Sam and Jenny ride their bikes at a constant velocity of 3 miles per hour.

Explanation:

Here we see that both of them are moving at a constant velocity which means their speed is constant and they are moving in a straight line.

Zero acceleration is implied on the bikes and the net force is BALANCED.

When forces are in balance, acceleration is zero. Velocity is constant and there is no net or unbalanced force.

Which of the following is the best definition of energy? A. the ability to generate electricity B. the ability to generate heat

PilotLPTM [1.2K]

The phrase that best describe the word "energy" is letter "C. the ability to do work". The unit most commonly used to express energy is Joules (J) which is also derived from the equation of work which is the product of force and the distance that a body moves parallel to the force applied.

Explain Mendel's law of independent assortment and how the 9:3:3:1 phenotypic ratio among the F2 of a dihybrid cross provides ev

GrogVix [38]

Answer:

Explanation:

Mendel's law of independent assortment state that two different genes assort independently in gamete formation.

To reach this conclusion, one has to do a dihybrid cross. This means that two genes responsible for different traits need to be analyzed at the same time.

1) Starting with a parental generation of a cross between two pure lines (homozygous for both genes) with different traits, a plant with yellow and round seeds (YYRR) and another with green and wrinkled seeds (yyrr). The F1 will be phenotypically homogeneous (yellow and round), and genotypically heterozygous (YyRr).

2) If the individuals from the F1 are crossed with one another, we have to do a Punnett Square to determine the phenotypic ratio of the F2.

If the genes assort independently, the F1 individuals will produce their different gametes with the same probability. Each possible gamete will appear in a 1/4 proportion: YR, Yr, yR, yr.
The 9:3:3:1 ratio is a result of analyzing the possible phenotypes that result from the dihybrid cross.

See the attached image for an illustration of the crosses in each generation and the Punnett Square.

Answer: The answer is B- Neurons

Explanation:

Neurons are nerve cells whih are fun units of br nervous system. They are desig to transmit inform to other nerve cells, muscles or glands. They do this by rece sensory input from external forces, send motor commands to muscles, glands or other neurons. They transform and relay electrical signal.

Unlike other cell types they cannot proliferate once they are differentiated. They are non-dividing cells.
