Correct Answer is C
Explanation
Scientists make observations, gather data, and complete research over many years in order to compile knowledge that will provide insight into future disasters, such as earthquakes, storms, and global warming. Although science can be used to predict earthquakes and other natural disasters, there is currently no way of preventing them from occurring.
Correct Answer is D
Explanation
A solution that contains more hydroxide ions than hydrogen ions is a base, and bases have a pH greater than 7, so the only possible answer is choice D. 9.
Correct Answer is B
Explanation
The evidence says that every child in a certain family has been diagnosed with autism spectrum disorder (ASD). All of these children have genetic commonalities. Therefore, ASD may be genetic.
The evidence does not mention whether the children died from ASD. Therefore, no conclusion can be drawn that ASD may be lethal. Furthermore, the sample size of the evidence is much too small to suggest that ASD is related to traditional nuclear family structures.
Correct Answer is A
Explanation
The pituitary and the pancreas are both structures of the endocrine system that produce hormones involved in body regulation, growth reaand development, sexual functioning, and other processes. The penis Is a structure of the reproductive system that responds to hormones, but it does not produce them.

The duodenum is the first section of the small intestine. It receives partially digested food (also called chyme) from the stomach, further digesting it with the help of enzymes released by the gall bladder. Then, the food enters into the jejunum, then the ileum. The large Intestine's main function is the reabsorption of water into the body to form solid waste. It also allows for the absorption of vitamin K produced by microbes living inside the large intestine.

Explanation
Enzymes act as catalysts for biochemical reactions. A catalyst is not consumed in a reaction, but rather lowers the activation energy for that reaction. The potential energy of the substrate and the product remain the same, but the activation energy-the energy needed to make the reaction progress can be lowered with the help of an enzyme.
Correct Answer is A

Phenotype is the physical presentation of an organism's genes. In other words, the phenotype is the physical characteristics of the organism. Phenotype is often contrasted with genotype, the genetic makeup of an organism. The genotype of the organism is not visible in its presentation, although some of the characteristics encoded in the genes have to do with physical presentation. A phylum is a group of classes that are closely related. A species is a group of like organisms that are capable of breeding together and producing similar offspring.
Correct Answer is D
Explanation
Endocytosis is a process by which cells absorb larger molecules or even tiny organisms, such as bacteria, that would not be able to pass through the plasma membrane. Endocytic vesicles containing molecules from the extracellular environment often undergo further processing once they enter the cell.
Correct Answer is D
Explanation
Enzymes are substrate-specific. Most enzymes catalyze only one biochemical reaction. Their active sites are specific for a certain type of substrate and do not bind to other substrates and catalyze other reactions.
