The only people with Rh negative blood are people who have inherited two recessive alleles for this trait. But some people who are colorblind have inherited only one recessive allele for this trait. Explain why these traits are different in terms of how many recessive alleles are needed to produce the recessive phenotype. Hint: Think about the above problem and sex chromosomes versus autosomes.
The difference is due to the inheritance pattern. Blood type needs two recessive alleles to express Rh-. Color-blindness needs only one.
What are the blood type and Color-blindness inheritance patterns?
⇒ Blood type is coded by a diallelic Rh gene that expresses complete dominance.
The allele Rh+ dominates over the allele Rh-.
Genotyopes and Phenotypes are as follows,
Individuals Rh+Rh+ express the possitive phenotypeIndividuals Rh+Rh- express the possitive phenotype Individuals Rh-Rh- express the negative phenotype.To express Rh-, a person must inherit two recessive alleles from their parents.
⇒ Color-blindness is an X-linked condition coded by a recessive allele.
As most sex-linked genes, it is transmitted together with the X chromosome.
The phenotype depends on the number of recessive alleles and the sex of the person.
Genotyopes and Phenotypes are as follows,
X⁺X⁺ women have normal sight.X⁻X⁻ women are completely color-blinded X⁺X⁻ women are partially color-blinded. X⁺Y Men are not color-blinded X⁻Y Men are color blinded.In this case, only one recessive allele is enough to express the affection.
In conclusion, Blood type needs two recessive alleles to express Rh-. Color-blindness needs only one recessive allele.

a.genetic variation
b.improves chances of adapting to the envionment
c.helps species survive catastrophes
d.Certian genes work beter than other
Some advantages of the sexual reproduction include genetic variation. Genetic variation results into changes in the genetic material (DNA). Thus, the correct option is A.
What is Genetic variation?Genetic variation is the difference in the DNA (deoxyribonucleic acid) among individuals or the difference between different populations. The multiple sources of genetic variation include mutations and genetic recombination. Mutation is the changes in the genetic material of an organism which are the ultimate sources of genetic variation, however other mechanisms, such as genetic drift, contribute to it, as well.
Genetic diversity is important because it gives the species a better chance of survival through variations. However, the genetic diversity can be lost from the species when the populations get smaller and isolated from each other, which decreases a species' ability to adapt and survive better in the condition.
Therefore, the correct option is A.

The correct answer is A.
From the given graph, the condition that is best for enzyme activity can be inferred as the temperature of about 25°C.
Enzymes are organic molecules that act as catalysts and aid the biochemical reactions that occur in living organisms. Enzymes usually function under specific optimal conditions, including temperature, pH, and salt concentration. Changes in these conditions may affect the enzyme's performance and ultimately cause a decrease or cessation of the reaction's activity.Temperature, in particular, has a significant effect on enzyme activity. The reaction rate increases as the temperature rises until it reaches the optimum temperature, where the enzyme activity is at its peak. As a result, the optimum temperature promotes the highest possible reaction rate, while high or low temperatures may reduce the enzyme's efficacy and cause a decrease in the reaction rate.According to the graph, the optimum temperature for the enzyme activity is approximately 25°C. At 25°C, the relative rate of enzyme activity is maximum, indicating that the enzyme performs optimally at this temperature. In contrast, a temperature of about 0°C would be too low, causing the enzyme to freeze and become inactive. A temperature above 30°C would still be high, causing the enzyme to denature and lose its activity. Lastly, a temperature below 20°C would be too low, causing the enzyme to become inactive due to a lack of energy. Therefore, the optimal temperature for enzyme activity is 25°C.For such more questions on enzyme

When X fires 10 times and Y fires 10 times, the result will be a subthreshold summation.
Subthreshold summation happens when two or more presynaptic inputs that are sub-threshold (i.e., they cannot create an action potential) combine their effects on the postsynaptic neuron.
Here, the postsynaptic neuron has an RMP of -70mV and a typical threshold of -55mV. When neuron X is stimulated, it depolarizes by 0.5 mV.
When X and Y are stimulated simultaneously, the postsynaptic neuron depolarizes by 1 mV, which is sub-threshold (below -55mV).
Therefore, when X fires 10 times and Y fires 10 times, the postsynaptic neuron will experience subthreshold summation and no action potential will be fired.
