Explanation:
When a person opens the door, he or she uses 3 systems:
1. Nervous system: from the nervous system, neural instructions are generated through electrical impulses towards the muscles of the upper limb so that they make the necessary movements to open the door.
2. Muscular system: through the muscles of the trunk and the upper limb, it generates voluntary movement to open the door.
3. Skeletal system: the bones are the support of the soft tissues and the fulcrum of most of the skeletal muscles. In this sense, it serves as a support for the muscles of the trunk and the upper limb to carry out the movement of opening the door.
we can conclude that the correct answer is:
Answer:
1. Nervous system: instructions are generated from the nervous system by means of electrical impulses towards the muscles of the upper limb so that they carry out the necessary movements to open the door.
2. Muscular system: the muscles of the trunk and the upper limb generate voluntary movement to open the door.
3. Skeletal system: it supports the muscles of the trunk and the upper limb to carry out the door opening movement. It also has joints that help the mechanical movements necessary to open the door.
There is no defined limit on the capacity of the brain. The brain's capacity cannot be measured as it is not subject to a defined "space" where the memory is kept, and it is not such that each neuron is responsible for a single memory. The brain has complex mechanisms of memory storage, that even improve if trained.
Answer:
A. They have the same function
B. They have evolved independently
C. They indicate an evolutionary relationship
Explanation:
- Analogous structures are structures with a different embryonic but have evolved to perform similar function.
- <em><u>Analogous structures are a result of convergent evolution which is the independent evolution of similar features in species of different lineages or different embryonic origin.</u></em>
- Examples of analogous structures include; wings in flying animals like bats, birds, and insects, and fins in animals like penguins and fish.
Elephants, who are important grazers, are instrumental in transforming woodlands into grasslands. This has a tremendous impact on other species that depend on the grass for their survival. The significance of the elephant in this example is B. keystone species.
