Answer:
Probably because a drought does not mean that water disappears.
Turning off the faucet doesn't mean that water can't go down the drain, right?
The right answr is hydrogen bonds
The hydrogen bond or hydrogen bridge is an intermolecular force involving a hydrogen atom and an electronegative atom such as oxygen, nitrogen and fluorine. The intensity of a hydrogen bond is intermediate between that of a covalent bond and that of van der Waals forces.
The helices of the DNA (both strands) are maintained by hydrogen bonds.
<h2>Inside the cones of pine tree</h2>
Explanation:
- The life cycle of a pine tree starts in the strobulus, the sexual conceptive structure in a completely adult pine tree. Strobulii is otherwise called the "pine cones." Male strobulii are in the lower some portion of the tree, while the female structures are in the upper part. The strobulli are viewed as unisexual structures since they have either male or female sexual organs. The male strobulli in a pine tree contains microsporocytes, grains that in the end form into dust. In the spring months, male strobulli discharge dust into the air, which is focused on the pine tree's female strobulli.
- A pine seed finds the right micro-climate, it will in the eventually sprout and a pine seedling begin to develop. Be that as it may, pine seeds are typically discharged in a torpid state, which is regularly broken by chilly stratification. Therefore, a pine seed won't grow until the accompanying spring when warm climate and some spring dampness are available. Since pine seeds are created in rich numbers, and just a small rate should be successful in building up new seedlings.
Answer:
The mass of a substance is constant according to the law of conservation of mass.
Explanation:
According to the law of conservation of mass, matter can never be created or destroyed in a chemical reaction, even though it may undergo change from one physical state to another.
This means that in an isolated or closed system, the mass of matter will always be the same irrespective of the type of change that matter undergoes. This is so because, the mass of a substance is a measure of the quantity of matter in that substance and is constant. The number of particles does not change during a change of state, only their spacing and arrangement. In solid ammonia, the particles are more compact and arranged, whereas in gaseous ammonia, they are more randomly spaced out.
Answer: Photosynthesis makes oxygen that plants can release into the atmosphere.
