Answer: True
Explanation:
DNA is a biological evidence. It is a heredity material which is present in all organisms on earth. The DNA in humans can be taken as sample from nails, bones, blood, skin, hair and other sources.
The DNA samples can be taken so as to establish the identity of the culprit, victim or any one which is associated with crime.
The DNA evidence has applicability as a potent evidence in the court of law. Thus utmost care should be taken to preserve it's integrity until it is analysed and presented in the court of law.
Thus the DNA evidence should be collected and preserved in airtight containers so as to prevent the entry of airborne pathogens like bacteria, virus these can contaminate the sample evidence and can make the evidence not of any use.
Answer:
A Recessive
Explanation:
Generally, there are two types of disorders, progressive and recessive. When something is recessive, it is not a dominant gene. The reason why sickle cell anemia is classified as a recessive disorder is because it only affects some people, but it does not affect all those who share DNA. Hope this helps!
<u>The resting </u><u>membrane</u><u> potential would become </u><u>more positive</u><u> because researchers are taking negatively charged molecules out of the cell.</u>
Which methods were used to record the resting membrane potential and action potential of the squid axon choose all that apply ?
- The squid axon's action potential and resting membrane potential were captured using the following experimental strategy.
- Using a recording microelectrode inside the cell that is connected to a second electrode outside the cell .
What is cell membrane ?
- All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment.
A semipermeable lipid bilayer makes up the cell membrane. - The movement of materials into and out of the cell is controlled by the cell membrane.
What are the functions of a cell membrane?
- The cell membrane, therefore, has two functions: first, to be a barrier keeping the constituents of the cell in and unwanted substances out .
- second, to be a gate allowing transport into the cell of essential nutrients and movement from the cell of waste products.
