Absolute Brightness
Absolute brightness represents
the total amount of energy emitted from a celestial object. It is the measure
of the true brightness of a star or other celestial object as it would be as
seen from a standard distance<span> of
exactly 10 parsecs (32.6 light-yea</span>rs). The more luminous an object, the smaller the
numerical value of its absolute magnitude or brightness.

Answer: Option C.
Haemoglobin binds Hydrogen ion after carbondioxide enters red blood cells.
Explanation:
Haemoglobin is the protein in the red blood cells that help to transport oxygen in the blood. It is an iron compound. Haemoglobin acct as buffer by binding to acid or hydrogen ion in the blood when carbondioxide enters the blood, to remove the acid in the blood before it changes the blood pH.
Tall pea plant was crossed to dwarf plant. The frequency of dwarf plants in F2 will be 0%.
- A true breeding pea plant is one that, after self-fertilization, only bears offspring with the same traits.
- True breeding organisms are those that share the same genes for the desired traits and are genetically comparable.
- These animals possess homozygous alleles. If the alleles are distinct, only one of the gene's alleles—referred to as the dominant gene—will be expressed.
- The other allele, referred to as the recessive one, has no effect.
According to the given cross:
TT X tt (parents)
Tt Tt Tt Tt (offspring) all tall
Hence the percentage of dwarf individuals is 0.

The surface of a leaf has many tiny pores, called stomata. The stomata allow carbon dioxide into the leaf so that photosynthesis can occur. They also allow water to leave the leaf by transpiration. Plants that grow in full sunlight usually have most of their stomata on the shaded undersides of their leaves.
