Answer:
CENTROMERE
Explanation:
The CENTROMERE is the primary constriction region where the identical DNA molecules are most tightly bonded to each other during mitosis and meiosis.
The typical chromosome in metaphase is composed of two sister chromatids joined by the centromere.
Surrounding the centromere, we can find the kinetochores. These are laminar proteinic structures forming a plate where the spindle and kinetochore fibers will join during chromatids separation.
The position of the centromere defines the chromosomes as acrocentric, metacentric, or submetacentric.
Answer:
Santi is walking barefoot through his yard when he steps on a sharp rock. The skin on the bottom of his foot sends this information through a(n) <em>sensory</em> neuron to his CNS. A(n) <em>interneuron</em> picks up this information and carries it to <em>motor neurons of the CNS</em>, which sends a signal to the muscles in his foot causing his foot to pull away from the rock.
Explanation:
The scenarios discussed in the question is known as a reflex action. In this action, specific receptors detect specific stimuli. For example, pain in the barefoot due to steeping on a sharp rock was the stimuli. This stimulus was detected by the sensory neurons. The sensory neurons turned this information into a chemical signal which was transported by the interneurons to the motor neurons of the CNS. The CNS detected the signal and gave information for a response as a result of which Santi pulled back his feet.
Answer:
Humans have destroyed and modified various locations, such as forests, jungles, oceans. They begin to modify an environment in order to build new infrastructures, like buildings, factories, or even communities.
Explanation:
The reason for this is because they want to get as much resources for economic purposes, like for example mines, touristic places, factories. At first, this interaction affects the environment more, because of the loss of species or resources due to the human activity. Then, after this, it will affect the human, because of the lack of resources and global contamination caused by the environment being destroyed or modified.
