Cystic fibrosis is most common in individuals of Northern European descent, affecting 1 in 3200 newborns. Assuming that these alleles are at Hardy-Weinberg equilibrium, what is the frequency of the disease-causing CFTR alleles in this population
Answers
Answer:
0.0177
Explanation:
Cystic fibrosis is an autosomal recessive disease, thereby an individual must have both copies of the CFTR mutant alleles to have this disease. The Hardy-Weinberg equilibrium states that p² + 2pq + q² = 1, where p² represents the frequency of the homo-zygous dominant genotype (normal phenotype), q² represents the frequency of the homo-zygous recessive genotype (cystic fibrosis phenotype), and 2pq represents the frequency of the heterozygous genotype (individuals that carry one copy of the CFTR mutant allele). Moreover, under Hardy-Weinberg equilibrium, the sum of the dominant 'p' allele frequency and the recessive 'q' allele frequency is equal to 1. In this case, we can observe that the frequency of the homo-zygous recessive condition for cystic fibrosis (q²) is 1/3200. In consequence, the frequency of the recessive allele for cystic fibrosis can be calculated as follows:
1/3200 = q² (have two CFTR mutant alleles) >>
q = √ (1/3200) = 1/56.57 >>
- Frequency of the CFTR allele q = 1/56.57 = 0.0177
- Frequency of the dominant 'normal' allele p = 1 - q = 1 - 0.0177 = 0.9823

Answer:
14. (a) Pb
15. (d) Al
16. (A) increases
Explanation:
14.
In the reactivity series of metals an element can displace another element from a compound if and only if it is not placed below that metal, as the reactivity of metals decreases when moving from top to bottom- if a metal is placed below Hydrogen it means that it is less reactive than Hydrogen and hence cannot displace Hydrogen from its compound.
All options except A are placed below Hydrogen in the reactivity series, so they wont displace Hydrogen from its compound, but option (a) that is Pb can do so as it is above Hydrogen in the reactivity series.
15.
Al is placed below Mg in the reactivity series and hence cannot displace Mg from its compound.
16.
The reactivity of metals increases down the GROUP.
[CAUTION :- We were talking 'bout REACTIVITY SERIES in the top 2 questions where reactivity decreases down the group, but we're talkin' 'bout GROUPS of the periodic table here, where reactivity increases down the group.]
The size of metals increases down the group causing their valence electrons to drift far from the nucleus so that they can be lost easily. The metals have a property of losing electrons so the more electrons it can lose more will be its reactivity.
Hence, reactivity increases down the group.
Post Lab Report Part II 6. The probability that the two offspring you produced share every genotype in common is extremely low. Explain why they are likely to be different. 7. How would genetic variability be affected if more chromosome pairs were added? What about if another partner was added?
Answers
Answer:
Explanation:
Answer to 6:
The probability of two offspring with the same genotype is very low because due to recombination between the chromosomes of the father and mother each gamete has a different composition of genetic material. The only chance that they share the genotype is if they were zygotical twins.
Answer to question 7:
When you increase the number of chromosomes the variability will increase too.
Which of the following statements depend on the absolute dating of events?
Answers
Answer:
The statement that depends on the absolute dating of events is this: The oldest Earth rocks are 3.9 billion years old. Absolute dating is the method of determining the specific date of an archaeological or paleontological artifact.
Answer:
It says that the oldest Earth rocks are 3.9 trillion years old, and they depend on the absolute adaptations of events. Absolute dating is the mechanism through which an archaeological or paleontological artifact determines a particular date.
120 million years ago, birds diverged from the related dinosaurs.3.9 billion years old is the oldest Earth rock.Explanation:
Geologists must often know the material age they encounter. They use absolute data systems, sometimes referred to as numerical dates, to provide rocks with the actual date or date range for years to come. It differs from relative dates, which only time-consuming geologic events.
In contrast to the relative date, the absolute date represents a certain age or range which places occurrences among events without age being measured. The most absolute ages for rocks are reached by radiometric methods. Minerals are radioactive in rocks like geological watches.

The following statement is incorrect as stated "Pesticides create pesticide resistance in mosquitoes." Rewrite this sentence so that it is a more accurate statement of what actually occurs when pesticides are used. Why is this concept important to know in trying to control outbreaks of mosquito transmitted diseases such as eastern equine encephalitis (also known as Triple E)?
Answers
Answer:
Mosquitoes usually become resistant to pyrethroids through the mutation of a sodium channel gene that controls the movement of ions across cell membranes. Mutations in a single gene are enough to make mosquitoes almost completely resistant to the level of pyrethroids used in insecticides.
different evolution theory of living organism
Answers
Answer:
(I) Lamarckism or Theory of Inheritance of Acquired characters.
This theory is based on the comparison between the contemporary species of Jean Baptiste de Lamarck's time to fossil records.
(II) Darwinism or Theory of Natural Selection.
Charles Darwin made an extensive study of nature for over 20 years, especially in 1831-1836 when he went on a voyage on the famous ship “H.M.S. Beagle” and explored South America, the Galapagos Islands and other islands.
(III) Mutation theory of De Vries.
The mutation theory of evolution was proposed by a Dutch botanist, Hugo de Vries (1848-1935 A.D.) in 1901 A.D. in his book entitled “Species and Varieties, Their Origin by Mutation”. He worked on evening primrose (Oenothera lamarckiana).
(IV) Neo-Darwinism or Modern concept or Synthetic theory of evolution.
The detailed studies of Lamarckism, Darwinism and Mutation theory of evolution showed that no single theory is fully satisfactory. Neo-Darwinism is a modified version of theory of Natural Selection and is a sort of reconciliation between Darwin’s and de Vries theories.

Would an observational study or an experiment be more appropriate to investigate the effects on fertilizer on plant growth? Explain.
Answers
Answer:
Experiment
Explanation:
For such an investigation an Experiment would be the better option. This is because in an experiment you would have both an experimental group and a control group. This would allow you to use fertilizer on one but not the other, therefore, providing seperate results that you can use to compare with one another. This ultimately helps you determine the actual effects that fertilizer has on the growth of plants, since the fertilizer would be the only variable in the experiment. An observational study would only allow you to observe the plants in a natural scenario, without interfering and seperating the plants into different groups with different environments.

Answers
Answer:
- When a neuron is stimulated and sodium channels open, the process of depolarization has begun.
- Structures of the nervous system surrounding, but not part of the central nervous system are part of the peripheral nervous system
- Two consecutive neurons communicate at a synapse, where they physically come together.
- Endorphins are a group of natural chemicals that reduce the perception of pain.
- Supporting cells of the nervous system are collectively called neuroglia
- When potassium channels have been open long enough to go below resting membrane potential, hyperpolarization has occurred.
Explanation:
Neurons undergo depolarization in response to diverse stimuli (e.g., heat, light, electrical, chemical, etc). The depolarization occurs when sodium (Na+) ions pass through specific channels (i.e., open voltage-gated Na+ channels) into a neuron, which causes an increase in the positivity of membrane potential. On the other hand, hyperpolarization occurs when potassium (K+) channels remain open and Na+ channels reset, thereby producing an increase in negativity of membrane potential. The peripheral nervous system (PNS) is composed of the cranial nerves, spinal nerves, peripheral nerves, and neuromuscular junctions, which connect the Central nervous system (CNS) to the organs, limbs, and skin. Endorphins (e.g., serotonin) are polypeptides secreted by the pituitary gland and CNS to relieve stress and pain. Neuroglia refers to a class of neural cells that have ectodermal (e.g., astroglia, peripheral glial cells) or mesodermal (e.g., microglia) origins. Neuroglia cells are involved in diverse roles, including, among others, the formation of the blood-brain barrier, homeostatic support, provision of nutrients for neurons, structural support to nerve cells, etc.

Explanation:
As illustrated in this question, Gregor Mendel used the color trait of pea plant to discover his law of dominance.
The results Mendel obtained during his experiments. It showed that if you cross two plants that were true breeding for different colors (purple and white), the offspring or first generation (F1) would be HETEROZYGOUS (Pp) instead of true-breeds, and all were PURPLE in color.
Interestingly, when he crossed two of these F1 plants (Pp × Pp), their offspring did not all come out PURPLE, instead he obtain a ratio of 3 purple-flowered plant for every 1 white-flowered plant. He concluded that the “heritable factor” for the RECESSIVE trait (white flowers) was not destroyed in the F1 generation. Instead it had been MASKED by the “heritable factor” of the DOMINANT trait (purple flowers).
There are six major groups of enzymes. The categories are based on the types of reactions that they catalyze. What type of enzyme can join together two molecules to make a larger molecule such as a long strand of DNA
Answers
Answer:
DNA ligase.
Explanation:
DNA ligase is a type of enzyme that is responsible for join together of two molecules to make a larger molecule such as a long strand of DNA. This enzyme joins the end of two DNA molecules making it a long strand of DNA. In DNA cloning process, restriction enzymes and DNA ligase enzymes are used to incorporate genes and other pieces of DNA into plasmids so we can say that DNA ligase is responsible for long strand of DNA.

Answers
Answer:
The true statements regarding the adrenal glands' relationship with the autonomic nervous system are:
a. The adrenal cortex is an extension of the parasympathetic nervous system.
c. The adrenal glands are strictly nerve tissue.
d. The parasympathetic division stimulates the adrenal cortex to secrete glucocorticoids.
e. The adrenal medulla is penetrated by the fibers of the sympathetic nervous system.
Explanation:
The levels of the central nervous system which play important roles in influencing the autonomic nervous system include cerebral cortex, hypothalamus, brain stem, and spinal cord. Usually, epinephrine (adrenaline) and norepinephrine are released into the blood stem when stress or a threat occurs. This alert serves as a warning signal and defense system. The purpose is to maintain homeostasis.
which fundamental units are involved in force do step Wise
Answers
Force = ma
We know, the unit that the S.I. unit of mass is Kg.
We also know that a = (v - u)/t.
We know that v = d/t and u = d/t and the S.I. unit of t(time) is s.
We know that the S.I. unit of d(displacement) is m.
So, the S.I. unit of v is m/s and the S.I. unit of u is m/s and the S.I. unit of t is s.
So, the S.I. unit of a is m/s×s or m/s²
So, the unit of force is
(unit of m) × (unit of a)
= kg × (m/s²)
= kg.m/s²
=
[tex]kg \: m \: {s}^{ - 2} [/tex]
Or more simply,
F = ma
=> F = m{(v-u)/t}
Putting units,
Newton = kg[{(m/s) - (m/s)}/s]
=> Newton = kg{(m/s)/s}
=> Newton = kg(m/s²)
=> Newton = kg.m/s²
=> Newton = kg.m.(s^-2)

RBCL denotes for 'rubisco protein.' It is characterized as 'a plant enzyme which catalyzes both the fixing of carbon dioxide found in atmosphere during photosynthesis and the reverse process of photorespiration.' It plays a very significant role in studying, as well as, in evaluating relations associated with phylogenetics in plants primarily along with green algae as it assists them to produce energy molecules by using carbon dioxide from the atmosphere. It has therefore been the key factor behind a number of organic carbon that is discovered in our surrounding biosphere.
