Answer:
Because we cannot see some animals properly like jellyfish as their tissue is too soft, and feathers or for can often not make an imprint on fossils.
Explanation:
The ecosystem that would most likely have a very high net primary productivity is a tropical rain forest. This type of an ecosystem is characterized by constant temperature, high annual rainfall, nutrient-poor soil, and high levels of diversity. The level of humidity and density of the vegetation give the ecosystem a unique water and nutrient cycle.
Answer:
Fossil fuels
explanation: Coal is one type of fossil fuel. This is a nonrenewable energy source whose extraction often damages the environment. Fossil fuels are made from decomposing plants and animals. These fuels are found in the Earth's crust and contain carbon and hydrogen, which can be burned for energy

Answer;
An excess one of the components of hemoglobin decreases tbc survival
Explanation;
-Each hemoglobin molecule is made up of four heme groups surrounding a globin group, forming a tetrahedral structure. Heme, which accounts for only 4 percent of the weight of the molecule, is composed of a ringlike organic compound known as a porphyrin to which an iron atom is attached.
-Heme is synthesized in a complex series of steps involving enzymes in the mitochondrion and in the cytosol of the cell. Two distinct globin chains (each with its individual heme molecule) combine to form hemoglobin. One of the chains is designated alpha. The second chain is called non-alpha.
