Answer:
The probability that this couple will have a child with Duchenne Muscular Dystrophy is 50/50
Explanation:
This Punnett square shows our woman as "xx" and our man at "xy". Knowing this, we can now look back at the Punnett square's results. Out of the four squares, two of them are fill with the woman's carried condition, but the other two are also filled with the man's. So, that leaves us with a 50 percent chance that their child will have DMD.
Hope this helped!

Explanation:
The planet Mars has two moons. Phobos and Delmos (i) phobos has period `7` hours, `39` minutes and an orbital radius of `9.4 xx 10^(3) km`. Calculate the mass of Mars. (ii) Assume that Earth and mars move in a circular orbit around the sun, with the martian orbit being `1.52` times the orbital radius of the Earth. What is the length of the martian year in days? `(G = 6.67 xx 10^(-11) Nm^(2) kg^(-2))`
Answer:
D
Explanation:
All the body's systems are linked together in some way. They all interact to produce a fully functioning organism.
A is not correct, becomes hormones are part of the endocrine system, not the immyne system.
B is not correct, because they are not explicitly involved in homeostasis
C is incorrect, all the systems are always working in the background.
The correct answer is D, one way in which the two systems are linked is that the cells of the immune system need to circulate around the body. The circulatory system is incredibly important for this, ensuring that the cells can reach their target sites
All plant and animal groups existing together and the physical factors with which they interact compose an ecosystem<span>.</span>
Explanation:
Observations allow us to collect data that we can connect back to the central problem. From this data we can start to form hypotheses (predictions on possible solutions or outcomes).
