Q: Answer the following question given this paragraph: When it comes to energy, ecosystems are not closed. They need constant inputs of energy. Most ecosystems get energy from sunlight. A small minority get energy from chemical compounds. Unlike energy, matter is not constantly added to ecosystems. Instead, it is recycled. Water and elements such as carbon and nitrogen are used over and over again. Q: What do most ecosystems get energy from? Choices: - magma - moisture - evaporation - sunlight A:
A: sunlight
Question: 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:
Answer: differential gene expression

Answer the following question given this paragraph: After Mendel's first set of experiments, Mendel wanted to see if the inheritance of characteristics were dependent, or were they independent events. Mendel asked if the segregation of the heritable factors (allele) for one characteristic (gene) had any effect of the segregation of the factors for another characteristic. For example, did the segregation of the flower color factors have any effect on the segregation of the seed shape factors? So Mendel performed crosses in which he followed the segregation of two genes. Mendel crossed pea plants that differed in two characteristics, such as seed color and shape. A dihybrid cross is a cross in which the inheritance of two characteristics are tracked at the same time. The offspring of such a cross are called dihybrids . Q: What is the term for a cross in which the inheritance of two characteristics are tracked at the same time? Choices: - fraternal - identical twin - Mendelian - dihybrid cross A:
**Answer**
dihybrid cross
