Explain why it's advantageous to have several different organ systems instead of one large system to handle all of the human body's functions.
Answers
Answer:
to avoid a general collapse of the system (eventually caused by the failure of the local organs)
Explanation:
An organ system can be defined as a group of organs that work together as a unit in order to perform a particular function. In an organ system, each organ has specific functions and is composed of different tissues that in turn have specialized tasks. Organ systems include, among others, the cardiovascular system, respiratory system, digestive system, urinary system, skeletal system, endocrine system, nervous system, etc.
which of the following statements would be the most INCORRECT if there were a sudden decline in plants on earth?
Answers
You did not put any choices.
The statement that is most incorrect if there were a sudden decline in plants on earth is the rate of photosynthesis in existing plants would decline. The correct option is b.
What is the importance of plants on earth?Plants are autotrophs, and they produce food for themselves and other consumers like animals and humans. As plants consume carbon dioxide, they reduce the warmth of the earth and thus maintain the temperature of the earth.
Photosynthesis, the method used by plants and other autotrophic organisms to make food, converts carbon dioxide into glucose and oxygen, both of which are vital for life.
The number of plants would not decrease the rate of photosynthesis, as more carbon dioxide will increase photosynthesis.
Therefore, the correct option is b, The rate of photosynthesis in existing plants would decline.

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.
Answers
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.

What would be a good "control" setup if you were testing whether spontaneous generation can occur in a piece of bread?
Answers
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 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.
Answers
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.

How do the unique chemical properties of water affect water’s ability to occur in three states of matter?
Answers
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

Which are limiting nutrients for plant growth?
water and nitrogen
nitrogen and carbon
carbon and phosphorus
phosphorus and nitrogen
Answers
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.
