Answer:
a. transcription
Explanation:
<em>Sugar transport in phloem is referred to as pressure flow and it involves the movement of sugar through the phloem vascular tissue from the regions where sugar is synthesized (by photosynthesis) to other parts of the plant's body that require sugar.</em>
The parts of plants where sugar is synthesized (usually the leaf) is known as sugar source while the parts where they are transported is referred to as the source. Sources are usually areas of of high osmotic concentration and high water pressure while sinks are usually areas of low osmotic concentration and low water pressure.
<em>Hence, sugar transport in the phloem can be said to be influenced by the rate of sugar production at the source (rate of photosynthesis), turgor pressure as well as sugar concentration in sinks and sources.</em>
The only option that has no known effect on sugar transport in the phloem is transcription.
The correct option is a.
<span>The correct answer is "Absorption of rainfall by soil."
The hyrdosphere refers to all water on the earth's surface. The geosphere, in this context, refers to the solid parts of the earth (rocks, sand, etc.) Since rain is part of the hydrosphere and soil is part of the geosphere, rain soaking into the soil would be an interaction between the two. The other choices deal with changes in the hyrdrosphere, but there is no interaction with the geosphere.</span>
There are dominant and recessive alleles. when one allele from each parent combine, there are a couple different possibilities for traits. for example, whenever a parent gives off a dominant allele, you will automatically have that trait because it would have combined with another dominant allele, or it would have overpowered the other recessive alelle. you cam find these different combos by using a punnet square. but also, some traits, such as eyecolor, are determined by incomplete dominance, when the colors of your parents in their greenness combine in to a new color. or, you can have codominance when you have one of each eyecolor of your parents.
Answer:
In terms of the giraffeexample, Darwin's theory of evolution through natural selection wouldsuggest that a giraffewas born with a longer neck by random chance. ... Having access to more food allowed the giraffe to live longer and reproduce more, ultimately leading to more long-neck giraffes.
