How is the habitat of a squirrel different from its niche? The habitat is the physical space occupied by the plant or animals, while the niche is the role the plant or animal plays in the community found in the habitat. For example, the habitat of a squirrel tends to be trees, or a forest. […]

What are the four main organs of a flower? Flowers contain the plant’s reproductive structures. A typical flower has four main parts—or whorls—known as the calyx, corolla, androecium, and gynoecium (Figure 1). The outermost whorl of the flower has green, leafy structures known as sepals. What are essential floral organs Class 10? What are the […]

What is the central dogma of genetics? The ‘Central Dogma’ is the process by which the instructions in DNA are converted into a functional product. The central dogma states that the pattern of information that occurs most frequently in our cells is: From existing DNA to make new DNA (DNA replication?) From DNA to make […]

What is a potential problem with the PSC phylogenetic species concept )? What is a potential problem with the PSC (phylogenetic species concept)? It fails to recognize many monophyletic species. It leads to the recognition of a much smaller number of species than the biological species concept. It cannot be applied to organisms that reproduce […]

What is the name given to a symbiotic relationship in which both species benefit? Mutualism is a symbiotic relationship in which both species benefit. Commensalism is a symbiotic relationship in which one species benefits while the other species is not affected. Parasitism is a symbiotic relationship in which one species (the parasite) benefits while the […]

What does the inner osteogenic layer consist of? Outer fibrous layer is dense irregular connective tissue • Inner osteogenic layer, abutting the bone surface, consists primarily of bone- forming cells called osteoblasts, bone-destroying cells called osteoclasts, and primitive stem cells (osteogenic cells) that give rise to the osteoblasts. What is the function of the osteogenic […]

What happens to interphase between meiosis I and meiosis II? First thing to remember is that interphase is a stage associated with replication of DNA, and growth. Once meiosis starts, the purpose is to produce a haploid gamete. So there is no further need of replication or growth. Hence between meiosis I and meiosis II […]

Is a gene a segment of DNA? Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person’s genes. What exactly is a gene? A gene is the basic physical […]
