The Law of Conservation of mass is important because then when performing a chemical reaction scientists can determine about the amount of substance that will be produced.
Organism in which the embryonic blastopore becomes its anus Deuterostome
<u>Explanation:</u>
The term Deuterostome refers to second mouth. The first opening which is called blastpore becomes its anus in deuterostomes. In protostomes, this first opening will be the mouth. The other name given to these Deuterostomes enterocoelomates. It is the enterocoely from which the coelom of Deuterostom starts emerging and growing.
Chordata, Echinodermata, Hemichordata are the classes of deuterostomes:. The zygote is the one that gets developed first in protostomes and deuterostomes.Radial cleavage occurs in deuterostom in which the division of cells lies either in parallel direction or in perpendicular direction with respect to the polar axis.
Answer:
All living things are made up of cells. Cells are building blocks of life. Cells are the simplest level of organization. The structure of multicellular organisms are made up of many parts that are required for survival of organisms. The level of organization in multicellular organisms includes: cells, tissues, organs and organ system. The organization is necessary for the body of the organisms to function properly as a characteristic feature of living being.
Magnifying glass is a convex lens that is fitted in a microscope can be used to magnify the image of object under observation. A magnifying glass in a microscope can be used to magnify minute cells and small living creatures. All cells aggregate to form tissues. It can be used to see the arrangement of cells in a tissue specimen and small organelles like chloroplast, mitochondria, nucleus and others.
Therefore, observations under the magnifying glass support the idea of organization is one of the characteristics of life.
Explanation:
