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.

Immunity how does our immune system protect us from disease pogil answers
Our immune system protects us from foreign and damaging organisms through our antigens. Once a pathogen (damaging cells/harmful) is detected within the body, the immune system deploys white blood cells to defend the host and eliminate the threat. The Immune System acts as our body’s security system.
The immune system is a complex network of cells, tissues, and organs that work together to protect the body from harmful pathogens. It includes key components such as white blood cells, antibodies, and the complement system.
Explanation:The immune system is a complex network of cells, tissues, and organs that work together to protect the body from harmful pathogens, such as bacteria, viruses, and parasites. its components are -
White blood cells: These cells are the main players in the immune system. They include neutrophils, macrophages, and lymphocytes.Antibodies: Antibodies are proteins produced by B cells and play a critical role in identifying and neutralizing harmful pathogens.Complement system: The complement system is a group of proteins that work together to enhance the immune response.The immune system has two main phases: the innate immune response and the adaptive immune response. The innate immune response is the first line of defense and provides immediate, nonspecific protection. It includes physical barriers (e.g., skin), chemical barriers (e.g., stomach acid), and certain white blood cells. The adaptive immune response is specific to a particular pathogen and develops over time. It involves the production of antibodies and memory cells that provide long-term immunity. Our immune system is crucial for protecting us from diseases. It employs a network of cells, tissues, and organs to identify and eliminate harmful pathogens. Understanding how our immune system works can help us make informed choices to stay healthy.

What is the result of meiosis II?
two diploid daughter cells
four haploid daughter cells
two haploid daughter cells
four diploid daughter cells
Answer: Option B
Explanation:
In some species there is a very small interphase, or interkinesis before the cell enters in the the process of meiosis II.
The two daughter cells that are produced after meiosis I go though the process of meiosis II. During the process of meiosis II the two sister chromatids which lies in daughter cells separate, resulting in formation of four haploid daughter cells. This process is similar to mitosis.

_____ is a process that helps fuel your metabolism.
Deoxidation
Oxidation
Glycolysis
Hydrolysis
The correct option is B. Oxidation is a process that helps fuel your metabolism.
Oxidation is a metabolic process where nutrients like carbohydrates, fats, and proteins are broken down to release energy in the form of ATP through reactions involving oxygen.
This process fuels metabolism by transferring electrons from these nutrients to oxygen, generating ATP in cellular respiration.
The other options are incorrect because:
A. Deoxidation is not a metabolic process; refers to removal of oxygen.C. Glycolysis is an initial breakdown of glucose, not directly fueling metabolism.D. Hydrolysis is breakdown of molecules by water, not directly related to metabolic fueling.The correct question is:
_____ is a process that helps fuel your metabolism.
A. Deoxidation
B. Oxidation
C. Glycolysis
D. Hydrolysis
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).

Which is not true of laterite soils?
A. They are enriched in iron oxide.
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.
