Answer:
Lithium
Explanation:
<em>"Like the other alkali metals, lithium has a single valence electron that is easily given up to form a cation. Because of this, lithium is a good conductor of heat and electricity as well as a highly reactive element, though it is the least reactive of the alkali metals."</em>
Answer:
The instructions for making proteins are coded in the (cytoplasm / <u>DNA</u> / endoplasmic reticulum / nucleus) of a cell. In a eukaryotic cell, these instructions are located in the (cytoplasm / DNA / endoplasmic reticulum / <u>nucleus</u>).
Explanation:
The genetic code is contained in DNA, or deoxyribonucleic acid. This is usually the same among most organisms, save some RNA viruses. But in eukaryotes, the DNA is in the nucleus, whereas in prokaryotes the DNA is in the "nucleoid region", or a twisted up section near the middle of the cell.
Answer:
Longitudinal
Explanation:
Longitudinal waves have the same direction of vibration as their direction of travel. This means that the movement of the medium is in the same direction as the motion of the wave. Some longitudinal waves are also called compressional waves or compression waves.
1. In snapdragons, the color of the flower is controlled by incomplete dominance. The two alleles are red (R) and white (r). What is genotype of a pink snapdragon? Answer Choice Feedback A. or Incorrect. This snapdragon would be white. B. RR Incorrect. This snapdragon’s phenotype would be red. C. Rr Correct! Since the snapdragon is controlled by incomplete dominance, one allele for red (R), and one for white (W) would result in a pink flower. D. Rw Incorrect. This is not written correctly 2. If a pink-flowered plant is crossed with a white-flowered plant what is the probability of producing a pink-flowered plant? (Hint: Draw a Punnett square to help you answer the question) Answer Choice Feedback A. 25% Incorrect. The genotype for the pink flower is Rr and the genotype for the white flower is or. This would lead to a 50% chance of the offspring having a phenotype of pink. B. 50% Correct! The genotype for the pink flower is Rr and the genotype for the white flower is rr. This would lead to a 50% chance of the offspring having a phenotype of pink. C. 75% Incorrect. The genotype for the pink flower is Rr and the genotype for the white flower is or. This would lead to a 50% chance of the offspring having a phenotype of pink. D. 0% Incorrect. The genotype for the pink flower is Rr and the genotype for the white flower is or. This would lead to a 50% chance of the offspring having a phenotype of pink. 3. Bernadette is blood type O. She has two sisters. One sister has blood type A and the other has blood type B. Using this information and your knowledge of how blood type is determined, determine the genotypes of Bernadette’s parents for this trait. Answer Choice Feedback A. I Ani, IB I Correct! The genotype for type O blood (Bernadette’s type) is “ii”, so both parents must have at least on “i”. Since one sister is type B, one parent must have the IB allele. Since the other sister is type A, then one parent must have the IA allele. B. I A I A, IA I An Incorrect. This would result in children with only type A blood. C. I B me B, IB I B Incorrect. This would result in children with only type B blood D. I B I, IB I Incorrect. This would result in offspring with either type O blood or type B.
