Predict how the sympathetic reflexes controlling blood vessels would respond to a sudden decrease in blood pressure
Goryan [66]
<span>Baroreceptors are special receptors that detect changes in your blood pressure. Important baroreceptors are found in the aorta and the carotid sinus. If the blood pressure within the aorta or carotid sinus increases, the walls of the arteries stretch and stimulate increased activity within the baroreceptors.</span>

Which of the following is directly involved in driving protein import into the mitochondrial matrix space? A. GTP hydrolysis out
kumpel [21]

Answer:

The correct answer is D; ATP hydrolysis inside mitochondria

Explanation:

Proteins imports brought into the matrix of mitochondria are normally taken up from the cytosol in practically less time after their discharge from ribosomes. Transportation of protein imports into the matrix is driven by energy which is supplied by:

  • <u>ATP hydrolysis outside the mitochondra: </u>this occurs in the first step of translocation process. ATP hydrolysis drives the release of newly synthesized polypeptides from the hsp70 group of chaperone proteins.
  • <u>an electrochemical proton gradient</u> across the inner mitochondrial membrane maintained by electron transport process in the inner membrane.
  • <u>ATP hydrolysis in the matrix</u>: Hsp70 chaperone proteins in the matrix space likewise have a job in the translocation procedure, and they are the third point in the import procedure at which ATP is expended.

Indicate weather the label identifies an adaptive or innate form of defense
suter [353]

Innate: keratinized epithelium

stratified squamous epithelium hypodermal areolar connective tissue antigen presenting cells major histocompatibility complexes complement (antibody -dependent pathway )

Innate or non-specific response is the first defense against invaders. Components of this response include physical (e.g. skin . mucosa) and chemical barriers against pathogens and cells such as Natural Killer cells, macrophages, neutrophils, dendritic cells, mast cells, basophils, eosinophils. Innate response reacts immediately.

Adaptive: immunoglobulin plasma cells agglutinin

helper t cells memory t cells cytotoxic t cells cd4+cells

t lymphocytes

Adaptive immune response or specific response is specific to the pathogen presented and mediated by lymphocytes, B and T cells. Adaptive immune response creates immunological memory after the first, initial l response to a specific pathogen which leads to enhanced response.

Which of the following organelles is involved in the modification and routing of molecules to the exterior of the cell or to var
DerKrebs [107]

Answer:

The correct answer is e. Golgi apparatus

Explanation:

Golgi apparatus are also known as Golgi bodies and it bound by only a single membrane. It is present near the endoplasmic reticulum in the cell. Golgi apparatus is composed of 5-8 membrane-bound sac-like structures called cisternae.  

The Golgi apparatus plays important role in the modification of molecules like proteins and lipids. The unprocessed proteins that are released from the endoplasmic reticulum enter the Golgi apparatus and in the Golgi apparatus its modification like glycosylation and phosphorylation occurs.

Then these processed proteins are released outside from the Golgi in vesicle forms which have a signal molecule that guides it to various locations in the cell or towards the plasma membrane from where it can move out of the cell.

Therefore the correct answer is e. Golgi apparatus.

Both euglena and Cyanobacteria are photosynthetic unicellular organisms found in pond water. The feature that distinguishes eugl
Fed [463]

The correct answer is option C, that is, the presence of the nuclear membrane.  

Cyanobacteria is a phylum of bacteria that attain their energy via the process of photosynthesis, and are the only photosynthetic prokaryotes possessing the tendency to generate oxygen. As a prokaryote, they are devoid of the nuclear membrane.  

Euglena refers to a single cell flagellate eukaryote. It comes under the class Euglenoidea. The species of Euglena are witnessed in salt water and in freshwater. Being a eukaryote, they possess nuclear membrane.
