B. Gametophytes produce diploid gamers (the gametes are haploid)
The correct answer is C. The temperature of the water
Explanation:
In an experiment such as the one described about the speed of snails in water, the manipulated variable is the factor or element that is manipulated on purpose. This means the researcher or researchers slightly change this element to compare how this affects another variable. In this context, the manipulated variable is the temperature of the water because researchers used three different temperatures (cool, room-temperature, and warm), and therefore they manipulated or changed this factor. Moreover, it is expected temperature affects the distance nails move, which is the main variable.
Answer:
Cristal is formed when the solution is cooling because the solvent can't keep all the molecules of the substance and these molecules are beginning to leave the solvent and form solid crystals.
Explanation:
It means that every crystal is formed of one molecule of the solvent. When the solvent reaches room temperature, it is moved to the ice bath to finish the process of crystallization.
Data tables help us understand information by comparing and contrasting it with visual proof. Sorry, that's all I could come up with.
Mycorrhizae, specialized symbiotic associations between the roots of plants and fungi, are characteristic of about 90% of all plants.
Mycorrhizal fungi are a symbiotic combination of fungi and plants. The term mycorrhiza refers to the role of fungi in a plant's rhizome, its root system. Mycorrhizae play an important role in plant nutrition, soil biology, and soil chemistry.
In mycorrhizal organization, the fungus resides in the root tissues of the host plant, either intracellularly as in arbuscular mycorrhizal fungi (AMF or AM), or extracellularly as in extrinsic fungi.
The association is sometimes reciprocal. In some species or in specific cases, mycorrhizal fungi may have a parasitic association with the host plant.
Mycorrhizae are generally divided into ectomycorrhizae and endomycorrhizae. These two types are distinguished by the fact that mycelium of mycorrhizal fungi does not penetrate individual root cells while mycelium of endophytic fungi penetrates the cell wall and penetrates the cell membrane.
