Heat convection is a mode of heat transfer by the mass motion of a fluid such as air. Heat convection occurs to the surface of an object where the surrounding fluid of object is heated and moved energy away from the source of heat.

AKA. RADIOMETRIC DATING
We can learn about the past by studying the present.
The Principle of Uniformitarianism states that current geological processes are the same processes that were at work in the past. This principle was proposed by Charles Lyell in the 1800's
Absolute Dating
Involves finding the absolute age (actual age) of a rock or fossil.
Elements that emit particles and energy are radioactive.
As radioactive elements emit particles and energy, they form new isotopes or elements.
Starch is a polymer composed of glucose units as monomers. Hydrolysis reaction can break down large molecules into smaller ones.
- Hydrolysis is a type of chemical reaction in which a water (H2O) molecule is used to break down large molecules into smaller ones.
- Starch is a complex polysaccharide composed of more than six (6) glucose molecules linked by alpha-glycosidic bonds.
- Glycosidic bonds can be hydrolyzed by specific enzymes known as glycosidases.
- A starch molecule composed of 300 glucose molecules contains 299 alpha-glycosidic bonds.
- In consequence, in this case, 299 water (H2O) molecules are required to completely hydrolyze the amylose starch polymer into glucose monomers.

Answer:
The right answer is Compound light microscope
Robert Hooke is one of the first scientists to build and use a compound microscope, a multiple lens assembly, usually three in number: an eyepiece, a field lens, and a lens. He gives many tips for the manufacture of microscopes manufacturer Christopher C-o-c-k. But this attribution seems inaccurate, because Zacharias Janssen had already built similar microscopes in 1590. Nevertheless, the Hooke microscopes reached a magnification of 30 times, which was much superior to the previous instruments
Explanation:
Gene therapy is a promising possibility for the treatment of these diseases. With the help of genetically modified viruses, DNA is introduced into cells in order to repair or replace defective genes. By using this method, scientists have discovered a quicker and more efficient treatment for the cells. Hope this helps :)
