Smooth muscles depolarize as a result of a transmembrane current of Calcium ions. When an action potential depolarizes the muscle cell membrane, it also travels into the body of the cell via the t-tubules. Unlike skeletal muscle, smooth muscle is dependent in two sources of calcium in order to intiate contraction. These two sources are calcium sequestered in the S.R. of the smooth muscle cell.
QUESTION:-
What is the maximum number of electrons that can be placed in the first shell/energy level?
A. 1
B. 8
C. 2
D. 18
Answer:
C. 2
The first shell, closest to the nucleus and with the lowest-energy electrons, is shell 1. This first shell has only one subshell (labeled 1s) and can hold a maximum of 2 electrons
Enzymes are proteins
protein synthesis ocurs in the ribosomes
The electrons surrounding an atom are located in regions around the nucleus called “energy levels”. An energy level represents the 3-dimensional space surrounding the nucleus where electrons are most likely to be. The first energy level is closest to the nucleus.
Answer;
Rewilding is the process of introducing genes of ancient plants into modern species.
Explanation;
-Rewilding is a progressive approach to conservation. It involves allowing the nature to take care of itself, enabling natural processes to shape land and sea, repair damaged ecosystems and restore degraded landscapes.
Through rewilding, wildlife's natural rhythms create wilder, more biodiverse habitats.
