Answer:
e) a drive
Explanation:
We felt thirsty when we have fluid imbalance in our body either we have less water or we have more concentration of osmolytes such as sodium in blood. The brain detect the change produce the effect for the intake of water.
- However thirst is a vital primordial emotion that motivates us for fluid intake. So the emotion produces a drive to quench it.
- Some recent studies refers it as basic instinct to drink water.
Animals such as bees or wind can carry pollen from one flower to another flower and fertilize the plant that way. Plants can also self-pollinate which happens when a plant’s own pollen fertilizes its own ovules.
Answer: By definition, if the atomic number =
7
, then there are 7 protons, 7 electrons, and 8 neutrons!
Explanation:
The atomic number is by definition the number of protons, positively charged particles, contained within the atomic nucleus. So if there are 7 protons, there MUST be 7 electrons, 7 negatively charged particles. Why? Because matter is electrically neutral, and positive and negative particles must be equal.
Electrons have negligible mass; the mass number depends on the number of protons contained within the nucleus, PLUS the number of neutrons. Given that we have 15 N
, there must be 8 neutrons contained within the nucleus. does this help?
Answer:
Paleontology in the real world isn't as careless and usually in movies they mis-label things. Paleontology isn't as simple as it seems and in many movies they portray little effort or processing and handling of the fossils. It requires much attention and you have to take care of the bones. Jurassic Park is a great example of fake paleontology and comparing it to real paleontology can surprise you.
Explanation:
<span>Characteristics that mentioned biomes have in common are:
- They are all forests, dominated by trees and other woody vegetation.
- They inhabit animal life with great microbial diversity.
- They all have big carbon sinks.
Still, trees different in a number of ways in these three biomes:
- </span><span>Tropical rainforest: Trees are evergreen and have large green leaves. Canopy is multilayered and dense, so there is a little light in the forests.
- </span><span>Temperate deciduous forest: Trees are deciduous, leaves are lost annually. Canopy is moderately dense, so there is more light than in tropical rainforests.
- </span><span>Boreal forest: Trees are evergreen conifers with needle-like leaves. Canopy is thick and permits low light penetration.</span>
