He must include A. Ribosomes, B. Endoplasmic reticulum and C. Golgi apparatus organelles in the model.
The ribosomes are organelles that are responsible for protein translation and are composed of rRNA and proteins. The rough endoplasmic recticulum synthesizes the protiens and the Golgi apparatus collects and dispatches protein products received from the endoplasmic reticulum. Proteins synthesized in the endoplasmic recticulum are transported into vesicles, which then fuse with the Golgi apparatus and further transported to their destination.
Answer:
The correct option is C. Rare alleles tend to remain rare even when they are dominant.The distribution of a gene among individuals is determined by mating and environmental factors.
Explanation:
Most people believe that a rare allele would only be recessive. But this is not correct. A rare allele can be dominant. The frequency of an allele to occur in a population will depend on the environmental factors. The alleles which code for traits that are best suitable for living in an environment will be seen in more abundance. The frequency of an allele to occur in a population also depends on the breeding trends of the population.
"Rainwater can replace or replenish freshwater sources" and "precipitation, such as rainwater, is a source of freshwater on Earth" statements describe freshwater sources
<u>Explanation:</u>
Rainwater a source of pure distilled water, evaporated by the sun. When it falls it comes in contact of air and land. when ground soaks the water it becomes mineral water. And it is safe for drinking.
All the freshwater sources are result of precipitation from the earth surface,in various form i.e rain,mist,snow. Freshwater falling as rain have materials dissolved from atmosphere in it,sea and the land over which the clouds has travelled.
