Answer:
1 black : 1 orange
Explanation:
This is a typical monohybrid cross involving a single gene coding for eye color in MendAlien. The allele for black eyes (B) is dominant over the allele for orange eyes (b). In an heterozygous state, Bb i.e. combination of both dominant (B) and recessive (b) alleles, the MendAlien will be phenotypically black.
In a cross between a heterozygous MendAlien (Bb) and an orange-eyed MendAlien (bb), two of the offsprings will have a Bb genotype and be phenotypically black-eyed which the other two will have a bb genotype and be phenotypically orange-eyed. Thus, a phenotypic ratio of 2 Bb : 2 bb will be obtained.
This is also equal to 1:1 i.e. 1 black-eyed : 1 orange-eyed.
<u>Answer:</u>
Photosynthesis and respiration are so interrelated with each other that one’s product are used as another’s reactant.
<u>Explanation:</u>
- Photosynthesis is a process used by organisms to convert 'light energy' into 'chemical energy', which is used as a source of energy for the organism.
- Respiration is a process in which glucose and oxygen is used to create ATP for the survival of the organism.
- During photosynthesis 'water and carbon dioxide' reacts in presence of light to create oxygen and glucose.
- Without photosynthesis and respiration life ceases to exist on earth.
In hot springs the rising superheated water is cooled below the boiling point by groundwater before reaching the surface. In geysers the superheated water collects in underground pockets.
