Answer:

Answer is option C.

Water vapor form liquid water droplets on a window in the early morning is an example of condensation.

Explanation:

Evaporation is a process where water vapor is formed from liquid water. Condensation is the reverse of evaporation, where water vapor becomes liquid. It can happen when the warm air is cooled to its dew point (temperature at which condensation occurs) or when the air becomes so saturated with water vapor (it cannot hold any more water).

The condensed water in the atmosphere is known as the dew. When the temperature of the air reaches or falls below the dew point during the night, condensation occurs. This is the reason why water droplets are found on lawns, cars, and windows in the early morning.

Condensation occurs when water vapor in the warm air comes into contact with a cold surface because it reaches its dew point. This is the reason why water droplets are found outside the glasses of cold water or soda cans.

Which of the following best explains how insulin injections affect signal transduction in an individual with type 1 diabetes
Reptile [31]

Answer:

The correct answer is - option A. They serve as second messengers to regulate glucose uptake to cells.

Explanation:

Type one diabetes is a condition that is characterized as the inability to produce enough quantity or at all of the insulin by the beta cells of the pancreas. Therefore, a patient with this condition completely depends on exogenous insulin to maintain the sugar level in the blood.

Insulin is the hormone that removes the excess amount of glucose from the blood by the adipose tissue, liver cells, and skeletal muscle that uptake an extra amount of sugar. there are receptors present on the surface of the plasma membrane which binds with the insulin and acts as a secondary to regulate a cascade reaction to glucose uptake to cells.

Sequence the steps, 1–4, in the order required to create a permanent slide of human cheek cells. [1 mark] Specimen dehydrated Sp
gogolik [260]

Answer:

The correct order is dehydration, embed in wax, cut into sections, staining

Explanation:

There are certain proceedings needed to obtain stained sections of vegetable or animal tissues for their microscope observations.

These steps are:

  • Obtention of the material: The tissue is cut to an adequate size.
  • Fixation: When tissues are extracted from the organism, they suffer autolysis and putrefaction, so they need to be fixated in order to keep their cells in the best state possible. Fixation involves preserving the original morphological and molecular characteristics of the tissue. Fixation avoids autolysis, putrefaction, distortion, and retraction of cells and the tissue that could affect its volume or morphology.  
  • Dehydration. Once fixated, the fixator must be eliminated and the tissue is dehydrated by using a gradual series of solutions with alcohol in ascendant concentrations. Dehydration must be gradual to avoid tissue deformation.
  • Inclusion. To obtain thin cuts that can be observed under the optic microscope, the tissues must be included in a consistent, firm substance, that might be either hydrophilic or hydrophobic. A hydrophobic medium is paraffin wax, that provides hardness and plasticity.  
  • Cut. The tissue included in wax must be cut in slides or sections thin enough to allow the diffusion and penetration of light. A microtome is used to perform these cuts. When using paraffine for tissue inclusion, the cuts are about  5 to 20 micrometers of thickness.
  • Stain. Once the cuts are performed, paraffin wax must be eliminated. This can be done by using an organic solvent. Then the tissue must be stained. Hematoxylin and Eosin are the most common dyes. Animal tissues in general do not have any natural color, so they need to be stained to be observed.

The FitnessGram PACER Test is a multistage aerobic capacity test that progressively gets more difficult as it continues.

The test is used to measure a student's aerobic capacity as part of the FitnessGram assessment. Students run back and forth as many times as they can, each lap signaled by a beep sound. The test get progressively faster as it continues until the student reaches their max lap score.

The PACER Test score is combined in the FitnessGram software with scores for muscular strength, endurance, flexibility and body composition to determine whether a student is in the Healthy Fitness Zone™ or the Needs Improvement Zone™.
