Supersaturation is a not a naturally occurring lipid.
Prophase is the first and longest stage of mitosis. In this stage, the chromosomes become visible and the centrioles separate and move to opposite poles of the cell. Metaphase is the second stage of mitosis. In this stage, the chromosomes line up across the center of the cell and become connected to the spindle fiber at their centromere. Anaphase is the third stage of mitosis. In this stage, the sister chromatids separate into individual chromosomes and are pulled apart. Telophase is the fourth and last stage of mitosis. During this stage, the chromosomes gather at opposite ends of the cell and lose their distinct rod-like shapes. Two new nuclear membranes then form around each of the two regions of DNA and the spindle fibers disappear. Qs What is the role of the Golgi apparatus in the cell? A. To uptake food through the cell membrane B. To produce cellular respiration C. To provide intracellular digestion D. To provide transportation of materials throughout the cell - n Ans✔ : To provide transportation of materials throughout the cell
The Golgi apparatus is responsible for the transportation of materials throughout the cell. The Golgi apparatus, also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells. Intracellular digestion occurs within lysosomes. Uptaking food is the job of vacuoles. Cellular respiration is the function of mitochondria. Qs When hydrocarbon is heated, its products are carbon dioxide and water. This is an example of which of the following? A. Decomposition B. Combustion C. Single replacement D. Synthesis - n Ans✔ : Combustion An example of combustion is when hydrocarbon is heated and its products are carbon dioxide and water. Combustion is an exothermic chemical reaction that occurs when heat acts on oxygen or a fuel compound.
are shared and when two neutrons bond are incorrect because covalent bonds are formed when electrons are shared. Qs Which suffix should be added to a word function to indicate resembling? A. -ess B. -oid C. -fy D. -ive - n Ans✔ : -oid The suffix -oid is added to a word function to indicate resembling. For example, tabloid means resembling a newspaper, and spheroid means resembling a sphere. The suffix -ive is added to a word function to indicate causing or making. The suffix -ess is added to a word function to indicate female. The suffix -fy is added to a word function to indicate make. Qs
Atoms are made up of all except which of the following? A. Electrons B. Isotopes C. Protons D. Neutrons - n Ans✔ : Isotopes Isotopes are atoms that have an equal number of protons but a different number of neutrons. Thus, atoms are made up of protons, neutrons, and electrons. The diagram further illustrates the composition of the atom. Qs To which body system does cartilage belong? A. Neuromuscular system B.
Plasma - n Ans✔ : Solid Solid is the phase of matter in which molecules exert a strong attraction to one another as they move slowly relative to one another. Plasma is the phase of matter that is made up of electrons and positive ions. Liquid is the phase of matter in which molecules exert moderate attractions to one another as they move at moderate speeds. Gas is the phase of matter in which molecules exert little or no attraction to one another because they move at high speeds. Qs Adrenocorticotropic hormone (ACTH) is produced by the pituitary gland. Which of the following identifies a function of adrenocorticotropic hormone? A. Cortisol production B. Testosterone regulation C. Water balance regulation D.
Milk production stimulation - n Ans✔ Correct answer: Cortisol production The endocrine system is a set of organs that secrete hormones directly into the circulatory system. Its principle functions are hormone production and internal communication and coordination. The major glands in the endocrine system are the pineal, hypothalamus, pituitary, thyroid and parathyroid, thymus, adrenal, pancreas, and ovaries or testes. These glands send hormones through the blood to other organs and tissues in the body to control the function of that organ. Cortisol production is a function of the adrenocorticotropic hormone (ACTH). Cortisol helps reduce stress and maintain one's blood pressure. Milk production stimulation is a function of the prolactin hormone. Testosterone regulation is a function of the luteinizing hormone. Water balance regulation is a function of the antidiuretic hormone. Qs Which of the following is the metric system's basic measure of weight? A. Ounce B. Gram C. Ton
Ans✔ Correct answer: He He ran over the bike with a yellow truck. A pronoun is a word that takes the place of a noun. In this case, the word he replaces the name of the person who ran over the bike. In this sentence, bike is a noun, yellow is an adjective, and over is a preposition. Qs Read the following sentence, and select the meaning of the italicized word. Insulin is endogenous and helps regulate blood sugar levels. A. Located within the body B. Produced within the body C. Produced outside the body D. Located outside the body - n Ans✔
Correct answer: Produced within the body The term "endogenous" means produced within the body. Insulin is produced within the body and helps regulate blood sugar levels. The term "exogenous" means produced outside the body. The term "external" means located outside the body. The term "internal" means located within the body. Qs The author will typically use transition words such as one, next, another, first, and finally when writing what type of sentence? A. Supporting detail B. Introduction C. Summary D. Main idea - n Ans✔ Correct answer: Supporting detail
The remaining answer choices are examples of proper subject-verb agreement. Qs Which of the following can lead to the formation of calcium kidney stones, which is when the urine contains more crystal-forming substances than urine can dilute? - n Ans✔ Consumption of oxalates The consumption of oxalates can lead to the formation of calcium kidney stones. Oxalates are found in fruits, vegetables, nuts, and chocolate. The consumption of seafood can lead to gout, as it is rich in uric acid. The consumption of carbohydrates can lead to tooth decay, as carbohydrates break down to form sugar. The consumption of salt can lead to high blood pressure. Qs What do ribosomes use to create proteins? - n Ans✔ RNA Ribosomes are made from RNAs and proteins called ribonucleoproteins. The DNA sequence in genes is copied into messenger RNA, which are then read by ribosomes to create proteins. Qs Express 432 cubic inches as a percentage of 1 cubic foot. - n Ans✔ Correct answer: 25%
12 inches = 1 foot (12 inches)³ = (1 foot)³ (12 × 12 × 12) = 1,728 cubic inches = 1 cubic foot To find the percentage, divide 432 cubic inches by 1,728 cubic inches and multiply by 100. 432/1728 × 100 = 25% Qs What is the primary purpose of catalysts? - n Ans✔ To increase a rate of reaction A catalyst is a substance that speeds up a rate of reaction but does not actively participate in it. It is, therefore, left chemically unchanged at the end of a reaction. Qs During the glycolysis process of cellular respiration, what is produced? - n Ans✔ Two ATP molecules, two pyruvate molecules, and two NADH molecules During the glycolysis process of cellular respiration, two ATP molecules, two pyruvate molecules, and two NADH molecules are produced. The glycolysis process takes place in the cytosol of the cell. Qs
Each daughter cell has 23 chromosomes at the end of meiosis. A daughter cell, or haploid gamete, has half the number of chromosomes that the parent cell has. The parent cell has 46 chromosomes. Qs Mitosis is a type of asexual reproduction. This cell division process occurs in how many stages? - n Ans✔ Four Mitosis is a four-stage process that creates two identical cells from one original cell. Prophase is the first and longest stage of mitosis. In this stage, the chromosomes become visible and the centrioles separate and move to opposite poles of the cell. Metaphase is the second stage of mitosis. In this stage, the chromosomes line up across the center of the cell and become connected to the spindle fiber at their centromere. Anaphase is the third stage of mitosis. In this stage, the sister chromatids separate into individual chromosomes and are pulled apart. Telophase is the fourth and last stage of mitosis. During this stage, the chromosomes gather at opposite ends of the cell and lose their distinct rod-like shapes. Two new nuclear membranes then form around each of the two regions of DNA and the spindle fibers disappear. Qs If one atom of element X with a charge of 3- reacts with two atoms of element Y with a charge of 1+ each, what is the charge of the final product, assuming all other variables are equal? - n Ans✔
There is a total of 2+ and 3- charges. Adding those together, we get a final charge of 1-. Qs It is known that the gene that codes for male pattern baldness depends on the gene for red hair. This type of interaction between alleles is known as which of the following? - n Ans✔ Epistasis Epistasis is a phenomenon that consists of the effect of one gene being dependent on the presence of one or more 'modifier genes' (genetic background). Similarly, epistatic mutations have different effects in combination than individually. Qs A tank loses 20 cubic inches of water after 3 hours through leakage. If the tank has 80, cubic inches of water, how much will remain in the tank after a total of two days? - n Ans✔ 79,680 cubic inches First, find out how many hours are in two days. 1 day = 24 hours 1 day x 2 = 24 hours x 2 = 48 hours In 3 hours, 20 cubic inches is lost. Set up a proportion to find out how much water is lost in 48 hours.
