It happens due to the inner resistance. Resistance causes heating of tungsten filament and with more resistance, a light bulb produces more light.

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

Which type of macromolecule makes up the capsid of a virus
Elenna [48]

Protein

Proteins are the most versatile macromolecules in living systems and they play important roles in essentially all biological processes. Protein makes up the capsid of a virus. The infective extracellular form of a virus known as a virion contains at least one unique protein synthesized by specific genes in the nucleic acid of that virus. In almost all viruses, at least one of these proteins forms a shell (called a capsid) around the nucleic acid. Certain viruses also have other proteins internal to the capsid. Some of these proteins act as enzymes during the synthesis of viral nucleic acids.

What genes direct the
Valentin [98]

Answer:

a. hox genes.

Explanation:

HOX genes have the following functions:

  • HOX genes are the homeobox subset.
  • They specify the areas of the embryo's body plan along the animal head-tail axis.
  • They are encoding Hox proteins that specify the position characteristics and ensure that the right structures form at the right position in the body.
  • They regulate high-level executive genes, such as transcription factors and intracellular signaling molecules, which adhere, number, form, and growth to cells.

The vertebrates are highly preserved.

The clusters and other genes occur uninterrupted.

Evolutionary, the heterogeneous regulatory areas between the genes most previously present are larger and more preserved than those present at the other ends of the clusters.

The characteristical feature is that these are homeodomain proteins with a highly preserved area of DNA binding encoded with homeobox gens.
