Answer: e. prokaryotic cells lack nuclei.
Explanation: Prokaryotes are unicellular (single-cell) organisms that lack well developed cell internal membrane-bound structures or organelles. They do not have a nucleus but generally, they have a single chromosome that possess a double-stranded DNA located in an area of the cell called the nucleoid. Most prokaryotes have a cell wall outside the plasma membrane.
Answer:
Explanation:
Deoxyribonucleic acid (DNA) is hereditary molecule found almost in every cell. Although it is very stable molecule but changes known as mutations may occur in this molecules. Deamination is also a type of mutation.
Deamination:
In deamination amino group is removed from Cytosine and produces uracil in DNA. This rate of conversion occurs about 100 bases per cell per day.
Sequence given in question is
... TACT... .
....ATGA...
After deamination the given sequence becomes
... TAUT... .
....ATAA...
Technically, the definition is that autotrophs obtain carbon from inorganic sources like carbon dioxide (CO2) while heterotrophs get their reduced carbon from other organisms. Autotrophs are usually plants; they are also called "self feeders" or "primary producers".
Convergent A subduction zone is formed at a convergent plate boundary when one or both of the tectonic plates is composed of oceanic crust. The denser plate, made of oceanic crust, is subducted underneath the less dense plate, which can be either continental or oceanic crust.
Answer:
Explanation:
A. Static equilibrium monitors head position when the body is not moving
G. An example of static equilibrium occurs when a person is asleep.
H. An example of dynamic equilibrium occurs when shaking one's head "no."
B. Dynamic equilibrium monitors angular or rotational movements of the head when the body is moving.
