The children in a middle school classroom are all exposed to chicken pox one week. Among these students are John, who had chicken pox when he was much younger, and Sara, who has never had chicken pox. Which student do you expect would be less likely to become ill with chicken pox following this exposure and why? (5 points) John: he has naturally acquired active immunity to chicken pox from his previous exposure. Sara: she has naturally acquired passive immunity to chicken pox from exposure to other students. John: the pathogens that cause chicken pox will no longer be able to enter his body. Sara: since she has not suffered from chicken pox, her immune system is probably stronger than Johns.
Answer:
John: he has naturally acquired active immunity to chicken pox from previous exposure.
Explanation:
Your body naturally has some immunity to things that aren't you, but when you get sick with a specific pathogen, your body begins to make antibodies that specifically recognize that pathogen. Each antibody only recognizes one pathogen, and it floats around waiting to find it again so it can tell your body to kill it before you get sick again. This is why we become immune to chicken pox; after the first time you beat it, your body has the labeled antibodies and it can quickly destroy the pathogen before you get sick again.
Answer:
John: he has naturally acquired active immunity to chicken pox from his previous exposure.

why are supergiants bright
Answer:
The luminosity differences between stars are most apparent at low temperatures, where giant stars are much brighter than main-sequence stars. Supergiants have the lowest surface gravities and hence are the largest and brightest at a particular temperature.
Explanation:
(:
Because supergiants are so massive, the core temperature gets much hotter than in giants, so supergiants can fuse elements heavier than hydrogen and helium. But to support their tremendous mass, supergiants burn up their fuel much more quickly. Eventually, all possible fuels are exhausted, the core collapses, and the star goes supernova.
1. Explain how the traits of an organism are related to the genes in DNA.
2. Describe how an organism’s genotype determines its phenotype (include the role of dominant and recessive alleles).
Genes in DNA or responsible for the traits an organism has. This is caused by Dominant and Recessive Traits. Remember that Genotypes are the genetic letters such as RR, Rr, and rr. Phenotype is physical traits.
Dominant Traits are more likely or always show in the offspring. The Dominant Genotype uses Capital letters such as RR.
Recessive Traits are less likely to show up. Their Genotype use lower case such as rr. Now genotypes of Rr have one dominant trait and one recessive trait. If the dominant trait was black fur and the recessive white fur, the offspring will be black fur because dominant traits overpower the other.
To understand how to know if an organism will have Dominant or Recessive Genes, you have to use something called a Punnet Square. Lets imagine 2 parents both have the genotype Rr. R is Black fur and r is white fur. As you can see from the chart, 3 of 4 boxes have Rr and 1 rr. Since there is a Dominant Trait with a Recessive, they will show a Dominant Phenotype, or Black fur. This has 3/4 chance and a 1/4 chance for white fur in the offspring.

3. Preventing natural evolution
2. When calculating the recombinant frequency of two genes, what is
the most important factor?
O A. how close they are to each other
OB. how close they are to the end of the chromosome
Oc. whether they are on the X or Y chromosome
OD. which one is higher on the chromosome
Answer:
A
Explanation:
The most important factor is how close they are to each other.
• The physical swapping of the pieces of chromosomes at the time of meiosis is responsible for the recombination of genes.
• The swapping can take place anywhere along the length of the chromosome, that is, in any part of the gene.
• The recombination frequency between the two genes is equivalent to the ratio of offspring in which the event of recombination took place between the two genes at the time of meiosis.
• The determination of the recombination frequency is done by the frequency of the recombination events between the two genes in meiosis.
• The more the physical distance between the two genes, the more is the probability that the recombination take place during any meiosis event.
Thus, the correct answer is option A.

Which allele combination represents a female who is heterozygous for a sex-linked trait?
XRY
XrY
XRXr
XRXR
C. XRXr
hope this helps :)
The allele combination represents a female who is heterozygous for a sex-linked trait is XRXr. Thus option C is correct.
What is meant by a sex-linked trait?A sex-linked trait is one that is encoded by a gene or an allele that is located on sex chromosomes. The sex chromosomes that are present in females is a pair of XX while in males there is only one X chromosome and one Y chromosome as sex chromosomes.
Most of the sex-linked traits are X-linked as the X chromosomes are larger and contain more genes than the Y chromosome.
The females are the carriers for the sex-linked heterozygous traits for a disease. The males cannot be carriers for such heterozygous traits. So the X-linked trait in males is always inherited from their mother. X-linked dominant traits are more commonly seen in females.

A yellow frog and a blue frog are crossed. The resulting offspring are green. How would you describe the pattern of inheritance?
Answer:
The correct answer is - incomplete dominance.
Explanation:
Incomplete dominance is a type of inheritance in which the dominant allele or gene does not mask the other gene or allele completely and produce a blend or mixture of both alleles in the phenotype.
In this case, where alleles are in their pure breed they show their respective yellow and blue color but after the cross, they produce offspring with the heterozygous condition, and due to incomplete dominance they produce a mixture of both alleles in the offspring.

The system of sex determination in birds is of female heterogeneity. In birds, the sex of birds is determined by the inheritance of the sex chromosomes. Female birds have the heterogametic sex chromosomes ZW, whereas male birds have the homogametic sex chromosomes ZZ. This sex-determining system is highly conserved in the birds, which include nearly ten thousand different species.
