Answer:
So where does the mass come from? The mass of a tree is primarily carbon. The carbon comes from carbon dioxide used during photosynthesis. During photosynthesis, plants convert the sun's energy into chemical energy which is captured within the bonds of carbon molecules built from atmospheric carbon dioxide and water.

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

Answer: Plasma membrane
Explanation:
According to endosymbiont theory most of the membrane bound cell organelles like nucleus, Golgi bodies, and endoplasmic reticulum are originated from plasma membrane in the deep folds. This theory also suggests that chloroplast and mitochondria are originated from the bacterial cells or primitive prokaryotic cells. These are the organelles chiefly present in the eukaryotic cells. This theory suggests that primitive earth was supported by the bacteria.

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.

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:

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.

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

Cross two pink snapdragons. What is the genotypic and phenotypic probability of such a cross?
Answer:
Genotypic probability = 1RR: 2Rr: 1rr
Phenotypic probability = 1Red: 2Pink: 1white
Explanation:
This question involves a single gene coding for skin color in snapdragon plants. The alleles are incompletely dominant over one another and hence, produce an intermediate pink phenotype.
According to this question, two pink/heterozygous snapdragons were crossed i.e. Rr × Rr. Each parent will have gametes R and r. Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
Genotypic probability = 1RR: 2Rr: 1rr
Phenotypic probability = 1Red: 2Pink: 1white
