Scientists collect data then develop and use models to make predictions about future climate conditions.
goldfiish [28.3K]

Scientists collect ongoing data from many locations around the world. They then input this data into a mathematical or computer-based model to simulate real-world conditions.

<h3>What is climate forecasting?</h3>

Weather averages and other climatic characteristics are predicted by climate forecasts from a few weeks to a few years in advance. Such forecasts are increasingly being made using thorough models of the Earth's climate system.

Since it aids in forecasting future climate conditions, climatology and weather forecasting are crucial. The likelihood that snow and hail will reach the surface can be calculated using latitude. You may also determine the thermal energy from the sun that a location can get.

Why is it important to stain youngcultures of bacteria with<br> the grain stain?
uranmaximum [27]

Answer:

Because older cultures of gram-positive bacteria tend to lose their ability to retain crystal-violet in the peptidoglycan of their cell walls and can be confused with gram-negative bacteria.

Explanation:

Gram staining is used to differentiate between two major groups of bacteria. Gram-positive and gram-negative, these bacteria differ in the amount of peptidoglycan in their cell walls. Gram-positive bacteria have a higher amount of peptidoglycan, which absorbs the violet crystal complex used in gram staining, staining them purple/violet. Old cultures of gram-positive bacteria tend to lose the ability to retain the violet crystal and are stained by safranine, staining them red/pink and appear to be gram-negative.

Why are indexes better than simple measurements for comparing fossil specimens?
timurjin [86]
They are better because they are for comparative use for instance hair color to finger nails they both grow but onto separate parts of the body.

A tissue sampler that is being used for a medical procedure is placed inside a saline solution. Unknown to the medical team, the
solong [7]

Answer: Water will leave the cell and the cell will shrink.

Explanation:

Osmosis is the net movement of water from an area of low to high concentration of solutes through a semipermeable membrane. If none of the compartments contains solutes, then the water moves in either direction between the compartments. <u>However, if we add a solute to one of the compartments, this will affect the probability of water molecules leaving that compartment and moving into the other compartment.</u> The ability of water to move into or out of a cell is called tonicity. The tonicity of a solution is related to its osmolarity, which is the total concentration of all the solutes in the solution. A solution with low osmolarity has few solute particles per liter of solution, whereas a solution with high osmolarity has many solute particles per liter of solution. When two solutions with different osmolarities are separated by a membrane permeable to water but not permeable to solutes, water diffuses from the side with lower osmolarity to the side with higher osmolarity. So, solutions can be:

  • <u>Hypotonic</u>: The extracellular fluid has a lower osmolarity than the fluid inside the cell, it is hypotonic with respect to the cell, and the net flow of water will be into the cell.
  • <u>Hypertonic</u>: The extracellular fluid has a higher osmolarity than the cytoplasm of the cell, it is hypertonic with respect to the cell and water will flow out of the cell.
  • <u>Isotonic</u>: The extracellular fluid and the cell have the same osmolarity so there is no net movement of water.

If a cell is placed in a hypertonic solution, water will leave the cell and the cell will shrink due to the difference in pressure and may even die from dehydration.
