A. they both have prophase and metaphase. Mitosis and meiosis have the same steps, just a few of the steps are different, and in meiosis the steps are done twice.
Answer:
Only about 5% of human DNA encodes protein.
Explanation:
Arrayed along the DNA strand are the genes, specific regions whose sequences carry the genetic code for making specific proteins. The genes of bacteria are tightly packed together; virtually all the DNA encodes proteins.
Number 3 is microorganisms.
Answer:
B. The bird will stop flying because it will quickly use up its remaining
energy.
Explanation:
This is because the mitochondria is known as the power house of cells. Oxidative phosphorylation takes place in this organelle and it involves the conversion of ADP to ATP through the hydrogen ions(protons).
When the hydrogen ion channel is blocked, energy production in cells stop.
This is why the bird will stop flying as it would have used up its remaining energy and won’t have a new one to use to continue flying.
I really hope this helps!
The main dangers worldwide are population growth and resource consumption, climate change and global warming, habitat conversion and urbanisation, invasive alien species, over-exploitation of natural resources and environmental degradation.
