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.

Which statement best describes a disruption in nucleic acid sequence?
A. The nucleic acid is exposed to extreme temperature, causing denaturation.
B. New hydrogen bonds are formed, breaking the bond in the structure of the nucleic acid.
C. The lack of energy will cause the bond between the growing peptide chain to be broken.
D. The addition of an enzyme will inhibit the production of the R group in the structure.
Answer:
B. New hydrogen bonds are formed, breaking the bond in the structure of the nucleic acid.
Explanation:
Nucleic acids are one of the four major biomolecules in living systems. They function to store and transmit genetic information in living organisms. Nucleic acids are polymers made up of NUCLEOTIDE monomeric units. DNA and RNA are the two nucleic acids in nature.
However, since the complementary nucleotide bases that make up nucleic acids interact together via HYDROGEN BONDS i.e. G-C, A-U, if new hydrogen bonds are formed, breaking the bond in the structure of the nucleic acid will disrupt the nucleic acid sequence
Answer:
A. The nucleic acid is exposed to extreme temperature, causing denaturation.

How do the unique chemical properties of water affect water’s ability to occur in three states of matter?
Answer:
Water's unique properties
In the solid state, the particles of matter are usually much closer together than they are in the liquid state. So if you put a solid into its corresponding liquid, it sinks. Water's boiling point is unusually high. Other compounds similar in weight to water have a much lower boiling point.
Explanation:
The unique properties of water ( a polar molecule, it is able to form multiple hydrogen bonds, which account for many of water's special properties. ... Because of their partial positive and negative charges, polar molecules such as water can attract each other) give it it's ability to occur in the three states of matter
Water is made up of two hydrogen (H) atoms and an oxygen (O) atom. And water is unique in that it is bipolar, where the molecule has a slightly positive charge on one side (where hydrogen atoms are attached), and slightly negative on the oxygen

How does the density of liquid water compare with the
density of ice?
Answer:
The normal pattern for most compounds is that as the temperature of the liquid increases, the density decreases as the molecules spread out from each other. ... The ice structure takes up more volume than the liquid water molecules, hence ice is less dense than liquid water.
In all of our cells there is a blueprint of life called DNA. Which characteristic does this fact best describe?
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.

A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere.
Most earthquakes occur along the edge of the oceanic and continental plates. The earth's crust (the outer layer of the planet) is made up of several pieces, called plates. The plates under the oceans are called oceanic plates and the rest are continental plates.
Which are limiting nutrients for plant growth?
water and nitrogen
nitrogen and carbon
carbon and phosphorus
phosphorus and nitrogen
Answer:
phosphorus and nitrogen
Phosphorus and nitrogen are limiting nutrients for plant growth.
What are limiting nutrients for plant growth?Limiting nutrients are essential elements required for plant growth that are present in the soil in limited amounts. When the availability of these nutrients becomes insufficient, it limits plant growth and productivity. The most common limiting nutrients for plant growth are nitrogen, phosphorus, and potassium.
Nitrogen is an essential component of amino acids, proteins, and chlorophyll, and is a crucial nutrient for plant growth and development. Phosphorus plays a vital role in photosynthesis, energy transfer, and cell division. Potassium is required for enzyme activation and water regulation in plants.
Other essential nutrients like calcium, magnesium, and sulfur may also become limiting in certain soil conditions. The availability of these nutrients can be improved through fertilizer application or by incorporating organic matter into the soil. Proper management of limiting nutrients is essential for maximizing plant growth and productivity.
