Answer:
Explanation:
Proteins in the plasma membrane have several functions based on their components, location etc. For instance, if the protein transcends the entire plasma membrane it could be a transport protein, responsible for the import and export of certain molecules between the cell and the extracellular matrix (ECM). If the proteins are resting at the surface of the cell, facing the ECM, their role could be to detect components in the ECM, relaying a series of messages back to the nucleus so that the cell can ‘decide’ what it should do with this information (is it being told it should undergo apoptosis, should it begin to divide, should it migrate?). As well as this, it could be involved in the detection of foreign bodies such as pathogens. This is an extremely job for these proteins because if the cell does come in contact with a pathogen, the cell can use these proteins to engulf the pathogen and through a series of steps, present the antigen on their major histocompatibility complexes (either 1 or 2 depending on the cell type) or HLA’s for human cells. Thus it can be concluded that protein functions vary widely in the plasma membrane and due to the vast number of proteins that can be found there, it’s difficult to narrow down the exact main of functions of all these proteins put together.
Answer:
Answer is hypodermis .
Explanation:
The hypodermis which is also known as the subcutaneous tissue layer, is found lying beneath the dermis and act as a passageway or channel through which blood vessels and nerves passed. It is made up of fat and connective tissues.
It acts as an insulator, this, help in keeping the body temperature stable.
Answer:
The answer is A. Bacteria and Archaea
Explanation:
Answer:
More energy
Explanation:
More energy is needed to carry out the metabolic rate of a person ( the minimum amount of energy required to carry out all of the reactions needed to keep a person alive).
Answer:
Dorsal Cavity include the cranial cavity and spinal cord, meninges and cerebral canal also called the spine.
Ventral Cavity include lungs,,abdominalcavity,mediastinum,diaphragm.
Explanation:
The dorsal body cavity is located at the dorsal side of human body. It consist of spinal cord , cranial cavity and they are lined by meninges. The meninges serves as the covering and protective membrane for the dorsal cavities.
The ventral body cavity is found in the anterior part of the human body. It consist of thorasic cavity and abdominopelvic cavity. The abdominopelvic cavity consist of abdominal cavity which comprises of digestive organs and pelvic cavity which include the urinary bladder, reproductive organs. The thorasic cavity include the chest, lungs ,heartand mediastinum which divide the thorasic cavity
