Answer:
There aren't any blood vessels in the epidermis; they're located right below it in the dermis, the middle layer of our skin. If you cut yourself and bleed, it means you've torn through the epidermis and left the dermis exposed.
Explanation:
Answer:
b) It provides genetic variation in organisms due to crossing over
c) It provides a reduced number of chromosomes in gametes
Explanation:
These are the factors as to why meiosis is important.
Answer:
Yes
Explanation:
A primer is a short, single-stranded DNA sequence used in the polymerase chain reaction (PCR) technique. In the PCR method, a pair of primers is used to hybridize with the sample DNA and define the region of the DNA that will be amplified. Primers are also referred to as oligonucleotides.
Answer:
The electric field on the surface of a conductor is perpendicular to its surface.
Explanation:
A conductor is a material that has the ability to transport electric charge through it.
Inside such a conductor that is in equilibrium, the electric field is zero, so that the charge accumulates on the surface of the conductor.
The electric field on the surface of a conductor is perpendicular to its surface.
This external electric field on the surface of the condutor can be calculated by Gauss's law, which establishes the equivalence of the flow across a surface with the net charge inside the conductor divided by the permittivity in the vacuum.
