Answer:
prokaryotic and eukaryotic
Explanation:
Nucleus Cytoplasm
Contains the genetic material (DNA) Contains a thick gel-like substance
The most obvious structure in the cell Contains all organelles
Contains directions for cell regulation Mostly water
The nucleus is a large and obvious organelle in the cell and it provides instructions for the regulation of the cell's activities and it contains the genetic material (DNA). All organelles are embedded in the cytoplasm which is made up of mostly water.

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.
Answer:
The three stimuli that cause the plants to exhibit tropism are:
1. Touch: This stimulus triggers thigmotropism, which is the turning or bending of the plant and tendrils in response to the touch.
2. Light: This stimulus triggers phototropism. It is how the plant reacts toward the direction of the light source. In this case, the stem may bend in response to the direction of the light.
3. Gravity: This stimulus triggers phototropism gravitropism, which is responsible for the downward growth of roots into the soil.
