Mostly because the 'Kingdom Protista ' is defined by what they are NOT. (e.g. not plants, fungi, or animals). Most are single-celled, some are colonial, and some multicellular. Some are photoautotrophic, some ingestive heterotrophs, and some capable of both modes of nutrition. In other words, there is a lot of diversity between 'protists' - some are closer to animals, and some are closer to plants. Research in molecular biology has helped clear up some of the confusion, but protist classification is an ongoing process.
The correct answer is option D, that is, genetic diversity among the species.
The sum of genetic characteristics in the genetic makeup of a species is known as genetic diversity. It is differentiated from genetic variability that illustrates the capability of genetic features to change.
The genetic diversity functions as a medium for the populations to amend with the fluctuating environments. With more changes, there is more possibility that some individuals in a population will exhibit different forms of alleles, which are appropriate for the surrounding.
These individuals hold high possibilities of survival in order to generate offspring exhibiting that allele. The population will continue for more generations due to the accomplishment of these individuals.
it regulates blood sugar level.
Explanation:
Insulin helps control blood glucose ( sugar) levels by signaling the liver and muscle and fat cells to take in glucose ( sugar) from the blood. Insulin therefore helps cells to take in glucose (sugar) to be used for energy. If the body has sufficient energy, insulin signals the liver to take up glucose ( sugar) and store it as glycogen.
Answer: The answer is Calcium.
Explanation:
Duchenne muscular dystrophy is an X-linked recessive inheritance disorder that is passed from the mother (the carrier) to the child, mostly the male. It is a disorder of progressive muscular weakness. Those who inherit it have a defective gene related to dystrophin which is a muscular protein. The gene that makes Dystrophin is broken and the muscles become weak. Calcium molecules also build up in the muscles.
This causes muscle weakness, frequent falls, trouble running or climbing the stairs and dependency on wheel chairs.
