I can’t see the picture well
The correct answers are: They provide localized regions of function and They are highly discrete and organized
Nuclear domains or bodies are membraneless structures within the nucleus that make nucleus compartmentalized. The function of these “compartments” is to enhance the efficiency nuclear processes. Nuclear bodies include:
• the nucleolus-the place where ribosome biogenesis occurs.
• Cajal bodies- consist of proteins and RNA; its functions are associated with telomerase assembly; in cells that divide rapidly
• splicing speckles –contain RNA splicing factors
• promyelocytic leukemia protein nuclear bodies-involved in programmed cell death; control cell division.
Blood typing is a method to tell what type of blood you have. Blood typing is done so you can safely donate your blood or receive a blood transfusion. It is also done to see if you have a substance called Rh factor on the surface of your red blood cells.
Answer: Some arid-climate plants are able to conserve water because of their reduced leaf size. Less leaf surface area results in reduced water loss through the epidermis. Small leaves have fewer stomata than larger leaves, and that adaptation also reduces water loss.
The main difference between species and genus is the taxonomic rankings that are used for biological classifications of organisms. Genus belongs to a ranking lower than family and above species, whereas species are organisms with similar characteristics that come below the Genus classification ranking.
