3. If tall eyeballs (T) are dominant to short eyeballs(t),
give the genotypes that are possible for members of Mr.
Krabbs' family.
Tall eyeballs =
1
Answer:
Tt, TT
Explanation:
Dominant genes are genes that express themselves over recessive genes. This are expressed on such individual and are visible phenotypically. While recessive genes are genes whose effect are masked and not expressed. They may be present in the genome of an individual but are not usually expressed.
For an individual with a dominant tall eye ball(T)over short eye ball(t), Tall eye ball will always be expressed as TT having similar allele or Tt with a different allele but in a dominant form.

The hydrophobic effect is related to the fact that water is most stable when it has the most hydrogen bonds and that nonpolar molecules decrease the number of those bonds. True or false
Answer:
True
Explanation:
When a hydrophobe is dropped in an aqueous medium, hydrogen bonds between water molecules will be broken to make room for the hydrophobe; however, water molecules do not react with hydrophobe. This is considered an endothermic reaction, because when bonds are broken heat is put into the system. The hydrophobic effect is considered to be the major driving force for the folding of globular proteins. It results in the burial of the hydrophobic residues in the core of the protein. It is exemplified by the fact that oil and water do not mix and was described well by G. S. Hartley in 1936. 1 Hydrophobic effect. The hydrophobic effect increases the thermodynamic activity of large hydrophobic molecules of metal complexes formed in the aqueous phase of solvent extraction systems, which promotes their transfer from the aqueous to the organic phase.

Which best describes the relationship between digestion and cellular respiration? O A. Digestion breaks foods down to simple sugar molecules, and respiration uses the sugar molecules to produce energy. O B. Digestion creates nutrients from food particles, and respiration uses the nutrients to produce energy. O C. Digestion releases oxygen molecules from food, and respiration uses oxygen molecules to produce energy. D. Digestion produces waste materials, and respiration uses the waste materials to produce energy.
Answer:
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products
