Neurotransmitter
100

This green pigment found in plants' chloroplasts is essential for photosynthesis.

Chlorophyll

100

These cells transmit electrical impulses and are the basic units of the nervous system.

Neurons

100

 This term refers to the molecule that binds specifically to a receptor to initiate a signaling cascade.

Ligands

100

This is the first phase of mitosis where chromosomes become visible and the nuclear membrane starts to break down.

Prophase

100

It is the general name for chemicals that transmit signals across a synapse between neurons.

Neurotransmitters

200

He is known as the father of evolution for his theory of natural selection, published in "On the Origin of Species."

Charles Darwin

200

This term refers to the physical expression of an organism's genetic makeup

Phenotype

200

This type of enzyme adds phosphate groups to proteins and is often involved in activating signaling pathways.

Kinase

200

After mitosis, this process divides the cytoplasm, creating two daughter cells.

Cytokinesis

200

This neurotransmitter is involved in reward, motivation, and motor control, and its imbalance is linked to Parkinson's disease.

Dopamine

300

This class of animals is characterized by having hair or fur, producing milk, and giving live birth.

Mammals

300

This largest organ in the human body serves as a barrier against infections and helps regulate temperature.

Skin

300

This is the process of passing a signal through a cell to create a response.

Signal transduction

300

This structure made of microtubules helps pull apart chromosomes during mitosis.

Mitotic spindle

300

This neurotransmitter affects mood, sleep, and appetite, and is commonly associated with depression and anxiety.

Serotonin

400

These are the building blocks of DNA, consisting of a phosphate group, a sugar, and a nitrogenous base.

Nucleotides

400

This term refers to the role or position an organism has in its environment, including its behavior and interactions.

Niche

400

This molecule, called cAMP, helps carry signals inside a cell after a receptor is activated.

cyclic AMP

400

Mitosis happens in this type of body cell, not in reproductive cells.

Somatic cells

400

This neurotransmitter is crucial for muscle contraction and plays a key role in memory and learning.

Acetylcholine

500

In this type of asexual reproduction, a single-celled organism divides into two identical daughter cells.

Binary fission

500

These tiny organisms, which can be bacteria, viruses, or fungi, are responsible for causing infections.

Pathogens

500

This enzyme removes phosphate groups from proteins to turn off signals.

Phosphatase

500

Before mitosis begins, the cell spends most of its time in this phase, growing and copying its DNA.

Interphase

500

This inhibitory neurotransmitter reduces neural activity and helps to calm the brain, often associated with reducing anxiety.

GABA (gamma-aminobutyric acid)
