Answer:
Competition
Explanation:
Predation refers to one animal killing & eating the other animal. Eg, as referred - tiger & deer (former eats latter)
Competition is when an organism competes with another for resources. Eg, as given - paddy & weeds (they compete for growth resources - like nutrients etc).
Answer:
Option (B).
Explanation:
Neurons or nerve cell are the basic structural and functional unit of the nervous system. Fibers are the thread like long projection of the nerve cells.
Neurons are classified into three fibers- Group A fibers, B fibers and C fibers. The group C fibers cannot capable of doing the saltatory conduction of the nerve impulse because they are unmyelinated.
Thus, the correct answer is option (B).
Appalachian: A. Two continents colliding.
The Appalachian mountain range is an ancient example of a collision between two continental plates. Both plates have low density and little subduction occurs between them.
North American Cordillera: B. Terrane accretion
These form when two continents that collided bonded so tight that it forms a permanent land mass. If the continents would pull away from each other, the terrane stays intact.
Aleutian plate: D. Oceanic convergence
This is a type of convergence where one plate subducts beneath another plate. Between the two, the older plate is usually the one that subducts because it is usually more dense.
Andes mountain range: C. An oceanic plate and continental plate colliding.
In the collision between an oceanic and continental plate, the thinner and more dense oceanic plate subducts under the continental plate. The Andes mountain range was formed by the subduction of the Nazca Plate beneath the South american Plate.
Answer:
DNA is considered to essential be the “instructions” or “blueprints” of life because it contains the code for the proteins that give you your traits.
Answer:
A, a prokaryotic cell
Explanation:
Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages.
