Answer:
Given data;
Initial velocity = 0 m/s
Final velocity =?
Acceleration = 4.6 m/s^2
Times = 10 seconds
Uniform
acceleration occurs when the speed of an object changes at a constant rate. The
acceleration is the same over time. By relating acceleration to other variables
such as speed, time and distance we are able to manipulate data in many ways.
Using
the formula;
A
= (Vf – Vi) ÷ 2
4.6 = (Vf – 15m/s) ÷ 6s
4.6 × 6 = (Vf –
15m/s) ÷ 6s
27.6 m/s = Vf – 15m/s
27.6 m/s + 15m/s = Vf
Vf = 27.6 m/s + 15m/s
<span>Vf = 42.6 m/s</span>
Muscle cells require more energy than most other cells in order to function. Therefore, muscle cells would be expected to have more ________ and ________ than most other animal cells.
A) Glycogen; Mitochondria B) Peroxisomes; Fat C) Mitochondria; Starch D) Ribosomes; Glycogen E) Glucose; Nuclei.
Answer:
A) Glycogen; Mitochondria
Explanation:
Glycogen is the stored form of glucose present in the animal cells. In human beings, glycogen is mainly present in muscle cells and liver cells. Breakdown of glycogen releases glucose which in turn can be fueled into cellular respiration to produce the energy required for the muscle contraction.
The aerobic phases of cellular respiration are Kreb's cycle and electron transport chain. Both of these occur in the mitochondria. Therefore, muscle cells are rich in glycogen storage and have plenty of mitochondria to ensure the supply of ATP required for their contraction. The contraction of muscles requires lots of ATP molecules as a source of energy.
Answer:The electron transport chain is a series of complexes that transfer electrons from electron donors to electron acceptors via redox reactions, and couples this electron transfer with the transfer of protons across a membrane. The electron transport chain is built up of peptides, enzymes, and other molecules

Answer: A. The hydrogen bonds cause water to resist a change in temperature.
Explanation:
Heat of vaporization is defined as the amount of heat required to convert 1 mole of liquid to gaseous state.
Water has high heat of vaporization due to the presence of strong hydrogen bonds between hydrogen and a electronegative element oxygen. As the water molecules are strongly bonded to each other, large amount of heat is required to raise the temperature of water.
The molecules will not be able to gain enough kinetic energy and thus temperature changes slowly.
