In humans, the condition for normal blood clotting (H) dominates the condition for non clotting (hemophilia) (h). Both alleles are linked to the X chromosome. A male hemophiliac marries a woman who is a carrier for this condition. (In this respect, a carrier is a woman who has an allele for normal blood clotting and an allele for hemophilia.) If they have a son, what are the chances he will be normal for blood clotting
Answer:
The correct answer would be - 50%.
Explanation:
Hemophilia is a sex-linked recessive disorder that takes place in males more than in females as females have two X chromosomes so if one is affected other still able to make clotting factors but in males, there are only one x chromosome.
If a hemophilic man XhY marries with a carrier women XHXh then the chances of their son for normal blooding would be :
Gametes:
Male: Xh and Y
Female: XH and Xh
Then cross:
Xh Y
XH XHXh XHY
(carrier daughter) (normal son)
Xh XhXh XhY
(hemophilic daughter) (hemophilic son)
Thus, the chances of normal son is 50% among sons

PLS HELP The diagram below shows the relationship between respiration and photosynthesis.
How is combustion similar to cellular respiration?
Answer/Explanation:
In Cellular respiration, organisms use oxygen to break down down to food molecules in order to produce energy that is needed for body function.
Combustion, which is also known as burning, also involves the use of oxygen in the break down of chemical bonds to produce energy.
Both processes give off carbon dioxide in the process along with the energy they release.
Therefore, both processes seem very much alike.

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.
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.

a. What is the diploid number of the species shown in Figure 1?
b. What is the haploid number of the species?
Answer:
I hope this helps you
Explanation:
1)This number is abbreviated as 2n where n stands for the number of chromosomes. For humans, the diploid chromosome number equation is 2n = 46 because humans have two sets of 23 chromosomes (22 sets of two autosomal or non-sex chromosomes and one set of two sex chromosomes).
2)Under normal conditions, the haploid number is exactly half the total number of chromosomes present in the organism's somatic cells. For diploid organisms, the monoploid number and haploid number are equal; in humans, both are equal to 23.
The diploid number is 2n no. of chromosomes and thus it is diploid instead of haploid.
This variety is abbreviated as 2n wherein n stands for the variety of chromosomes. For people, the diploid chromosome variety equation is 2n = 46 due to the fact that people have units of 23 chromosomes (22 units of autosomal or non-intercourse chromosomes and one set of chromosomes).Under everyday conditions, the haploid variety is precisely 1/2 of the entire variety of chromosomes gift withinside the organism's somatic cells. For diploid organisms, the monoploid variety and haploid variety are identical; in people, each is identical to 23.What are chromosomes?Chromosomes are thread-like systems placed in the nucleus of animal and plant cells. Each chromosome is made from protein and a single molecule of deoxyribonucleic acid (DNA).
Thus it is clear that the diploid and haploid number of the species depends on the number of chromosomes.
