Asked in Botany or Plant Biology, Daffodils
Can daffodils be fertilised from a crocus?
A crocus has the following classification Sub-division: Angiosperm Class: Monocot Order: Asparagales (Liliales) Family: Iridaceae Subfamily: Crocoideae Genus: Crocus A daffodil has the following classification Sub-division: Angiosperm Class: Monocot Order: Asparagales (Liliales) Family: Amaryllidaceae Subfamily: Amaryllidoideae Genus: Narcissus As you can see, the crocus and daffodil are in different families. That means that their DNA will not be similar enough to pair up correctly, so even though you can put pollen on a daffodil and vice versa, you can make viable seeds from a daffodil/crocus cross....
Asked in Chemistry
What account for solid matter to be definite in shape while liquid and gas to be indefinite in shape?
because of its molecules solid molecules are very close to each other that's why they make definite shape, while liquid and gas molecules are far apart. ...

What is the parts of matter?
Atoms make up matter. Inside of atoms are electrons (negitive charge), protons (positive charge), and nuetrons (no charge). If you mean the States of Matter . . . There are 3 main States of Matter. Solid, Liquid, & Gas. Solid: Particles are packed closely together, and solids have a definite shape and a definite volume. Liquid: Particles are loosely packed, have no definite shape but a definite volume. Gas: Particles are spread out, and have no definite shape and no definite volume. There is a...

Asked in Chemistry
What happens to make dry ice smoke?
Dry ice is I believe carbon in solid form. At room temperature it immediately turns from solid to gas bypassing the liquid stage of matter. It is simply to warm for it to keep its solid form at room temperature. Its solid temperature is close to -200 degrees fahrenheit. ...
Why a gas has not definite shape and not definite volume?
The reason why a gas does not have a definite volume and a definite shape is because the atoms and molecules spread out when the amount of space between them increases. It is like when you blow a balloon, you need to blow hot air to increase the energy for the atoms and molecules to spread much farther apart from each other to make the balloon bigger. All of this has to make the balloon float in the air. It makes perfect...
