Which of the following molecules exhibits ionic bonding?

A. 1s

B. 3s

C. 4p

D. 6s

Of these orbitals, the last to fill is 6s.

Orbitals fill in the following order: 1s, 25, 2p. 35, 3p, 4s, 3d, 4p, 55, 4d, 5p. 6s, 4f, 5d, 6p. 7s, 5f, 6d, and 7p. The number is the orbital number, and the letter is the sublevel identification. Sublevels has one orbital and can hold a maximum of two electrons. Sublevel p has three orbitals and can hold a maximum of six electrons. Sublevel d has five orbitals and can hold a maximum of 10 electrons, Sublevel f has seven orbitals and can hold a maximum of 14 electrons.

A. Fibrous

B. Membrane

C. Globular

D. Unsaturated

There are three types of proteins: fibrous, membrane, and globular. Fibrous or structural proteins consist of collagen, elastin, and keratin. Membrane proteins are interactive and anchored to a membrane. Globular proteins consist of functional proteins like enzymes, hemoglobin, and insulin.

Therefore unsaturated is the correct answer.

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. CH4 + 2O2 = 2CO2 + 2H2O

B. 2CH4 + 4O2 = 2CO2 + H2O

C. 2CH4 + O2 = 2CO2 + H2O

D. CH4 + 2O2 = CO2 + 2H2O

For the formula CH4 + 2O2 = CO2 + H2O to be balanced there must be an equal number of molecules on both the reactant and product sides. In this case, for the formula to be balanced, a coefficient of a 2 needs to be placed in front of the O2 and the H2O molecules. This would make both the reactant and product sides have one carbon, four hydrogens, and four oxygens

A. Correlation can show the relationship between variables.

B. Correlation can show cause and effect.

C. Correlation can show linear relationships.

D. Correlation can show nonlinear relationships.

Correlations may be positive or negative and linear or nonlinear. However, correlation does not determine cause and effect. Correlation does not necessarily mean causation.

A. Medial collateral ligament

B. Patella

C. Lateral malleolus

D. Lateral meniscus

The term "lateral malleolus" refers to the bony prominence on the outer side of the ankle.

It is part of the ankle joint, not the knee joint. The other options, such as the medial collateral ligament, patella, and lateral meniscus, are all associated with the knee joint.

A. Cell body

B. Axon

C. Neuron

D. Myelin

Axons carry action potential in the direction of synapses. Axons are the long, fiber-like structures that carry information from neurons. Electrical impulses travel along the body of the axons, some of which are up to a foot long.

A neuron is a type of cell that is responsible for sending information throughout the body. There are several types of neurons, including muscle neurons, which respond to instructions for movement; sensory neurons, which transmit information about the external world; and interneurons, which relay messages between neurons. Myelin is a fat that coats the nerves and ensures the accurate transmission of information in the nervous system.

A. Cellulose

B. Hemoglobin

C. Estrogen

D. ATP

Cellulose is a complex carbohydrate that composes the better part of the cell wall.

Hemoglobin is a protein and is found in red blood cells. Adenosine triphosphate (ATP) is a compound used by living organisms to store and use energy. Estrogen is a steroid hormone that stimulates the development of female sex characteristics.

A. Dally screen usage in the United States decreases with age

B. Daily screen usage in the United States, increases with age.

C. In the United States, most people use screens more than 3 but less than13 hours a day

D. In the United States, people over 75 generally don't use screens.

The percentage of respondents that indicated average screen usage between 4-12 hours per day is (628 +650+389) ÷ 2, 307 ≈ 0.723 or 72.3% This is indeed a significant majority of the responses and would be a reasonable conclusion. The highest screen usage is in the middle two groups with both the younger and older groups indicating less screen usage, so the daily usage neither increases nor decreases with age. While the oldest group shows the least usage per day, the survey data indicates that some of the Individuals over 75 do indeed use screens.

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.
