What increases blood pressure?
a) Decreased heart rate.
b) Decreased blood vessel resistance
c) Increased blood volume

What ends a hormonal response to increase blood pressure?
a) Low blood pressure
b) High blood pressure
c) A return to homeostasis.
d) Low blood pressure and a return to homeostasis
When an ecosystem has a scarce nutrient, that is when there is a nutrient limitation.
So the answer is C. <span>Nitrogen is typically the limiting nutrient in freshwater environments.
This is because Nitrogen is the "scarce" nutrient </span>
In human audition, the vibration of the ossicles is triggered by the vibration of the tympanic membrane (the eardrum) and transmitted directly to the fluid and membranes of the inner ear.
The inner ear is shaped like a snail with a thousands of tiny hair cells in it and it is called the cochlea. Hair cells change the vibrations into electrical signals that are sent to the brain through the auditory nerve.
Number 1: The Circulatory System is a vast network that contains organs and vessels.
number 2: Arteries have a thick wall which helps a powerful pressure from the heart.
number 3: Without the Circulatory System the body wouldn't be unable to maintain a internal environment.
number 4: The Circulatory and Respiratory system both have gas to help a or animal live in there internal environment.
number 5: Blood vessels brings oxygen to the tissues and absorbs carbon dioxide and other waste products to clear the lungs. And with out oxygen the tissues won't absorb carbon dioxide to clear out the lungs.
number 6: D
Answer:
To find the extinct species and their divergence of characters can be studied using molecular genetic techniques.
Explanation:
- Paleontology is the study of ancient species and their remaining that were found millions of years ago. These species extinction can be found and manipulated to find out the origin or divergence of species from their origin
- The samples of these species may contains their remains that help the biologist to isolate and analyze their protein or DNA. when the DNA is isolated their sequences can be generated using molecular biology techniques.
- When the sequences are identified by advanced molecular biology techniques, the existence and similarities of different species due to their convergence or divergence can be identified.
- By identifying the convergence or divergence the characteristics, evolutionary change in behavior, variation in appearance can be studied.
- By using these techniques, biologist have found that <em>homo sapiens</em> are 99% have their similarities with chimpanzee
- Thus, using genetics in paleontology helps us to understand adaptation a species is changing according to the evolutionary changes.
