When a positively charged object moves in the same direction as the electric field, the electric potential energy of the object?

Biology

Answer: option 2. increases

Explanation: The work done to move a charge in an electric field is given by:

U = F.d = F d cos θ

where F is the electric force between two charges and d is the distance between two charges and θ is the angle between the direction of force exerted and direction of displacement of charge.

F = q E

Where, q is the charge and E is the electric field.

⇒ U = q E d cos θ

When a positively charge object moves in an electric field in the same direction, θ = 0°, cos 0°= 1

⇒ U = q E d

As the charged object moves, d would increase. Electric field (E) and charge (q) are constant. Hence, the electric potential energy  would increase.

Suppose that allele D produces tiny ears and allele d produces normal ears. A heterozygous male with the Dd genotype mates with
kotegsom [21]

Answer:

The correct answer is 35 percent.

Explanation:

Allele D produced tiny ears, and allele d produces normal ones. If a heterozygous male with Dd mates with the homozygous female with dd, then generally, the expected offspring produced will be 50 percent with tiny ears, and 50 percent with normal ears.  

However, in the given case, the penetrance is 70 percent. Thus, the probability of the offspring with tiny ears will be:  

Penetrance = 70 %

Probability = 70 % of 50 % of 100

= 70/100 * 50/100 * 100

= 35 %

Hence, the probability of the offspring with tiny ears is 35%.

2. In some dogs the allele for barking is dominant to the allele for non barking. How would a breeder get a strain of pure breed
OLga [1]

Answer:

Explanation:

Dominant traits are traits that are visible in the phenotype of an organism.

If barking is dominant in some allele of the dog and it has both male and female then a cross between the male and female with the dominant allele for barking will give a strain of pure breeder barkers.

A recessive allele cannot breed a pure barker because it does not have the allele for barking.

Hence a cross between two individual that dominos of the allele will breed true type.

which of the following is a true statement about freezing? a. the substance's energy level decreases. b. the substance's energy
gladu [14]
With Freezing.... the substance energy level decreases.  
 
          Freezing is endothermic and as such energy is lost to the environment
          from the substance thus decreasing the energy level.
