Answer:
The correct answer is option c) Es un parásito.
Explanation:
The planarians are a group of "flat worms" that previously corresponded to the class Turbellaria, which is why they are also called as peat bogs. Around 4500 species are known, most of them aquatic in benthic ecosystems, although there are also species adapted to humid environments on land.
The vast majority of planarians are free-living animals, unlike the rest of flatworms that are totally parasitic. Most are aquatic and live in the bottoms (benthos) feeding on other small animals or on remains of decomposing organic matter.
Todas estas son características de las planarias excepto son parásitos (Opción c).
Los planáridos (Planariidae) son una familia de gusanos planos del phylum Platyhelminthes.Estos gusanos planos (planarias) son de vida libre, contrariamente a otros platelmintos que son generalmente parásitos.No obstante, es importante aclarar que existen excepciones a la regla y algunas especies de planarias son parásitas de diferentes animales.Algunos géneros de planaria incluyen:

What type of bonds do carbon atoms form?
The type of bonds that could be formed by carbon atoms should be various types of covalent bonds.
The covalent bond represents the chemical bond in which the pairs of the electron that lies between atoms should be shared.
Types of covalent bonds:
A single bond arises at the time when 2 electrons were shared in which there is the bond of one sigma lies between 2 atoms.The double bond arises at the time when 4 electrons were shared that lies between 2 atoms and contains 1 sigma bond + 1 pi bond.The triple bond arises at the time when 6 electrons were shared that lies between 2 atoms and contains 1 sigma bond + 2 pi bonds.The following information regarding covalent bond should be considered:
It can be an individual, double, or triple type of bond.In the case of an aromatic compound such as benzene so it creates the form that is treated to be effective lies between an individual & double that could vary approx 6-member carbon ring but normally overall 6 bonds should contain a similar length.Therefore we can conclude that The type of bonds that could be formed by carbon atoms should be various types of covalent bonds.

The diagram below shows three cubes. Which has the biggest surface area to volume ratio? 100 points if you answer
Answer:
2
Explanation:
The cube 2 has biggest surface area to volume ratio among diagram of three cubes.
What is surface area to volume ratio?The ratio of surface area of substance or object to the volume is called surface area to volume ratio.Let the length of the cube as X.
Then,surface area of cube = [tex]X^{2}[/tex]
Volume of the cube = [tex]X^{3}[/tex]
Surface area to volume ratio = [tex]X^{2}[/tex]/[tex]X^{3}[/tex] = 1/[tex]X^{}[/tex]
So, surface area to volume ratio is inversely proportional to the length of the cube.
So, larger the length of the cube smaller will be their surface area to volume ratio value.
Therefore, in the diagram the length of the 2 cube is minimum among three cubes.
Hence, cube 2 has biggest surface area to volume ratio

O grass
O mouse
O snake
O hawk
Answer:

Explanation:
it produces energy from the sun and gives that energy to all the other consumers that eats it
The producer in this food chain is grass, as it is the organism that produces its own food through photosynthesis.
What is a food chain?A food chain is a linear sequence of organisms in which each organism serves as a food source for the next organism in the chain. The organisms in a food chain are connected by their feeding relationships, with energy and nutrients passing from one organism to the next.
Producers are organisms that form the base of the food chain by converting sunlight into chemical energy through photosynthesis. These organisms are typically plants, algae, or certain types of bacteria. They are called producers because they produce their own food, using energy from the sun and inorganic nutrients from their surroundings. As a result, they are able to support all other levels of the food chain, including herbivores, carnivores, and omnivores.

A manager wanted to test whether the amount of noise in a clothing factory affected how
much work employees accomplished. Three groups of employees were tested every day
over a 5-day period. All three groups did the same type of work, they were all equally trained
to do the work, they used the same equipment, and they were tested the same time of day.
Group one was given headphones that blocked out all of the outside noise. Group two was
given headphones that blocked out some of the noise. Group three was not given anything
to block out the noise. The number of shirts made by the employees in one hour was
determined.
What is the dependent/responding variable?
The amount of noise.
O The number of shirts made by the employee.
O The type of music the employees listen to while they work.
O The amount of training employees need.
Answer:
When seeking to determine the number of shirts made by employees subjected to noise with and without the use of headphones, the dependent variable is the number of shirts made by the employee.
Explanation:
In a study or research, the dependent variable is the result of the intervention on the independent variable, which can be modified. In the case presented, the dependent variable is the quantity of shirts made by the employees, the number of which is measured at the end of the study.
It is expected that those employees who block the noise using headphones produce a greater number of shirts than those exposed totally or partially to noise.
For the other options:
The amount of noise. This can modified by the use or not of headphones and is the independent variable, subject to modification.The type of music the employees listen to while they work.

Several groups of researchers were conducting experiments to study how exercise affects cholesterol levels. One group had college students run two miles a day for six weeks. Another group had senior citizens participate in gentle water aerobics twice a week for a year. Cholesterol levels dropped slightly among the college students but dropped significantly among the senior citizens. Based on these results, what should the researchers plan to do next to validate the findings?
Answer:
Design more studies testing the effect of duration and intensity of exercise on cholesterol levels in different age groups.
Explanation:
Based on the result, the researcher will now see if the time duration of exercises will affect the cholesterol. So, now the time variables will be interchanged for the exercise.
What is an experiment?An experiment is a scientific procedure that makes a discovery based on the hypothesis and calculations and gave a fact or result. Experiments are done to prove the hypothesis.
Here, the experiment is to control cholesterol by exercise. Two variables are taken for experimentation, one is a senior citizen performing water aerobics and the second is college students performing running.
Thus, based on the findings, the researcher will now examine if the length of exercise sessions has an impact on cholesterol. Therefore, the exercise will now swap the time variables.

Explanation:
Just took the test on edge
In this three equations below, Nuclear fusion plays an important role in making elements that are heavier than helium. Hence option D is correct.
What is nuclear reaction ?There are two types of nuclear reactions. Nuclear fission and nuclear fusion.
Nuclear reactions are classified into two types: fission and fusion. Nuclear fusion is the collision of two or more light nuclei to produce a heavier nucleus. Nuclear fusion happens in low-atomic-number elements such as hydrogen. Nuclear fusion is the inverse of nuclear fission, in which heavy atoms scatter and lighter elements are produced. Nuclear fusion and fission both provide massive quantities of energy.
A nuclear process in which low-atomic-number atomic nuclei fuse to form a heavier nucleus, releasing energy.
Every star in the universe, including the sun, is alive because of nuclear fusion. As a result of this activity, they create enormous amounts of heat.
Fission is a nuclear phenomenon in which a heavy nucleus spontaneously fractures or collides with another particle, releasing energy. Nuclear fission happens when an atom's nucleus splits into lighter nuclei as a result of a nuclear process. This decay can occur naturally due to radioactive decay, or it can be mimicked in a laboratory by creating the necessary conditions (bombarding with neutrinos). The overall mass of the resulting fragments is less than that of the original. The missing mass is converted into nuclear energy in the preceding step.
hence option D is correct.

Functions were originally an idealization of how one variable depends on another. The concept of functions was formalized in set theory at the end of the 19th century, greatly expanding the scope of the concept.
Functions are also called maps or mappings, but some authors distinguish between “maps” and “functions”. A function's range or image is the set of images of all the elements in the range.

The cellular structure that perform the same function as lungs is mitochondria. The correct option is B.
What is mitochondria?Mitochondria are membrane-bound cell organelles that produce the majority of the chemical energy required to power the cell's biochemical reactions (mitochondrion, singular).
The Lungs of multicellular organisms, as defined on this question, are a breathing organ concerned with the intake of oxygen required for cell respiration and the expulsion of carbon dioxide from the body, a process known as gas exchange.
This gaseous exchange feature of the lungs is completed for the manner of breathing that is completed on the cell level by way of mitochondria.
Mitochondrion is an organelle in eukaryotic cells that is involved in cell respiration (launch of energy). The lungs exchange the gaseous reactants (oxygen) and products (carbon dioxide) of cell respiration.
