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.
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

Some blackcaps that migrate to the United Kingdom have become distinguishable by certain physical and behavioral traits from blackcaps that migrate to Spain. What best predicts the effect on the blackcap population if humans in the United Kingdom continue to place food in feeders during the winter?
Answer:
Increases.
Explanation:
There is a good effect on the blackcap population if humans in the United Kingdom continue to place food in feeders during the winter because there is more food available for the blackcap bird which automatically increase the population of the bird. Food is the main factor that contributes in the increase or decrease population of blackcap in the United Kingdom and prevent the removal of this bird in that environment.

Answer:
I'm assuming yellow is dominant since they used Y
YY and Yy are both yellow
yy is blue
So Yellow color would have 75% phenotype probability and Blue would have 25%
The enzyme could become spatially distorted, thus reducing the ability of the active site to catalyze the reaction. Tight enzyme-substrate binding will reduce the forward rate constant for the reaction. Tight binding of the enzyme to its substrate will pull the substrate out of solution, thus decreasing the driving force for the forward reaction. Tight binding of the enzyme to its substrate will result in the enzyme-transition state complex being higher in energy than with weaker binding. All of the above.
Answer:
All of the above.
Explanation:
All the given options are the potential disadvantage of an enzyme that have a very high affinity for its substrate.
The enzyme can be distorted spatially and thus reduces the ability to catalyze the reaction of the active site.
The tight binding of an enzyme to a substrate results in enzyme transition state complex which is higher in energy.
The tight binding also pulls the substrate out of the solution and decreases a driving force in the forward reaction.

A macaw is a type of parrot with colorful feathers that flies about in the upper canopy of trees in tropical rainforests. Macaws have a diet which includes
fruits, leaves, nuts, and seeds of plants. Which of the following describes a biotic factor of the macaw's habitat that provides a survival advantage for
these birds?
o
The colorful feathers are lost and regrow each year
0
Some rainforest predators are able to climb trees
o
Trees provide shelter and a macaw
Answer:
Trees provide shelter
Explanation:
Firstly, a biotic factor refers to the living component of an ecosystem including the plants, animals and microbial species of one another. According to this question, a macaw is a type of parrot with colorful feathers that flies about in the upper canopy of trees in tropical rainforests. Macaws have a diet which includes fruits, leaves, nuts, and seeds of plants.
In order to ascertain that this birds species are in survival advantage, trees, which is one of the biotic factors found in the tropical rainforest, provide shelter for these birds.
What are the scientists doing incorrectly? What could they do to make their work in the lab safer? Why is it important to follow these procedures? Part A
Answer:
Part A
The scientists threw away their instructions. They should have kept their instructions to properly and safely follow all procedures. Following instructions also ensures useful experimental results.
Part B
The scientist is not wearing safety goggles. He should wear goggles during activities that can harm his eyes. Working safely to avoid injury is every scientist’s job.
Part C
The lab area is messy and needs better organization. The scientist should carefully store the test tubes that aren’t being used. A clean work area helps scientists work safely and efficiently to avoid costly accidents.
Part D
The scientist is disposing of dangerous materials incorrectly. He should have followed disposal instructions as described in the lab procedure. Improper disposal can pollute the environment, harm fragile wildlife, and damage facilities. Scientists must be environmentally responsible.
Part E
The scientist didn’t clean up after an accident. He should have disposed of the glass immediately after it broke rather than waiting. Accidents create hazards for scientists and those around them.
Part F
Scientists should not eat or drink in a lab area. They could swallow something harmful or foul. Snacks and meals should be eaten during designated breaks and never near the lab area.
