Question 1
In evolution, analogous structures are significant because they
show
Options
A) physiological
diversity
B) functional
diversity
C) genetic
diversity
D) structural
diversity
The correct answer is
A.
Explanation:
In evolutionary biology, the term analogous structures pertains to the various
structures in different species having the same function but have evolved separately,
thus do not
share a common ancestor. In comparison, the homologous structures pertain to the
structures that show similar morphology and anatomy but have different functions.
Moreover, the homologous structures are believed to have evolved from a common
ancestor since they show similar development patterns during embryonic development.
Question 2
Which of the following statements reflects the mechanism of natural
selection?
Options
- A) There are variations within every
species
B) Individuals of every species are genetically
identical
C) No organism in a species dies before sexual
maturity
D) Organisms with selective advantages are less likely to
survive
The correct answer is A.
Explanation: Natural selection is the process whereby organisms better
adapted to their environment tend to survive and produce more offspring. The theory
of its action was first fully expounded by Charles Darwin, and it is now regarded as
the main process that brings about evolution.
Question 3
Which of the following animals exhibits
territoriality?
Options
A)
Rabbit
B)
Earthworm
C)
Lizard
D)
Toad
The correct answer is C.
Explanation:
Territoriality is a type of intraspecific or interspecific competition that results from the
behavioral exclusion of others from a specific space that is defended as territory.
This well-defined behavior is exhibited through songs and calls, intimidation
behavior, attack and chase, and marking with scents.
Question 4:
The branch of Biology that deals with the principles of classification of organisms is known as
Options
- A) biological
index
B)
nomenclature
C)
taxonomy
D)
ecology
The correct answer is
Explanation
:
Taxonomy is the science of defining groups of biological organisms on the basis
of shared characteristics and giving names to those groups.
Question 5
Which of the following structures is a
tissue
Options
A) Vessel
element
B)
Blood
C) Sieve tube
element
D)
Erythrocyte
The correct answer is B.
Explanation:
In biology, tissue is a cellular organizational level intermediate between cells and
a complete organ. A tissue is an ensemble of similar cells from the same origin
that together carry out a specific function. Organs are then formed by the
functional grouping together of multiple tissues.
Question 6
Which of the following cells are not regarded as
specialized?
Options
- A) Sperm
cells
B) Root up
cells
C) Muscle
cells
D) Somatic
cells
The correct answer is D.
Explanation:
Some cells in multicellular organisms are modified to carry out a particular function,
such as transporting a certain substance or executing a specific task. These cells are
called specialized cells. A somatic or vegetal cell is any biological cell forming the
body of an organism; that is, in a multicellular organism, any cell other than a
gamete, germ cell, gametocyte, or undifferentiated stem cell.
Question 7
Which of the following pairs of cells carry out the same
function?
Options
- A) Check cell and red blood
cell
B) Spermatozoon and
ovum
C) Palisade cell and epidermal
cell
D) Root tip cell and guard
cell
The correct answer is B.
Explanation:
A spermatozoon is a motile sperm cell or moving form of the haploid cell that is the
male gamete. A spermatozoon joins an ovum to form a zygote. A zygote is a single
cell, with a complete set of chromosomes, that normally develops into an embryo.
The egg cell, or ovum, is the female reproductive cell gamete in oogamous
organisms. The egg cell is typically not capable of active movement, and it is much
larger (visible to the naked eye) than the motile sperm cells. When egg and sperm
fuse, a diploid cell (the zygote) is formed, which rapidly grows into a new organism.
Question 8
