a. A jellyfish know when to sting if a jellyfish feels threatened or comes into contact with its prey, the nerve impulses that trigger the nematocysts to fire are activated.

b. The jellyfish uses the phagocytic cells in response to the stimuli, that line its tentacles to capture and engulf its prey.

The phagocytic cells are specialized cells that help jellyfish capture and consume their prey. These cells, which are also known as cnidocytes, are located on the surface of the tentacles. They contain a specialized organelle called the nematocyst, which is the structure that injects venom into the target.

When a jellyfish touches a prey item, it triggers a stimulus that causes the phagocytic cells to activate the nematocysts. The nematocyst then fires, injecting the venom into the prey. After the venom is injected, the phagocytic cells engulf the prey and digest it using enzymes.

Jellyfish stinging is also a defence mechanism that they use to ward off predators. They can sense predators using their sensory structures, and they respond by firing their nematocysts, releasing the venom into their attacker.

The correct answer is "microvilli." Microvilli are microscopic, finger-like projections that extend from the apical surface of cells in a simple columnar epithelium. These small structures greatly increase the surface area available for absorption and play a crucial role in enhancing the efficiency of nutrient absorption along portions of the digestive tract.

Within the digestive tract, the simple columnar epithelium lines the surface of organs like the small intestine and large intestine, where nutrient absorption occurs. The presence of microvilli on the surface of these epithelial cells provides numerous benefits for efficient absorption.

Firstly, the abundance of microvilli significantly increases the total surface area available for absorption. This increased surface area allows for a greater contact between the luminal contents (such as digested food) and the absorptive cells, maximizing the absorption of nutrients like carbohydrates, proteins, and fats.

Secondly, the microvilli contain specialized transport proteins and channels that facilitate the absorption of specific molecules. These proteins help transport nutrients across the epithelial cells and into the bloodstream or lymphatic system. The dense packing of microvilli amplifies the presence of these transport proteins, further enhancing absorption efficiency.

Additionally, the microvilli possess a brush-like appearance due to their close arrangement. This brush border aids in trapping and retaining the digested food particles and nutrients, preventing their rapid movement through the digestive tract. This allows for sufficient time for absorption processes to occur.

In contrast to microvilli, cilia are hair-like structures present on certain types of epithelial cells. While cilia have important functions like moving mucus and facilitating the movement of substances, they are not directly involved in absorption along portions of the digestive tract.

Therefore, the modification of the simple columnar epithelium that enables efficient absorption along portions of the digestive tract is the presence of microvilli.

If potassium channels are blocked in an autorhythmic cell, the correct answer is (d) no repolarization.

In autorhythmic cells, potassium channels play a critical role in repolarizing the cell after depolarization. During the pacemaker potential, slow depolarization occurs due to the opening of funny channels and closing of potassium channels. The depolarization then leads to the opening of calcium channels, causing the rapid upstroke of the action potential. After the action potential peaks, potassium channels open, allowing potassium ions to flow out of the cell, which repolarizes the membrane potential back to the pacemaker potential.

If potassium channels are blocked, the cell cannot effectively repolarize after depolarization, which would result in a prolonged depolarization phase and a delay in the next pacemaker potential. This can lead to arrhythmias and other cardiac disorders.

Therefore, the correct option is D.

The fraction equivalent to 5/9 where the numerator is greater than 18 and the denominator is less than 40 is 600/1080.

To find a fraction equivalent to 5/9 where the numerator is greater than 18 and the denominator is less than 40, we can consider multiplying both the numerator and denominator of 5/9 by the same number to maintain the equivalent fraction.

Let's start by multiplying both the numerator and denominator by 2: (5 * 2) / (9 * 2) = 10/18.

The numerator, 10, is less than 18, so let's try multiplying by a larger number. Let's multiply both the numerator and denominator by 3: (10 * 3) / (18 * 3) = 30/54.

The numerator, 30, is greater than 18, but the denominator, 54, is greater than 40. We need to continue searching.

Next, let's try multiplying both the numerator and denominator by 4: (30 * 4) / (54 * 4) = 120/216.

Again, the numerator, 120, is greater than 18, but the denominator, 216, is greater than 40.

Finally, let's try multiplying both the numerator and denominator by 5: (120 * 5) / (216 * 5) = 600/1080.

The numerator, 600, is greater than 18, and the denominator, 1080, is greater than 40. However, we need to simplify the fraction.

Dividing both the numerator and denominator by their greatest common divisor, which is 120, we get (600/120) / (1080/120) = 5/9.

Therefore, the fraction equivalent to 5/9 where the numerator is greater than 18 and the denominator is less than 40 is 600/1080.

The rate at which thermal energy is absorbed by the water, sand, and air during the day will be as follows:

Water has a higher specific heat capacity than sand or air, which means that it takes more energy to raise the temperature of water than it does to raise the temperature of sand or air. Therefore, water will absorb thermal energy more slowly than sand or air.

In addition, water is a good conductor of heat, which means that heat is transferred through water more easily than it is through sand or air. This means that the heat from the sun will be distributed more evenly throughout the water, which will help to prevent the water from getting too hot.

Sand, on the other hand, is a poor conductor of heat. This means that the heat from the sun will be absorbed by the surface of the sand, and the heat will not be transferred to the deeper layers of sand. This will cause the surface of the sand to get very hot, while the deeper layers of sand will remain relatively cool.

Air is also a poor conductor of heat. However, air is constantly moving, which helps to distribute the heat from the sun more evenly. This means that the temperature of the air will not vary as much as the temperature of the sand or water.

The passage of digested food from the digestive tract into the cardiovascular and lymphatic systems is called absorption.

Absorption is a crucial process in the digestive system as it allows for the nutrients obtained from food to enter the bloodstream and reach the cells in the body. The process of absorption primarily occurs in the small intestine, where the nutrients are transported across the intestinal wall and into the blood vessels and lymphatic vessels. Once absorbed, the nutrients are carried by the bloodstream to various organs and tissues in the body, where they are utilized for energy, growth, and repair.

In conclusion, absorption plays a vital role in the digestion and utilization of nutrients from the food we eat.

Genes will assort independently and are referred to as being unlinked during meiosis if they are located on distinct chromosomes or distantly from one another on the same chromosome.

Due to cross-over, genes that are on the same chromosome but located far apart assort separately (homologous recombination). This is a mechanism where homologous chromosomes randomly exchange matched pieces at the start of meiosis.

During meiosis, a process known as independent assortment causes the chromosomes to randomly move to different poles. After meiosis, a gamete will have 23 chromosomes, but independent assortment means that each gamete will have 1 of numerous different combinations.

Explanation:

"The ultimate goal of cellular respiration is  take carbohydrates, disassemble them into glucose molecules, and then use this glucose to produce energy-rich ATP molecules."  

Most of the metabolic activity in the cell occurs in the endoplasmic reticulum.

The endoplasmic reticulum (ER) is a network of flattened sacs, tubules, and vesicles enclosed by a single unit membrane. It extends throughout the cytoplasm in a manner similar to the plasma membrane. The ER is classified into two types: the rough endoplasmic reticulum (RER) and the smooth endoplasmic reticulum (SER). The rough endoplasmic reticulum is covered in ribosomes, giving it a textured appearance. Proteins are synthesized and processed in this region. The proteins made on ribosomes that are connected to the rough endoplasmic reticulum enter the cisternal space and are then modified. The cisternal space of the rough endoplasmic reticulum is contiguous with the perinuclear space and is in contact with the outer nuclear membrane. The smooth endoplasmic reticulum, on the other hand, is devoid of ribosomes and is responsible for the synthesis of various lipids, including phospholipids, steroid hormones, and fatty acids. It is also responsible for carbohydrate metabolism, drug detoxification, and the storage and release of calcium ions into the cytoplasm.

Explanation:

Elevated fibrinogen levels result in hypercoagulable state , which increases the risk of a coronary or cerbrovascular incident.

A hypercoagulable state in medicine refers to a condition in which there is an abnormal increase in the tendency toward the clotting of blood also known as blood coagulation.

When fibrinogen levels are high, there is an increase in clot stiffness, increase in resistance of the clot to fibrinolysis as well as an increased blood viscosity.

Treatment with heparin can lead to increased levels of triacylglycerols in the blood due to the effect it has on lipoprotein lipase (LP lipase).

a) The function of LP lipase is to break down triacylglycerols into free fatty acids and glycerol, which can then be taken up by cells and used for energy or storage. LP lipase is attached to the capillary endothelium through proteoglycans.

b) The activator of LP lipase is apolipoprotein C-II (apoC-II), which is found on the surface of chylomicrons and very low-density lipoproteins (VLDL).

c) The mechanism of hypertriacylglycerolemia development in patients treated with heparin involves the binding of heparin to LP lipase. Heparin can dislodge LP lipase from the capillary wall, preventing it from effectively breaking down triacylglycerols. This results in an accumulation of triacylglycerols in the blood, leading to increased levels of triacylglycerols.

In summary, heparin treatment can disrupt the function of LP lipase, which is responsible for breaking down triacylglycerols. This disruption leads to increased levels of triacylglycerols in the blood.
