Answer:a. Retention of five functional digits on the tore and hindimbs
Explanation:
The presence of five digits or pentadactyly on the fingers as well as on the toes makes the primates distinct from other mammals. Also the keratin nails are present on each digit makes these organisms distinct from other mammals.
The five digits on the hindlimbs helps in grip of objects and on toes helps in climbing.
Animal cells are a usual example of a eukaryotic cell, enveloped by a plasma membrane, and comprising a membrane-bound nucleus and organelles. Like the cells of plants and fungi, they do not exhibit cell wall.
The labeling in the mentioned diagram is:
A. Rough endoplasmic reticulum
B. Cytoplasm
C. Smooth endoplasmic reticulum
D. Nucleolus
E. Nucleus
F. Mitochondria
G. Golgi apparatus
H. Lysosome
I. Plasma membrane
The Golgi apparatus functions closely with the rough endoplasmic reticulum. When a protein is formed in the rough endoplasmic reticulum, then the formation of transition vesicle takes place. This vesicle or sac floats via the cytoplasm to the Golgi apparatus and is then absorbed. From there, the vesicle travels to the membrane of the cell and the molecules are then discharged out of the cell.
Answer:
I think that birds have different bill lengths because of their habitats and their diet. Also natural selection and evolution has also played a factor due to the fact that birds have not always looked the way that they do now, for example the Archaeopteryx a bird that lived around the time of the dinosaurs had a shorter and more powerful bill to grind insects and small mammals
