Answer:
C
Explanation:
Ribosomes are organelles which produce protein inside a cell. They do the same even if they are on an ER membrane.
Hope this helps! :)
Answer :3. similarities among vertebrate forelimbs suggest that they evolved from a common ancestor.
Explanation:
The study of differences and similarities in the anatomy of different species is comparative anatomy. It is based on the concept that
1.)Homologous structures which are present in different species, because they have a common decent and must have evolved divergently from a shared ancestor. Theses anatomic structures may not be used for the same purposes. For example the forelimb of fox and whale.
2. Some structures (Analogous)which are similar in different organisms must have evolved ,(acquired through natural selection) through convergent evolution in similar environment, and not inherited from a recent ancestor. These organisms usually use these structures for a common purpose. For example the streamline body shape of shark and porpoises, which though are used for a common purpose of swimming, were inherited from different ancestors.
. Example of comparative anatomy is the common bone structures in forelimbs of fox, whales, bats, and humans. These appendages is made up of the same basic parts; despite serving different functions.
Comparative anatomy helps scientists in classification of organisms based on their similar characteristics of their anatomical structures.
D. The populations are in same areas but differ in population size.
Good luck! :)
The brain is divided into lobes that carry out different kinds of functions. There are 5 lobes in the brain:
1. Frontal lobe: Concentration, planning, problem solving, etc are the function performed by this region of the human brain.
2. Parietal lobe: Touch, pressure, taste and body awareness is processed by this lobe.
3. Temporal lobe: Long-term memory, hearing, emotions are processed in this lobe.
4. Occipital lobe: Sight is processed in this lobe.
5. Cerebellum: Coordination and balance, fine motor control are performed by this part of the brain.
The modern neuroscience has also confirmed the presence of brain waves like the alpha, beta, theta and gamma rhythm that sweep across the different lobes and regions of the brain. These waves are known to result from the collective activity of neurons in each of the regions. The brain waves are studied to check the activity of the regions that are coordinating together to carry out a particular type of task.
