The average distance between the Earth and the Moon is 384 400 km.<br> Express it in standard form.
ycow [4]

Answer:

3.84\times10^8\ m

Step-by-step explanation:

It is given that,

The average distance between the Earth and the Moon is 384 400 km.

We need to express in in standard form.

1 km = 1000 m

It means,

384400 km = 384400000 km

or

= 3.84\times10^8\ m

Hence, the average distance between the Earth and the Moon is 3.84\times10^8\ m.

Estimate the isoelectric point of a ser–his dipeptide. explain why this value is only an estimate.
uranmaximum [27]
A dipeptide bond connects two amino acids. Ser stands for Serine while His stands for Histidine. Isoelectric point is when all charges of the two amino acids cancel out. This can be estimated by finding the average of the isoelectric points (pI) of the two amino acids.

Serine: pI = 5.68
Histidine: pI = 7.59

Average pI = (5.68 + 7.59)/2 =<em> 6.635

</em>
<em />This is only a rough estimate because an arithmetic average will not coincide with the biochemistry of the amino acids. The true value of the isolectric point is determined through experimentation. However, it would be more ore less around 6.635.<em>
