The average length of a specific dinosaur leg bone is 60 inches, with a standard variation of 3 inches. If a z-score is 0, then the length is 67.

Divide your data point by your standard error after taking your data point and subtracting the mean from it. How is the z-score determined? Z-scores are calculated using the formula z = (x-)/, where x represents the raw score, the population mean, & the population variation. The z-score is just the raw score less the population mean, split by the population variance, as the calculation demonstrates. You now have your Z-score. For instance, a scoring of 450 would equate a scores of (450-500)/100 (= -50/100 = -0.50 on a scale with a mean of 500 as well as a standard variation of 100, indicating that the scoring is half a variance below the mean.

G1, S & G2 phase make up this part of the cell cycle ?
ratelena [41]

Answer:

Interphase

Explanation:

Interphase is the G1, or gap 1, phase in which the new cell grows and carries out its functions in the body; the S, or synthesis, phase when the chromosomes replicate; and the G2, or gap 2, phase, when the cell grows further and prepares to divide.

terry physics pushes a 75kg lab cart so that is accelerates from rest with a velocity of 4.4m/s in 3.1 secounds. what is the for
svetlana [45]

106.5N

Explanation:

Given parameters:

Mass of cart = 75kg

Velocity = 4.4m/s

time taken = 3.1s

Unknown:

Force = ?

Solution:

To solve this problem, we are going to apply newton's second law of motion. The law states that "the acceleration of a body is directly proportional to the force on the body and inversely proportional to the mass".

      F = m  x   a

F = force on body

m = mass of body

a = acceleration of the body

 But we know that acceleration is the change in velocity with time of a body;

     a  = \frac{change in velocity }{time}

  F = m x \frac{V}{t}

V is the velocity

t is the time taken

   F = \frac{75  x  4.4}{3.1}   = 106.5N

Which of Thomas hunt Morgan‘s hypothesis was valid
Alexandra [31]

Answer:

White eyes are lethal in male Drosophila was the hypothesis of Thomas hunt which was valid. Hence the answer is option B.

Explanation:

Thomas hunt Morgan was a famous American biologist. He was more famous because of his experiment on drosophila which contributed most of things about the lifestyle and health science in much of the findings about those insects.

He was also awarded by the Nobel prize for his works which was related to medicine in 1933.  He has also contributed many knowledge about the chromosome and heredity. he is finding is very helpful nowadays for the scientist and other biologist.

AVprozaik [17]

Catalysis An enzyme may catalyse a reaction by stressing or destabilizing the bonds of the substrates. This point in the enzymatic reaction is known as the Transition State.  An enzyme can couple a nonspontaneous reaction to a spontaneous reaction so that anabolic processes will occur.
