Air pollution and water pollution are more often regional problems than global problems. Water pollution involves the contamination of water bodies such as rivers, lakes, oceans, and groundwater; usually caused by human activities. Air pollution is the release of pollutants into the air; harmful or excessive quantities of substances such as gases, biological molecules, and particulates.

Answer:
•The dodder plant is parasitic.
•The dodder plant stays alive because of the potato plant.
Explanation:
A parasite cannot survive or reproduce without its host because it depends on it. The dodder plant is parasitic to the potato plant because it derives its nutrition from the potato plant which is the host. The potato plant is denied its nutrient and therefore grows weakly below its maximum potential. The dodder plant gains while the potato plant is negatively affected- that’s parasitism relationship.
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.
