Which of the following are formed when the plasma membrane surrounds a particle outside of the cell?
Golgi bodies
Rough endoplasmic reticulum
Secretory vesicles
Endocytic vesicles
Correct Answer : D
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 A
Explanation
This is a single replacement reaction in which copper replaces silver. The copper combines with the nitrate ions, and the silver precipitates out. Single replacement reactions have the general form of
A + BC →AC + B. Double replacement reactions have the general form of AB + CD→
 AD + CB. Synthesis reactions have the general form of A + B →
AB. Decomposition reactions have the general form AB→
 A+B.
Correct Answer is D
Explanation
A hypothesis is the use of prior knowledge in order to provide a hypothetical explanation for why something may or may not occur. A hypothesis can be proved wrong or right based on the results of the experiment and repeated trials.
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
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.
Correct Answer is D
Explanation
The scapula, commonly known as the shoulder blade, is above the olecranon, commonly known as the elbow. Conversely, the olecranon is distal or inferior to the scapula.
Correct Answer is B
Explanation
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
Correct Answer is D
Explanation
Homeostatic mechanisms are involuntary actions by organs, glands, tissues and cells to maintain balance within the body. If a function is disrupted the body will readjust in an attempt to maintain balance. During periods of starvation the body will break down glucose reserves in order to maintain normal glucose levels.
Correct Answer is C
Explanation
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.
Correct Answer is D
Explanation
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.
Correct Answer is C
Explanation
In general, atomic radius increases moving down a group due to the increasing number of electron shells. In general, atomic radius decreases moving from left to right across a period due to the increasing number of protons in the energy level. Therefore, atoms of elements in the bottom-left corner of the periodic table tend to have the largest atomic radii.
