Explain in 2-3 sentences how a genotype determines a phenotype! <br> Will give b to the best one
allochka39001 [22]

Answer:

Genotype can be determined by biological tests. Both the genotype and phenotype sounds similar but have differences. The phenotype is determined by an individual’s genotype and expressed genes or by visible trait, for instance, hair color or type, eye color body shape, and height. We are all unique. Even monozygotic twins, who are genetically identical, always have some variation in the way they look and act. This uniqueness is a result of the interaction between our genetic make-up, inherited from our parents, and environmental influences from the moment we are conceived.

Consider a field of insects, all of which have essentially the same mass.
Over [174]

If the total momentum of the insects is zero, this means all of the insects are at rest or are moving in opposite of each other. Same if the total kinetic energy is zero.

<h3>What is momentum? </h3>

Momentum is the quantity of motion which is multiplied by the amount of matter moved i.e., mass and the velocity at which it moves. Because, the object is in motion, it is a vector quantity, it has both direction and magnitude. It is determined by the product of the object's mass and the velocity of object.

If the total momentum of the insects is zero, this could mean anything of the two things. Either, all of the insects are at rest or an equal amount of insects are moving in opposite direction of each other which cancels out the total momentum of the insects.

If the total kinetic energy of the insects is zero, this means either all of the insects are at rest or an equal amount of insects are moving in opposite direction of one another which results into canceling out the energy.

In order to increase the kinetic energy of a speeding train by 44%, 42MJ of work must be performed (1 MJ = 106 J). If the final
victus00 [196]

Answer:

Explanation:

100 % increase makes an amount 2 times .

44 % increase = 42 MJ

100 % increase = 95.45 MJ

final kinetic energy = 2 x 95.45 MJ

= 190.9 x 10⁶ J

1/2 m v² = 190.9 x 10⁶

.5 x m x 9² = 190.9 x 10⁶

m = 4.71 x 10⁶ kg

= 4710 metric ton .
