Answer the following question given this paragraph: The process by which an organism develops from a single-celled zygote to a multi-cellular organism is complex and well regulated. The regulation occurs through signaling between cells and tissues and responses in the form of differential gene expression. Q: The process by which an organism develops from a single-celled zygote to a multi-cellular organism is complex and well regulated. the regulation occurs through signaling between cells and tissues and responses in the form of what? Choices: - phenotype exchange - spontaneous mutation - dna replication - differential gene expression A:
differential gene expression
Answer the following question given this paragraph: Q: The number of possible isomers increases tremendously as carbon skeletons increase in what? Choices: - variation - mass - weight - size A:
size
Q: Answer the following question given this paragraph: Flowers and Fruits as an Evolutionary Adaptation Angiosperms produce their gametes in separate organs, which are usually housed in a flower. Both fertilization and embryo development take place inside an anatomical structure that provides a stable system of sexual reproduction largely sheltered from environmental fluctuations. Flowering plants are the most diverse phylum on Earth after insects; flowers come in a bewildering array of sizes, shapes, colors, smells, and arrangements. Most flowers have a mutualistic pollinator, with the distinctive features of flowers reflecting the nature of the pollination agent. The relationship between pollinator and flower characteristics is one of the great examples of coevolution. Following fertilization of the egg, the ovule grows into a seed. The surrounding tissues of the ovary thicken, developing into a fruit that will protect the seed and often ensure its dispersal over a wide geographic range. Not all fruits develop from an ovary; such structures are "false fruits. " Like flowers, fruit can vary tremendously in appearance, size, smell, and taste. Tomatoes, walnut shells and avocados are all examples of fruit. As with pollen and seeds, fruits also act as agents of dispersal. Some may be carried away by the wind. Many attract animals that will eat the fruit and pass the seeds through their digestive systems, then deposit the seeds in another location. Cockleburs are covered with stiff, hooked spines that can hook into fur (or clothing) and hitch a ride on an animal for long distances. The cockleburs that clung to the velvet trousers of an enterprising Swiss hiker, George de Mestral, inspired his invention of the loop and hook fastener he named Velcro. Q: Angiosperms produce their gametes in separate organs, which are usually housed in these? Choices: - leaves - stems - seeds - flowers A:
A: flowers

Answer the following question given this paragraph: For example, remember that for the height gene in pea plants there are two possible factors. These factors are alleles. There is a dominant allele for tallness (T) and a recessive allele for shortness (t) . Q: What factors determine the effect of a gene? Choices: - metabolites - genomes - ribosomes - alleles A:
**Answer**
alleles
Answer the following question given this paragraph: 7. Like the Richter scale, the moment magnitude scale is logarithmic. The 2011 Tohoku earthquake in Japan was 9.0 and did tremendous damage. A few months earlier, an 8.8 struck Chile and did much less damage. Why?. Q: What type of scale is the richter scale? Choices: - dimensional - algorithmic - asymmetric - logarithmic A:
logarithmic
