Skeletal Muscle
Ans: This muscle cell is striated, long, and cylindrical. There are many nuclei in a skeletal muscle cell.
Attached to bones in the body, skeletal muscle contracts voluntarily, meaning that it is under conscious
control.
Qiz Smooth Muscle
Ans: nonstriated musle cell that are spindle-shaped. contains one nucleus. Found in the walls of inyernal
organs like the bladder and stomach. Smooth muscle contraction is
INVOLUNTARY and controlled by the autonomic nervous system.
Qiz Cardiac Muscle
Ans: Muscle cells that are striated,short and bracnhed. it contains one nucleus and is rectangular.
Cardiac muscle contraction is INVOLUNTARY. it is under the control of the autonomic nervous system.
muscle is found in the walls of the heart <3 !
,Qiz plant cell
Ans: only plant cells have cell walls, which help protect the cell and provide structural support. found
outside of the membrane.
Qiz Chloroplast
Ans: organelle found in cells of plants and some other organisms that captures the energy from sunlight
and converts it into chemical energy. aslo photosynthetic plays a role in photosynthesis
Qiz cell theory
Ans: discovered by theodor schwann. all living things are made of cells. cells are the smallest structural
units and basic building blocks of living things. cells contain everything necessary to keep living things
alive. varying in size and shape cells carry out specialized functions.
1. all living things are composed of one or more cells.
2. cells are alive and represent the basic unit of life
3. all cells are produced from pre-existing cells.
Qiz Autotroph
Ans: An organism that makes its own food.
they use basic raw materials in nature like the sun to make energy-rich biomolecules. plants are for
example they create chemical energy to grow through the process called photosynthesis which uses
carbon dioxide from the air and convert it into sugar molecules like glucose.
Qiz Heterotroph
,Ans: An organism that cannot make its own food.
Qiz cell cycle
Ans: series of events that cells go through as they grow and divide. cell cycle regulates cellular division
this process can either prevent a cell from dividing or trigger it to start dividing.
Qiz Interphase
Ans: Cells spends most of its time in this pahse. cells grows and copies its DNA
Qiz mitotic phase
Ans: stage of the cell cycle when a cell is actively dividing
order of stage cycle: G1,S,G2,M
Qiz G1 phase
Ans: the first gap phase during which the cell prepares to copy dna
Qiz S pahse
Ans: the synthesis pahse, DNA is being copied
Qiz G2 phase
, Ans: Second gap phase which the cell prepares for cell division
Qiz Correlations
Ans: observed associations between two variables
Qiz positive correlation
Ans: A correlation where as one variable increases, the other also increases.
Qiz negative correlation
Ans: as one variable increases, the other decreases. also known as an inverse correlation or an indirect
correlation
Qiz no correlation
Ans: no connection between the two variables
Qiz Gene
Ans: deoxyribonucleic acid A segment of DNA on a chromosome that codes for a specific trait
Qiz Chromosomes
