The characteristic that does not apply to plants is prokaryotic cells.
The characteristic that does not apply to plants is prokaryotic cells. Plants have eukaryotic cells, which are more complex and contain a nucleus. Prokaryotic cells, on the other hand, are simpler and do not have a nucleus.
Plants are multicellular organisms with tissues, meaning they are made up of many cells that work together to perform various functions. They also have cell walls containing cellulose, which provide structural support.
Lastly, plants undergo sexual reproduction where male and female gametes combine to form offspring. This allows for genetic diversity and adaptation to different environments.

B. Nutrients are lost from the ecosystem when organisms die.
C. The conversion of food into growth by an organism is not very efficient.
D. Energy is recycled by the decomposers back to the producers.
There are no more than five species in an ecosystem due to the conversion of food into growth by an organism is not very efficient. Thus option C is correct.
The food chain is a linear cyclical event where the transfer of nutrient and energy occur from one organism to the other.
Trophic level is defined as the stages involve in food chain which start with producers, primary, secondary and tertiary consumers.
The major parts of food chain are the sun is the primary source of energy.
Secondly producers include autotrophs such as plants, phytoplankton, cyanobacteria represent first tropic level in a food chain.
Consumers includes herbivores, the primary consumers which eat plants, carnivores are animals which eat other animals, parasites that live on other organisms, others are scavengers eat dead decaying matter.
Decomposers integral part of food chain get energy from dead or waste organic material.

An action potential in a muscle cell is initiated by acetylcholine, which binds to receptors on the muscle cell membrane, causing depolarization. This triggers voltage-gated sodium channels to open, allowing sodium influx into the cell, which propagates the action potential. The action potential then leads to muscle contraction.
An action potential on a muscle cell is initiated through a complex sequence of events. First, a neurotransmitter called acetylcholine (ACh) is released from the motor neuron and binds to receptors on the muscle cell membrane or sarcolemma. This binding opens up a channel in the ACh receptor, allowing positively charged sodium ions to enter the muscle fiber.
This ion movement causes the muscle fiber to depolarize, or become less negative, changing the membrane potential. As the membrane depolarizes, another set of ion channels, the voltage-gated sodium channels, are activated and trigger an influx of more sodium ions into the muscle fiber.
This flooding of sodium ions propagates an action potential, or electrical signal, across the entire muscle cell membrane. This action potential then interacts with the sarcoplasmic reticulum to release calcium ions, leading to muscle contraction.

B. Sexual reproduction
C. Regeneration
D. Vegetative propagation
Answer:
A. Asexual reproduction
Explanation:
Because it requires only one cell.
However sexual reproduction require two cell for reproduction.
4.Of the controlled substances, which schedule of drugs is the average person most likely to have in their homes? How are the controlled substances in this group different from those in the other schedule levels?
If you are working as a forensic scientist and are given an unknown powder from a crime scene, what would you hope to find out about the powder?
If I am working as a forensic scientist and I am given an unknown powder, I would analyze this and hope to find out where did this belong.
You find that the unknown powder contains the illegal drug cocaine. If someone where to ask you to determine the purity of the substance, what would they mean? Why is purity important in crime investigations?
The purity of the substance would mean that how much of the main component of cocaine is present in this powder. Purity is important in crime investigations because it will help you determine how much of the main component is present in that substance, the main component is the active ingredient of that substance.

The schedule of drugs that is mostly present at home is antibiotics.
