The seasons are caused as the Earth, tilted on its axis, travels in a loop around the Sun each year. Summer happens in the hemisphere tilted towards the Sun, and winter happens in the hemisphere tilted away from the Sun. ... The poles remain cool because they are never tilted in a direct path of sunlight.
Answer:
Cell differentiation is the process by which dividing cells change their function. DNA is essential in gene expression, which gives the ability of cells that are specializing to be able to adequately perform the role they are trying to carry out. It is generally understand that all the cells in our body contain the same DNA, yet they carry out different functions. The key is understanding that specific parts/combinations of the genome are activated which changes the function and shape of the cell. Additionally, if the DNA is damaged or mutated in certain areas of the chromosome, it can cause certain differentiated cells to not function properly.

Answer:
Explanation:
The United States is a power hungry country with a popular of nearly 400 million people.
Providing power to such a large population, both cheaply and reliably is not easy and takes various forms of power plants and energy methods to make sure energy is available to everyone.
When it comes to using electric driven cars, it becomes unreliable, since most electric cars have a limited range and the United States being a large country cannot currently support this.
People would rather use their cars which can provide up to 500 miles of mileage than an electric car which hardly goes 100 miles.
However, the impact of increasing fossil fuels can negatively impact biodiversity in surrounding ecosystems. Increasing carbon monoxide in the air will only lead to degradation of plant and animal life.
Answer:
You will need 10 mL of stock Tris, 15mL of stock NaCl and enough water to bring the total volume to 500 mL.
Explanation:
<u>The desired buffer contains:</u>
- Total volume of 500 mL
- Tris 30mM
- NaCl 150mM
<u>The stock solutions are:</u>
- 1.5M = 1500mM Tris
- 5M = 5000mM NaCl
We can use the formula C1V1=C2V2 to calculate the volume of each stock required to prepare the buffer.
<h2>
<u>Tris</u></h2>
- C1= 1500 mM
- V1=?
- C2= 30mM
- V2= 500 mL
1500 mM x V1 = 30mM x 500 mL
V1 = (30mM x 500 mL) / 1500 mM
V1 = 10 mL
<h2>
<u>NaCl</u></h2>
- C1= 5000 mM
- V1=?
- C2= 150 mM
- v2= 500 mL
5000 mM x V1 = 150mM x 500 mL
V1 = (150 mM x 500 mL) / 5000 mM
V1 = 15 mL
You will need 10 mL of stock Tris, 15mL of stock NaCl and enough water to bring the total volume to 500 mL.
