differentiate between natural resources and water resources
Answer:
Explanation:
Water resources are natural resources of water that are potentially useful for humans, for example as a source of drinking water supply or irrigation water. 97% of the water on the Earth is salt water and only three percent is fresh water; slightly over two thirds of this is frozen in glaciers and polar ice caps where as Natural resources are resources that are drawn from nature and used with few modifications. This includes the sources of valued characteristics such as commercial and industrial use, aesthetic value, scientific interest and cultural value
What is the role of alveoli in respiration
Answer:
What is the role of alveoli in respiration ⇔ Alveoli are the place where the exchange of gases takes place. The outer part of alveoli has blood vessels. These vessels are carrying Co2 rich blood to exchange at the alveoli. The O2 from the alveoli is diffused into the blood while co2 is sent into the lungs. That O2 rich blood is then carried to heart to pump it to the whole body. and this process continues. The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out.

The most significant benefit of replacing human labor with automated labor is?
The most significant benefit of replacing human labor with automated labor is lowered wages and benefit costs.
Since automation is the foundation of the present economy, it makes sense to infer that automation will also shape the future. There seems to be a new research or opinion piece about the potential for robots and artificial intelligence to eliminate jobs every week.
Robotic machines perform repeated jobs that soon grow monotonous for people, which lowers errors.Robots are more accurate and can do tasks more quickly than humans labor.
Robots reduce expenses since they can operate continuously with the right maintenance and don't need all the added advantages that people do, such as healthcare, paid time off, sick days, and breaks.

For this discussion, please create two questions about homeostasis and the relationships between the immune, endocrine, and nervous systems. Your questions should address how the actions of one system are balanced by another, and vice versa. For example, do you think the eye reflex to make tears (nervous system) would be necessary if the immune response to substances on the eye were stronger? Or if our endocrine system raised our body temperature two degrees, would our immune system become weaker because using a fever to fight infection would be less necessary?
Two questions about homeostasis may be how endocrine signaling may affect the immune responses and how the nervous system work together with the endocrine signaling.
What are endocrine signals?Endocrine signals are different molecules called hormones that are released by specialized cell types and travel to the bloodstream to carry out functions in the body.
Endocrine signaling affects immune responses (e.g., inflammation) and both neural and endocrine signaling may affect different types of homeostatic responses.

A connection among creatures called commensalism occurs when one species advantages while the other remains undisturbed. A range of commensal microorganisms that live in animals' tissues but are not harmful to them is necessary for their existence.The commensal, or individual that gains from the connection, could take resources from the host organism, which is generally unharmed or get refuge from it, sustain it, or use it for movement. A bigger host and a smaller commensal are frequently in a commensal relationship; the host species remains unaltered, whilst the commensal individual could exhibit substantial design adaptations commensurate with its lifestyle, as in the case of remoras that travel connected to shark species as well as other fishes. Pilot fish eat the leftovers from their hosts' meals, but remoras consume their hosts' feces.

Changing the strength of connections between neurons is essential for the brain's capacity to store and process information. For less than a second, presynaptic facilitation, a type of short-term plasticity, improves synaptic transmission. Presynaptic facilitation is a pervasive phenomena that is regarded to be essential for the flow of information and brain processing. However, a major portion of our knowledge about facilitation's role is still theoretical. Here, we review the suggested functions of presynaptic facilitation and talk about how recent advances in understanding the underlying molecular mechanisms may make it possible to conduct experiments that clarify the roles that facilitation—and short-term plasticity in general—play in circuit function and animal behavior.

What types of microorganisms are known as obligate intracellular parasites, meaning that they can live and multiply only inside an appropriate host cell?
Viruses are obligate parasites.
Why are viruses known as obligate parasites?A parasite is considered to be obligatory if it entirely relies on its host for habitat, sustenance, reproduction, and survival. It will eventually perish without the host. An organism that cannot reproduce without a host is said to be obligately parasitic. Holoparasite is another name for the obligatory parasite. Obligatory parasites include viruses. They are unable to procreate outside of live cells. They are hence regarded as obligatory intracellular parasites.
They infect a host cell to utilize its genetic resources for reproduction, protein synthesis, and energy production. The virus cannot thrive on culture media that is not alive. It needs functioning cells to maintain its metabolism and grow. It multiplies by independently forming each of its components using host machinery, then putting those components together to create viral particles. A virus is not irritable or mobile.

The process by which a cell copies its dna in preparation for cell division is called?
DNA replication is the process by which a cell copies its DNA in preparation for cell division.
The biological process of creating two identical copies of DNA from a single original DNA molecule is known as DNA replication. All living things replicate their DNA, which is the primary mechanism for biological heredity. Semi-conservative, conservative, and dispersive replication models were proposed as possible mechanisms for organisms to repeat their DNA.
A second double strand that is exactly the same as the first is created during replication. The first step in DNA replication is to separate the dsDNA since each of the two strands in the dsDNA molecule functions as a template for a new DNA strand. A DNA helicase accomplishes this. It is crucial that each daughter cell receives an exact copy of the DNA when a cell divides. DNA replication is the process that makes this happen. Before the cell reaches mitosis or meiosis, during the synthesis phase, also known as the S phase, of the cell cycle, DNA replication takes place.

What enzyme allows h ions to diffuse back across the membrane down their concentration gradient? this process releases energy, what is this energy used for? ATP Synthase. This proton gradient (gradient of H+) flowing through the membrane enzyme complex ATP synthetase is the direct energy source for producing ATP.
What is ATP synthase?
Adenosine diphosphate (ADP) and inorganic phosphate are used to create the energy storage molecule adenosine triphosphate (ATP) by a protein called ATP synthase . It is categorized as a ligase since it modifies ADP by forming a P-O link (phosphodiester bond). A molecular device called ATP synthase. The overall reaction that ATP synthase catalyzes is:
ATP + H2O + 2H+in ADP + Pi + 2H+out
Energy-wise, the production of ATP from ADP and Pi is undesirable, and the process would typically go the other way. A proton (H+) concentration gradient across the inner mitochondrial membrane in eukaryotes or the plasma membrane in bacteria drives this reaction forward by coupling ATP synthesis during cellular respiration to the gradient.
