Answer:

Carbondioxide, water and urea are the waste product.

Explanation:

The final waste product produced by the organisms during respiration are carbondioxide and water while urea and nitrogenous waste are also a waste product produced in the body when the digestion of food is completed. The unnecessary substances present in the food are removed and sent it to excretory organ. These waste products are removed from lungs and urinary bladder.

The type of pathogen that contains a nucleus is eukaryotic pathogen. A pathogen is defined as an organism that causes infection or disease.

Pathogens are biological agents that cause illness in humans, animals, or plants. Pathogens can be bacteria, viruses, fungi, protozoa, or parasites. A pathogen is said to be eukaryotic if it contains a nucleus. The nucleus in eukaryotic cells is bound by a double membrane that separates DNA from the cytoplasm. All multicellular organisms are eukaryotic, whereas prokaryotic organisms are unicellular. Prokaryotic cells do not have a true nucleus, and their genetic material is dispersed throughout the cytoplasm. Eukaryotic pathogens, as the name suggests, are pathogens that have eukaryotic cells. Fungi, protozoa, and some parasites are examples of eukaryotic pathogens. Viruses, bacteria, and some parasites are examples of prokaryotic pathogens.

Answer:

There are 10 males and 15 males under the age if two.

Answer: First awnser

Explanation:

1A. Out of the given sentences, option B "Amphibians have scaly skin" is not a characteristic feature of amphibians.

1C. Metamorphosis is a process of complete transformation in an organism's body structure and function. For example, during frog metamorphosis, a tadpole undergoes changes such as growing limbs, developing lungs, and absorbing its tail. These changes enable the tadpole to transition into a fully formed frog capable of living on land.

1A. Amphibians do not have scaly skin like reptiles. Instead, they have thin, moist skin that allows for gas exchange through their skin.

This characteristic enables them to respire both in water and on land. The moisture on their skin helps them to absorb oxygen directly from the environment. Therefore, the correct answer is B.

1C. Metamorphosis is a biological process through which an organism undergoes a remarkable change in its body structure and physiology during its life cycle. One example of metamorphosis is seen in the life cycle of a butterfly.

During metamorphosis in butterflies, the process begins with an egg. From the egg, a larva, known as a caterpillar, hatches. The caterpillar goes through a feeding stage, where it consumes a significant amount of food to fuel its growth. It molts several times, shedding its outer skin as it grows.

After reaching a certain stage of growth, the caterpillar forms a protective covering called a chrysalis or pupa. Inside the chrysalis, the caterpillar undergoes a complete transformation. Its body undergoes extensive restructuring, and tissues, organs, and appendages are broken down and reorganized. This process is called metamorphosis.

Finally, after a period of time, the adult butterfly emerges from the chrysalis. It has fully developed wings, and a different body shape, and is capable of reproducing. The transformation from a crawling caterpillar to a flying butterfly is a remarkable example of metamorphosis.

The correct sequence of renal tubule segments through which filtrate would flow is B. proximal tubule, descending limb of nephron loop, ascending limb of nephron loop, distal tubule.

The kidney consists of three primary sections: renal cortex, renal medulla, and renal pelvis, the renal tubule is a portion of the nephron that carries a filtrate away from the glomerulus. Each nephron in the kidney has a renal tubule, which is divided into four different regions. The four regions are the proximal convoluted tubule, the loop of Henle, the distal convoluted tubule, and the collecting duct. The proximal tubule is the segment of the renal tubule that immediately follows Bowman’s capsule and is responsible for most of the reabsorption of nutrients and ions from the glomerular filtrate.

The descending limb of the loop of Henle is the second segment of the renal tubule, which is responsible for reabsorbing water. The third segment of the renal tubule is the ascending limb of the loop of Henle, which is responsible for reabsorbing ions, particularly Na⁺ and Cl⁻. The final segment of the renal tubule is the distal tubule, which is responsible for reabsorbing additional ions and regulating the pH of the urine. So therefore the correct answer is B. proximal tubule, descending limb of nephron loop, ascending limb of nephron loop, distal tubule.

The filtrate in the renal tubule flows in the sequence: Proximal tubule, descending limb of nephron loop, ascending limb of nephron loop, and distal tubule, finally reaching the collecting duct where it gets converted into urine. These segments allow the reabsorption of water and useful substances, along with the expulsion of waste substances.

The correct sequence of renal tubule segments in which filtrate would flow in the human body is: Proximal tubule, descending limb of nephron loop, ascending limb of nephron loop, distal tubule, and then the collecting duct. Kidney filtration starts at the Bowman's capsule which then passes it to the proximal tubule, the descending and ascending limbs of the nephron loop (Loop of Henle), followed by the distal tubule, and finally the collecting duct where it is converted into urine. The filtrate moves through these consecutive segments in order, a process which allows the body to reabsorb water and various useful substances while expelling waste substances as urine.

In living cells, complex metabolic reactions proceed in a series of steps called metabolic pathways.

Metabolic pathways are a series of interconnected chemical reactions that occur within living cells. These pathways are responsible for the breakdown, synthesis, and transformation of molecules necessary for various cellular processes. Each step in a metabolic pathway is catalyzed by a specific enzyme, which acts as a biological catalyst to facilitate the reaction.

Metabolic pathways are highly organized and regulated to ensure efficient utilization of resources and maintain cellular homeostasis. They involve a variety of biochemical reactions, such as oxidation, reduction, phosphorylation, and decarboxylation, among others. These reactions often involve intermediate compounds that are sequentially transformed through the action of specific enzymes.

Metabolic pathways can be linear, branching, or cyclical, depending on the specific process and requirements of the cell. Examples of well-known metabolic pathways include glycolysis, the citric acid cycle (Krebs cycle), and the electron transport chain, which are crucial for energy production in cells.

Overall, metabolic pathways allow living cells to efficiently process and utilize nutrients, generate energy, synthesize complex molecules, and maintain essential cellular functions. By breaking down complex metabolic processes into smaller steps, cells can regulate and control these reactions to meet their metabolic needs.

The closure of a plant's stomata will retain water when the plant becomes dehydrated and wilts.

Two guard cells surround each stoma, a small pore or hole, and they expand and contract to close and open the stoma. The carbon dioxide content and the plant's water balance act as two controls on the opening and shutting of the stomata.

Guard cells inflate and bend as a result of water entering them through osmotic movement. The holes are opened by the guard cells expanding. Through open stomata, the plant absorbs carbon dioxide for use in photosynthesis. Through open stomata, oxygen and water vapor are also expelled back into the atmosphere.
