You've been experiencing acid indigestion lately, and you'd like a quick fix for the problem. You do a little research on the Internet and discover that your problem is caused by excess stomach acid. In the pharmacy aisles, however, you're having a little trouble deciding what to purchase to address the problem. At the pharmacy counter, the clerk recommends that you purchase PEPCID AC or Alka-Seltzer tablets. You want to design an experiment to compare the effectiveness of Pepcid AC tablets and Alka-Seltzer tablets. Which of the following facts would be least likely to complicate your experiment and the analysis of your results?
a. PEPCIO AC and Alka-Seitzer tablets contain different ingredients.
b. PEPCID AC and Alka Seltzer tablets contain different concentrations of the antacid drug.
c. The recommended dosage for PEPCID AC and Alka-Seltzer tablets is different.
d. PEPCIO AC and Alka-Seltzer tablets are sold in different countries throughout the world,
Answer:
d. PEPCIO AC and Alka-Seltzer tablets are sold in different countries throughout the world.
Explanation:
When there is excess acid in the stomach then Alka-Seltzer tablet can be used. The Ph level of these tablets is higher than 7 because acidic reaction need to be stopped with an introduction of base.

3. If muscle contraction were an athletic game, calcium would be the most valuable player. Describe,
using some depth, the roles calcium is serving both inside the muscle fiber and outside at the NMJ.
Answer:
Explanation:
At the NMJ, calcium is responsible for "unlocking" the ligand gated channels, allowing AcH to be released into the synaptic cleft. When AcH binds and the AP moves down the sarcolemma and into the t-tubule, calcium is then released from the sarcoplasmic reticulum into the sarcoplasm. It then binds to the calcium subunit of troponin, causing a confirmational change in tropomyosin, exposing the active sites on actin. This allows the myosin heads to bind, causing muscle contraction.
What might happen to the Earth if human increase the amount of greenhouse gasses?
Explain your answer.''
Answer:
Global warming will occur
Explanation:
Greenhouse gases are special gaseous compounds that have this ability to trap HEAT due to their structural composition. They include; carbon dioxide (CO2), chlorofluorocarbons (CFC), methane (CH4) etc.
Anthropogenic activities such as burning of fossil fuels etc. release these gases into the atmosphere where they cause harm to the Earth. Greenhouse gases contribute immensely to the GLOBAL WARMING EFFECT, which is the increase in the temperature of the Earth surface. Therefore, if humans increase the amount of greenhouse gases in the atmosphere via their actions, there will be a GLOBAL WARMING occurrence.

Greg performed an experiment in which he measured the reaction rate of two different enzymes at varying pH is his real belts appear in the table below
Answer:
B. Enzymes have particular pH's at which they function best
Explanation:
The table in this question describes the reaction rate of two enzymes (enzyme 1 and 2) measured in mmol/min. According to the question, Greg performed an experiment in which he measured the reaction rate of two different enzymes at varying pH.
At pH 7-9, the reaction rate of enzyme 1 was more than that of enzyme 2 while from pH 9.5-11, the reverse was the case. This portrays that the reactivity of an enzyme is in response to the pH they are placed in. In other words, different enzymes have particular pH's at which they function best.

The adenine of the start codon is located at the +1 position. Use the DNA Mutations Interactive to determine which statements describe missense mutations. a substitution of G to U at position +13 in the sense strand a transition at position +12 in the antisense strand a transversion of C in the sense strand of the histidine codon a G nucleotide is inserted after position +1 in the antisense strand a deletion of the A at position +7 in the antisense strand an insertion of A between positions +7 and +8 on the sense s
Answer:
A transition at position +12 in the antisense strand
A deletion of the A at position +7 in the antisense strand
Explanation:
Given that Adenine of the start codon is located at the +1 position, The correct statements that describe missense mutations are
A transition at position +12 in the antisense strandA deletion of the A at position +7 in the antisense strandAdenine is a purine nucleobase that is used in the formation of nucleic acids

Plants can reproduce both sexually and asexually. What are some examples of sexual reproduction in plants? Select ALL that apply. Responses
Sexual reproduction in plants involves the fusion of male and female gametes to produce offspring with genetic diversity.
Mechanisms that facilitate sexual reproduction in plants are examples:
1)Pollination and Fertilization: Many plants rely on pollinators, such as bees, butterflies, or birds, to transfer pollen from the male reproductive structures (anthers) to the female reproductive structures (stigma) of flowers.
This process enables the fusion of sperm cells within the pollen with egg cells in the ovules, leading to fertilization.
Examples include flowering plants like roses, sunflowers, and apple trees.
2)Seed Production: After fertilization, the ovule develops into a seed. Seeds contain an embryo, formed by the fertilized egg, enclosed within a protective seed coat.
The mature seeds can disperse and germinate to give rise to new plants.
Various plant groups, including angiosperms (flowering plants) and gymnosperms (conifers and cycads), reproduce sexually through seed production.
3)Alternation of Generations: In plants with a complex life cycle, such as ferns, mosses, and liverworts, sexual reproduction involves an alternation between two distinct generations: the gametophyte and the sporophyte.
The gametophyte generation produces gametes (sperm and eggs) through specialized structures, while the fusion of gametes gives rise to the sporophyte generation, which produces spores.
4)Self-fertilization: Some plants have the ability to self-fertilize, where the pollen from the anther of a flower is transferred to the stigma of the same flower or another flower on the same plant.
This allows for sexual reproduction without the need for external pollinators. Self-fertilization can be seen in plants like tomatoes, peas, and certain grass species.

The function of the liver in humans is to maintain the [glucose] circulating in the blood stream at reasonably constant levels. This is so organs like the brain that use primarily glucose as their carbon source to produce energy via ATP have a steady supply of glucose. It also ensures that the levels of glucose in the blood stream do not get too high. Using the plots from problem 6, discuss why it makes sense that glucokinase in liver would behave differently than the hexokinase in other cells.
Answer:
Due to difference in function.
Explanation:
Glucokinase in liver behave differently than the hexokinase in other cells because glucokinase performs different function in the body. Glucokinase is an enzyme that is responsible for sensing the glucose level in the blood and also plays a key role in the storing of glucose as glycogen while on the other hand, this storing ability is absent in hexokinase so that's why the glucokinase in liver behave differently than the hexokinase in other cells.
What type of conservation will result in the greatest reduction in the burning of fossil fuels?
Answer:
Conservation of air.
Explanation:
Conservation of air will result due to greatest decrease in the burning of fossil fuels because fossil fuels greatly damage the air. The burning of fossil fuels produces carbondioxide gas in large amount that can be released in the atmosphere. This increase in carbondioxide gas in the air causes pollution that leads to global warming as well as health problems in humans. So we can conclude that decrease the use of fossil fuel leads to conservation of air.

which of the following is an example of a complementary base pair in DNA?
a. A-G
b. T-C
c. A-U
d. C-G
Answer: d. C-G
Explanation:
DNA or deoxyribonucleic acid is a structure which is common in every living organism. The two strands of the DNA are held together by base complementarity between the nitrogenous bases these bases are held by hydrogen bonding. Adenine always pairs with thymine by a triple hydrogen bonding and cytosine is always forms a pair with that of guanine by a double hydrogen bonding. So, in this given situation cytosine or C will show complementarity with that of guanine or G in a DNA structure helping in linking the two strands of DNA to form a single integrated double helical structure.
