The correct answer is option b. They receive instructions in their DNA.
The DNA (deoxyribonucleic acid) or the genes present in the cell guides the fate of the cells during the process of cellular differentiation in the embryonic life of the multicellular organism. The signaling molecule change the genetic expression changes, by which the cells are differentiated.
Answer:
The answer would be D. Tropical Rain forests comprise only 6% of all land on Earth yet are home to nearly 50% of all the species on Earth.
Answer:
Cell Z has the greatest solute concentration
Explanation:
- The water moves from higher potential to lower potential.
- More the solute concentration in solution the lower will be water potential.
- External mechanical pressure increases the water potential.
Cell Z has more solute concentration, So it require more external pressure to equalize its internal water potential with external water potential for stopping the movement of water from high potential to lower potential.
<em>Remember the maximum potential of water is zero at standard temperature and pressure.</em>
Answer:
Here's what I get.
Explanation:
Your first problem is to figure out the formula to use.
You have an initial population P₀ that increases each year by 5 %, that is, by a factor of 1.05.
Each year, you multiply the population of the previous year by 1.05.
This gives you a geometric series, for which the general formula is
P = P₀rⁿ
P₀ = 11 500
r = 1.05, the common ratio from one year to the next
n = the number of years from now
The formula for your population is then
P = 11500(1.05)ⁿ
You must create a table with n as the independent variable and P as the dependent value.
I used Excel to create a table showing the population at half-year intervals (see below).
I also created a graph of the population growth.
You are probably aware that this is a completely unrealistic model, because the population cannot exceed the carrying capacity.
Instead, the graph will level off in a logistic growth curve as the population approaches 14 600.
