Gaaffii 1

A city Municipality following the ban of non-degradable plastic bags, proposed to use genetically engineered bacterium to degrade plastic wastes for making bags. However, an authority claims the use of bioengineered bacteria due to the fear of its negative consequences on the environment. Based on this scenario, which decision is valid?

  1. A.accepted with stringent protocols to reduce its effect.
  2. B.rejected since the city can use already existing materials for packing.
  3. C.accepted whatever the environmental consequences it caused.
  4. D.rejected since the municipality can use the native species.
Deebii fi ibsa ilaalaa

Deebii: A accepted with stringent protocols to reduce its effect.

Maaliif

While using bioengineered bacteria has environmental risks, adopting the technology with stringent safety protocols is the scientifically valid approach to mitigate those risks while addressing the plastic waste problem.

Gaaffii 2

This item is based on the following mechanism of hearing in human ear. I. Nerve impulses produced by hair-like sensory cells are transmitted to, and interpreted by the brain. II. Ear ossicles amplify vibrations and cause vibration of the ear fluid. III. Sound wave from the air is collected by pinna and directs to the ear canal. IV. Vibrations are magnified in eardrum and transmitted to oval window. Then which of the following order summarizes correct path of hearing in human ear?

  1. A.III, I, II, IV
  2. B.III, II, IV, I
  3. C.III, IV, II, I
  4. D.III, IV, I, II
Deebii fi ibsa ilaalaa

Deebii: C III, IV, II, I

Maaliif

The correct path of hearing is: Pinna collects sound (III) → Eardrum vibrates (IV) → Ossicles amplify vibrations (II) → Nerve impulses sent to brain (I). The correct sequence is III → IV → II → I.

Gaaffii 3

Which one of the following is the industrial importance of insects?

  1. A.Serving as pollinating agents for plants
  2. B.Producing silk fibers for textiles
  3. C.Controlling pests that attack crops
  4. D.Serving as the source of pain-relieving drugs
Deebii fi ibsa ilaalaa

Deebii: B Producing silk fibers for textiles

Maaliif

Sericulture (the rearing of silkworms) is a major industrial process used to produce silk fibers for the textile industry.

Gaaffii 4

Two processes were taking place inside a eukaryotic cell. In process A, a ribosome made a specific protein by reading the instructions from mRNA. In process B, an mRNA was synthesized inside the nucleus. Based on this scenario, which of the following processes correctly 2018 Biology First Round represents A and B respectively?

  1. A.Translation and Replication
  2. B.Transcription and Translation
  3. C.Replication and Translation
  4. D.Translation and Transcription
Deebii fi ibsa ilaalaa

Deebii: D Translation and Transcription

Maaliif

Process A (ribosome reading mRNA to make a protein) is Translation. Process B (mRNA synthesis in the nucleus) is Transcription.

Gaaffii 5

Which one of the following statements is correct about regulation of enzyme through covalent modification? It happens through the

  1. A.permanent binding of effectors to the active site of an enzyme.
  2. B.addition or elimination of some molecules attaching of enzyme protein.
  3. C.reversible binding of effectors to the allosteric site of an enzyme.
  4. D.inhibition of the enzyme by the end product of a pathway.
Deebii fi ibsa ilaalaa

Deebii: B addition or elimination of some molecules attaching of enzyme protein.

Maaliif

Covalent modification regulates enzyme activity through the addition or removal of specific chemical groups (e.g., phosphate, methyl) to/from the enzyme protein.

Gaaffii 7

A farmer crossed a heterozygous insect-resistant maize with a non-insect resistant maize variety, where insect-resistance gene is dominant over non-resistance one. What is the probability of the offspring resulted from this cross?

  1. A.75% resistant and 25% are non-resistant to insect infestation.
  2. B.50% resistant and 50% are non-resistant to insect infestation.
  3. C.25% resistant and 75% are non-resistant to insect infestation.
  4. D.100% of the offspring are resistant to insect infestation.
Deebii fi ibsa ilaalaa

Deebii: B 50% resistant and 50% are non-resistant to insect infestation.

Maaliif

A cross between a heterozygote (Rr) and a homozygous recessive (rr) yields 50% Rr (resistant) and 50% rr (non-resistant).
