Answer: D
Explanation:Heat is the form of energy that is transferred between systems or objects with different temperatures (flowing from the high-temperature system to the low-temperature system). Also referred to as heat energy or thermal energy. Heat is typically measured in Btu, calories or joules
Biomass may contribute to global climate change because certain trophic levels produce greenhouse gases.
<h3>What are greenhouse gases?</h3>
Greenhouse gases are specific types of gases that can maintain heat (solar radiation) on Earth's surface and thus increase Earth's temperature.
The ruminant animals produce methane, which is an important greenhouse gas associated with the global climate.
In consequence, the sudden increase in animal husbandry due to human activities may also increase the effects of climate change.

Attenuation is the regulatory mechanism to control gene
expression or transcription. Attenuation
was first observed in trp operon of E.Coli bacteria (commonly found at
guts of warm blooded animal). E.Coli
bacteria need tryptophan which is a kind of amino acid. The bacteria can either
take tryptophan from environment or itself synthesize by using bio synthetic
enzymes. These bio synthetic enzymes are encoded by five genes located next to
each other which we called as trp operon.
When tryptophan levels are high, then the transcription of trp
operon is controlled. This process is called Attenuation. In this process
the RNA polymerase is prematurely stopped during transcription of trp operon
which results in formation of short mRNA. Due to premature control such mRNA
doesn’t gets encoded with tryptophan biosynthesis enzymes.
Attenuation is carried out when tryptophan level is high, so
as to prevent unnecessary production of biosynthetic enzymes which are needed
to make tryptophan.

Answer:
In the cell, which organelle has the function of using oxygen in the breakdown of glucose, releasing energy and carbon dioxide?
Mitochondria plays this vital role of breaking down sugar (glucose) which serves as energy for the growth of the cell
Explanation:
Answer:
The correct answer is -
1. Blending - C
2. Straining - D
3. Detergents - B
4. Meat tenderizer (protein enzymes) - E
5. Alcohol - A
Explanation:
To extract protein from various parts of the organisms there is a scientific process that helps in successfully extract it. Organisms such as plants have a rigid cell wall that is required to be broken in order to follow the scientific process of extracting DNA and protein.
Blending use to break the cell wall of the plants such as pea cells. After breaking the cell wall one needs to dissolve the cell membrane made up of lipids with the help of soap or detergents. After the dissolving cell membrane, there is a chance to DNA gets damaged by various chemicals, therefore, alcohol is used to allow DNA to form clumps or precipitate.
Straining is used to separate the cell organelle, dissolved cell membrane from DNA and protein. Papain is a meat tenderizer and a protein enzyme that cuts or breaks the protein.
