Answer:
Reproduction, growth and development, regulation, homeostasis, and energy processing.
Explanation:
Reproduction, growth and development, regulation, homeostasis, and energy processing are the traits or characteristics that are determined by the genotype. These traits are under the control of genes of an organisms and can be changed if the change in the genes occurs while on the other hand, the physical characteristics of an organisms are determined by phenotype means phenotype is responsible for the appearance of an organisms.
Many of the organisms that had existed on the earth left no fossils because most of them can not meet the conditions that must be fulfilled before fossils can form. For fossils formation to occur, the organism soft tissue must decay leaving behind the hard part [majorly bone] in the sediment. Overtime, layers of sediment have to build up and pressed down on the buried remains. As time goes on, water and mineral seeped into the remains and form crystals.
This is very much false because people tend to be very destructive.
1. Answer;
A. energy flows in one direction and nutrients recycle.
Explanation;
-The movements of energy and nutrients through living systems are different because the energy flows in one direction and nutrients recycle.
-Energy is transferred between organisms in one direction in a food chain, but that interconnected food chains make a food web.
-Most ecosystems get their energy from the Sun. Producers can use sunlight to make usable energy by converting it into chemical energy or food. Consumers get some of that energy when they eat producers, they pass some of the energy to other consumers when they are fed on.
2. Answer;
Nitrogen fixation.
Nitrogen fixation depends on bacteria.
Explanation;
Nitrogen fixation is the process by which nitrogen is taken from its stable gas form (N2) in air and then converted into other nitrogen compounds (such as ammonia, nitrate and nitrogen dioxide) useful for other chemical processes.
-The nitrogen fixing bacteria are microorganism capable of converting atmospheric nitrogen into forms usable by plants. They include the free-living bacteria, which includes cyanobacteria, azotobacter etc. and others such as mutualistic bacteria such as Rhizobium.
Once Oxygen reaches the blood via the lungs, it is taken in by a protein known as haemoglobin (Hb) in the red blood cells. Oxygen then binds to a heme group located within a subunit of the protein (Hb). A single heme group can bind 1 oxygen molecule, there are 4 heme groups all together meaning 4 oxygen molecules forming Oxyhaemoglobin. Oxygen is then diffused into local tissue by the Haemoglobin. - this was rushed sorry if it doesnt make alot of sense hope it helps tho
