the cells split into two identical daughter cells during cytokinesis
Moving from the shade into the sun, removing a sweater, curling up in a ball all are the examples of behavioral mechanisms for modifying heat loss via conduction and radiation.
What is heat loss?
- Heat transfer from one material to another can occur intentionally or accidentally.
- Conduction, convection, and radiation are possible mechanisms for this.
- When a component comes in direct touch with another component, whether it is insulated or not, conduction frequently happens.
- Convection happens when an air barrier surrounds a pipe, electric heater, or other component.
- When there is no touch and heat travels in waves, it is called radiation.
Here are some typical heat loss regions that designers of heating equipment should take into consideration:
- uncovered surfaces
- Insulated surfaces that are horizontal or vertical
- Water is present.
- surfaces with paraffin or oil
- Wind speed has an impact.
Hence, all are the examples of behavioral mechanisms.

Answer:
Option B, Rr pp × rr Pp
Explanation:
Given
Walnut Comb is produces when one dominant allele R is present at one gene locus and at least one dominant allele P is present at a second gene locus - R* P*
Rose Comb - at least one dominant allele is present at the first locus and two recessive alleles are present at the second locus - R* pp
Pea comb - two recessive alleles are present at the first locus and at least one dominant allele is present at the second - rr P*
Single comb - two recessive alleles are present at the first and the second locus - rrpp
Parent are rose combed and pea combed
For being rose genotype must be R* pp
and for being pea combed genotype must be rr P*
Rr pp x rr Pp
will produce
Walnut comb with genotype Rr Pp
Single comb with genotype rrpp
and pea comb with genotype rrPp
Hence, option B is correct
