Answer 1
Answer:
Viruses: Found in extreme environments. Cannot survive outside of a host cell, can only be seen with an electron microscope
Fungi: Obtain nutrition from organic or inorganic sources or carry out photosynthesis. It is not usually associated with human diseases. Eukaryote: It can be unicellular or multicellular.
Bacteria: They have cell walls that contain peptidoglycan. Found in extreme environments (via spores)
Explanation:
In the part of the answer, the answer was given by grouping the different characteristics of the microorganisms, classifying them into three groups.
Viruses are considered microorganisms that need the replicative machine to reproduce their RNA or DNA, this is how it is doubted whether they are living organisms or not.
Fungi belong to a very broad group of subtypes, but they all refer to the fungi kingdom, they are in the form of spores in the soil or in the air, those fungi that are considered pathogens for humans, such as the generators of histoplasmosis, or blastomycosis. Most fungi are not pathogenic to our body, so some are edible, such as yeast.
On the other hand, and finally we have bacteria, which are a family that is classified into many groups according to their genus and species, their shape is what determines their nomenclature, such as those coconuts, which are grouped together in a of bunch of grapes and are called thus streptococcus in synonymous to this method of colonization and form. Many bacteria are typical of our commensal flora or microbiota, others are not, thus generating opportunistic infections or severe infections.

Enzymes are a type of protein that speed up chemical reactions.
All enzymes are examples of organic molecules known as proteins.
Proteins are large biomolecules composed of one or more chains of amino acids that perform a wide range of functions in living organisms. Proteins are essential structural and functional components of cells, tissues, and organs.
Enzymes are biological catalysts that are produced by living cells. They are typically composed of one or more proteins, which are long chains of amino acids that are folded into complex three-dimensional shapes. Enzymes play a critical role in many biological processes, including digestion, metabolism, and DNA replication. \They work by lowering the activation energy required for a given chemical reaction to occur, which allows the reaction to proceed more quickly and efficiently.
Therefore, enzymes are proteins, they are considered to be organic molecules.

Which of the following is NOT a part of cell theory a.All living things are made of one or more cells. b.All cells are Eukaryotic cells. c.Cells are the basic unit of life. d.Cells come from pre-existing cells.
Answers
Option b. "All cells are Eukaryotic cells" is not a part of cell theory.
Cell theory refers to the belief that all living things are made up of one or more cells that unite to form the whole body/structure/organism.
It is universally known that cells are the smallest unit of living things. Without them, there can be no structure or organism made or formed.Cell theory provides the basic description of the properties of cells.And this cell theory was developed by three major scientists- Matthias Schleiden, Theodor Schwann, and Rudolf Virchow.The trio believed that cells, being the alpha of human life, are an important element of living things.They then came upon three basic points that they term "cell theory", which states that all living things are made of one or more cells.They also stated that cells are the basic unit of life and that they come from pre-existing cells.And that cells can be either one of the two- Eukaryotic or Prokaryotic cells.The statement that all cells are Eukaryotic in nature is false because Eukaryotes are cells with a clearly defined nucleus.This means that larger organisms like animals, plants, and fungi are Eukaryotes whereas smaller ones like bacteria and Archaea do not have a membrane-bound nucleus, making them Prokaryotes.
While it is understood that cells are the basic unit for living beings, there are certain points that make them important. But one statement that is wrong about the cell theory is that all cells are Eukaryotic cells. Thus, option b is the correct answer.

Answers
Answer:
B.) The movement of metals in Earth's core and Earth's rotation
Explanation:
got a 100 on the Test
The two processes that are involved in the formation of Earth's magnetic field are the movement of metals in Earth's core and Earth's rotation. The correct option is B.
What is a magnetic field?
A magnetic field is a place near a magnet in which a physical field is created with the electric charge. The field applies a great force on the other objects which come into this physical field.
Earth's core is the center point of earth, which is in a molten state and contains a high amount of iron. The core of the earth maintains the revolving of the earth as it is attracted by a magnetic field.
Due to gravitational force, the earth rotates on its axis and around the sun. Earth takes around 24 hours to revolve on its axis and 365 days in revolving around the sun.
Thus, the correct option is B. the movement of metals in Earth's core and Earth's rotation.

Why is the fossil record biased
Answers
Answer:
We don't have every organism that existed identified in the fossil record.
Explanation:
The fossil record is biased because we don't have a complete record of every organism that lived on Earth. It also favors organisms that had structures capable of being preserved.
From Penn Foster
Due to the fact that many early forms of life had soft bodies, the fossil record has gaps, soft creature components do not make good fossils.
What is the fossil record?
This indicates that little is known about how these creatures appeared, any fossil remains that may have existed have likely been obliterated by geological processes.
One analysis of the fossil record, which revealed that a staggering 97% of palaeontological data originate from experts in high- and upper-middle-income nations, cautions that our knowledge of the history of life on Earth is biased towards the opinions of wealthier countries.
Therefore, due to geological, physical, chemical, and biological considerations, the fossil record is not only inaccurate, but it also has intrinsic biases.

what happens to the C6H12O6 when it is eaten by elk
Answers
Answer:
There are no options but the answer can be provided based on general understanding. The answer is:
It is used to synthesize energy (ATP)
Explanation:
C6H12O6 is the chemical formula for glucose molecule, which is a simple sugar or monosaccharide. It is the simplest unit of carbohydrate molecules. Glucose is a precursor of cellular energy i.e. ATP in living systems. When food is eaten by an organism such as elf, it gets broken down or digested to a simpler unit, which is usually glucose.
This glucose is then absorbed by the cells of the organism, where the stored energy in its bonds is converted to a usable energy by the cell, called Adenosine triphosphate (ATP) in a process called CELLULAR RESPIRATION. Hence, the C6H12O6 (glucose), when eaten by an organism such as an elk, is used as a source of energy to the cell.

What are two abiotic and two biotic conditions in a coral reef that provide the conditions necessary for it to have high biodiversity? How could a disturbance affect the biodiversity of the coral reef?
Answers
Answer:
The two abiotic conditions in the coral reef that contribute to the high biodiversity are:
TemperatureSunlight
Whilst the abiotic factors are
Plant and Bacteria
Explanation:
The coral reef which covers a space of 115,831 square miles (or 30 million hectares os space) is home to a rich diversity of aquatic life (plants and animals alike). Being the largest coral reef on earth a lot of attention is given to it to ensure that its health and functionality is preserved.
The above factors contribute immensely to the stability and operability of the great reef.
The coral reef abounds with many aquatic animals such as crabs, herbivorous fish, sea turtles, sea urchins etc Many of these feed off microscopic plants such as the phytoplankton (that is tiny plants) and microscopic animals referred to as zooplankton. The zooplankton in turn feed off microscopic plant, bacterioplankton and even other zooplankton.
It is easy to see that at the base of the food chain lies Phytoplankton and bacterioplankton. This group require sunlight to thrive.
The smaller herbivorous fish, crabs, sea turtles and urchins on the other hand, constitute food for larger animals such as sharks, Baracuda etc.
It is also important to note that these microscopic life (plant and animals) require a certain temperature to thrive. If the water body in these eco system were to exceed a certain temperature, it is highly doubtful that they would survive. The death the the plant and animal life at the base of the food chain will completely disrupt the entire biodiversity and may even lead to its extinction.
