An allergic reaction to certain types of natural, unprocessed foods, such as peanuts, is caused by

siniylev [52]

If you have an allergic reaction, it means your body cannot handle what you give to it. Say flowers (common) make you sneeze and itch, (like my sister) it is because there's something inside whatever makes you allergic is not good for your body, or your body is not used to it. Can I get a thank you and a rating?

*Hope it helps!!*

if a certain tissue of the body needs more energy, which organelle is more likely to abundant in the cells of this tissue? eluci

gregori [183]

<h2>Answer:</h2>

<h3>Chloroplasts</h3>

Chloroplasts and mitochondria are energy-converting organelles in the cytoplasm of eukaryotic cells. Chloroplasts in plant cells perform photosynthesis; the capture and conversion of the energy of sunlight.

All of the following are differences in transcription, RNA processing, and translation between prokaryotes and eukaryotes except

Mazyrski [523]

Answer:

the mRNA goes through extensive modifications such as addition of a poly tail and a 5' cap in eukaryotes but not in prokaryotes.

Differences:

- the promoters in prokaryotes have a -35 and -10 box while in eukaryotes they are variable but have a TATA box from

- the transcription initiation site there is a single RNA polymerase in prokaryotes while eukaryotes have multiple RNA polymerases

- the sigma factor associates with the promoter region in prokaryotes but in eukaryotes there are many basal transcription factors

Explanation:

Ribosomal and transfer RNAs are processed both in prokaryotic and eukaryotic organisms. However, mRNA is only processed in eukaryotes. In eukaryotic cells, mRNA processing involves:

1. Capping at the 5' end. This process has several functions including regulation of nuclear export, prevention of eukaryotic mRNA degradation and promotion of translation.

2. Splicing in order to remove introns and conserve coding exons. Splicing helps to increase the diversity of the eukaryotic mRNAs (and therefore eukaryotic proteins)

3. Polyadenylation by the addition of a poly(A) tail at the 3' end. The poly(A) tail makes the eukaryotic mRNA molecule more stable and also prevents its degradation by exonucleases.

What is the difference between the exchange of gaseous during respiration and photosynthesis.

Harman [31]

Answer:

Photosynthesis doesn't occur at night. When there is no photosynthesis, there is a net release of carbon dioxide and a net uptake of oxygen. ... the rate of photosynthesis is higher than the rate of respiration. there is a net release of oxygen and a net uptake of carbon dioxide.
