Dust and many other particles gathered up and formed around by a gravitational pull.
Protects, helps thermoregulate, provides sense of touch, helps remove waste
The directed movement of substances, into, out of or within a cell, either in a vascular tissue or in the vascular membrane.
The main roles of plant stems and roots are to transport substances around the plant. They have two types of transport systems – xylem and phloem . Xylem transports water and minerals. Phloem transports sugars and amino acids dissolved in water.
hope it helps because there is not any issue of transport , and if my answer i s not supportable comment i will provid emore information.
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.
