STEM Enzymes Honors Biology Question:
Explain how you determined that Claire had low enzyme production. Use your experimental data to explain how you ruled out active site mutations and abnormal pH
Answers
To determine that Claire had low enzyme production, we likely performed an experiment where we measured the activity of the enzyme in question in a sample of Claire's tissue or bodily fluids (depending on the type of enzyme).
We may have measured enzyme activity in a variety of ways, such as tracking the rate of a reaction that the enzyme catalyzes or measuring the amount of product produced by the enzyme over a set period of time. We would then compare Claire's enzyme activity levels to the activity levels of a control group or a reference range for that particular enzyme.
If we found that Claire's enzyme activity was significantly lower than the control group or reference range, this would indicate that she had low enzyme production.
Overall, by ruling out potential causes for low enzyme activity such as active site mutations and abnormal pH conditions, we could determine that Claire's low enzyme production was likely the root cause of her enzyme deficiency.

Describe the construction of an artery, vein, and capillary including names of the layers, tissues that make up the layers and the function of each vessel.
Answers
Arteries, veins, and capillaries are all types of blood vessels that play an important role in the circulatory system. The construction of each vessel includes multiple layers, each with its own unique function.
Artery:
Arteries have three layers: tunica intima, tunica media, and tunica externa. The tunica intima is composed of endothelial cells, providing a smooth surface for blood flow. The tunica media contains smooth muscle and elastic fibers, allowing arteries to maintain blood pressure and contract or expand. The tunica externa is made up of connective tissue, providing structural support. The primary function of arteries is to transport oxygen-rich blood from the heart to various body tissues.
Vein:
Veins also have three layers: tunica intima, tunica media, and tunica externa. The tunica intima consists of endothelial cells, like in arteries. The tunica media is thinner in veins and contains less smooth muscle and elastic fibers. The tunica externa is also composed of connective tissue. Veins contain valves to prevent backflow of blood. Their primary function is to transport oxygen-poor blood back to the heart.
Capillary:
Capillaries have a single layer called the endothelium, made up of endothelial cells. They lack tunica media and tunica externa. This thin structure allows for efficient exchange of nutrients, oxygen, and waste products between blood and surrounding tissues. Capillaries connect arteries and veins, facilitating blood flow throughout the body.

Answers
The effect of antidiuretic hormone (ADH) on water retention in the collecting duct is that ADH stimulates aquaporin synthesis.
Anti diuretic hormone (ADH) is a hormone that aids in blood vessel constriction and aids the kidneys in managing the body's salt and water levels. This aids in regulating both blood pressure and urine production. This increases the water permeability of the collecting duct (nephrons are physically connected to a minor calyx or the renal pelvis by a network of tubules and ducts that make up the kidney's collecting duct), allowing more water to be reabsorbed into the bloodstream, leading to increased water retention. ADH release is also stimulated by an increase in blood osmotic pressure and by angiotensin II. However, renin does not convert ADH to angiotensin II; renin is involved in the production of angiotensin I, which is then converted to angiotensin II by the angiotensin-converting enzyme (ACE).

What is the name of the female reproductive organ whorl in flowering plants?
A. Calyx
B. Corolla
C. Androecium
D. Gynoecium
Answers
The female reproductive organ whorl in flowering plants is called Gynoecium.
The gynoecium, or female reproductive organ, consists of the carpel. often refers to the several floral structures that work together to create the ovules that will go on to form the fruit and seeds. In spite of its common designation as the flower's "female" organ, the gynoecium does not directly create female gametes but rather megaspores, each of which grows into a female gametophyte that in turn produces egg cells.
Gynoecium comes in three varieties: monocarpous, apocarpous, and syncarpous. Monocarpous gynoecium is made up of only one carpel. The flower has a single stigma, style, and ovary. An apocarpous gynoecium is made up of several carpels that are isolated from one another. On a single flower, they have several stigmas, styles, and ovaries. Many carpels have fused together to form a syncarpous gynoecium. Tomatoes, mangoes, and coconuts are frequent flowers with syncarpous gynoecium.

The break down of the freshwater aquatic ecosystem is given below.
Part A
For the purpose of this exercise, I will choose the Great Salt Lake in Utah, USA as my model for a freshwater aquatic ecosystem. The Great Salt Lake is the largest saltwater lake in the Western Hemisphere, and is known for its high salinity levels and unique chemistry.
The lake is fed by several rivers, including the Jordan and Bear rivers, and has no outlet, which contributes to its high salinity levels.
The lake also experiences seasonal changes in temperature and light availability, with warmer temperatures and more sunlight in the summer and cooler temperatures and less sunlight in the winter.
What is the freshwater aquatic ecosystem about?Part B
The Great Salt Lake ecosystem is home to a variety of organisms at different consumer levels. Some examples include:
Producers:
Phytoplankton: Microscopic algae that are the base of the food web and are primary producersSodium chloride-tolerant plants like alkali bulrush and saltgrassPrimary Consumers:
Brine flies: these insects feed on the phytoplanktonbrine shrimp: these tiny crustaceans feed on the phytoplanktonSecondary Consumers:
Black brant and other waterfowl: these birds feed on the brine flies and shrimpWhite pelican: These birds feed on the brine shrimpTertiary Consumers:
Coyotes and foxes: These mammals feed on the waterfowl and other small animalsAmerican avocet: These birds feed on the brine flies and shrimpQuaternary Consumers:
Humans: they may fish or hunt the aquatic species and use the lake's resourcesPart C
This is a possible food web for the Great Salt Lake ecosystem:
Phytoplankton -> Brine Flies -> Black Brant -> CoyotesPhytoplankton -> Brine Shrimp -> Pelican -> FoxesSodium chloride-tolerant plants -> American avocet -> HumansPart D
One natural change that currently affects the Great Salt Lake ecosystem is the seasonal variation in water levels. The lake's water level can fluctuate greatly depending on the amount of precipitation and evaporation.
During drought periods, the lake's water level can drop dramatically, which affects the competition for food resources in the ecosystem.
Part E
One human activity that currently affects the Great Salt Lake ecosystem is water diversion for irrigation and human consumption. The lake's water level is also affected by the diversion of water from the Jordan and Bear rivers, which feed into the lake. This water diversion decreases the amount of fresh water that enters the lake, which affects the amount of phytoplankton and other producers in the ecosystem.

State one similarity and one difference between parasitic and predatory modes of feeding
Answers
Answer:
One similarity between parasitic and predatory modes of feeding is that both involve the ingestion of other organisms for nutrition. In both cases, the organisms that do the feeding (the parasites or predators) obtain their food from other organisms (the host or prey), which they consume and use to nourish themselves.
One difference between parasitic and predatory modes of feeding is the relationship between the predator and its prey. In predatory feeding, the predator and its prey are typically separate and distinct organisms, and the predator actively hunts and kills its prey for food. In parasitic feeding, the parasite and its host are typically closely associated, and the parasite typically lives on or inside the host, feeding off of its nutrients or tissues. This relationship between the parasite and its host is often harmful to the host, while the relationship between the predator and its prey is typically not harmful (as long as the predator is not over-consuming its prey).

How to creates an environment conducive to tissue formation
Answers
Creating an environment conducive to tissue formation requires a combination of factors such as proper nutrition, hydration, oxygenation, and protection from infection. It is essential to consume a balanced diet that includes adequate protein, vitamins, and minerals to support tissue growth and repair.
Hydration is also critical as it helps transport nutrients to the tissues and aids in the removal of waste products. Oxygenation is another vital factor, and maintaining proper breathing and blood flow can help deliver oxygen to the tissues, which is necessary for their survival and function. Additionally, it is crucial to protect the tissues from infection by practicing good hygiene and avoiding exposure to harmful pathogens. In summary, creating an environment conducive to tissue formation involves maintaining a healthy and balanced lifestyle that supports proper nutrition, hydration, oxygenation, and infection prevention.

Answers
Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of the chart referred to in the question. However, what appears to be the case is that the three nitrogenous bases represent codons (and the missing chart is the codon chart). The mutation that has the potential to cause more damage will be the one that would change the amino acid formed from the codon change.
A. CAU to CAC: The codons CAU and CAC both form the amino acid histidine and thus is not expected to cause a major damage.
B. UGU to UGC: The codons UGU and UGC both form the amino acid cysteine and thus is not expected to cause a major damage.
C. UCU to UUU: Codon UCU forms the amino acid serine while the codon UUU forms the amino acid phenylalanine. Thus, this eventual change in the amino acid formed has the potential to cause a major damage and thus option C is the correct option.
NOTE that a codon is a sequence of three DNA/RNA nucleotides that corresponds to a single amino acid.

Answers
The transport properties that involve the elimination of concentration differentials are Diffusion, Osmosis , Active Transport and Bulk Flow.
Diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration. It occurs due to the random motion of particles and is driven by the concentration gradient until equilibrium is reached. Osmosis is the diffusion of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. It aims to equalize the concentration of solute on both sides of the membrane.
Active transport is a process that requires the expenditure of energy to move molecules or ions against their concentration gradient. It involves the use of carrier proteins embedded in the cell membrane to transport specific substances across the membrane. Bulk flow is the movement of fluids, such as blood or sap, in response to a pressure gradient. It involves the coordinated movement of a large number of molecules or ions in a particular direction.
