Advantages of using solar energy are pollution-free, noise-free, on installation it produces free energy, clean and renewable. Disadvantages include high cost, energy dependent on sunlight exposure, power stations are expensive to build and devices powered by solar energy cannot be used at night
Answer:
C)The luminal side of the thylakoid membrane has a higher pH than the stromal side.
Explanation:
During the photophosphorylation, the electrons move through many electron carriers which allow the transport of hydrogen ions in the luminal side against the concentration gradient. This allows the increase in the Hydrogen ion concentration to the luminal side of thylakoid membrane and reduction in the hydrogen ion concentration of the stromal side.
Therefore due to the increased concentration of H⁺ ions in lumen during the photophosphorylation, the lumen has a lower pH than the stroma. During photophosphorylation, the pH of lumen decreases up to 4 and the pH of stroma increases up to 8. So the false option is C.

What is inherited disease?
Genetic factors play a role in almost all health conditions and traits, but there are some conditions in which genetic alterations play a role in almost all of the causes that cause the condition.
Genes are passed from parent to child, so are DNA changes within the gene. DNA changes can also occur spontaneously, first appearing in children of unaffected parents. This is called a new mutation, and the word mutation means change.
Therefore, (30%) gorilla babies die within the first few months of their lives because of inherent weakness of the infant or disease.

Answer:
0.32
Explanation:
Hardy Weinberg equilibrium states that the frequency of allele will remain the same in the absence of disturbances such mutation,no gene flow, no selection, random mating and infinite population size
the equilibrium is defined the equation
p² + 2pq + q²
where q² = f, frequency of the homozygous recessive allele, p² = f, of the homozygous dominant allele and 2pq is the frequency of the carrier of the dominant + rh blood factor
q² = 0.04
q = √0.04 = 0.2
and p + q = 1
p = 1 - 0.2 = 0.8
therefore 2pq = 2 × 0.8 ×0.2 = 0.32
