A. True
Plants are multicellular organisms that are most definitely living!
Answer:
Hubble’s law on distant red shift, the abundances of light elements, and the background radiation levels in the cosmos
Explanation:
Apex
B, They are both made of protons, neurons, and electrons
Explanation:
Nitrogen and oxygen are both gases at normal warmth and pressure. They are more both elements. They both dissolve at a really cold temperature.
They're the principal components of Earth's atmosphere.
They're both diatomic gases.
They're both nonmetals.
They're both light elements.
Both of them are involved in the CNO cycle.
B. mammary glands and hair or fur. things also to classify: feed milk to young, give birth live, and breathe in air, so they have lungs.
<h2>Membrane potential </h2>
Explanation:
- Membrane potential represents charge difference across the membrane, all biological cells are negative inside (cytoplasm) and positive outside (due to difference in ionic distribution)
- In a typical neuron cell membrane potential of cytoplasm is negative at rest (when no stimulus is applied) hence called resting membrane potential
- Resting membrane potential of excitable cells is established by Na+ and K+pump
- Repolarization starts with the efflux of K+ by the opening of voltage gated K+ channels
- Voltage gated K+ channels starts to open when voltage gated Na+ channels becomes inactive
- Hyperpolarization occurs due to excessive efflux of K+ by voltage gated K+ channels
- Additional efflux of K+ occurs due to slow inactivation of voltage gated K+ channels
