Muscle tissue is responsible for both voluntary and involuntary movements.
Answer:
The main difference between prophase I and II is that during prophase 1, the pairing of homologous chromosomes or the synapsis allows the non sister chromatids to cross over at chiasmata, leading to genetic recombination between chromosomes. During prophase II,synapsis does not occur; hence, no genetic recombination takes place between the chromosomes
During Prophase I the Centrosome is duplicated during the interphase, which is a process prior to prophase while in Prophase II, the Centrosome is duplicated during the prophase II due to the lack of an interphase.
D. A section of DNA that codes for a Specific trait
Model two because it includes more organelles
Answer: creating an ozone layer to shield life from UV rays
Cynobacteria or blue green algae is the strain of bacteria, which was able to produce oxygen in the primitive earth as a result of photosynthesis. The abundance of oxygen in the atmosphere formed the ozone layer in the upper atmospheric layers, these layers are protective enough to provide a shield against the harmful UV radiations incident on earth coming from the sun.
