<em>50% of the sons have the disorder. </em>
<em />
When this couple has children, one half of their sons will have the disorder. When a male has an X-linked, recessive disorder, his genome will be YXₙ, where Xₙ represents his affected X-chromosome. Since boys can only have one X-chromosome, they cannot be carriers. Having one affected X-chromosome makes them have the condition. His wife, who is not a carrier and does not have the condition will have the genome XX. As you can see in the punnet square, this cross will lead to two sons, one of which has the color-blindness gene. So, 50% of the sons will have the disorder.
Answer:
Evidence of evolution can be identified through fossil records, testimonial fossils, biography, anatomy, and embryology. An example of a species DNA is the peppered moth, whereby light-colored moths are eaten by birds, unlike the dark colored ones which seem to camouflage on dark backgrounds. Evolution changes the genetic makeup of a population over time and may happen on a large scale or small scale basis which affects either one of a few genes over a short period.
Answer:
HBr
Explanation:
As per the given options, HBr could be considered the strongest acid and the strength of its bond that makes it the strongest acid. This acid is highly precarious and toxic in comparison to other acids. It is so strong that <u>it can immediately disunite and concedes its protons in suspension</u> later. It is also <em><u>strong as it gets ionized completely in an aqueous solution and also due to the hydronium ions formation on suspension</u></em>. The other compounds do not do so.
Answer: b. false!
Explanation: i hope this helps!
The incorrect statement is: C) It transports mainly sugars and amino acids.
Xylem together with floem is a plant tissue involved in the transport of substances through the plant.
Xylem’s role is to transport water (sometimes and nutrients) from roots to stems and leaves and to provide support to the plant. Xylem consists of a specialized, water-conducting cells - tracheary elements (tracheids and vessel) which are long, narrow and hollow.
