The statement " Four factors which need to be balanced properly for a cell in order to be healthy are temperature, chemical content, volume as well as pressure" is 'True'.
The given statement is 'True' as a healthy cell functions best at normal physiological temperature which comes out to be 98.6 Fahrenheit in warm-blooded animals including human beings. Increased temperatures can increase the fluidity of cell membranes which can alter the permeability of the cell. Due to this some harmful substances can enter the cell.
The chemical contents of the cell comprises of four basic organic constituents, i.e. protein, lipid, nucleic acid and carbohydrate. These biomolecules play a crucial role in carrying out various cellular functions. Volume and pressure also need to be balanced properly in a cell to be healthy.

Over the years, scientists have developed several systems for the classification of organisms. From the late 1960s, organisms had been classified
according to a five-kingdom system. This classification system model was based on principles developed by Swedish scientist Carolus Linnaeus, whose
hierarchical system groups organisms based on common physical characteristics. This system recognized five kingdoms: Monera (bacteria), Protista,
Fungi, Plantae, and Animalia. The scheme divided life into two main divisions based on cell structure: the Prokaryotae (bacteria) and the Eukaryota
(animals, plants, fungi, and protists). As scientists learned more about organisms, classification systems changed. Genetic sequencing has given
researchers a new way of analyzing relationships between organisms. The current system, the three-domain system, classifies organisms primarily
based on differences in ribosomal RNA (rRNA) structure. Under this system, organisms are classified into three domains and six kingdoms. The domains
are Archaea, Bacteria, and Eukarya: two prokaryotic domains and one eukaryotic. Recent work in the classification of life has shown that what was once
called prokaryotes are much more diverse than previously suspected. The prokaryotic domains also represent two distinct kingdoms, the Eubacteria,
and the Archaebacteria, and are as different from each other as either is from the Eukaryota. The kingdoms are Archaebacteria (ancient bacteria),
Eubacteria (true bacteria), Fungi, Plantae, Protista, and Animalia. The Eukarya domain includes eukaryotes or organisms that have a membrane-bound
nucleus. Eukaryotes have rRNA that is distinct from bacteria and archaeans.
Can you distinguish life in the thee domains and kingdoms?
The single feature that separates the domains in the cladogram is cell structure.
Based on this classification system, we can say that plants and animals are more alike than plants and
bacteria.
The domains Archaea and Bacteria differ from each other biochemically.
The domains Archaea and Bacteria both have organisms composed of prokaryotic cells.
The Archea are more closely related to the Eukarya than they are to the Bacteria.
According to this cladogram, scientists believe that all kingdoms evolved from a common ancestor HELP!!!!!

Why are Hydrogen bonds similar to ionic bonds?
Answer:
Hydrogen bonds are similar to ionic bonds because they both involve the attraction between opposite charges. During an ionic bond one atom donates electrons to another atom. This creates one atom with a negative charge, called an anion, and one atom with a positive charge, called a cation.

Pick an organism and tell me, in great detail, how that organism maintains homeostasis.
In order to maintain homeostasis, the desert rat:
lives in burrows built in the desertmaintains a nocturnal lifestyle has little fur What is homeostasis?Homeostasis is the process by which a living organism maintains a fairly constant internal environment.
Homeostasis refers to the mechanisms by which a organism responds to internal as well as external environmental changes.
All living organisms possess a mechanism for maintaining homeostasis.
A typical organism that maintains homeostasis is the desert rat.
The desert rat lives in the very harsh environment of the desert where there is extreme heat.
In order to maintain a fairly constant internal environment, the desert rat lives in burrows built in the desert. Also, the desert rat maintains a nocturnal lifestyle coming out in the dark when the temperatures have reasonably cooled.
Also, the desert has little fur so that the body can easily lose heat.

What is an enzyme substrate?
A molecule with which an enzyme interacts is known as a substrate. A substrate is put into the active site of the enzyme, which is where weak bonds between two molecules might form. The substrate reacts under the pressure of the enzyme, forming an enzyme-substrate complex that is the product of the intended reaction.
The bonds that form between the substrate and the enzyme are what induce the conformational shift, or shape change, in the enzyme. The resulting shapeshift, which either pulls molecules together or splits them apart, is what exerts pressure on the substrate.
A substrate is a material that an enzyme uses in an enzymatic process. By reducing the activation energy required for the process, enzymes operate as biological catalysts to speed up chemical reactions.
In a chemical reaction, an enzyme is a protein that catalyzes the transformation of a substrate reactant into a product. In general, individual enzymes have a variety of substrates and may be tailored to a variety of reaction intermediates that are a part of a larger process.
Therefore the correct option is A.

A basic amino group (NH2), an acidic carboxyl group (COOH), and a specific organic R group (or side chain) are the three organic molecules that make up an amino acid. Alpha-amino [alpha-amino] carboxylic acid is referred to as an amino acid informally. An amino and a carboxyl group are both joined to the core carbon (C) atom, known as the -carbon, in every molecule. A hydrogen (H) atom and the R group typically fulfill the remaining two bonds of the -carbon atom. The building components of proteins are amino acids.

Explanation:
how does the cycle of matter and energy flow through ecosystems relate to interactions occurring in the ecosystem?
Decomposers receive matter and energy from dead producers, consumers, and the waste they make. The matter is converted back into inorganic forms by decomposers so that it can be recycled into the ecosystem.
So, the energy that comes from sunlight entering an ecosystem eventually leaves the ecosystem as heat.
Energy and materials are transformed from one form to another in ecosystems.All of the objects in that environment, both living and nonliving, are referred to as matter. Decomposers then break down the nutrients and living matter that have been passed from producers to consumers. Energy is transported between organisms in food webs from producers to consumers as decomposers break down dead plant and animal debris. Organisms utilise the energy to accomplish challenging activities.Learn more about ecosystem here:

An extensive research has been done to understand the role of environmental factors in the process of unregulated cell division. Four scientists including Higginso, Muir, Doll and Peto in 1977 tried to explain that 80 percent of all types of cancer were caused due to environmental factors.
However, modern studies suggest that unregulated cell division results from both, environmental factors as well as genetics. Radiation, toxins and certain chemicals or drugs can lead to the development of cancer following unregulated cell division.
