Answer:

The correct answer will be option-B.

Explanation:

A scientific hypothesis is a statement based on the research work of the earlier work done. The hypothesis is also known as the educated guess and explains the phenomenon to a limited extent which could be tested through experiments.

The hypothesis when proved many times by the repeated experiments by many scientists and supported by a large number of hypothesis and data from the works of the other scientist, the hypothesis gets established and explain the event in-depth and thus becomes a hypothesis.

Thus, Option-B which stated that hypothesis which undergoes extensive testing becomes hypothesis is the correct answer.

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
