Answer:
D. nucleus is the answer
Answer:
the term is: gene flow
hopefully my answer helps! ♡
(if my answers helped you please tell me, therefore I know.. that I did them correctly or incorrectly. anyways, have a great day/night!)
Explanation:
gene flow in population genetics refers to the flow or movement of genetic material from one population to another.
B. evolutionary succession
C. primary succession
D. secondary succession
Answer:
answer, I guess, is C.primary succession
B. Physical change; physical property of flammability
C. Chemical change; chemical property of reactivity
D. Chemical change; chemical property of flammability
Answer:
C = chemical change, chemical property of reactivity.
Explanation:
Chemical change:
The changes, that occur due to change in the composition of a substance and result in a different compound is known as chemical change.
These changes are irreversible
These changes occur due to chemical reactions
These may not be observed with naked eye
Example:
The reaction of iron with air in the presence of water lead to the production if ion oxide which is called rusting. It is a chemical change.
Combustion of fuel or wood: that oil or wood convert into energy, CO2 and ash in case of wood
Boiling of egg: that change the chemical composition of protein in the egg
The reaction of Hydrogen and oxygen:
H 2 (g) + O 2 (g) -------------------------------------> 2H 2O (l)
Physical Change:
The changes that occur only due to change in shape or form but their chemical or internal composition remain unchanged.
These changes were reversible.
They have same chemical property.
These changes can be observed with naked eye.
Example
Water converting to Ice
Water converting to gas
In this water molecule remain the same only they rearrange themselves that change its state of mater not composition
Answer:
C) Chemical Change; Chemical Property of reactivity
Explanation:
I took the test
Answer:
Habitat:
Habitat may be defined as the particular area occupied by the organism. Habitat involves the physical activity performed by the organism in its area. Habitat only reflects the living place of the organism. Habitat explains where the species live in the ecosystem.
Niche:
Niche may be defined as the role of the individual organism in its ecosystem. The function or the physiological activity of the organism in the area describes the niche. The association of the organism with the biotic and abiotic component to obtain food is included in niche. Niches explains the way by which organism live in an ecosystem.
Habitat is a place in which an animals lives
A niche is the organisms place or job in the environment
