A gas delivers 874 J of heat and then has 159 J of work done upon it. The change in internal energy of the gas is
Nesterboy [21]

The change in internal energy of this gas sample is equal to: c. 715 J.

<u>Given the following data:</u>

  • Quantity of heat = 874 J.
  • Work done = 159 J.

<h3>What is the First Law of Thermodynamics?</h3>

Mathematically, the the First Law of Thermodynamics is given by this formula:

\Delta H = Q-W

Where;

  • \Delta H is the change in internal energy.
  • Q is the quantity of heat.
  • W is the work done.

Substituting the parameters into the formula, we have;

\Delta H =874-159\\\\\Delta H = 715

Change in internal energy (ΔH) = 715 Joules.

When heart muscles cells are deprived of oxygen, the heart still pumps. what must the heart cells be able to do? transform lacta
katrin2010 [14]
The heart cells must be able to continue aerobic metabolism when skeletal muscle cannot. Aerobic metabolism is a part of cellular respiration and involves body cells making energy through glycolysis, the citric acid cycle, and the electron transport/oxidative. It is done in the heart at a rate below 85% of maximum heart rate and does not use vigorous muscle contraction. fatty acids , ketone bodies and carbohydrates are the primary substrates of the heart metabolized to generate ATP. The metabolic demands of the heart are the largest than any other organ in the body, and normal cardiac metabolism is required to fuel contractile function and viability.

Juliette [100K]

The generic name of poisonous chemicals, very often used in commercial agriculture that are used to kill organisms that either reduce the yield of crops or are harmful to animals are pesticides.

Pesticides are the chemicals used to kill the pests affecting the growth and yield of the crops. Pesticide is a broad term covering various small terms according to the pest being killed. For example insecticide, nematicide, avicide, rodenticide, bactericide, etc. Some chemicals used as pesticides are boric acid, Acephate, Deet, Propoxur, glyphosate, etc.

Commercial agriculture means growing of crops so as to sell them in the market to be utilized by the wide population of any area. Any crop can be grown at the commercial level. These crops do not reach the customers directly by the farmers, instead they are sold to whole-sellers first.

DNA contains instructions for making the different molecules that a cell needs to grow and function. For example, _______ is mad
lions [1.4K]

DNA contains instructions for making the different molecules that a cell needs to grow and function. For example, proteins are made by translating mRNA.

<h3>What is DNA and what is its function?</h3>

DNA is the structure responsible for transmitting all genetic characteristics — such as eye, skin and hair color, physiognomy, among others — in the process of reproduction of living beings. In this way, the main function of DNA is to carry information contained in its sequences, called genes.

DNA is made up of two chains of polynucleotides (strand), which are made up of several nucleotides. Nucleotides are joined together by bonds called phosphodiester (phosphate group linking two sugars of two nucleotides).
