All of the following supply blood to the lower limbs EXCEPT . -femoral artery -descending aorta -external iliac artery -popliteal.
Answers
The blood vessel which doesn't supply blood to lower limb from the given options is Descending aorta.
The descending aorta is a major blood vessel that supplies oxygenated blood to various parts of the body. It originates from the aortic arch and extends downward through the thoracic and abdominal cavities before dividing into the common iliac arteries. Although the descending aorta does contribute to the blood supply for the lower limbs, it does so indirectly by giving rise to the external iliac arteries.
The external iliac artery is the primary blood vessel that supplies blood to the lower limbs. As it passes beneath the inguinal ligament, it becomes the femoral artery. The femoral artery then branches into various arteries that supply blood to the thigh, knee, and lower leg, including the popliteal artery. The popliteal artery supplies blood to the knee joint and muscles in the region, and further divides into the anterior and posterior tibial arteries to provide blood to the lower leg and foot.
In summary, while the descending aorta plays a role in providing blood to the lower limbs, it does not directly supply blood to them. The femoral artery, external iliac artery, and popliteal artery all have direct roles in supplying blood to the lower limbs.

C) Increase ∆G‡
D) More negative ∆G’°
E) Increased k2
F) Decreased ∆G‡
G) Increased Keq
Why? Justify your answer to every letter using your knowledge of enzyme action and activity
Answers
Answer:
A) Decreased K’eq - This is not correct. Enzymes lower the activation energy required for a reaction to occur, which leads to an increase in the rate of the reaction (k1) and a decrease in the equilibrium constant (Keq)
B) Increase k1 - This is correct. Enzymes lower the activation energy required for a reaction to occur, leading to an increase in the rate of the reaction (k1).
C) Increase ∆G‡ - This is not correct. Enzymes lower the activation energy required for a reaction to occur, which leads to a decrease in the standard free energy change (∆G‡)
D) More negative ∆G’° - This is not correct. Enzymes lower the activation energy required for a reaction to occur, which leads to a decrease in the standard free energy change (∆G‡) and as a result, ∆G'° will become less negative.
E) Increased k2 - This is not correct. Enzymes do not affect the rate constant for the reverse reaction (k2)
F) Decreased ∆G‡ - This is correct. Enzymes lower the activation energy required for a reaction to occur, which leads to a decrease in the standard free energy change (∆G‡)
G) Increased Keq - This is not correct. Enzymes lower the activation energy required for a reaction to occur, which leads to a decrease in the equilibrium constant (Keq)
In summary, enzymes catalyze reactions by lowering the activation energy required for a reaction to occur, leading to an increase in the rate of the reaction (k1) and a decrease in the standard free energy change (∆G‡) and equilibrium constant (Keq).
The enzyme that is catalysing the straightforward reaction has a lowered activation energy, increased k1, and increased k2.
Enzymes don't alter a biological reaction's equilibrium state, to put it briefly. G0 and Keq do not change. Instead, the enzyme speeds up the reaction by lowering the activation energy required for it to happen.
A catalyst accelerates the forward and backward reactions by the same precise amount. When the rates of the forward and back reactions are identical, dynamic equilibrium is reached. There is no requirement for a change in the position of equilibrium if a catalyst speeds up both reactions equally.

when stimulated by an antigen presenting cell, t cells are stimulated to become t helper type 1 or t helper type 2 cells. what determines which they become?
Answers
A naive helper T cell can develop into either a TH1 or TH2 effector helper cell when an antigen-presenting cell activates it in a peripheral lymphoid tissue. The cytokines that these two types of functionally separate effector helper T cells release allow for easy differentiation.
The two types of T cells perform indistinctly due to their various cytokine patterns. B-cell antibody production, especially IgE responses, is generally well supported by TH2 cells. The opposite is true; TH1 cells cause delayed-type hypersensitivity reactions.
A helper T cell can assist in the activation of other cells once it has been transformed into an effector cell by an antigen-presenting cell. It accomplishes this by both exhibiting costimulatory proteins on its surface and secreting a range of cytokines.

Answer:
4. Three ways in which ocean water varies are salinity, temperature, and pressure.
5. The temperature of ocean water varies with the location and seasons.
6. Water temperature decreases as you move from the surface towards the ocean floor. This is because sunlight warms the surface water, but deeper water is much colder.
7. Scuba divers are prevented from going deeper than 40 meters below the surface due to the increased pressure at greater depths, which can be dangerous without proper training and equipment.
8. Ocean floor features such as trenches and mid-ocean ridges form through tectonic plate movements. When plates collide or separate, they can cause the ocean floor to be pushed up or down, creating these features. Trenches, for example, are formed when one tectonic plate is forced underneath another plate, causing a deep depression in the ocean floor. Mid-ocean ridges, on the other hand, are formed when plates move apart, allowing magma to rise to the surface and create new ocean floor.

the cell membrane forms around another substance, for example, how the amoeba gets its food
Answers
The process by which the cell membrane forms around another substance is called endocytosis. This is how the amoeba gets its food.
Amoebas use a type of endocytosis called phagocytosis, where they surround their food with their cell membrane and then engulf it into their cell. This allows the amoeba to take in larger particles of food that would not be able to pass through the cell membrane on their own. Once inside the cell, the food is broken down and the nutrients are used for energy and growth. Endocytosis is an important process for many types of cells, as it allows them to take in nutrients and other substances from their environment.
It seems like you're asking about the process by which a cell membrane forms around another substance, such as how an amoeba consumes its food. This process is called "phagocytosis." Here's a step-by-step explanation:
1. Detection: The amoeba detects the presence of a food particle nearby, such as a bacterium or a smaller organism.
2. Pseudopodia formation: The amoeba extends its cell membrane by forming structures called pseudopodia (false feet) that move towards the food particle.
3. Engulfment: The pseudopodia surround the food particle, and the cell membrane starts to form around it.
4. Membrane fusion: As the pseudopodia continue to surround the food particle, the cell membrane eventually fuses together, forming a sealed, internal compartment called a phagosome.
5. Digestion: The phagosome containing the food particle fuses with a lysosome, an organelle containing digestive enzymes. These enzymes break down the food particle into smaller nutrients.
6. Absorption: The nutrients are then absorbed by the amoeba and used for growth and energy production, while any remaining waste materials are expelled from the cell.
In summary, the cell membrane forms around another substance through a process called phagocytosis, which allows amoebae to consume and digest their food.

One property of water that makes it unique is its density. Which example describes a result of this property? Fish can continue to swim under floating ice on a lake. Trees transport water from their roots to their leaves. Water strider insects walk on the surface of pond water. Plants receive enough light to grow under the surface of a lake.
Answers
Answer:
Fish can continue to swim under floating ice on a lake.
Explanation:
Water is known to be a unique molecule due to the properties it posseses. According to this question, one of these properties is DENSITY. The hydrogen bonds that holds the molecules of water together makes this possible. Ice, which is the solid state of water, is less dense than liquid water because the hydrogen bonds becomes tightly packed together.
This causes ice to float on liquid water. Hence, in a lake, the less dense feature of ice makes it float on water, causing fishes to continue to swim effectively under floating ice on the lake.
Biomagnification is... concentration of a contaminant stays the same as you move to higher trophic concentration of a contaminant increases as you move to higher trophic level concentration of a contaminant increases as an individual grows concentration of a contaminant stays the same as an individual grows
Answers
Answer: Biomagnification refers to the process by which the concentration of a contaminant increases as you move to higher trophic levels in a food chain or food web. In other words, as organisms consume other organisms, the contaminants present in the prey accumulate and become more concentrated in the bodies of the predators.
To understand this process, let's consider an example involving a water ecosystem. Suppose a pollutant is released into the water, such as a pesticide or heavy metal. The primary producers, such as algae or aquatic plants, absorb small amounts of the contaminant from the water. As herbivorous organisms consume these primary producers, they ingest the contaminants along with their food.
Since the contaminant is not easily broken down or eliminated from the organisms' bodies, it accumulates over time. As a result, the concentration of the contaminant becomes higher in the herbivores than in the primary producers. Now, when carnivorous organisms consume the herbivores, they not only accumulate the contaminant from their own food but also from all the prey they have consumed. This leads to an even higher concentration of the contaminant in the carnivores.
Therefore, biomagnification describes the phenomenon where the concentration of a contaminant increases significantly as you move up the food chain or trophic levels. The highest concentration of contaminants is often found in top predators, such as large fish, birds of prey, or mammals, which can have adverse effects on their health and reproductive capabilities.
It's important to note that biomagnification primarily occurs for persistent and non-biodegradable contaminants that cannot be easily metabolized or excreted by organisms. These contaminants are often lipophilic (fat-soluble), which allows them to accumulate in fatty tissues and remain in the organism's body for long periods, leading to biomagnification.

In a biofloc technology system and a stagnant-renewal culture system, the effects of dietary Lactobacillus plantarum (KC426951) on the growth and innate responses of Nile tilapia Oreochromis niloticus were assessed (SRCS).
What are the four treatments?
Four treatments—SRCS without probiotic (T1), SRCS with probiotic (T2), biofloc without probiotic (T3), and biofloc with probiotic—were used during the experiment's ninety days (T4). Probiotics were administered at a level of 2 108 CFU kg-1 diet. At the conclusion of the trial, BFT treatments considerably (P 0.05) outperformed control groups in terms of mean final weights, specific growth rates, feed conversion ratios, and total biomass.Probiotics had no discernible effects on these variables in either culture system. In the meantime, probiotic supplementation dramatically improved skin mucosal measures such as total protein (TP), lysozyme (LYZ), alkaline phosphatase (ALP), and protease (PRO) activity. In comparison to other therapies, T4 therapy showed a considerably greater LYZ and ALP activity in mucus. Additionally, fish that had been given probiotic supplements showed noticeably increased serum alternative complement activity. The activity of superoxide dismutase was found to be higher in T4 than in SRCS groups.
