Are atoms created or destroyed in a chemical reaction? How do you know?​

Biology
1 answer:
marusya05 [52]3 years ago
6 0

Answer:

No atoms are created or destroyed in chemical reactions.

Explanation:

Matter cannot be created or destroyed. When two reactants contact each other, a chemical reaction occurs which breaks the bonds between atoms and rearranges them, forming new bonds which transform them into the product. The same amount of atoms exists before and after the reaction.

Softa [21]

Plate tectonic induced changes in the sea level could increase the total percentage of land area upto 40% or decrease it to as low as 17%

<h3>What are Tectonic plates?</h3>

Plate tectonics, whose name derives from the Late Latin tectonicus and the Ancient Greek letter v, which means "pertaining to building," According to the widely accepted scientific idea , the Earth's lithosphere is made up of many major tectonic plates that have been gently shifting for nearly 3.4 billion years

The model is based on the idea of continental drift, which was created in the early 20th century. After seafloor spreading was confirmed in the mid- to late 1960s, plate tectonics became largely accepted by geoscientists.

1.<br> Describe two advantages of genetic engineering.
Novay_Z [31]
One advantage of genetic engineering is the production of valuable proteins: recombinant DNA made possible the use of bacteria to produce proteins of medical importance such as genetically engineered human insulin which is of great importance.
Another advantage is the production of vaccines. Vaccines produced by genetic engineering offer an advantage that the microbial strains from which proteins are extracted do not contain complete viruses and thus there is no risk of accidental inoculation with live virus.
