<h2>Anterior-posterior orientation</h2>
Explanation:
Flatworms have an anterior-posterior orientation and as a result more coordinated and deliberate movement is established
- Flatworms also called Platyhelminthes are a phylum of relatively simple soft-bodied invertebrate animals
- They are the largest phylum of acoelomates and are found in marine,freshwater and even in some damp terrestrial environments
- Movement in some flatworms is controlled by longitudinal,circular and oblique layers of muscle
- Flatworms anterior end helps in moving towards their food while the posterior end ensures that these organisms walk away from irritants
Answer:
rarwfaction is when a rare fragment off something is discovered
Answer:
Explanation:
Genes with recombination frequencies(RF) of 50 assort independently and are not genetically links together but gene that have less than 50 RF are genetically linked.
The Linked genes included
a-d 12 c-e 26
a-g 4 d-g 8
b-c 10
b-e 18
Starting the order from the most tightly linked to the least
a-g 4, genetic distance is 4cM
d-g 8 genetic distance is 8cM
b-c 10 genetic distance is 10cM
a-d 12 genetic distance is 12cM
b-e 18 genetic distance is 18cM
c-e 26 genetic distance is 26cM
Bleaching of the coral reefs. This is caused from greenhouse gases in the atmosphere, a main cause for these gases are our vehicles we drive.
