Answer:
There are many types of evidence which support the theory of evolution such as comparative anatomy, fossil records, phylogenetic relationship, embryology et cetera
Comparative anatomy includes homologous organs and analogous organs. They support divergent and convergent evolution respectively.
For example, the homologous structure of limb of humans, birds, bat, horse, whale et cetera show that they are made up of the same set of bones which are humerus, radius, ulna, carpals, metacarpals, and phalanges.
It shows divergent evolution and supports that these organisms have evolved from a common ancestor.
Embryological evidence: When early stages of embryological development of different organisms are compared, it is found that these stages are similar at different levels of development.
For example:
- The appearance of pharyngeal-arch (gill-like structures) in vertebrates during embryo development.
- Salamanders and terrestrial frogs pass through larval stages within an egg. They possess the features similar to aquatic larvae, however, when they hatched out the eggs being ready for life on land.
The genotype that will be given is going to big r and small r because the cross will be the same.
An annulus is the ring-like structure found on the stipe of some species or mushrooms. This represents the remaining part of the partial veil, after it has been ruptured to expose the gills or other pore producing surface. As its function is to disperse the spores.
Answer:
Internal Cycling
Explanation:
Internal cycling starts when the nutrients transform into ecosystems. The plants through their roots take the necessary ingredients and built them in the tissues. When tissues grow, the nutrients go back to the ground in the form of dead organic matter.
Microbes transform the organic nutrients into minerals, which are again available to the plants.
The blood electrolytes—sodium, potassium, chloride, and bicarbonate—help regulate nerve and muscle function and maintain acid-base balance and water balance. ... Thus, the kidneys help maintain a balance between daily consumption and excretion of electrolytes and water.
