Prokaryotes don’t have organelles (which are the cell’s ‘organs’ that carry out the cells functions).
Plant cells and animal cells are eukaryotes because they have organelles.
Plant cells are kind of stiff because of their structure. They have a cell wall, which is really tough. Also, plant cells perform photosynthesis, using an organelle called a chloroplast. Finally, plant cells have a large vacuole that stores the cells waste.
Animal cells, unlike plant cells, lack a cell wall. That means they’re free to wiggle if they wanted to. Animal cells have lysosomes that assist in reproduction.
The factors are muscle Force - Velocity Relationship, motor
units recruitment, Length-tension relationship, angle of pull and Active and
passive insufficiency. When muscle is contracting (concentrically or
eccentrically) the rate of length change is significantly related to the amount
of force potential.
The right answer is law of segregation
Mendel derives from his observations two fundamental principles, to which will be added later a third resulting. In his case, experiments on peas enabled Mendel to formulate the principles involved in heredity.
<u>Mendel discovers that:</u>
* A character can present two different forms (today called alleles or homologous genes).
* An organism inherits two factors for each trait (Mendel's hereditary factors are now called "genes").
* The dominant factor masks the recessive factor. Mendel noted the dominant factor using a capital letter and the other, the recessive, using the same letter but in lower case
.
* The two factors separate during gamete formation (Segregation law that corresponds to the separation of homologous chromosome pairs during meiosis)
.
* The pairs of factors separate independently of each other (independent segregation law that corresponds to the independent assortment of chromosome pairs homologous to metaphase 1 of the first meiotic division).
Answer:
Hey!
The formation of the North-Atlantic deep water current involves the conversion of warm salty sea water from the Equatorial area moving to the cold dense deep waters behind the Greenland-Iceland-Scotland Ridge.
The mixture of the warm and cold waters causes the current to form and then moving clockwise from Greenland towrads Scotland and Norway

Answer:
False
Explanation:
Chief cells usually secrete pepsinogen, but the product does not related is to acidity.therefore, Whenever
HCl secreted by the parietal cells activate pepsinogen, the pepsinogen is converted into pepsin, and pepsin is an enzyme that acts on proteins.
NOTE:
The gastric chief cell is one of the cells in our stomach that brings about the release of pepsinogen and chymosin. Pepsinogen is activated into the body's digestive enzyme pepsin and the pepsin will have contact with acid that is produced by gastric parietal cells.
Pepsinogen is substance that is secreted into gastric juice from both mucous cells and chief cells. After secretion pepsinogen is activated into the active protease pepsin by the stomach acid.the protease pepsin helps the stomach's ability to initiate digestion of proteins.
