A recessive trait inheritance could be more prevalent in a population than the dominant because mutation could occur because the mating does not have a wide variation causing a lethal gene or an autosomal sex link to be easily passed on the offspring
<h2>c) option is correct </h2>
Explanation:
- Each synovial joint has a fibrous capsule surrounding the joint, which helps hold the bones together, along with the ligaments (which join bone to bone) and tendons (which join muscle to bone)
- The joint capsule is lined by the synovial membrane, which manufactures the synovial fluid
- The synovial fluid is located within the joint cavity of a synovial joint and has three primary functions: Lubrication
, nutrient distribution and shock absorption
The valinomycin treatment caused a decrease in the activity of the mitochondria.
Explanation:
When valinomycin treatment was given, the rate of ATP production is reduced in the cells treated. Since mitochondria are involved in ATP synthesis, it clearly shows that valinomycin inhibits mitochondrial action.
Valinomycin being a selective K+ ionophore, it can transfer potassium ions through selective lipid membranes. This can cause potassium effux in organelles like mitochondria leading to marked loss of potential of mitochondrial membrane and apoptosis in cells.
The effux of K+ ions forms a complex with valinomycin and slows down the mitochondrial part of ATP synthesis by reducing the proton-motive force, but does not block any oxygen electron transfer

Answer:
Mutations are one way for bacteria to become resistant to antibiotics. Some spontaneous mutations (or genes that have been acquired from other bacteria through horizontal gene transfer) may make the bacterium resistant to an antibiotic (See: Resistance mechanisms for information about how bacteria resist antibiotic action). If we were to treat the bacterial population with that specific antibiotic, only the resistant bacteria will be able to multiply; the antibiotic selects for them. These bacteria can now increase in numbers and the end result is a population of mainly resistant bacteria.
