Answer:
Technological advances in farming and medicine will allow human populations to continue to grow without natural limits.
Explanation:
1 prokaryotic- a cell that lacks a nucleus and membrane-bound organel
2 eukaryotic-a cell that has a nucleus
3. Cell theory the theory that states that the cell is the basic unit of life and that cells come only from existing cells
4 cell - the basic unit of life
The best answer is the third option namely an enclosed nucleus.
One major difference between these two types of cells is that a prokaryote cell has no distinct nucleus enclosed with a membrane whereas in a eukaryote cell the genetic material, which is DNA, is packaged into chromosomes and found within a distinct nucleus that is enclosed with a membrane
Examples of prokaryotes are bacteria such as staphylococcus species found as commensals on the skin of man and Streptomyces soil bacteria from which the antibiotic streptomycin is derived.
Examples of eukaryotes are an amoeba, which is a unicellular protozoan that lives in water and a hepatocyte which is a liver cell in man.
Answer:
a. is converted to NAD+ by an enzyme called dehydrogenase
Explanation:
The electron transport chain of cellular respiration is the final step that oxidized NADH and FADH2. These reducing powers are formed during glycolysis and Kreb's cycle. Complex I of the electron transport chain present in the inner mitochondria membrane is NADH dehydrogenase. This protein complex accepts electrons from NADH and oxidizes it into NAD+. NADH dehydrogenase couples oxidation of NADH with the pumping of proton towards the intermembrane space.
Answer:
Force, F = 90 N
Explanation:
Given that,
Mass of the bicycle and rider, m = 60 kg
Acceleration of the bicycle and rider, a = 1.5 m/s²
We need to find the force acting on the bicycle and rider to accelerate. Let it is F. Its force is given by :
F = ma
F = 60 kg × 1.5 m/s²
F = 90 N
So, the force acting on the bicycle and rider is 90 N.
