A hypothesis Is when someone thinks of the answer and a theory is when a group of people think of an answer
Isotopes are variants of a particular chemical element which differ in neutron number (neutral particle)and all isotopes of a given element have the same number of protons (positive particle) in each atom.So isotope B of the sodium will have 11 protons, 11 electrons but it may have a wide range in its number of neutrons.
The answer would be: <u>Molten material that cooled quickly.</u>
Igneous rocks are formed by the cooling of molten material. So we can cross out the last two choices. The rock has no identifiable crystals so it is most likely an Extrusive igneous rock. They form on the surface where they cool quickly.
Those that form underground are called intrusive rocks. They cool slowly allowing enough time for crystal formation.
The correct answer is Phagocytosis type of endocytosis is the cellular process of engulfing liquid particles by the cell membrane.
Phagocytosis is a type of endocytosis in which large particles such as microorganisms and dead cells are ingested through large endocytic vesicles known as phagosomes. Phagocytosis is the process of detecting and absorbing particles larger than 0.5 m in size. The particle is internalized into the phagosome, a distinct organelle. This phagosome then undergoes phagosome maturation, which involves changing the structure of its membrane and the composition of its contents. The first step is to activate the phagocyte.
Step 2: Phagocyte Chemotaxis (for wandering macrophages, neutrophils, and eosinophils)...
Step 3: Phagocyte attachment to the Microbe or Cell.
Step 4: The Phagocyte consumes the microbe or cell.
