Which of the following functions do Golgi bodies provide for the cell?
Help maintain cellular shape
Provide an extra layer of protection for the cell
Direct all cellular activities and act as the brain of the cell
Assist in the early stages of protein and lipid production
The function that the Golgi bodies provide for the cell is that they assist in the early stages of protein and lipid production. The correct option is D.
What are Golgi bodies?The Golgi apparatus is basically an organelle encountered in most eukaryotic cells. It is also referred to as the Golgi complex, Golgi body, or simply the Golgi.
It is a component of the cytoplasmic endomembrane system that packages proteins into membrane-bound vesicles before they are transported to their destination.
Proteins produced by ribosomes in the ER are packed in the Golgi apparatus, where lipids wrap them in a membrane that is then exported from cells.
Molecules entering the Golgi are charged, stored, and then released back into the cytoplasm (secretory vesicles).
The Golgi bodies function in the cell by assisting in the early stages of protein and lipid production.
Thus, the correct option is D.

What was the experimental variable we tested in the lodine Clock Reaction?
Answer:Experiment 1084-04: lodine Clock Reaction Purpose Determine the rate law for an iodine clock reaction and study the influence of st on that reaction abruptly that it can be as startling as the sudden sound of an alarm clock, hence the clock reaction Background Information chemical equations can be written for chemical reactions, only some will proceed while others do not. Among the ones that do proceed some reactions occur as soon as reactants are mixed, while others occur over minutes, hours, or n over several years. What are the controlling in predicting if a reaction will take place and the speed at which it will? Thermodynamics can answer the question, "Will the reaction take place?" Once the reaction is capable of proceeding kinetics can answer the other question, "How fast You will study the rate of the reduction of potassium persulfate, KoS Os, with sodium iodide, Nal. The net ionic equation for the reaction is eve The rate law for this reaction is in the form of And you will need to determine the reaction orders a and b, as well as the rate constant, k. Keep in mind that exponents can not be determined by jus looking at the chemical equation the reaction will take place? The rate of a reaction is defined as the increase in molar concentration of product of a reaction per unit time or the decrease in molar concentration of reectant per unit time. The usual unit for the rate is moles per liter per sec (mol/L s or M/s). Experimentally, it has been found that a reaction rate depends on the concentrations of the reactants. Usually a higher reactant concentration increases chance of collision among the reactants per unit time causing a faster reaction rate. An equation describing the relationship between the reaction rate and the concentration of the reactants You will need a way to determine how much of the reactants were spent over the given time period. Preferably, the concentrations of the reactants should not change too much; therefore the reaction rate can be represented by the initial concentrations of reactants (the initial-rate method). In this experiment, we will couple another reaction that consumes the product, 12 very quickly. The new reaction is the reduction of is called a rate law. For the elementary reaction Note that l2, which was produced in reaction (1) is consumed as fast as it is produced by reaction (2) to regenerate two l. i.e. [门is kept constant. By keeping [S203-9 much smaller than the initial concentration of S,0, we can assure [S20,1 is also kept nearly constant when S203 is completely consumed. At this point, the 12 is no longer eliminated by the reaction and starts to accumulate. This point is signaled by sudden appearance of the dark color from the interaction of l2 with starch indicator. We can measure the time elapsed till the color appears Rate k [AIB] The proportionality constant, k, is called the ate constant in the relationship between the rate nd concentrations. The rate constant has a fixed alue as long as the reaction temperature is held nstant. The exponents, a and b, are called the action order, and are frequently, but not always, egers. More importantly, they must be termined experimentally In this experiment you will determine the rate an iodine clock reaction, and study the effects of perature and a catalyst to the reaction rate ugh there are several versions of an iodine k reaction, all of them share a common feature: completion of the reaction is signaled by the en appearance of a dark purple color. This is characteristic of the interaction between cular iodine and starch. When the reaction is ed out correctly, this color will appear so According to the reaction stoichiometries of reactions (1) and (2), two molecules of S203 are required to counteract the consumption of one molecule of S20a2. Since S2032 would have been completely consumed when the dark purple color appeared, the Δ[SO ] should be % of the initial concentration of S203 15-08-2] = ½ initial [S,03-21
Food moved to the back of the mouth by the tongue causes all of the following EXCEPT covering the opening of the larynx by the epiglottis. pressure against the pharynx to initiate swallowing. elevation of the soft palate to seal off the nasal cavity. the swallowing center stimulates successive waves of muscle contraction in the esophagus. churning of the stomach contents.
Answer:
churning of the stomach contents.
Explanation:
When food is moved to the back of the mouth by the tongue (deglutition), it does not cause the churning of the stomach contents.
The churning of stomach contents occurs when the bolus from the mouth has entered through the lower esophageal sphincter into the stomach. Churning is the mixing of the bolus with digestive juices containing acids and enzymes secreted from the stomach lining.

"What if speciation occurred in humans?" Your essay should give a clear and precise example of speciation.
A student is asked to write an essay over the hypothetic prompt above. While brainstorming, the student came up with
four different ideas for their essay. Which idea is BEST aligned with the writing prompt and instructions?
The term speciation refers to the process by which two or more different species are produced from a single original population by different speciation mechanisms. Speciation occurs in three main steps: separation of the original population, divergence (trophic divergence, reproductive divergence, genetic divergence, etcetera), and isolation.
The most related option to speciation is B. Two populations of humans living on separate sides of the ocean. After a catastrophic event, travel across the ocean is not possible. After millions of years of separation, the two groups are no longer able to produce viable offspring together, but can still produce within their isolated groups.
Speciation occurs when the original population is divided into two groups. They inhabit different places and are exposed to varying environmental conditions. With time, each group experience many genetic changes. These mutations depend on each group´s environment and its ecological pressures, and they accumulate in time. Pressures act on individuals and make them adapt to the new environmental conditions. Generation after generation, the genotype of individuals will increase the fitness to survive and reproduce. Fixation of mutations will increase the difference between the two groups, up to the diverging point into two new species. Even is they get together again, these species will not be able to mate and produce offspring, and if they do, the new generations will not be viable or fertile.
The exposed case of two human population living on different sides of the ocean, is an example of allopatric speciation.
Allopatric speciation refers to the geographic separation of a continuous genetic background, originating two or more new geographically isolated groups. During these events of speciation, emerging new barriers impede genetic flow between groups, as the two new populations that are separated can not get together and mate anymore. These barriers might be geographical or ecological.
Different stages are involved in the allopatric speciation process:
• The emergence of the barrier.
• Interruption in the genetic flow
• Slow and gradual differentiation due to the occurrence of mutations in each population and their accumulation in time.
• Genetic divergence by natural selection and reproductive isolation, impeding the two groups to mate even if the barrier disappears.
• Prezigotic isolation mechanisms favored by selection a secondary contact between the new species occurs.
