Answer:
Bioaccumulation is the process by which toxins enter the food web by building up in individual organisms, while biomagnification is the process by which toxins are passed from one trophic level to the next (and thereby increase in concentration) within a food web.
I hope i helped you :)
Answer:
the gene for yellow body and the gene for forked bristles
Explanation:
The two genes that will have the highest recombination frequency are the gene for yellow body and the gene for forked bristles.
<em>Gene recombination refers to the exchange of genetic materials between different gene-containing regions (loci) on the same chromosome or between two or more independent chromosomes. A linkage map shows the frequency of recombination between genes.</em>
Generally, on a linkage map, when two loci are close to one another on the same chromosome, the frequency of recombination of the genes would be less than that of two loci that are further apart. In other words, the closer the loci, the lower the frequency of gene recombination and vice versa.
<em>In this case, the distance between the genes for yellow body and tan body is 27.5 map units, yellow body and sable body is 43 map units, yellow body and forked bristles is 56.7 map units. </em><u><em>The genes for yellow and forked bristles are the furthest to each other with 66.7 map units and, as such, will have the highest recombination frequency. </em></u>
Answer:
1) Accommodation is the process of changing the shape of the lens to focus on near or distant objects.
- <em>To focus on a near object</em> – the lens becomes thicker, this allows the light rays to refract (bend) more strongly.
- <em>To focus on a distant object </em>– the lens is pulled thin, this allows the light rays to refract slightly.
2) - i don't know. im so sorry -
(1)
Troposphere – This is the densest layer and where weather events occur
Stratosphere – This is where the ozone layer is found. Some high altitude aircraft cruise in this layer.
Mesosphere – Temperatures drop with altitude in this layer
Thermosphere – This is where most of the meteorites that enter the earth’s atmosphere burn up. This layer takes up most of the Uv and X-rays from the sun. Most satellites orbiting earth are in this layer
Exosphere – almost akin to space due to the thinness of the layer. Molecules in the layer often escape into space
(2)
A ‘pause’ is a transition between the above-mentioned distinct layers. The tropopause, for example, occurs between the troposphere and the stratosphere and the stratopause between the stratosphere and mesosphere and thermopause is found between thermosphere and exosphere.
(3)
A temperature inversion is a rise in temperatures with altitude in a layer in the atmosphere. One layer exhibiting temperature inversion is the stratosphere. This is due to the ozone layer that absorbs UV light. The upper ozone absorbs most of the UV light, than lower ozone, exciting the molecules and making the higher altitudes in the layer to be warmer.
(4)
The ozone layer protects life on earth from the high energy UV radiation from the sun. UV is capable of causing double-stranded break on DNA resulting in genetic mutations on organisms. Most of these would be lethal. The Ozone absorbs most of the UV before it reaches earth's surface. Ozone is formed when an oxygen molecule reacts with another oxygen atom to form an O₃. The oxygen atoms are made from the splitting of an oxygen molecule by UV light.
