Answer:
True.
Explanation:
The interference theory explains the memory of the human brain. These memories are long term memories. Two main types of interference are proactive interference and retroactive interference.
The retroactive interference means when the older memories vanishes due to the learning of the new memory. The previously learned memories are forgotten by the individual. The same thing has happened with Mimi as she forgot the previous recipe due to the new memory.
Thus, the answer is true.
Answer:
Option D = 3.4 g/mL
Explanation:
Given data:
Volume of water = 21.2 mL
Volume of water + object = 27.8 mL
Mass of object = 22.4 g
Density of object = ?
Solution:
First of all we will calculate the volume of object.
Volume of object = Volume of water+ object - volume of water
Volume of object = 27.8 mL - 21.2 mL
Volume of object = 6.6 mL
Density of object:
d = m/v
d = 22.4 g/ 6.6 mL
d = 3.4 g/mL
A motor unit consists of <u>a single motor neuron</u>.
<h3>What is a motor unit?</h3>
Most mature extrafusal skeletal muscle fibers in mammals are innervated by only a single alpha motor neuron. Since there are more muscle fibers by far than motor neurons, individual motor axons branch within muscles to synapse on many different fibers that are typically distributed over a relatively wide area within the muscle, presumably to ensure that the contractile force of the motor unit is spread evenly .
In addition, this arrangement reduces the chance that damage to one or a few alpha motor neurons will significantly alter a muscle's action. Because an action potential generated by a motor neuron normally brings to threshold all of the muscle fibers it contacts, a single alpha motor neuron and its associated muscle fibers together constitute the smallest unit of force that can be activated to produce movement.
Sherrington was the first to recognize this fundamental relationship between an alpha motor neuron and the muscle fibers it innervates, for which he coined the term motor unit.

The injury from machinery is a hazard of commercial fishing.
<h3>What does commercial fishing mean?</h3>
Commercial fishing is the activity of catching fish and other seafood for profit, particularly among wild species. It supplies a large amount of food around the world, but those who practice it as an industry sometimes look for long conditions from the ocean's limits, in adversaries.
If any damage to machinery occurs, it will end commercial fishing, causing deaths and oil in the seas.
