Answer:

4 chromosomes

Explanation:

Meiosis is a kind of cell division that produces daughter cells that already have their chromosome number reduced by half. Due to this reason, meiosis is called a reduction division. A diploid parent cell (2n) will produce gametes with haploid cells (n).

According to this question, a fruit fly has 8 chromosomes or 4 pairs of chromosomes in its wing cells, after undergoing meiotic division, it will possess 4 chromosomes in each gamete cell. Note that the chromosome number has been reduced by half.

The label on a bag of salt-free pretzels indicates that they chips are "low-fat." this means the pretzels provide _____ gram(s)

The label on a bag of salt-free pretzels indicates that their chips are "low-fat." this means the pretzels provide 3 gram(s) of fat or less per serving.

Low-fat diets are diets in which the fats are reduced. Low-fat diets are produced in order to prevent diseases such as obesity and heart diseases. Food manufacturers usually use nutrient claims such as '‘low fat’' to indicate the nutritional value of their products. A ‘low fat’ food contains not more than 3g of fat per 100g of food  (for solids) and not more than 1.5g fat per 100g (for liquids).

Gene expression in eukaryotes can be regulated at many different levels. List the different levels of regulation, and explain wh
Aneli [31]

Answer:

Transcription, mRNA (processing, transport, localization and stability), translation.

Explanation:

  • Transcription is regulated in two levels, though chromatin regulation (methylation and acetylation) to loose or increase histone's affinity to DNA and through cis and trans elements such as promoters, enhancers, and silencers (cis) to active/deactivate and RNA polymerase and transcription factors and co-factors (trans).
  • mRNA can be regulated using poly-A tails or 5'-caps to shorten or give them more time before they degrade, it could also be spliced to eliminate introns.
  • In the translation stage, the regulation occurs during the initiation through a scanning procedure that ensures the 40s ribosomal subunit bind correctly to the untranslated portion of RNA

Hope this information is useful to you!
