The chemical energy in food is converted to potential energy stored in the body which is then converted to mechanical and kinetic energy, as a result of motion while running then to heat energy.
<u>Explanation</u>:
- The chemical energy in nourishment is changed over to potential energy stored in the body which is then changed over to mechanical and kinetic energy, because of movement while running then to heat energy.
-
The energy bar eaten by Sheila has chemical energy bolted up inside it. This chemical energy is changed over to mechanical energy in a type of potential and kinetic energy and this is changed over to heat energy as the run progresses. Along these lines, the energy changes are chemical energy to mechanical energy [kinetic and potential] and finally to heat energy.
Isotonic solution- refers to two solutions having the same osmotic pressure across a semipermeable membrane

Answer:
2.82 g
Explanation:
Step 1: Write the balanced precipitation reaction
3 Ba(NO₃)₂ (aq) + Al₂(SO₄)₃ (aq) ⇒ 3 BaSO₄(s) + 2 Al(NO₃)₃(aq)
Step 2: Calculate the reacting moles of Ba(NO₃)₂
45.0 mL (0.0450 L) of 0.548 M Ba(NO₃)₂ react.
0.0450 L × 0.548 mol/L = 0.0247 mol
Step 3: Calculate the moles of Al₂(SO₄)₃ that react with 0.0247 moles of Ba(NO₃)₂
The molar ratio of Ba(NO₃)₂ to Al₂(SO₄)₃ is 3:1. The reacting moles of Al₂(SO₄)₃ are 1/3 × 0.0247 mol = 8.23 × 10⁻³ mol
Step 4: Calculate the mass corresponding to 8.23 × 10⁻³ moles of Al₂(SO₄)₃
The molar mass of Al₂(SO₄)₃ is 342.2 g/mol.
8.23 × 10⁻³ mol × 342.2 g/mol = 2.82 g
Answer:
Option (1)
Explanation:
Trace fossils are defined as those traces such as the impressions and signs of ancient remains of an organism, that are found over relatively softer sediment.
These play a very important role in the field of paleontology as it provides information about the ancient organism that lived in the past in a particular location.
Some of the examples of trace fossils are track and trails, burrows, footprints, cast and mold.
Shrimp burrows are an example of trace fossils, which are made by the marine organisms named shrimps, that are usually found at the bottom of the ocean.
Thus, the correct answer is option (1).
