A fertilized egg, or zygote, is created by the union or fusing of an egg and sperm, according to the definition of fertilization.
Niacin is typically regarded as the vitamin that shields against pellagra. Niacin deficiency can cause problems with the brain system, skin, and digestive system in individuals.
The ability of at least one population to survive without the other is what defines mutualism.
An organism that is autotrophic may produce its own food, typically through photosynthesis.
The prophase is understood to be the stage of mitosis during which the chromatids in the doubled chromosomes may be seen.
The energy of the ATP, which is created in the light, is used by the dark reactions of photosynthesis to power their vital functions, all of which take place in the transparent stroma that surrounds the grana of the chloroplast.
A person with an AaBb genotype has a one in four chance of having an AB segregation of genes after meiosis.
Hydrogen to oxygen atom ratio in lipids is substantially higher than 2:1.
Folic acid is necessary for healthy bone marrow function, and a lack of it may cause several types of anemia.
When phosphorus and nitrogen-containing chemical fertilizers wash into a lake, the result is eutrophication, which raises the productivity of the photoplankton and the bottom plants. This massive growth obstructs light, killing deep-rooted plants, and certain decomposers use all the oxygen, smothering fish.
Water from a plant's aerial portion evaporates during transpiration. Diffusion is a type of molecular activity that leads to evaporation.
The functional kidney units known as nephrons reabsorb blood, sugar, amino acids, urea, different ions, and a significant amount of water while secreting vast amounts of fluid.
Conifers, especially spruces, predominate in the coniferous forest biome. Bears, mice, birds, and moose live there.
When triggered by insufficient light, stem elongation can become excessive and is known as etiolation.
Thrombin, an enzyme, transforms fibrinogen into fibrin, which progressively forms a net into which blood cells attach themselves, forming a clot.
All carbohydrates and lipids can be made from carbon, hydrogen, and oxygen, but proteins require extra elements like nitrogen and, occasionally, sulfur to be made.
