Answer:
More oxygen is needed to produce more energy, and more carbon dioxide waste must be removed from the body.
Explanation:
Answer: Different cells have different jobs to do. Each cell has a size and shape that is suited to its job. Cells that do the same job combine together to form body tissue, such as muscle, skin, or bone tissue. Groups of different types of cells make up the organs in your body, such as your heart, liver, or lungs.Differentiation means that one cell performs a different function than another cell, depending on where it is in your body. ... All the cells contain the same genetic material and all of them are from one original cell that started as a fertilized egg, but they look different and act different from one another. Under a microscope, fat cells look like bulbous little spheres. Like other cells in the body, each has a cell membrane and a nucleus, but their bulk is made up of droplets of stored triglycerides, each of which consists of three fatty-acid molecules attached to a single glycerol molecule. Skin cells are specialized to be quickly shed and replaced, and do not have much mitochondria (which helps produce energy). Muscle cells, conversely, have lots of mitochondria because they need energy to produce movement. Unlike many other cells, red blood cells have no nucleus and can easily change shape, helping them fit through the various blood vessels in your body. Unlike most other eukaryotic cells, mature red blood cells don't have nuclei. When they enter the bloodstream for the first time, they eject their nuclei and organelles, so they can carry more hemoglobin, and thus, more oxygen. Each red blood cell has a life span of around 100–120 days. Skin cells are specialized to be quickly shed and replaced, and do not have much mitochondria (which helps produce energy). Muscle cells, conversely, have lots of mitochondria because they need energy to produce movement. brainliest??
Explanation:
The cell grows and develop and the chromosomes duplicate. Also, interphase is the phase where the cell spends most of its time in.
Answer:
organelle- part of a cell (example- mitochondrion)
cell- basic unit of structure (example- muscle cell)
tissue- group of some cells (example-muscle tissue )
organ- one or more types of tissue (example- stomach)
organ system- group of organs working together (example- digestive system )
Organism- individual living thing (example- goat )
Explanation:
Organization of living things! Hope this helps.
Answer:
d. Tryptophan would bind to the repressor
Explanation:
However,the repressor would not be able to bind to the operator and switch off transcription.The cell would still be making tryptophan even though it is being supplied by the medium in which it is growing.This is a waste of energy.
