Answer:
The best estimate of population density of this particular Octopus spieces is (TOTAL POPULATION OF THE OCTOPUS)/(TOTAL AREA OF LAND)
Population density = (15/6) Octopus per hectare
Explanation:
To estimate the population density of a spiece in a particular area of land, we count the total number of the specie in the area and divide the total number by the area of the sampling region.
Above, the marine ecologist counts the number of octopus in three different intertidal regions that are each two hectares. The octopus counts are 7, 2, and 6 respectively.
Therefore, the total number of Octopus is 7 + 2 + 6 making 15. The regions are 2 hectares each. Since there are three of the intertidal regions, the total area is 2 x 3(6 hectares).
Therefore, Population density = (15/6) Octopus per hectare
Trans fats or trans fatty acids are produced in an industrial process that adds hydrogen to liquid vegetable oils to make them more solid. It can be found in many foods – including fried foods like doughnuts, baked goods and in processed foods which has partially hydrogenated oils that is the primary dietary source of trans fat. The amount of trans fat can be determined in a particular packaged food by looking at the Nutrition Facts panel. It is one of the causes of heart attack. The trans fats level in non-heart attack patients is 84% of the level in heart attack patients.
Answer:
- fresh snow → 0.9
- soil → 0.2
- ocean (high-angle sun) → 0.05
- ocean (low-angle sun → 0.95
Explanation:
Albedo is the radiation reflected by the earth´s surface to the universe.
Albedo might be defined as a relation between reflected light from a particle and the incident light. It is the fraction of the incident radiation that is reflected by any object. If the surface is mostly clear and clean, most of the incident radiation is reflected. But if the surface is dark and rugose, most of the incident radiation is absorbed, and the temperature of the absorbing object will increase.
Albedo value is always inferior or equal to one and can be expressed as a percentage. The surface that reflects 100% of the incident light will have an albedo value = 1. But if the surface absorbs all the radiation and does not reflect any percentage, the albedo value = 0. Note: there is no real object that might reflect or absorb 100% of the incident radiation.
The importance of albedo is that it avoids high temperatures on the earth. There are many different surfaces with different albedo values. Global variations in albedo are natural processes due to exogenic and endogenic variations. But to these natural events, we must add all the variations caused by human beings´ actions, which increase greenhouse gases, decreasing albedo, and increasing global warming. The increase of greenhouse gases, such as CO₂, decreases albedo. The same occurs with atmospheric dust due to volcanic eruptions. Additional material interposes between the earth´s surface and the universe, decreasing the energy return to the universe.
- fresh snow → 0.9
- soil → 0.2
- ocean (high-angle sun) → 0.05
- ocean (low-angle sun → 0.95
A red shift means that the object is moving away from you.
The answer for the given question above would be NO. The Y chromosome does not contain the genes that are critical for an organism's survival. To analyze it,<span> females do not have the Y chromosome, and they are able to survive. Females chromosome is XX. Hope this answers your question.</span>
