Explanation:
Answer:
Yes, photosynthesis is a chemical change
Explanation:
Photosynthesis is the process through which plants convert light energy into chemical energy. Here is the chemical reaction involved: water and carbon dioxide combine to form glucose and oxygen. Since new chemical species are formed, photosynthesis is clearly a chemical change.
<span>Serum potassium, phosphate, calcium
and magnesium concentrations will not directly suggest intrarenal acute renal
failure. The confirmatory test for acute renal failure is the ratio of serum
creatinine and blood urea nitrogen (BUN). </span>They serve as indicators of decrease
renal function when there is a small amount of waste products primarily blood
urea nitrogen and creatinine found in the blood of the patient. Moreover, the
decline measurement of these two serum in the blood will be use for the
diagnosis of intrarenal acute renal failure.
The answer is; Evaporation and condensation
When water turns from a liquid phase in the oceans to gas (water vapor) in the atmosphere, this is called evaporation. When the water vapor (gas ) cools in the cooler upper atmosphere to water droplets (that form clouds), this is called condensation. Evaporation is an endothermic process while condensation is an exothermic process.
SPINDLE FIBERS
In Mitosis, Spindle Fibres form at opposite poles of the cell and meet at the equator. Collectively, they form a spindle-shaped structure which attach to Centromeres.
CENTROSOMES
The organelle located near the nucleus in the cytoplasm,
composed of 2 centrioles that divides during S Phase
Centrioles are surrounded by a mass of proteins (Pericentriolar Material (PCM))
Migrates to opposite poles of the cell during mitosis
Involved in the creation of spindle fibres
CHROMOSOMES
A threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
Centromeres
The constricted region joining the two sister chromatids that make up an X-shaped chromosome. It also serves as the point of attachment for spindle fibers when the spindle fibers are pulling the chromosomes toward the centrioles (situated on opposite poles in a cell) prior to cytokinesis.
