It is well known that women with poorly controlled PKU during a pregnancy put their baby at risk for developmental issues, poor head growth (microcephaly), poor overall growth, heart defects, and other structural birth defects.
Explanation:
A microscope is an instrument which makes an object appear bigger than it is. It took the invention of this relatively simple tool to lead to the discovery of cells<span>. In the 1660s, Robert Hooke began using microscopes to look at all sorts of materials. Anton van Leeuwenhoek took up similar work in the 1670s.</span>
Answer:
Cellular metabolism
Explanation:
A virus takes over the <u>cellular metabolism</u> of the host cell when it reproduces.
Answer:
A
Explanation:
Because there are two DNA strands in the DNA molecule and they both rotate around each other in a helix formation. So two helixes = double helix.
Explanation:
Sediment discharge was historically approximately 270 million cubic meters/year of suspended load and 130 million cubic meters/year of bedload. This has decreased 80% since 1850 and can be divided into three periods: historical period (pre 1900), pre-dam period (1932-1952), and post dam (1963-1982). Suspended sediment loads declined 43% between the historical and pre-dam and 51% from pre-dam to post-dam periods. The size of sediment also decreased drastically including a 72% decrease in the sand fraction. Most of this is due to dams on the tributaries acting as sediment traps primarily for the coarser sediments. Large-scale land clearing for agriculture contributed to increased sediment loads in the historic period.
