Answer:

Many biological processes happen during sleep: The brain stores new information and gets rid of toxic waste. Nerve cells communicate and reorganize, which supports healthy brain function. The body repairs cells, restores energy, and releases molecules like hormones and proteins.

<em>When you sleep, your body undergoes a series of changes that enable the rest that is vital to your overall health. Sleep allows the brain and body to slow down and engage in processes of recovery, promoting better physical and mental performance the next day and over the long-term.</em>

Which action would most likely increase the greenhouse effect?
natta225 [31]

Answer:

D. Burn more oil for heating homes

Explanation:

Encouraging people to conserve power would help weaken the greenhouse effect, not increase it. Stopping cutting down the trees in the Amazon forest would also heavily help weaken the greenhouse and not increase it. And unlike the others, using more nuclear power plants wont affect the greenhouse atfect but instead affect our air quality. Our problem is that burning coal, oil, and gas produces carbon dioxide, which adds to the supply already in the atmosphere, increasing the greenhouse effect and thereby increasing the temperature of the Earth so therefore its D.

Gold has a specific heat of 0.129 J/(g×°C). How many joules of heat energy are required to raise the temperature of 15 grams of
Elodia [21]

Answer:

\boxed {\boxed {\sf 121.905 \ J  }}

Explanation:

We are asked to find the energy given mass, specific heat, and change in temperature. Therefore, we must use this formula;

q= mc \Delta T

The mass is 15 grams and the specific heat is 0.129 J/(g×°C). Let's calculate the change in temperature.

  • ΔT= final temperature - initial temperature
  • ΔT= 85 °C- 22°C = 63°C

Now we know all the values:

m= 15 \ g \ \\c= 0.129 \ J / (g* \textdegree C) \\\Delta T= 63 \ \textdegree C

Substitue the values into the formula.

q= (15 \ g)( 0.129 \ J / (g* \textdegree C)) ( 63 \ \textdegree C)

Multiply the first numbers together. The grams will cancel.

q= (1.935 \ J/ \textdegree C) ( 63 \ \textdegree C)

Multiply again, this time the degrees Celsius cancels.

q= 121.905 \ J

<u>121.905 Joules</u> are required.

What can be interpreted about type 2 diabetes mellitus in monozygotic twins when it affects only one twin 70% of the time and af
Masja [62]

Answer:

The correct option is <em>C. Non-genetic factors can influence expression.</em>

Explanation:

Non- genetic factors can be described as factors other than genetic makeup. These factors include environmental factors and factors arising from the lifestyle of an organism.

Certain studies have shown that both the genetic as well as the non- genetic factors play a role in the development of certain characteristics.

In the above-mentioned scenario, both the monozygotic twins have diabetes but one of them is affected 70% of the time due to his lifestyle. The person might be consuming more sugars and alcohol.
