What is a herbivore?
A. an animal that gets energy from eating other animals
B. an organism that gets energy from eating only plants
C. an animal that gets energy by eating both plants and other animals
D. an animal that eats only herbs
An herbivore is an animal or organism that gets energy from eating only plants, which is present in option B. Examples are the goat, cow, etc., and they eat the producers, such as the plants.
What is the role of the herbivore?The herbivore is the animal that directly eats the plants of the ecosystem, which are later eaten up by the carnivore, and the herbivore gets more energy than the carnivore as they get energy directly from the plant source. The herbivore only eats plants, and the different ecosystems have different herbivores, such as the land ecosystem, which has the goat, elephant, cow, etc.
Hence, an herbivore is an animal or organism that gets energy from eating only plants, which is present in option B. Examples are the goat, cow, etc., and they eat the producers, such as the plants.

Which of these is a form of nonrenewable energy?
O A. Fossil fuel energy
O B. Solar energy
C. Wind energy
O D. Hydroelectric energy
Answer:
Fossil fuel energy
Explanation:
This is because oil from fossils take a millions of years to form and people won't be able to wait millions of years
Fossil fuel energy is a form of non-renewable form of energy. Thus, the correct option will be A.
What is Non-renewable energy?A non-renewable energy resource is a natural resource which cannot be readily replaced by the natural means at a particular pace which is quick enough to keep up with the consumption of the energy resource. An example of the non-renewable energy resource is a carbon-based fossil fuel. The original organic matter with the aid of heat energy and pressure generally becomes a fuel such as the oil or natural gas.
There are four major types of the nonrenewable resources which include oil, natural gas, coal, and the nuclear energy. Oil, natural gas, and coal are collectively known as the fossil fuels. Fossil fuels were formed within the Earth from the dead plants and animals over a period of millions of years and hence are named as the fossil fuels.
Therefore, the correct option will be A.

The picture shows a contractile vacuole of a unicellular freshwater organism. The contractile vacuole regulates the flow of water into and out of the cell in an aquatic environement. What condtions cause the contracile vacuole to fill with water? Your answer: A.The concentration of water is greater outside the cell than inside the cell. B.The concentration of water inside the cell is the same as the concentration outside the cell. C.The temperature of water in the vacuole is higher than the temperature of its environment.
Answer:
A. The concentration of water is greater outside the cell than inside the cell.
Explanation:
This is a question having to do with tonicity, or the concentrations of solutes or solvents across a membrane. In these conditions, there is a hypotonic solution inside the cell (hypo means low, because there's less water inside), which will cause water to come inside.
The contractile vacuole stops the cell from exploding by regulating the amount of water that can come in. Otherwise, it would lyse, or split open.

Answer:
Alternate form of gene
Explanation:
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent.
Answer:
its D Alternate form of gene
What are the pros and cons of having the digestion be slower and over distance, as opposed to being quicker and over shorter distance with slightly less absorption?(40 points)
Answer:
Explanation: When you have a slow digestive system, a condition known as gastroparesis or delayed stomach emptying, these muscles don't work properly. They either contact too slowly or don't work at all and, as a result, your stomach doesn't empty properly.
Eating slowly also helps our digestion. Think of digestion as a chain reaction. As soon as we see, smell, or think about food (step 1), we start salivating to prepare for putting that food in our mouth (step 2). Saliva contains enzymes that break the food down, and moistens the mouth for easier swallowing.

Which option describes cations?
Answer:
D
Explanation:
A cation is a positively charge ion, such as a sodium ion, as when it becomes an ion, it gives away electrons, becoming positively charged.
The opposite is an anion, which is a negatively charged ion, such as oxygen as it receives elections from the cation when forming an ionic bond.
Cations are the positively charged ions.
What are cations?A cation has more protons than electrons, consequently giving it a net positive charge. For a cation to form, one or more electrons must be lost, typically pulled away by atoms with a stronger affinity for them.
The number of electrons lost, and so the charge of the ion, is indicated after the chemical symbol, e.g. silver (Ag) loses one electron to become Ag+, whilst zinc (Zn) loses two electrons to become Zn2+.
In contrast, most nonmetallic atoms have a stronger attraction to electrons than do metallic atoms, and as a result, they gain electrons to form anions.
Therefore, Cations are the positively charged ions.
