Answer:
Flowers are derived evolutionary from modified <u>leaves</u>.
Explanation:
Flowers are modified leaves possessed only by the angiosperms, which are relatively late to appear in the fossil record. The flowering plants have long been assumed to have evolved from within the gymnosperms; according to the traditional morphological view, they are closely allied to the Gnetales.
Answer:
This disorder is caused by mutations in either of two different genes; one of these genes is linked to the DNA marker locus and the other gene is not.
Explanation:
A gene marker (also known as a molecular marker) is defined as a particular DNA sequence that has a specific physical location on a given chromosome. The gene markers are always physically linked with genes of interest, thereby they are useful for identifying patients affected by a given disease and/or a particular phenotypic trait. In this case, in the first study, genetic variation of the marker has been shown to be useful to map one <em>locus</em> that is associated with the disease phenotype. However, in the second study, a second <em>locus</em> that is not linked to the marker can segregate independently, thereby showing different results from the first study (in this case, it is imperative to develop a new genetic linkage analysis to discover genetic markers linked to the second gene, which is also responsible for the disease phenotype).
Answer:
A type of cell division that results in two cells having the same number of chromosomes as the parent nucleus.
Explanation:
Typical for ordinary tissue growth.
The most likely reason for the scientists to count different numbers of redd is the observer’s efficiency.
Explanation:
In a field survey based on visual counting for visual stock assessment, the scientists may count a different number of redds each time in the same area due to the observer’s or the scientist’s efficiency.
The same place may first appear as redd and then later may not and accordingly the scientist's count also varies.
This error happens due observer’s inexperience in surveying, misidentification of redd species, changes or variations each time in the redd habitat, survey life, characteristics, spawning shifts etc., and poor temporal and spatial coverage.
Cell division is when a cell under goes mitosis. Which divides in top to create another cell of the same kind.
In Gamete a haploid germ of either sex unites with the opposite sex to have sex and have a zygote.
