Answer:
The cells that make up the digestive, muscular, skeletal, reproductive, and excretory systems all need oxygen from the respiratory system to function, and the cells of the respiratory system as well as all the other system bneed nutrients and must get rid of metabolic wastes.
Explanation:
Answer:
B) Messenger RNA
Explanation:
Messenger RNA [mRNA] molecules carry the coding sequences for protein synthesis and are called transcripts.Ribosomal RNA [rRNA] molecules form the core of a cell's ribosomes [the structures in which protein synthesis takes place] and transfer RNA [mRNA] molecules carry amino acids to the ribosomes during protein

Answer:
B, it will rotate and face the sun.
Explanation:
The Earth rotates a lot, especially in 5 hours. It will not be stationary. It is most likely that at 8 AM, the Earth will be facing the sun, not away from the sun.
B. it had to have been in a warm area and then moved there by plate tectonics over time due to the warm-climate plant fossils found there
Explanation:
One evidence that suggests that ancient Antarctica was situated in a different location from today is seen in the warm-climate fossils plants found there.
- Antarctica today occupies the southern polar region of the earth.
- It the coldest region on earth with very extreme of cold.
- From the theory of continental drift proposed as subset of plate tectonics, the continent Antarctica was once a landmass in a tropical region with lush green plants.
- Fossils of palm fronds and seeds of tropical plant species have been unearthed in some sedimentary layers in the continent.
- The scientific explanation to this is that the continent was once up above it's current position.
