Answer:
Explanation:
well different kinds of drugs can affect neuron activity an example is if you take pain pills it blocks the neurons that sense pain other drugs can give you high levels of dopamine, dopamine is the hormone that makes you feel good. that is why drug addictions are serious, and many cannot stop the addiction because it makes them feel good. and if you take the same dose over time your body gets a tolerance to the drug and you need a higher dose every time to get the same feeling and that can lead to an overdose or even death.

a, the amount of grass would increase
Explanation:
if the grasshopper is the one in this diagram eating the grass, and suddenly there were fewer grasshoppers to do that, the grass would increase because more of it can grow without being eaten

How Biochemistry and Biometry are interrelated to each other?
Answer: The biochemistry is the scientific study of the chemical substances.
Explanation:
In biochemistry the chemical composition of the chemical substances and their involvement in the vital body processes in living organisms is studied. The function and structure of the chemical compounds and their associated biomolecules is studied thoroughly. The biochemistry is studied at the molecular and the atomic level. In biometry the structural dimensions of the biomolecules is studied. This way the biochemistry is linked with biometry.
Which characteristic is not common to both prokaryotic cells and eukaryotic cells?
what is the cause and effect of stop codone mutation?
Answer:
Nonsense mutations occur when a premature nonsense or stop codon is introduced in the DNA sequence. When the mutated sequence is translated into a protein, the resulting protein is incomplete and shorter than normal. Consequently, most nonsense mutations result in nonfunctional proteins.

A body cell has been growing and synthesizing proteins. In the nucleus of this body cell, DNA replication is taking place, and a copy of the cell's genetic material is copied. Which of the following is the best conclusion you can make about the life cycle of this cell?
The best conclusion you can make about the life cycle of this cell is that the cell is in the S phase of interphase and will move next to the G2 phase.
S phase (Synthesis Phase) is the phase of the cell cycle in which all of the chromosomes (DNA) are replicated within the nucleus. During this phase, the DNA is effectively doubled as each chromosome contains two sister chromatids. After the S phase, the cell enters the G2 phase where various proteins (such as microtubules) are synthesized.

Convection occurs because heated material becomes ____________________. A less dense and rises B denser and rises C denser and sinks D less dense and sinks
Answer: A less dense and rises
Explanation:
Convection is a type of heat transfer happens when there is a movement of fluid (liquid or gas) in which convection currents are produced due to the movement of hot fluid upwards and cold fluid downwards. This happens as the density of hot fluid decreases due to presence of less number of mmolecules per unit volume. As the hot liquid becomes less dense, it starts moving upwards.
Thus convection occurs because heated material becomes less dense and rises.
When air has reached its dew point
A) Air has to be cold
B)Air can hold more water
C)Air is saturated
D)Air has low humidity
Answer:
When air has reached the dew-point temperature at a particular pressure, the water vapor in the air is in equilibrium with liquid water, meaning water vapor is condensing at the same rate at which liquid water is evaporating.....

Would you expect the stomata of a desert cactus or the stomata of a water lily plant to close during the day?
The stomata of a desert cactus will close during the day.
STOMATA:
The stomata (singular- stoma) are structures on the leaves of a plant that helps in gaseous exchange i.e. entry and exit of CO2 and O2 gases. The stomata, however, when opened allows the passage of water vapor from the plant. Hence, plants utilize the opening and closing of stomata to regulate water loss. Desert cactus is a xerophytic plant meaning that they can survive in low water conditions. One way they adapt to their desert environment, which is characterized by low humidity, is by the closure of their stomata during the day. Therefore, the stomata of a desert cactus will close during the day.Learn more at: https://brainly.com/question/3387375?referrer=searchResults

Alejandro wants to find the speed of his car in meters per second. His car traveled 50 cm. It took 5 seconds to travel 50 cm. How fast did his car go?
Answer:
0.1m/s
Explanation:
Speed can be calculated using the formula;
Speed (m/s) = distance (m) ÷ time (s)
According to the information provided in this question, Alejandro's car travels 50cm in 5seconds i.e. the distance traveled is 50cm and the time is 5s.
However, the question requires the distance to be in metres (m). We, therefore, need to convert 50cm to m by dividing by 100.
100cm = 1m
50cm = 50/100
= 0.5metres.
Speed = 0.5/5
Speed = 0.1m/s.
The car travels as fast as 0.1m/s.
