18) Which of these activities is NOT related to the digestive system?
Absorbing nutrients into the bloodstream from the small intestine
Breaking down food particles into smaller particles
Moving solid waste through the body to get rid of it
Delivering nutrients to the cells via the bloodstream
Delivering nutrients to the cells through the bloodstream is not associated with the digestive system.
How are nutrients delivered to the cells?In the process of digestion, the nutrients are absorbed into the bloodstream from the small intestine. The food particles are broken down into smaller components, and the solid waste is excreted from the body. However, the digestive system has no role in delivering nutrients to the cells.
In the body, all the cells require to have nutrients and oxygen, and they require their wastes to get discarded. All these functions are performed by the circulatory system of the body.
The blood vessels and the heart function in combination to provide the cells with the nutrients. With the assistance of the network of blood vessels, the blood collects nutrients from the food from the small intestine and delivers them to each of the cells present in the body.
Thus, the nutrients are not delivered to the cells by the digestive system, it is done by the circulatory system.

What is the purpose of mitotic cell division in multicellular organisms (give all 3 purposes)? Compare this to the purpose of mitotic cell division in single celled eukaryotes. Use vocabulary words.
Answer:
The correct answer is - The growth and tissue repair are the major purpose of mitotic cells in multicellular organisms.
Explanation:
The purpose of mitotic cell division in multicellular organisms can be understood by the three points:
1. somatic cells divide through mitotic cell division.
2. Every multicellular organism shows growth and develop with time in size
3. Every cell of the body is repaired with the help of the mitosis that replaces the damaged cell with the new cell.
Single-celled eukaryotes show asexual reproduction by binary fission which is a form of mitosis.

What role does gravity play in the water cycle?
Describe the flow of one molecule of water through the water cycle, beginning in the ocean.
PLEASE HELP 50 POINTS FOR CORRECT ANSWERS!!!!!!!!!!!!
Answer:
Increasing water salinity reduces evaporation since the dissolved salt ions lower the free energy of the water molecules, i.e., reduce the water activity, and hence reduce the saturation vapor pressure above the saline water at a given water temperature

What would most likely happen if an error occurred when RNA was receiving coding information? Proteins would be formed incorrectly. DNA would form incorrectly. RNA could not form a double helix. The incorrect amino acid would form.
Answer:
If an error occurred when RNA was receiving coding information, most likely:
Proteins would be formed incorrectly.
Explanation:
The Ribonucleic acid (RNA) is an important biological macromolecule. It is present in all biological cells which are involved in the synthesis of proteins. The RNA carries the coding instructions from the DNA and converts the information stored in DNA into proteins. Importantly, the DNA contains the genetic instructions required for the development and maintenance of all life forms.

Answer in paragraph form about mollusks.
1. Explain how biological evolution is supported by the fossil record.
2. Why is natural selection a mechanism for biological change?
3. How does chemical evolution explain the origin of life on Earth?
4. Explain why scientific theories, such as biological and chemical evolution, represent the strongest explanation of the changes observed in the fossil record.
5. How can scientific theories on evolution and the fossil record change over time?
Answer:
Molluscs have more varied forms than any other animal phylum. They include snails, slugs and other gastropods; clams and other bivalves; squids and other cephalopods; and other lesser-known but similarly distinctive subgroups. Although it is impossible to know the subjective experience of another animal with certainty, the balance of the evidence suggests that most invertebrates do not feel pain. The evidence is most robust for insects, and, for these animals, the consensus is that they do not feel pain. In general, mollusks have 3 body regions: a head, a visceral mass, and a "foot." The head contains the sense organs and "brain," while the visceral mass contains the internal organs. Mollusks usually have a shell (although some do not). Mollusks also have an extension of the body wall called the mantle.

_____________ growth occurs when the growth rate is proportional to the size of the population.
Exponential growth occurs when the growth rate is proportional to the size of the population. Therefore, the correct option is A.
What is exponential growth?Exponential growth is a pattern when the growth rate is proportional to the size of the population. In other words, as the population increases, the rate of growth also increases proportionally.
Exponential growth is a common pattern observed in populations that have abundant resources and no limiting factors. However, in real-world populations, exponential growth is not sustainable in the long term, as the population eventually reaches its carrying capacity, or the maximum number of individuals that the environment can support. At this point, the growth rate slows down and eventually stabilizes, leading to a stable population size. Therefore, the correct option is A.

A unit of hereditary information consisting of a particular nucleotide sequence in DNA is called a:
A. Polymer
B. RNA enzyme
C. Gene
D. Double helix
Answer:
C. Gene
Explanation:
Hope this will help
A unit of hereditary information consisting of a particular nucleotide sequence in DNA would be called a gene.
The basic unit of hereditary is the gene. Particularly, genes are located on chromosomes that are made of DNA. In order words, genes make up the DNA, while DNA makes up the chromosomes.
In the DNA, genes exist as genetic codes with each code specifying a particular amino acid. In order for genes to be expressed, the information on DNA are first transcribed to mRNA and the genetic codes are then translated to their respective amino acids linked together by peptide bonds.

In order for cellular respiration to effectively provide the energy your body needs to do its job, which of the following organ systems are needed?
(You may choose more than one answer.)
-Digestive system
-Respiratory system
-None of these systems support cellular respiration.
-Circulatory system
3.
The respiratory system supports the skeletal muscular system by:
-he respiratory system does not support the skeletal muscular system.
-transporting oxygen needed to release energy from glucose to the body's cells.
-breaking down the glucose to release energy.
-digesting the glucose you eat.
Answer:
1A - Respiratory = trachea, lungs... however both arteries and veins move oxygen around the body, and are therefore valid answers
1B - Skeletal = bones
1C - Muscular = muscles
1D - Digestive = stomach, large/small intestine
1E - Circulatory = heart, veins and arteries
2. Cellular respiration is the conversion of sugar into energy the cell uses to function via various chemical reactions. Digestion is an example of this. Stomach acid breaks down food into sugars that cells break down further into energy to keep you alive
3. Bones contain bone marrow deep inside of them which is responsible for the creation of red blood cells. Your lungs can move air all they want but would be useless without red blood cells to take the oxygen to cells and take the CO2 away from them.
