<span>Mark may be getting lower amounts of nutrients and vitamins, namely omega-3s and omega-6s. This would directly affect the brain and normal body functions because the body needs vitamins/nutrients to thrive. This could affect the chemical balance in his brain, resulting in depression/schizophrenia/other issues, including eating disorders. Cutting down on fats might also result in overeating carbs and protein, which leads to an overbalance of nutrients -- and a host of other health issues.Not getting enough fat could also affect bone growth.</span>

If someone was born with Jacob’s syndrome (XYY), in which parent and when nondisjunction happened during gamete formation?
Alex_Xolod [135]
Nondisjunction occurred during spermatogenesis in the father. The mother always provides an X chromosome. The gender of the child is determined by whichever sex chromosome (X or Y) was given from the father. It is only possible for a Y chromosome to come from the father.
Hope that helped you.

A research group discovers a new version of happyase, which they call happyase*, that catalyzes the chemical reaction HAPPY SAD.
notka56 [123]

Answer:

a. kcat = Vmax/[Et] = (1.6 \muM/s) / 0.004 \muM = 400 s-1

b. Vmax = [Et] kcat = [1 nM] (400 s-1) = 400 nM/s which is 0.4 \muM/s.

Now we can use the Michaelis-Menten equation if all the units are similar (all molar conc in nM or in this case \muM):

V0 = Vmax*[S] / Km+[S] = 0.3 \muM/s = (0.4 \muM/s) (30 \muM) / (Km+30\muM)

Then solving for KM, we get:

(0.3 \muM/s) (Km + 30 \muM) = 0.4\muM/s (30 μM)

0.3 \muM/s(Km) + 9 \muM2/sec = 12 \muM2/s

0.3 \muM/s(Km) = 3 \muM2/s

Km = 10 \muM

Another way to do this would be to first rearrange the Michaelis-Menten equation to:

V0/Vmax = [S] / Km+[S]

(300 nM/s) / (400 nM/s) = 3/4 = [S] / (Km + [S])

4 [S] = 3 Km + 3[S]

Km = [S]/3 = 30 \muM / 3 = 10 \muM

c. After removal of ANGER, the Vmax increased to 4.8 \muM/s and the Km became 15 \muM. It is a mixed because it is affecting both Vmax and Km.

Because Vmax increased by a factor of 3, \alpha'=3.

Similarly, Km varies as a function of \alphaKm/\alpha'. Given that Km increased by a factor of 1.5 when ANGER was removed (that is, the inhibitor decreased the observed Km by 2/3 and \alpha'=3, then \alpha=2.

d. Because both \alpha and \alpha' are affected, ANGER is a mixed inhibitor.

Addition of large amounts of salt to soil in which plants are growing kills the plants. explain
salantis [7]
<h2>When salt+water enters the soil, the plant tries to absorb it throughout its roots like normal water. However, salt+water does not allow for osmosis through the plant tissues. It is so dense that the salt solution actually draws water out of the plant, dehydrating and eventually killing it</h2>
