What else can I help you with?
What is a structure made mostly of DNA molecules?
A chromosome is a structure made mostly of DNA molecules. Chromosomes are found in the nucleus of cells and contain genes that carry hereditary information.
Humans are what -based life forms?
Humans are carbon-based life forms. Carbon is a key element found in all living organisms and plays a crucial role in the molecules that make up our cells and tissues.
Would iron be the trace element present in hemoglobin molecules in the red blood cells?
Yes.
Are cells composed of primarily inorganic molecules?
Cells are not composed primarily of inorganic molecules. This is because cells are found in living things which are made up of organic matter.
Do living organisms consist mostly of of hydrogen based compounds?
Yes, living organisms consist mostly of hydrogen-based compounds such as water (H2O) and organic molecules like carbohydrates, proteins, lipids, and nucleic acids. Hydrogen is one of the most abundant elements in biological systems and plays a crucial role in maintaining the structure and function of living cells.
How many types of atoms and molecules are found in cells?
Atoms are the same. In fact mostly light but molecules are very very large. So large that you cant write most of their symbol on the page
What element accounts for most of the dry weight of cells?
Carbon is the element that accounts for the most dry weight of cells, typically making up around 50% of a cell's composition. This is because carbon is a key component of organic molecules like proteins, lipids, carbohydrates, and nucleic acids that are essential for the structure and function of cells.
How do some molecules get into cells?
Some molecules get into cells by going through their permeable membrane.
Do plants have carbon in their structure?
Yes, plants have carbon in their structure. Carbon is a key element in the molecules that make up plant cells, such as carbohydrates, proteins, and fats.
Level of organisation in a plant does molecules come before cells?
Yes. Cells are made of molecules.
Is cell larger than molecule?
Cells are larger than molecules. Cells normally have molecules inside them and constantly passing through their membranes. Cells normally contain water molecules along with glucose and other molecules.
The cytoplasm of cells is made mostly of what?
The cytoplasm of cells is mostly made up of water, along with various salts, ions, and organic molecules such as proteins, carbohydrates, and lipids. It also contains cellular organelles, such as mitochondria, ribosomes, and the endoplasmic reticulum.
