2. If i were a forensic scientistand was called to a crime scene to see if drugs were present in the crime scene iwould use different kind of test to help me determine this, like for examplespectrophotometry tests, Microcrystalline test, and Color test. Because all of these<span>tests would help me to determine if drugs were to be present in the crime scene</span>3.It's important forscientist to have as much information as possible about the place that the drugsubstance is found because many factors can contribute when identifying a type ofdrug and because there might of have been some other substances with the drugand this could affect identifying the drug substance
Answer:
Spindle fibers
Explanation:
During anaphase the two sister chromatids of each chromosome are pulled apart by spindle and dragged by their kinetochores toward opposite poles of the cell.
Answer:
A) many noncoding stretches of nucleotides are present in mRNA.
Explanation:
A transcription unit in eukaryotes includes the region that code for mRNA extending from the 5' cap site to the 3' poly-A site. It also includes the controlling regions. The mRNA formed by transcription also has some non-coding intervening sequences. These are called introns. Introns are removed from the primary transcripts by the process of splicing that occurs after transcription.
Therefore, a transcription unit that is 8,000 nucleotides long may use only 1,200 nucleotides to code for a protein having 400 amino acids since the rest of the nucleotides are part of introns and are removed from mRNA after transcription.
Answer:
Oxygen atoms in water molecules are also attracted to hydrogen atoms in other water molecules.
Explanation:
If you are referring to the picture attached and the choices given:
- Hydrogen atoms in water molecules are only attracted to other hydrogen atoms.
- Oxygen atoms in water molecules are attracted to both oxygen atoms and hydrogen atoms.
- Oxygen atoms in water molecules are also attracted to hydrogen atoms in other water molecules.
- Hydrogen atoms in water molecules are only attracted to an oxygen atom in the same water molecules.
What you can see there is what we call hydrogen bonding. The oxygen atoms are attracting the hydrogen of other water molecules. This type of bond forms in liquid water. Oxygen atoms of a water molecule are kind of negatively charged and can attract the partially positively charged hydrogen atoms of other water molecules.
Answer:
Iron.
Explanation:
The individual should take the proper balanced and nutrition dirt for the proper growth and development of an individual. This also reduces the chances of disease in an individual.
Milk is a good source of almost all the nutrients and proteins. But if Alexandra consume all protein from the milk she might have deficiency of the iron in her body. The milk do not contain or contain small amount of iron and dependency only on milk causes iron deficiency in the body.
Thus, the answer is iron.
