Respuesta:
Las células están formadas por un núcleo y un citoplasma, encerradas por una pared delgada llamada membrana, que las separa de su entorno. Las células vegetales también tienen núcleo, citoplasma y membrana celular. La principal diferencia entre una célula vegetal y una animal es que las células vegetales tienen una vacuola, un cloroplasto y una pared celular.

Question:
How to know that something is made up of a cell
Answer:
Cells are made up of a nucleus, and a cytoplasm, enclosed by a thin wall called a membrane, which separates it from its surroundings. Plant cells have a nucleus, cytoplasm, and a cell membrane too. The main difference between a plant and an animal cell is that plant cells have a vacuole, chloroplast, and a cell wall.

What molecules diffuse through the cell membrane without the use of energy and are required as reactants in photosynthesis?
A.glucose and oxygen
B.water and oxygen
C.glucose and carbon dioxide
D.water and carbon dioxide
Answer:
c
Explanation:
If the substances can move across the cell membrane without the cell expending energy, the movement of molecules is called passive transport. Consider substances that can easily diffuse through the lipid bilayer of the cell membrane, such as the gases oxygen (O 2) and carbon dioxide (CO 2)

what process can lead to an individual having too many or two few chromosomes?
The process which can lead to an individual having too many or two few
chromosome is as a result of mutation which occurs during meiosis.
Meiosis is the type of cell division which occurs in reproduction and the
production of sex cells such as sperm and egg. This process results in the
production of four unique daughter cells.
The homologous chromosomes not being properly distributed in the
process could lead to such types of error.

why does exposure to high temperatures cause an enzyme to lose its biological properties?
Answer:
Shape of active site changes that's why
Enzymes are affected by temperature. So, as temperature increases, enzymes activities also increases, till optimum temperature is reached. If it goes above the optimum temp, the enzymes becomes denatured or can't function anymore due to change in its active site.

Summary about DNA , Genes , Traits , Chromosomes. (Explain & let me know about all 4 words. Summarize all these words.) Write about how all 4 things work together.
Answer:
Genes are segments of DNA that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus. And a trait is a gene-determined characteristic.

Answer:
16. mitochondria
17. lysosomes
18. smooth Endoplasmic Reticulum
19. golgi body
20. golgi complex
Explanation:
16. Mitochondria are double membrane-bound cell organelles responsible for the supply and storage of energy for the cell
17. While cells mainly use lysosomes to dispose of trash. Sometimes they simply hang onto their trash, performing the cellular equivalent of sweeping it under the rug
18. Are the storage organelle, associated with the production of lipids, steroids, and also responsible for detoxifying the cell.
19. The Golgi body is the sorting organelle of the cell. Proteins are transported from the rough endoplasmic reticulum (RER) to the Golgi.
20. is responsible for sorting and correctly shipping the proteins produce the ER. Just like our postal packages, which should have a correct shipping address, the proteins produced in the ER should be correctly sent to their respective address. It is a very important step in protein synthesis.

what organelle acts like a whip to move the entire cell
Answer: Flagella
Flagella are longer, whiplike projections that propel cells. Both cilia and flagella are composed of microtubules. They move cells through their watery environments. Cilia also move substances along the surface of the cell.
A fingerprint is visualized on a soda can using superglue. What type of fingerprint is this?
A) bifurcation
B) latent
C) patent
D) plastic
Fingerprints in modern times are now used in detecting criminals from crime scenes. Fingerprints derived from these crime scenes can be obtained and visualized.
The type of fingerprint this is is a latent fingerprint.
Latent fingerprints can also be referred to as invisible type of fingerprints.To enable their use, they must be visualized through the use of various techniques which include dusting/iodine/super glue. Latent fingerprints are the most common type of fingerprints usually found at a crime scene. They are also much harder to detect and lift than any other type of fingerprints.Learn more about fingerprints: https://brainly.com/question/2114460

between atoms, What is the name for
this stored energy?
A kinetic energy
B chemical energy
C electrical energy
D electromagnetic energy
A form of energy that is stored in the bonds between atoms of a chemical element is referred to as: B. chemical energy.
A chemical energy can be defined as a form of energy that is stored within the forces of attraction (bonds) that are existing between ions, crystals, atoms or molecules.
In Chemistry, bond energy refers to the amount of chemical energy that is required to break one (1) mole of a particular chemical bond. Also, bond energy is measured in kJ/mol.
In conclusion, a form of energy that is stored in the bonds between atoms of a chemical element typically is referred to as chemical energy.

Why can cells in the bone marrow produce both red and white cells
Answer:
1.Bone marrow produces red blood cells, platelets, and white blood cells. Lymphocytes are produced in the marrow, and play an important part in the body's immune system.
Explanation:
2.After entering the bloodstream, the hematopoietic stem cells travel to the bone marrow. There, they begin to produce new white blood cells, red blood cells, and platelets in a process known as engraftment.
3.Red blood cells are an important element of blood. Their job is to transport oxygen to the body's tissues in exchange for carbon dioxide, which they carry to the lungs to be expelled. Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow are called hemocytoblasts.

If ATP production is blocked, decreased transport of material across a membrane occurs. Which type of transport would be affected
Answer: Active transport
Explanation:
This transports requires ATP because the material would be going against the gradient (Low to high concentration). Since this is not the "normal" tranportation (High to Low concentration) it therefore needs ATP. Without ATP it cannot do it's transportation.
