Answer:
True
Explanation:
Myelin is a lipid-rich (fatty) substance that surrounds nerve cell axons (the nervous system's "wires") to insulate them and increase the rate at which electrical impulses (called action potentials) are passed along the axon. In the CNS, axons carry electrical signals from one nerve cell body to another. ...

Do substances that dissolve in water pass through the plasma membrane
Solutes dissolved in water on either side of the cell membrane will tend to diffuse down their concentration gradients, but because most substances cannot pass freely through the lipid bilayer of the cell membrane, their movement is restricted to protein channels and specialized transport mechanisms in the membrane
what determines the primary structure of a protein?
Answer:
A protein's primary structure is defined solely by its amino acid sequence, and is constructred by peptide bonds between adjacent amino acid residues. Secondary structure results from hydrogen bonding along the polypeptide backbone, resulting in alpha-helices and beta-pleated sheets.
Bonds between atoms form and break during chemical reactions. Relate this forming and breaking of bonds to changes in energy.
Answer:
Explanation:
Energy is absorbed to break bonds. Bond-breaking is an endothermic process. ... Bond-making is an exothermic process. if a reaction is endothermic or exthermic depends on the difference between the energy needed to break bonds and the energy released when new bonds form.
In all types of chemical reactions, bonds are broken and reassembled to form new products.
In exothermic, endothermic and all chemical reactions it takes energy to break existing bonds and energy is released when the new bonds are formed.What is a chemical reactions?A chemical reaction is a process in which one or more substances, the reactant are converted into one or more different substances, the product.Substance are either chemical elements or compounds.To know more about chemical reaction here

Explanation:
Human caused climate change (most notably, global warming) has many positive feedback loops intrinsic to itself. Please describe at least one of these loops and explain how it is potentially dangerous for habitability of the earth.
When we burn fossil fuels to produce electricity, heat, and more, they emit greenhouse gases (GHGs) like carbon dioxide (CO2) and methane. These gases trap the sun’s energy in Earth’s atmosphere as heat. As more and more GHGs are released, more heat gets trapped and the planet warms up, disrupting the long-standing, delicate climate systems that have made life on Earth possible.
The stronger storms and longer droughts we see becoming a dangerous new normal are a direct result. But how these impacts play off each other is far more nuanced. In many cases, the wildfires or disappearing glaciers we see in the headlines have unseen knock-on effects that lead to, well, more wildfires and disappearing glaciers.

please help me
Answer:
ORDINARY LIGHT
Explanation:
Compound microscopes and electron microscopes have some similarities only light microscopes use light and lenses to magnify objects.
What are light microscopes?A light microscope is an apparatus or tool used in biology labs that employ visible light to find, magnify, and enlarge very minute things. Utilizing lenses, they concentrate light on the specimen, magnifying it to create a picture. In most cases, the specimen is positioned near the tiny lens. The types and quantity of lenses that make up the microscope have a significant impact on the microscopic magnification.
There are two types of microscopes based on the number of lenses used: simple light microscopes, which have low magnification due to the use of a single lens, and compound light microscopes, which have higher magnification than simple light microscopes due to the use of at least two sets of lenses an objective lens and an eyepiece.
The lenses are positioned such that they may bend light for effective picture magnification.
The light microscope's capacity to make a picture by focusing a beam of light through a tiny, transparent object is the foundation for how it works. The picture is then magnified for viewing through one or more lenses. The specimen's transparency makes it simple and quick for light to enter. Bacteria, cells, and other microbial particles can all be included in specimens.
Therefore, although compound microscopes and electron microscopes have some similarities only light microscopes use light and lenses to magnify objects.
