Answer:
Infectious diseases are caused by pathogens, which include bacteria, fungi, protozoa, worms, viruses, and even infectious proteins called prions. Pathogens of all classes must have mechanisms for entering their host and for evading immediate destruction by the host immune system. Most bacteria are not pathogenic.
Explanation:
Answer:
Increase EDV and therefore, increase stroke volume.
Explanation:
EDV is the volume of blood which filled the ventricle before its contraction while ESV is the volume of blood remain in ventricle after ejection.
When venous return increases, this will increase the pressure on ventricle contraction which can lead to eject of addition blood returned to it.
So, increase in EDV results in an increase of stroke volume (SV).
Answer:
(-) sense single-stranded RNA
Explanation:
Negative sense refers to viruses that use the negative sense single stranded RNA as their genetic material.
It is essential for the negative viral strand is complimentary to the mRNA so it is converted to a positive RNA by RNA polymerase.
Negative sense single stranded RNA virus require an RNA dependent RNA polymerase for transcription. This is because it essential in encoding proteins by catalyzing the complimentary RNA strand to the given RNA tempelate.
Answer:
because, it resembles the properties of alkali earth metals as well as halogens ! OwO
Explanation:
" Hydrogen resembles the properties of alkali earth metals as well as halogens. Hydrogen has one electron in its valence shell and it also needs one more electron to get stable. ... For this the hydrogen is placed separately in periodic table ! "
