Answer:
1. tall (or heterozygous)
2. 3:1
3. carriers
4. Each parent organism contributes one copy of its alleles in a seemingly random fashion to its offspring, as meiosis to create gametes (egg or sperm cells) reduces the number of genes by half. Therefore, each gamete contributes only one allele.
5. A Punnett square is a diagram used to map out the possible genotypes of a child given the genotypes of its parents. In a Punnett square, the genotype of one parent is listed in the first row of the square, and the genotype of the second parent is listed in the first column. Then, in the middle squares, all possible genotypes of their offspring are listed, and the phenotypes are calculated using the law of dominance.
6. Purebred strains of organisms always produce heterozygous offspring in the first generation, with all members of the first generation exhibiting the dominant trait for the gene of interest. The second generation typically has a 3:1 mix of dominant and recessive phenotypes, respectively.
7. Punnett squares predict that the second generation of two distinct purebred homozygotes for a trait will have a 3:1 ratio of dominant to recessive traits. Mendel did careful statistical analysis on his hybridization experiments and found that, for each of his seven characteristics of interest, the ratio was approximately, but not exactly, 3:1. Therefore, Mendel's experimental observations match the predictions of Punnett squares quite well.

Complete Question
Ruben Ward has been weight lifting and eating a high protein diet. Below is Ruben's profile and what he ate for a day. He entered his profile information and food intake into Diet & Wellness Plus and then pulled the Diet & Wellness Plus Reports. View Ruben’s Intake vs Goals and Macronutrient Ranges Reports and then answer the questions below. Profile for Ruben Ward 1. Age: 19 years old 2. Gender: Male 3. Height: 5 ft, 8 inches 4. Weight: 205 lbs 5. Non-Smoker 6. Activity Level: Active
Ruben has recently taken up weight lifting, and his friends at the gym mistakenly believe they should eat more protein to build muscle. The DRI for protein for healthy adults is 0.8 g per kg body weight. If Ruben weighs 205 lbs (93 kg), how many grams protein per kg body weight did he eat on this day?
a. 5.37 g/kg
b. 10.33 g/kg
c. 3.55 g/kg
d. 4.88 g/kg
Answer:
c. 3.55g/kg
Explanation:
RDI means Recommended Dietary intake. It is the required amount of a nutrient expected to be taken by an individual for optimal health.
The Recommended Dietary Intake I'd protein falls withing the range of 0.8 grams per kg to 1.8 grams per kg
For Reuben
He weighs 93 kg
If Reuben consumed 330 grams of protein, his grams of protein per kg body weight is
330 grams ÷ 93kg
= 3.55g/kg.
Answer:
The correct answer is D) requires phosphorylase activity.
Explanation:
Signals transmitted with the use of phosphorylation requires the presence and activity of an enzyme phosphorylase (also called Kinase) that can add phosphorus groups to proteins or other molecules in order for them to become messengers in the signaling pathway.
The answer is C
Plasmids are conferred through horizontal gene transfer in bacteria. The ‘male’ bacteria develops a structure called pili that then attaches to the ‘female’ bacteria. It then transfers it’s replicated plasmid to the ‘female’ bacteria in a process called conjugation. This bacteria will hence have desirable traits that are coded for by the transferred genetic material ,such as antibiotic resistance, after a process called recombination.
Answer:
C) Bacteria congregated in these areas because these areas had the most oxygen being released.
Explanation:
Below is the full question:
Theodor W. Engelmann illuminated a filament of algae with light that passed through a prism, thus exposing different segments of algae to different wavelengths of light. He added aerobic bacteria and then noted in which areas the bacteria congregated. He noted that the largest groups were found in the areas illuminated by the red and blue light.
What did Engelmann conclude about the congregation of bacteria in the red and blue areas?
A) Bacteria released excess carbon dioxide in these areas.
B) Bacteria congregated in these areas due to an increase in the temperature of the red and blue light.
C) Bacteria congregated in these areas because these areas had the most oxygen being released.
D) Bacteria are attracted to red and blue light and thus these wavelengths are more reactive than other wavelengths.
E) Bacteria congregated in these areas due to an increase in the temperature caused by an increase in photosynthesis.
The most efficient region of white light for photosynthesis has been found to be the blue and red region of the white light. Hence, these two regions must have had the most oxygen being released because they are the regions with the highest rates of photosynthesis.
<em>Aerobic bacteria thrived better in the regions illuminated by red and blue light because these regions had the highest oxygen production as a result of having the highest rates of photosynthesis.</em>
<em>The correct option is C.</em>
