This dispersal reduces the likelihood that a sperm will find an egg. Many sperm and eggs die before achieving fertilization. The low success rate of external fertilization puts animals at a reproductive disadvantage compared to internal fertilization.

Which two details are most important to include in a summary of the excerpt?

excerpt from Robinson Crusoe

by Daniel Defoe

When I waked it was broad day, the weather clear, and the storm abated, so that the sea did not rage and swell as before. But that which

surprised me most was, that the ship was lifted off in the night from the sand where she lay by the swelling of the tide, and was driven up

almost as far as the rock which I at first mentioned, where I had been so bruised by the wave dashing me against it. This being within

about a mile from the shore where I was, and the ship seeming to stand upright still, I wished myself on board, that at least I might save

some necessary things for my use.

When I came down from my apartment in the tree, I looked about me again, and the first thing I found was the boat, which lay, as the wind

and the sea had tossed her up, upon the land, about two miles on my right hand. I walked as far as I could upon the shore to have got to

her, but found a neck or inlet of water between me and the boat which was about half a mile broad; so I came back for the present, being

more intent upon getting at the ship, where I hoped to find something for my present subsistence.

What is the number of neutrons in a helium atom?​
Goryan [66]

The number of neutrons in a helium atom is TWO (2).

  • Helium (He) is the second chemical element in the periodic table.

  • Helium consists of two (2) protons and two (2) neutrons in its atomic nucleus.

  • In consequence, the atomic number of helium is equal to two (2).

  • The Sun contains approximately 25% He, which is generated by solar fusion.

In conclusion, the number of neutrons in a helium atom is TWO (2).

Rapid lateral flow assays based on the quantification of magnetic nanoparticle labels for multiplexed immunodetection of small m
PolarNik [594]

A rapid lateral flow immunoassay is presented that uses carboxyl-modified superparamagnetic nanoparticles as labels that can be quantified by highly sensitive multi-channel electronic readers. The approach is generic in that it is likely to be applicable to numerous small molecules. The method permits both single- and multiplex assays at a point-of-need without sample pretreatment. It is user-friendly and offers attractive characteristics demonstrated here for detection of morphine, fentanyl and methamphetamine in . The competitive immunoassay uses commercially available reagents that do not require special permissions. After migration of sample, the lateral flow test strips are subjected to an alternating magnetic field at two frequencies. The response from the nanolabels is readout at a combinatorial frequency from the entire volume of a porous immunochromatographic membrane by the magnetic particle quantification technique.

application to the determination of drugs of abuse.

Estimating the detection time of a drug in urine is complex because of many different influencing factors and the lack of experimental data. Detection times vary depending on dose and route of administration, metabolism and characteristics of the screening and confirmation assays. Using a cut-off value of 1000 ng/mL, urinary samples can be positive for amphetamine for up to 5 days after intake of the drug.
