Answer:
Option (A).
Explanation:
Facilitated diffusion may be defined as the process of movement of the particles from the region of higher concentration towards the region of lower concentration with the help of specific integral transmembrane protein.
Facilitated diffusion is a type of passive diffusion and solute particle down the concentration gradient. So this process doesn't require an ATP or any other energy source.
Thus, the mismatched pair is option (A).
Answer:
Some diseases are more common in certain groups of people, such as Caucasians or African Americans because individuals in such ethnic groups often share certain alleles (versions of their genes), that have been passed down to them from common ancestors and a particular genetic disorder may be more frequently seen in such groups if one of these shared genes contains a disease-causing mutation.
Explanation:
Some genetic diseases are frequently seen in certain ethnic groups like Caucasians or African Americans. Individuals in such groups often share certain alleles (versions of their genes), that have been passed down to them from common ancestors and one of these shared genes may contains a disease-causing mutation.
Examples of certain genetic disorders that are more common in particular ethnic groups include the Tay-Sachs disease, which is more common in people of eastern and central Europe (Ashkenazi), Jewish or French Canadian ancestry and the sickle cell disease, which occur among people of African, African American, or Mediterranean heritage.
Some genetic disorders are more common in people whose ancestry can be traced to a particular geographic area. The factors that can lead to development of populations with very different genetic allele frequencies include their geographic origin, selection, patterns of migration, historic events, etc. Certain natural barriers like oceans and other water bodies, high mountains, large deserts, or major cultural factors had prevented communication and interaction between people. So mating was restricted within the group, and this produces genetic marker differences and differences in the presence of specific disease-related alleles.
I think it is B, that helps disprove it so it can't prove it.
Humans' aerobic capacity is increased by NMN during exercise training, and the enhancement is probably the result of improved skeletal muscle O2 use.
over the past ten years, studies have demonstrated the benefits of NMN for rodents' healthy ageing, increased longevity, and exercise capacity. For instance, adding NMN to one's diet improves energy generation, boosts physical stamina by over 50%, and benefits a number of physiological traits like insulin sensitivity and neuron functiAdditionally, some recent studies show that this study does, in fact, benefit humans, with NMN enhancing muscle performance in men over 60 and insulin sensitivity in prediabetic menopausal women. The topic of whether NMN has a good impact on ageing, health, and activity in younger person
