Prokaryotes can carry out a variety of activities in response to certain chemical signals. Here are some examples: Chemotaxis: This is the movement of an organism in response to a chemical gradient. For example, bacteria can move towards food sources or away from harmful substances. Quorum sensing: This is a process by which bacteria communicate … Read more
Translation can take place in several different places, depending on the context. In biology, translation is the process of converting the genetic code in DNA into a sequence of amino acids that make up a protein. This process takes place inside ribosomes, which are small organelles found in the cytoplasm of cells. In linguistics, translation … Read more
Biodiversity loss is the decline or disappearance of biological diversity, understood as the variety of living things that inhabit the planet, its different levels of biological organization and their respective genetic variability, as well as the natural patterns present in ecosystems. It can be caused by a variety of factors, including: Habitat destruction: This is … Read more
Which trophic level has the least available energy in kilojoules in this food web? The trophic level with the least available energy in kilojoules in the given food web is the top predator. This is because energy is lost at each trophic level due to respiration, heat loss, and incomplete digestion. As a result, the … Read more
The following differences between Bryophytes and Pteridophytes are given below: No. Bryophytes Pteridophytes 1 The plant body cannot be divided into root, stem, and leaves. The plant body is divided into root, stem, and leaves. 2 The thallus is game tophytic. The thallus is sporophytic. 3 Vascular tissue is absent. Vascular tissue is present. 4 … Read more
Why is the plasma membrane semiliquid in nature? Explain. The plasma membrane is semi-liquid in nature because the interior of the phospholipid bilayer is occupied by hydrophobic fatty acid chains, the membrane is impermeable to water-soluble molecules, including ions and most biological molecules. Besides, bilayers of the naturally occurring phospholipids are viscous fluids, not solids. … Read more
What do you mean by fruit body? In fungi, the fruit body is a multicellular structure on which spore-producing structures, such as basidia or asci, are developed. The fruit body is part of the sexual phase of a fungal life cycle, while the rest of the life cycle is characterized by vegetative mycelial growth and … Read more
What do you mean by the transport system of cells? Transport is the collection of mechanisms that regulate the passage of solutes such as ions and small molecules through biological membranes, which are lipid bilayers that contain proteins embedded in them. A transport system is a means by which materials are moved (transported) from an … Read more
