A man and a woman are preparing to have a child. The man finds out that his father has
Huntington's disease. Huntington's disease is an autosomal dominant disorder. The man's
mother does not have Huntington's disease. The man has a sister who does not have
Huntington's disease.
a. Create a pedigree for the family describe. (Be sure to shade individuals affected with
Huntington's disease).
b. List the genotypes on your pedigree.
c. What is the probability that the male has Huntington's disease?
d. If the man has Huntington's disease what is the chance he will pass the disorder to his
child? The mother of the child is unaffected.
Answers
Answer:
Man´s father → Huntington's disease → DdMan´s mother → Normal → ddMan´s sister → Normal → dd The mother of the child is unaffected → ddMan → Dd → If affected → 50% or 1/2 of probability Man → dd → If not affected Child → Dd → If affected → 50% or 1/2 of probability Child → dd → If not affectedExplanation:
Huntington´s disease is Autosomal and Dominant, which means that by getting only one copy of the altered gene coming from any of the parents, the receiving person will express the disease.
Let us name the dominant allele D and the recessive allele d.
DD or Dd genotypes express the diseasedd genotype expresses the normal phenotype.Man´s father → Huntington's disease → Dd
Man´s mother → Normal → dd
Man´s sister → Normal → dd
The mother of the child is unaffected → dd
If the sister is normal, dd, means that the father is heterozygous for the trait. The sister inherited a recessive allele from her mother and the other recessive allele must have been inherited from the father, who expresses the disease.
The man has 1/2 of the chances of having the dominant allele because his mother could only pass a recessive allele (100%), and his father could pass either a recessive (50%) or a dominant allele (50%).
If the man inherited the dominant allele from his father, he is heterozygous for the trait, and he has 1/2 of the probability of providing a D allele to the child. The man´s wife is normal, dd, so she can only provide a recessive allele to the child.
Pedigree:
When drawing a pedigree, remember the symbols you need to use
Circles represent femalesSquares represent malesRhombus represents not specified sex (unborn)Full-shaded figures represent affected individualsEmpty figures represent unaffected individuals. Generations are represented with roman numbersIndividuals can be represented with numbers, genotypes, or namesYou will find the pedigree in the attached files

e. Stimulates an increase in the number of osteoclasts
f. Secreted when blood calcium levels are too low
g. Secreted by the thyroid gland
1. Calcitonin
2. PTH
Answers
Answer:
a. Calcitonin
b. Calcitonin
c. PTH
d. PTH
e. PTH
f. PTH
g. Calcitonin
Explanation:
Calcitonin is a short peptidic hormone secreted by the parafollicular cells of the thyroid gland. Conversely to the parathyroid hormone (PTH), calcitonin reduces the calcium level in the blood. If the calcium concentration in blood decreases, the concentration of calcitonin secreted decreases too. On the other hand, the PTH peptide hormone is an important hormone secreted by the parathyroid glands that affect bones and tissues. PTH stimulates the proliferation and activity of the osteoclast (specialized cells that play a crucial role in bone resorption) in order to increase calcium levels in the blood. PTH stimulates the expression of the receptor activator of nuclear factor-kappa-Β ligand (RANKL) protein, thereby activating osteoclast differentiation and inhibiting osteoclast apoptosis.

(c) Predict the growth rate pattern of the E. coli-M bacteria when they are initially added to the growth medium if the mutation does not interfere with glucose utilization.
(d) Provide reasoning to justify your prediction.
Answers
The question is incomplete. The complete question is :
Glucose is the preferred carbon source for Escherichia coli bacteria. Researchers isolated E. coli-M, a strain of E. coli with a single mutation that inactivates a key enzyme in one of the three glycolytic pathways E. coli bacteria use to break down glucose. In an initial experiment to study the effect of the mutation on glucose utilization and ATP production by the bacteria, the researchers add 2×104 E. coli-M bacteria to 400 mL of a growth medium that contains glucose. To measure the rate of bacterial growth, they monitor the optical density of the culture as a measure of bacterial concentration over time.
(c) Predict the growth rate pattern of the E. coli-M bacteria when they are initially added to the growth medium if the mutation does not interfere with glucose utilization.
(d) Provide reasoning to justify your prediction.
Solution :
c). It is given that Glucose is preferred as the carbon source for the Escherichia coli bacteria or the E. coli-M bacteria. If the growth medium of the E. coli-M bacteria contains a higher concentration of the acetate, then the growth of the bacteria will inhibit without inhibiting the central metabolism.
d). This is predicted because as E. coli-M bacteria grows, it starts secreting acetate. This is known as overflow mechanism. The regulatory interactions mediated by the acetyl-phosphate that plays an important role in the inhibiting growth by the acetate.

Many scientists claim that the facts support the belief that climate change is really happening. By examining scientific research and evidence, you will better understand issues and cut through the myths. As you read in the unit, it is important to carefully consider evidence because there is a lot of information in the public sphere that looks like science but it is not based on the scientific method. For this activity, you are going to do your own research on global warming and sort out the facts for yourself. Do research online to find evidence about global warming. To find reliable information, be sure that you use reliable websites, such as those from government organizations (.gov) or universities (.edu). You can also look at publications that are reputable, such as Popular Science, Discover, or National Geographic. Find a minimum of three sources that provide evidence about global warming.
Answers
Climate change is strong evidence of global warming. The data maintained by the concerned departments shows that as the graph of global warming rose, adverse changes in the climate occurred.
Therefore, an increase in global warming and change in climate is directly related. The increase in the speed of the melting iceberg can be seen as the temperature or global warming has increased.
What are the effects of climate change?Climate is a very important factor in the lives of all living organisms, because it is one of the major factors that determine if a living organism is going to survive or not.
Climate change is said to occur when there are changes in the earth's climate system, which result in the formation of new weather patterns that last for a long time.
Climate change affects living organisms in different ways; while climate change is beneficial to some organisms, it is detrimental to some. For instance, in Europe, climate change (increase in temperature) has been found to have positive effects on some bird populations.
Thus, this could be the answer.

4) plutonic
Explain how it formed. Thank you.
Answers
Answer:
1) sedimentary
Explanation:
Sedimentary rocks are formed by the accumulation and subsequent compression of sediments (i.e., minerals and once-living organisms known as fossils) on the Earth's surface. Almost all fossils are found within sedimentary rocks. Some examples of sedimentary rock that contain fossils include limestone, mudstone and shale. Rock layers are known as strata. The oldest layers containing the once-living organisms (which were fossilized as they formed) are found at the bottom, while the youngest layers are found at the top.

If a rat required a high rate of insulin infusion to maintain a specific blood glucose level, then you could conclude that it is:_______
Answers
Answer:
The correct answer is: diabetic.
Explanation:
There are several species where diabetes can manifest, like rats, dogs, and humans. Diabetes Mellitus is a condition characterized by hyperglycemia (high blood sugar levels) and can lead to many complications that are life-threatening to the patients. This hyperglycemia can be caused by a variety of reasons, but they all include an insufficient reach of insulin (the most important hormone in blood sugar regulation) to the target organs - sometimes this occurs because the pancreas can't produce insulin, other times it's because the organs cannot receive it.
In patients in which insulin is NOT produced by the body, the administration of exogenous insulin is required for their survival - this seems to be the case with the rat mentioned in the case. This rat is an insulin-dependent diabetic.

There is a claim that lycopene, the reddish substance in tomatoes and peppers, is of value in protecting people from Alzheimer Disease, a neurological condition. How would you, as a Biomedical Research Scientist, go about to refute or substantiate this suggestion?
Answers
Answer:
Conduct a study to determine if lycopene obtained from tomato and pepper consumption is significantly associated with a decreased level of abnormally folded proteins in neurons of the cerebral cortex
Explanation:
Alzheimer's disease is an irreversible, progressive, brain disorder characterized by the loss of neurons (the main brain cells) and synaptic connections in the cerebral cortex and specific subcortical regions. It has been shown that Alzheimer's disease is associated with an abnormal folding of proteins such as amyloid and tau proteins in neurons, thereby leading to the loss of communication between brain cells. In consequence, in this case, it should be interesting to design a study in order to observe if lycopene obtained from tomato and pepper consumption can decrease the levels of abnormally folded proteins in neurons of the cerebral cortex, which is a pathologic hallmark of Alzheimer's disease. For this purpose, it is expected to form two groups of study: 1-one group composed of individuals that regularly consume tomatoes and peppers and 2-one group composed of individuals that do not consume these fruits, as well as a third 'control' group composed of individuals that obtain lycopene by consuming other plants (e.g., watermelon, pink grapefruit and redd carrots which are also high in lycopene). Subsequently, it should be necessary to experimentally determine if lycopene is significatively associated with a decreased level of abnormal amyloid and tau proteins in neurons of the cerebral cortex. Finally, the comparison between individuals that regularly consume tomatoes and peppers with the control group may result useful to determine if different lycopene sources may affect protein folding.

Answers
to be more resistant to that antibiotic
if an antibiotic eliminates 99.9% of the germs. It makes sense to assume that the new strain of bacteria will be more resistant to that drug than the old strain. Here the correct option is A.
The majority of the susceptible bacteria in the population are killed by the addition of a bactericidal antibiotic, while the resistant bacteria continue to exist. Only the resistant bacteria will continue to grow and multiply while being exposed to the antibiotic.
Antibiotic misuse, overuse, and ineffective infection prevention and control all contribute to the acceleration of antibiotic resistance. At all societal levels, actions can be made to lessen the effects and contain the spread of resistance.
Thus the correct opion is A.
