Answer: 2.6 x 10^13 m/day
Work:
There’s 86,490 sec per day, so
(3.0 x 10^8 m/s)(86,400 s/1 day) = 2.6 x 10^13 m/day

Suppose you found a fossil of a clam shell what can you conclude about the once-living organism and how it became a fossil?
Stolb23 [73]

Answer:

Identifying the fossil is the first step. We have already identified this fossil as a clamshell. We know clam are from the sea, but if you didn't, you could conclude this from knowing where you found the fossil (likely near the beach). Discovering where it is can also lead you to a conclusion on it's arrival as a fossil, perhaps washed up on shore or buried by an animal.

A student inoculates a gelatin tube and places it at 37C for the week. When he comes back he takes the tube out of the incubator
ycow [4]
<h2>Gelatin </h2>

Explanation:

Gelatin is a differential medium which tests the ability of an organism to produce an exoenzyme, called gelatinase (this enzyme hydrolyzes gelatin)

When gelatin is at a temperature below 32°C (or within a few degrees thereof), it is a semisolid material and at temperatures above 32°C, it is a viscous liquid

When gelatin is broken down, it can no longer solidify and if an organism can break down gelatin, the areas where the organism has grown will remain liquid even if the gelatin is refrigerated

No the conclusion by student is not right because the tube must be runny after incubation followed by refrigeration to be considered gelatinase positive

Assignment: 01.03 Transformation of Energy
trasher [3.6K]

The energy transformations that occur in the given devices are as follows:

  • Windmill - mechanical energy to electrical energy
  • Flashlight - electrical energy to light energy
  • Microwave - electrical energy to heat energy
  • Firecracker - chemical energy to heat, light, and sound energy
  • Bicycle - Chemical energy to mechanical energy
  • Battery - chemical energy to electrical energy

<h3>What is energy transformation?</h3>

Energy transformation refers to the processes by which one form of energy is transformed into another form.

The law of conservation of energy guides the various energy transformations that occur in the universe.

The law of conservation of energy states that energy is neither created nor destroyed but can be transformed from one form to another.

The energy transformations that occur in the given device are as follows:

  • Windmill - mechanical energy to electrical energy
  • Flashlight - electrical energy to light energy
  • Microwave - electrical energy to heat energy
  • Firecracker - chemical energy to heat, light, and sound energy
  • Bicycle - Chemical energy to mechanical energy
  • Battery - chemical energy to electrical energy

In conclusion, energy transformations occur according to the law of conservation of energy.
