Answer: Mitochondria will be numerous in the heart muscle.
Explanation:
The heart muscle is the muscle that constitute the walls and tissue of the heart. It help to keep the heart pumping during involuntary movement. The heart muscle work hard and costumes alot of energy. The heart muscle have numerous of Mitochondria. Mitochondria is numerous in cells where there is high need of energy.
The Mitochondria is a membrane bound organelles that generate energy which is use by the cells for biological processes. Mitochondria help to generate energy.
Answer: B
Explanation:
The T helper cell needs to acttivate the T cyctotoxic cell in order for the Tc cell to go do its work.
Once the TC cell is active it interacts with MHC-1 proteins on the surface of the infected host cell, this allows the Tc cell to recignise the host cell and begin secreting cytotoxins (perforins and granzymes) in order to degrade the infected cell and cause apoptosis (controlled cell death)
Cyclins
are the chemicals that regulate the cell cycle. Cyclins work by regulating the timing
of the cell cycle in eukaryotic cell. Cyclins activates cyclin dependent
kinases (CDKs) (an enzyme that works by adding <span>negatively charged phosphate groups to other
molecules in a process called phosphorylation) by binding to it to form a cyclin-Cdk
complex. This complex then functions by acting as a signal to the cell to move
to the next cell cycle phase. At the end of the event, the cyclin is degraded, Cdk
is deactivated, therefore signaling exit from a specific phase.</span>
