The answer would be B. :)
Answer:
DNA strand = complementary strand
GCAAG = CGTTC
TTACG = AATGC
GATAC = CTATG
CGGAT = GCCTA
DNA strand = mRNA strand
CGATT = GCUAA
GCTTA = CGAAU
GCATC = CGUAG
TTCAT = AAGUA
Explanation: A complementary strand is not the same in base composition and sequence with the template strand. In DNA, anywhere adenine is found in the template strand, thymine is found in the complementary strand and anywhere cytosine is found in the template strand, guanine is found in the complementary strand. But in RNA, anywhere adenine occurs in the DNA template strand, uracil occurs in the mRNA strand, wherever thymine occurs in the DNA template strand, adenine occurs in the mRNA strand and wherever guanine occurs in the DNA template strand, cytosine occurs in the mRNA strand.
Summarily, in DNA adenine pairs with thymine while cytosine pairs with guanine while in mRNA, adenine pairs with uracil, while cytosine pairs with guanine.
Answer:
This study was focused on an Ecosystem level, as it involved soil properties and above-ground vegetation interacting with mentioned soil physic properties.
Explanation:
Ecological studies can be performed at different hierarchy levels:
- <u>Organism</u>: This is an individual physiologically independent from other individuals. At this level, it must be understood <em>how an organism survives</em> under certain changing <em>physic and chemistry conditions</em>, and how it <em>behaves</em> to reproduce, avoid predators, and find food.
- <u>Population</u>: Groups of individuals from the same species, with similar characteristics, capable of crossing, leaving offspring that live in the same habitat at the same time. At this level, it is interesting to know the <em>size of the population required to leave fertile offspring</em> that ensure the population will <em>survive over time</em>. It is also interesting to know <em>genetic variability </em>that allows <em>evolutive adaptation </em>to environmental changes.
- <u>Community</u>: Relationship or interaction between different species groups that live in the same habitat and at the same time. At this level, it is interesting to study <em>inter-specific interactions</em> that could cause <em>changes in the populations´ size</em>. These could be the cases of competition, predation, parasitism, mutualism, and etcetera.
- <u>Ecosystem</u>: Basic interaction unit between population and environment that turn in complex relations existing between living and non-living elements in a given area. In the example, interactions between recovering vegetation and soil properties, as non-living elements.
A daughter cell that matures to the inside of the vascular cambium becomes<u> secondary xylem</u> and a daughter cell that matures to the outside of the vascular cambium becomes <u>secondary phloem.</u>
<u />
- The cambium divides its cells to create secondary xylem and phloem. As secondary phloem and xylem tissue builds up, the stem becomes thicker and develops wood and bark.
- The kind of xylem produced by secondary growth is known as secondary xylem. In contrast, during primary growth, the primary xylem develops.
- As a result, lateral growth, as opposed to vertical growth, is connected with the secondary xylem, as opposed to the primary xylem.
- The procambium, which is found between the xylem axis and the phloem pole, develops into the cambium in the root.
- A pattern resembling the arrangement of secondary stem is produced when xylem forms in the core and phloem on the perimeter of secondary development.
