In cell biology, cytokinesis results in two separate:
cells |
|
chromosomes |
|
nuclei |
|
chromatids |
During cell division, the cytokinesis phase occurs when cytoplasm and cell membranes complete their separation resulting in two separate cells.
Convert 5C° to F°.

To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(5) + 32\)
\(F° = {45 \over 5} + 32\)
\(F° = 9 + 32 = 41\)
In a eukaryotic cell, which organelles deal with proteins?
all of these deal with proteins |
|
endoplasmic reticulum |
|
ribosomes |
|
Golgi apparatus |
The nucleus of a eukaryotic cell contains the genetic material of the cell and is surrounded by cytoplasm which contains many organelles. Ribosomes produce proteins, endoplasmic reticulum helps synthesize proteins and fats, and Golgi apparatus prepares proteins for use.
The envelope of gases surrounding the planet is called the:
atmosphere |
|
lithosphere |
|
hydrosphere |
|
geosphere |
The biosphere is the global ecological system integrating all living beings and their relationships. This includes their interactions with the lithosphere (the rigid outer part of the earth, consisting of the crust and upper mantle), hydrosphere (all surface water), and atmosphere (the envelope of gases surrounding the planet).
In the pancreas, lipase converts fat to:
complex carbohydrates |
|
simple sugars |
|
glycerol and fatty acids |
|
amino acids |
The acids produced by the pancreas contain several enzymes that aid in digestion. Lipase converts fat to glycerol and fatty acids. Pancreatic amylase breaks down complex carbohydrates into simple sugars. Trypsin converts polypeptides (the building blocks of protein) into amino acids.
