Answer:
The ENDOPLASMIC RETICULUM serves important functions particularly in synthesis ,folding,modification and transport of proteins . The GOLGI BODY plays key role in sorting many cells proteins and membrane constituents and in directing them to their proper destination. The MITOCHONDRIA produce energy necessary for cells survival and functioning . The RIBOSOMES assumes the role of bringing together amino acids to form proteins.

Answer:
The correct answer would be A). They will all be blue.
Genotype of the parents are BB and bb.
As both are homozygous in nature so, each will produce only one type of gamete.
BB will produce gamete B and bb will produce b as its gamete.
The cross will results in the production of offspring each with genotype Bb.
We know that blue is a dominant trait and thus it will be expressed in heterozygous condition (Bb).
Hence, all offspring would be blue in color.
Diffusion is the passive transport from a high concentration to a low without using energy. homeostasis results from balance.
All of the above

Answer:
The resistance that some bacterial populations develop to an antibiotic is an example of natural selection because the individuals with more resistance are those that survive, being an evidence of evolution since resistance can be inherited to the following generations.
Explanation:
The resistance to antibiotics that bacteria develop is the best example of how natural selection and evolution occurs, especially because of the fast and easy reproduction of these microorganisms.
In the example it can be seen that <u>only the the most resistant bacterial populations to the antibiotic survive over time</u>. Antibiotic resistance is due to mutations developed by bacteria that modify their structure and function so that they are not affected by an antimicrobial. According to natural selection, these mutations make resistance an inherited trait, and future generations will not be sensitive to the effect of the drug.
<u>Why does natural selection occur?</u> Only resistant individuals survive the effect of the antibiotic.
<u>How do you explain evolution?</u> Successive generations of bacteria have evolved, through mutations, to resist the effect of an antibiotic.
