Answer:
Sensation.
Explanation:
The sensory receptors are responsible for the detection of stimuli. The bottom up and top down control are the two important processing that helps in the introductions of sensory information in the body.
Sensation is the process by which the organisms detect the internal as well as external stimuli. The three main process that are involved in sensation are detection of stimuli from the environment, the change of stimuli in electrical signal and then received by the brain for further processing.
Thus, the correct answer is sensation.
False ⇒ Our cells (human cells) contain DNA!
The correct answer is: A. minus end; dynein
Microtubules are cytoskeletal fibers that have an important role in the intracellular transport (movement of vesicles within the cell) and in the mitotic spindle during mitosis. The plus end of the microtubules extend through the periphery of the cells while the minus ends are anchored within the centrosome.
Necessary proteins for the vesicle’s movement are motor proteins:
• kinesin which is positive end directed
• dynein which is negative end directed
So, beside vesicles these proteins are also involved in organelles’ transport in opposite directions through the cytoplasm.
Answer:
Community.
Explanation:
Community can be defined as a group of living organisms present in a particular area that show interactions with each other. For example, a forest having trees, under-growing shrubs, inhabited birds and animals, and rooted in ground (soil) that contains various fungi and bacteria represent a biological community.
Thus, the correct answer is option). community.
