3. Psychologists like to experiment on other organisms in their immediate environment, so Jenny
decided to perform a few experiments on her kitty, Precious. Jenny had a little clicker that makes
a loud 'CLICK' sound. She walked around the house, randomly clicking it while Precious rested in
the living room. Then Jenny sat down with Precious, and used the flash on her camera to flash a
bright light at the same time she clicked. Precious blinked because of the flash, and looked mildly
annoyed. Jenny repeated this process with her 4 times, then clicked the clicker, without using the
flash. She still blinked!

Which evidence supports the claim that Earth’s continents formed during Precambrian time?
Compaction caused rock to cool and rise to form pieces of crust.
Earth collided with a large object and threw material onto Earth’s surface. Collisions with comets added land masses to Earth’s surface.
Earth’s surface cooled, causing rocks to cool and harden.
Answer:
Earth’s surface cooled, causing rocks to cool and harden.
Explanation:
explanation
The evidence that best supports the claim is ; ( D ) Earth's surface cooled, causing rocks to cool and harden
The precambrian time is the period which the earth is believed to have begin its formation, because during this period there were rocks believed to have formed from the cooled molten state of the earth and the presence of oceans also believed believed to have been formed from the cooling of water vapor which was present in the atmosphere.
Hence we can conclude that the evidence that best supports the claim is Earth's surface cooled, causing rocks to cool and harden.

COMPLETE PROTEIN:
Proteins are biological molecules that are structurally made up of monomers called AMINO ACIDS.Proteins are source of nutrients to the body as they are used for varying functions like building and repair of tissues etc. However, based on the amino acid content, proteins can be either classified as complete or incomplete. Complete proteins are food sources that consists of the nine essential amino acids. The body cannot synthesize essential amino acids on its own, and therefore, require external sources of them.Learn more at: https://brainly.com/question/24231901?referrer=searchResults

What's the main reason why cell specialization is important?
Question 12 options:
It allows multicellular organisms to perform many distinct functions.
It allows unicellular organisms to perform many distinct functions.
It generates totipotent cells.
It creates cells at a faster rate.
Answer:
It allows multicellular organisms to perform many distinct functions.
Explanation:
Cell specialization is important primarily because it allows multicellular organisms to perform many distinct functions. Cell specialization isn’t important in unicellular organisms, because it doesn’t occur. Cell specialization isn’t important primarily for creating cells faster, and it doesn’t generate totipotent cells. Rather, totipotent cells are the stem cell progenitors that allow cell specialization to occur.
It makes it possible for multicellular creatures to carry out a wide variety of unique roles. Therefore, option (A) is correct.
What is cell specialization?The transformation of a stem cell into a differentiated cell type is accomplished by a process known as cellular differentiation. Typically, the cell will transform into a type that is more specialized.
The primary reason why cellular specialization is so important is that it enables multicellular organisms to carry out a wide variety of diverse jobs. Because it does not take place in unicellular creatures, the process of cell specialization is irrelevant to their biology. The primary reason why cell specialization is not crucial is that it does not produce totipotent cells, nor does it speed up the process of making new cells. Instead, totipotent cells are the progenitors of stem cells, which are the cells that can differentiate into specialized cell types.

Why do countries not convert from the use of oil to solar energy?
Solar energy is more difficult to use than oil to make electricity.
It requires more work to use solar energy to make electricity.
Solar energy is a limited resource.
It is more expensive to create solar energy than use oil for making electricity.
Answer:
It is more expensive to create solar energy than use oil for making electricity.
Explanation:
Solar energy is a renewable source of energy from the sun. It is the most powerful and eco-friendly source of energy, however, many countries still do not use this source of energy in creating electricity. This is because the technology behind using solar energy to create electricity is very expensive in comparison with the use of oil.
In as much as solar energy is always readily available everywhere and everyday (natural), building the technology to make it generate electricity is huge. Hence, countries stick to the use of oil, which is way cheaper to operate.
