Explanation:
50%; homozygous recessive; phenotype
According to the Punnett square, offspring from these two parents have a <u>50%</u>chance of inheriting two b alleles. Individuals that inherit two b alleles are <u>homozygous recessive </u>. Inheriting two b alleles confers the <u>phenotype</u> of blue eyes.
Inheritance describes the way in which certain traits are passed onto offspring of sexual reproduction. For instance, co-dominance, both of a gene's alleles are present, and notable in the phenotype.
The nucleus is a large membrane-bound organelle that houses the genetic information, DNA, in the cell. Sequences of DNA make up genes which can have different forms called alleles and comprise the genotype. DNA is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins. These proteins, when expressed, are referred to as an organism's phenotype.

Answer:
Scientist 1
Explanation:
<em>The conclusion of scientists 1 is valid.</em>
Human activities such as burning of fossil fuels, agriculture, deforestation, etc. leads to the emission of carbon in the form of carbon dioxide into the atmosphere. <em>An increase in the population of a city will only lead to an increase in these activities and hence, an increase in the amount of carbon emitted into the atmosphere.</em>
Also, volcanic activities leads to the production of volcanic gases which is a mixture of carbon dioxide, oxides of sulfur, nitrogen, etc.
<u>However, an active volcano that is several miles away from the city might not be a major source of carbon in the air above a large city. The carbon dioxide produced from such volcanic activity thins out before reaching the city.</u>
