Answer:
y=10
Explanation:
Given the expression 7 - y = -3
First we have to collect all constant term to one side hence
7+3-y=0
10-y=0
10=y
y=10

Explanation:
maybe I think true since different types of plants have different structures and because of the structures maybe a plant can reproduce like for a long time later and another plant can have a different structure and reproduce faster. I’m just 11
Answer: i would say D but i'm not entirely positive
Explanation:
this is showing how the energy is distributed between the types of organisms in an environment
I think Autorhythmic fibers are fibers that are self excitable or on their own for example some cardiac muscle. They repeatedly generate action potentials that trigger heart contractions.They continue to stimulate a heart to beat even when it is removed from the body. In comparison to contractile fibers, autorhythmic fibers are self excitable and do not require nervous system stimulation to trigger contractions. Contractile fibers have stable resting membrane potentials of -90mV, when a contractile fibers reaches threshold by action potential, the voltage gated fast sodium ions channels will open.
