Answers

The volume of phosphoric acid is mathematically given as

X= 75 mL of H3PO4

What is the volume of H2PO4  required?

Question Parameters:

Milliliters of 0.750 M H2PO4 are required to react with 250. mL of 0.150 M Ba(OH)2

Generally, the equation for the  banlanced Chemical Reaction is mathematically given as

2 H3PO4 + 3 Ba(OH)2 ------> Ba3(PO4)2 + 6H2O

Therefore

The volume of phosphoric acid=[tex]\frac{3*2*250*150*3*1}{1*2*750}[/tex]

The volume of phosphoric acid=0.075 L of H3PO4

In conclusion, the volume of H2PO4  in mL is

The volume of phosphoric acid=75 mL of H3PO4

If a enzyme denatures, it slows down because:

• It begins to use a new substrate

• it gets bigger and can’t move

• it changes shape and the substrate won’t fit

• it become to small

Answers

Answer:

The answer would be "C" because when an enzyme denatures, it changes it shape so that the substrate won't fit anymore. On a side note, when an enzyme is placed in an environment out of its pH or tempertaure range, it can denature.

What role do surface properties play in determining the lifespan of a flu virus?

Answers

Answer:

Surface properties have less to do with virus lifespan than does the type of virus. Viruses tend to remain viable for longer on non-porous materials than on porous ones. Viruses tend to remain viable longer on surfaces with low moisture content.

Explanation:

The surface properties in the lifespan of a flu virus are associated with the fact that viruses tend to remain viable for longer on non-porous materials than on porous ones.

Influenza (flu) viruses are contagious viral infections capable of affecting the airways of the lungs.

It has been shown that flu viruses survive on human tissues for only 15 min because of their surface properties.

Moreover, it has been shown that these viruses cannot survive on non-porous metal/plastic surfaces by more than 9 hours.

In conclusion, the surface properties in the lifespan of a flu virus are associated with the fact that viruses tend to remain viable for longer on non-porous materials than on porous ones.

Before Mendel's work, many hypotheses were proposed to try to explain heredity. The best known of them is that there were small animals inside the man, which were called animalcules. In man, this miniature became known as a homunculus.

What was genetics like before Mendel?

The first ideas about heredity were quite simple and only claimed that children were similar to parents, without understanding the mechanism behind this finding. Genetics is the part of Biology that studies heredity, that is, the way in which characteristics are passed on from generation to generation.
