Answer:

B.

Explanation:

Fossil fuels definitely harm the environment, and their supply is depleting. So that takes out answers C and D, leaving A and B. The main cause of ozone depletion and the ozone hole is manufactured chemicals being released into the air. While CO2 from fossil fuels does have an effect on worsening the hole, it has a much higher effect on global climate change.

How do you change dna to rna to amino acids
yanalaym [24]
This can be done through the Transcription and Translation process.

Long story short: DNA -> messenger RNA (mRNA) -> amino acids -> polypeptide chain -> protein

Step 1: Transcription
1) DNA loop is open
2) RNA polymerase (enzyme in nucleus) catalyze reaction of “unzipping” DNA
3) free RNA nucleotides in nucleus will be added to that strand of DNA
4) messenger RNA moves across nuclear membrane to cytoplasm (our nucleus)

Step 2: Translation
1) messenger RNA attaches to ribosome
2) mRNA determines which amino acid to place on protein
3) uses codons (triplet) on mRNA. Codon on mRNA and anticodon on tRNA have to match, which places true amino acid in ribosome, then it detached and finds another amino acid in cytoplasm.
4) “AUG” starts translation, and keeps going until reaching “stop codon”.
5) completed polypeptide chain results to protein being synthesized

Your teacher should explain this process more in depth hopefully

What causes reactive hyperemia to increase tissue perfusion? local controls hormonal controls respiratory controls urinary contr
Over [174]
I believe that local controls are what causes reactive hyperemia to increase tissue perfusion. Reactive hyperemia or venous hyperemia is the transient increase in organ blood flow that occurs following a brief period of ischaemia. 
Tissue perfusion is the decrease in oxygen resulting in the failure to nourish the tissues at the capillary level. Local blood flow regulation involves the rapid control of arterial vasomotion based on the metabolic needs of the surrounding tissues and cells.

What did Darwin conclude about the finches on the Galapagos Islands that later supported his theory of evolution? Check all that
Ahat [919]

Answer:

The finches on Galapagos Islands had different beak

The beaks of the finches changed over time

The Galapagos finches had a common ancestor

Explanation: Darwin's Finches are a good example of natural selection and adaptive radiation of evolution. The different finches in Galapagos Island have emerged from a common  black, seed eating, short beak finches. This is called adaptive radiation, where different species arose from a single ancestor.

Due to changes in the natural environment, food resources, some finches have a long beak. This long beaks help them to eat insects. As a result, the competition will be less and nature selects them to survive in the new environment. This is a natural selection of evolution.
