Robert believes that rotten meat gives rise to flies. To what theory of evolution does he adhere to?
A.
Abiogenesis
B.
Biogenesis
C.
Divine creation theory
D.
Extraterrestrial theory
Correct Answer
A. Abiogenesis
Explanation Robert believes that rotten meat gives rise to flies, which aligns with the theory of abiogenesis. This theory suggests that life can arise from non-living matter, such as the idea that flies can emerge from decaying meat. Abiogenesis proposes that the first living organisms on Earth originated from inanimate substances, rather than being created by a divine being or brought to Earth from extraterrestrial sources.

Carbon monoxide has more affinity to hemoglobin compared to Oxygen.
A.
True
B.
False
Correct Answer
A. True
Explanation Carbon monoxide has a higher affinity for hemoglobin compared to oxygen because it forms a stronger bond with the iron in hemoglobin. This means that when both carbon monoxide and oxygen are present in the bloodstream, carbon monoxide will bind to hemoglobin preferentially, reducing the amount of oxygen that can bind. This can lead to a condition called carbon monoxide poisoning, which can be life-threatening.

Which among these is not a GRANULOCYTE?
A.
Monocyte
B.
Neutrophil
C.
Basophil
D.
Eosinophil
Correct Answer
A. Monocyte
Explanation Monocytes are not considered granulocytes because they do not contain granules in their cytoplasm. Granulocytes, on the other hand, are a type of white blood cell that have granules in their cytoplasm. Neutrophils, basophils, and eosinophils are all examples of granulocytes as they contain specific granules that play a role in their immune functions. Monocytes, although they are also a type of white blood cell, do not possess these granules and are therefore not classified as granulocytes.

What type of cell is seen in the figure?
A.
Eukaryotic cell
B.
Prokaryotic cell
Correct Answer
B. Prokaryotic cell
Explanation The cell seen in the figure is a prokaryotic cell. This can be inferred because prokaryotic cells are characterized by the absence of a nucleus and membrane-bound organelles, and the figure shows a cell lacking these features. Prokaryotic cells are typically smaller and simpler in structure compared to eukaryotic cells, which have a nucleus and various organelles. Therefore, based on the information provided, the cell in the figure is most likely a prokaryotic cell.
Explanation MITOSIS is the process of cell division that occurs in somatic cells, which are any cells in the body other than reproductive cells. Similarly, MEIOSIS is the process of cell division that occurs in sex cells, also known as gametes or gametocytes. These sex cells are responsible for sexual reproduction and have half the number of chromosomes as somatic cells. Therefore, the analogy between MITOSIS and MEIOSIS is that they both involve cell division but in different types of cells.

A protozoan is observed to be moving towards the direction of a nutrient source. What process is exhibited?
Correct Answer positive chemotaxis
Explanation The observation of a protozoan moving towards a nutrient source indicates positive chemotaxis. Positive chemotaxis is a biological process where an organism moves towards a higher concentration of a particular chemical substance, in this case, the nutrient source. This behavior is commonly observed in single-celled organisms like protozoans, as they are able to detect and respond to chemical gradients in their environment. By moving towards the nutrient source, the protozoan increases its chances of obtaining the necessary nutrients for survival and growth.

With binomial nomenclature in mind, what does humanus represent in the scientific name Pediculus humanus?
A.
Species name
B.
Genus name
C.
Family
D.
Order
Correct Answer
A. Species name
Explanation In binomial nomenclature, the scientific name of an organism consists of two parts: the genus name and the species name. The genus name represents a group of closely related species, while the species name identifies a specific species within that genus. In the given scientific name "Pediculus humanus," "humanus" represents the species name, indicating a specific species of the genus Pediculus.

Which animal does not belong to phylum chordata?
A.
Alligator
B.
Ostrich
C.
Octopus
D.
Shark
Correct Answer
C. Octopus
Explanation The octopus does not belong to the phylum Chordata because it lacks a notochord, which is a defining characteristic of animals in this phylum. While alligator, ostrich, and shark are all members of the phylum Chordata, the octopus belongs to the phylum Mollusca. Mollusks, including octopuses, have a different body structure and are not classified as chordates.

How many heterozygous offspring(s) is/are produced in a cross between parents with the genotypes RR and rr, respectively?
A.
4
B.
3
C.
2
D.
1
Correct Answer
A. 4
Explanation When two parents with the genotypes RR and rr are crossed, all of their offspring will be heterozygous because they will inherit one allele from each parent. Since there are no other options given, the correct answer must be 4, indicating that all of the offspring will be heterozygous.

Fossils are DIRECT evidences of evolution.
A.
True
B.
False
Correct Answer
A. True
Explanation Fossils provide direct evidence of evolution because they are the preserved remains or traces of ancient organisms. By studying fossils, scientists can observe the changes in species over time, which supports the theory of evolution. Fossils also allow us to understand the history of life on Earth and how different species have evolved and adapted to their environments. Therefore, the statement that fossils are direct evidence of evolution is true.

This refers to an ecologically-productive habitat where saltwater and freshwater meet.
Correct Answer estuary, estuaries
Explanation An estuary is a habitat where saltwater and freshwater mix, creating a unique and productive environment. It is formed where a river meets the sea, resulting in a mixture of saltwater and freshwater. Estuaries are known for their high levels of biodiversity and serve as important breeding and feeding grounds for many species of fish, birds, and other wildlife. The mixing of saltwater and freshwater creates a dynamic ecosystem with fluctuating salinity levels, which supports a wide variety of plant and animal life. Estuaries also play a crucial role in filtering pollutants and sediment from the surrounding land, helping to maintain water quality.

Some disease-causing microorganisms are transfered from one location/host to another through other organisms that harbor them. How are these organisms called?
A.
Causative agents
B.
Vectors
C.
Scalars
D.
Biohazardous agents
Correct Answer
B. Vectors
Explanation Some disease-causing microorganisms are transferred from one location/host to another through other organisms that harbor them. These organisms are called vectors. Vectors can be insects, such as mosquitoes or ticks, or other animals, such as rodents. They act as carriers of the disease-causing microorganisms and can transmit them to humans or other animals when they bite or come into contact with them. Vectors play a crucial role in the spread of many infectious diseases, including malaria, dengue fever, and Lyme disease.

The Philippine eagle (Pithecophaga jefferyi) is an example of an ovoviviparous animal.
A.
True
B.
False
Correct Answer
B. False
Explanation The Philippine eagle is not an example of an ovoviviparous animal. Ovoviviparous animals are those that produce eggs that hatch inside the mother's body, and the young are born alive. However, the Philippine eagle is not ovoviviparous. Instead, it is a type of bird that lays eggs and the young hatch from those eggs outside of the mother's body. Therefore, the correct answer is false.

Which part of a plant cell is not found in an animal cell?
A.
Mitochondrion
B.
Cell membrane
C.
Cell wall
D.
Nucleus
Correct Answer
C. Cell wall
Explanation The cell wall is the correct answer because it is a rigid outer layer that provides structural support to plant cells, but it is not found in animal cells. Animal cells have a flexible cell membrane instead, which serves a similar function of enclosing and protecting the cell, but does not provide the same level of rigidity as a cell wall. The mitochondrion, cell membrane, and nucleus are all present in both plant and animal cells.
