B. it makes your results more convincing

Explanation:

It is important to conduct multiple trials in an experiment because it makes results more convincing.

Multiple trials removes and spreads error from one or more steps in experiment.

  • The ability to reproduce result in an experiment is known as precision.
  • Precision is very important in experiments.
  • When a scientist carries out multiple trails in an experiment, it helps to remove any likely error that might have been carried into the experiment.
  • Multiple trials are key to efficiency of experiments.
  • From the results we can confidently state findings based on statistically backed data obtained.

Antennae development in ants is thought to be a trait controlled by maternal effect. In ants, zig-zag coils are dominant to curl
Schach [20]

Answer:

a. Her mother has zig-zag antennae.

b. Her brother has zig-zag antennae.

Explanation:

<u>Available data</u>:

  • Antennae development ⇒ controlled by maternal effect
  • Zig-zag coils are dominant
  • Curly coils are recessive
  • A female develops zig-zag coils

Maternal effect: Refers to the influence of the “environment provided by the mother” on the progeny phenotype. The mother´s genotype directly determines the progeny phenotype. Even though the progeny has a different genotype, it is irrelevant, as well as the father´s genotype or phenotype. This means that no matter what is the genotype of the offspring, all of them will express the same phenotype as their mother. The maternal effect is commonly seen in insects and might be seen in some mammals and plants.

So, if a female has zig-zag coils, this means that the mother also has zig-zag antennae and that all the brothers and sisters of this female ant have zig-zag antennae, independently of their genotype.

a. Her mother has zig-zag antennae ⇒ True. The trait is inherited from the mother.  

b. Her brother has zig-zag antennae ⇒ True. The whole progeny will express sig-zag antennae.

c. This female carries the zig-zag allele ⇒ Not necessarily.

d. This female's offspring will have zig-zag antennae ⇒ Depends on it´s genotype

In this circuit, there is a resistance of 100 Ω and a current of 0. 05 A, what is the voltage?
kow [346]

Answer:

5V

Explanation:

Given parameters:

Resistance  = 100Ω

Current = 0.05A

Unknown:

Voltage  = ?

Solution:

The voltage is the force that drives current through a circuit. According to ohms law, it is related to current and resistance using the expression below;

         V = IR

Insert the parameters and solve;

    V = 100 x 0.05 = 5V
