Answer:
No, cardiac muscle tissue does not exhibit recruitment.
Explanation:
The cardiac muscle tissue does not recruit cells to contract. The reason is that the cardiac muscle contracts all its cells at once and with the same force. It does not have to recruit other cells since it does not have to lift objects of different weights. The heart's contraction aims to pump blood and to do it rhythmically. The heart has a natural peacemaker, the sinoatrial node. The Sinoatrial node transmits an electrical impulse to all the heart to contract it all at the same time and continuously. For these reasons, the cardiac muscle does not need recruitment.
Answer: They receive their “orders” for protein synthesis from the nucleus where the DNA is transcribed into messenger RNA (mRNA).
Explanation: This mRNA travels to the ribosomes, which translate the code provided by the sequence of the nitrogenous bases in the mRNA into a specific order of amino acids in a protein.
5. they both photosynthesize.
6. they had to be able to get water from their new environment and retain this water. They also had to adapt to reproduction on land (use of pollinators - this is co-evolution)
7. Because those animals are their pollinators.
