C:Culturales
D: Naturales
Los elementos que se refieren a las personas que conviven o trabajan prestando sus servicios en un espacio turístico, rural o en una cuidad , son los elementos económicos.
Por lo tanto, la respuesta es A) Económicos.Son económicos porque esas personas trabajan en el sector turístico rural o citadino.Eso significa que su trabajo genera un ingreso y produce un pago como retribución a su salario.El sector turístico mueve mucho dinero y es un gran generador de impuestos para el Estado.Por esa razón lo consideramos un elemento económico.Podemos concluir que -a pesar de que se te olvidó incluir la imagen a la que se refiere la pregunta- el turismo es una de las principales actividades económicas de un país
El turismo es una actividad que permite el ingreso de millones de dólares a través de los turistas que visitan una nación.

What are Amino acids? How are they bound?
Explanation:
Amino acids are organic compounds that contain amino and carboxyl functional groups, along with a side chain specific to each amino acid. The key elements of an amino acid are carbon, hydrogen, oxygen, and nitrogen, although other elements are found in the side chains of certain amino acids
Each amino acid is attached to another amino acid by a covalent bond, known as a peptide bond. When two amino acids are covalently attached by a peptide bond, the carboxyl group of one amino acid and the amino group of the incoming amino acid combine and release a molecule of water.

4. Estimate the size of the outlined (yellow) onion cell under high power (40x). Use the dFOV values calculated from question no. 3. 10 points
The following formula is useful to determine the size of the cell ⇒ Size of the object = FOV / Fit number = dFOV / Fit number. If you have this data, you can estimate the size of the onion cell. According to the values we used, the estimated size of this onion cell is 112 μm.
-----------------------------------------------
Cells are too small to measure their sizes, so to know their actual size, we can make mathematical estimations to know their sizes, or we can use software programs. In this case, we are estimating their size using the following formula,
Size of the object = FOV / Fit number = dFOV / Fit number
Size of the object = size of the cellFOV = eyepiece (mm)/objective magnification Fit number = The number of times the object -cell- fits in the field of viewTo answer this question, we will replace the terms in the given formula.
→ First, we will get the FOV value. From references, we can assume that
under 4X ⇒ FOV = 4.5 mmunder 10X ⇒ FOV = 1.8 mmunder 40X ⇒ FOV = 0.45 mmYou can also calculate the FOV by using a millimeter paper or rule.
Note: We will use these values to replace terms in the formula, but you can use the dFOV value calculated in question no. 3.
→ Second, we will count the number of cells that fit the field. We can see about four cells across the field of view.
→ Finally, we will replace the terms in the formula.
Size of the object = FOV / Fit number
Size of the object = 0.45 mm / 4
Size of the object = 0.112 mm
Since we generally use μm when referring to cell sizes, we need to multiply 0.112 x 1000 to get the size of the cell expressed in μm.
Size of the cell (μm) = 0.112 mm x 1000 = 112 μm

Explain why the red blood cells burst.
Answer:
red blood cells burst.
Explanation:
Red blood cells placed in a solution with a higher water concentration compared to their contents (eg pure water) will gain water by osmosis, swell up and burst. Water will diffuse from a higher water concentration outside the cell to a lower water concentration inside the cell.

anabolic metabolism is most similar to:
a. a car crashing into a wall at high speed
b. asexual reproduction in amoebas
c. a pump pushing water through a pipe
d. building a house of bricks
Answer:
Metabolism is defined as all the various processes in the body, which yield energy for the proper functioning of the organs and body. metabolism can be categorized into anabolism and catabolism. The correct option is building a house of bricks.
Explanation:
Anabolism is defined as the ‘building up’ of compounds, molecules, or other substances. The example that best explains anabolism is building a house of bricks. Anabolism is the synthesis of complex substances from simpler or monomeric units. Anabolism is termed as constructive metabolism, such that the complex molecules formed from simple molecules have stored form of energy.
A car crashing into a wall at high speed determines the breakdown of resources, such as walls, bricks, and cars. The crashing of the car can resemble catabolism, which is defined as the breakdown of complex substances into smaller substances.
Asexual reproduction is a biological process in which offspring are clone to the parent cell. In amoeba, the parent cell splits into two daughter cells, which have the same genetic information as the parent cell. The splitting of the parent into daughter cells is termed binary fission. The process resembles catabolism.
The pump pushing the water from a pipe is a type of example of pressure difference. The water flows from high pressure to low pressure, which results in the pushing of water out of the pipe. Thus, the activity does not exhibit any type of metabolism.
