The Monera Kingdom has many kinds of organisms is True.
Unicellular and colonial creatures, such as cyanobacteria and the true bacteria (eubacteria), comprise the kingdom Monera, which contains 10,000 species (blue-green algae).
Members of the Kingdom Monera family are prokaryotes. None of the species that make up this kingdom have a true nucleus. These are the oldest known bacteria on Earth. DNA is not found in their nucleus.
The monerans are unicellular organisms. They include 70S ribosomes. The exposed DNA is not protected by a nuclear membrane. The centrosome, lysosomes, plastids, Golgi bodies, mitochondria, and other organelles are absent. They procreate sexually through a binary fission or budding process.

"Energy saving can be known as energy production". Justify the statement.
Answer: Energy saving can help produce more energy. Increases food and item production.
Explanation:
Which statement is NOT true about subatomic particles? a) In chemical reaction the number of protons change. b) Neutrons have no electrical charge. c). Electrons in the outer orbit determine the chemical reactivity of the atom d) Electrons are found in orbitals outside of the nucleus. e) Protons are found in the nucleus.
The statement which is not true about subatomic particles is: (a) In chemical reaction the number of protons change.
Subatomic particles are the materials that make up an atom. They are smaller in size than the atom. There are three sub-atomic particles: protons, neutrons and electrons. The proton and neutron make up the nucleus of the atom, and the electrons reside in a cloud form surrounding the nucleus.
Protons are the positively charge sub-atomic particles. Since they form the core (nucleus) of the atom therefore they cannot take part in any chemical reaction and hence their number never changes. If the number of protons change then the identity of the atom will also change.

An organism's home is known as its habitat, and its function in its environment is known as its niche. While niche focuses on how the creature effects the environment, habitat focuses on how the environment impacts the organism.
What about species?A group of things that share the same kind and name: kind. A group of related organisms with the capacity to bear viable offspring that falls below the genus level and is designated by a two-part scientific name. A group of plants or animals that may reproduce together and have similar characteristics is referred to as a species.A collection of people with similar traits who can interbreed to create fruitful offspring is how species are frequently defined. Alpaca - Vicugna pacos are two examples. A group of creatures that can naturally reproduce with one another and generate viable progeny is sometimes referred to as a species. However, classifying a species can be challenging and even contentious. The billions of people on the planet now are all members of the same species, Homo sapiens. Human beings differ among themselves, just like other species do, in terms of everything from size and shape to skin tone and eye color. The two-part name that Linnaeus invented is still used today and is currently presented in either Latin or Greek. It was originally used for plants and then later for animals.

why is it imprtant to understand that racial categories are based upon perceptions of phentotypic features and not of genotypes
Is it crucial to recognize that racial classifications are based on perceptions of phenotypic characteristics rather than genetics due to the fact that race is socially rather than biologically generated.
What is meant by phentotypic?In genetics, an organism's phenotype is the collection of attributes or traits that can be seen in it. The expression alludes to an organism's morphology, and physical form and structure, including to its biochemical and physiological traits, behavior, and the results of that behavior. An observable characteristic is simply referred to as a "phenotype." Pheno, which has the same root as the term "phenomenon," simply means "observe." It can therefore refer to everything from a common attribute, like height and hair color, to the existence or absence of the a disease. This is also an observable type of the an organism. A clinical manifestation of the a person with a particular genotype; the observable characteristics of an individual which are the outcome of gene expression.
What are phenotypes examples and how you determine it?Examples of phenotypes in humans include height, blood type, eye color, freckles, & hair color. Phenotypes also include characteristics other than those of the physical body. A phenotype can also be a behavior.
We examine the alleles of a parent organisms and predict the frequency at which those genes would be expressed by the offspring in order to determine a phenotypic ratio. Almost all of the time, we were aware of the alleles' expression and appearance.

The process of glycolysis is the breakdown of fatty acids molecule in the body.
Glucose is metabolized to pyruvate by glycolysis in the cytoplasm, and pyruvate is fully oxidized to ATP by the TCA cycle and oxidative phosphorylation in mitochondria. Upon feeding, fatty acids are synthesized by de novo lipogenesis using products of glycolysis.
Glycolysis is the process by which glucose is broken down for energy. Produces his two molecules of pyruvate, ATP, NADH, and water. This process takes place in the cell's cytoplasm and does not require oxygen. Found in both aerobes and anaerobes.
This is the first step in cellular respiration. In glycolysis, sugar molecules are broken down to release the energy needed for cell metabolism. It is found in the cytoplasm of cells.

The correct option is B : Maintaining a constant supply and concentration of ATP. As we just saw, for cells to create and sustain the biological order that keeps them alive, they need a steady flow of energy.
Food molecules' chemical bonds, which act as the fuel for cells, are the source of this energy.

Messenger rna carries information from the dna to cellular components called , which play a key role in the synthesis of polypeptides.
The "machines" that propel protein synthesis are called ribosomes, which receive the protein blueprint from a cell's DNA via messenger RNA (mRNA).
What part in the synthesis does messenger RNA play?Messenger RNA provides the ribosome with the instructions needed to produce proteins. Amino acids are what proteins are made of. Transfer RNA is a different type of RNA that carries each amino acid in a protein to the ribosome.
What is the procedure by which a specific polypeptide is produced on a ribosome using an mRNA molecule?During translation, ribosomal subunits create a sandwich-like structure on the strand of mRNA. From there, they are drawn to the amino acids connecting tRNA molecules (circles). A long chain of amino acids is created as the ribosome transforms the mRNA sequence into a polypeptide, or new protein.
