Answer:Tissue
Explanation:Heart muscle cells beat in unison to push blood in timing with the rhythm of the heart, at the direction of nearby nerve cells. These muscle cells could best be called. Tissue. As cell division proceeds, the cells increase in number, but also become specialized in structure and function.
Yes you are correct. Nice job!

Answer:
Crush the limestone... it would give more area for the acid to react
Explanation:
when the limestone is crushed, irt will expose more surface area to the acid making the reaction go quicker.
OPTIONS:
1. reproductive isolation
2. sympatric speciation
3. habitat isolation
4. prezygotic barriers
Answer:
All of the above
Explanation:
First, let us consider the definition of the above listed terms in the question and see each come to play in the hypothetical situation.
Reproductive isolation occurs when two similar species become prevented from mating together as a result of environmental barriers. This can be seen in the flea population, as they become separated by ecological barrier, since some now live on pronghorn antelopes, while others live on cattle.
Sympatric speciation is a speciation that occurs when new species evolved from an ancestor that they share the same geographical region together, but dwell in overlapping different ecological area.For example, fleas that have preference for cattle blood evolved from pronghorn antelopes fleas, as their ancestor. The two species both dwell in overlapping ranges but still in the same rangeland.
Habitat isolation is a barrier that prevents two species from interbreeding as a result of differences in where they live. For example, fleas on cattle cannot interbreed with fleas on pronghorn antelopes.
Prezygotic barriers are reproductive mechanisms that prevent fertilization. Habitat isolation is an example of prezygotic reproductive mechanism that prevents fertilization to take place between fleas on cattle and fleas on pronghorn antelopes.
