Answer:
F) Thermohaline circulation pattern move surface water from equatorial regions to the poles
I think that since it lives on the ocean floor, at the deepest of the ocean. So anyway, the fin on the Eurypterids is still necessary but not that much, since they live on the ocean floor. Their movements mostly on the ocean floor. So fin would not help them "stick" to the floor. Also there are still gravity acts on the Eurypterids and the feet would help them move faster. Hope this helps.
Answer:
Explanation:
The bacteriostatic antibiotics can be defined as those antibiotics, which prevents the growth of bacteria. These keeps the growth of bacteria in the stationary phase so that bacteria cannot cause harm to the host.
The bactericidal antibiotics can be defined as those antibiotics, which kills the bacteria.
The example of bacteriostatic antibiotic is Tetracycline that it inhibit the bacteria ribosome production of proteins. This way bacterial growth and reproduction will get restricted.
The example of bacteriocidal antibiotic is polymyxin B. It causes injuries to the plasma membrane of the bacteria which can be lethal for bacteria.
In cardiac muscle
a. an action potential spreads throughout the Z discs.
b. intercalated discs connect the muscle fibers together.
c. calcium enters the cell from storage chambers called intercalated discs.
d. potassium is released from the sarcoplasmic reticulum
Answer:
b. intercalated discs connect the muscle fibers together.
Explanation:
Intercalated discs are components of the muscles found in the heart(cardiac muscles).
Intercalated discs join the cardiomyoctes (muscle cells or fibers) together so that they can function as one and transmit signals amongst themselves during the contraction of the heart.
Intercalated discs are made of up desmosomes and gap junctions.
Intercalated discs are found on the lining of the sacromere and can only be seen by using a microscope to observe the longitudinal section of the heart tissue.
