Answer:

Agriculture  

Explanation:

Genetic engineering can be defined as the use of genetic techniques aimed at modifying the genome of living organisms, thereby being used to develop Genetically Modified Organisms (GMOs). In the USA, genetic engineering methodologies have been used in agriculture to improve crop yields and reduce costs (for example, by reducing the need to use pesticides). Some of the most important genetic engineering techniques that nowadays are being used in agriculture research include biolistic transformation, <em>Agrobacterium</em>-mediated transformation, the CRISPR-Cas9 genome editing system, etc.

In a cell with defective chaperones, Question 14 options: proteins would not be able to exit the ribosome. the concentration of
BartSMP [9]

Answer:

the concentration of misfolded proteins would be higher than normal.  

Explanation:

Chaperones proteins are required for the correct protein folding of proteins. These proteins were first discovered in bacteria. The level of chaperones is increased under thermic stress conditions, it is for that reason that they are also known as heat shock proteins (Hsp). For example, Hsp70 is a chaperon protein constitutively expressed under stress conditions that is involved in the folding of protein precursors and the refolding of misfolded proteins. In humans, Hsp70 is encoded by the HSPA1A gene, and its increased expression level is related to different health problems including neurodegenerative diseases, cerebral ischemia and epilepsy.

PIT_PIT [208]

Answer:

Do you mean planets?

if so,The heavy rocky particles within the inner part of the disk formed planetesimals and eventually, inner planets. In our solar system, the four innermost planets Mercury, Venus, Earth and Mars are known as inner planets. They lie inside the asteroid belt. They have volcanoes and valleys and are very hot compared to outer planets.Inner planets are much smaller than the outer planets, and are rocky with an iron core.

Hope that helps!
