Answer:
Organs
Explanation:
When a group of tissues work together to perform a particular role in the human body, they make up an organ.
Answer:
The correct answer will be-pachytene, prophase I,
Explanation:
Tetrad is the structure formed during the meiotic type of cell division which produces four daughter cells.
The tetrad structure is seen under the microscope during the pachytene substage of prophase I.
The tetrad structure is formed when four sister chromatids are aligned together in a cell before the crossing over event or recombination has to take place. The tetrad formation allows the crossing over to take place in pachytene.
Thus, pachytene, prophase I is the correct answer.
Answer:
I think it's
A <u>mass </u>extinction occurs when many species go extinct in a relatively short period of time.
Explanation:
Mass extinction is usually defined as a loss of about three-quarters of all species in existence across the entire Earth over a “short” geological period of time. Hence, I think the answer is correct.
When temperature is increased, molecules come together more frequently and with greater energy. Because chemical reactions need a certain amount of energy to occur, increasing the energy of the molecules involved in the reaction can speed up the rate at which the reaction occurs.
