The scientific method steps are
1. Observe
2. Question
3. Hypothesis
4. Production based on the hypothesis
5. Test
6. Use results to conclude if your hypo was right or not.
7. Make a new hypo
The method is a scientific way of finding the answer to your questions. Or in other words. Gathering knowledge that is based on characterized and developed scientific evidence.
Answer:
they are machines or devices build to find la DNA trace and copy it multiple times.
Explanation:
DNA machines are machines built to find a DNA line and copy it multiple times, so scientists can read, observe, and find information about the DNA strand. For example, DNA machines can determine if someone is related, if someone has cancer, and it can distinguish a person’s ancestry. Mainly this is how forensic science uses to determine when there's a suspect in a crime.
Answer:
The answer is insulin.
Explanation:
Pancreatic juice is an enzyme containing secretion produced by the pancreas into the small intestine. Enzymes in the pancreas help in digesting proteins, carbohydrates and fats. The constituent enzymes are as follows:
- Trypsinogen and Chymotrypsinogen: Precursors of the proteases, trypsin and chymotrypsin that digest proteins. They are released as precursors to protect the intestinal lining. Enterokinase, an enzyme secreted by small intestine's epithelial cells, activates these precursor.
- Lipase: Enzyme that digests lipids by hydrolysing triglycerides into 2-monoglyceride and two free fatty acids.
- Amylase that helps in digesting any left over carbohydrates and complex starch.
Insulin:
Insulin can never be part of pancreatic juice because it is a hormone, not an enzyme. Hormones are chemical messengers secreted only in blood. Insulin is a hormone secreted by the pancreas to lower blood glucose levels by binding to insulin receptors on cells and stimulating the intake of glucose through glucose transport channels (GLUTs) in the cell membrane.

Answer:
1.
mRNA - Messenger RNA: Encodes amino acid sequence of a polypeptide.
tRNA - Transfer RNA: Brings amino acids to ribosomes during translation.
rRNA - Ribosomal RNA: With ribosomal proteins, makes up the ribosomes, the organelles that translate the mRNA.
2.
Transcription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis. Transcription takes place in two broad steps. First, pre-messenger RNA is formed, with the involvement of RNA polymerase enzymes.
3.
During translation, which is the second major step in gene expression, the mRNA is "read" according to the genetic code, which relates the DNA sequence to the amino acid sequence in proteins. Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid (hence, it is a triplet code). The mRNA sequence is thus used as a template to assemble—in order—the chain of amino acids that form a protein.
