Which feature of the kinetics of L-Alanine transport would provide evidence that DOM is an important source of nutrients under low-food conditions?
High affinity transport (Kt) of L-Alanine
-Under low food conditions, the capacity of transport is irrelevant as no transporters are saturated with L-alanine
-However, the transporter's affinity for L-alanine would be important as only HIGH AFFINITY transporters will be able to facilitate L-alanine uptake at low concentrations
High affinity transport (Kt) of L-Alanine feature of the kinetics of L-Alanine transport would provide evidence that DOM is an important source of nutrients under low-food conditions.
This biochemistry question is categorized as "Assemblies of molecules, cells, and groups of cells within single cellular and multicellular organisms" in terms of its subject matter. The answer to this issue is A because no transporters are saturated with L-alanine under low-food conditions, making the transport capacity unimportant. Only high affinity transporters would be able to assist L-alanine uptake at low concentrations, hence the transporter's affinity for L-alanine would be crucial.
Because you are expected to utilize your understanding of transport kinetics to forecast the characteristics of transport that would be significant under low L-alanine conditions, this question falls under the category of scientific reasoning and problem solving.

Duchenne muscular dystrophy (DMD) is a recessive, sex-linked disorder carried on the X chromosome. If a woman who is a carrier of DMD and a man without the disorder have children, which outcome is possible?
a. All of their sons and half of their daughters could have DMD.
b. Half of their sons and half of their daughters could have DMD.
c.Half of their sons and none of their daughters could have DMD.
d. None of their sons and half of their daughters could have DMD.
Answer:
C. Half of their sons and none of their daughters could have DMD.
Explanation:
DMD is a recessive disorder carried on the X chromosome and it is sex-linked. This means that the gene for DMD is located on the X chromosome and it affects mostly males.
If a woman is a carrier of DMD, it means that she has one copy of the mutated gene and one normal copy, and she does not show any symptoms of the disorder.
If a man without the disorder has children with this carrier woman, half of their sons will inherit the mutated X chromosome from the mother. Therefore, they will have the disorder and half of their sons could have DMD.
Since, Females have two X chromosomes, and therefore, if a daughter inherits the mutated X chromosome from the mother, the second X chromosome will be normal which will help in compensating the effects of the mutant one, hence they will be carrier of the disorder but will not show any symptoms. So none of their daughters could have DMD.
So, the outcome is: C. Half of their sons and none of their daughters could have DMD.
Answer:D
Explanation:
I think it is D because only the mother had it and not the father. I don't think the father could get DMD through sex either. So I think that none of their sons and half the daughters could have DMD because they inherited it from the mother.

One allele for the dominant phenotype and one for the recessive phenotype are present in the F1 offspring of a cross of two pure lines.
In the 19th century, Mendel performed thousands of experiments with pea plants. He came to the further conclusion that genes are inherited as distinct, paired units from each parent.
