Answer: The drug abuse is influenced by the environment and exerts influence on the gene expressions.
Explanation:
The genetic make up of the person is decides, which genes will be expressed and develop a trait in an individual. But this genetic expression can be influenced by the environmental factors like food, exposure to sunlight, and others. This study which relate environment with the genetic make up is called epigenetics. No person is drug addict by birth but the consumption of drug can influence the genetic make up and traits in a abuser. So here, the environment is influencing the genetic basis of a abuser.
Your heart rate before exercising would probably be the at rest rate of say about 50-60 beats per minute whereas immediately after exercise it could easily be say 115-130 and depending on age there is an optimum heart rate for each age range which decreases somewhat with age. Timing for a full minute your heart rate is best as it will give the actual count whereas if you just do it for 10 seconds and then multply by 6 it would assume it will be consistent whereas it could decrease during the minute so the actual measured count for a full minute is more accurate.

See the answer below
Explanation:
Recall that: <em>Water potential = pressure potential + solute potential</em>
Since the system is an open one;
<em>Water potential = solute potential = -iCRT</em>
i = number of particles the molecle will make in water (1)
C = molar concentration
R = Pressure constant = 0.0831 liter bar/mole K
T = temperature in kelvin = 22 + 273 = 295 K
To calculate water potential on side A:
C = 1 M
Water potential = - (1 x 1 x 0.0831 x 295) = -24.51 bars
For side B:
C = 2 M
Water potential = - (1 x 2 x 0.0831 x 295) = -49.03 bars
b.
<em>Since side A has higher water potential than side B, water will flow from side A to side B until equilibrium is established between the two sides. Water always flows from the region of higher water potential to the region of lower water potential.</em>

Answer:
The primary reasons why LED fixtures emit a lot of red are 1) red LEDs are among the most efficient at converting electricity into photosynthetic photons, 2) chlorophyll strongly absorbs red light, thus it is effective at photosynthesis, and 3) red LEDs are relatively inexpensive
Answer:
The ideal temperature for Radish seed germination is between 18°C and 29°C. Air and soil temperature ranges affect Radish seed germination. Air temperatures of about 10 to 18°C will give the best results
