Answer:
D. 0.7 would be wild-type healthy
E. 0.3 would be affected Gg
Explanation:
Using the Punnett square we cross an homozygous male (gg), that is always healthy vs an heterozygous female (Gg). The result is 2 gg individuals, and 2 Gg individuals. Both gg individuals are healthy.
In a population of 1000 Gg individuals, 600 show the Gumball phenotype (unhealthy). It means that from the two heterozygous Gg (from the Punnett square), 1.2 show the unhealthy phenotype.
Again, from the Punnett square we have 4 individuals, that represent the 100%. 1.2 are unhealthy Gg, and represent 30% in F1.
This 30%, is equivalent to 0.3, that is the option E.
100 - 30 % = 70 %. This is 0.7 for healthy wild-type, option D.
What team are you talking about
There is no theory here.
Myron has offered one hypothesis to explain his observations.
There are other possible hypotheses.
They include:
-- An infected mosquito might have bitten him while he slept,
and the results of the infection might be starting to show up.
-- He might have eaten something for dinner last night
that was slightly spoiled.
-- He might have imbibed too much beer for his own good
at the fraternity party last night.
-- There may be too much Carbon Dioxide in the classroom air.
-- His body may be reacting to the physical stress of running to class.
So far, Myron only has a hypothesis.
He's in no position to come to any "conclusion" until he tests
his hypothesis, and shows that the same results follow the same
conditions MOST of the time. His hypothesis may be difficult to
test, but until he does that, he doesn't have a theory.
My personal opinion is that while his hypothesis may also be correct,
the most likely source of his observation is the recent physical stress
of running to class. It's important to understand that I'm in no position
to try and convince anyone of this conclusion. My opinion is simply
another hypothesis. It carries no weight until it's tested.
The velocity of tennis racket after collision is 14.96m/s
<u>Explanation:</u>
Given-
Mass, m = 0.311kg
u1 = 30.3m/s
m2 = 0.057kg
u2 = 19.2m/s
Since m2 is moving in opposite direction, u2 = -19.2m/s
Velocity of m1 after collision = ?
Let the velocity of m1 after collision be v
After collision the momentum is conserved.
Therefore,
m1u1 - m2u2 = m1v1 + m2v2
Therefore, the velocity of tennis racket after collision is 14.96m/s
Answer:
457.81 Hz
Explanation:
From the question, it is stated that it is a question under Doppler effect.
As a result, we use this form
fo = (c + vo) / (c - vs) × fs
fo = observed frequency by observer =?
c = speed of sound = 332 m/s
vo = velocity of observer relative to source = 45 m/s
vs = velocity of source relative to observer = - 46 m/s ( it is taking a negative sign because the velocity of the source is in opposite direction to the observer).
fs = frequency of sound wave by source = 459 Hz
By substituting the the values to the equation, we have
fo = (332 + 45) / (332 - (-46)) × 459
fo = (377/ 332 + 46) × 459
fo = (377/ 378) × 459
fo = 0.9974 × 459
fo = 457.81 Hz
