Where do living things obtain phosphorus from?
Bumek [7]

Answer:

Plants take up inorganic phosphate from the soil.

Explanation:

Phosphorus moves in a cycle through rocks, water, soil and sediments and organisms. Over time, rain and weathering cause rocks to release phosphate ions and other minerals. This inorganic phosphate is then distributed in soils and water. Plants take up inorganic phosphate from the soil.

A car with a mass of 1,324 kilograms, traveling at a speed of 20 meters/second, crashes into a wall and stops. What is the kinet
Leto [7]

The kinetic energy of a car with a mass of 1,324 kilograms, traveling at a speed of 20 meters seconds is 264800J.

<h3>How to calculate kinetic energy?</h3>

The kinetic energy of a moving car can be calculated using the following formula:

K.E = ½ × m × v²

Where;

  • K.E = kinetic energy
  • m = mass
  • v = velocity

K.E = ½ × 1324 × 20²

K.E = 264800J

Therefore, the kinetic energy of a car with a mass of 1,324 kilograms, traveling at a speed of 20 meters seconds is 264800J.

What’s the answer for number 4?
dimaraw [331]
I would like to say b but I’m not 100% sure. Some proteins are regulated by the non-covalent bonding of smaller molecules like amino acids and nucleotides and those cause a change in the conformation and whenever a protein is produced a copy of the DNA is made. DNA is what holds the information for making all the different proteins in your body. But why I think it’s b is by changing the sequence of nucleotides in the DNA molecule it can change the amino acids in the final routine and create a protein malfunction. So yeah I think it’s be because by changing the sequence of nucleotides it
