Answer:
1. Answer: Light can travel in a vacuum, and its speed is constant if the source is moving or stationary.
Light travels at constant speed in vacuum even if the source is moving or stationary. If the source is moving, the apparent frequency/ wavelength changes.
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.

<span> Two daughter cells for each parent cell undergoing mitosis.
Each daughter cell has 10 chromosomes in this example. </span>
Answer:
The correct answer will be- Non-Mendelian inheritance (incomplete dominance)
Explanation:
Incomplete dominance is a type of inheritance pattern observed in nature in which none of the two alleles completely show their effect and produces a third type of phenotype which is different from the phenotype of both the parents.
In the given question, since the cross of red flower and white flower produces a third type of flower color known as pink during F₁ generation is the result of the incomplete effect of both the alleles.
Cross
RR (red) x rr (white) = Rr (pink)
Thus, incomplete dominance is the correct answer.
