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

Answer:
C. P -› F1 -› F2
Explanation:
In genetics and breeding, the following symbols represents the following:
P => parental
F1 => First filial generation
F2 => Second Filial generation
The crossing of two parent plants (P) produces offspring that is tagged the first filial generation (F1). The next cross involving the F1 offspring produced second filial generation (F2).
Therefore, the correct sequence is:
P -› F1 -› F2

Answer:
1) Gravitational force is an attraction between masses. The greater the size of the masses, the greater the size of the gravitational force.
2) The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it.
3) There are the two components of the projectile's motion - horizontal and vertical motion.
4) The sun's gravity pulls the planet toward the sun, which changes the straight line of direction into a curve. This keeps the planet moving in an orbit around the sun. Because of the sun's gravitational pull, all the planets in our solar system orbit around it.

Choking on food is most likely caused by an interference with the proper functioning of the...
Answer:
esophagus
Explanation:
the esophagus is the pipe/muscle that leads to your stomach
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.

Which of these statements accurately describes the energy conversion that occurs in cellular respiration?
A) ATP is converted into thermal energy.
B) Chemical energy is converted into ATP.
C) Heat energy is converted into chemical energy.
D) Light energy is converted into kinetic energy into the products.
Chemical energy is converted into ATP in cellular respiration. Therefore, option B is correct.
What is cellular respiration?The process of cellular respiration involves the oxidation of biological fuels in the presence of an inorganic electron acceptor, like oxygen, to generate significant amounts of energy that are used to power the major creation of ATP.
Both the cytosol and mitochondria of cells participate in cellular respiration. While pyruvate oxidation, the Krebs cycle, and oxidative phosphorylation take place in the mitochondrion, glycolysis happens in the cytosol.
The primary goal of cellular respiration is the production of energy, even though it can also result in the production of other substances like lactic acid or carbon dioxide. Every biological process requires energy. Therefore, option B is correct.
