If false, please make it a correct statement. A rancher uses a particular chicken for breeding purposes because, on average, she observed that the chicken laid more eggs than other chickens. The rancher selecting the desirable trait would be considered an example of natural selection.
a) true
b) false
Answer:
b) false
Explanation:
The given statement is false. the selection process used by the rancher is an example of artificial selection and not natural selection.
Artificial selection is defined as the selection process done by humans on the basis of desirable characters while in natural selection the selection is based on the adaptive characteristics of animals. In the given example rancher choses a desirable character of chicken that lays more eggs.
Hence, the given statement is "false".
What does one newton exerted over a distance of one
meter equal?
Answer:
One Joule.
Explanation:
One newton exerted over a distance of one meter equal to one joule.
Joules is the S.I unit used for the measurement of scientific quantities such as work and energy and it was named after the prominent English physicist, James Prescott Joule.
Given the following data;
Force = 1N
Distance = 1N
Therefore, we know these parameters or quantities are directly related to work.
Mathematically, work done is given by the formula;
Work done = force * distance
[tex] W = F * d[/tex]
Where,
W is the work doneF represents the force acting on a body. d represents the distance covered by the body.Substituting into the equation, we have;
[tex] W = 1 * 1[/tex]
Work done = 1 Joule.

Explain how you found out that Lucy has ADA-SCID
Answer:
The first part of finding out Lucy having ADA-SCID was when I realized there were no HIV proteins in her blood, getting rid of the possibility of her having HIV. Then, I realized she had a high number of Deoxyadenosine in her blood. This proves she has ADA-SCID because when the ADA doesn't work you find excess amounts of Deoxyadenosine in the blood.

Why do stems have bark? What does the phloem do?
Answer:In old stems the epidermal layer, cortex, and primary phloem become separated from the inner tissues by thicker formations of cork. Due to the thickening cork layer these cells die because they do not receive water and nutrients. This dead layer is the rough corky bark that forms around tree trunks and other stems.

Two Drosophila with genotypes AABBCC and aabbcc are crossed to produce a heterozygous offspring, AaBbCc (the gene order is unknown). This AaBbCc Drosophila is crossed with an aabbcc Drosophila, resulting in the offspring below: Number: Phenotype: 600 ABC and abc 200 AbC and aBc 150 ABc and abC 50 Abc and aBC a. Which phenotype represents the double crossovers
Answer:
The double recombinant individuals are less frequent ---> Abc and aBC
Explanation:
We can know if genes are linked, by looking at the progeny distribution. In a tri-hybrid cross, If individuals, whose genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1:1:1:1:1. If we observe a different distribution, meaning that phenotypes appear in different proportions, we can assume that genes are linked in the heterozygote parent.
We can recognize the parental gametes because their phenotypes are the most frequent in the descendants, while the double recombinants are the less frequent. Finally, the simple recombinant gametes are the ones with intermediate phenotypes frequencies.
In the present example, the phenotypic ratio shows different proportions than the expected ones if they were not linked.
We can recognize the parental gametes in the descendants because their phenotypes are the most frequent,
ABC and abc 600while the double recombinants are less frequent.
Abc and aBC 50And simple recombinant gametes produced by the cross, which frequencies are intermediate.
AbC and aBc 200 ABc and abC 150a. Which phenotype represents the double crossovers
The double recombinants are less frequent ---> Abc and aBC

Organisms depend on the environment, which is made of living and nonliving things. The correct option is C.
What is environment?The environment can be defined as the sum of all living and non-living elements and their effects on human life.
Non-living or abiotic elements include water, land, sunlight, rocks, and air, while all living or biotic elements are animals, plants, forests, fisheries, and birds.
Our environment provides numerous benefits, including the air we breathe, the food we eat, and the water we drink, as well as the numerous materials required in our homes, workplaces, and leisure activities.
Healthy ecosystems clean the water, purify the air, maintain our soil in good condition, regulate the climate, recycle nutrients, and provide us with food.
They supply raw materials and resources for pharmaceuticals and other uses. They are the foundation of all civilizations and the backbone of our economies.
Thus, the correct option is C.

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.

3. What does the salt do?
4. What was the purpose of cooling the mixture?
5. What does the cold ethanol do?
6. Why can't we use room temperature ethanol?
7. Why are strawberries classified as octoploids?
Answer:
3.You might think this should mean you need to cut out salt completely, but salt is actually an important nutrient for the human body. Your body uses salt to balance fluids in the blood and maintain healthy blood pressure, and it is also essential for nerve and muscle function.
4.Cooling the mixture is to prevent the DNA from being degraded by the heating.
5.The ethanol pulls water from the DNA molecule so that it then collapses in on itself and precipitates. The DNA will become visible as white mucous strands that can be spooled with the wooden applicator stick.
6.The colder the ethanol is the greater the amount of DNA that is precipitated. (You could try having some of the students use room temperature ethanol and see if the amount of DNA they can spool is the same or less than that for the groups using the ice-cold ethanol.
7.The reason is every strawberry seed contains different genetic material, the product of a myriad of potential gene combinations. Because the genetics of strawberries are so diverse (humans are diploid, strawberries are octoploid)
