1. If you have 10% solute, then you have 90% solvent because 90% + 10% = 100%..
2. If you have 20% solute, then you have 80% solvent because 80% + 20% = 100%.
3. The cell is hypotonic compared to the beaker because it has less solute inside of it. Usually people say the solution's tonicity and not the cell's tonicity though.

d.
capillary for the transport of carbon dioxide.
Answers
Answer:
The correct answer is d. Carbaminohemoglobin is formed in the capillary for the transport of carbon dioxide. Carbaminohemoglobin is a compound formed by the binding of carbon dioxide to hemoglobin, which occurs primarily in the capillaries of tissues. When carbon dioxide is produced as a waste product of cellular respiration, it diffuses out of the cells and into the capillaries. It then binds to hemoglobin in red blood cells, forming carbaminohemoglobin, which is transported back to the lungs for elimination during exhalation.

9.In the high substrate environment,would the enzymes work faster or slower or at the same speed as the medium substrate environment to break apart 100 substrates.
10.If the substrate totally changed shape,would the same enzyme be able to break apart 100 substrates? Yes or No.
11.Explain your reasoning supporting your answer in question 10.
Answers
In a high substrate environment, the enzymes would work faster than in a medium substrate environment to break apart 100 substrates. This is because when there are more substrates available, the enzymes have a higher chance of encountering and reacting with them, which leads to a higher reaction rate.
In the high substrate environment,would the enzymes work faster or slower?No, the same enzyme may not be able to break apart 100 substrates if the substrate changes shape.
Enzymes are highly specific in their action and can only bind to and react with specific substrates that fit their active site's shape. If the substrate changes shape, it may no longer fit the enzyme's active site, making it impossible for the enzyme to catalyze the reaction.
Therefore, the enzyme would not be able to break apart 100 substrates that are different in shape from the original substrate.

Answers
No, a change to a G would not result in a change in gene expression as the underlined C is a non-coding nucleotide and does not have any effect on gene expression.
Non-coding DNA corresponds to the portion of an organism's genome that does not code for amino acids, the building blocks of proteins. Some noncoding DNA sequences are known to play functional roles such as regulation of gene expression, whereas other regions of noncoding DNA have no known function. Other regions of non-coding DNA are important for protein assembly. By altering one of these regions, a variant (also known as a mutation) in the noncoding DNA can turn on the gene, causing the protein to be produced in the wrong place or at the wrong time. There are two types of SNPs in the coding region.Synonymous and non-synonymous SNPs. Synonymous SNPs do not affect the protein sequence, whereas non-synonymous SNPs change the amino acid sequence of the protein.

Answers
Regulating gene expression is a key process in both prokaryotic and eukaryotic cells. Controlling how an RNA transcript is splicedis NOT used in prokaryotic cells.
Here, correct option is D.
In prokaryotic cells, gene expression is regulated by controlling which mRNAs get translated into proteins by the ribosomes, controlling how often a gene is transcribed, and controlling how rapidly proteins are destroyed once they are made. In eukaryotic cells, these are all regulatory mechanisms used as well, but there are additional methods of regulating gene expression that are not found in prokaryotes.
These include controlling how an RNA transcript is spliced and regulating the rate of transcription through the use of transcription factors. Splicing involves the removal of introns from a pre-mRNA molecule, resulting in a mature mRNA molecule that can be translated into a functional protein.
Therefore, correct option is D.

A zygote is the product resulting from fertilization. During the journey of the zygote through the fallopian tubes, until its implantation in the uterus, it divides many times, thus going through different phases. From the 16 cells it is called a morula, this stage represents the set of cells from the division of the fertilized ovum, in the first stages of embryonic development. It represents an intermediate phase between the zygote and the blastocyst. The morula stage is characterized by the fact that the replicating cells are all the same size, and there is no differentiation of organs.
what is photosynthesis done by this process requires from sunlight and from abiotic matter. photosynthetis makes and for an ecosystem
Answers
Photosynthesis is a process carried out by plants, algae, and some bacteria that converts sunlight, carbon dioxide (\(CO2\)), and water (\(H2O\)) into glucose (\(C6H12O6\)) and oxygen (\(O2\)).
It is a crucial process for life on Earth as it provides the primary source of organic compounds and oxygen in ecosystems. During photosynthesis, sunlight is absorbed by chlorophyll and other pigments in the chloroplasts of plant cells. This energy is used to power the conversion of \(CO2\) and \(H2O\) into glucose and \(O2\). The glucose serves as an energy source for the organism, while oxygen is released as a byproduct into the atmosphere.
In addition to capturing sunlight, photosynthesis relies on abiotic matter such as \(CO2\) and \(H2O\) as reactants. \(CO2\) is obtained from the atmosphere through small openings called stomata in the leaves of plants, while \(H2O\) is typically absorbed from the soil through the plant's roots.
The process of photosynthesis plays a fundamental role in maintaining the energy flow and nutrient cycling within an ecosystem.

in island biogeography, what does species area relationship indicates? a. large islands that are far get more species that can fly or swim b. large islands increase the probability of extinction c. habitat heterogeneity provides suitable niches to colonize d. smaller habitat size reduces the probability of extinction
Answers
The species-area relationship in island biogeography indicates that larger habitat size reduces the probability of extinction. Habitat heterogeneity provides suitable niches to colonize, thus allowing for a higher number of species in the area. Therefore, the correct option is c.
Habitat heterogeneity provides suitable niches to colonize. Let's discuss the given options one by one.a. Large islands that are far get more species that can fly or swim: This option is incorrect because the number of species on an island is not determined by how far it is from the mainland but instead by the size of the island. Large islands increase the probability of extinction: This option is incorrect because larger islands provide more suitable habitats for a higher number of species and not for increasing the probability of extinction Smaller habitat size reduces the probability of extinction: This option is incorrect because smaller habitat size provides a lower number of suitable niches and habitats to colonize, which can increase the probability of extinction.
Thus, it can be concluded that habitat heterogeneity provides suitable niches to colonize in island biogeography.

The alpha subunit of the G protein that is associated with the epinephrine receptor, G s, A. opens Ca2 channels. B. closes Na channels. C. inhibits adenylate cyclase. D. activates adenylate cyclase. (
Answers
The alpha subunit of the G protein that is associated with the epinephrine receptor, Gs, activates adenylate cyclase. The correct option is D.
When epinephrine binds to its receptor, it triggers a conformational change in the receptor, causing it to activate the associated G protein, which consists of three subunits: alpha, beta, and gamma.
The activated alpha subunit of Gs dissociates from the beta-gamma complex and binds to adenylate cyclase, a membrane-bound enzyme that converts ATP to cyclic AMP (cAMP).
The binding of the alpha subunit to adenylate cyclase activates the enzyme, leading to an increase in intracellular cAMP levels, which in turn activates protein kinase A (PKA) and triggers downstream signaling pathways.
The activation of adenylate cyclase by the alpha subunit of Gs is a key step in the intracellular signaling cascade triggered by epinephrine and other G protein-coupled receptor agonists.
This signaling pathway plays a critical role in a variety of physiological processes, including the regulation of heart rate, blood pressure, and glucose metabolism. Therefore, the correct option is D.

an electrochemical cell is constructed such that on one side
Answers
An electrochemical cell is constructed in such a way that one side has a piece of copper metal placed in a copper sulfate solution, while the other side has a piece of zinc metal placed in a zinc sulfate solution.
Electrodes, the substance in which the redox reactions take place, are on both sides of the electrochemical cell. Copper, which is a good conductor, is used for the cathode. Zinc, on the other hand, is used as the anode. The anode and cathode are separated by a salt bridge or porous membrane in an electrochemical cell. The salt bridge provides a channel for ions to move freely between the anode and cathode sides. Electrons flow from the anode to the cathode via a wire, while ions travel through the salt bridge, establishing electrical neutrality on both sides of the cell.
Electrons are released from the zinc atoms and flow to the copper atoms through the external circuit, generating a current in the process. Zinc metal becomes zinc ions, while copper ions are reduced to copper metal on the cathode. The reaction is shown below as follows:$$\ce{Zn (s) → Zn^{2+} (aq) + 2 e-}$$$$\ce{Cu^{2+} (aq) + 2 e- → Cu (s)}$$In summary, the electrochemical cell has an anode, a cathode, and a salt bridge or a porous membrane. Electrons are released from the anode and travel to the cathode through an external circuit, generating an electric current. The salt bridge or porous membrane allows for the free flow of ions between the anode and cathode, maintaining electrical neutrality.
