Deadly gas. Carbon monoxide is a colorless, odorless gas that binds to hemoglobin at an oxygen-binding site. Indeed, it binds 200 times as tightly as oxygen, accounting for its toxic nature. Even if only one of the four oxygen-binding sites on hemoglobin is occupied by carbon monoxide and the remaining three are bound to oxygen, oxygen is not released. Explain.

Answers

Answer 1

Answer:

The binding of carbon monoxide (CO) with hemoglobin leads to an R state even in conditions that should produce the release of oxygen. In consequence, CO-hemoglobin binding shifts the oxygen dissociation curve to the left.

Explanation:

Hemoglobin is a globular protein containing four heme groups that can bind to one oxygen each. This protein (hemoglobin) has two conformational states: the T-state, also known as deoxyhemoglobin (a tense state, where lacks O species), and the R-state, also known as oxyhemoglobin (a relaxed, fully oxygenated state). When carbon monoxide binds to hemoglobin, the protein can not release oxygen, shifting the oxygen dissociation curve -which expresses the percentage of oxygen saturation against the partial pressure of oxygen- to the left. Therefore, under CO-hemoglobin binding, the oxygen level in the tissues is reduced.

As per the weather map of north America the regions of high and low pressure are given along with the cloudiness and range of temperatures

The warm and fold fonts are affected by the cloud covers and hence affect the temperature of the region. The cold front will be along the borer of 40 and 50°. The northeastern region shows maximum cloud cover and a low pressure. As compared to the western and southern region have have high temperatures and experienced high pressure. The winds will below from the high pressure to low pressure and hence create instability cover the north eastern parts.

Hence the fronts are located north east and central zone.

What if cellular respiration did not occur

Answers

Answer:

cellular respiration is a process that needs oxygen, so when oxygen is not present, they do not happen, but there is glycolysis, which doesn't need oxygen. the process of glycolysis produces 2 ATP and that is what is needed, so to continue glycolysis, the cells go through fermentation.  

Explanation:

THE ANSWER IS FERMENTATION!!!!

Answer:

If cellular respiration does not occur, then the level of oxygen present in the cell will get decreased as a result cell can die due to lack of oxygen. This is because cellular respiration provides the energy necessary for cellular activities.

Why is diffusion such an efficient process
for all cells?
A. It does not require energy.
B. It occurs so quickly.
C. The high amount of energy used during diffusion is offset by
the amount it creates.

Answers

Answer:

A.

Explanation:

Diffusion does not require energy. It's depends on the concentration gradient of the two molecules.

Diffusion is such an efficient process for all cells because it does not require energy. Thus, the correct option is A.

What is Diffusion?

Diffusion may be defined as the migration of substances from a region of higher concentration to a region of lower concentration through a semi-permeable membrane.

Diffusion does not require any type of energy for the movement of ions, molecules, or substances. It is a very feasible form of migration of substances.

Diffusion is a type of passive transport and hence takes place in a dropping manner without any expenditure of energy.

Therefore, Diffusion is such an efficient process for all cells because it does not require energy. Thus, the correct option is A.

The order of the genes on a plant chromosome is A, B, C, where A and B are located 10 cM apart and B and C are located 3 cM apart. What is the probability that the trihybrid ABC/abc will produce any kind of recombinant gamete

Answers

Answer:

Double Crossing-over prob = 0.3% Simple Crossing-Over prob A-B = 9.7%Simple Crossing-Over prob B-C = 2.7%Total Crossing-Over prob = 12.7%

Explanation:

Available data:  

order of the genes on a plant chromosome is A, B, CA and B are located 10 cM apartB and C are located 3 cM apart

The genetic distance = recombination frequency x 100 expressed in map units (MU). One centiMorgan (cM) equals one map unit (MU).

We can use the provided map with the distances between genes to predict the occurrence of any kind of recombinant gamete.  

We know that there is a probability of a simple crossing over to occur between genes A and B, or between genes B and C. And we also know that there is a probability of double crossing-over occurrence.

We can get the probability of the double-crossing over by multiplying the recombination frequencies between A-B and B-C. So,

DCO prob = recombination frequency A-B x recombination frequency B-C

                 = 0.1  x  0.03 = 0.003 = 0.3%

DCO prob = 0.3%

According to this, we would expect to find

0.15% AbC0.15% aBc

Now we need to know what are the probabilities of getting a simple crossing-over, SCO. We already have the genetic distances between genes. 10 cM equals 0.1 of recombination frequency, and 3cM equals 0.03 of recombination frequency. However, we can not estimate the probabilities of simple crossing over using only this information, because this data is including the probabilities of the double crossing-over occurrence. So we need to substrate this percentage.    

SCO prob A-B = 0.1 - 0.003 = 0.097 = 9.7%

SCO prob A-B = 9.7%

we would expect to find

4.85% Abc4.85% aBC

SCO prob B-C = 0.03 - 0.003 = 0.027 = 2.7%

SCO prob B-C = 2.7%

we would expect to find

1.35% ABc1.35% abC

The total Crossing-over probability, TCO, is then the sum of all the crossing over probabilities,

TCO= SCO A-B + SCO B-C + DCO

TCO prob = 9.7% + 2.7% + 0.3%

TCO = 12.7%

Hydrogen bonding is primarily responsible for the high ______ of water.
a. freezing point
b. boiling point
c. conductivity
d. polarity

Answers

The hydrogen bond is responsible for many of the anomalous physical and chemical properties of compounds of N, O, and F. In particular, intermolecular hydrogen bonding is responsible for the high boiling point of water (100 °C) compared to the other group 16 hydrides that have much weakerhydrogen bonds

Explanation:

Therefore, option b is correct.

Hydrogen bonding is primarily responsible for the high boiling point of the water. Thus, the correct option is B.

What is Hydrogen bonding?

Hydrogen bonding is an interaction which involves a hydrogen atom that is located between a pair of other atoms such as nitrogen, oxygen, and fluorine which have a high affinity for electrons, and such a bond is weaker than an ionic bond or a covalent bond but are stronger than van der Waals forces and dispersion forces.

Hydrogen bonding is primarily responsible for the high boiling point of water solvent. Hydrogen bonding is a strong affinity. Hydrogen bonding is created when a hydrogen atom is bonded to an electronegative atom by approaching a nearby electronegative atom.

Therefore, the correct option is B.
