Cells need mitosis in order to keep the supply of cells suitable for the human body to continue circulating with
Answer:
The correct answer is - through facilitated diffusion and active transport.
Explanation:
Glucose is a six-carbon sugar molecule that is directly utilized by cells to provide energy. A glucose molecule is large enough to go through a cell membrane with simple diffusion.
Cells help glucose molecules to cross the cell membrane through facilitated diffusion and active transport. Active transport is of two types primary and secondary active transport to help the glucose molecule to cross the membrane.
Thus, the correct answer is - through facilitated diffusion and active transport.
Given that an average human has a heart rate of 70 beats per minute and if one is to have a 70 year life span, the number of times it will beat is 2,575,440,000 times. This was computed by multiply 70 years by 365 days/year x 24 hours/day x 60 minutes/hour x 70 beats/min. Thus, the heart will beat numerous times before it finally stops.
Answer:
b. pieces of DNA is the correct answer.
Explanation:
A gene is a piece of DNA and it is present in the nucleus of all cell's
The function of the gene is to codes for a specific type of protein.
Genes convey the message that determines our characteristics
Genes are called as a functional unit of genetics.
Answer:
Valinomycin is an antibiotic that are mainly used against the bacteria streptomycin. The valinomycin might also acts as the ionophore used for the regulation of the ions transport.
Only some selected particles can pass down to the plasma membrane. The hydrophobic molecule can easily cross the plasma membrane. Valinomycin is hydrophobic on its exterior surface and easily diffuse through the cell membrane. Valinomycin is hydrophillic from the interior surface and used for the encapsulation of the polar ions.
