Joe is color blind. His mother and father have normal vision, but his mother's father (Joe's maternal grandfather) is color blind. All Joe's other grandparents have normal color vision. Joe has three sisters-Patty. Betsy, and Lora, all with normal color vision. Joe's oldest sister. Patty, is married to a man with normal color vision; they have two children, a 9-year-old color-blind boy and a 4-year-old girl with normal color vision. a. Using correct symbols and labels, draw a pedigree of Joe's family. Take a picture and send it by email.
b. What is the most likely mode of inheritance for color blindness in Joe's family?
c. If Joe marries a woman who has no family history of color blindness, what is the probability that their first child will be a color-blind boy?
d. If Joe marries a woman who is a carrier of the color-blind allele, what is the probability that their first child will be a color-blind boy?
Answers
Answer:
a. Using correct symbols and labels, draw a pedigree of Joe's family. Take a picture and send it by email.
The pedigree image is attached at the end.
(b) What is the most likely mode of inheritance for color-blindness in Joe’s family?
X-linked recessive. Only males have the trait, and they inherit the trait from
their mothers, who are carriers. The trait is never passed from father to son.
(c) If Joe marries a woman who has no family history of color-blindness, what is the probability that their first child will be a color-blind boy?
Barring a new mutation or nondisjunction, zero. Joe cannot pass his color-blind X chromosome to his son.
(d) If Joe marries a woman who is a carrier of the color-blind allele, what is the probability that their first child will be a color-blind boy?
The probability is ¼. There is ½ probability that their first child will be a boy,
and there is an independent ½ probability that the first child will inherit the
color-blind X chromosome from the carrier mother. ½(½) = ¼.

All of the world's plants, animals, and microorganisms are included in taxonomy, which is the science of naming, describing, and classifying species.
What is Taxonomy?Taxonomists identify, describe, and classify species, particularly those that are novel to science, using morphological, behavioral, genetic, and biochemical observations.
Taxonomy recognizes and catalogs the elements of biological diversity, offering the fundamental information necessary for the management and application of the Convention on Biological Diversity.
Taxonomists have identified roughly 1.78 million species of animals, plants, and microorganisms throughout the past 250 years of study, but the true number of species is unknown and likely between 5 and 30 million.
Therefore, All of the world's plants, animals, and microorganisms are included in taxonomy, which is the science of naming, describing, and classifying species.

Answers
Answer:
d. convergent evolution
Explanation:
Convergent evolution refers to the independent evolution of similar phenotypic/morphological traits in organisms that are not closely related (i.e., they are not monophyletic). Convergent evolution leads to the development of analogous structures, i.e., similar structures that have the same/similar purposes but were not present in the last common ancestor of these groups. A well-known example of convergent evolution is the wings of the butterfly and bat. Conversely, divergent evolution is a type of pattern of evolution that leads to the accumulation of phenotypic differences between closely related species/populations/individuals.

Caenorhabditis elegans is a species of soil-dwelling nematode (roundworm) that feeds on soil bacteria, including Bacillus thuringiensis. B. thuringiensis is a virulent bacterial pathogen that produces BT toxin, a protein that can kill different invertebrate species, including C. elegans. In a laboratory experiment, C. elegans and B. thuringiensis were cultured individually (control) or together (experimental) for 150 days. Under optimal conditions, the generation time of C. elegans is approximately 3.5 days and the generation time of B. thuringiensis is approximately 25 minutes. At the end of the experiment, the change in virulence of B. thuringiensis and the change in resistance of C. elegans to BT toxin were determined. The researchers found that after 150 days, the magnitude of the change in both B. thuringiensis virulence and C. elegans resistance was less when they were cultured individually (control) than when they were cultured together (experimental). Provide ONE reason for the difference in results between the two treatments.
Answers
Answer:
i).number of generations that is possible in individual cultures of C. elegans is 42 .
ii)number of generations that is possible in individual cultures of B elegans IS 8640.
b). When the Caenorhabditis elegans and bacillus thuringiensis have controlled growth their are no immune response to each other hence they are not adapted to each other for separate growth.
c)The relative change in B. thuringiensis virulence was greater than the relative change in C. elegans resistance because B thuringiensis had more number of generation event 8640 after 150 days while C elegans had less number of reproductive event 42.
Step-by-step explanation
explanation.
a) i).number of generation for C elegans will be given by;
growing period divided by generation time.
we have ;
generation time is 3.5 day
growing period is 150 day.
then number of generation of c will be;
150/3.5=42 generation
ii).number of generation for B thuringiensis is given by;
but we have;
generation time is 25 minutes
growing period is 150 days.
then substituting in the formulae we have ,
150 x24 x60/25=8640 generation.
we have used the relation ;
1 hour =60 minutes and 1 day = 24 hours
b).When the Caenorhabditis elegans and bacillus thuringiensis have controlled growth their are no immune response to each other hence they are not adapted to each other for separate growth. when grown together they provide the host pathogen relationship protecting the growth for each organism. B thuringiensis secrets toxin to infect the host hence having much change while C elegans are protected from this chemical since the change is high.
c).The relative change in B. thuringiensis virulence was greater than the relative change in C. elegans resistance because B thuringiensis had more number of generation event 8640 after 150 days while C elegans had less number of reproductive event 42.
B. thuringiensis have smaller genome size hence have more change .This change is caused when trying to infect C elegans hence causing a more diverse change in B thuringiensis.
C elegans genome are relatively high since they have less number of reproductive event hence being protected because they produce the immune response by growing together to show maximum changes when separately grown.

Answer:
The correct answer is - Mitochondria.
Explanation:
Mitochondria is the location that stores the energy in food until it is released. It is the cellular organelle that is the place where the cellular respiration process takes place.
In this organelle, the stored food is converted into a usable energy form, ATP. Mitochondria is also known as the powerhouse of the cell as it converts and releases the energy from the stored sugar or food.
Thus, the correct answer is - mitochondria.
