A liger is the offspring of a male lion and a female tiger. male ligers cannot produce offspring. this is an example of
Final answer:
A liger, as the hybrid offspring of a male lion and a female tiger, is sterile, exemplifying a biological phenomenon where the mixed chromosomes from parents of two different species produce non-viable gametes.
Explanation:
The offspring of a male lion and a female tiger, known as a liger, exemplifies a phenomenon of hybrid sterility. Male ligers are unable to produce offspring. This is due to the fact that the parental species, lions and tigers, have a different number of chromosomes which, when combined, create a mismatched set. Although the ligers and tigons have a functional set of genes, the gametes produced during meiosis do not have a complete set of genes necessary for survival in subsequent generations. This biological concept is seen in other animal hybrids as well, such as mules and hennies, which are the sterile offspring of horses and donkeys. Understanding these hybridization outcomes is vital for conservation and biology.

Which system is most dependent on a normal atmospheric pressure?
Respiratory system is most dependent on a normal atmospheric pressure.
What are the functions of respiratory system?
The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system.
The respiratory system's main job is to move fresh air into your body while removing waste gases. Once in the lungs, oxygen is moved into the bloodstream and carried through your body.
The major components of the respiratory system are the bronchi, the larger conducting airways that begin at the end of the trachea and go into the lung; the bronchioles, the more narrow airways that branch from the bronch.

Based on the table, which domains contain only one cell type? Fungi and Eukarya Bacteria and Archaea Eukarya and Fungi Plantae and Bacteria
The right answer is Bacteria and Archaea.
A prokaryote is a unicellular organism (bacterium, cyanophyceae) that does not have a nucleus. The DNA is circular, usually unique and grouped in a nucleoid. This region contains the genetic material, but is not separated from the rest of the cell. This is precisely what separates the prokaryote from the eukaryote.
Archaea are prokaryotic unicellular microorganisms. Archaea, which often look like bacteria, have long been regarded as specific extremophile bacteria, until phylogenetic research on prokaryotes, begun in 19652, culminated in the publication in 1977 of a phylogenetic tree based on the sequences of the ribosomal RNA genes of the organisms studied, a tree in which the prokaryotes were split into two distinct domains, that of the bacteria and that of the archaea.
The domains that contain only one cell type are Bacteria and Archaea as all organisms within these domains are unicellular.
Explanation:In the context of biological classification, cell type is one way to categorize living organisms. The question refers to 'domains', one of the highest taxonomic ranks in this system. In terms of cell type, all organisms in the domains Bacteria and Archaea are unicellular, meaning they only have one cell type. However, other domains like Eukarya include both unicellular organisms (like some fungi and protists) and multicellular organisms (including animals, plants, and most fungi).

Various enzymes function most efficiently under different sets of “optimal” conditions. explain why this is the case.
Enzymes work efficiently under specific conditions due to their adaptation to different cellular environments and factors like pH and temperature. Variations in enzyme activity depend on environmental factors and substrate concentration. These factors ensure optimal biochemical reactions in cells.
Enzymes are biological catalysts that function most efficiently under specific optimal conditions. Several factors contribute to this phenomenon:
Enzymes are adapted to their cellular environments, so different cells have varying enzyme needs. For example, stomach cells require different enzymes compared to fat storage cells or nerve cells.Environmental factors like pH, temperature, and salt concentration significantly impact enzyme activity. For instance, human pathogens have enzymes that work best at 37°C, while microbes in hot springs have enzymes optimized for high temperatures.The presence of dietary intake influences enzyme activity in digestive organs, where more enzymes are needed to process nutrients after a meal.Enzyme activity is also influenced by substrate concentration. Increased substrate levels enhance enzyme activity up to a saturation point.These conditions ensure that enzymes efficiently catalyze reactions necessary for cellular functions to adapt to their varying environmental and physiological requirements.

B. They are red in color.
C. They form in the wet tropics.
D. They are very productive agriculturally.
Please explain your answer! :)
Answer:
D. They are very productive agriculturally.
Explanation:
Laterite soils are of rusty red color. Their red appearance is because of the fact that they have very high content of iron and iron oxide. They are formed in wet tropics naturally. They are not at all suitable for agriculture because they are highly acidic in nature. Not only this but also, they have very low water retention capacity. These two properties make them unsuitable for cultivation.
