It is found in the thylakoid membrane
Answer:
A) increasing frequency of action potentials only.
Explanation:
If the muscle fibers begin the contraction with the sarcomere too elongated, the thick and thin filaments would be barely overlapping, forming few crossed bridges. On the contrary, if the sarcomere is too shortened so that the thick filaments reach the z-disks, the myosin is unable to find new fixation sites for cross-bridge formation and the tension decreases rapidly.
But to better understand how the contraction force increases, it should be noted that a single contraction does not represent the maximum force that a muscle fiber can develop. <u>The force generated by the contraction of a muscle fiber is increased, increasing the frequency with which the action potentials of the muscle stimulate said fiber,</u> that is to say that the nervous system controls part of this.
A potential muscular type action lasts between 1 and 3 ms. While muscle contraction can last 100 ms. If the repeated action potentials are separated by prolonged intervals of time, the muscle fiber has time to fully relax between the stimuli. If the action potentials continue to stimulate muscle fiber repeatedly at short intervals (high frequency), the relaxation between contractions decreases until the muscle fiber achieves a state of maximum contraction known as tetanus.
I think it is C as plants take in Co2 and release oxygen which humans use to breathe.

Answer:
This question lacks options, the options are;
A. Genes are made up of chromosomes and both are found in the cell’s cytoplasm.
B. Chromosomes are made up of genes and both are found in the cell’s cytoplasm.
C. Genes are made up of chromosomes and both are found in the cell’s nucleus.
D. Chromosomes are made up of genes and both are found in the cell’s nucleus.
The correct answer is D.
Explanation:
As rightly stated in this question, every living organism requires a set of instructions that specifies its traits. These set of instructions are embedded in a unit called GENE. Genes hold information needed for the survival of a cell in an organism.
These genes are located on a structure called DNA, which are folded or packaged into another structure called CHROMOSOMES. Each chromosome, hence, contains genes that are the unit of inheritance of a cell. In eukaryotic organisms, the gene is found on a chromosome, which is located in the NUCLEUS of the cell.
