The chemical route to entry in the given scenario will be by absorption. The correct option is d.
<h3>What is absorption?</h3>
A process by which one thing becomes a part of another, or the process by which something soaks, either literally or metaphorically is referred to as absorption.
The missing options are :
- Inhalation
- Ingestion
- Injection
- Absorption
As in the given scenario, the solution gets spilled on the arms of Howard and is having a burn mark, which means the solution is absorbed in the skin and is the chemical route of entry.
Thus, the correct option is d.

Because they represent the leftover building blocks of the solar system-scientists can study these and learn about the composition of the solar system.
Because they need it to get protein and create it. Protein helps the plants grow.
Answer:
the soil was dry so i watered your plant
Answer:
75% of their offsprings will be red birds, and 25% will be with birds, this is the phenotype.
The genotype will be BB, Bb, and bb.
Explanation:
he information that we have is that B is the dominant allele for red feathers in a bird, and b is the recessive allele for white feathers in a bird.
If we cross two heterozygous birds that means that both progenitors are Bb, if we draw a Punnet Square we can see that 75% of the offsprings will be red birds, and 25% will be white birds, this is the phenotype, which is what we can physically see of the genes.
The genotypes will be BB, Bb, and bb, these are the different combinations of genes that can happen, and that explains why a bird is red or white, which is due to the dominance of one allele over the other.
<u> ║ B ║ b ║</u>
<u>B║ BB ║Bb ║</u>
<u>b║ bB ║ bb ║</u>
