About how many red blood cells could fit across the diameter of a human hair? Cells A cell is the basic unit of life. The cells comprise different cell organelles such as cytoplasm, mitochondria, ribosomes among others. The organelles have distinct functions. This question is...
Bacteria are the only cell type classified as prokaryotic, lacking membrane-bound organelles. Most bacteria are single-celled organisms. Bacteria replicate through a process called binary fission (bi means two). Through binary fission, an asexual form of reproduction, one bacteria divides into two...
Ribosomes are found floating in the cell cytosol, cellular organelles such as mitochondria or the protoplasm of bacteria. Using electron microscopy, Eva Kummer and her colleagues Giang Nguyen and Christina Ritter have managed to produce a 3D model of a part of the human cell, the ribosome, whic...
To comprehend how we can gain access to such precise numbers, we have to ask ourselves: how does a breathalyzer work? What do those figures mean? And how do police officers find out if someone they suspect has been drinking is actually legally drunk? Many officers in the field rely ...
"There are many different kinds of behaviors, and each depends on different brain circuits. Key examples include: reflexes; innate and conditioned reaction patterns; instrumentally acquired habits; instrumental goal-directed actions based on trial-and-error learning; and instrumental goal-dir...
Molecules are made up of atoms that are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among atoms.
How we inherit characteristics. Parents pass on traits or characteristics, such as eye colour and blood type, to their children through theirgenes. Some health conditions and diseases can be passed on genetically too. Sometimes, one characteristic has many different forms. ...
The spatial regulation and licensing of NLRP3 rely on a highly dynamic network of intracellular organelles and interaction partners, facilitating the maturation of this protein into the active form. In addition, the temporal order of the described events remains elusive in many cases; along with the...
During mitosis, two daughter cells form, each of which has a. a lesser number of chromosomes than the original cell. b. a different number of chromosomes than the original cell. c. twice as many chromosomes as the original cell. d. half as many chromosom ...
A cell is described as the basic functional unit of life in all the living organisms. It is the smallest and biological unit and therefore, also known as the building blocks of life. It consists of various cell organelles that make a cell fully functional....
