Enzymes are (usually) specific to the substrates they bind to. Thus, each enzyme has one and only one substrate structure they can metabolize, so even substrates with similar structures cannot be broken down by an enzyme specific to one of them.

A plane is traveling at 80 m/s. To prepare for landing, it decreases its speed to 50 m/s in 120 s.
emmainna [20.7K]

Answer:

The deceleration of the plane is 0.25 m/s^{2}.

Explanation:

Deceleration is the converse of acceleration.

From first law of motion, we have;

v = u + at

where: v is the final velocity, u is the initial velocity, a is the acceleration and t is the time taken.

Thus,

v = 50 m/s

u = 80 m/s

t = 120 s

50 = 80 + 120a

50 - 80 = 120a

-30 = 120a

a = \frac{-30}{120}

  = -0.25

a = -0.25 m/s^{2}

The deceleration of the plane is 0.25 m/s^{2}.

1. Anaphase. In <span>Anaphase the sister chromatids separate from each other to the opposite sides of the cells.

2. </span>Chromosomes would not separate into two nuclei. <span>Mitosis is a process cell division, where one cell divides into two identical cells.
</span>
3. Metaphase I. <span>Meiosis prophase I is the phase in which chromosomal crossing over occurs. The phase after prophase I is metaphase I.

4. </span>Its body cells would have 36 chromosomes, and its gametes would have 18 chromosomes. <span>In the gametes, there are half of the number of chromosomes present in the body cell.

5. </span><span>A species has to adjust rapidly to a changing environment. To adjust to the environment, crossing over is necessary, and it does not occur in mitosis, but meiosis.

6. 50 percent. 
Parents:          Yy      x     yy
Offspring:    Yy    Yy    yy   yy
50 % is Yy  and 50% is yy.

7. </span><span>One parent had white eyes and the other was heterozygous for eye color. The ratio in the offspring is 50-50. The only possibility is the following:
Parents:       Rr     x     rr
Offspring   Rr    Rr   Rr   Rr

8. </span><span>Their fur will be a mixture of red and white hairs. The offspring will be heterozygous. They will have alleles for both red and white hairs and both will be expressed.
</span>
9. Not enough information.

10. <span>Both of the parents' genotype must have been Pp. The genotype of the white plant is pp since it is recessive:
Parents:        Pp     x     Pp
Offspring:   PP   Pp   Pp   pp
One of the four is white.</span>
