Answer:
Prophase 1
Explanation:
In prophase 1, homologous chromosomes pair up and exchange sections of DNA in a process called crossing over.
The highest point the medium rises to and a trough is the lowest point the medium sinks to.
Answer:
Blastocyst,Blastoderm
Explanation:
The blastula is made up of a hollow spherical layer of cells, referred to as the blastoderm which surrounds a yolk or fluid-filled space called the blastocele or blastocoel. In most mammals, including humans, the structure formed next is the blastocyst, a mass of inner cells that are distinct from the blastula
The benefits are Beaches are better protected against erosion.
Trenches created in the ocean encourage species growth.
WhatWhat are the advantages and disadvantages of beach nutrition?
Since nutrition just reduces the consequences of erosion and does not address its origins, it is usually a recurrent procedure. An agreeable setting lengthens the time between nutrient projects, cutting costs. On the other hand, a high rate of erosion might make nutrition unprofitable.
Sea turtles and rare and endangered birds alike depend on healthy beach and dunes systems. Important wildlife habitat areas that are endangered by erosion are provided by maintaining nourished beaches.

A good extraction solvent should have a strong solubilizing capability for the compound of interest, it should be immiscible or only weakly misciblewith the matrix solvent ( the first solution or mixture containing the compound from its natural source, e.g., water/ether. water/ chloroform, etc. If possible the extraction solvent should be non-flammable, non-toxic or of low toxicity, reasonably volatile, and of low eco-impact. Inexpensive and available, of high purity , and shelf stable. If one is determining the compound of interest by UV/Vis spectrophotometry or fluorescence, the solvent should have extremely low absobance or emission at the wavelength of analysis
• high solubility for the solute and low solubility for the carrier liquid.
• density difference vs. the carrier liquid greater than 150 kg/m. ...
• mid-level interfacial tension (5–30 dyne/cm)
• high resistance to thermal degradation.
