Which is a leading theory for the formation of fossil fuels?

Biology
1 answer:
Mumz [18]2 years ago
5 0

Answer:

The most generally accepted explanation for fossil fuel production is that, over time, fossil fuel was formed from declining organic matter. Organisms died and were buried in the earth millions of years ago. The carbonaceous substances within the humans, subjected to the high temperature and pressure below the earth's surface, were converted into types of fossil fuel such as coal and oil.

The bulk of carbon dioxide is carried chemically combined with the amino acids of hemoglobin as carbaminohemoglobin in the RBCs.
e-lub [12.9K]

Answer: True

Explanation:Carbon dioxide is transported is transfer in 3 basic ways to human cells.

About 20 % of C0 2 is transported as Carbaminohemoglobin to reach the lungs carbon dioxide binds directly to the amino acid moieties on the globin portions of the haemoglobin to form carbaminohemoglobin. This is a reversible reaction as shown below.

                                        CO2 + Hb ↔ HbCO2.

The reversible binding of C02 to the haemoglobin is due to the   the partial pressure of carbondioxde. In  the  lungs the partial pressure of C02 is low. Therefore C02 is unbounded from the HB and leaves in the lungs, thus the blood   leaving the lungs for the body tissues has low partial pressure C02. Compare to the blood in the tissues with high partial pressure of C02 from metabolic activities of cellular respiration. The C02 therefore diffuses from the tissues to bind with HB to form Carbaminoheamologbin.

In addition C02 is transported by other means.

1. As bicarbonate 70% of the Co2 in the blood is transported and  bicarbonate buffer.

              CO2 + H2O CA ↔ H2CO3↔H+ + HCO3

2, As  soluble carbon dioxide which  dissolves directly  in to the blood stream; this is about 7-10%

You are operating a powerboat at night. Your red sidelight must be visible to boats approaching from which direction(s)?
Degger [83]
I believe the answer is head-on and port (left). The side lights are usually visible to vessels approaching from the front or the side. The red light usually indicates a vessel's port (left) side while the green light indicates a vessel's starboard (right) side. These lights ensure that there is safety at night as the vessels navigate.

Which of the following does NOT describe bacteria? They help break down dead organic material so it can be recycled into a usabl
vovangra [49]
I think the correct answer would be the third option. Organisms that help break down dead organic material so it can be recycled into a usable form for other organisms are called decomposers and this would include some of the bacteria. Also, there is a number of bacteria that are capable of breaking down some of the harmful products like in recent studies there are bacteria that could dechlorinate the toxic PCB substance. Some bacteria, as well, lives in the human intestines which aids in the breaking down of the food into useful molecules. The third option is partially true since there are some bacteria like the cyanobacteria which produces oxygen but it does not contribute largely to the oxygen present in the atmosphere.

Skin color in a certain species of fish is inherited by a single gene with four different alleles. How many different types of g
k0ka [10]

Answer:

4

Explanation:

According to Mendel's law of purity of gametes, each gamete contains single allele for a gene. The alleles of a gene segregate during gamete formation and each gamete has one allele for a gene irrespective of the total number of alleles for a gene.  

If the gene for skin color in a fish species has four alleles, an individuals fish would have only two alleles which in turn would segregate during gamete formation.

Since there are four different alleles of the gene (let's assume a,b,c, and d), total possible gametes produced by this organism will be = 4. A gamete can have one of the total 4 alleles making total 4 types of the gametes each with a or b or c or d allele.
