- Homo erectus
- Australopithecus africanus
- Pan troglodytes
- Homo sapiens
- d
-
The scientific name is given using binomial nomenclature (two words: genus and species).
Humans belong to the genus Homo and the species sapiens, so the scientific name is Homo sapiens.

Meiosis is not involved?
- Growth of body cells
- Genetic variation
- Sexual reproduction
- Formation of gametes
- a
-
Growth of body cells happens by mitosis, not meiosis.
Meiosis is a special type of cell division that makes gametes (sperm and eggs) and creates genetic variation.
Hydra, sea anemone & corals occur only as:
- Medusa form
- Spicules
- Polyp form
- Sycon form
- c
The magneto tactic bacteria detects earths magnetic field using magnets formed from an element crystals within their cytoplasm. The element is:
- Iron
- Potassium
- Sodium
- Calcium
- a
-
Magnetotactic bacteria can sense Earth's magnetic field.
Potassium, Sodium and Calcium are important for cells not for magnetic sensing.
Non-hyphal unicellular fungi are:
- Mushrooms
- Puff balls
- Slime molds
- Yeast
- d
-
Yeast is single cellular and used in baking.
Mushrooms and Puff balls are multicullular.
Slime molds are not fungi and have complex structure.
Cloning is the production of duplicate copies of genetic material (cells or entire multi-cellular organism) occurs naturally in plants and animals. For example:
- Vaccination
- Identical twins or triplets
- Phyletic lineage
- Deforestation & Industrialization
- b
-
Vaccination prevents from diseases, not cloning.
Phyletic Lineage is a evalutionary history, not cloning.
Deforestation & Industrialization is a human activity, not cloning.
Protests are:
- Prokaryotes
- Eukaryotes
- Hormones
- Coenobium
- b
-
Prokaryotes are not bacteria.
A small group of algae cells (tiny water plants) living together
Hormones is a chemical message.
The cleavage means:
- The structure of DNA
- Sequence of mitotic division
- Hollow sac having an opening
- Eukaryotes
- b
-
Cleavage means rapid repeated mitotic (cell) divisions of the zygote after fertilization.
The structure of DNA is not cleavage.
Eukaryotes is a type of organism.
The Cephalopods belong to the phylum:
- Platyhelminthes
- Nematode
- Porifera
- Mollucsa
- d
-
Cephalopods is like octopus, squid, cuttlefish.
The single cell formed after fertilization is called:
- An Embrye
- A Gamete
- A Foetus
- A Zygote
- d
-
After fertilization, when the male gamete (sperm) and female gamete (egg) fuse, they form a single cell called a zygote. This zygote is the first cell of a new organism and later develops into an embryo and then a foetus.
