An igneous rock that has silica and the ferromagnesian matter has basaltic composition. It contains silicate dark materials caused by iron and magnesium. The elements such as <span>olivine, pyroxene, amphibole, and biotite are also present on this igneous rock. On the other hand, light colored have a different composition.</span>
Answer:
Explanation:
The spores of some fungi are dispersed in water or on the surface of water. The chemical composition of the wall of these spores makes them "non-wettable" so they won't sink. The spores are carried along on the surface of the water like little boats. Water in the form of raindrops can disperse spores in a different way. While gravity is not a primary means of spore dispersal, evolutionary adaptations have been required of many fungi to overcome gravitational effects for effective spore dispersal. SPORE DISPERSAL BY WIND Dispersal of fungal spores by wind is by far the most common method for terrestrial fungi.
Answer:
If the string of beads refer to a chromosome, then each bead is a gene responsible for one or more traits.
If the string of beads refer to a gene, then each bead refers to the sequence of nitrogenous bases in one strand of the gene.
Explanation:
A chromosome is composed of several genes.
A gene is composed of several nucleotides each containing a nitrogenous base. A gene is primarily made functional by the sequence of nitrogenous bases in its structure. If AGATTCA is a hypothetical sequence of the nitrogenous bases on one strand of a hypothetical gene then TCTAAGT will be the sequence of nitrogenous bases on the complementary strand of that particular gene.
