Sheila and Jerome are lab partners. They have the following materials at their table:

1 square of aluminum foil, 1 stirring rod, 1 beaker of water, 1 scoop of copper II chloride salt (blue color)


Step 1:Jerome adds all the salt to the water and stirs. The salt crystals disappears and the liquid solution turns a clear blue.

Step 2: Sheila tears up the aluminum foil into small pieces.

Step 3: Jerome dares her to put the foil in his beaker. They see the edges of the foil turn a rusty orange. As they stir, the beaker becomes warm to the touch and a vapor begins to rise from the surface of the beaker. Within a few minutes, the foil has disappeared and the liquid is now clear. There are orange-rust colored flakes floating in the liquid.


Q: Jerome claims that when the salt was added to the water it turned blue and the foil disappeared, these were chemical changes. He went on to explain that the chemical change was due to the fact that the atoms were speeding up. Sheila disagrees claiming that 1 is a physical change and 1 is a chemical change and Jerome’s evidence is incorrect. Who is correct, Jerome or Sheila?

List the communities in a successional sequence of secondary succession?

Answers

Secondary succession occurs in areas where a biological community has already existed but some or all of that community has been removed by small-scale disturbances that did not eliminate all life and nutrients from the environment.

The given communities can be ordered in the secondary succession as grass, shrubs, small trees and large tress.

What is secondary succession ?

The life cycle of a plant is characterized by secondary ecological succession. Secondary succession, in contrast to primary succession, is a process initiated by an occurrence such as a forest fire, harvesting, hurricane, etc. that reduces an already established ecosystem (such as a forest or a wheat field to a smaller population of species.

As a result, secondary succession occurs on preexisting soil, whereas primary succession typically takes place in a location lacking soil. Many elements, including trophic interaction, starting composition, and competition, might influence secondary succession. Trade-off with colonization

Therefore, the given communities can be ordered from the small level to higher level as grass, shrubs, small trees and large tress.

What is the name of the tide when the sun, moon, and earth are all aligned, causing the greatest pull for highest and lowest tides?
Question 10 options:

Low tide


Spring tide


High tide


Neap tide

Answers

Answer:

spring tide

Explanation:

When the sun, moon, and Earth are in alignment (at the time of the new or full moon), the solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very low, low tides — both commonly called spring tide

Answer:

Whenever the earth, moon and sun are aligned, the gravitational pull of the moon is augmented by the gravitational pull of the sun, causing larger than average tidal ranges — meaning especially high high tides and very low low tides. These extreme tides are called “spring tides.”

(They say he cheats at cards.)And his footprints are not found in any file of Scotland Yard's.And when the larder's looted, or the jewel-case is rifled,Or when the milk is missing, or another Peke's been stifled,Or the greenhouse glass is broken, and the trellis past repair -Ay, there's the wonder of the thing! Macavity's not there!And when the Foreign Office find a Treaty's gone astray,Or the Admiralty lose some plans and drawings by the way,There may be a scrap of paper in the hall or on the stair -But it's useless to investigate - Macavity's not there!And when the loss has been disclosed, the Secret Service say:`It must have been Macavity!' - but he's a mile away.You'll be sure to find him resting, or a-licking of his thumbs,Or engaged in doing complicated long-division sums.Macavity, Macavity, there's no one like Macavity,There never was a Cat of such deceitfulness and suavity.He always has an alibi, and one or two to spare:At whatever time the deed took place - MACAVITY WASN'T THERE!And they say that all the Cats whose wicked deeds are widely known(I might mention Mungojerrie, I might mention Griddlebone)Are nothing more than agents for the Cat who all the timeJust controls their operations: the Napoleon of Crime!
