Doy corono
Es la criatura viviente más simple que se conoce, lo que significa que es capaz de realizar las tres funciones vitales, que son la nutrición, la interacción y la reproducción. Consta de dos partes que son la membrana plasmática y el citoplasma.
Proporcionan estructura al cuerpo, ingieren nutrientes de los alimentos, convierten esos nutrientes en energía y realizan funciones especializadas. Las células también contienen el material hereditario del cuerpo y pueden hacer copias de sí mismas. Las celdas tienen muchas partes, cada una con una función diferente.
What are the main characteristics of epithelial tissues?
they compose glands
they contain blood vessels
they cover the body surface
they form the inner lining of body cavities
they line hollow organs
Answer:
Despite there being many different types of epithelial tissue all epithelial tissue have just five characteristics, these are cellularity, polarity, attachment, vascularity, and regeneration. Cellularity as the name suggests means that the epithelium is made up almost entirely of cells.
The main characteristics of epithelial tissues includes: they compose glands, cover the body surface, form the inner lining of body cavities and line hollow organs.
What is tissue?It is a group of cells having same structure and function.It includes: connective tissue, epithelial tissue, nervous tissue and muscle tissue.What is epithelial tissue?It covers the body surfaces.These are avascular, meaning they do not contain blood vessels.Glands are made up of epithelial tissues.They lines the body's inner cavity and hollow organs.It helps in movement of molecules across the its surfaces.It functions in absorption, secretion and protection.Hence, the correct options are: They compose glands, they cover the body surface, they form the inner lining of body cavities and they line hollow organs.

i think its its either C or D but i don't know correct me if I'm wrong.
A swimmer dives underwater and needs to swim a long distance while holding her breath. This prevents her body from getting oxygen.
What is most likely to occur in her cells so that glycolysis can continue to produce ATP?
a) cellular respiration
b) alcohol synthesis
c) lactic acid fermentation
d) alcohol fermentation
Answer:
C is the correct option.
Explanation:
Cells in the body continue to produce ATP in absence of oxygen.
Lactic acid fermentation is most likely to occur in the swimmer's cells so that the process of glycolysis can continue to produce ATP. Thus, the correct option is C.
What is Lactic acid fermentation?
Lactic acid fermentation is a metabolic process in which glucose or other six-carbon sugars are converted into cellular energy (ATP) and the metabolite lactic acid. It is an anaerobic fermentation reaction which occurs in some bacteria and animal cells, such as muscle cells and in absence of oxygen molecule.
Lactic acid fermentation happens in the skeletal muscles. In this process, pyruvate is converted to lactic acid by the lactate dehydrogenase enzyme when oxygen is inadequate. Fatigue is brought on by the formation of lactic acid which buildup in the muscles.
Therefore, the correct option is C.

in which reactions of cellular respiration does substrate-level phosphorylation occur?
Answer:
During the Kreb’s cycle, also known as the citric acid cycle.
Explanation:
Pick one sentence or paragraph from the article, and explain how it supports the idea that science is an evolving discipline that depends on repeated testing.
Answer:
From Edmentum:
“Paleontologists used to think that dinosaurs were similar across the continents—at least during the Jurassic period, says Novas. C. diegosuarezi’s mix of features now brings a wrinkle of doubt to that idea.” The paragraph explains that this new dinosaur gives some evidence that the dinosaurs in South America were structurally different from dinosaurs in other areas of the world. According to the paragraph, scientists will need to find and examine more dinosaur fossils from this region before they can support this claim. The claim supports the statement that science requires repeated testing.
Reworded:
“Paleontologists used to think that dinosaurs were similar across the continents—at least during the Jurassic period, says Novas. C. diegosuarezi’s mix of features now brings a wrinkle of doubt to that idea.” Paleontologists used to think all dinosaurs were similar all around the world, but the structure of a specific species of dinosaur made them second guess themselves. It seemed that the dinosaurs in South America were evolving different structures and functions than dinosaurs from other continents. The claim supports that the statement needs more testing.
Explanation:
Answer:According to Novas, "Paleontologists once believed that dinosaurs were identical on all continents, at least during the Jurassic era. The combination of traits on C. diegosuarezi currently casts some doubt on that theory. The structure of a particular species of dinosaur caused paleontologists to reevaluate their previous belief that all dinosaurs were globally identical. It appeared that the architecture and functions of South American dinosaurs were evolving differently from those of dinosaurs from other continents. The claim argues in favor of additional testing for the assertion.

How is the cell membrane involved in riding the body of bacteria,
allowing water to enter the cell, and export material out of the cell?
Answer:
The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.

what is the ultimate source of electrons for photosynthesis in plants?
Answer: Water
Explanation:
What is the ultimate source of electrons for photosynthesis?
In photosynthesis, water is the source of electrons and their final destination is NADP+ to make NADPH
Photosynthesis is a plant process to make food and energy. It includes various steps to release energy. The water molecule is the ultimate electron donor in the process.
What is photosynthesis?Photosynthesis is said to be the process that converts solar energy into the chemicals that are used as the energy source in cellular respiration activities. Here, sunlight, carbon dioxide, and water act as reactants.
The carbon dioxide and water undergo splitting by the membrane pigments and then the electron produced from water is carried with enzymes to make NADP⁺. This is further used to make NADPH. As result oxygen along with the sugar molecules are produced and are rich in ATP.
Therefore, water is the foremost source of electrons for photosynthesis in plants.

what is the main function of the reticular activating system?
The reticular activating system's main function is regulating transition between arousal and sleep−wakeness.
what is reticular activating system?The reticular activating system (RAS) is a bundle of nerves located in the brain and it is responsible for regulating wakefulness and sleep-wake transitions.
It is also involve in filtration of noise with processing of messages or make it slower during sleep, it alters the brain's electrical activity, electrical voltage of brain waves and the speed.
The primary function of RAS is higher at brain centres when important messages are received and filter the important messages, for example The eye sends messages to the brain through the optic nerve.
If the RAS system is damaged, it can cause sleep problems, lethargy, or coma, also play a role in narcolepsy and degenerative brain disorders like Parkinson's disease and supranuclear palsy

Suggest why the blood flows through many channels in the dialysis unit, rather than through a single large channel
Hello there I hope you are having a great day :)
Blood travels through many different channels to optimize absorption. The water potential in the solution in the dialysis machine will need to be less than in the blood. If all the blood flows through a single large channel the blood water potential may be more negative than outside, therefore slowing absorption.
