Answer:
Lipid Droplets are cell structures that store fat in the form of neutral lipids, these droplets are hydrophobic (do not interact with water) which is why they are surrounded by a phospholipid monolayer, with the hydrophobic phospholipid tails oriented toward the neutral lipid core
This is different from most other cellular organelles, which have aqueous lumens and are therefore, surrounded by phospholipid bilayers.
Epithelial cells are mainly used for protection; in the urinary tract, these tissue cells are used to protect the bladder from toxic urine. The tissue can also expand to hold larger quantities of urine.
Answer:The cell cycle a. includes mitosis as an event.
Explanation:
The cell cycle consists of two stages:
interface and phase M (mitosis). In the first, the cell grows and doubles its DNA; It consists of phases G1, G2 and S. In phase M, the cell divides its already duplicated DNA and the cytoplasm divides into 2 (cytokinesis), forming 2 daughter cells. There is a G ° phase, where the cell is in a "vegetative" state, called "senescence." The cell cycle is regulated cyclin / CDK complexes, tumor suppressor genes (example: p53).
The enzyme maltase breaks down disaccharide maltose into simple sugar glucose, which is usable by the body. This glucose can now also be stored in the liver for future use.
This maltase does nor break down sugar sucrose because it is the sucrase enzyme that breaks down sucrose into glucose and fructose.
Answer:
<em>The number of chromosomes is maintained through the process of mitosis during asexual reproduction. </em>
Mitosis can be described as a process in which a cell divides and produces two daughter cells which are exactly similar to the parent cell. The chromosome number of the daughter cells will be the same as the parent cells. No crossing over or recombination occurs during this type of cell division. Hence, mitosis is an effective way to maintain the chromosome number of organisms which reproduce asexually.
