Answer:
A story that might be a good human interest story would be the vaccines for corona. Everyone these days are waiting desperately for corona to end. Talking about a vaccine might give them hope, and it would be nice to see how the scientist and doctors truly care for the people. Maybe encourage them to wear the masks until the vaccines come out?
Answer:
Cb>Cy>Co>Cr
Explanation:
First of al we need to do the Punnett square. As a result we get the genotypes:
CyCb
CyCr
CoCb
CoCr
Because there are no red frogs, red is the least dominant as it isn't expressed in any genotype.
Half of the progeny are blue and half of the possible genotypes contain the blue allele meaning that blue is expressed in all genotypes. This means that blue is the most dominant.
The only alleles left are yellow and orange. We can deduce that yellow is more dominant than orange because one of the parent frogs is yellow and contains the genes for yellow and orange.
As a result blue is the most dominant, yellow is the second most dominant, orange is the third most dominant and red is the least dominant.
Genes and the complete set of genes within an organism’s genome is called its genotype
The rate of diffusion increases as temperature increases.Hence, the rate of diffusion will be the greatest in boiling water then warm water and cold water at last
- The movement of molecules along a concentration gradient is known as diffusion.
- It is a significant process that all living things go through. Diffusion facilitates the flow of materials into and out of cells.
- Increased energy from higher temperatures causes the molecules to move more quickly, speeding up the diffusion process.
- Lower temperatures cause the molecules' energy to drop, which lowers the diffusion rate.
- The rate of diffusion increases with increasing concentration differences.
- The particles will move and mix more quickly at a greater temperature because they will have more kinetic energy.
Hence, the diffusion rate will be boiling water>warm water>cold water

The main organ in mammals respiration is the lungs<span>. The lungs are actively ventilated via a suction-pump mechanism of inhalation and exhalation. Breathing is dependent upon the rib muscles and the </span>diaphragm<span>, a structure shaped like a dome-shaped floor just beneath the lungs. </span>
<span>Inhalation happens when the rib cage opens up and the diaphragm flattens and moves downward. The lungs expand into the larger space, causing the air pressure inside to decrease. The drop in air pressure inside the lung makes the outside air rush in. </span>
Exhalation is the opposite process. The diaphragm and the rib muscles relax to their neutral state, causing the lungs to contract. The squashing of the lungs increases their air pressure and forces the air to flow out.
