A is the only statement which can be considered true given the assumed conditions.
Catalyst is a substance that speeds up a chemical reaction, but is not consumed by the reaction; hence a catalyst can be recovered chemically unchanged at the end of the reaction it has been used to speed up, or catalyze.
Answer:
Cell divison is defined as the process in which a parent cell split into two or more daughter cells. There are three stages of cell division that includes interphase, mitosis/meiosis and cytokinesis.
In the interphase the proteins, enzymes and cell organelles are formed and at the end of this phase single strand chromosome becomes a double strand carrying genes.
In the meiosis (in sexual reproduction) or mitosis (asexual reproduction) phase, divison of nucleus takes place. Meiosis gives rise to geneticaly different cells due to crossing over while mitosis leads to identical cells .
Cytokinesis occurs cocurrently after meiosis or mitosis in which cytoplasm of a parental cell divides into two daughter cells each with identical chromatin.
Creation of new animals are also undergo these 3 stages of cell division that is interphase, meiosis (eukaryotes)/mitosis (prokaryotes) and cytokinesis. Majority of animals (eukaryotes) undergo meiosis phase because their mode of reproduction sexual and have genetic variation due to crossing over of chromosomes and produces 4 daughter cells at the end cell division.
Hence, the 3 stages of cell division is similar to craetion of new animals.
1. rise of angiosperms
2. rise of chemoautotrophs and photoautrophs
3. rise of multicellularity
4. rise of bryophytes
5. rise of gymnosperms
6. rise of eukaryotes
7. rise of cyanobacteria
You can draw a free body diagram with two 250N forces acting on the human, one from each side. The net force is 0 because the two applied forces cancel each other out since they are in opposite directions.
