How can you detect hardness of water collected from different sources

1 answer:

6 0

We can detect the hardness of water taken from different sources by adding soap to it. If the soap does not form micelle in the water then it will be hard water. In simple language if the soap doesnot disslove in water then it will be soft water.

A naturalist visiting an island in the middle of a large lake observes a species of small bird with three distinct types of beak

Rzqust [24]

Answer:

a)BB*Bb

b)0:2:2(short: intermediate:long)

c)0

Explanation:

A naturalist visiting an island in the middle of a large lake observes a species of small bird with three distinct types of beaks. Those with short, crushing beaks (BB) consume hard shelled nuts, those with long, delicate beaks (bb) pick the seeds from pine cones, and those with intermediate beaks (Bb), consume both types of seeds though they are not as good at either. Assume that this difference in beak morphology is the result of incomplete dominance in a single locus gene. Which of the mated pairs below will have the best adapted offspring in a year in which most of the food available is in the form of hard shelled nuts? What would be the phenotypic ratio of the F1 generation resulting from a cross of Bb x bb(Short:Intermediate:Long)? How many offspring of an intermediate x short beak cross will have long beaks (assume 4)?

A) since the feed is put into consideration, then the offspring that is best adapted to feed on hard shelled but is to be considered. Cross-linking a gene BB with Bb is the best. If BB is said to be dominant then the offspring are produced will be short beak and intermediate beak in the ratio of 2:2 where both are suitable for feeding on hard shelled but.

B) The phenotypic ratio of the F1 generation (first generation or offspring) between Bb and bb is that there won't be a pure short beak(BB). Therefore 0:2:2 for short: intermediate: long.

C) for the intermediate and short beak crosslinking there won't be a long beak in the first generation when we limit the number offspring to four.

PLEASE HELP!!!! I WILL GIVE BRAINIEST!!!! What is the difference between weathering and erosion? How are mechanical weathering a

kicyunya [14]

Answer:

Explanation:

1. What is the difference between weathering and erosion?

ANSWER

Weathering is the physical disintegration and chemical decomposition of rocks to form soils and rocks. Weathering acts to break down earth materials.

while

Erosion is the wearing or washing away of weathered materials. Without weathering, there won't be erosion.

2. How are mechanical weathering and chemical weathering different?

Solution

Mechanical weathering is the physical disintegration of rocks. Examples are:

>Pressure release on rocks

>Biological activities

>Freezing and thawing

> Drying and wetting of rocks

Mechanical weathering helps to loosen rocks and to increase surface area of exposure of rocks.

while

Chemical weathering is the deacy and decompostion of rocks. Chemical reactions on rocks are initiated naturally in different forms. Bonds between rock molecules are broken, water can dissolve some soluble rock contents, etc, all this would lead to chemical weathering of such rocks. Chemical weathering occurs through:

>Hydrolysis

>Carbonation

>Oxidation etc.

4. How are hydrolysis and oxidation similar?

Hydrolysis and oxidation are both processes of chemical weathering. They aid in chemical decomposition of rocks.

Hydrolysis causes decompositon through the action of water. In oxidation, oxygen reacts with earth materials.

5. Explain the process of exfoliation.

Exfoliation is a physical weathering process. It accompanies pressure release on a rock surface.

Rocks overly one another and by so doing, they mount pressure on the underlying ones. The part of the bedrock close to overhead rock receives more pressure while the part far away receives little to no pressure. This differential pressure is what leads to exfoliation of rocks. Exfoliation is produced when the overlying rock is moved away and the pressure is released.

When a rock exfoliates, it breaks down into layers like an onion skin. It can create a massive feature known as an exfoliation dome. Each sheet is a product of pressure differences.

6. As waves crash into rock along the shoreline, particles of sand, shell, and other materials in the ocean water loosen tiny bits of sediment from the rock.

>>>>>>>>>This is weathering

As the waves recede, they carry the sediment away. In this scenario, which process represents weathering, and which process represents erosion?

>>>>>>>>> This is erosion
