Answer:
1-Ecological succession is the process of change in the species structure of an ecological community over time.
2-Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.
3-A limiting factor is a variable of a system that causes a noticeable change in output or another measure of a type of system.
Explanation:
Answers:
thorium-234
Explaination:
Isotopes are defined as the variants of a particular chemical element obtained by radioactive decay which makes it differ in neutron number and nucleon number but have the same number of protons in each atom.
Uranium-238 produces thorium-234 by alpha decay. alpha particle is a helium nucleus which carry 2 neutrons andn 2 protons with the mass number 4. In alpha decay, nucleus emits alpha particles which tranforms or decay into an atom with a mass number 4 less and an atomic number 2 less.
The equation for alpga decay is attached below:
Hence, the isotope is thorium-234 .
Bone canaliculi are microscopic canals between the lacunae of ossified bone. The radiating processes of the osteocytes (called filopodia) project into these canals. These cytoplasmic processes are joined together by gap junctions. ... In cartilage, the lacunae and hence, the chondrocytes, are isolated from each other.
At 5.0 they start to die off so that means 5.5 is where they are dead
