The word root infect means which of the following?
Answer:
late 14c., "fill with disease, render pestilential; pollute, contaminate; to corrupt morally," from Latin infectus, past participle of inficere "to stain, tinge, dye," also "to corrupt, stain, spoil," literally "to put in to, dip into," from in- "in" (from PIE root *en "in") + facere "to make, do, perform" (from PIE root *dhe- "to set, put").
Explanation:
A prospective groom, who is healthy, has a sister with cystic fibrosis (CF), an autosomal recessive disease. Their parents are normal. The brother plans to marry a woman who has no history of CF in her family. What is the probability that they will produce a CF child? 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:
Explanation:
From the given information:
Since the parent are normal; Let assume that their trait is Pp
The affected sister will be recessive in nature, so the trait will be pp
Now, the husband who is the groom will be a carrier with a probability of 2/3 since her sister is affected.
Also, the wife will be carrying a heterozygous trait since she is normal as well.
However, using Hardy-Weinberg assumption:
[tex]q^2 = \dfrac{1}{2500}= 0.0004[/tex]
[tex]q = \sqrt{0.0004}[/tex]
q = 0.02
Recall that:
[tex]p+q =1 \\ p = 1 - q \\p = 1 - 0.02 \\p = 0.98\\[/tex]
Thus, [tex]p^2 = (0.98)^2[/tex]
[tex]p^2 = 0.9604[/tex]
[tex]2pq = 2 \times 0.98 \times 0.022[/tex]
2pq = 0.0392
Finally, the required probability that there will be an affected offspring amongst the family is:
[tex]= \dfrac{1}{4} \times \dfrac{2}{3} \times 0.0392[/tex]
[tex]= \dfrac{1}{153}[/tex]

Choose one of the following scenarios and answer the questions provided. Support your answers using scientific reasoning and discussing possible impacts to individuals, society, and the environment. Be sure to also discuss any medical or ethical issues that may apply. (10 points)
Scenario 1:
Genetic engineering can be used to create more productive strains of farm animals. By adding genes to an animal's DNA, the animal can be made to produce milk or meat containing vital nutrients that would not be found naturally in those products. This provides a greater amount of nutrients per serving of milk or meat.
Do you think that this type of genetic engineering should be pursued? Explain your answer. (5 points)
What are some possible impacts (positive and negative) of this type of genetic engineering on individuals, society, and the environment? (5 points)
Scenario 2:
In the future, doctors may be able to evaluate your DNA to check for genetic markers related to specific medical conditions or harmful reactions to medications. Your personalized genetic profile could be kept on record and referred to in order to develop personal medical treatment based on your unique DNA sequencing. Scientists have found that just small variations in a specific section of your DNA can help determine how well some medications can work for you or if they would be beneficial at all.
Would you want to have your DNA profile kept in your medical record as a reference for your doctors? Explain your answer. (2 points)
What are potential pros and cons of having such tests done and referring to DNA sequences when determining a patient's medical treatment? (5 points)
Describe how the availability of this technology might affect the frequency of genetic diseases in individuals and populations. (3 points)
Answer:
i tried my best (so many questions on scenario 2)
Explanation:
scenario 1: there are many positive and negative possible impacts that come with genetic engineering. A very negative outcome could come from just one mistake. But if there was a way to ensure that nothing could go wrong than the outcome would be an healthy new meat or milk that's packed with nutrients.
scenario 2: I think if this was a real thing i would be completely for it. If a person was to get their DNA checked then doctors would be able to prescribe a medication that would fit you. this could also prevent any allergic reactions to and medications or treatments.
I personally would want my DNA profile kept on record so that i can be treated with the right medications for me.
(The potential list pros and cons would probally look like this)

1. Predict: How do you expect the spread of a foodborne disease to be similar to and different
from the spread of a person-to-person disease?
PLEASE ANSWER
Answer and Explanation:
The transmission of diseases through food and through people to people, are similar because both are caused by human contact with infectious parasitic agents such as bacteria and viruses. However, it is possible to notice some differences between these two types of transmissions.
Transmission of disease through food occurs when an individual eats contaminated food or drinks contaminated liquid. This contamination occurs due to the lack of hygiene of the handlers and storage problems, which can allow microorganisms, mostly bacteria, to grow in the food. Thus, when the contaminated food is ingested, the microorganisms will release toxins in the stomach that will cause disease. In the case of water, contamination can also happen due to the lack of basic sanitation and the incorrect dumping of garbage and human waste.
Diseases transmitted from person to person can occur in many different ways. One of the best known ways is through the contact of a healthy person with salivary goths or other body fluids of a person with the disease. However, this transmission can also occur through the contact of a healthy individual with the feces of a sick individual and even with physical contact with a sick individual.

Answer:
A. altitude
and
D. latitude
Explanation:
hope this helps! :D
The two factors that determine the boundaries of a biome are temperature and precipitation, which are the second and third options, as they help to shape the unique features of each biome.
What is the significance of the precipitation and temperature?Temperature plays a key role in determining the type of vegetation, such as in colder regions where low temperatures limit the types of plants that can grow, while in warmer regions the growth of tropical rainforests is seen. Precipitation plays an important role too, as in areas with high levels of precipitation, such as tropical rainforests, dense vegetation is seen, and in dry regions with low levels of precipitation, deserts are seen.
Hence, the two factors that determine the boundaries of a biome are temperature and precipitation, which are the second and third options, as they help to shape the unique features of each biome.

Answer:
Explanation:
An ecosystem engineer can cause a cascade of effects including abiotic and biotic changes.
O True
False
Answer:
O True
Explanation:
Ecosystem engineers are able to modify the surrounding environment, either by creating new habitats or modifying/destroying existing ones to adjust them to their needs. These species can significantly alter their environments, having a large impact on the species richness as well as modifying the availability of abiotic factors (e.g., water, space, etc) of a particular area. In certain environments, ecosystem engineers can even act as keystone species. Some examples of ecosystem engineers include, among others, beavers, woodpeckers, corals, etc.
how does the envirment select organisms
Answer:
The environment "selects" organisms that are better adapted to their environment and thus have a better chance to survive and reproduce. ... Helpful variations accumulate through natural selection, as the organisms that are better adapted to their environment reproduce offspring with the same variations.

14. Kidneys are filters. As blood passes through the kidney, waste in the form of urine is
left behind. Tubes take the urine from the kidney to a storage bag called the bladder.
What can you conclude about blood leaving the kidney?
A. It moves to the bladder.
B. It has no water left in it.
C. It is ready to be used by the body.
D. It needs to have urine added to it
Answer:
D. It needs to have urine in it
Explanation:
They are located just below the rib cage, one on each side of your spine. Healthy kidneys filter about a half cup of blood every minute, removing wastes and extra water to make urine. The urine flows from the kidneys to the bladder through two thin tubes of muscle called ureters, one on each side of your bladder. The fluid that is filtered out from the blood then travels down a tiny tube-like structure called a tubule. The tubule adjusts the level of salts, water, and wastes that will leave the body in the urine. Filtered blood leaves the kidney through the renal vein and flows back to the heart.

How many grams of water can be heated from 20.0 oC to 75oC using 12500.0 Joules? The specific heat of water = 4.186 joule/gram °C
Answer:
The correct answer is - 0.054 kg
Explanation:
Given:
change in temperature: 55°C
Heat energy = 12500 J
specific heat = 4.186
Formula:
The formula for Heat Energy is given by:
Q = mcp∆T
here: Q - Heat Energy
m is for mass
cp is for specific heat
∆T is a change in temperature,
Solution:
From formula,
m = Q/ cΔT
Mass = 12500 / (55 × 4200)
= 0.054 kg or 54 g
