A cell is placed in a solution of sugar and water. The cell has a sugar solution made-up of 15mg of sugar and the outside has a

sugar solution made-up of 20mg of sugar. The cell membrane is permeable to both water and sugar. Which statement MOST accurately describes what will happen to the cell.

Answer:

When sugar molecules are added to side B, it becomes hypertonic because there are more sugar molecules than side A. Water moves across the membrane, from the less concentrated (hypotonic) side A to the more concentrated (hypertonic) side B, until the concentration is equal on both sides.

How does air pressure affect weather
UNO [17]

Answer:

<em>Hewo, Kiluawa (sorry if i spelled it wrong) </em>

Explanation:

High Pressure

Basically, high pressure occurs in an area if the atmosphere over that particular area becomes heavier. As a result, the heavy air above will come down to the Earth’s surface. And the air present in that area will move away to create space for the heavy air.

Commonly, the warmer months experience high pressure. You’re more likely to enjoy a comparatively dry and stable weather pattern in those months. Besides, you’ll find the skies in high pressure areas very clear. You’ll also feel a gentle breeze there that will cool down the surrounding areas.

Low Pressure

On the other hand, the air above a low pressure area is comparatively much lighter than the air below. As the heavy air on the Earth’s surface cannot go further below, it pushes away the lighter air above. As a result, a vacuum is created on the surface level and the air in the surrounding areas rushes towards it to fill up the void space.

Meanwhile, the rising air starts to cool down and form clouds in the sky. These clouds then come down to the Earth in the form of rain. Sometimes, snow is also formed depending on the temperature of the surrounding areas.

In general, colder months of the year experiences more low pressure situations. By now, you probably can guess why. The cold air on the surface level is heavier than the air above. And these low pressure areas are the reasons behind unstable weather conditions like snow, ice, rain, storm, etc.

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.
