Vertebrates:
1) They've got a backbone/spine.
2) Are probably more complex organisms: fish, amphibians, reptiles, birds, mammals (in that order.)
3) Movement is based on an internal skeleton.
4) Wide range of sizes and shapes.
5) K-selected population
Invertebrates:
1) No backbone.
2) Less complex: sponges, worms, mollusks (e.g. snails) , crustaceans (e.i. crabs.) Insects.
3) Movement is not based on an internal skeleton, or some don't move at all.
4) Must be small in size to fulfill their needs for air and nutrients because systems are simpler.
5) R-selected population
<u>Answer</u>: 0.83 (=0.88-0.05)
Growth rate is the speed/rate at which the number of individuals within a population increases.
As the current growth rate of the fog beetles is 83%, the population will increase with 1660 individuals per reproductive cycle (N=N0*r --> N=2000*0,83 --> N=1660).
Answer:
A. COAGULATION
Explanation:
Hemostasis is stopping bleeding. To prevent or keep blood in the blood vessels due to damage of the vessels.
Three steps are important in hemostasis;
1. Vasoconstriction : which is the contraction of the smooth muscles of the blood vessels reducing the amount of blood flow to the area of damage and thereby blood loss.
2. Platelet Plug Formation: this is the function of platelet in the blood. It attaches to the damaged endothelium and form a plug.
3. Coagulation/ Clotting : this is the release of clotting factors to the surface of the damaged vessel.
Fibrin is a major component of the clotting factor.
So therefore, coagulation is a process in hemostasis. Formation of platelet plug is a stage also and not the formation of platelet in the blood.
