Answer: d. in the body can operate at a mechanical advantage or mechanical disadvantage, depending on specific location.
Explanation:
A first-class lever is defined as the force in which fulcrum is present in the center and the load and effort on each side of the fulcrum. First class lever moves over a large distance to move the load to a smaller distance.
First-class lever can be operated at mechanical advantage or disadvantage that it can aid in work by changing the direction of the force and by increasing the efficiency. As the the fulcrum is between the load and the effort so the length of the effort arm divided by the length of the effort arm.
If the fulcrum is closer to the effort, it will operated at mechanical disadvantage and vice versa.
Example of first class levers includes scissors, a claw hammer, a see-saw and a weighing balance.
Hence, the correct option is D.
b. transmission electron microscope
c. scanning electron microscope
d. compound light microscope
Answer:
The correct answer is option b.
Explanation:
Transmission electron microscope or TEM emits electrons that pass through the vacuum tube of the microscope. TEM has an electromagnetic lens that focuses the electrons into a very fine beam.
The transmission electron microscope can be used to seeing very thin specimens of tissue sections, molecules, and other smaller structures that can not be seen by light microscope or dissecting microscope, in which electrons can travel creating a projection image.
Thus, the correct answer is option b.

glycolysis :) I hope this helped
Pyruvate is produced in the glycolysis stage of cellular respiration, where a glucose molecule is split into two pyruvate molecules. This process occurs in the cell's cytoplasm.
The stage of cellular respiration that produces pyruvate as a product is glycolysis. Cellular respiration is a series of metabolic processes by which living cells produce energy through the oxidation of organic substances. The glycolysis pathway is a 10-step biochemical pathway where a glucose molecule is split into two pyruvate molecules. This process occurs in the cell's cytoplasm. Electron transport chain, Krebs cycle and fermentation are all stages of cellular respiration, but they do not produce pyruvate.

Answer:
The organism's parents have to either be heterogeneous dominant or homogeneous.
Explanation:
When the traits get passed down they either have to have 2 dominant traits or a mix.
