Answer:
ATP synthase will hydrolyze ATP and pump protons into the intermembrane space.
Explanation:
Under normal conditions, the intermembrane space of mitochondria has higher proton ion concentration than the matrix. The inner mitochondrial membrane is impermeable to protons. The concentration gradient drives pass movement of protons through proton channels and the energy is used to drive the synthesis of ATP. The synthesized ATP molecules are released in the matrix.
If the matrix has higher ATP concentration and the proton concentration in intermembrane space is low, ATP synthase would use the energy of hydrolysis of ATP to pump protons from matrix towards intermembrane space. These conditions would not support ATP synthesis.
Answer:
Option D, Five radish plants are grown in sunlight, while another five radish plants are kept in the dark.
Explanation:
In a controlled experiment, impact of one independent variable is studied on the dependent variable.
Here in this study sunlight is the independent variable while the radish plant is dependent variable.
The researcher wants to study the effect of sunlight on radish plants when they are exposed to it and compare it to the effect created on radish plants that are kept in dark.
Hence option D is correct.
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.
