<u>Answer</u>: A) They have been geographically isolated from each other for a longer time.
<u>Explanation</u>: An isthmus is defined as a narrow strip of land that separates two bodies of water as well as connecting two larger landmasses at the same time. Thus, an isthmus if an efficient physical barrier that has separated an original shrimp species. This has resulted in the extant deep-water shrimp species through the evolutionary process known as allopatric speciation.
The age of an isthmus is in the range of at least two million years. Thus, the two deep-water shrimp species have been separated from each other for a very long time.
Its electrons relese and it dies. or another way to say it is that it burns.
Answer:
The correct answer is - slightly lower than the body.
Explanation:
Spermatogenesis is the process of the generation of sperm. It is the process that requires a slightly low temperature than normal body temperature to produce sperms in viable conditions.
This is the prime reason for the location of the scrotum which is outside the body which allows to testes maintain lower body temperature lower than the rest of the body. There is a 1-8 degrees C difference in the rest of the body and testes.
The answer is; B
Rocks have naturally occurring and spontaneously radioactive atoms in them, such as carbon-14. These element isotopes decay into other types of atoms over millions of years. Therefore, by measuring the amount of these radiometric substances, and knowing the half-life of the isotopes, it is possible to postulate the age of a rock to within certain ranges of error.
The actively dividing cells, or meristems, control plant growth. Primary (apical) meristems, the dividing tissue at the tips of the roots, grow longer roots, and secondary meristems, the dividing tissue seen in the cross-sections, grow thicker roots.
