What makes it possible for sunlight to change genetic material?
Answers
Answer:
When light hits CRY2, it changes shape and binds to its natural partner protein, known as CIB1. ... When light shines on the cells, the CRY2 protein binds to CIB1, which is floating in the cell. CIB1 brings along a gene activator, which initiates transcription, or the copying of DNA into mRNA. The melanin-assisted process creates lesions known as cyclobutane pyrimidine dimers in DNA, which can lead to mutations that cause melanoma, a type of skin cancer. These lesions are identical to the well-known genetic alterations caused when UV light directly strikes DNA

HELP! 100 POINTS! A cinder block is pulled 0.50 meters to the right in 3 seconds. What is the block's average speed to the nearest hundredth of a meter per second (m/s)?
Answers
The average speed of the blocks are 0.36 m/S.
Explanation:
Average speed is defined as the ratio of distance covered per unit time. So if it is said that blocks are pulled to 0.9 m in the right side. This means the blocks cover a distance of 0.9 m from the origin and that distance is covered in 2.5 s. Thus, the average speed can be calculated from the change in speed
with respect to time. As at time t = 0, the speed is
also zero, and at time t = 2.5 s, the speed will be
Speed =
0.9 = 0.36
2.5
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.
2.5
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.

A student makes a sandwich with several layers of bread and cheese. Then the student cuts the sandwich and says it models how a fault cuts through rock layers after the rock layers formed. Explain how the example of the sandwich relates to relative dating.
Answers
Answer:
Rock layer and sandwich layer is almost the same.
Why are rock layers are like sandwiches?
This geologic structure is called an anticline. Now gently bend your sandwich so that the layers are bowed downwards, thus creating a syncline. The presence of anticlines and synclines indicate strong forces that often form mountain ranges.
A student makes a sandwich with several layers of bread and cheese. Then the student cuts the sandwich and says it models how a fault cuts through rock layers after the rock layers formed. This example of the sandwich relates to relative dating where a geologist interprets how the earth was made by interpreting which rock layer and geological processes came first, second & third.
What is Relative Dating?Relative dating in geology is the method for determining the approximate age of a structure based on its physical relationship to surrounding geologic structures.
This is a qualitative process of determining the sequence of events. With an understanding of rock formation, geologists can sequence structures to determine the order of events and relative age.
Rock layers are formed first in flat layers. Therefore, if they're are tilted because it got squished, then the tilting came after it was laid down.The oldest layer is on the bottom and the youngest layer is on top.If the layers are cut by a fault, the cut is the youngest process.If the layers are cut or filled, from an igneous intrusion, the igneous intrusion is the youngest process.Therefore, A student makes a sandwich with several layers of bread and cheese.

What happens to the atoms that make up hydrogen fuel as it burns?
Answers
Answer:
When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.
