Heroin is an opioid drug composed of morphine, a natural alkaloid derived from extracts from the seeds of the opium poppy. It is for that reason that heroin is considered a semi-synthetic opioid.
- HEROIN causes euphoria followed by agitation, and is the major opioid drug of abuse.
- Heroin is a drug that causes addiction, a form of substance use disorder.
- This drug (heroin) is capable of entering the brain quickly and producing immediate effects.
- The feeling of euphoria caused by heroin is followed by a period of sedation because heroin (as well other opioids) sedates the brain.

Answer:
2.447 × 10⁴ years
Explanation:
Step 1: Given data
- Half-life of the radioactive atom (t1/2): 3,500 years
- Parent-daughter ratio ([A]/[A]₀): 1:127 (1/127)
Step 2: Calculate the rate constant
Radioactive decay follows first-order kinetics. We can calculate the rate constant (k) using the following equation.
k = ln2 / (t1/2) = ln2 / 3,500 y = 1.980 × 10⁻⁴ y⁻¹
Step 3: Calculate the time elapsed (t)
For first-order kinetics, we will use the following expression.
ln ([A]/[A]₀) = -k × t
t = ln ([A]/[A]₀)/ (-k)
t = ln (1/127) / (1.980 × 10⁻⁴ y⁻¹) = 2.447 × 10⁴ y
Answer:
The more focused the rays are, the more energy an area receives, and the warmer it is. The difference in solar energy received at different latitudes drives atmospheric circulation. Places that get more solar energy have more heat. Places that get less solar energy have less heat. :)
Explanation:
I think the correct answer from the choices listed above is option C. This certain occurrence is an example of genetic engineering. In this case, the genetic makeup of the cabbage is being altered in order to improvements to the plant for its survival. Hope this answers the question.
Atoms are the smallest unit of matter. Atoms of isotopes of the same element contain the same number of protons.
<h3>What are isotopes?</h3>
Isotopes are atoms of the same element which have different numbers of neutrons but the number of protons and electrons remains same.
As the isotopes of the atom have the same number of protons, so, their atomic number will also be the same.
Thus, it can be concluded that atoms of isotopes of the same element contain the same number of protons.
