. determine which curve represents an enzyme's reaction velocity without any inhibitor present, which curve represents the velocity in the presence of a noncompetitive inhibitor, and which curve represents the velocity in the presence of a competitive inhibitor.
Answers
The curve represents an enzyme's reaction velocity without any inhibitor present is the curve where the reaction rate reaches its maximum level,
The curve represents the velocity in the presence of a noncompetitive inhibitor is the curve where the reaction rate does not reach its maximum rate
the curve represents the velocity in the presence of a competitive inhibitor isthe curve where the reaction rate is inhibited at the start and manages to reach its maximum level.
Enzymes are biomolecules that function as catalysts, namely compounds that accelerate the process of a chemical reaction. Cells produce enzymes which are generally in the form of proteins as catalysts to help metabolism in cells which are concentrated in certain organelles where reactions take place. Enzymes will accelerate the rate of chemical reactions, namely changes in the concentration of reactants or products in a unit time. Without an inhibitor, the chemical reaction rate curve will run quickly to reach its maximum to form a new product as a result of the reaction.
Inhibitor is a chemical substance that can inhibit or slow down a chemical reaction. In non-competitive inhibitors the reaction inhibiting molecule will attach to the active site of the enzyme so that the substrate cannot attach. Therefore the reaction rate will decrease so that the curve will show the reaction will run slowly because it does not reach its maximum. Noncompetitive inhibitors slow down the overall rate of a chemical reaction.
While competitive inhibitor molecules will compete with the substrate for attachment to the active site of the enzyme. So the enzyme cannot produce the enzyme substrate complex. The curve will show that competitive inhibitors only inhibit at the beginning of a chemical reaction, in the end the reaction rate will reach its maximum level with the addition of many substrates.

explain what it would mean for an association to exist between eye and hair color
Answers
An association between eye and hair color means that there is a relationship or correlation between the two traits, suggesting that they are not entirely independent of one another. This association may be due to shared genetic factors or heredity, as genes often determine both eye and hair color.
The existence of such an association would indicate that the presence of a specific eye color may be more likely to occur alongside a particular hair color.
For example, individuals with brown eyes might have a higher probability of having brown hair, while those with blue eyes could be more likely to have blonde hair. This is not to say that all people with blue eyes will have blonde hair, but rather that the occurrence of these two traits together is more common than expected by chance alone.
Understanding the association between eye and hair color can be valuable in fields such as genetics, anthropology, and forensics, as it may help in identifying certain patterns or trends within populations.
However, it is essential to keep in mind that while such associations may exist, they do not imply causation, and many exceptions to these patterns can be observed in diverse populations.

The word that goes with the blank labeled as A is protein, as protease helps in protein digestion.
What are digestive enzymes?Digestive enzymes are proteins that the body produces to help break down food and aid digestion.
Digestion is the process by which your body uses the nutrients found in food to provide energy, help it grow, and perform vital functions.
Digestive enzymes are essential for splitting down the food you eat. These proteins hasten chemical reactions that convert nutrients into substances that can be absorbed by your digestive tract.
Digestive enzymes are present in your saliva. They are also released by some of your organs, including the pancreas, gallbladder, and liver.
Proteolytic enzymes (proteases) are protein-degrading enzymes, that convert proteins into amino acids. Animals, plants, fungi, and bacteria all produce enzymes.

a world without us What were the two species of monkeys forced to do because of their reduced population?
Answers
Alarmingly, populations of 75% of primate species are falling, and 60% are currently endangered.
The expansion of industrial agriculture, extensive cattle ranching, logging, oil and gas drilling, mining, building of dams, and the creation of new road networks in areas where primates range are the main causes of the situation. Additionally, there are local and global market demands that have contributed to significant habitat loss as well.
Together with growing dangers like climate change and anthroponotic illnesses, other significant causes include increased bushmeat hunting, the illegal traffic in primates as pets and in their body parts, and these. These factors frequently work together to exacerbate decreases in the primate population. Given that the areas of primate range overlap significantly with those of a sizable, fast expanding, and markedly impoverished human population, urgent global attention is required to prevent the impending threat of primate extinction and to address local human needs in a sustainable manner. It is critical to increase public and scientific awareness of the situation facing primates worldwide and the harm their extinction would cause to ecosystem health and human society.

A lichen is an organism that structurally appears to be a single organism. But a lichen is actually two different organisms—a fungus and green algae—living together as one organism. The fungal partner derives its nutrition from the photosynthesizing algae. How does a lichen differ in its photosynthetic activity from Elysia chlorotica, the sea slug that’s considered to be a photosynthesizing animal?
A.
In lichens, the fungi photosynthesize on their own, while Elysia chlorotica forms a relationship with a photosynthesizing plant.
B.
In lichens, the relationship with the algae lasts throughout the life cycle, but in Elysia chlorotica, the relationship occurs only during the immature juvenile stage of the slug’s life cycle.
C.
Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells.
D.
In lichens, the association between the fungi and algae is permanent, while Elysia chlorotica associates with a photosynthesizing organism only when it requires food.
Answers
Answer:
B. Cycle
Explanation:
Lichen performs photosynthesis with the assistance of an algal partner, but Elysia chlorotica incorporates the chloroplast from an algal partner, which is how lichens vary from Elysia chlorotica in this regard, hence option C is correct.
How does lichen photosynthesize?A process known as photosynthesis is one in which green plants and some photosynthetic algae produce their own food, glucose, using carbon dioxide and water in the presence of light.
Lichen is a symbiotic association between an algal component that produces food and a dominant partner fungus that gives the lichen its thallus form and fruiting bodies. A particular species of mollusc called Elysia chlorotica uses the chloroplast of an algal partner to carry out the photosynthesis process.
Therefore, Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells, hence option C is correct.

During an action potential, the rapid decrease in sodium permeability and simultaneous increase in potassium permeability is responsible for __________.
Answers
During an action potential, the rapid decrease in sodium permeability and simultaneous increase in potassium permeability is responsible for Repolarization.
K+ departs the cell after Na+, which enters the cell first. Ions can move freely across the axon membrane because of the difference during the action potential.Because sodium contains a positive charge, the neuron becomes more positive and depolarized. Potassium channels take longer to open. As soon as the cell does open, K+ rushes out, reversing the depolarization known as repolarization.Sodium channels close during the peak of the action potential when potassium leaves the cell. When potassium ions are effluxed, the membrane potential is lowered or the cell becomes hyperpolarized.Outside of the cell, the concentration of Na+ is greater than inside the cell. while the concentration of K+ is is greater inside the cell than outside.

FILL IN THE BLANK. marathon runners have more ___ in the cells of their muscles to allow for greater atp production
Answers
Marathon runners have more mitochondria in the cells of their muscles to allow for greater ATP production.
Mitochondria are the powerhouses of the cell responsible for producing ATP, the primary energy currency of cells. During intense physical activities such as marathon running, the demand for ATP increases significantly to meet the energy needs of the muscles.
To meet this increased demand, the body adapts by increasing the number of mitochondria in the muscle cells. Mitochondria are membrane-bound organelles that carry out aerobic respiration, a process that generates ATP through the breakdown of glucose and other fuel molecules in the presence of oxygen.
The presence of more mitochondria in the muscle cells of marathon runners allows for a higher capacity to produce ATP. This is because each mitochondrion contains enzymes and electron transport chains that participate in the oxidative phosphorylation process, ultimately leading to ATP synthesis.
The increased number of mitochondria in marathon runners' muscle cells enhances their aerobic capacity and endurance. It enables them to efficiently utilize oxygen and fuel molecules to sustain prolonged physical activity, thereby supporting their performance during long-distance running.
