What types of reaction is Cu (s) + 2AgNO3(aq) → 2Ag(s) + Cu(NO3)2(aq)?

A. They change shape when they bind their substrates.

B. They can catalyze reactions in both forward and reverse directions.

C. Their activity is sensitive to changes in temperature.

D. They are always active on more than one kind of substrate.

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.

A. Breakage

B. Deletion

C. Insertion

D. Inversion

An inversion mutation is represented in the sequence 1 5 4 3 2 6. An inversion error is a type of mutation where an entire sequence of DNA is reversed. In this case, 2 3 4 5 has been reversed to 5 4 3 2.

Breakage, choice A, in a gene can mess up its function entirely or lead to a translocation of genetic information. Choice B, deletion, is when a section of DNA is omitted or lost.

Choice C, Insertion, is when an extra base pair is added to a DNA sequence. Deletions and insertions can lead to a frameshift effect where entire sequences are thrown off because one nucleotide is wrong.

This could result in coding for the wrong amino acid and non-functioning proteins.

A. They are involved in the secretion of glucose.

B. They are responsible for storing the fat that is found in adipose tissue

C. They are critical in the digestive breakdown of fat

D. They are the foundational element of muscles

Adipocytes are primarily seen in adipose or fat tissue. Their primary function is the storage of fat Adipocytes play a crucial role in maintaining proper energy balance, storing calories in the form of lipids, and mobilizing energy sources in response to stress. They are not involved in the digestion of fat or the secretion of glucose, nor are they the foundational element of muscles

A. Two genes next to each other on a chromosome

B. Two genes on opposite ends of a chromosome

C. Flower color and height in snapdragons

D. Seed color and flower color in peas

Two genes next to each other (or within a specified close distance) are said to be linked. Linked genes do not follow the law of Independent assortment because they are too close together to be segregated from each other in meiosis.

A. Centimeters

B. Meters

C. Micrometers

D. Kilometers

The best use of the International System of Units (SI) for this situation would be the use of the micrometer as it is the smallest unit of measurement provided and the scientist is using a microscope to view the insects.

A. Phenotype

B. Species

C. Phylum

D. Genotype

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.

A. Plants need more than 200 mL of liquid per week.

B. Salt has no impact on plant health.

C. Salt contains useful nutrients for plants.

D. A combination of the solutions tested will produce healthier plants.

Since only 2 out of the initial 16 plants survived the whole month, it would be reasonable to test variables that were shared by all the plants. As such, the amount of liquid the plants need would be a good follow-up experiment. It is not specified as to which plants survived, so there is not enough information to think that testing the impact of salt is warranted. Additionally, since almost all the plants died, it is not reasonable to assume that a combination of the solutions would have an impact.

A. Releasing compressed gas to make a bottle-rocket launch

B. Adding water to clay to make slip

C. Crystalizing honey to make candy

D. Including baking soda in a recipe to make it less sour

A chemical change involves a chemical reaction and new substances are produced. When baking soda is added to something sour (acidic) it neutralizes the acid and forms new molecules, in this case carbon dioxide and water. A physical change does not produce new substances. Phase changes such as evaporation and sublimation are physical changes. Changing the ratio of ingredients in a mixture, like adding more water to clay, does not change it chemically, but it can change some of the mixture's physical properties.

A. A better understanding of the physical world

B. The ability to predict possible outcomes affected by actions

C. The ability to prevent earthquakes and other natural disasters

D. The creation of various substances and technologies that enhance our world

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.

A. Negative feedback

B. Positive feedback

C. Stress response

D. Parasympathetic regulation

Maintaining homeostasis means that conditions are kept stable and relatively constant. Negative feedback is a mechanism used to reverse or minimize changes in a system. In this example, negative feedback is used to keep the body's glucose and insulin levels stable. Positive feedback (B) is a mechanism that Increases changes in a system. A stress response (C) describes the body's reaction to threats or pressures. Parasympathetic regulation (D) refers to activities of the nervous system, including slowing the heart rate and boosting Intestinal activity.
