A prospective groom, who is not affected by cystic fibrosis (CF), has a sister with cystic fibrosis, an autosomal recessive disease. Their parents are also not affected. The brother plans to marry a woman who has no history of CF in her family. What is the probability that they will have a child with CF? They are both Caucasian and the overall frequency of CF in the Caucasian population is 1/2500 - that is, 1 affected child per 2500 (assume the population meets the Hardy-Weinberg assumptions).
Answer: In punnett square number 1, we see the cross between AA and aa, and the result is 100% Aa individuals, so there is 0% chances of haveing a child with CF. In punnett square number 2, we see the cross between Aa and aa and there is 50% chances of having a child with CF (aa genotype).

the amount of electrical energy that can be generated by a hydroelectric power plants depends upon
Answer:
The amount of electricity a hydropower plant produces depends on two factors: How Far the Water Falls. The farther the water falls, the more power it has. Generally, the distance that the water falls depends on the size of the dam.
Explanation:
The amount of electrical energy that can be generated by a hydroelectric power plant depends upon the following factors:
The actual flow rate of water. The height of the water that falls. What is a Hydroelectric power plant?A Hydroelectric power plant may be defined as a renewable source of energy that generates electricity through the utilization of water from dams or diversion structures. Such types of plants are mainly used to transform hydraulic potential energy into electrical energy from water.
The actual flow rate and height of the water from it is falling demonstrate the amount of generated electrical energy. If the amount of water is present in excess quantity with a huge rate of flow and more the height of water in the hydroelectric power plant, it reveals that the generated electricity must be high under such circumstances.
Therefore, the rate of flow and height of water overall reveals the amount of electrical energy that can be generated by a hydroelectric power plant.

Explain why conflict avoidance does not help in sustaining positive relationship
Answer:
Avoidance is not healthy for sustaining the positive relationships as the ignorance or avoidance can cause the damage between the relationships of the people. The maintenance of the relationship among people can be hampered by avoidance. It can make the other people feel neglected. That can cause a failed relationship.

CAN FISH SURVIVE ONLY IN WATER WITH DISSOLVED OXYGEN?
Answer:
Oxygen dissolves into water from two sources: the atmosphere and from plants in the water. kills fish from oxygen depletions can range from “partial” to “total”. In a partial kill the dissolved oxygen level gets low enough to suffocate sensitive species and large fish, but many small fish and hardy species survive.

A population of 1,000 healthy, at risk people is monitored for one year starting on January 1st, and the development of cases of chicken pox is noted. No one has chicken pox at the start of the investigation. Twenty people develop chicken pox on June 30th and forty people develop chicken pox on September 30th. Twenty-four people were lost to follow-up on March 31st, and twenty-four people were lost to follow-up on November 30th. None of those lost to follow-up had developed chicken pox prior to becoming lost. Assume that you can get chicken pox only once.
Required:
What is the cumulative incidence of chicken pox in this population during the one-year period from January 1st through December 31st?
Answer:
[tex]\mathbf{cummulative \ incidence = \dfrac{60}{1000}}[/tex]
Explanation:
We recognize that total occurrence equals new cases of disease over time divided by the number of people at risk at the onset.
Mathematically:
[tex]\mathbf{cummulative \ incidence = \dfrac{New \ cases \ of \ disease \ occurrence}{Number \ of \ population \ at \ risk \ at \ onset}}[/tex]
Given that:
Number of the population at risk = 1000 individuals
New cases during Jan 1 - Dec 31 = 60 because;
At 20 occurred on June 30 & 40 on Sept. 30) & no new cases were identified after that:
∴
[tex]\mathbf{cummulative \ incidence = \dfrac{60}{1000}}[/tex]
g It was noted in the Experimental Pathways feature in Section 10.4 that at least two- thirds of the human genome is derived from transposable elements. The actual number could be much higher, but it is impossible to make a determination about the origin of many other sequences. Why do you suppose it is difficult to make assignments about the origin of many of the sequences in the human genome
Answer:
TEs are repetitive and mobile elements, thereby it is hard to trace their origins
Explanation:
Repetitive elements are patterns of nucleotide sequences in the DNA characterized to have multiple copies throughout the genome. DNA mini-satellite and Transposable Elements (TEs) are some examples of highly repetitive DNA. TEs are repetitive mobile elements that have the ability to jump within the genome and occupy a major part of eukaryotic genomes. For instance, there is a type of TEs called retrotransposons which mobilize through a copy-and-paste mechanism, thus increasing their number in a genome. In consequence, TEs represent highly repetitive and dynamic genomic sequences, and thereby it is hard to trace their evolutionary histories.
Place these events in the correct order of occurrence in the muscle contraction: End plate potential triggers an action potential Transverse tubules convey action potentials into the interior of the muscle fiber Acetylcholine binds to receptors on the motor end plate Calcium is released from the sarcoplasmic reticulum Ligand-gated channels open leading to depolarization Calcium ions bind to troponin, which then moves tropomyosin
Answer:
1. Acetylcholine binds to receptors on the motor end plate
2. Ligand-gated channels open leading to depolarization
3. End plate potential triggers an action potential
4. Transverse tubules convey action potentials into the interior of the muscle fiber
5. Calcium is released from the sarcoplasmic reticulum
6. Calcium ions bind to troponin, which then moves tropomyosin
Explanation:
Acetylcholine (ACh) is a signaling molecule (neurotransmitter) that binds to receptors on muscle cells. This binding triggers the opening of ligand-gated sodium channels, thereby ions enter into muscle cells, which causes the depolarization of the sarcolemma and thus promotes the release of Ca2+ ions from the sarcoplasmic reticulum. The myoneural junction, also known as the motor endplate, is the site of synaptic contact between a motor axon and a skeletal muscle fiber. The endplate potential is the voltage that produces the depolarization of muscle fibers when ACh molecules bind to their receptors in the cell membrane. This depolarization spreads in the sarcolemma through transverse tubules (T tubules) and thus generates an action potential. Finally, this action potential induces the release of Ca2+ in the sarcoplasmic reticulum, which activates troponin protein and induces muscle contraction.

What is dispersion of light?Dispersion of light is the separation of white light onto its constituent color as it passes through a refraction prism.
White Light consists of seven colours of varying wavelength.
When light is passed through a refracting prisms, dues the difference in the speed of the different constituents of light, seven colours of light are produced.

You want to build a house in an area with a maximum amount of species diversity. For building the house you have to clear up to 3/4th of the forest cover. How do you think this will affect the water runoff?
Answer:
The runoff will increases.
Explanation:
The runoff will be adversely affected if the 3/4th of the forest cover is removed because forest cover lowers the intensity of runoff by absorbing most of the water. The construction of house will increase the runoff due to little vegetative cover for the absorption of water and more water will runoff on the surface that will leads to flood condition in the lower elevated region of that area. The vegetative cover of the forest helps in preventing the flood condition by absorbing the runoff water.
