E) many of the observable characters that vary in pea plants are controlled by single genes. Answer: D Topic: Concept 14.1 Skill: Comprehension 2) A plant with purple flowers is allowed to self-pollinate. Generation after generation, it produces purple flowers. This is an example of A) hybridization. B) incomplete dominance.
3) What does the taproot system do? Often stores organic nutrients that the plant consumes during flowering and fruit production. 4) Why are root crops such as carrots, turnips, and sugar beets harvested before they flower? Because the taproot system stores organic nutrients in the root part. 5) What is the system where no roots stand out as the main one?
c) Use relative frequencies to estimate the probability that a seed will germinate. What is your estimate? P(germinate) = d) Use relative frequencies to estimate that the seed will not germinate. P(not germinate) = 3. Roll a (fair, six-sided) Die: (4 possible points) a) If you roll a single die and count the number of dots on top, what is the sample space of all possible outcomes?
Biology Lab Report Lab No. 18: Biochemical Genetics: Investigating biochemical reactions in smooth peas and wrinkled peas Results: The presence of starch in smooth and wrinkled peas Phenotype of peas Genotype of peas Color (when iodine is added) Starch present Smooth SS or Ss (dominant) Dark blue-Black Yes Wrinkled ss (recessive) Brown No Conclusion The phenotype of the peas depends in its biochemical composition, which depends on all the biochemical reactions that take place. In turn, these reactions are controlled by enzymes and whether these enzymes are present depends on whether the genotype for their production was inherited. Therefore, in the end, whether particular enzyme(s) are present will determine the phenotype of the individual. The phenotype of the peas was also different (smooth, wrinkled), meaning that the biochemical reactions that take place in the peas are different to one another.
Mung Bean Experiment Lab Report I. Introduction In this experiment, mung bean seeds are being tested for growth in populated areas. Mung beans are commonly grown in East Asia and the Orient. II. Purpose and Hypothesis The purpose of this experiment is to discover mung bean plant growth habits in crowded, or no crowded areas.
Step By Step Examples of Using the Pythagorean Theorem Example 1 (solving for the hypotenuse) Use the Pythagorean theorem to determine the length of X | | Step 1) Identify the legs and the hypotenuse of the right triangle. | The legs have length '6 and '8' . 'X' is the hypotenuse because it is opposite the right angle. See Picture | The hypotenuse is red in the diagram below: Step 2) Substitute values into the formula (remember 'c' is the hypotenuse) | A2 + B2 = C2 62 + 82 = X2 | Step 3) Solve for the unknown | | Example 2 (solving for a Leg) Use the Pythagorean theorem to determine the length of X | | Step 1) Identify the legs and the hypotenuse of the right triangle. | The legs have length '24' and 'X' are the legs.
8. Calculate the average yield from the three pots of each seed variety under a particular infestation level. Record all the averages in the data table. Results and Analysis Results Table 1: Average Yield for each seed variety at no, low, and high infestation levels Seed Variety | Level of ECB Infestation | Pot 1 Yield | Pot 2Yield | Pot 3Yield | Average Yield | BT 123 | None | 160.1 | 164.8 | 164.2 | 163.0 | | Low | 164.0 | 162.6 |
Each bag of color candies and the amount in each bag was documented. Step two: In step two of the project the Excel data program was used in order to document color proportions and the number of candies in each bag. Each bag was separated into colors and the numbers per bag. For example my first bag had a total of 56 pieces. Each color had the following number of pieces: Green 16, Orange 10, Brown 6, Yellow 9, Red 6, and Blue 9.
A comparative analysis of the consensus amino acid sequence of different NDV genotypes in class I was performed (Table 4). The substitution mutations S30A was found in the F protein of NDV strain CK-065-201306, in addition, A93T and E104D were found in CK-026-201306. 3.3 The characteristics of chickens after infection with the CK-65-2013 and CK-26-2013 strains To analyze the characteristics of two novel class I NDV strains after infection in poultry, two isolates were inoculated intranasally with 1-day-old SPF chickens showed that no clinical signs, no lesions and no mortalities were observed in all groups during the course of the experiment (Table 5). This result indicates that two novel class I NDV strains have no pathogenic ability to
There are many cover crop species like the Legume and Non-Legume species. Need for study: What are the economics of using cover crops in field crop systems? Initial studies conducted at Kellogg Biological Station compared continuos corn to first year corn following frost-seeded red clover in wheat. These studies have shown a $40/A gross return minus costs when cover crops were incorporated into a crop rotation. Also cover crops help in agriculture by giving farmers the measured amount of how much water is running out of the soil and what to do with those results.
