Explanation:

All five domains are related to sustainable development because they are the 5 domains of sustainability.

Sustainability has always been portrayed as having three domains: the environment, economics, and the socio-cultural milieu, and they must be managed interdependently for a sustainable balance to occur (i.e., the Bruntland Commission of the United Nations, 1987). Many business and political leaders have expressed skepticism about equating another field with economics.

Even those who will adopt the ideals of living in harmony with nature frequently discover that the instruments available in these three spheres are inadequate. Thus, the environment, social, technological, economic, and public policy are the suggested Five Domains of Sustainability. Additionally, these domains ought to serve as the organizing principles for regional and urban sustainable development, urban growth management, and urban administration.

This is a perfect example of artificial intelligence and machine learning.

What is artificial intelligence?

Artificial Intelligence (AI) is intelligence exhibited by machines, as opposed to natural intelligence demonstrated by animals and humans. Artificial intelligence research is described as the study of intelligent agents, which refers to any system that observes its surroundings and performs actions that optimize its chances of success.

The following are some similarities between living and nonliving objects: both living and nonliving things have mass.

They both take up a considerable amount of room.

They are both made up of fundamental components (cells for living, particles for nonliving things).

Both may be transported at the expense of energy.

A student has a pure culture of bacteria growing in a flask and wants to know how many living cells are in the culture at a given time. Plate counting is the method should she employ to get an estimate.

It is a technique to determine the number of living cells in a sample using different steps.

The sample (1g)  is first diluted with a suitable diluent (9g) and then mixed together. This solution is then added to another (9g) diluent. It is repeated to get a number of series.

The sample is then plated on an agar plate. These plates are then moved to an incubator at a suitable growth temperature.

We then calculate the plates having colonies between 50-300. Now we have to calculate the number of organisms that were in the original sample.

The endocrine glands secrete their products into intracellular spaces and the exocrine glands secrete their products into ducts/surface

Endocrine glands are network of various glands in your body that produce and secrete chemicals known as hormones. They are ductless glands. Therefore, the hormones that are produced by them would be secreted directly into the intracellular spaces which would diffuse into the bloodstream and reach the cells in the body.

The glands in various location in human body that are responsible for the production of hormones are Pituitary, Pineal, Pancreas, Hypothalamus, Thyroid, Adrenal, Testes and ovaries.

Exocrine glands are network of glands that secrete the compounds produced by them into ducts. These ducts carry the products to the surface and release them. Sweat glands, Salivary glands, sebaceous glands, Lacrimal glands are some of the exocrine glands.

Answer:

neighbouring healthy cells will die when molecules activate death cascades because the death molecule passes through gap junctions.

Answer: adenine pairs with thymine, cytosine pairs with guanine

Explanation:

the nitrogenous bases are adenine, thymine, guanine and cytosine.the pairing occurs because the complementary bases form hydrogen bonds with each other.

Explanation:

The nitrogen bases form the double strand of DNA through weak hydrogen bonds. The nitrogen bases, however, have specific shapes and hydrogen bond properties so that guanine and cytosine only bond with each other, while adenine and thymine also bond exclusively.

The NADH transfer the electron to the first complex1.The electron then move through a series of iron sulphur protein and reducing it to QH2 called as quinol.

An electron is a negative charges subatomic particle that can exist either free or bonded to an atomic (not bound).. One of the three main types of particles within an atom is an electron that is bonded to it; the other two are protons and neutrons.

The number of electron shells is equivalent to the atomic quantity of an element for neutrally charged species. This shows that an element's protons and electrons are distributed equally.. Consequently, there are 8 electrons in oxygen.

The organisms belonging to the same order will share more structural similarities than the organisms belonging to the same class. It is because order is a lower group in taxonomic classification.

Taxonomy is the systematic and scientific approach of grouping things based on their similarities. Taxonomy provides hierarchical classification of the things.

Taxonomy contains seven basic elements in which the organisms are grouped into. Species form the unit level of taxonomy. Genus, family, order, class, phylum and kingdom of an organism is included. Kingdom is considered as a superior and diverse group of taxonomy.

Thus, taxonomy is an effective way of representing diverse information of organisms in an organized way.

The Kreb's cycle produces ATP, NADH, FADH₂ and releases CO₂, which contains the carbon atoms remaining from the original 6-carbon glucose molecule.  

The Kreb's cycle, also called the citric acid cycle, or TCA (Tricarboxylic acid) cycle is a series of reactions that are catalysed by enzymes and occur in the matrix of the mitochondria. In the reaction, acetyl-CoA, the end product of glycolysis gets oxidized and produces ATP, high energy compounds - NADH and releases CO₂ as a by-product.

The Krebs cycle is the second stage of cellular respiration. The first stage of cellular respiration is glycolysis, which occurs in the cytosol of the cell. In glycolysis, one glucose molecule undergoes partial oxidation to give two pyruvate molecules. The pyruvate molecules undergo further oxidation in the matrix of the mitochondria to produce acetyl-CoA. Here, glycolysis ends, and the Krebs cycle begins.

The two molecules of acetyl-CoA formed from the pyruvate molecules then enter the Kreb's cycle. Acetyl-CoA is combined with oxaloacetate, a four-carbon compound, and produces ATP, NADH, FADH₂ and 2 molecules of CO₂ as by-product.

Yes, the blood become more acidic during the heavy exercise because of the production of CO2 in the body.

Acidic Blood- Exercise that is vigorous will drop blood pH and increase blood acidity. This happens because during intense activity, muscle cells are compelled to engage in anaerobic respiration. Lactic acid is a byproduct of this kind of cellular respiration. The blood's pH level will decrease in the influence of this acid.

Anaerobic respiration- It's a process that happens without any oxygen gas. In this mechanism, glucose is broken down to provide energy without the need of oxygen. The fermentation of yeast is among the greatest illustrations of anaerobic respiration.

Answer:

1. telescope

2. astronomers

3. radio waves

Explanation:

A telescope allows one to magnify what they're looking at to see it closer than it actually is. Astronomers are those that study planets, stars, and other celestial bodies in space. Modern telescopes have the ability to detect radio waves from astronomical objects that emit them from far away.  This allows us to see what we normally would not be able to.

Scientist Galileo Galilei used the telescope to observe the stars and planets. This same tool has allowed modern astronomers to see objects that are billions of light years from Earth. This tool also detects things such as gamma rays and x-rays, which are invisible to the human eye.

Galileo observed the night sky and made several revolutionary findings, such as the discovery of the four largest moons of Jupiter, the phases of Venus, and the craters and mountains on the Moon. These observations provided compelling evidence for the heliocentric model of the solar system proposed by Copernicus, where the Sun is at the center, and the planets, including Earth, revolve around it.

Galileo's use of the telescope marked a pivotal moment in the history of astronomy, as it allowed scientists to explore the cosmos in unprecedented ways. Fast forward to modern times, and telescopes have undergone significant advancements and technological improvements. Modern astronomers now have access to powerful telescopes, including space-based telescopes like the Hubble Space Telescope, which can observe objects that are billions of light-years away from Earth. These telescopes have provided stunning images and data of distant galaxies, nebulae, and other celestial phenomena, shedding light on the vastness and complexity of the universe.
