RNA synthesis depends on RNA polymerases (RNAPs). This is the enzyme that faciliates copying a sequence of DNA which is the first step leading to gene expression. This multi-step process is important for researchers to understand especially in relations to studying how genetics influence disease processes.

terry physics pushes a 75kg lab cart so that is accelerates from rest with a velocity of 4.4m/s in 3.1 secounds. what is the for

svetlana [45]

106.5N

Explanation:

Given parameters:

Mass of cart = 75kg

Velocity = 4.4m/s

time taken = 3.1s

Unknown:

Force = ?

Solution:

To solve this problem, we are going to apply newton's second law of motion. The law states that "the acceleration of a body is directly proportional to the force on the body and inversely proportional to the mass".

F = m x a

F = force on body

m = mass of body

a = acceleration of the body

But we know that acceleration is the change in velocity with time of a body;

a = $\frac{change in velocity }{time}$

F = m x $\frac{V}{t}$

V is the velocity

t is the time taken

F = $\frac{75 x 4.4}{3.1}$ = 106.5N

Which method of collecting data would provide the most accurate information about how an ecosystem is being affected by human de

saw5 [17]

Answer: The population size is recorded for each species present in the construction area before and after the building is completed
This method of collecting data will provide the most accurate information about how an ecosystem is being affected by human development because it studies a lot of different species both before and after the construction.
