During swallowing, muscles draw the soft palate and uvula upward  primarily to prevent food or fluid from entering the nasal cavity. Option(C)

As the bolus of food or liquid moves toward the back of the mouth, the upward movement of the soft palate and uvula creates a seal between the oral cavity and the nasal cavity.

This prevents any inadvertent passage of food or liquid into the nasal passage, directing it instead toward the esophagus. This protective mechanism ensures that the ingested material reaches the intended destination and avoids potential complications or discomfort associated with the nasal cavity.

A bolus refers to a small, compact mass of food or liquid that is formed and swallowed during the process of eating and drinking.

Explanation:

The process of expelling urine from the urinary bladder is called urination or micturition.

Urination or micturition are terms used to describe the act of releasing urine from the bladder. The ability of the urinary system to remove waste and maintain fluid balance is a crucial bodily function. The coordinated activity of several tissues, including the bladder, urethra, and related muscles, is required for the complicated process of urination. Sensational signals are delivered to the brain when the bladder is full, which causes the conscious need to pee. Urination can be started and controlled by using voluntary control of the external urethral sphincter. When urinating, the bladder contracts and the pee leaves the body through the urethra.

About the efficiency of energy transfer in an ecosystem: Option (c) is true: The efficiency of energy transfer in an ecosystem is usually less than 20%

Energy transfer in an ecosystem is an important process that enables the organisms in the food chain to gain energy.  In an ecosystem, energy transfer takes place from one organism to another through different levels of the food chain. The first level consists of primary producers like green plants, which utilize solar energy to manufacture their food by photosynthesis. Then, primary consumers like herbivores feed on plants, and secondary consumers like carnivores feed on primary consumers, and so on.The energy transfer in an ecosystem occurs in a one-way process, from the sun to the producers, and then from the producers to consumers, and finally to the decomposers.

However, it has been observed that the efficiency of energy transfer in an ecosystem is usually less than 20%. This means that only 10-20% of the energy that is stored in the food consumed by an organism is available for the next trophic level. The remaining energy is lost as heat, used up for metabolic processes, or expelled as waste. Energy transfer efficiency depends on the energy requirements of an organism and its position in the food chain. The energy requirements of organisms at the higher trophic levels are greater than those at the lower trophic levels, but the energy transfer efficiency is lower at the higher trophic levels due to the loss of energy through the food chain.

Thus the efficiency of energy transfer in an ecosystem is usually less than 20%.

Answer:

Carbon is the most important.

Explanation:

It's the main component

The end products of digestion for carbohydrates, fats, proteins are as follows:

Carbohydrates: Glucose

Fats: Fatty acids and glycerol

Proteins: Amino acids

The digestive enzymes secreted in the saliva, stomach, duodenum, and from the pancreas and their respective substrates are as follows:

Saliva: Salivary amylase (acts on starch), lingual lipase ( acts on fats) and lysozymes (kills pathogenic particles which might have entered the oral cavity via food intake).

Stomach: Pepsin (acts on proteins) and gastric lipase (acts on triglycerides).

Duodenum: Duodenal enterokinase ( acts on trypsinogen and chymotrypsinogen) Maltase (acts on maltose), Lipase (acts on lactose) and Sucrase ( acts on sucrose).

Pancreas: Trypsinogen (inactive form of trypsin), chymotrypsinogen (inactive form of chymotrypsin), elastases (acts on elastin), Lipase ( acts on dietary fat molecules), protease (acts on dietary proteins) and pancreatic amylase (acts on starch molecules).

Salivary amylase: Digestion of carbohydrates also starts in the mouth. The amylase produced by the salivary glands, breaks down complex carbohydrates i.e, primarily cooked starch into shorter chains or even simple sugars. It's also known as ptyalin at times.

Lingual lipase: The mouth is where lipid digestion begins. Lingual lipase initiates the breakdown of lipids and fats.

Lysozyme: Because food contains microorganisms like bacteria and viruses in addition to important nutrients, it has a limited but nevertheless useful antiseptic function during digestion.

Pepsin: The primary stomach enzyme is pepsin. It is created by the principal cells of the stomach, which are zymogens that manufacture pepsinogen, an inactive form of the digestive enzyme. The stomach acid then converts pepsinogen into its active form, pepsin. Pepsin breaks down the protein in the diet into more manageable pieces like amino acids and fragments of peptides. As a result, protein digestion primarily begins in the stomach, as opposed to carbohydrate and lipid digestion, which begins in the mouth.

Gastric lipase: It is an acidic lipase that is released by the gastric main cells of the stomach's fundic mucosa. Its pH ranges from 3-6. Gastrointestinal lipase and lingual lipase are the two acidic lipases namely. These lipases do not require bile acid or colipase for effective enzymatic action, in contrast to alkaline lipases (like pancreatic lipase). Gastric lipases act on triglyceride molecules to produce fatty acids and glycerol.

Duodenal enterokinase: Trypsinogen is activated into its active i.e, trypsin by the duodenal enzyme enterokinase.

Maltase: Helps in conversion of maltose into glucose.

Lactase: Helps in breaking down of lactose into glucose and galactose.

Sucrase: Breaks down sucrose to produce glucose and fructose.

Trypsinogen: Produced as an inactive (zymogenic) protease which is turned into trypsin in the duodenum. Trypsin breaks down proteins at their fundamental amino acids. The duodenal enzyme enterokinase converts trypsinogen into its active form, trypsin.

Chymotrypsinogen: When duodenal enterokinase activates the inactive (zymogenic) protease chymotrypsinogen, it transforms into the enzyme chymotrypsin, which degrades proteins at their aromatic amino acids.

Carboxypeptidase: A protease which removes the protein's terminal amino acid group.

Elastases: Break down various proteins, including elastin.

Pancreatic lipase: Triglycerides are broken down by pancreatic lipase into two fatty acids and a monoglyceride.

Several nucleases, such as DNAase and RNAase, break down nucleic acids.

The pulmonary circulatory system goes from the heart to the lungs and back to the heart. Option B is correct.

The pulmonary circulatory system begins at the right ventricle of the heart and carries deoxygenated blood from the heart to the lungs. In the lungs, the blood releases carbon dioxide and picks up fresh oxygen, which is then transported back to the heart in the pulmonary veins.

The right ventricle then pumps the oxygenated blood into the systemic circulation to be distributed to the rest of the body. The pulmonary circulation is a shorter, more direct route than the systemic circulation and serves the important function of allowing the blood to exchange gases with the lungs.

The type of reflex arc that consists of only an afferent neuron and an efferent neuron is called a monosynaptic reflex arc. In this type of reflex arc, the sensory information is relayed directly from the afferent neuron to the efferent neuron without involving any interneurons.

To explain further, a reflex arc is the neural pathway that mediates a reflex action. It typically involves five components: a receptor, a sensory neuron (afferent neuron), an interneuron (sometimes), a motor neuron (efferent neuron), and an effector. The receptor detects a stimulus, and the sensory neuron transmits the sensory information from the receptor to the central nervous system (CNS).

In the case of a monosynaptic reflex arc, the sensory information is transmitted directly from the afferent neuron to the efferent neuron, without involving any interneurons. This direct connection allows for a quick and automatic response to the stimulus. An example of a monosynaptic reflex is the patellar reflex, where tapping the patellar tendon causes the quadriceps muscle to contract, extending the leg.

In summary, a monosynaptic reflex arc consists of only an afferent neuron and an efferent neuron. It allows for a rapid and automatic response to a stimulus without involving interneurons.
