The answer to the above question, is C. the main two sources are wind and sun (wind turbine and solar panels).
The macromolecule must be starch.
Explanation:
Starch is a polymer of Glucose joined by glycosydic bond.
Starch is the main energy storage substance in green plants.
Starches react with iodine and give a bluish black or black color and thus iodine test is considered as a confirmatory test for starches.
In this experiment ,the solution turns very dark black on addition of iodine so we can be sure that the solution contained starch.
Answer and Explanation:
When mRNA leaves the nucleus and meets a free ribosome in the cytosol, it starts the protein building. Ribosomes read the mRNA code and begin protein synthesis by adding the correct amino acid using transference RNA.
Ribosomes attached to the RER membrane are responsible for synthesizing membrane proteins, exportation proteins, or enzymes.
The synthesis of proteins destined to become enzymes, membrane proteins, or exportation proteins starts in the cytoplasm with the production of a molecule portion known as a signal aminoacidic sequence. This signal sequence in the amino extreme of the synthesizing protein, and when it reaches a certain length, it meets the signal recognizing particle that leads the synthesizing protein and associated ribosome to the Rough endoplasmic reticulum, where it continues the protein building until finishing the elongation process. When the new protein synthesis is complete, the polypeptide is released into the reticulum lumen, suffering a few posterior steps related to conformation and structure, such as folding to become functional and the initial glycosylation stages.
The new proteins get packaged into vesicles that carry them to the Golgi complex where occurs the final association of carbohydrates and lipids with proteins, to originate glycoproteins and glycolipids.
Enzymes destined for exportation are packaged and sent from the Golgi complex to the cell membrane into vesicles. When the secretory vesicle reaches the target, its membrane fuses with the cell membrane, releasing its content to the extracellular space. This secreting process is known as exocytosis.
The formula that forms acetic acid is CH3COOH
Answer:
Founder effect
Explanation:
Genetic drift is the process of change in allele frequency in a population because of chance increase or decrease in number of particular alleles in that population. It can be caused due to may reasons like founder effect, bottleneck effect etc.
Founder effect is a phenomena where a small group of individuals migrate from the original population to some other area and start a new population. The new population will all result from this small founder population. So if by chance some alleles were present more in the founder population, the new population will also show high frequency for it. As a result the allele frequencies in the new population can differ from the original first population.
Here, the Amish population in North America was settled by a small number of immigrants from Europe. Among those immigrants many had alleles for genetic dwarfism. So when this small population grew in America, genetic dwarfism also became prevalent in them.
