Why are cells relatively small?
Darya [45]

Cells are so small so the surface area and volume of them can be proportional to each other. This helps with the efficiency of the cell's absorption and waste expulsion processes. Also by the cell's smallness, communication from the nucleus to other organelles is fast and the cell can be regulated while the conditions for diffusion are still ideal.Its because they need to be able to diffuse through materials easily. Also, materials inside and outside of the cell need to easily pass through the cell membrane, which makes it harder and slower for the materials to pass through the cell membrane.

Answer:

Viruses are exceptions to the cell theory.

Outside a living medium, virus is considered non living or a crystalline substance.

Describe the way the heart is pumping and creating cardiac output,What are factors that can change cardiac output? Explain the s
Sergeeva-Olga [200]

Blood volume reflexes, hormones, body temperature, emotions, gender and age are the factors that affect cardiac output.

<h3>What are factors that can change cardiac output?</h3>

Factors that affect cardiac output are changing heart rate and stroke volume. Other factors include blood volume reflexes, hormones, body temperature, emotions, gender and age.

Heart sounds are created from blood flowing through the heart chambers when the cardiac valves open and close during the cardiac cycle.

Our heart sends the blood to the lungs, where it receives oxygen and dispose carbondioxide. Then, your heart pumps the oxygenated blood to the tissues and organs throughout your body.

So we can conclude that blood volume reflexes, hormones, body temperature, emotions, gender and age are the factors that affect cardiac output.

As you read your textbook, identify the steps of translation and protein synthesis. Use first, then, next, after, and finally to
Marysya12 [62]

Explanation:

First during protein synthesis, transcription occurs in the nucleus, followed by translation within ribosomes. Then, newly synthesized proteins enter endoplasmic reticulum where they undergo folding and modification. Next, within the golgi body, the proteins are tagged; after,they are finally parceled into lysosomes. Finally, they can be exported out of the cell to fulfill various functions.

Further Explanation:

The endoplasmic reticulum is a membrane system within the cytoplasm that extends from the outer nuclear membrane. Apart from increasing the surface area within the cell, this continuous system also carries out protein folding, synthesis and transport. In the endoplasmic reticulum or ER, some sections called the smooth ER, do not contain ribosomes, and may contain lipids, enzymes, and other proteins. Other sections bound to ribosomes, are called the rough Er. As a protein destined for the endomembrane system is being synthesized by a ribosome, the first amino acids in the growing polypeptide chain act as a signal sequence. That signal sequence ensures that the ribosome binds to the outer membrane of the ER and that the protein enters the ER lumen. The proteins undergo major modifications and are packed into vesicles.

Golgi bodies are flat, disk-like membranous regions. Proteins traverse the organelle by first having their vesicles bind to the cis face or receiving end. Like a post office, the golgi complex, or golgi body recognizes specific signal sequences, targets and further modifies and packages these compounds into lysosomes for delivery to their final destination.  Proteins here undergo peptide processing and glycosylation .
