Explanation:

kidneys are used to filter blood..... removal of water, urea and excess salts

The role of the liver in waste removal is to filter urea out of the blood and into the bladder. Thus, option A is correct.

The liver is a very important organ of human body and the weight of liver is 1.5 kg and width of liver is 15 cm. The colour of liver is reddish - brown.

The main functions of liver are it carries out the function of protein's metabolism and it excretes bile and it is also responsible for excreting cholesterol, hormones, bilirubin and drugs.

The liver also stores vitamins, glycogen, and minerals so it the center of storage also.

As liver is a very important organ so to maintain it's health a person have to maintain a healthy weight, take a balanced diet, regular exercise, avoiding toxins, and  less use of alcohol leads to keep the liver safe and healthy.

Therefore, the role of the liver in waste removal is to filter urea out of the blood and into the bladder. Thus, option A is correct.

According to the question, approximately 2192.5 joules of energy are required to freeze 5 grams of water.

The formula for determining the energy is as follows:

where Q is the heat energy required, m is the mass of the water which is 5g, C is the specific heat capacity of water which is 4.18 J/g/°C and ΔT is the change in temperature.    

Now,  Q = 5 × 4.18 × 25

              = 522.5 J.

Now, we require to determine how much heat energy is required to freeze the water. This can be calculated using the formula:

Q = m × Hf

where Q is the heat energy required, m is the mass of the water, and Hf is the heat of the fusion of water.

Q = 5 g * 334 J/g

Q2 = 1670 J

Now, to find the total amount of energy which is required to freeze 5 grams of water:

522.5 J + 1670 J = 2192.5 J.

Therefore, approximately 2193.5 joules of energy are required to freeze 5 grams of water.

When you swallow, peristaltic muscular contractions transfer food from your mouth into your stomach. Here option C is the correct answer.

When you swallow food, the process involves a coordinated effort of several mechanisms to move the food from your mouth to your stomach. The primary mechanism responsible for this movement is peristaltic muscle contractions.

Peristalsis refers to the rhythmic contraction and relaxation of muscles in a wave-like motion. In the case of swallowing, peristalsis occurs in the esophagus, a muscular tube connecting the mouth to the stomach. As you initiate the swallowing reflex, the food bolus is propelled through the esophagus by sequential waves of muscular contractions. These contractions squeeze the walls of the esophagus, pushing the food forward in a coordinated manner.

The pressure difference between different zones of the esophagus also plays a role in facilitating the movement of food. When you swallow, the upper esophageal sphincter relaxes, allowing the food to enter the esophagus. Subsequently, the lower esophageal sphincter relaxes, allowing the food to enter the stomach. These sphincters help maintain pressure differences between the different regions, ensuring the unidirectional flow of food.

Answer:

Explanation:

The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.

Prokaryotes only contain a single circular chromosome and lack a nucleus and membrane-bound organelles. In contrast, eukaryotes have numerous linear chromosomes and a nucleus.

Organisms called eukaryotes have intricate cellular structures. Their cells are distinguished by the presence of a genuine nucleus, which contains the DNA that serves as the genetic code. The nuclear envelope, a double membrane that encloses the nucleus, is made up of numerous organelles including the Golgi apparatus, endoplasmic reticulum, and mitochondria. These organelles are in charge of carrying out numerous metabolic processes and carrying out specialised tasks required for the survival of the cell. On the other hand, prokaryotes are straightforward organisms devoid of a nucleus and organelles that are bound to membranes. Their cells have a single nucleoid, a circular fragment of DNA that floats freely in the cytoplasm and gives them some control over their genetic makeup.

At the end of glycolysis, the potential/chemical energy released from glucose is now stored in (A) NADH and ATP.

Glycolysis is the initial step in glucose metabolism and occurs in the cytoplasm of cells. During glycolysis, glucose is converted into pyruvate through a series of enzymatic reactions. Along the way, energy is released and captured in the form of ATP and NADH.

ATP (adenosine triphosphate) is a high-energy molecule that serves as the primary energy currency of cells. NADH (nicotinamide adenine dinucleotide) is an electron carrier that carries high-energy electrons to the electron transport chain, where they can be used to generate additional ATP through oxidative phosphorylation.

These stored energy molecules, ATP and NADH, can then be utilized by the cell to carry out various cellular processes and functions. Nucleotides, amino sugars, and light are not directly involved in storing the energy released from glucose during glycolysis.

The correct answer is (b) Hydrophobic hormones are transported in the blood by binding to hydrophilic transport proteins.

Hydrophobic hormones, such as steroid hormones (e.g., cortisol, estrogen, testosterone) and thyroid hormones (e.g., thyroxine, triiodothyronine), are lipophilic or lipid-soluble in nature. Being hydrophobic, these hormones do not readily dissolve in the watery environment of the bloodstream. To overcome this challenge, they require transport proteins for efficient transportation through the blood.

Transport proteins, known as carrier proteins or binding proteins, are produced by the liver and are specialized to bind with hydrophobic hormones. These proteins have hydrophilic regions that can interact with the aqueous environment of the blood while simultaneously binding to hydrophobic hormones. By forming complexes with transport proteins, hydrophobic hormones become soluble in the blood and can be effectively transported to their target tissues.

Once the hormone reaches its target tissue, it dissociates from the transport protein and interacts with intracellular receptors to exert its biological effects. The binding of the hormone to its receptor initiates a cascade of cellular events that regulate gene expression and other physiological processes.

It's important to note that hydrophilic hormones, on the other hand, can readily dissolve in the watery environment of the blood and do not require transport proteins for their transportation. They can freely circulate in the bloodstream in their soluble form.

Therefore, hydrophobic hormones are transported in the blood by binding to hydrophilic transport proteins, allowing them to be efficiently delivered to their target tissues.

Examine five words and/or phrases and determine the relationship between most of the words/words. Here the upwelling does not fit the pattern. Here option E is the correct answer.

The majority of the words/phrases are related to the factors that can affect the rate of photosynthesis in plants. Photosynthesis is the process by which plants convert light energy into chemical energy, using carbon dioxide and water to produce glucose and oxygen.

Lower rates of photosynthesis indicate a decrease in the amount of light energy that is converted into chemical energy. This can be caused by various factors, including insufficient light, water, or nutrients. Increased phosphorus concentration, high light levels, and increased nitrogen concentration, on the other hand, are all factors that can increase the rate of photosynthesis by providing the necessary nutrients and energy for the process.

Upwelling, however, does not fit this pattern as it is not a direct factor that affects photosynthesis in terrestrial plants. Upwelling refers to the movement of cold, nutrient-rich water from the bottom of the ocean to the surface, which can provide nutrients for marine plants. However, terrestrial plants do not directly benefit from this process as they do not have access to nutrient-rich water.
