Answer:
The macronucleus is the centrer of all metabolic activities of the organism.
Explanation:
<u>Answer</u> :- Step 1 Receptors (sense organs, muscles, glands, etc.) receive stimuli from the environment or from inside your body.
Step 2 The central nervous system processes information received from the peripheral nervous system.
Step 3 The central nervous system sends out the processed information to the peripheral nervous system.
Step 4 The peripheral nervous system sends a message to the body part that needs to respond so you can react appropriately to the stimulus.
<u>Explanation</u>:-
- There are two different parts of the nervous sytem-the peripheral nervous system (PNS) and the central nervous sytem (CNS).
- The <em>CNS</em> consists of the brain and the spinal cord .
- The <em>PNS</em> consists of all the nerves that lie outside the CNS.
- The main function of the PNS is to gather information from the <em>sensory receptors</em> located in our body and convey this information to the central nervous system.
- The CNS collects this information from the PNS and then interprets it. The interpreted information is then relayed back to the body parts via the PNS to perform the appropriate action.
Answer:
Cohesion and adhesion of water molecules
Explanation:
Cohesion has to do with the ability of water to adhere together .
The cohesive properties of water which is occasioned by hydrogen bonding between adjacent water molecules allow the column of water to move up through the plant irrespective of the force of gravity as water molecules are evaporating at the leaf surface.
The adhesive properties of water, which means, the attraction between the water molecule and the xylem wall also ensure continuity in the movement of the water column in the xylem.
Hence the cohesive and adhesive properties of water molecules are important for transpiration to occur.
1. True: asexual allows for rapid reproduction
2. False: increases genetic variation in a population
3. False: sexual reproduction creates more genetic variation
4. True: during meiosis, the genes can combine differently. See punnet squares and genetics (Mendel's pea study)
