i think it is because diffusion that water gets into the cells of few organisms. The specific type of transport used is osmosis. Diffusion is the net movement of substances typically from a rgion of high concentration to low concentration. This process does not require energy. Osmosis is diffusion but is specific to water.

Is this a statement or a question? I have no idea what you are asking. Are you needing the the names of these pathways, enzymes, or substrates? Pathways: Animals * Glycolysis * Kreb's Cycle * Electron Transport Chain * Oxidative Phosphorylation (ATP Synthase) Plants * Calvin Cycle Enzymes: * Too many to name or be more specific Substrates: * Also too many to name unless you are talking about a specific pathway If you are asking which enzymes occur in both aerobic respiration and photosynthesis: * Glyceraldehyde 3-phosphate dehydrogenase * Phosphoglycerate kinase * Triosephosphate isomerase (TIM) * Aldolase

Lactase enzyme is present in infants but can decrease in activity as they grow into adulthood, leading to lactose intolerance in some individuals.

• The small subunit of the ribosome binds to a site "upstream" (on the 5' side) of the start of the message.
• It proceeds downstream (5' -> 3') until it encounters the start codon AUG. (The region between the mRNA cap and the AUG is known as the 5'-untranslated region [5'-UTR].)
• Here it is joined by the large subunit and a special initiator tRNA.
• The initiator tRNA binds to the P site (shown in pink) on the ribosome.
• In eukaryotes, initiator tRNA carries methionine (Met). (Bacteria use a modified methionine designated fMet.)

The two transport systems in a tree are the xylem and phloem. The xylem transports water and minerals from the roots to the rest of the plant, while the phloem transports sugars produced through photosynthesis to other parts of the tree.

The basic building blocks of organic compounds are carbon, hydrogen, oxygen, nitrogen, and a few other elements like sulfur and phosphorus. These elements combine in various ways to form the diverse range of organic molecules found in living organisms. Carbon is especially important because of its ability to form long chains and complex structures.

They are called fats {not quite the same as a fatty acid} - and they are from animal origins. They are saturated - in space they are straight like a tooth pick [and they stack pretty much like a box of tooth picks]. When C=C double bonds are included, the Lipid becomes unsaturated which gives the lipid a 'dogs leg' bend - called Oils, they do not then conform into a solid as easily as they did when they were saturated {and are liquid at room temperature}.

The water's temperature is the number one factor that determines the types of organisms that can live in a body of water. Organisms are adapted to specific temperature ranges, so water temperature directly influences the diversity and distribution of aquatic life.

To determine the number of amino acids in your protein, you can use the average molecular weight of an amino acid which is about 110 Da (Daltons). By dividing the molecular weight of your protein (8.9 kD or 8900 Da) by the average weight of an amino acid (110 Da), you can estimate that your protein contains approximately 81 amino acids.

Hormone levels are regulated through a feedback system involving the endocrine glands. When the body detects a need for a particular hormone, such as in response to stress or low blood sugar, signals are sent to the endocrine glands to release the hormone. Once the hormone reaches the desired level, signals are sent to stop its production, maintaining balance in the body.

During Glycolysis, ATP is used as an intermediate. ATP is cleaved and turned into ADP during the first part of glycolysis, giving one of its phosphate groups to glucose. In the ending steps of glycolysis, ATP is produced by substrate-level phosphorylation.

There are 3 nitrogen bases equalling one amino acid and they are called codons. Amino acids are the building blocks of protein and in turn protein in science is one of the building blocks of life. The protein molecule has the chromosome strands. On each strand of the chromosome there are shapes in groups of 3 which is the RNA or the Ribonucleic Acid. Where the chromosomes are located, the strands have messengers that travel outside to the ribosomes to be decoded or decyphered. Once the RNA has been decoded by the ribosomes the amino acid is formed. The chronological order of the amino acid being decyphered determines the type of protein. Protein is essential for human growth as it helps with the repair of our muscles amoungst many of it's uses.

The catabolic pathway is a series of chemical reactions through which foodstuffs are oxidized to yield energy in the form of ATP; they common catabolic pathway consists of (1) the citric acid cycle, and (2) oxidative phophorylation.

The cell membrane, which is a structure surrounding the cell, controls the passage of nutrients, water, and oxygen in and out of the cell. It acts as a selective barrier, allowing specific molecules to pass through via processes like diffusion or active transport.

Currently, there is no known way to alter the molecular structure of a human to make them completely resistant to gamma rays and other radiation. Existing protective gear such as lead shielding can help reduce exposure, but complete immunity to radiation is not achievable at this time. Outer space exploration involves various risks, including radiation exposure, which must be managed with careful planning and precautionary measures.

Sex cells, or germ cells; in females the eggs, and in males the sperm. They go through meiosis, and unlike in mitosis are only haploid, so they only have one copy of the genetic material, so that when they meet with another germ cell, they form a diploid zygote.

The Calvin cycle is a series of reaction that regenerates its starting material after molecules enter and leave the cycle. It builds carbohydrates (specifically, the sugar glyceraldehyde-3-phosphate) from smaller molecules and consumes energy. To do this, the Calvin cycle uses ATP as an energy source and consumes NADPH as reducing power.

The essential molecules of DNA are nucleotides, which are made up of a sugar molecule (deoxyribose), a phosphate group, and a nitrogenous base (adenine, thymine, cytosine, or guanine). These nucleotides are arranged in a specific sequence to form the double helix structure of DNA, which carries genetic information in living organisms.

The nitrogen cycle helps plants by establishing a symbiotic relationship with nitrogen-fixing bacteria living in nodules on plant roots. These bacteria convert atmospheric nitrogen into a form that plants can use for growth, supporting plant health and productivity.

Color can be used for comparing similar solutions because it can highlight differences between similar data points effectively. However, using color to compare different solutions may lead to confusion as it can create false associations or imply relationships that do not exist, especially if the solutions are unrelated. It is better to use other visual elements such as labels or shapes to compare different solutions accurately.
