Fast-glycolytic muscle fibers are another name for Type IIb skeletal muscle fibers and are white in color. The skeletal muscle fibers are divided into three types: Slow-contracting muscle fiber (Type I), Fast-contracting muscle fiber (Type IIa) and Fast-contracting muscle fiber (Type IIb).
Fast-glycolytic muscle fibers Type IIb are abundant in muscles of the lower limbs that contract quickly and are oxygen dependent, prevalant in postural muscle of the back, generate lots of power and depend on lots of power and depend on anaerobic pathways to make ATP , have fewer but larger myofilaments and numerous mitochondria, have abundant myoglobin.
Answer:
The correct answer is option C.
Explanation:
As it is given that, a Mendelian cross is performed between two parents resulted by cross the parents. This suggests that the parents or P generation has zero recombination hence the genotype of Parents would be AA and aa in nature. Therefore, all the F1 generation offspring were Aa in nature. The selfing of the F1 offspring will be:
A a
A AA Aa
a Aa aa
Genotype: AA: Aa: aa :: 1:2:1
Phenotype: Dominant: recessive :: 3:1
Because fungi dont live off of sunlight the are under the class of decomposes which means that they grow off of dead things getting nutrients from that
Answer:
Lichens that colonize bare rock secrete acids that break down the rock and start the soil-production process. Also, as lichens die, they provide some organic matter that also contributes to soil. Mosses can then colonize the thin soil; as mosses die, the soil thickens more allowing other hardy species to colonize
Explanation:
Answer:
Control of both RNA splicing and chromatin remodeling control of RNA splicing.
Explanation:
RNA is present as genetic material but in case of some viruses only. RNA contains the nitrogenous base ( adenine, guanine, uracil and cytosine), oxyribose sugar and phosphate group.
The bacteria do not have well developed nucleus so no chromatin remodification occurs in case of bacteria. Bacteria is devoid of introns and contains only exons in its RNA structure. The splicing process is not required in case of bacteria.
Thus, the correct answer is option (4).
