2. Adaptation is an organism changing to better themselves in a certain environment.
3. These moths were adapted to blend into their surroundings, so as to not be seen by predators.
4. Because of the pollution from the city, the tree’s bark turned from a lighter shade brown to a darker shade brown.
5. A majority of the moths were a lighter gray. With the changing color bark they were seen more by predators.
6. Adaption caused the first darker moths to appear because they learned they needed to blend into the new tree bark color.
7. The change from light to dark gray was very needed for moths. It explains natural selection for those moths who did not adapt to different color gray. Adapting the new tree bark color helped moths been less seen by predators therefor keeping their species more alive.

Answers
Answer:
6, 5, 4, 2, 1, 3
Explanation:
Transcription refers to the process of the formation of RNA molecules from DNA molecules using DNA strands as a template.
Only one strand out of two DNA strands is involved in the process and the strand is known as coding strand which runs in the direction of 5' to 3'.
The process of transcription takes place in the following sequence:
1. Helicase enzyme binds to the DNA and unzips the two strands of DNA. This opens the helices of the DNA and the DNA gets open.
2. RNA polymerase binds to the promoter attached to the DNA and forms the single strand.
3. The RNA nucleotides form complementary base pairs with the DNA and the RNA strand. A new complementary strand is made using complementary base pairing.
4. DNA helicase unzips the DNA and RNA hybrid.
5. The DNA and RNA get separated and the mRNA molecule formed in the nucleus exits the nucleus.
6. The two-strand of DNA is again joined via complementary base-pairing rule.

What can scientists infer about the period of very early Earth from the fossilized remains of trees found under a lake?
Answers
Answer:There is a theory that terrestrial plants evolved from aquatic plants through a process of natural selection. Thus, by finding fossils of plants under the river, scientists may conclude that this theory is correct and that these fossils represent the ancestors of terrestrial plants.
The emergence of plants that survive on earth is a very important milestone for the planet, it is believed that these plants have evolved from green algae called Chlorophyta that have survived in marshy areas that had alternating periods of flooding and drought.Then the discovery of these fossils, through scientific experiments may conclude that the theory is correct
Explanation:
Answer:
The fossil record is the record of life on earth preserved in rock as fossils. The fossil record provides evidence of where types of plants and animals lived, how long they lived, how they died, and how they changed. It also tells us about Earth’s early environment and how it changed. The fossil record helps determine the age of rock formations by looking at how deep the fossils are buried in the rock. When a fossil is found above another fossil in a rock formation, the deeper fossil are considered older.

What is the speed of a wave with a frequency of 6oHz and a wavelength of 20m
Answers
Answer:
speed = 1200 m/s
Explanation:
given data
frequency = 60 Hz
wavelength = 20 m
solution
we get here speed of a wave that is express as
speed = Frequency × wavelength ...............................1
put here value and we get speed
speed = 60 × 20
speed = 1200
so speed of a wave is 1200 m/s

Jacque is hiking in the mountains and sees a very large and colorful rock layer. It looks different than the surrounding rock layers. What is the best way for Jacque to investigate what the environment was like when this rock layer was deposited?
Jacque could measure the height of the rock layer.
Jacque could check if the rock layer has fossils in it.
Jacque could look at the color of the surrounding rock layers.
Jacque could chip off a chunk of rock from the rock layer and smell it.
Answers
Answer:
Check if the rock layer has fossils in it.
Explanation:
The rock layer from the inside out and the fossils will tell you how old the rock is.
Jacque could check if the rock layer has fossils in it, as the presence and types of fossils can often provide clues about the environment in which they were formed.
What can a rock layer tell about the environment?To investigate what the environment was like when a rock layer was deposited, there are several approaches that can be taken:
Look for clues in the rock layer itself: The rock layer itself can often provide clues about the environment in which it was formed. For example, the presence of certain minerals or fossil types can indicate the presence of specific conditions, such as warm or cold temperatures, or a marine or terrestrial environment.
Examine the surrounding rock layers: The rock layers above and below the rock layer of interest can provide additional context and clues about the environment. For example, if the surrounding layers are sedimentary rocks, such as sandstone or shale, it may indicate that the area was once covered by water.
Use rock dating techniques: As mentioned earlier, techniques like radiometric dating and relative dating can help determine the age of a rock layer and provide insight into the environment that existed at the time it was formed.
Conduct additional analyses: Depending on the type of rock and the questions being asked, it may be possible to conduct more detailed analyses, such as chemical or isotopic analyses, to gather further information about the conditions under which the rock formed.
Consider the current location of the rock layer: The current location of the rock layer can also provide clues about the environment in which it was formed. For example, if the rock layer is found in a mountain range, it may have formed in a tectonically active area, while a rock layer found in a flat, low-lying area may have formed in a more stable environment.

Sleet is precipitation made of small particles of ice. How does sleet form?
Answers
Answer:
Sleet is pellets of ice that form when snow falls into a warm layer and melts into rain. The rain then falls into a freezing layer of air that is deep enough to refreeze the raindrops into pellets. Sometimes the snow does not completely melt and the partially melted snowflakes refreeze into snow pellets.:
hope this helps!
Answer:
There must be a layer of air near the ground whose temperature is below freezing, where water turns to ice. Above this layer of freezing air must be a layer of warmer air. As snow falls through the warm air, it melts or partially melts into raindrops. It forms sleet before it reaches the ground.

Answers
Answer:
Human activities increases the concentration of oxygen in the atmosphere.
Explanation:
Human is not responsible for the balance of oxygen gas in the atmosphere because human takes oxygen from the environment for the production of energy in the process of respiration. Plants are the key factor for maintaining the oxygen concentration in the atmosphere. Human activities are the main reason of increasing carbon-dioxide and other harmful gases in the atmosphere and increases the air pollution and change in climate occurs.
