As evidenced in the graph, the national average CO concentrations have decreased substantially over the years. All BUT ONE tactic
listed below has been utilized to reduce carbon monoxide emissions. That is:
Answer:
Explanation:
Carbon monoxide (CO) is a colourless, non-irritant, odourless and tasteless toxic gas. It is produced by the incomplete combustion of carbonaceous fuels such as wood, petrol, coal, natural gas and kerosene. Its molecular weight is 28.01 g/mol, melting point −205.1 °C, boiling point (at 760 mmHg) −191.5 °C (−312.7 °F), density 1.250 kg/m3 at 0 °C and 1 atm and 1.145 kg/m3 at 25 °C and 1 atm, and relative density (air = 1) 0.967 (1,2). Its solubility in water at 1 atm is 3.54 ml/100 ml at 0 °C, 2.14 ml/100 ml at 25 °C and 1.83 ml/100 ml at 37 °C.
The molecular weight of carbon monoxide is similar to that of air (28.01 vs approximately 29). It mixes freely with air in any proportion and moves with air via bulk transport. It is combustible, may serve as a fuel source and can form explosive mixtures with air. It reacts vigorously with oxygen, acetylene, chlorine, fluorine and nitrous oxide. Carbon monoxide is not detectable by humans either by sight, taste or smell. It is only slightly soluble in water, blood serum and plasma; in the human body, it reacts with haemoglobin to form carboxyhemoglobin (COHb).
The relationship of carbon monoxide exposure and the COHb concentration in blood can be modelled using the differential Coburn-Forster-Kane equation (3), which provides a good approximation to the COHb level at a steady level of inhaled exogenous carbon monoxide.
Conversion factors
At 760 mmHg and 20 °C, 1ppm = 1.165 mg/m3 and 1 mg/m3 = 0.858 ppm; at 25 °C, 1 ppm = 1.145 mg/m3 and 1 mg/m3 = 0.873 ppm.

Question
1. What happens to the host cell in the
lysogenic cycle?
Answer:
In a lysogenic cycle, the phage genome also enters the cell through attachment and penetration. ... During the lysogenic cycle, instead of killing the host, the phage genome integrates into the bacterial chromosome and becomes part of the host. The integrated phage genome is called a prophage.
Explanation:
Answer:
During the lysogenic cycle, the bacteria will enter the prophage and use its chromosomes to reproduce. This will continue until it eventually becomes the lytic cycle.

Cellular Respiration+ fermentation
Explanation:
Fermentation is another anaerobic (non-oxygen-requiring) pathway for breaking down glucose, one that's performed by many types of organisms and cells. In fermentation, the only energy extraction pathway is glycolysis, with one or two extra reactions tacked on at the end.
ANSWER FAST‼️‼️‼️Based on the information in the stimulus and Map 1, which
statements best explain why opal is found in places such
as Australia? Choose the two correct answers.
Answer:
Australia has large amounts of sandstone and silica.
and
Opal can only be formed where an ocean comes in contact with land.
Explanation:
because it needs standstone and a ocean to be able to create opal
Opal can only be formed where an ocean comes in contact with land. So, the correct option is (B).
What is an Opal?Opal is defined as a hydrated amorphous form of silica where the water content can range from 3 to 21% by weight, but is usually between 6 and 10%. Because of its amorphous property, opal is classified as a mineral, in contrast to the crystalline forms of silica, which are considered minerals.
Opal is arguably the most unique, diverse and beautiful, it does not have a defined crystalline structure which takes on many shapes and colors and thus is very unpredictable.
It can be formed where the sea is in contact with the sand, as in places such as those in Australia.
Thus, Opal can only be formed where an ocean comes in contact with land. So, the correct option is (B).

Genetic recombination occurs in many organisms. Which statement explains genetic recombination?
Answer:
D
Explanation:
Genetic recombination can be due to crossing over (which only occurs during meiosis). Genetic recombination is basically combinations of alleles that the parents don't have and because they are different from the parents, it leads to increased genetic variation.

How does using a microscope allow you to see what’s biotic or abiotic?
(how to know if a cell is abiotic or biotic)
Answer:
Abiotic factors refer to non-living physical and chemical elements in the ecosystem. Abiotic resources are usually obtained from the lithosphere, atmosphere, and hydrosphere. Examples of abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem.

Answer:
A and B: Presence of sugar
B, C, and D: Water temperature
B and E: type of respiration
Explanation:
consist of either one or two long chains of repeating units called nucleotides. DNA and RNA are the two main types.
Answer:
In case of both DNA and RNA, in general it is the nucleotides.
Nucleotides basically consists of three parts. The sugar(deoxyribose in DNA and ribose in RNA, both of which are pentose sugars), nitrogenous base and a phosphoric acid group.
The only component that varies in the nitrogenous base. There are five different types.
1.Adenine(A)
2.Guanine(G)
3.Cytosine(C)
4.Thymine(T)
5.Uracil(U)
1 and 2 are known as purines.
3, 4 and 5 are known as pyrimidines.
In DNA, A base pairs with T by means of a double hydrogen bond and G pairs with C by means of a triple hydrogen bond.
In RNA, A base pairs with U by means of a double hydrogen bond and G pairs with C by means of a triple hydrogen bond.
1) Two tubes are inoculated from the same tube containing a bacterial culture. The cultures are then transferred every day for two months. All of the media and growth conditions are the same in every tube. After two months of cultivation, the fitness and genotype frequencies of the populations in the two tubes are compared. The fitness of the two cultures is the same, but the genotype frequencies are very different in the two cultures. How is this possible
Answer:
The correct answer would be - Genetic drift within the small populations in the test tubes resulted in different genotype frequencies
Explanation:
Genetic drift is not like natural selection or adaptive radiation as it is a phenomenon that is random and does not takes place on the basis of genes being beneficial or harmful for survival. Genetic drift depends on any kind of error when the shift occurs in successive generations. Genetic drift also altered the allele frequency of a particular characteristic in future generations.
In this experiment, the sample cultures are transfer from one test tube to another on daily basis for a time period of two months There must be some sampling error that occured and caused the change in allelic frequency as natural selection cannot undergo under such a small population or within such short life span or time period only genetic drift can cause it.
