rabies:
What are the symptoms the animal would exhibit?
How does the disease impact the animal?
How could you prevent exposure to this disease?
Answer:
Symptoms:
FeverHeadacheHydrophobiaPhotophobiaAgitation Increased salivationThe animal becomes hyperreactive to external stimuli and bite at anything nearIncoordination is seen due to rear limb paralysis and drooling and difficulty swallowing is caused by paralysis of facial and throat muscles.It's a deadly disease. Death is usually caused by respiratory arrest.
Prevention can be done through:
Vaccinating dogs, cats, and ferrets against rabiesKeeping pets under supervisionContacting an animal control officer if the animal is acting strangelyAntibodies are composed of two types of peptides, heavy chains and light chains. One of the major classes of antibody molecules is immunoglobulin G (IgG). Two heavy chains and two light chains form one IgG molecule. Classify each statement as describing the heavy chains, light chains, or both chains of IgG
a. form the antigen-binding site
b. contain multiple variable domains
c. are found in the Fab fragment
d. are found in the FC fragment
e. contain only one constant domain
f. contain multiple constant domains
g. contain only one variable domain
Answer and Explanation:
a. form the antigen-binding site ⇒ both chains
The antigen-binding site is formed by one hypervariable region of the light chain (VL) and one hypervariable region of the heavy chain (VH). So, both type of chains contributes to antigen recognition.
b. contain multiple variable domains ⇒ none
Both chains - light and heavy - contain only one variable domain (VL and VH).
c. are found in the Fab fragment ⇒ both chains
The Fab fragment is composed of portions of both light and heavy chains: each portion contains one variable domain and one constant domain. The Fab fragment binds specifically the antigen.
d. are found in the FC fragment ⇒ heavy chains
The Fc region is composed of portions of heavy chains (CH² and CH³), so it contains constant domains.
e. contain only one constant domain ⇒ light chains
Each light chain contains one variable domain (VL) and one constant domain (CL).
f. contain multiple constant domains ⇒ heavy chains
Each heavy chain contains three constant domains: CH¹, CH² and CH³.
g. contain only one variable domain ⇒ both chains
Both light and heavy chains contain one variable domain. The difference is given by the number of constant domains: light chains have 1 constant domain while heavy chains have 3 constant domains.

Explanation:
The California Mussel ( Mytilus californianus ) is the natural prey of the shore crab ( Carcinus maenas ). Study the graph above. Why would a crab adapt to having larger claws according to the graph?
a. Larger claws would help the crab camouflage in the rocks so the mussels won’t see them.
b. Larger claws would help the crab swim fast in a rough current toward where the mussels are hiding.
c. Larger claws would help the crab crack open the shells of the mussels so the crab can eat them.
d. Larger claws would scare away the mussels with thicker shells causing the crabs to choose a new food source.
Answer:
The correct answer is - c. Larger claws would help the crab crack open the shells of the mussels so the crab can eat them.
Explanation:
The graph (attached) states that the two variables size of claws of the crabs depends on the thickness of the shell of mussels. With the increase in the thickness of the shell of the mussels the size of the claws of crabs also increases and becomes larger.
The most likely explanation of this change would be adapting according to the change in the shell of the crab as they require to crack their shell to eat them as mussels are the primary food source of these crabs.

Many Learners Perform Well In Grade 12 But still not accepted into Universities.Explain Two Reasons For This
Answer:
1. Confusion
2. Financial issue
Explanation:
1. The reason I say this is that many of them are not really sure about what they want they want to do in their later future making them a little confused on what to do.
2. It is a common issue which has taken away so many bright minds away from their future in helping the world and their individual community to prosper in different ways.
The reason why many students from grade 12 are not accepted in universities is that they may not be ready to pursue a given career or their parents may not be able to afford it.
Why are grade 12 students not accepted in universities?In the whole of North America, grade 12 is the senior class or the highest class in high school.
Some grade 12 students may not be admitted into university even though they performed well because;
Some of the students who have finished well in grade 12 do not yet have clear cut career orientations.Also, some of them may not have parents that can afford to send them to the university.Hence, a good performance in grade 12 do not guarantee university admission.

In garden peas, tall (T) vine is dominant over short (t) vine, and round pea pod (R) is dominant over wrinkled pea pod (r). Cross an h0m0zygous tall, round pea plant with an h0m0zygous short, wrinkled pea plant. Show the genotypes and phenotypes of the F1 offspring and the probability of each.
__________ Genotype of the h0m0zygous tall, round pea plant
__________ Genotype of the h0m0zygous short, wrinkled pea plant.
Answer:
TtRr - 100%
Explanation:
This question involves two different genes in pea plants. One gene is coding for height and the other for pea shape. The allele for tallness (T) and round (R) pea is dominant over the allele for shortness (t) and wrinkled (r) peas.
According to this question, an h0m0zygous tall, round pea plant (TTRR) is crossed with an h0m0zygous short, wrinkled pea plant (ttrr). The following gametes will be produced by each parent:
TTRR - TR, TR, TR, TR
ttrr - tr, tr, tr, tr
Using these gametes in a punnet square (see attached image), the following proportion of offsprings is produced in the F1 generation: All or 100% TtRr
TtRr will be phenotypically tall and round.

Premed students are often traumatized by studying for their MCAT exam, which historically was always taken at the end of their Junior year in college. Now, many medical schools desire a meaningful gap year between completion of an undergrad degree and entrance to medical school so that incoming students have some sort of life-time experience either working, doing research, charity outreach, or traveling during that time. As a result, modern pre-med students often wait to study for their MCAT until after they graduate without realizing that it means they will end up taking two gap years, not one. Students who complete a basics genetic course should be confident with their knowledge about DNA, RNA, and proteins, along with how to solve basic inheritance problems, which will help them on their MCAT exams. Introductory Genetics helps to reinforce concepts taught fleetingly in Introductory Biology.
1. Jiro is told that a bacterium contains a single DNA chromosome containing 15% guanine and then is asked to decide if the organism is âGCâ rich or not (>50% G-C content = 'rich')). With full confidence, Jiro responds:
A.Heck no! The strand has a GC content of 30%.
B.Heck yeah! The strand has a GC content of 70%.
C.Heck no! The strand has a GC content of 15%.
D.It contains exactly 50% GC content.
2. If Marisol isolates 15% guanine from a strand of DNA, she can say with full confidence that:
A.the strand is made up of 70% pyrimidines.
B.the strand is made up of 30% pyrimidines.
C. the strand is made up of 50% pyrimidines and 50% purines.
D.the strand is made up of 70% purines.
3. Jayson is asked if a strand of DNA that is GC-rich will be harder to separate than one that is GC-poor. He responds with full confidence:
A. No!
B.Yes!
C. This question is irrelevant since double-stranded DNA is always easy to separate due to the hydrogen bonds that hold them together.
D.After 150 years of research into DNA, no one knows the true answer to this question.
Answer:
1. A
2. C
3. B
Explanation:
1. The DNA here has a Guanine(G) content of 15% and as G is equal to C,
[tex]$GC=G+C$[/tex]
= 15% + 15%
= 30%
As the GC content is less than 50 % , so the DNA is not a GC rich DNA. Therefore, for a DNA to be GC rich in content, G+C should be more than 50%.
Therefore the correct option is (A), The strand has a GC content of 30%.
2. With a content of 15% Guanine, we calculate the proportions of the four bases. They are :
[tex]$A+T=G+C$[/tex] and [tex]$A=T, G=C$[/tex]
∴ [tex]$A+T=15\% +15\%$[/tex]
[tex]$=30\%$[/tex]
So when we substract 30% from 100% , we get 70%. Now this 70% is then distributed in the equal proportions for [tex]$A$[/tex] and [tex]$T$[/tex].
Therefore, we have:
[tex]$A=30\%, T=35\%, G=15\%$[/tex] and [tex]$C=15\%$[/tex]
Therefore we calculate the content of purines [tex]$(A,G)$[/tex] and pyrimidines [tex]$(C,T)$[/tex].
Purine content : [tex]$A+G = 35\% + 15\%$[/tex]
[tex]$=50\%$[/tex]
Pyrimidine content : [tex]$C+T=15\%+35\%$[/tex]
[tex]$=50\%$[/tex]
Therefore, the correct option is (C).
3. Yes, the GC rich strand of the DNA is more stable the a GC low content DNA. But this stability is not due to the hydrogen bonds, it is mainly due to the stacking interaction known as base stacking.
So the correct option is (B).

Explain the relationship between crossing over and genetic variation
Answer:
When homologous chromosomes form pairs during prophase I of meiosis I, crossing-over can occur. Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. It is obviously another source of genetic variation in offspring.
