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.

What is evolution? How can evolution be scientific when no one was there to see it happen?
Answer:
Evolution is looking back and using scientific inference to make a timeline on adaptation of a species over time.
Explanation:
Looking at skulls, skeletal remains and carbon footprints left behind, we can compare and date remains of early humans and other species from years ago and compare them to late and modern remains. Thus making a timeline and showing the slow evolution of our adapting species.
Which of these describe(s) variation within a species or population?
(A population is defined as members of the same species living together in the same area and who are likely to breed with each other.)

A human body cell has 46 chromosomes. How many chromosomes does a human egg or sperm cell have?
Answer:
IT HAS 35 sperm cells
Explanation:
Answer:
23 chromosomes
Human somatic cells have 46 chromosomes consisting of two sets of 22 homologous chromosomes and a pair of nonhomologous sex chromosomes. This is the 2n, or diploid, state. Human gametes have 23 chromosomes or one complete set of chromosomes.

During which phase of the cell cycle will organelles and proteins be made
to prepare for cell division?
Answer:
S phase: synthesis phase; the cell synthesizes a complete copy of the DNA in its nucleus. G 2start subscript, 2, end subscript phase: second gap phase; the cell grows more, makes proteins and organelles, and begins to reorganize its contents in preparation for mitosis.

5. Which process usually results in offspring that exhibit new genetic
variations?
Answer:
It's the first choice that is fertilization
The process that usually results in offspring that exhibit new genetic variations is known as fertilization. Thus, the correct option is 1.
What is Genetic variation?Genetic variation may be defined as the occurrence of differences in sequences of genes between individual organisms of a species. The most prominent causes of genetic variation are mutations, sexual reproduction, gene flow, genetic drift, etc.
The first option describes the process of successful fertilization between male and female gametes. Thus, this sexual reproduction is the most characteristic process of inducing genetic variations among individuals of the same species.
The option third illustrates the process of budding in hydra, and the option reveals the process of binary fission in amoeba. Both are types of asexual reproduction in which the offspring is produced by a single parent only. And hence, they produce identical types of offspring without much genetic variations.
Therefore, the process that usually results in offspring that exhibit new genetic variations is known as fertilization. Thus, the correct option is 1.

What would happen to the nitrogen cycle if bacteria was no longer present
Answer: Without bacteria around to break down biological waste, it would build up. And dead organisms wouldn't return their nutrients back to the system.
Explanation:
The simplest way to explain it is:
Without bacteria, the nitrogen cycle would stop.
Bacteria is responsible for converting ammonia into nitrogen in soil. The nitrogen feeds plants which all go hand-in-hand with all of the Earth's cycles.

Is nitrogen gas useless to animals?
Answer:
Animal cells can only use nitrogen when it's combined with other elements.
Explanation:
Brainliest?
Answer:
It isn't useless to land animals.
Explanation:
The air we breathe is actually only 21% oxygen. The rest of that 78% is nitrogen gas. So land animals that breathe need nitrogen gas to live.
Sulfur dioxide is considered a serious air pollutant. SO2 emissions that lead to high concentrations of SO2 in the air generally also
lead to the formation of other sulfur oxides (SOx). SO, can react with other compounds in the atmosphere to form small particles, and
these particles contribute to particulate matter (PM) pollution. Small particles may penetrate deeply into the lungs and in sufficient
quantity can contribute to health problems. Which of these is NOT a source of SO2 pollution?
A)
manufacture of cement
B)
extracting metal from ore
burning fossil fuels by power plants

trains, ships and heavy equipment that burn high sulfur content fuel
