Answer:
Eutrophication
Explanation:
Eutrophication is the name given to the natural nutrient enrichment of a shallow lake, estuary, or slow-moving stream. It is caused mostly by runoff of plant nutrients, such as nitrates and phosphates, from surrounding land.
Which of the following is an essential characteristic of an index fossil?
A) The organism lived in a very specific environment or two, such as tropical volcanic islands.
B) The organism lived for a very limited period of geologic time.
C) The fossils of the organism are exceptionally well preserved.
D) The organism lived on the land, not in the ocean.
Answer:
A. ............... ......
The organism living for a very limited period of geologic time is an essential characteristic of an index fossil, hence option B is correct.
What is an index fossil?A suitable index fossil needs to be unique or easily identifiable, plentiful, have a broad geographic distribution, and have a limited time range.
The correlation of strata and the establishment of time-scale boundaries in geology are both based on index fossils.
There are three qualities of an excellent index fossil: The fossil is easily recognized and well-known. Fossils can be discovered in many different places. The plant or animal did not survive for a sizable amount of time.
Therefore, the abundance, distribution, distinctiveness, and requirement that the fossil is constrained in geologic time are the four primary features that define a good index fossil.

What would be a good "control" setup if you were testing whether spontaneous generation can occur in a piece of bread?
Answer:
See the answer below
Explanation:
A good control set up to test whether spontaneous generation can occur in a piece of bread would be to first sterilize the bread in order to ensure that is free from any microbe and then place it in a covered sterile container. The alternate set-up would be to sterilize the bread and then place it in an uncovered sterilized container. Both set-ups will then be observed for a few days for the growth of fungi.

Once the teeth start grinding food,
Blank is produced to make food moist and slippery.
Answer:
Saliva is produced
Explanation:
Think about salivary glands.
Once the teeth begin to grind the food, saliva is produced which is a transparent liquid produced by the many glands of the mouth to make the food moist and slippery.
What is Saliva?Saliva is described as a transparent liquid produced by several glands in the mouth that is vital to one's health. Water makes up the vast majority of it. Saliva contains important components that aid in the digestion of food and repair of teeth.
Saliva is produced by the salivary glands that are found in each cheek, at the bottom of our mouth and near our front teeth, all of which are located near the jawbone. There are six primary salivary glands and hundreds of minor salivary glands in the human body.
Thus, saliva is produced which is a transparent liquid produced by the many glands of the mouth to make the food moist and slippery.

Because of hydrogen bonds between water molecules, it takes a significant amount of heat energy to make water change temperature. The amount of heat needed to make water change temperature by one degree Celsius is known as the specific heat. This number is much larger for water than it is for most other substances. It also takes a large amount of heat energy to change water from a liquid to a gas. This energy is known as the heat of vaporization. Put a drop of water and a drop of rubbing alcohol on a piece of wax paper. Which drop evaporates first? Explain your results. Make sure that you discuss the role of hydrogen bonds in your results.
Answer:
The drop of rubbing alcohol will evaporate first.
Explanation:
According to the question, HEAT OF VAPORIZATION is the amount of heat energy it takes to change a substance from its liquid state to its gaseous state. Water, as a substance, requires a high amount of this heat of vaporization for its evaporation to occur.
This property is attributed to the HYDROGEN BONDING that forms between water molecules. It takes a high amount of heat energy (heat of vaporization) to break this bond. The hydrogen bonds holds liquid water molecules tightly to one another.
Hence, a drop of water will evaporate slower than a drop of rubbing alcohol, which has a weaker hydrogen bonding between its molecules.

Living things respond to their environment.
Living things maintain internal balance.
Living things are based on a universal genetic code.
Living things grow and develop.
1 2 3 4
5
Answer:
Living things are based on a universal genetic code.
Explanation:
DNA, also known as deoxyribonucleic acid is a nucleic acid responsible for storing genetic information in living cells. The genetic code refers to the series of nucleotides that are expressed into a protein molecule. It comprises of all the codons (group of three nucleotides) in an organism.
All living organisms are said to contain a nearly universal genetic code because the same genetic code is found in almost all living organisms. For example, AUG codon corresponds Methionine amino acid in almost all organisms.
Therefore, a blueprint of life called DNA is traceable to the fact that Living things are based on a universal genetic code.
