important property of cancerous cell is of metastasis. It is the movement of the tumor into different parts of the body and infect the healthy cells of that area as well.

A lipid molecule primarily is used as a storage mechanism for the cell as ATP doesn't last very long before degenerating.
Answer:
The correct answer is : A.
Explanation:
- This is because of the following reasons:
- Escherichia coli is a bacteria and hence is a prokaryote.
- The cloning of human (eukaryote) genes is done to obtain in-vitro protein expression which are to be used a pharmaceutical compounds.
- Although the phenomenon of Central Dogma takes place in both Prokaryotes and Eukaryotes, the mechanism is very different.
- Some of the differences includes:
- Eukaryotic genes contain certain non-protein encoding sequences called the Intron sequences which needs to be removed from the transcribed mature mRNA by Spliceosome. This phenomenon is absent in prokaryotes as they do not possess introns. Hence, proper processing of eukaryotic mRNA is not possible in prokaryotes.
- The mature eukaryotic mRNA has a 5' cap and 3' polyadenylated tail which is added by a capping enzyme and a poly-A polymerase enzyme to increase their stability. This will not be possible in a prokaryote as they lack these enzymes.
- The translation of membrane proteins and secretory proteins is carried on by the ribosomes bound to the endoplasmic reticulum. This structure is absent in prokaryotes, hence they will be unable to produce a proper polypeptide sequence.
- Finally, the eukaryotic proteins undergo various modifications after formation, like methylation, acetylation, etc. These reactions cannot be carried out in a prokaryote as they lack the respective enzymes.
- Hence, we see a properly folded functional eukaryotic protein cannot be produced in a prokaryote.
