Annelida are segmented warms that developed a straight and complete digestive system, and close circulatory system. The statement is TRUE.
Annelida are the segmented warms than has been include terrestrial and the aquatic species. They characterize for the having their bodies segmented into equal parts linearly arranged along the anteroposterior ax.
Their digestive system has the straight, going from the mouse in the anterior region to the anus in the posterior region. It has been located in the center of the coelom, being held by the septums. Digestion has the extracellular. Excretion is done through nephridium.
Annelida have the well-developed closed circulatory system, in which the blood remains and the flows in vessels. The statement Members of phylum annelida have a closed circulatory system and a complete digestive system is TRUE.

Answer:
Pollen from a yellow daisy travels across a stream and pollinates an orange daisy.
Explanation:
Gene flow refers to the movement of genes from one population to another population of the same kind.
From the alternatives given, Pollen movement from a yellow daisy across a stream to pollinate an orange daisy is an example of gene flow
Answer: Pollen from a yellow daisy travels across a stream and pollinates an orange daisy.
Explanation:
The gene flow can be define as the transfer of the genetic variation typically from one population to the other. If the rate of flow of gene is high enough, the two population in which the gene flow has occurred will become equivalent in allele frequencies and therefore will become the single population.
Pollen from a yellow daisy travels across a stream and pollinates an orange daisy. is the correct option, this is because of the fact that through pollen which is the male gamete the genetic variations are passing from one population to another population of the same species of daisy. Thus the allelic frequencies will become the equivalent in the two populations of the same species. Thus this will result in the formation of the single population.

Explanation:
Oil control rings are designed differently than compression rings. A typical oil control ring consists of three separate pieces: two very thin metal rings called scrapers, and a spacer ring called an expander placed in the groove between them.
