What is the most important part in the respiratory system?
The lungs.
The lungs are paired, cone-shaped organs which take up most of the space in our chests, along with the heart. Their role is to take oxygen into the body, which we need for our cells to live and function properly, and to help us get rid of carbon dioxide, which is a waste product.
How is relative dating of fossils different from absolute dating?
Answer:
Absolute dating is the actual date of the rock and can also been known as radioactive dating. Relative dating is using the rock layers and fossil records to determine the age of the rock, and it is not the actual age of the rock. :)

When a filament of algae is illuminated with light that is passed through a prism, different segments of algae are exposed to different wavelengths of light. When aerobic bacteria are present, they congregate in highest concentrations in the areas illuminated by the red and blue light. These data suggest a relationship between which of the following variables?
a) Wavelength of light and rate of aerobic respiration
b) Wavelength of light and amt of heat released
c) Wavelength of light and the rate of photosynthesis
d) Carbon dioxide concentration and the rate of photosynthesis
Answer:
The correct answer is C) wavelength of light and rate of photosynthesis.
Explanation:
The given question is a famous experiment conducted by T W Engelmann which is called the action spectrum experiment. In this experiment when light passes through a prism it splits into its constituent colors splits into violet, indigo, blue, green, yellow, orange and red.
Aerobic bacteria require oxygen for their survival. The green algae produce oxygen during photosynthesis. Engelmann released aerobic bacteria to it. it is found that the bacteria accumulated at the blue and red light because photosynthesis and oxygen release were higher there. So, it establishes the relationship between the wavelength of light and photosynthesis.
What process is responsible for producing most of Earth's oxygen?
A.) photosynthesis
B.) respiration
Answer:
Photosynthesis

Answer:
Nutrient poor soil
Explanation:
Because rainforest have very poor infertile.The soil also contains Less organic.
Or for simple answers wet forest bad, dry and healthy forest is good.
The soil in rainforest are nutrient poor soil.
What is Soil?In soil science, a soil type is a taxonomic unit. A distinctive soil type is made up of all soils that have a certain set of well-defined features in common.
The phrase "soil type" refers to the study of soil classification, which is concerned with the orderly classification of soils. Every soil on the planet is a particular soil type.
Minerals, soil organic matter, living organisms, gas, and water are the five components that make up soil. Clay, silt, and sand are the three size classes for soil minerals.
The majority of soil types in hierarchical soil classification schemes are in the higher or intermediate level.
Therefore, The soil in rainforest are nutrient poor soil.

6. In a Bio 207 lab you determine that the cost of transport for two fish from different species is 1 kJ/km for fish one, and 10 kJ/km for fish two. Provide an estimate of the swimming speed of each fish assuming that a) both fish have the same metabolic rate; b) fish two has a metabolic rate 10 times higher than the metabolic rate of fish one; and c) fish one has a metabolic rate that is 100 times smaller than the metabolic rate of fish two. Note that the ratio of metabolic rate to speed defines the cost of transport in units of energy/distance.
Answer:
b) fish two has a metabolic rate 10 times higher than the metabolic rate of fish one.
Explanation:
The fish one covers 1 kilometer distance by using 1 kilo Joule of energy while on the other hand, fish two covers consumes 10 kilo Joules of energy for covering the same distance i.e. one kilometer. This means that fish two has a metabolic rate 10 times higher than the metabolic rate of fish one. This high metabolic rate may be due to the higher mass of the fish two which needs more energy for the movement to cover distance of one kilometer.
The elephants represented in lanes 3 and 5 could have been a match to the ivory sample if you failed to amplify one allele in either the ivory or the sample, so you cannot exclude these choices without running the experiment multiple times. On the other hand, you can definitely eliminate the elephants in lanes 1, 2, 4, and 6. Explain why.
About the question:
I failed to find the result of the PCR / electrophoresis. However, I will try to explain when to still consider a sample, and when to exclude it.
Answer:
Probably elephants 1, 2, 4, and 6 exposed a pattern of lines that differed in most alleles from the ivory´s pattern. So they were considered to be different and, hence, excluded. However, elephants 3 and 5 only were different in one allele, which might be due to the amplification failure. In these last situations, the experiment must be run again, and include many markers.
Explanation:
The genetic profile is the series of alleles, characteristic of each individual, concerning a series of DNA fragments.
Once genetic profiles are obtained by using PCR/electrophoresis, they must be subjected to interpretation. The researcher must compare profiles to find concordance between individuals or the lack of it.
In the exposed example, probably we have a profile of the ivory sample, and we need to find out to what individual or population it belongs to. So we need to compare the pattern of bands of the different lanes with the ivory´s pattern of bands.
In resumed terms, if the ivory´s patterns completely match with another lane pattern, then this is the individuals or population to whom it belongs the ivory. However, if they do not match, we need to exclude this individual.
But this is not as easy as it looks like. Sometimes it is difficult to interpret the results because bands are not so clear, and sometimes there are failures during amplification, as said before in the statement of the problem.
In these situations, what you need to do is look for the lanes that match the most with the ivory one and discard those that differ the most. These last patterns probably belong to a different animal or population, that why they can be excluded. Individuals suspected of being the same as the individual understudy or belonging to the same population, must be subducted to a repetition of the study. Also, the use of several markers in the study increases the matches chances.
So, in the exposed example, if the amplification fails in one allele, elephants 3 and 5 could be a match to the ivory sample, probably because all the other alleles do match. You can only exclude them if, after the experiment repetition, the involved allele is still different. On the other hand, you can eliminate the elephants 1, 2, 4, and 6 because their pattern bands are significantly different from the ivory´s patterns, so you do not even need to repeat the experiment.
