Aside from solar energy, what else could provide electrons?
Electrical energy is delivered by tiny charged particles called electrons, typically moving through a wire. Lightning is an example of electrical energy in nature.
Small charged particles called electrons, which normally flow via a wire, provide electrical energy. An illustration of electrical energy in nature is lightning.
What are the different sources of electron?The majority of free electrons are created with minimal kinetic energy and just disperse through the atmosphere, participating in the random thermal motion of every atom.
With enough kinetic energy, some free electrons are created that can lead to further ionization and excitation.
The source of electrons is a filament, or cathode. Usually, it is a tungsten wire in the form of a hairpin.
The surrounding cathode cap is given an accelerating voltage (determined quantity of negative high voltage). The filament is then exposed to a tiny emission current to liberate electrons.
Therefore, aside from solar energy, electron are produce.

I found this i hope it helps
About the Heart and Circulatory System
The circulatory system is composed of the heart and blood vessels, including arteries, veins, and capillaries. Our bodies actually have two circulatory systems: The pulmonary circulation is a short loop from the heart to the lungs and back again, and the systemic circulation (the system we usually think of as our circulatory system) sends blood from the heart to all the other parts of our bodies and back again.
What characteristics apply to gymnosperms? (Choose all that apply)
use seeds to reproduce
use spores to reproduce
have vascular tissue
have cones as reproductive structures
Answer:
Have cones as reproductive structures.
Have vascular tissue.
Explanation:
The gymnosperms have vascular tissue and have cones as reproductive structures.
What are gymnosperms?The gymnosperms are woody like plants having a cone shaped structure, bear no flowers, no fruits but bear seeds; The seeds are with out coat and they are not covered by the fruit wall.
Gymnosperms produce seeds which are not enclosed in an ovary, while in Angiosperms the reproductive organs are the flower, they may involve in double fertilization resulting in a diploid zygote, and a triploid endosperm.
Gymnosperms produce seeds and fruits from their flowers, the flowers in gymnosperms helped in the propagation of the plants, it attract pollinators and attracted seed to dispersers, gymnosperms became dominant among plants.
The modification of the gymnosperm includes Modified leaves, Sunken stomata, Pointed and thick cuticle leaves, Less transpiration rate.

Answer:
Polar
Explanation:
In a water molecule, the oxygen atom is bigger and has a greater pull on the electrons than the hydrogen atoms do. This makes the molecule polar.
When a person eats the yogurt, the 14 grams of protein will be A combined into monosaccharides. B combined into polysaccharides. C broken down into amino acids. D broken down into nucleic acids.
Answer:
C broken down into amino acids.
Explanation:
Proteins are one of the four major biological molecules. They are organic polymers made up of monomers called AMINO ACIDS. Proteins are contained in food we ingest and are subsequently digested or broken down into their amino acid components.
In this case, when a person eats yogurt (containing proteins), the 14 grams of protein will be broken down into amino acids during digestion by enzymes called PROTEASES. Note that every polymer will be broken down into its monomeric constituents during digestion.
If energy is released, free energy must be what?
Answer:
If energy is released during a chemical reaction, then the change in free energy from the conversion of the reactants to the products, signified as ΔG (delta G) will be a negative number.
Explanation:
Hope it helped!
Answer:
If energy is released during a chemical reaction, then the resulting value from the above equation will be a negative number. In other words, reactions that release energy have a ∆G < 0. A negative ∆G also means that the products of the reaction have less free energy than the reactants because they gave off some free energy during the reaction.

4. Which of the following statements best describes how proteins and enzymes move within a cell?
The movement of proteins and enzymes within a cell is facilitated by intracellular receptors.
The movement of proteins and enzymes within a cell is facilitated by special organelles called transport receptors.
The movement of proteins and enzymes within a cell is facilitated by special organelles called magneto receptors.
The movement of proteins and enzymes within a cell is facilitated by membrane receptors.
Answer:
The movement of proteins and enzymes within a cell is facilitated by intracellular receptors.
Explanation:
Proteins and enzymes (which also are proteins) move inside the cell through intracellular receptors. These receptors are proteins capable of binding other molecules such as proteins and hormones in order to transport them to different cellular locations. Thus, intracellular receptors are key players in signaling pathways that trigger signaling events to regulate a particular function, for example, activating gene expression by transporting proteins to the nucleus.
In your own words describe how genetic diversity is increased through the processes of crossing over, independent assortment, and random sexual reproduction.
Answer: Genetic variation describes naturally occurring genetic differences among individuals of the same species. Gene duplication, mutation, or other processes can produce new genes and alleles and increase genetic variation. New genetic variation can be created within generations in a population, so a population with rapid reproduction rates will probably have high genetic variation. And there are the reasons.
Give an example of how Eubacteria can be beneficial. Explain. Please help me.
Answer:
Some bacteria are good for you, including the bacteria in your digestive system, or gut. These bacteria help to break down food and keep you healthy. Other good bacteria can produce oxygen are used to create antibiotics. Bacteria are used in food production to make yogurt and fermented foods.
An example of how Eubacteria can be beneficial is that these bacteria fix nitrogen for soil that can be used by living beings.
What are eubacteria?The bacteria in your gut and digestive tract are among the beneficial bacteria. These microorganisms aid in the digestion of food and promote good health. To make antibiotics, other beneficial microorganisms that can also produce oxygen are employed. Yogurt and other fermented foods are produced using bacteria in the food industry.
Oxygen, carbon, nitrogen, and phosphorus that living things like animals and plants cannot use can be converted by eubacteria into usable forms. In the soil, they fix the nitrogen that is present in the air.
Therefore, Eubacteria can help the environment by fixing nitrogen into the soil so that living things can use it.

Traditionally most units of time are based upon a)the motions of earth, b)the longitude of an observer, c)the motions of the moon, or d)the real motions of the sun
Answer:
The correct answer is option A (the motions of Earth).
Explanation:
The word "Time" may have different meanings, "Time" in a simple term, it is used to measure events, and it is the bedrock that is used to determine seasons. Time is measured in seconds, minutes, hours, days, weeks, months, years. Unlike clocks, and other different devices used to measure time, these devices were not available some centuries ago. So, time was measured in those centuries with the help of the knowledge of the rising and setting of the sun which are caused by the rotation of the Earth. The most standard unit of time used this day are all products of research Astronomers were able to do through studying the motions of the Earth. For instance, when the Earth makes a full rotation around its own axis, that signifies a day, which is a period of about 24hours. considering we have leap years, so it is not complete 24 hours.

How is biodiversity regulated in a system?
Answer & Explanation:
Biodiversity is regulated primarily by weather in addition to many other factors. Weather changes can cause droughts or flooding. Weather often pushes main species to migrate and therefore cause new biodiversity, indirectly the migration of one species into a new region could cause that new species to consume the already thriving species already in existence which then could reduce the value of species diversity in that region and throw off the pre-existing ecosystem.
