Answer:
Large molecules made up of many small organic molecules that are often referred to as monomers. Macromolecules are polymers of monomers.
sorry if I am wrong
Answer:
1. When a rubbed ruler is brought close to the paper, salt and pepper they are not equally attracted as paper is lighter than pepper and salt, so it takes less effort for paper to overcome the force of gravity.
2. electrostatic induction is a phenomenon in which static electricity is generated in an object by bringing an electrically charged object near it. When a charged object is brought near to an uncharged body it causes electrical charges to redistribute in the body, resulting one side having excess of positive charges and other side having negative charges, as a result body become charged. Electrostatic interaction also depends upon the nature and mass of body.
b. the combination of fur cloth and rubbed ruler produce greatest effect. The reason is that when ruler is brought near to fur excess of electron will flow into fur.
The last one (d) I think it is the correct one
The central nervous system (CNS) and effector organs receive messages from receptors through the nerve cells, respectively.
<h3>What do neuron and muscle cells have in common?</h3>
- Tissues are made up of both nerve and muscle cells. Both mitochondria and endoplasmic reticulum are found in muscle and nerve cells. The body's operations are coordinated through the cooperation of muscle and nerve cells.
- Neurons, a type of nerve cell, and muscle cells are significantly distinct from one another. While nerve cells transmit signals from receptor cells to either glandular cells or muscle cells, or both, in order to move the body, muscle cells (myocytes) contract to cause movement.
- The synapse is the point at which a nerve cell can communicate with another cell or muscle cell. The space between the pre-and postsynaptic cell membranes is known as the synaptic cleft.
The function of muscle cells:
The same genetic material can be used to correctly fill in the first blank, and to contract can be used to correctly fill in the second blank.
The genetic material is present in all of the body's cells, including blood, muscle, neuron, and cardiac cells. Cell differentiation causes them to specialize into different types of cells.
Muscle cells' purpose is to contract, which aids in movement and mobility. Skeletal muscles aid in movement and smooth muscles support the operation of interior organs like the uterus, whose contractions aid in childbirth.

Answer:
The correct answer is "Decreased metabolic rate".
Explanation:
The sympathetic division is the part of the autonomic nervous system that deals with the coined "fight or flight" response when facing with a stressful situation. Is not true that when the sympathetic division is activated the metabolic rate decreases, actually, the effect is the opposite. The sympathetic division influences key processes such as glucose and lipid metabolism as well as daily energy expenditure, particularly, it influences the resting metabolic rate (RMR).
