Answer:
Animals breath out carbon dioxide, plants turn the carbon dioxide into carbon and release fresh oxygen as a result. The carbon goes through the rest of the carbon cycle.

Answer:
b. Jejunum
Explanation:
The small intestine is divided into three regions: duodenum, jejunum, and ileum. The jejunum is the middle region of the small intestine and is rich in folds and villi to facilitate the absorption of most of the digested carbohydrates and proteins. The small finger-like projection, the villi, increase the surface area for the absorption of digested nutrients.
Circular folds are the folds of mucosa and submucosa of intestinal lining while villi are the projections of the mucosa into the cavity of the small intestine. Circular folds, villi, and microvilli facilitate the absorption of most of the nutrients in the jejunum.
Answer:
prokaryotes
Explanation:
prokaryotes where the earliest life forms ,simple creatures that fed on carbon compounds that were accumulating an Earth's early.slowly other organisms evolve that use the sun's energy along with compounds such as sulfides to generate their own energy.

I needs points plz dont report my answer
Answer:
mRNA: A-U-G-C-A-U-U-A
Explanation:
Given DNA template: T-A-C-G-C-T-A-A-T
Newly transcribed mRNA: A-U-G-C-A-U-U-A
Transcription is a process that uses DNA template strand to make RNA strands. The process occurs in nucleus. The nucleotide sequence of DNA template is always complimentary to its respective RNA sequence.
Here, thymine of DNA template strand pairs with adenine of newly formed RNA. Adenine of DNA template would pair with uracil of RNA. Guanine of DNA template pairs with cytosine.
