Left-handedness (r) is recessive in humans and right-handedness is dominant (R).
Tracy, a left-handed woman, and whose mother and brother are also left-left handed,
marries Sa who is right-handed. Sam's mother is left-handed and his father and sister
are right-handed. What is the expected genotypic ratio of the children Sam and Tracy
might have?
ORr:2rr:ORR
1Rr:2rr:1RR
2Rr:2rr:ORR
The expected genotypic ratio of their children is 2Rr:1rr:1RR.
What is Genotype?This can be defined as the genetic composition of an organism. Since Sam and Tracy possess heterozygous traits, their genotypes will be Rr and Rr.
When this is crossed , we will get :
Rr × Rr
RR Rr Rr rr
This means the genotypic ratio will be 2Rr:1rr:1RR.

What happens when enzymes are heated to a high temperature? The enzymes die.
The enzymes' amino acid sequence changes.
The enzymes remain the same.
The shapes of the enzyme are denatured.
Answer:
The shapes of the enzyme are denatured
Explanation:
High temperatures will break the forces that hold them together and control the enzymes.
The enzyme, including it's activity site will eventually change shape and the substrate will no longer fit; proving them ineffective.

Which of the following best describes the compositional layers of the earth? a. All layers of the Earth below the crust are liquid. b. The only liquid layer of the earth is the mantle. c. The crust floats on top of the outer core. d. Some layers of the earth are liquid, and some are solid. Please select the best answer from the choices provided A B C D
Answer:
The answer to this question is "D" Some layers of the earth are liquid, and some are solid.Explanation:
Core, mantle, and crust are divisions based on composition. The crust makes up less than 1 percent of Earth by mass, consisting of oceanic crust and continental crust is often more felsic rock. The lithosphere is composed of both the crust and the portion of the upper mantle that behaves as a brittle, rigid solid.
The option that correctly describes the compositional layers of the earth is : ( D ) Some layers of the earth are liquid, and some are solid.
Earth compositionThe earth is composed of the Core, mantle, and crust which are categorised based their varying composition. The crust consists of the oceanic crust and continental crust. WhileThe lithosphere is composed of both the crust and the portion of the upper mantle which are similar to brittle rigid solid.

Which step in the process of photosynthesis is dependent on light energy?
A.splitting of water into hydrogen and oxygen
B.combining carbon and oxygen into carbon dioxide
C.splitting carbon dioxide into carbon and oxygen
D.combining hydrogen and oxygen to form water
Answer:
D. Combining hydrogen and oxygen to form water.
Explanation:
The process of photosynthesis which is dependent on light energy is the
combining of hydrogen and oxygen to form water.
Photosynthesis involves the reaction between carbondioxide and water to
form Starch and oxygen. The water molecules however have to be split
because of movement of electrons in which the water become oxidized and
carbondioxide reduced.
This process however have to be done in the presence of sunlight which
serves as a precursor.
