Microscopes have been used for centuries in order to see specimen scientists cannot see with their unaided eye. Antón VanLeeonhoeuk is given credit for designing the first lenses for microscopes in the 16th century. He looked at “animacules” which we would now call bacteria and protists. Robert Hooke first coined the term cell, as he looked at cork and thought it looked like cells that monks slept in. Improvements were made in the following centuries, and Ernest Leintz in the 1800s creates a way to have differing magnification lenses on one microscope. Continuing into the 1900s and 2000s there are now electron scanning microscopes, ultraviolet microscopes, atomic force microscopes, and electron tunneling microscopes—all which allow scientists to have better resolution and to see smaller and smaller things. Microscope technology will continue to improve as scientists discover more ways to magnify the microscopic world.
Answer:
The energy used for muscular cont ration is ATP(adenosine triphosphate) This is the energy currency produced in the mitochondrial during cellular respiration.
During muscles contraction.The ATPs is broken down to ADP and Pi.
This is the breakdown of energy rich bonds binding phosphate ions with ATP.The breakdown of the bonds produced -32kJper the 3 bonds in ATP. Therefore as each bond is broken, energy is produced for muscle contraction
It is an exergonic reaction with production of heat.
Thus ATP is used for muscle contraction.ADP is the intermediate of ATP when one Phosphate is removed during the breakdown.
Thus the sequence is Adenosine triphosphate (3 phosphate) to Adenosine diphosphate(2 phosphate) to Adenosine monophosphate (1 phosphate)
Each bond breakin gives equal energy of -32kJpermol.

Explanation:
An increase in a predator population will directly result in THE DECREASE IN THE PREY POPULATION.
Predation is a biological interaction where one organism feed over another organism and the other organism is harmed. The organism benefited is called predator while the one harmed is called prey. Predator is generally bigger in size than the prey. If the population of predator is increasing it will lead to the decrease in the population of prey as more predators will feed on the prey.
Answer:
Plant and animal cells have a plasma membrane, a nucleus, mitochondria, ribosomes, endoplasmic reticulum, Golgi apparatus, peroxides, and micro-tubules.
Explanation:
Both animal and plant groups have few alike structural elements. Leading off, they are both eukaryotic, which indicates they have a specified nucleus. The nucleus comprises chromosomes. It is guarded and enclosed by the cytoplasm, which is a wet or gel-like liquid. Animal and plant cells own a cell membrane that encloses the cell.
