Cell Signaling
This type of signaling occurs when a cell releases a signal molecule into the bloodstream, affecting distant cells.
What is endocrine signaling?
This type of structure, found in different species, indicates common ancestry due to its similar structure but different function.
What are homologous structures?
This phase in the cell cycle is where the cell spends most of its life, performing normal functions and preparing for division.
This pigment is primarily responsible for capturing light energy in plants.
What is chlorophyll?
What is the largest organ found on the human body?
What is the skin?
This enzyme is activated by cAMP and plays a crucial role in the signal transduction pathway of many hormones.
What is protein kinase A?
What are vestigial structures?
This phase of interphase involves the replication of DNA.
What is the S phase?
This organelle is where photosynthesis takes place in plant cells.
What is the chloroplast?
The grouping of gases on the periodic table of elements that are odorless, colorless, nonflammable, and monotonic that have low chemical reactivity.
What are the noble gases?
What is a receptor?
This scientist is famous for his theory of natural selection. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science.
Who is Charles Darwin?
This phase of the cell cycle includes the actual division of the cell's cytoplasm.
What is cytokinesis?
These clusters of pigments and proteins in the thylakoid membrane are involved in the light reactions.
What are photosystems?
The correct order biological classification is the following:
What is domain, kingdom, phylum, class, order, family, genus, species?
This type of receptor changes shape when a ligand binds, allowing ions to flow across the membrane.
What is an ion channel receptor?
This mechanism of evolution involves random changes in allele frequencies, especially in small populations.
What is genetic drift?
This gene makes a protein that is found inside the nucleus of cells and plays a key role in controlling cell division and cell death.
What is p53?
This is the first stage of cellular respiration, occurring in the cytoplasm and breaking down glucose into pyruvate.
What is glycolysis?
Where are the 3 smallest bones in the human body located?
What is the middle ear?
What are secondary messengers?
This concept states that allele frequencies in a population will remain constant in the absence of evolutionary influences.
What is the Hardy-Weinberg principle?
This process involved programmed cell death and is crucial for eliminating damaged or unnecessary cells.
What is apoptosis?
This series of protein complexes in the inner mitochondrial membrane transfers electrons and pumps protons to create a proton gradient.
What is the electron transport chain?
This is the exact number of bones in the adult human skeleton.
What is 206 bones?
