Explanation:
Which of the following is an example of genetic engineering?
A) manipulating potato genes to improve nutritional value, growth and flavor
B) creating a new identical mouse from the single cell of another mouse
C) a trait that is not advantageous disappearing over multiple generations
D) breeding two fast racehorses to produce offspring that have superior skills
5. Read the scenarios below. For each of the scenarios, identify the following (you should identify the 3 for EACH of the scenarios):
Control Group Independent Variable Dependent Variable
A. John thinks that a special juice will increase the productivity of workers. He creates two groups of 50 workers each and assigns each group the same task (in this case, they're supposed to staple a set of papers). Group A is given the special juice to drink while they work. Group B is not given the special juice. After an hour, John counts how many stacks of papers each group has made. Group A made 1,587 stacks, Group B made 2,113 stacks.
B. Candy notices that her shower is covered in a strange green slime. Her friend Belinda tells her that coconut juice will get rid of the green slime. Candy decides to check this out by spraying half of the shower with coconut juice. She sprays the other half of the shower with water. After 3 days of "treatment" there is no change in the appearance of the green slime on either side of the shower.
C. Elisa is working on a science project. Her task is to answer the question: "Does Grow Long (which is a commercial hair product) affect the speed of hair growth?" Her family is willing to volunteer for the experiment.
Answer:
A.
1) Control Group: Group B (not given the special juice)
2) Independent Variable: Special juice given to Group A
3) Dependent Variable: Number of stacks of papers each group made
B.
1) Control Group: The side of the shower sprayed with water
2) Independent Variable: Coconut juice sprayed on one side of the shower
3) Dependent Variable: Appearance of green slime on both sides of the shower
C.
1) Control Group: No treatment
2) Independent Variable: Grow Long (commercial hair product)
3) Dependent Variable: Speed of hair growth
Explanation:
In what ways are sexual and asexual production in plants similar, and in what ways do they differ?
Answer: Plants reproduce in two ways: sexually and asexually. . By fusing gametes, sexual reproduction generates children. As a result, the offspring are genetically distinct. Asexual reproduction results in the formation of new people without the fusing of gametes.
Sexual and Asexual Reproduction :
Although there are many distinct methods used by living creatures to reproduce, the majority of these methods may be classified as either sexual or asexual reproduction.
Offspring produced by asexual reproduction are genetically identical to either of their parents. Two parents contribute genetic material during sexual reproduction to create distinct children.
There are benefits and drawbacks to both sexual and asexual reproduction, which is why some creatures use both.
Explanation:
Signal Noise
Information in an electronic signal can be affected by noise. Noise is any unwanted disturbance in a signal. If you've ever seen interference when watching TV, then you've witnessed signal noise.
There are many causes of noise, and it can be introduced into a signal when the information is recorded, processed, transmitted, or received.
6. Suppose the analog signal shown here is from a music program on the radio. How do you think the music would be affected by the noise when you listen to it on the radio? Explain
Answer:
[tex]5( + [/tex]
[tex] \div \div \div \div \div \div \div [/tex]
[tex] log_{ \cot(?) }(?) [/tex]
Answer: The noise in an analog signal can affect the quality of the signal and cause distortion in the original waveform. In the case of a music program on the radio, noise can cause unwanted sounds, such as static, crackling, or hissing, which can interfere with the quality of the music being played.
The effect of noise on the music depends on the level and type of noise, the sensitivity of the receiver, and the quality of the equipment used to process and amplify the signal. In general, the more noise that is present, the more noticeable the degradation of the music will be.
However, it's important to note that some types of music may be more resistant to noise than others. For example, music with a lot of bass or percussion may mask some of the noise, while music with a lot of high-frequency content may be more affected by noise. Additionally, some listeners may be more sensitive to noise than others and may notice the degradation of the signal more readily.
Explanation:
Which animal would most likely be found in a warm area near the equator that gets around two meters of rainfall per year?
A) Deer
B) Zebra
C) Orangutan
D) Wolf
Answer:
B) Zebra.
Zebras are well adapted to live in warm areas near the equator and can be found in grasslands and savannas where they graze on grasses. They are also able to tolerate a wide range of rainfall patterns, but are commonly found in areas that receive around 2 meters of rainfall per year.Deer are more commonly found in cooler areas with forests, and wolves typically live in colder climates such as forests or tundras. Orangutans are primates that live in tropical rainforests and are adapted to living in areas with high rainfall levels. However, they are not typically found in open savannas or grasslands.
A fertile valley has farms and a small town. The valley is surrounded by hills, but these hills are not good for farming or living. Over time, the town expands.
How will the town’s growth most likely affect the availability of farmland in the valley?
1. The availability of farmland will decrease.
2. The availability of farmland may increase or decrease.
3. The availability of farmland will remain unchanged.
4. The availability of farmland will increase.
3, because the land was already not good for farming.
Why it was important that Gregor Mendel used thousands of pea plants in his experiments? Would Mendel have found the same results if he had used only twenty plants? Explain.
Answer:
Explanation:
Gregor Mendel used thousands of pea plants in his experiments to ensure that his results were accurate and reliable. By using a large sample size, he was able to reduce the effects of chance and random variation in his experiments. This is important because biological systems are complex and variable, and small sample sizes can lead to inaccurate or misleading results.
Mendel's experiments involved crossing pea plants with different traits (e.g., tall vs. short, yellow vs. green), and he counted the number of offspring with each trait. He found that the offspring followed predictable patterns of inheritance, which he summarized in his laws of inheritance.
If Mendel had used only twenty plants in his experiments, he may not have obtained the same results. With a small sample size, chance events can have a greater impact on the results. For example, if he crossed two pea plants with different traits and obtained only a few offspring, it's possible that chance events (such as mutations or environmental factors) could have influenced the results. This could lead to false conclusions about the inheritance of the traits.
Therefore, using a large sample size was critical to Mendel's success in developing his laws of inheritance. It allowed him to detect patterns that were consistent across many different crosses, and to demonstrate that these patterns were not the result of chance variation.
