The most important element in living organisms is carbon and is found in all the four biomolecules; lipids, carbohydrates, proteins, and nucleic acids.
What is the role of carbon in living organisms?Carbon is the most important element in living organisms.
Carbon is an element that is considered as the foundation of life. From this element comes 4 types of biomolecules. They are lipids, carbohydrates, proteins, and nucleic acids.
These biomolecules have building blocks that we call as monomers . Like a Lego, it acts like Lego the blocks to form each molecule. Carbohydrates monomer is called monosaccharides. The Lipids monomer is composed of two. They are fatty acids and glycerol. Proteins also have monomer. It is called amino acids.
Our DNA is composed of chains of nucleic acids which also have nucleotides as its monomer. All biomolecules contain these 3 atoms or elements. They are carbon, hydrogen, and oxygen.
In conclusion, the four biomolecules lipids, carbohydrates, proteins, and nucleic acids are all composed of carbon, hydrogen and oxygen.

Answers
The core cell body, where the signal is being conveyed, is the answer.
The nucleus, associated cytoplasm, organelles, and other cell constituents make up the central cell body, or process part, of a neuron. Other parts of the neuron are constructed using proteins produced in the cell body. The presynaptic (or sending) neuron releases a neurotransmitter, which then attaches to a receptor on the surface of the postsynaptic (or receiving) neuron. Neurotransmitters are released by presynaptic terminals, which may branch to connect with a number of postsynaptic neurons. An action potential is the consequence of a neuron's reaction to threshold or suprathreshold stimuli. Its three phases are depolarization, overshoot, and repolarization.

What is the actual "signal" that is being transduced in any signal transduction pathway, such as those shown in Figures 11.6 and 11.10 ? In what way is this information being passed from the exterior to the interior of the cell?
Answers
The signal being transmitted is the knowledge that a signaling molecule is bound to a cell-surface receptor. Sequential protein-protein interactions change protein shapes, causing them to function in a way that allows the signal (the information) to pass through.
The binding of extracellular signaling molecules and ligands to receptors on the cell surface or within the cell that trigger events inside the cell to elicit a response is referred to as the signal transduction pathway. The response can then change the metabolism, form, and gene expression of the cell.

MAKE CONNECTIONS Focusing just on the effects of temperature, would you expect the global distribution of C₄ plants to expand or contract as Earth becomes warmer? Why? (See Concept 10.4.)
Answers
A benefit of C₄ photosynthesis is that it reduces photorespiration and increases sugar production, which is particularly helpful in warmer climates where C₄ plants are currently found.
As the climate on Earth warms, it is expected that plants that use C₄ photosynthesis will spread out globally. A C₄ plant starts the Calvin-Benson cycle of photosynthesis by fixing CO₂ into a molecule with four carbon atoms. The Hatch-Slack route is another name for the C₄ pathway. It is one of the three photosynthetic routes that have been identified for carbon fixation in plants. The term derives from the 1960s discovery of the C₄ cycle by Marshall Davidson Hatch and Charles Roger Slack. This suggests that some plants initially aggregate the 14C label into four-carbon molecules when given 14CO₂.Learn more about the C₄ Plants with the help of the given link:

Suppose you were given a chemical compound that could enter the egg and bind to Ca²⁺, blocking its function. How would you use this compound to further test the hypothesis that a rise in Ca²⁺ level triggers cortical granule fusion?
Answers
Due to the compound blocking the Ca2+ functions, their will be a delay in cortical granule fusion with the egg plasma membrane. This will test the hypothesis that a rise in Ca²⁺ level triggers cortical granule fusion.
The cortex of unfertilized oocytes contains membrane-bound organelles called cortical granules. Cortical granules go through exocytosis after fertilization to release their contents into the perivitelline region. The cortical response is the name given to this secretory mechanism, which depends on calcium and uses a SNARE protein-mediated pathway. The cortical granule proteins that are released after exocytosis alter the extracellular matrix of the oocytes, such as the zona pellucida in mammals, to prevent polyspermy. Mammalian cortical granules, which differ from most other regulating secretory organelles in that they are not replenished once released, range in size from 0.2 um to 0.6 um in diameter. Only female germ cells may produce these granules, which change an egg upon sperm entrance.Therefore, a delay will be observed in the cortical plasma membrane fusion.

Why does deforestation of a watershed increase the concentration of nitrates in streams draining the watershed?
Answers
Deforestation stops nitrogen uptake from the soil, allowing nitrate to accumulate there. The nitrate is washed away via precipitation and enters the streams.
Deforestation shows that also beneath herbal conditions, nitrogen fixation may be followed through nitrification with subsequent leaching of nitrate into the groundwater. but, anthropogenic activities, which include deforestation, can alter the N-cycle by means of producing immoderate mobile nitrate.
Nitrate and nitrite concentrations additionally extensively boom in deforested watersheds. at the same time as nitrogen concentrations in water frequently increase with nitrogen deposition and fertilization, the villages surrounding the streams studied do no longer have big assets of nitrogen additions to the atmosphere.
