The correct answer is option D, that is, genetic diversity among the species.
The sum of genetic characteristics in the genetic makeup of a species is known as genetic diversity. It is differentiated from genetic variability that illustrates the capability of genetic features to change.
The genetic diversity functions as a medium for the populations to amend with the fluctuating environments. With more changes, there is more possibility that some individuals in a population will exhibit different forms of alleles, which are appropriate for the surrounding.
These individuals hold high possibilities of survival in order to generate offspring exhibiting that allele. The population will continue for more generations due to the accomplishment of these individuals.
Archaeopteryx was a DINOSAUR.
Formerly, Archaeoptery was classified as an early bird, but it was later re-classified as a dinosaur because it shares more similarity with the dinosaurs. Scientists have not really reach a consensus about this classification.
Archaeoptery was re-classify as a dinosaur because it share many anatomical structure with coelurosaurs which are a group of carnivorous dinosaurs.
<u>Answer:</u>
If calcium were removed from the tissue then the polarity will be established within the cell but polarity will be lost in the tissue.
<u>Explanation:</u>
- Cell polarity is the cellular components like cytoplasm, plasma membranes and other various cell organelles in the asymmetric order.
- The coordinated arrangement of this cell polarity in tissue plane is called as planar cell polarity (PCP).
- Calcium is the major component in the tissues that helps in formation of bones and other parts of body, if it is removed then the polarity will not be seen in the tissue, but in the cell the polarity will be established.
Answer:
The technique is known as "staining"
Explanation:
Staining is a technique used to enhance the color contrast of the microscopic samples when observed in the microscope especially in the microbiological samples.
In the given question, when the staining technique is used to identify the sample then staining procedure is followed in a process where the samples can be identified on the basis of the color contrast which is in the case of gram staining.
The gram staining is used to identify the bacteria on the basis of color as the bacteria which appear blue in color are called gram-positive and the bacteria which appear red in color are gram-negative bacteria.
Thus, staining is the correct answer.
In an animal cell, DNA is found in the greatest concentration in the Nucleus.
