Answer:

Option (a).

Explanation:

Viruses display the characteristics of the living as well as non-living organism. The virus has the ability to reproduce but inside the host cells only.

Viruses has DNA or RNA as their genetic material. Most of the viruses are smaller than bacteria as the virus can easily pass through the bacteria filters. The size of virus is almost smaller than the bacteria. Virus has the ability ti infect the bacteria also.

Thus, the correct answer is option (a)

Explain how the use of genetically engineered products can affect the economy and society.
ZanzabumX [31]

Answer:

due to gmos we can expand the shelf life of many of our foods and prevent them from the harm of pests. You night be rhinking why not use pesticides? well, we did but eventually the pests became immune to the low dose of pesticide. over time we gradually increased our uses of pesticides. more commonly round up. this pesticide specifically was known for being a carcinogen. (something that causes cancer.) Genetically modifying a crop can severely decrease the amount of pesticides used for our crops and could also potentially drop the prices. for example, in hawaii during the 1940s to 1990s the ringspot viruses hit the hawaiian papaya harvest hard. this reduced the amount of papaya produced by 50 percent by 1993 and 2006. the ringspot virus nearly wiped out the entire crop. within 11 months, the hawaiian papya was saved. due to gmos of course. this is because scientists took genes from immune papayas which very rarelt occured (at the time) and injected it into many other papya plants. as the plants grew, new papaya was produced which was immine to ringspit virus. PAPAYA WAS SAVED!!!!

I hope this helped! :) Have a nice day!

While studying the function of a G protein-coupled receptor you develop a modified GTP molecule that has the same binding capabi
laila [671]

<u>Answer:</u>

Effects Include:

Activates secondary messengers such as cAMP which further activates number of hormones like

  • ADH: production of this hormone causes kidneys to retain more water inside body.
  • GHRH: release growth factors and stimulates growth of organism.
  • ACTH: produces fight or flight responses i.e rise in heart beat, rise in Blood pressure etc
  • TSH: Stimulate the synthesis of Thyroid hormone and enhances the metabolism of body. In rare cases causes Goiter without the deficiency of Iodine.
  • LH: Stimulate follicle maturation and formation of ovules in women.
  • Calcitonin: Decreases blood calcium level by deposition calcium in bones. This effect weakens the muscles.
  • Glucagon: Stimulates glycogen breakdown from liver and muscles and many more effects.

<u>Explanation:</u>

Background Knowledge:

GPCR (G Protien coupled receptors) are present inside plasma membrane in huge amount. As name suggest that these receptors are coupled with G proteins during their inactive state present inside of the cell. During their Inactive state these G proteins are bounded with GDP molecule.

Upon receiving signal molecules from outside of cell alters the shape of GPCR. These receptors also triggers change in G Protein, as a result of this GTP get attached with them. This protein further activates reaction cascades inside of the cell.

What happen if GTP cannot be hydrolyzed to GDP + Pi?

If GTP cannot hydrolyzed in to GDP + Pi than, it cannot be able to dissociate from G proteins. Cascade system doesn't stop and produces many effects on body.

Effects Include:

Activates secondary messengers such as cAMP which further activates number of hormones like

  • ADH: production of this hormone causes kidneys to retain more water inside body.
  • GHRH: release growth factors and stimulates growth of organism.
  • ACTH: produces fight or flight responses i.e rise in heart beat, rise in Blood pressure etc
