Bruce Wallace (1963) established a laboratory population in which the recessive allele lt was at a frequency of 0.5. He propagated the population for 10 generations, and determined the frequency of lt each generation.
a. True
b. False
Answer:
a. True
Explanation:
Bruce Wallace was a professor emeritus of genetics who performed many population studies. He worked in 1958 at the University of Cornell as a professor of genetics. In 1963, he performed a population study wherein the recessive allele It was at a frequency of 0.5. The population was propagated for 10 generations and the frequency of It for each generation was determined.
The result of this study showed that lt/lt died without reproducing, whereas, individuals with genotype +/+ were normal.
Hannah and Becca are fraternal twins. They are both athletic. Hannah is a swimmer, and Becca is a runner. Which sister would have denser bones?
According to the question, Hannah would have denser bones because her bone would get heavier due to water absorption through epithelial cells.
What is Bone density?Bone density may be characterized as a type of measurement that significantly involves the accumulation certain amount of minerals contained in a certain volume of bone. This measurement is generally used to find out and treat serious bone loss, called osteoporosis.
When an individual is practicing in a swimming pool constantly for a longer period of time, it is observed that his/her bone density must be increased as compared to those who are running or performing other types of athletic activities.
Therefore, according to the question, Hannah would have denser bones because her bone would get heavier due to water absorption through epithelial cells.

Which of the following statements about the process of science is accurate?
A. Science does not use evidence and data collected to advance our understanding of natural and supernatural phenomena.
B. Science attempts to solve a problem by evaluating the plausibility of only one solution without considering other possible explanations.
C. Science is a systematic method of procedures designed to answer questions by evaluating evidence.
D. Science can answer all questions regarding the human experience and personal values.
Answer:
C
Explanation:
The correct answer would be that science is a systematic method of procedures designed to answer questions by evaluating evidence.
Science is generally defined as man's way of obtaining knowledge about his natural environment through the evaluation of evidence available to him. Science follows a laydown procedure to obtain evidence through data collection, analyze such, and arrive at reasonable conclusions. This laydown procedure is referred to as the scientific method.
Hence, that science does not use evidence and data collected to advance the understanding of natural and supernatural phenomena is an antithesis to what science represents.
Science only arrive at conclusion after evaluating all available evidence associated with a phenomenon. That it attempts to solve a problem by evaluating the plausibility of only one solution without considering other possible explanations is, therefore, not true.
Science continuously seeks knowledge in order to understand the natural world. Hence, while science has been able to answer several questions about man and his natural world, several questions still have their answers pending. That science can answer all questions regarding the human experience and personal values is, therefore, far from being true.
The only accurate option that describes science is C.
The best description of science is that science is a systematic method of procedures designed to answer questions by evaluating evidence.
What is science?Science is defined as the process by which man obtain knowledge about his natural environment through observation and critical evaluation of facts and evidences in order to arrive at a conclusion.

What is poisonous enough to kill 100,000 turkeys? That’s the question asked by scientists who studied a mass die-off of turkeys in Great Britain. It turned out that all the turkeys had eaten peanuts from Brazil. A fungus was growing on the peanuts. The fungus produced a dangerous poison called aflatoxin. Aflatoxins cause stomach pain, lung failure, cancer, and death in people and animals.
Farmers make a great effort to prevent fungi from growing on their stored crops. In a pile of grain or nuts, fungi have plenty of food and living space. The best way for farmers to prevent fungi from growing is to make sure there is not enough for fungi to survive and grow.

D. Spell out different instructions depending on their order
Answer: The answer is D.
Explanation: It makes the most sense and explains how both the aplhebet and DNA have simrialities.
The building blocks of DNA are like alphabet letters because they spell out different instructions depending on their order. Thus, the correct option for this question is D.
What are the building blocks of DNA?The building blocks of DNA are known as nucleotides. These nucleotides are made up of three parts. They are as follows:
A phosphate group.A pentose sugar.Nitrogenous base.These nucleotides are arranged by one another with the help of a linkage known as phosphodiester linkage. Nitrogenous base in nucleic acids like DNA includes Adenine, Thymine, Cytosine, and Guanine. In the DNA, they are represented as A, T, C, and G. Due to this, the building blocks of DNA are like alphabet letters.
Therefore, the building blocks of DNA are like alphabet letters because they spell out different instructions depending on their order. Thus, the correct option for this question is D.
