Answer:
A
Explanation:
Primary productivity, in ecology, the rate at which energy is converted to organic substances by photosynthetic producers.
Answer:
C, D, A, B, E
Explanation:
The sudden decrease or increase in the potential of cell membrane is Action potential. The stimulus (local current) allows change in the membrane potential, thus allowing depolarization of the membrane. This initiates the opening of Voltage Gated Na+ channels. The sodium starts entering the cell that is influx of Na+ and thus AP generated in adjacent axon segment. The sodium channels inactivates by membrane repolarization and activated pottassium channels allows the efflux of pottassium ions. The inactivation of potassium channels occurs by hyperpolarization ( low membrane potential) brings the membrane to its resting state. Thus, the correct order is C, D, A, B, E.
Answer:
Blue Eyes Are: Recessive
Explanation:
The brown eye form of the eye colour gene (or allele) is dominant, whereas the blue eye allele is recessive. If both parents have brown eyes yet carry the allele for blue eyes, a quarter of the children will have blue eyes, and three quarters will have brown eyes. I hope this helps :) Good luck on your assignment!!!
the second one, "using the scientific method makes it easier for scientists to share their results"
Explanation:
all of the other answers are correct do therefore I used the process of elimination, also, scientists sharing their results is the 7th step to the scientific method, it is not the targeted end result
I believe the correct answer is A) Silurian period occurred before the Neogene era, because the other answer are wrong.
Hadean eon ended before Silurian period.
Mesozoic and Permian era were after Silurian period.
