Answer:
It is fascinating to observe two distinct characters presented by the same plant. The inheritance of this plant can be determined easily by crossing the pure violets exhibiting yellow petals with dark brown marking and erect stems with violets exhibiting no markings, white petals, and prostate stems.
The F1 progeny will originate as a hybrid of the two characters. These F1 plants will then be crossed between themselves and the F2 progeny would be clearly evaluated. If the F2 plants come in the phenotypic ratio of 3: 1, then it would indicate the pleiotropic effect of the alleles found in a single locus. If any other combinations arise post crossing, it would indicate that the non-wild type phenotype is because of many distinct mutant genes.
18 g
Explanation:
Remember that 1g is equivalent to 1 ml;
1g = 1 mL
100 g = 100 mL
Therefore in an 18% NaOH solution, for every 100 mL, there is 18 g of dissolved NaOH. This is how we derive the percentage solution;
18 g / 100 g = 18%
Answer:
Mechanical Weathering
- caused by freezing and thawing of of water.
- caused by the movement of agents such as glaciers and wind.
Chemical weathering
- caused by processes such as corrosion, hydrolysis and dissolution.
- caused by precipitation reacting with minerals in the rock.
- creates new substances such as clay and salts.
Lymph is the excess blood plasma after it is filtered from interstitial fluid, when the interstitial fluid is formed. From the circulation system, after filtration, lymph is comes into to the Lymphatic system.
The Lymphatic system with its tubular vessels, is an open system. It conducts lymph between various parts of the body. It provides a route for the excess interstitial fluid to be returned back to blood.
On the other hand, Our cardiovascular system - responsible for circulation of blood - is a
closed system. Blood never leaves the veins, arteries, and capillaries.
