Answer:
The population sizes of organisms that benefit from such an interaction are likely to increase. Likewise, if an interaction is disadvantageous for an organism, then that organism's population size is likely to decrease. Predation occurs when a predator hunts for another organism.
False. Streams lose velocity when the slope of the stream bed decreases.
DNA is organized into chromosomes. The organisms genome is the DNA in all their chromosomes.
During meiosis, the process that creates eggs and sperms, homologous chromosomes line up and recombine, meaning their sequences get mixed up together to form new chromosomes. One of each of these new chromosomes is independently assorted into daughter cells, so that each egg and sperm contain only one chromosome necessary (1n). When the sperm combines with the egg, the zygote (new organism) contains a copy of a homologous chromosome from each parent (2n).
Ans: D
Chemical changes:-
occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.
