Answer: Zygote
Explanation:
A zygote, also called a fertilized egg, is the phase of conception where the egg and sperm join to form a single cell. The zygote contains a full set of chromosomes, with 23 from the egg and 23 from the sperm. The zygote phase lasts only about four days, after which the single cell splits rapidly to become a blastocyst and then an embryo.

Why is there such thin soil beneath such lush and dense vegetation?
Answer: In the rainforest, most of the carbon and essential nutrients are locked up in living vegetation, dead wood, and decaying leaves. As organic material decays, it is recycled so quickly that few nutrients ever reach the soil, leaving it nearly sterile

How are plants and animals(including us) dependent on each other in terms of respiration & gas exchange?explain using details of how photosynthesis and aerobic cellular respiration work together in order to maintain balance.
Animals breathe in oxygen and exhale carbon dioxide during the respiration process. In contrast, plants use this carbon dioxide gas to make food and release oxygen into the atmosphere through the process of photosynthesis.
What is photosynthesis?
Green plants and certain other organisms convert light energy into chemical energy through a process called photosynthesis. Light energy is gathered and utilized during photosynthesis in green plants to change water, carbon dioxide, and minerals into oxygen- and energy-rich organic molecules.
What is aerobic cellular respiration?
Food glucose is converted into energy during an aerobic respiration, a biological process that takes place with the presence of oxygen. the following is the chemical formula for aerobic respiration:Oxygen 6(O2) + Carbon 6(CO2) + Water 6 (H2O) + Energy = Glucose (C6H12O6) (ATP)The chemical equation above states that energy is released by breaking glucose molecules with the aid of oxygen gas. As the by-products or final products of the chemical reaction, energy, water molecules, and carbon dioxide gas are released.The breakdown of the glucose molecule releases 2900 kJ of energy, which is then used to create ATP, or adenosine triphosphate, molecules that the body uses for a variety of functions.All multicellular organisms, including animals, plants, and other living things, engage in an aerobic respiration process.The stomata, which are located in the epidermis of a plant's leaves and stem, allow oxygen gas to enter plant cells during the respiration process in plants. All green plants produce their food and release energy through the process of photosynthesis.Thus, we can conclude that animals and plants cooperate to exchange gases in the atmosphere.

hydrogen sulfide
indole and skatole
Uric acid would not be a waste product generated by the action of bacteria in the large intestine.
Uric acid is a waste product found in blood. It's created when the body breaks down chemicals called purines. Uric acid gets dissolves in the blood, passes through the kidneys and leaves the body in urine. Hence they are not waste product from the large intestine.
Kidneys excrete uric acid as a waste product. The kidneys are responsible for excreting two-thirds of the uric acid produced daily out of which one third is excreted in the stool and urine.

the most prevalent and efficient catabolic pathway for the production of atp, in which oxygen is consumed as a reactant along with the organic fuel.
The most prevalent and efficient catabolic pathway for the production of ATP, in which oxygen is consumed as a reactant along with the organic fuel is called aerobic respiration.
Catabolic pathway is a type of metabolic reaction. Here, the large-sized macromolecules are broken down into smaller particles. In aerobic respiration, glycolysis is a type of catabolic reaction in which the macromolecule glucose is broken down to yield pyruvate which is further processed to yield ATP.

why is it advantageous for cells to use atp for energy rather than simply break down any chemical bonds available?
It is advantageous for cells to use ATP for energy rather than simply break down any chemical bonds available because ATP is used by bacteria in addition to humans to provide energy and the quick energy turnover of ATP fulfills the body's fluctuating energy needs.
ATP is a highly effective molecular machine. Because of the phosphate groups connected by phosphodiester bonds, ATP makes a great "currency" molecule for energy storage. These electronegative charges that are associated with the bonds act as a repulsive force on the phosphate groups, making the bonds high-energy. A glucose molecule cannot be effectively broken down without significantly altering its structure, making it more difficult to rebuild. As a result, adding and removing those phosphate groups is much more energy efficient than adding and removing elements from a glucose molecule.

What is the difference between Paravertebral and prevertebral ganglia?
The ganglia which lie between the target organ and the sympathetic ganglia are known as prevertebral ganglia.
The ganglia which lie close to the spinal cord and the vertebrae are said to be paravertebral ganglia.
What is the function of prevertebral ganglia?
The celiac, mesenteric, and hypogastric ganglia are among the prevertebral ganglia, which also receive preganglionic axons from the splanchnic nerves and innervate the abdominal, pelvic, and perineal organs.
They are made up of postganglionic sympathetic main neurons, which supply the viscera in the abdomen and pelvis. Prevertebral ganglia contain a majority of integrating neurons that receive nervous information from preganglionic neurons in the spinal cord and intestinofugal neurons of the myenteric plexus in the gastrointestinal tract, in contrast to paravertebral ganglia, which are made up almost entirely of relay neurons receiving nervous information arising only from preganglionic neurons in the spinal cord.

The advantage of longer Henle's loop in desert animals over the shorter Henle's loop in humans is that longer loop provides greater absorption of minerals such as sodium ions, calcium ions or other ions needed for the body and restricts loss of water.
The metabolism of animals found in dry or arid regions is so designed that they can live with ease. The Henle's loop of desert animals allows greater absorption of water and thus loss of water is minimized due to the extremely concentrated urine. This limits the water needed for their survival. This allows more water to be resent back for hormonal circulation in the body.
