Answer:
Explanation:
At the ending of pro phase or late prophase, the mitotic spindle begins to capture and organize the chromosomes.
* The chromosomes have finished condensing and are now very compact.
* The nuclear envelope is broken down and the chromosomes are released.
* The mitotic spindle grows more, and some of the microtubules start to “capture” chromosomes.
Answer:
Secondary structure proteins folding
Explanation:
Alpha helix and pleated sheets are basically two types if secondary structure of Proteins.
You have to put a lid on petri dishes in order to ensure that no outside contaminants get inside the dish.
Answer:
Organnelle
Ribosomes
Nucleus
Archaeabacteria
Phospholipid bilayer
Lipases
Explanation:
1. Organnelles are specialized structures in a cell designed to perform a particular function that will make the cell normal e.g. ribosome, Chloroplast, mitochondrion are examples of organnelles.
2. The Rough Endoplasmic Reticulum (RER) is one of the two endomembranous systems in the cell. It is characterized by its rough appearance which occurs as a result of ribosomes attached to its surface. This attachment of ribosomes makes its function related to protein synthesis.
3. Nucleus is a membrane bound organnelle found only in EUKARYOTIC cells. It houses the genetic material (DNA) of a cell and acts as the brain by directing all of the cellular activity of that cell.
4. Archaeabacteria is one of the six kingdoms in the hierarchical classification of living organisms. They contain unicellular and prokaryotic organisms that are uniquely characterized by their ability to survive extreme conditions e.g high temperature.
5. The plasma membrane is an outer covering that bounds the cells of both Prokaryotic and eukaryotic organisms. According to the fluid mosaic model that describes the structure of the cell membrane, it contains a phospholipid layer that confines its selective permeability upon it i.e. ability to control what goes in and out of the cell. This is due to the amphipathic nature of the phospholipid i.e. contains an hydrophobic and hydrophilic region.
6. Lipases are enzymes that are involved specifically in the breakdown of lipids and fat molecules into fatty acids and glycerol.
