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 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.

•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

D) chemiosmosis.
E) reducing NADP-.
Answer:
A) splitting water molecules I believe
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
Suppose you are a planner who is working for the German government. You & other planners must decide how to use tax money to develop renewable energy resources.
Would you spend tax money on developing sources of geothermal energy? Why or Why not?
Answer:
Yes
Explanation:
Geothermal is renewable energy generated from the Earth's heat. If anything, the Earth will continue to release heat until the sun blows up in a billion years (unless something is wrong with the Earth lol)
As a planner for the German government, I would absolutely think about investing tax dollars in the creation of geothermal energy sources. Geothermal energy is a renewable and sustainable energy source that may be utilised to produce power, heat and cool spaces, among other things.
How Geothermal energy's is dependability ?Geothermal energy's dependability and predictability are two of its key benefits. Geothermal energy has the potential to offer a consistent and reliable source of heat and electricity, unlike wind and solar energy, which are reliant on the weather.
Additionally, geothermal energy is an environmentally responsible choice because it is a clean form of energy that emits no greenhouse gases or air pollution.
Germany has a long history of using geothermal energy for heating, and it has the potential to increase that use to include geothermal energy generation for electricity.
The price of geothermal energy has been falling as a result of the development of new technologies, making it more inexpensive and competitive with other energy sources.

A. Mutations creating new alleles occur more frequently in this species of bacteria than in other species.
B. Crossing over during meiosis increased genetic variability in the bacteria.
C. The bacteria have high genetic variability and high reproductive rates.
D. The bacteria are able to recognize and destroy the antibiotics by breaking them down extracellularly
Answer:
C. The bacteria have high genetic variability and high reproductive rates.
A current challenge for doctors involves the bacterial strain Clostridioides difficile, which does not respond to traditional antibiotics because bacteria have high genetic variability and high reproductive rates, which are present in Option C.
What causes such rapid antibiotic resistance?Antibiotic resistance occurs when bacteria develop the ability to survive against the antibiotics, and this can happen for several reasons, including overuse and improper use of antibiotics as well as the natural ability of bacteria to adapt and evolve because they can reproduce rapidly and generate many offspring in a short period of time that can possess the gene that destroys the antibacterial drugs.
As a result, a current challenge for doctors involves the bacterial strain Clostridioides difficile, which does not respond to traditional antibiotics because bacteria have high genetic variability and high reproductive rates, which are present in Option C.

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.
