Answer:

Earth's atmosphere is a layer of gases surrounding the planet Earth and retained by the Earth's gravity. It contains roughly 78% nitrogen and 21% oxygen 0.97% argon and carbon dioxide 0.04% trace amounts of other gases, and water vapor. This mixture of gases is commonly known as air.

Answer:

Atmosphere.

Explanation:

Earth is the only planet where the environmental conditions are favorable to support life. Different layers of the earth are atmosphere, geosphere, biosphere and hydrosphere.

Atmosphere surround the earth like the blanket and protect the organisms from the harmful sun rays. Atmosphere is the envelope of all the gases that surrounds the earth. Atmosphere is important for the maintenance of life on the planet earth.

Thus, the correct answer is option (B).

RNA sequencing technology has been used largely in creating clones.

<h3 /><h3>What is RNA sequencing?</h3>

RNA sequencing (RNA-Seq) makes use of high-throughput sequencing techniques to shed light on a cell's transcriptome.

Numerous RNA biology topics, such as single-cell gene expression, translation (the translatome), and RNA structure, can be studied using RNA-seq techniques (the structurome). Exciting new uses, such as spatial transcriptomics, are being investigated (spatialomics).

<h3>The steps in a typical RNA-sequencing experiment are as follows:</h3>
  1. Design experiment: Plan the experiment.
  2. Preparation of RNA. Purify and isolate the input RNA.
  3. Library preparation. Create cDNA from the RNA and add sequencing adapters.
  4. Sequence. cDNAs should be sequenced using a platform.
  5. Analysis.

which of the macromolecules tested in this exercise (proteins, lipids, nucleic acids) were formed by dehydration reactions? expl
aalyn [17]

Large polymers are created during dehydration synthesis, which are typically referred to as biological macromolecules. These compounds include proteins, lipids, carbohydrates, and nucleic acids.

As a result, the dehydration reaction is responsible for the formation of protein, lipid, and nucleic acids.

1. Protein structure

  • Amino acid polymers form proteins. There are four different types of proteins, based on structure.
  • The amino acid sequence of a protein is represented by its primary structure, which is a linear chain.
  • The backbone (main chain) atoms of a polypeptide are arranged locally in space to form the protein's secondary structure.
  • A polypeptide chain's whole three-dimensional structure is referred to as a protein's tertiary structure.
  • The protein's quaternary structure, which is a three-dimensional arrangement of the subunits of a multi-subunit protein.

2. Lipid structure is a crucial element of the cell membrane. The structure is mostly composed of a glycerol backbone, two hydrophobic fatty acid tails, and a hydrophilic phosphate group.

3. Nucleic acids' structure: Nucleotide polymers make up nucleic acids. Each nucleotide is made up of an aromatic base with a N-atom connected to a pentose sugar with five carbons, which is then joined to a phosphate group.
