Hi! This is a triglyceride
Answer:
The correct answer is - sensory neurons → inter-neurons → motor neurons.
Explanation:
The nerve system receives a signal from the external change or stimuli and transmitted it to the spinal cord and brain. The transmission of the signals or information is carried by three different types of nerve cells: sensory neurons, interneurons, and motor neurons.
Sensory neurons receive the signal from the external stimuli and converting it to the electrical impulses. Interneurons are the associative neurons that establish the connection between sensory neurons and motor neurons. Motor neurons are the efferent nerves that carry the signal from interneurons and brainstem or spinal cord and transmit to the muscles.
Thus, the correct answer is - sensory neurons → inter-neurons → motor neurons.
Answer:
The mechanisms of transport across the cell membrane are as follow: 1- simple diffusion, 2- facilitated diffusion, 3- primary active transport and 4-secondary active transport
Explanation:
The cell membrane is a selectively permeable structure capable of transporting substances by different mechanisms. Simple diffusion is a type of passive transport (i.e. does not require energy) where non-polar molecules (e.g. O2, CO2) pass across the membrane by a process that does not require energy from the cell. Facilitated diffusion is another type of passive transport where larger polar molecules (e.g., glucose and amino acids) pass across the membrane by using specific transmembrane integral proteins. On the other hand, primary active transport is a type of active transport that uses chemical energy (e.g., ATP) to move substances such as metal ions (Na+, K+, Ca2+) across the cell membrane against their concentration gradient. Finally, secondary active transport is another type of active transport where transporter proteins are used to couple the movement of ions (e.g., H+ protons) down their electrochemical gradient to the transport of another ions/solutes against their concentration/ electrochemical gradient.
Answer: B) The experimental group tests to see if the presence of Balanus in some manner prevents Chthamalus from growing.
Explanation:
The most logical third step in Connell's experimental procedure, permitting him to either accept or reject his hypothesis of competitive exclusion is the experimental group tests to see if the presence of Balanus in some manner prevents Chthamalus from growing.
Balanus is a species of crustacean, as know as sea acorns, whereas Chthamalus is a species of barnacles that can easily be found in the northern hemisphere's coasts.
