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.

Why are antibiotics ineffective against viruses?
Answer:
antibiotics are useless against viral infections this is because viruses are so simple that they use their host cells to perform their activities for them. so antiviral drugs work differently to antibiotics by interfering with the viral enzymes instead
What are some possible sources for early organic molecules?
Answer: I hope this is the right answer you were looking for, if not I'm sorry
Explanation:
The first organic molecules formed about 4 billion years ago. This may have happened when lightning sparked chemical reactions in Earth's early atmosphere. RNA may have been the first organic molecule to form as well as the basis of early life.

Name one way the male and female endocrine systems are different.
Answer:
Men produce more testoterone and women produce more estrogen.
Explanation:
While both men and women produce testoterone and estrogen, men have higher concentrations of testoterone and women have higher concentrations of estrogen.
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

a. the existence of an inexpensive, effective vaccine
b. the removal of animal reservoirs in nature
c. rapid diagnosis due to obvious signs and symptoms
d. the fact that there are no asymptomatic carriers, so the disease is always diagnosable

Explanation:
The signs used depend on the species being surveyed and include the presence of runways and tracks on *
1 point
(a). soft substrates
(b) hard substrate
(c) dry mud
(d) rocks
Answer:
(a). soft substrates
Explanation:
Mobile organisms can be measured by both direct and indirect methods. Direct methods may involve observing the actual behavior (e.g., scoring via timing). Moreover, indirect methods are those where the technique used depends on the species being examined, collecting information such as through recording of tracks in the soft substrate (e.g., mud, sand, snow), presence of fur/feathers, droppings (mammals), etc. For example, indirect observation of insects may involve the determination of exoskeletons, sounds, etc.
