Answer: Option D.
radio waves, infrared light, visible light, ultraviolet light.
Explanation:
Radiant energy is energy electromagnetic radiation that travels by waves or particles. It is measure in Joule. There are different type of electromagnetic radiation and they are defined by the amount of energy, photons and wave lengths.
Radio waves have photons with low energies and wavelengths, microwaves have little, infrared waves have more than the two, ultraviolet have more, x rays have more energy photons and wavelengths, then gamma rays have more.

how does predation cause stability in an ecosystem
Answer:
Predation makes sure that no species becomes overpopulated.
Explanation:
For example, between a fox and a rabbit. If the fox was not the predator, the rabbit population would be out of control. Rabbits eat grass and stuff so too many rabbits will eat all the grass. There will be a chain effect. Foxes are needed to control the rabbit population and restore stability in an ecosystem
Question 1:
On the basis of these data, which group of robins most likely shares a most recent common ancestor
with the Norfolk Island robins?
Hello. You forgot to enter the necessary data for this question to be answered. The data are shown in the figure attached below:
Answer:
Red-capped Robin is the group of Robins that share a more recent common ancestor with the Norfolk Island robins.
Explanation:
Red-capped Robin is the group of Robins that share a more recent common ancestor with the Norfolk Island robins, this can be seen by the degree of genetic similarity between these two species, since the Red-capped Robin has 98.2% of genetic similarity .
When two species have the same common ancestor, these species have great genetic similarity and the more recent this ancestry is, the greater the genetic similarity between the species.
Beyond their role in energy transfer, what other benefit do microorganisms that act as producers provide for ecosystems?
How are microorganisms involved in the movement of nitrogen from the atmosphere to the bodies of other organisms? Why can’t other organisms just get nitrogen from the air?
What is the benefit of using marine microorganisms such as Dumaliella tertiolecta to produce biofuels instead of using plants?
Answer:
The microorganisms present metabolic wastes that serve as the primary source of food for other living things.
Bacteria that live free in the soil or in symbiosis with plants are essential to fix nitrogen, both nitrates and ammonia. These bacteria take nitrogen directly from the air, originating compounds that can be incorporated into the composition of the soil or living beings.
This property is restricted only to prokaryotes and is widely distributed among different groups of bacteria and some archaeobacteria. It is a process that consumes a lot of energy that occurs with the mediation of the enzyme nitrogenase, which the rest of the living organisms that cannot do or comply with this process is because they lack said enzyme.
Dunaliella is a genus of microscopic algae of the Chlorophyceae class and of the order Volvocales. All are unicellular, although with very varied morphologies.
Morphologically, its main characteristic is that they lack a rigid polysaccharide cell wall.
The ecology of this genus of green algae is characterized by its high tolerance to salinity, with eukaryotic organisms having greater tolerance to salt. They are euryhaline, adapted to salt concentrations from 50 mM NaCl to almost 5.5 M NaCl.
Explanation:
By nitrogen fixation is meant the combination of molecular nitrogen or dinitrogen with oxygen or hydrogen to give oxides or ammonia that can be incorporated into the biosphere. Molecular nitrogen, which is the majority component of the atmosphere, is inert and not directly usable by most living things. Nitrogen fixation can occur abiotic (without the intervention of living beings) or by the action of microorganisms (biological nitrogen fixation). Fixation in general involves the incorporation into the biosphere of a significant amount of nitrogen, which globally can reach about 250 million tons per year, of which 150 correspond to biological fixation.

Explanation:
Why is it more ethical to test for the waste products of respiration rather than the reactants
Answer:
The knowledge of simple biological reactions tells us that the product of reactions results from the complete or partial use of the reactants. In some reversible reactions, products can be converted to reactants in equal volume. Hence, in reactions that cannot be reversed, as evident in respiration, its waste products can be used to indicate that indeed respiration did take place. When glucose is consumed it is broken down through a series of reactions to give carbon dioxide and water as waste products.

A farmer has applied a pesticide to control a pest population that is affecting her crops. The pest population has reacted as shown below.
A chart begins with 4 green bugs and 1 brown bug. The brown bug survives and produces brown offspring.
Which best describes the process that the pest population has experienced due to this environmental change?
genetic diversity
natural selection
natural resistance
gene flow
The correct answer is option B. natural selection.
What is Natural Selection?Natural selection is a natural process in which well-adapted organisms tend to survive and reproduce more than less-adapted organisms. For example, tree frogs can be eaten by snakes and birds. This change means that some individuals have more environmentally-adapted traits than others, and their offspring are scarce. There is no doubt that natural selection has shaped the evolution of humankind in our farther past.
Natural selection is an inevitable result of three principles. Most traits are inherited, producing more offspring than can survive, and offspring with more favorable traits survive and have more offspring than individuals with less favorable traits.

Do you think Biotechnology can be used in anyway in a case where someone has been bit by a venomous snake? If so how?
Answer:
Snake biting is a major public health problem for low-income countries. Till now only antiserum derived from animals are use for the treatment against snakebite venom.
But there are many innovation in biotechnology to manufacture antivenoms against venomous snake. Some of the innovations are as following:
Use of DNA immunisation techniques: In this technique, horses are immunised with toxin-encoding DNA and then antivenom is prespraed from their DNA.Recombinant antivenoms: in this technique antibodies in the animal-derived antivenom are replaced with recombinant human version and then entivenom will be prepared by cell cultivation.These innovation in biotechnology for the preapartion of antivenoms are easier to produce and more cost-effective.

What are the three main properties of the atmosphere and how do they interact?
Answer:
The three properties of the atmosphere are temperature, air pressure, and humidity. Air pressure decreases with height because the mass of air above you decreases. The temperature varies, but it continues to increase near the end in the exosphere. Humidity is not directly affected by altitude
Hope it helps :)
Explanation:
What Is Air?
You probably don't think too much about air, but it's all around you. It takes up space and is pushing on you right now. There isn't air in space, and if you were to suddenly find yourself in the middle of space without a spacesuit, you'd be aware of how important air is to your survival. Obviously, you need the oxygen to breathe, but if there isn't any air to push on you, bad things start to happen. For starters, bubbles would form in your bodily fluids, and you would double in size. Yikes. Let's get a spacesuit on you ASAP!
So… what is air? Air is a mixture of gases, water vapor, and other substances, and it has specific properties, or characteristics.
Air is made up of gases
Air has mass
Air exerts pressure and has weight
Air can be compressed
Air is impacted by temperature
Wow, that's a lot of new terminology! Let's check out each point on that list.
Mass and Mixture of Gases
Mass is defined as how much stuff an object contains - and by stuff, I mean matter, like atoms and molecules. And even though you can't see it, air has a lot of atoms and molecules. Air is a gas (as opposed to a liquid or a solid) and contains about 78% nitrogen, 21% oxygen, and 1% argon. There are other trace gases in air, like helium, carbon dioxide, and neon, just to name a few.
Air also contains water vapor; the amount varies depending upon the location (think tropical, humid Hawaii versus the dry desert of Las Vegas). Finally, air contains other things, like dust, pollen, and bacteria.
What proof is there that air has mass? Well, if you blow up a balloon with air, the balloon expands. It's expanding due to the gases, water vapor and other materials that give air mass.
Pressure and Weight
Let's move on to pressure, or when something exerts a force on something else. All of those atoms and molecules we just mentioned are moving all around you. The pressure you're experiencing right now is due to all of those atoms and molecules bumping into you, as well as the weight of all of the air molecules and atoms above you.
And how do we know those atoms and molecules have weight? If you were to weigh an empty balloon and then fill it with air and reweigh it, you'd notice it gained weight. This is because, as long as there's gravity, everything with mass has weight (including air).
And here's a fun fact: at sea level all of the air above you exerts 14.7 pounds per square inch on your body (as well as everything around you). If you're below sea level, the number is greater (because you have more air pushing
