Answer:
1° Somos los residuos y venimos de todas partes del cuerpo. 2° Ahora vamos a pasar por el riñón, que hace las veces de filtro. 3° Vamos ahora por el uréter. 4°Llegamos a la vejiga 5° Es hora de ir al baño, pasemos a la uretra 6° Cuando nos vayamos la sangre quedará limpia.
Explanation:
La sangre para deshacerse de las toxinas, desechos y excesos de elementos viaja a los riñones donde es filtrada, Allí, la sangre se deshace de todos los elementos que el cuerpo y esta ya no necesita y forma la orina. La orina, al ser los desechos del cuerpo van a viajar por medio de unos conductos llamados uréteres a la vejiga. Una vez que esta se llena, la orina pasa por la uretra, la cual es otro conducto que lleva la orina fuera del cuerpo en la micción.

A).blood
B).brain
C.)eye
D.)leukocyte
E.)muscle
Among the listed components, the brain and the eye are the organs. Skeletal muscles are also classified as organs.
What are the levels of the organization?In anatomical studies of an individual, the classification of the hierarchy of the structures of the organism is useful for the estimation of the complexity level of the individual.
The chemical level of organization is the first level of organization where atoms are combined for the formation of molecules. Molecules are combined to form macromolecules.
Different types of macromolecules result in the cellular level of organization. The macromolecules that are the components of cells are called biomolecules.
Cells of the same kind are combined and work in the association as a tissue, for example, nerve cells form nerve tissue.
These tissues of similar functions combine to form organs. For example, multiple nerve tissues are combined to form the brain and the spinal cord.
The nerve cells, nerve tissues, spinal cord, and brain are studied together as an organ system called the nervous system. Several organ systems like this are grouped to form an individual.
Therefore, the brain and eye are examples of organs.

Why do we cook our food and put lime on fish / shrimp to make ceviche
Answer:
The reason is because ceviche (sev-ee-chay) is still very much raw fish or seafood.
The citrus bath the seafood sits in does turn the meat opaque, giving it the appearance of being cooked, and it does kill some of the many wee beasties present in raw foods that can make you sick, notably the toxin vibrio.

The diagram shows molecules that a mitochondrion and produces during a cellular process. Which other molecules is a product of this process?
A. DNA
B. RNA
C. C6H1206 (glucose)
D. ATP
Answer:D
Explanation: DNA and RNA are held in the nucleus and have nothing to do with what is shown in the image which is the process of cellular respiration. What is fascinating is that the mitochondrion has its own DNA but it does not produce it in a cellular process. C is false because the mitochondrion takes in glucose so it will go alongside the pyruvate O2. So we can conclude that it produces ATP with H2O and CO2 during this process.
ATP molecule is also a product of the cellular process that occurs in the mitochondria.
MITOCHONDRIA:
The mitochondrion is a membrane bound organelle found in eukaryotic cells. The mitochondrion is regarded as the power house of a cell because it is the site of the cellular process that synthesizes energy for the cell.The cellular process that occurs in the mitochondria is called cellular respiration. Generally, cellular respiration breaks down glucose molecule in the presence of oxygen. The chemical equation is as follows:C6H12O6 (glucose) + 6O2 (oxygen) → 6CO2 (carbon dioxide) + 6H2O (water) + ATP (energy)
From the attached image, it can be seen that water (H20) and carbon dioxide (CO2) are products. However, ATP molecules is also synthesized during this cellular process. Therefore, ATP molecule is also a product of the cellular process that occurs in the mitochondria.Learn more: https://brainly.com/question/23126016?referrer=searchResults

What is a rule for making a neutral atom which has no charge?
The rule for making a neutral atom that has no charge is - Electron (E) = Proton (Protons).
Neutral atoms are atoms that have no charge or zero charges. It is known that an atom has three sub-atomic particles; Proton, Neutron, and electrons. Protons have a positive charge, neutrons have zero or no charges and electrons have negative charges.
There are three conditions possible:
The neutral atom that has no charge - The number of electrons and protons must be the same.E = P
A positive ion that has a positive charge - The number of protons has to be more than the number of electrons.E < P
A negative ion that has a negative charge - The number of electrons has to be more than the number of protons.E > P
Thus, the correct answer is - Electron (E) = Proton (Protons).

Answer:
Cell membrane - Controls the passage of materials into and out of a cell
Flagella - Acts as a whipping propeller, moving a cell through its environment
Lysosomes - Digest foreign substances and worn out cell parts
Mitochondria - Produce energy (ATP)
Ribosomes - Makes proteins
Cilia - Structures shaped like small oars that beat in unison to move the cell or the liquid around it
Nucleus - Protects DNA and is considered the “brain” of the cell
Golgi Apparatus - Modifies and packages proteins
Explanation:
The cell membrane separates the inside of the cell from the external environment, and regulates substances that enter and leave the cell.
The nucleus contains the genetic material of the cell, and therefore controls all cellular activities. It is also the site of transcription of mRNAs. mRNAs are translated at ribosomes.
The ribosomes are like factories that synthesize proteins through the process of translation.
When proteins have been produced, they are modified, packaged, and transported to their specific sites by the Golgi apparatus.
Mitochondria are energy-producing organelles - the site of cellular respiration.
Lysosomes are membrane-bound sacsin which waste products are digested
Some cells have cilia, which are hair like-structures that beat in unison to aid in locomotion. Another locomotory organelle is the flagella, which is a whip-like structure that helps some single-celled organelles to move.

Explanation:
Prokaryotic cell: contain DNA, are surrounded by a cell membrane, were the first photosynthetic organisms on earth.
Eukaryotic cells: can be specialized for specific tasks in multicellular organisms, contain DNA, contain Nuclei, are surrounded by a cell membrane.
Prokaryotic cells are the earliest cells to be formed in the pre-oxygen earth. The photosynthetic prokaryotic cells released oxygen into the atmosphere during the process of photosynthesis and as such, other forms of cells were able to evolve. Prokaryotic cells lack a nucleus and membrane-bound organelles. Their DNA lies freely within the cytoplasm but the cell itself is surrounded by a cell membrane that controls the movement of substances in and out of the cell.
The eukaryotic cells evolved much later after the prokaryotic cell. It has both nucleus and membrane-bound organelles. The DNA is located in the nucleus and the cell is also surrounded by the cell membrane. The eukaryotic cells can aggregate together to form tissues, organs, or systems for a specific task in multicellular organisms.
