Answer: Nation A might be overusing their natural resources causing them to need it from Nation B. However Nation B knows this which might cause Nation A the trouble of getting that source.
1. To force laws in preventing the overuse of natural resources
2. Making recycling must be necessary and used.
3. Making electric cars and putting gas restrictions.
4. To create forests in certain areas making sure laws prevent people from cutting it down.
5. As well as preserving fresh water. Instead, use salt water and convert it to save that fresh water.
The proteins that helps in decreasing the activation energy of a reaction to occur at a definite temperature range and pH value in a living cell are called as the enzymes. These proteins are considered as the biocatalysts. All these biocatalysts are made up of proteins. All the enzymes are proteins but all proteins are not enzymes. Hence the answer is enzymes.
The answer is C. The Experiment!!!!!
Answer:
Answer is option A.
Orchid bees are to Brazil nut trees as breezes are to pine trees.
Explanation:
In Brazil nut trees, the female orchid bees act as pollinators that help in pollination. In pine trees, wind or breeze helps in pollination.
Pine trees are gymnosperms and so they do not have flowers to attract pollinators like bees or butterflies or birds. They are wind-pollinated. Pine trees are monoecious i.e., both male and female reproductive structures (pine cones) are present on the same tree.
The male cones (catkins) produce pollen grains that are lightweight, less sticky and have air bladders or small wing-like structures. As a result of these features, the pollen grains can be easily carried and dispersed by the breeze. In order to prevent self pollination (pollen falling on the female cones of the same tree), the male cones are normally located on the lower branches of the pine tree.
The female cones are located on the upper branches of the tree and the center of the cone contains eggs or ovules. The pollen grains that are carried by the wind, fall on the female cone of another pine tree. Each pollen grain grows a pollen tube into the center of the cone and the nucleus cell of the pollen travels through the tube and reaches the egg, where it combines with the egg to form an embryo. The embryo eventually grows into a seed. The seeds of pine trees are then dispersed by wind or animals such as squirrels.
