The answers would be 24 and fertilises. 

Pollen is the male gamete of lily, which is a haploid cell, with only half the chromosomes of the normal diploid ones. Therefore, if the haploid gamete has 12 chromosomes, so the diploid would be 12+12 which makes 24. 

The egg is also a gamete of lily, but it's a female gamete. It is also a haploid cell, with only 12 chromosomes which is given in the question. So, when the sperm fuses and fertilises the egg, the zygote would have 24 chromosomes which is formed by 2 haploid gametes.

It would be 24 chromosomes. Diploid just means 2 so, you just multiply 12•2=24 (your diploid number). It is produced when the pollen containing sperm, fertilizes the egg.

One group of students did an experiment to study the movement of ocean water. The steps of the experiment are listed below.
Delvig [45]

Answer:

Explanation:

The lamp and the ice bag were at the same place.  

Sounds like the experiment was intended to show on a small scale ocean currents from the poles to the equator and back to the poles. The bag of ice would simulate the cold at the poles while the lamp would simulate the heat provided by the sun near the equator. With that in mind, let's look at the possible flaws and see what is likely.  

Not enough ink was added.

 * If you can see the ink, then there's enough ink. So this isn't the correct choice.  

Not enough water was taken.

 * Possibility there wasn't enough volume of water to setup a current, but not too likely since the baking dish was filled. So let's look further. 

 The dish was too small for the experiment.

 * Same as above. It might be this, but there's something more likely. 

 The lamp and the ice bag were at the same place.

 * This sounds like a winner. In the real world, the poles are cold and the equator gets more sunlight. So there's a temperature gradient. In the described setup, both the heat sink (the bag of ice) and the heat source (the lamp) were at the same location.

Hydrogenated vegetable oils are typically ________ than vegetable oils that have not been hydrogenated.
Phantasy [73]
To hydrogenate means to add hydrogen. When adding hydrogen, you saturate the fat (removing the double bonds). Saturated fat has a higher melting temperature, is more stable and more unhealthy. 

Unsaturated fat has a lower melting temperature, is more healthy but more unstable.

2. Explain what the term "blood shift" means and how it works.
katrin [286]

Answer:

Explanation:

Left shift or blood shift is an increase in the number of immature cell types among the blood cells in a sample of blood.

For all of the above, you can say that blood shift (BS) happens (blood moves from non-vital organs to vital organs) when PV happens, but quite common Freedivers are using the term BS when describing the movement of the blood to the chest cavity to protect it from increasing pressure while diving deep.
