The appropriate response is active transport. Active transport is the development of particles over a cell layer from a district of their lower focus to a locale of their higher fixation—toward some inclination or another deterring factor.
Active transport utilizes cell vitality to move them against an angle, polar repugnance, or other resistance.

The answer should be true. As long as both forces are unbalanced, an object is going to move in the direction where the most force is being applied.

Purple flowers are dominant over white flowers. A heterozygous purple flower is crossed with another heterozygous purple flower.

Anna007 [38]

You need to draw a punnet square:
_______
__|P | w |
|P |PP| Pw|
|w |Pw| ww|

So that means you'll have:
1/4 PP flowers, which are homozygous purple flowers
2/4 Pw flowers, which are heterozygous purple flowers
1/4 ww flowers, which are homozygous white flowers

So the ratio of purple to white flowers is 3:1

Someone please help me with Punnett square

anygoal [31]

Answer:

1. Phenotype ratio = 3:1

Genotype ratio = 1:2:1

2. Phenotype ratio = 4:0

Genotype ratio = 4:0

3. Phenotype ratio = 1:1

Genotype ratio = 1:1

Explanation:

According to this question, a gene coding for tallness is involved. The allele for tallness (T) is dominant over the allele for shortness (t). The phenotype and genotype ratio of each parental combinations is given in the attached punnet square.

1. Tt × Tt

In this cross, both parents (Tt) will produce T and t gametes. Using this in a punnet square, the offsprings will be as follows: TT, Tt, Tt, and tt. Hence, The phenotype ratio is 3 tall: 1 short while genotype ratio is 1(TT): 2(Tt) : 1(tt).

2. TT × tt

In this cross, TT will produce T gametes while tt will produce t gametes. Using this in a punnet square, all offsprings will be heterozygous "Tt". Hence, The phenotype ratio is 4 tall: 0 short while genotype ratio is 4 (Tt) : 0 (tt).

3. tt × Tt

In this cross, tt will produce t gametes while Tt will produce T and t gametes. Using this in a punnet square, the following offsprings will result: Tt, Tt, tt and tt. Hence, The phenotype ratio is 1 tall: 1 short while genotype ratio is 1(Tt) : 1(tt).

Help I need to turn this in asap

Answer:

The P waves undergoes compression and dilation during motion in its direction of propagation. This waves reaches the station first because the P waves travels at a speed, that is much faster in comparison to the S waves. The S waves are the secondary waves and are commonly known as the shear waves.

The P waves have the ability to travel in both solid as well as in liquid, whereas the S waves can propagate only in solid region because they are absorbed at the core-mantle boundary.

Thus, the P waves will arrive the station first and the difference between the arrival of P and S waves are plotted in the graph that helps in depicting the epicenter and the amount of energy released during an earthquake.
