The correct answer is D
Explanation:
A resting neuron has a voltage across its membrane, which is referred to as resting potential. This resting potential is caused by concentration gradients of ions across the membrane. A neuron returns to the threshold potential by the movement of positive ions (especially K+ ions) through channels that stay open to exit the neuron.

A change in the number of neutrons in an atom will change the isotope. What will happen when the
number of protons changes in an atom?
Answer:
A couple of things that will happen if you change the number of protons, electrons, and neutrons in an atom. If you change the number of protons in an atom somehow, then there will be less positive charge. If you change the number of neutrons somehow, nothing will happen because it carry's no charge at all.
Explanation:
Answer:
increasing the number of protons would increase the positive charge of the atom and that makes it an ion

Though energy cannot be created or destroyed, it can be transferred and transformed. When energy is not in use, it can be stored
Chemical energy is stored in chemical compounds and released through chemical reactions. Think about the ways you have used stored
chemical energy
Which are true statements about how chemical energy can be stored and released through chemical reactions?
Answer: The question is incomplete as the options are not given but the options is gotten from another websites.
1 .As bike tires roll across the sidewalk, friction is created and they become warmer.
2. Solar energy from the sun is absorbed by solar panels, which transforms to chemical energy when it is used as electricity.
3. As food is digested, molecule bonds are broken, allowing new molecules to form that can be used by our bodies.
4. Energy stored in organic fuels are used for heat and electricity/ When batteries are connected to a circuit, a reaction occurs inside the cell producing electrical energy.
5. Thermal energy causes energy stored in fireworks to convert to kinetic, light, and sound energy.
The correct options are 3 and 4.
3. As food is digested, molecule bonds are broken, allowing new molecules to form that can be used by our bodies.
4. Energy stored in organic fuels are used for heat and electricity/ When batteries are connected to a circuit, a reaction occurs inside the cell producing electrical energy.
Explanation:
Chemical energy is stored in food but when the food is broken down into smaller pieces or nutrients by the process of digestion, chemical energy are released which is use to drive different body functions or mechanisms.
Chemical energy are stored in circuits. When these circuits are connected to battery, the chemical energy are released and these energy are then converted to electrical energy to produce heat or light .

Identify the following text structure in the example below and choose the correct answer:
Attracted by the sweet nectar that each flower offers, the bees crawl around on the petals to find the perfect sucking position. As they do so, their furry bodies are dusted with beads of pollen. As they fly from blossom to blossom in search of more of the sweet energy drink, they transfer pollen from the male part of the flower to the female part, and so fertilize it. Not long afterwards, the plant's ovaries swell into fruit, which by late August turn into precious, oval-shaped nuts.

The earliest plants to appear on the earth, based on the fossil record, are _____. The first plants to grow on land were ______, which lack vascular tissue. _____ were the first group of land plants to evolve vascular tissue, allowing them to grow taller. The _____ group produces seeds that develop in cones, while the ______ group produces seeds that develop in fruit. Each of these groups of plants has a reproductive cycle that includes a ____ form that produces seeds or spores and a _____ form that produces sperm or eggs.
Answer: Cyanobacteria, bryophytes, Pteridophytes, Gymnosperms, Angiosperms, Sporophytic phase, and Gametophytic
Explanation:
Cyanobacteria or blue green algae were the first or earliest known plants which appeared on earth they performed the process of photosynthesis by using water and carbon dioxide in the atmosphere to produce oxygen gas. Bryophytes were the first land plants on earth including the mosses and liverworts, these plants did not had the vascular system and true roots, stems, and leaves. Pteridophytes are the plants that have vascular system. Gymnosperms are the plants that have naked ovules and the seeds are enclosed in the woody covering called cone. The angiosperms are the flowering plants, which develops seeds after fertilization gets enclosed in a fruit. The sporophytic phase, involves the development of a dominant sporophyte which produces spores which on germination produces a gametophytes which produces gametes (male and female) for fertilization.

They can live on land or
in water. B
They can bear extreme
temperatures.
C
They need comparatively
less food. D
They have a large number
of legs.
Answer:
Sorry, I don't know the answer, but I do know this:
Explanation:
Cold-blooded animals have resistance against microorganisms, and when they are infected, they reduce body temperature as a defense mechanism. Warm-blooded animals have a much stronger immune system to defend against such microorganisms. They gain energy in the form of heat to regulate body temperature for survival.
