It is possible to tell whether a remark affects a macroeconomic or microeconomic issue by looking at the following:

1. When Mika bargains for capital equipment for her company, a micro-economic issue is at play.

The fact that inflation has an impact on the entire economy makes it a macroeconomic problem.

3. A macroeconomic issue is the declining unemployment rate.

4. When Value Petrol cuts gasoline prices aggressively, it is a microeconomic problem.

Microeconomics is a subfield of economics that focuses on how people and businesses allocate resources and react to various economic factors like price, resource availability, and competitive pressures.

Inflation, unemployment, GDP, and growth rate are all studied as aggregates in macroeconomics. Without focusing on the choices made by specific actors, it encompasses the entire economy.

Inquiry differs from the scientific method in the following ways:

Inquiry is a mere search for information or fact while scientific method is a procedural method of discovering information.

The scientific method is a method of discovering knowledge about the natural world based on hypotheses, testing them empirically, and developing theories that match known data from repeatable physical experimentation.

Inquiry refers to a search for truth, information, or knowledge or the examination of facts or principles. It can also be termed as an investigation.

The ultimate acid-base regulatory organs in the human body are the kidneys.

The kidneys are responsible for regulating the acid-base balance of the body by selectively retaining or excreting ions such as hydrogen, bicarbonate, sodium, and potassium.

This regulation occurs in the renal tubules of the nephrons, which are the functional units of the kidneys. The kidneys work in tandem with the respiratory system to maintain acid-base balance.

The lungs regulate the amount of carbon dioxide (CO₂) in the body, which can affect the pH of the blood. When CO₂ levels increase, the blood becomes more acidic, and when CO₂ levels decrease, the blood becomes more basic.

The kidneys help to compensate for any changes in pH that result from changes in CO₂ levels by excreting or retaining bicarbonate ions.

The researchers at NREL examined solar thermochemical hydrogen photosynthesis, a new approach for water splitting that may be more energy-efficient than the more traditional electrolysis method.

Water must be electrolyzed in order to be split into oxygen and hydrogen. Plants use sunlight during photosynthesis to split water into oxygen and hydrogen, which they subsequently combine with atmospheric carbon dioxide to produce carbohydrates. Three fundamental processes—autothermal reforming, partial oxidation, and steam reforming—can be used to create hydrogen gas from hydrocarbon fuels. Hydrogen ions play a crucial role in plant respiration as well as in assisting proton gradients that power the chain of electron transport during photosynthesis. In order to assemble sugars as well as other molecules to create glucose, which is used by plants as energy, hydrogen is required.

The eukaryotic cell-cycle event that is missing in binary fission is mitosis.

Binary fission is a cell division process commonly observed in prokaryotes, such as bacteria.

It involves the replication of the genetic material followed by the division of the cell into two identical daughter cells. However, unlike eukaryotic cells, prokaryotes do not undergo mitosis, which is the process of nuclear division in eukaryotes.

Mitosis is a complex series of events that ensures the accurate distribution of replicated chromosomes into two daughter nuclei. It consists of several phases, including prophase, metaphase, anaphase, and telophase, which result in the formation of two genetically identical daughter cells. Therefore, mitosis is the eukaryotic cell-cycle event that is absent in binary fission.

The elements heavier than hydrogen and helium were created by nucleosynthesis in massive stars.

Hence Option (b) is correct.

Stellar nucleosynthesis, the process by which stars combine lighter elements with heavier ones in their centers, releases energy.

Many of the lighter elements, up to and including iron and nickel, are produced by nuclear fusion processes in the most massive stars.

Fusion, also referred to as "nuclear burning," is the conversion of lighter elements into heavier ones to produce the energy that powers a star.

Most elements heavier than helium in the cosmos are thought to have formed in stars when lighter nuclei fused to form heavier nuclei.

That is how nucleosynthesis, which occurs in large stars, produces the elements heavier than hydrogen and helium.

C. Photosynthesis and cellular respiration

Explanation:

Photosynthesis uses energy from the sun, carbon dioxide, and water, to produce glucose and oxygen. This is used as a food source in plants.

Glucose is broken down by cellular respiration to release energy in the form of ATP.

Cellular respiration breaks down glucose in the presence of oxygen to produce energy, releasing water and carbon dioxide.

Speciation events can be caused by prezygotic barriers that prevent populations of organisms from mating with one another. This assertion is accurate.

Reproductive isolation is the condition in which biological barriers prevent members of two species from interbreeding. Prezygotic barriers: prevent ova from fertilizing if members of different species try to mate, or prevent mating across species.

Hybrids are more likely to form in populations divided by physical barriers that cause speciation because people cannot physically interact with one another. The hybridization zone is a region of habitat where this kind of interaction and mating frequently takes place.

Answer:

Prokaryotes are smaller and less developed compared to eukaryotes. Some of them inhabit very primitive environments that resemble earth’s early stages. Endosymbiotic theory states that eukaryotes arose by the endosymbiosis of prokaryotes.

Explanation

By endosymbiont theory, eukaryotic cells arise from prokaryotic cells. Here, the theory shows that eukaryotic ancestors lived in close association with prokaryotes, wherein in some cases, prokaryotes have been engulfed and might have lived inside eukaryotes.

Upon being engulfed by a host cell as undigested prey, these prokaryotes could have been internal parasites of the eukaryotes. But, later on, their relationship becomes mutualistic and these prokaryotes become incorporated as organelles, such as in the case of chloroplasts and mitochondria, which were previously separate prokaryotes

______________________________________

Prokaryotic cells probably appeared before eukaryotic cells​ because they are less complex.

Evolution means descendence with modification, which can be defined as a consequence of natural selection.
