Explanation:
An international research effort called the Human Genome Project, which worked to determine the sequence of the human genome and identify the genes that it contains, estimated that humans have between 20,000 and 25,000 genes. Every person has two copies of each gene, one inherited from each parent.
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]
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.
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.

What are the two factors that determine the boundaries of a biome?
altitude
temperature
precipitation
latitude
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.

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.

What process is occurring in this picture at B?
Answer:
Translation
Explanation:
Translation is the second process that occurs in protein synthesis. It is the process whereby mRNA template is used to synthesize an amino acid sequence, which eventually becomes a protein.
The process of translation occurs in the cytoplasm (specifically in the ribosome). As depicted in this image, the mRNA produced during transcription is transported out of the nucleus into the cytoplasm. A RNA molecule called tRNA reads the mRNA sequence (codon by codon) and carries corresponding amino acid into the growing amino acid sequence.
Hence, according to this question, the process occuring at B according to this image is TRANSLATION.

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
