Cystic Fibrosis is a homzygous recessive disease that affects 1 in 3400 people. What percent of the population are carriers?
Answer:
The correct answer is = 0.02 or 2.5 percent approx.
Explanation:
Given:
CF is a recessive disease that affects 1 in 3400 people
The frequency of the recessive allele in the population (q2) -
= 1/3400
= 0.0002. Therefore, q is the square root, or 0.014.
The frequency of the dominant allele in the population (p)
= 1 - 0.014 = 0.986 (or 98.6%).
The percentage of s carriers in the population.
2pq equals the frequency of heterozygotes or carriers, then the equation will be as follows:
2pq = (2)(.986)(.014) = 0.02 or 2.5 percent approx.

Identify the most efficient way to protect biodiversity.
Explain your reasoning.
**please do not put the sample response :) **
Protecting habitats before they are torn down.
or
we can consume less and be more mindful about what we consume.
The efficient way to protect biodiversity is to protect plant and animal species that are extinct day by day and minimize the effect of pollution on the environment.
What is biodiversity?Biodiversity is the diverse living things and nonliving things present on the earth. Biodiversity refers to the different species of plants and animals that live and interact with each other, and they are also dependent on each other.
Nature is interdependent, every organism depends on another organism for its living and the dance of the autotrophs gives energy to animals.
It is important to protect biodiversity because if animals and plants while extinct other animals can as also be living.
Thus, the most effective strategy to preserve biodiversity is to safeguard the rapidly disappearing plant and animal species while reducing environmental degradation.

4. Do you think that increasing the number and kinds of observations you make about something would affect any inferences you make about those observations? Why or why not?
Answer: The number of observations (sample size) is important in determining the reliability of statistical inferences. The kind of observations depends on what hypothesis is being tested. Different statistical techniques are required depending on whether the data is categorical or discrete or continuous and whether observations are quantitative or qualitative. Increasing the kinds of observations (multiple sets of data) may also add to the reliability of the test of the hypothesis.
Explanation:
In general, a larger sample size improves the reliability of any statistical inference, particularly when there is more variability (higher variance) in the data and when the expected effect is small. A larger sample reduces the chance of random error.
Where more than one variable is associated with output data, it is of course necessary to collect data of different kinds. For example, if your hypothesis is:
H: y = ax1 + bx2 + cx3 + ...........
then you need to have observations of x1, x2, x3.........

Answer:
Circadian rhythm
Explanation:
Circadian rhythm is a natural, internal process that regulates the sleep-wake cycle. It repeats that cycle on each rotation of the Earth every 24 hours. It has been said that if your circadian rhythm is out of weight can cause weight gains, impulsivity, slower thinking, and other behavioral changes it is similar to those who experience jet lags and work shifts.

A controlled experiment _____. Group of answer choices Includes at least two groups, one of which does not receive the experimental treatment Is repeated many times to ensure that the results are accurate Proceeds at a slow pace to guarantee that the scientist can carefully observe all reactions and process all experimental data Includes at least two groups, one differing from the other by two or more variables
Answer:
A. Includes at least two groups, one of which does not receive the experimental treatment
Explanation:
A control experiment can be defined as an experiment in which a condition assumed to be a probable cause of the effect is being compared to the same situation by the scientist without involving or using the suspected condition.
Also, an experimental group can be defined as a collection of participants that are subjected to the independent variable.
Generally, most scientific experiments usually have a control group so as to avail the scientists (experimentalists) an ability to compare the outcome of their test results. This control group is not given the treatment or influenced by the same independent variable as the experimental group.
Therefore, this is the reason why science completely or totally rejects any hypothesis which is not supported by observations, as well as the results obtained from control experiments.
This ultimately implies that, for any hypothesis to be acceptable in science, it must be supported by observations and the results of control experiments; this give rise to factual informations, theories and by extension solutions to problems.
Hence, a controlled experiment includes at least two groups, one of which does not receive the experimental treatment.
A controlled experiment includes a control group and at least one experimental group. Option A). A controlled experiment includes at least two groups, one of which does not receive the experimental treatment.
In a controlled experiment, the researcher wants to identify the effect of one or more variables on something.
Since many different variables might be affecting the results, and most of them are not of interest to the researcher, they must be kept under control. They must remain constant.
There must be at least two groups. One of them must be the control group, and the other one (or other ones) is the experimental group.
During an experiment, the researcher compares the two groups. Both of them are composed of individuals coming from the same population, so they are identical in all aspects except for the independent variables that the researcher changes in the experimental group to observe how they affect the individuals.
The control group is used to identify any other factors influencing the results obtained in the study, apart from the modified variables of the treatment. The independent variable keeps constant in the control group. The experimental group receives the treatment. The researcher voluntarily changes the values of the independent variable to observe how it affects the individuals subjected. There can be several experimental groups.
Hence, A controlled experiment includes at least two groups, one of which does not receive the experimental treatment.

If an element Has 35 protons and 36 electrons is it called an cation or anion
Answer:
In a neutral atom the number of protons = the number of electrons. 35 protons = 35 electrons. But Bromine anion with a charge of -1 has one extra electron so 35 +1 = 36 electrons. 36 electrons is the number of electrons in the stable inert gas Krypton. ... Protons + neutrons = Mass putting in known values.

A particular protein has the amino acid sequence: . . . Ala-Pro-His-Trp-Arg-Lys-Gly-Val-Thr . . within its primary structure. A geneticist studying mutations affecting this protein discovered a mutant that produced a shortened protein molecule that terminated within this region. In this mutant protein, the His became the last amino acid. What DNA single-base change(s) would cause the protein to terminate at the His residue
Answer:
The correct answer is - nonsense mutation.
Explanation:
The given amino acid sequence Ala-Pro-His-Trp-Arg-Lys-Gly-Val-Thr of a particular protein is affected by a mutation that leads to the shortened protein that ends in this region only. As we know the His amino acid becomes the last amino acid so in such case is it takes place due to nonsense mutation that is the only mutation or change result to terminate before or at the His codon.
The Trp codon which is coded by UGG codon could have been changed to either a UAG or a UGA codon in this case.
The correct answer is - nonsense mutation.
