Answer:
The simplest method of propagating a tree vegetatively is rooting or taking cuttings. A cutting (usually a piece of stem of the parent plant) is cut off and stuck into soil.
Remove any flowers or fruit on the cutting. Trim the stem to just below where the bottom most leaf meets the stem. On each of the leaves on the stem, cut off half of the leaf. Put the end to be rooted.
Answer:
scientific consensus changed as scientists learned more about organisms.
Explanation:
The classification system for organisms has changed from seven levels to eight level of classification system because scientists learned more about organisms. This new learned information allow scientists to change the existing classification system. When the scientist find new species that may have to change classification systems in order to accommodate them and placed them accurately in the classification system.
Answer:
1. FtsZ tubulin homolog
2. actin and tubulin
3. actin and tubulin
4. b. animals and bacteria
Explanation:
1. In bacteria, the binary fission process takes place when the cytoskeletal structure of the bacteria are assembled to form the contractile ring in the centre of the cell. The contractile ring in bacteria is composed of the Z-protein which is a tubulin homolog.
2. Plants: the plants divide by the cell plate formation and not the contractile ring formation. This is mediated by the actin, tubulin and vesicle produced from the dictyosomes.
3. Animals: a contractile ring attached to the plasma membrane is formed which is composed of the F-actin and tubulin.
4. Since the bacteria and animal cytokinesis involves the formation of the contractile ring and thus the same mechanism of cytokinesis.
Answer:
There are no options to this question, however, the question can be answered. The answer is:
FF and FF/Ff
Explanation:
This question involves a single gene coding for possession or not of freckles in humans. The allele for freckles (F) is dominant over the allele for no freckles (f). This means that genotypes FF and Ff (heterozygous) will possess freckles while only genotype ff will not.
According to this question, a couple has several children in which all of the children have freckles i.e. have either genotype FF or Ff. This is as a result of the fact that the parent's genotypes were either FF or Ff. That is, one parent is FF while the other is either FF or Ff. This genotypes will only produce children with freckles.
Hi!
It would be 1, because the white fur is a form of camouflage.
Hope this helps!
