A convergent evolution is a phenomenon of independent evolution of similar traits in species that are in different lineages. These traits are called analogues structures. They are similar in form or function but were not present in the last common ancestor of those species. So, t<span>he appendages of cockroaches and turtles are analogues structures with the similar function - creeping movements, and they are the result of the convergent evolution.</span>
Root hair cells absorb minerals and water from the soil.
The water absorbed by the root hair cells passes through the plant in xylem tubes, to then reach the leaves. The energy from the sun is then used to convert water(H2O) into hydrogen (H) and oxygen(O2).
I hope this helps
B. and I get you the one who made up this question is dump -_-
Answer:
True
Explanation:
There are certain limitations associated with the Punnett Squares. They are not useful in case of complex genetic inheritance such as linkage between two genes. In case of linkages it becomes difficult to estimate the distribution of genotypes and phenotypes. For example in case of Nail-patella Syndrome and gene associated with blood group two genes lie on the same chromosome in close vicinity and hence there are high chances of inheritance of these traits in the offspring from the parent thereby causing random distribution of the two traits. This random distribution cannot be captured through punnet square.
The same problem is associated in case where a single gene is determined by multiple genes with graded effects of each gene.
Pollen....because cones are absent in angiosperms.....flowers are absent in gymno....and seeds are also absent in gymno sperm........so and is pollen !
