The question must refer to the modern classification system in biology.
It started with the work of Linnaeus - so its early version can be called a Linnaean classification - but right now it has been expanded and changed to fit the evolutionary relationships between the species - which is the best description, i.e. the answer is "it is based on the evolutionary relationship of the species"
Answer:
Although direct calorimetry is considered to be the most precise technique for the measurement of metabolic rate, construction of such a chamber that is large enough for doing exercise physiology research (or any research for that matter) is extremely expensive and not at all mobile.
Explanation:
Direct calorimetry measures the heat production of an individual, in calories, when placed in an insulated chamber where the heat is transferred to surrounding water. This is a very accurate method of measuring energy expenditure.
Answer:
A protein that is destined to be secreted from the cell:
- is targeted to the RER as a soluble protein.
Explanation:
The main function of the RER is the synthesis and transport of secretion or membrane proteins.
If you are looking for the RER you could fount it on eukaryotic cells, side by side of the nucleus, and cover in ribosomes.
The positioning of the body where are major body parts are flexed is called the fetal position. In this position the back is arched forward and arms and legs are drawn closer to the torso and the head bowed. It is called this because this is the position the fetus is in as it develops in the womb.
Answer:
Duplication of hox genes is important in the radiation of animals because they are regulating genes of symmetry and the body plan of the animals' bodies. Some change or mutation in these genes during duplication can cause mutations and with these evolution of the species as it controls the different segments of these animals as they develop, launching the genetic programs that form various body structures, such as limbs and organs. .
