Answer:
c. A scientist discovers a new living organism that has no cells.
Explanation:
The cell theory is a widely accepted and globally recognized theory of living things. It was proposed in the 1830's by the collective effort of three scientists namely: Mathias Schleiden, Theodor Schwann and Rudolph Virchow. The cell theory is made up of three components as follows:
- All living things are made up of one or more cells.
- The cell is the basic and fundamental unit of life.
- All living cells comes from pre-existing cells.
According to this question, a new evidence that can possibly create a change in the cell theory is if a SCIENTIST DISCOVERS A NEW LIVING ORGANISM THAT HAS NO CELLS because all living organisms have been said to be made up of cells in the cell theory.
30 g of ammonia nitrate and nitrite are added to a soil sample. Predict whether these concentrations would increase decrease or stay the same if ammonia nitrifying bacteria were added to the sample 30 g of ammonia nitrate and nitrite are added to a soil sample. Predict whether these concentrations would increase decrease or stay the same if ammonia nitrifying bacteria were added to the sample
Answer:
See explanation
Explanation:
Nitrifying bacteria convert the most reduced form of soil nitrogen, ammonia, into its most oxidized form, nitrate(Science direct).
Nitrifying bacteria converts ammonia to nitites and finally to nitrates in the soil.
Hence, when 30 g of ammonia, nitrate and nitrite are added to a soil sample in the presence of nitrifying bacteria; the concentration of ammonia decreases over time while the concentration of nitrite and nitrate increases over time.
ammonia stays the same
nitrates decrease
nitrates increase

Which of the following are techniques besides molecular clocks used by scientist to calculate the rate at which a stretch of DNA changes? (Choose all that apply)
•comparison of human behaviors
•carbon dating of fossils
•comparison of blood proteins
•comparison of homologous structures
Answer:
B and D
Explanation:
Human behaviors do not affect the entire evolution of every lifeform that has existed, therefore, A is FALSE
Carbon dating is commonplace in figuring out how old a lifeform could be, therefore, B is CORRECT
Blood proteins are commonly known to not last long and decompose fast, so fossilization of blood tends to not happen, plus it's next to impossible to tell what species had that genetic data, therefore, C is FALSE
For D, I kinda forgot most of my explanation, but I remember that it's correct, as I got the question correct on the assignment.
The carbon dating of fossils and comparison of homologous structures are techniques besides molecular clocks used by scientist to calculate the rate at which a stretch of DNA changes.
So, option B and D are correct one.
Human behaviors do not affect the entire evolution of life of organism that has existed, therefore, A is FALSE
Carbon dating is commonplace in figuring out how old a life of any organism, therefore, B is CORRECT
Blood proteins are commonly known to not last long and decompose faster, so fossilization of blood tends to not happen, plus it's next to impossible to tell what species had that genetic data, therefore, C is FALSE
By comparing of homologous structures we determine nucleotide sequence exchanged between two similar or identical molecule of DNA. So, option D is correct
What is Carbon dating?It is also referred as radiocarbon dating.It is the method used to determine the age of the living organism containing organic( carbon ) based material by using isotopes of carbon which is radioactive.Learn about carbon dating

Explanation:
In what respect is a mycelium and a fruiting body similar?
Both are made of hyphae.
Both are found above the ground.
Both produce reproductive spores.
Both absorb nutrients underground.
Both produce reproductive spores. Therefore, option (C) is correct.
What are reproductive spores?Reproductive spores are specialized structures produced by certain organisms for the purpose of reproduction. Spores are single cells or groups of cells that are capable of developing into new individuals under suitable conditions. They are typically small, lightweight, and highly resistant to environmental conditions, allowing them to disperse over long distances.
Various organisms produce reproductive spores, including fungi, algae, plants (such as mosses and ferns), and some bacteria. These spores serve as a means of reproduction and dispersal, enabling these organisms to colonize new habitats and propagate their species.
Reproductive spores can be produced through different mechanisms, such as asexual or sexual reproduction. In some cases, spores are released into the surrounding environment and can be carried by wind, water, or other organisms, allowing for widespread distribution and colonization.

Which part of the nucleotide codes for out traits?
The nitrogenous bases which are the part of nucleotide codes for out traits. Nitrogenous bases are of two types: Purines and Pyrimidines.
What are Nitrogenous bases?Nucleobases are also known as nitrogenous bases. These are the nitrogen-containing biological compounds which form nucleoside units, which, in turn, are components of the nucleotides, with all of these monomeric units that are constituting of the basic building blocks of nucleic acids.
The ability of the nitrogenous bases to form base pairs and to stack one above the another leads directly to a long-chain helical structure such as ribonucleic acid (RNA) and deoxyribonucleic acid (DNA) molecules. Five nitrogenous bases include adenine (A), cytosine (C), guanine (G), thymine (T), and uracil (U). They function as the fundamental units of the genetic code in living organisms, with the bases A, G, C, and T being found in the DNA molecule while A, G, C, and U are found in the RNA molecule.

Choking on food is most likely caused by an interference with the proper functioning of the oesophagus.
What is oesophagus?
The digestive system, sometimes known as the gastro-intestinal tract, includes the oesophagus (gullet) (GI tract). An oesophageal tube is made of muscles. It joins the mouth with the stomach.
The oesophageal walls contract together as you swallow food (contract). This causes the food to travel from the mouth to the stomach.
The diaphragm is a layer of muscle located below your lungs. It facilitates breathing. The majority of your oesophagus is located in your chest above the diaphragm.
Therefore, Choking on food is most likely caused by an interference with the proper functioning of the oesophagus.

When oxygen is released as a result of photosynthesis, it is a direct by-product of splitting water molecules.
PHOTOSYNTHESIS:
Photosynthesis is the process whereby green plants obtain their food (glucose) using energy from sunlight. Photosynthesis occurs in two stages namely: light dependent reaction and light independent reaction. In the light dependent reaction, chlorophyll molecules absorb light and the released electron is used to split water molecules into hydrogen and oxygen gas. Therefore, the release of oxygen gas is a direct byproduct of the splitting of water molecules called photolysis.Learn more at: https://brainly.com/question/25027435?referrer=searchResults
