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.

Answer:
11. b.
Explanation:
Photosynthesis stores energy in carbohydrates, cellular respiration releases energy from carbohydrates.
Glucose, C₆H₁₂O₆, is a carbohydrate.
Write out the equations:
<u>Photosynthesis</u>
carbon dioxide + water + light energy => oxygen + glucose/sugar
CO₂ + H₂O + light => O₂ + C₆H₁₂O₆
The carbohydrate is stored in the plant until it needs it, like to perform cellular respiration.
<u>Cellular Respiration</u>
oxygen + glucose/sugar => carbon dioxide + water + ATP energy
O₂ + C₆H₁₂O₆ => CO₂ + H₂O + ATP
The carbohydrate is used to make energy. Energy is released from carbohydrates.
Glucose, C₆H₁₂O₆, is a carbohydrate.
Fault in other options:
a. Photosynthesis and cellular respiration both occur in plants. Plants have mitochondria for cellular respiration.
c. Photosynthesis uses carbon dioxide and cellular respiration releases carbon dioxide.
d. Photosynthesis uses carbon dioxide, cellular respiration uses oxygen.
Answer:
species richness,
Explanation:
species richness_______ is the number of different species represented in an ecological community, landscape or region. _species richness, ______ is simply a count of species, and it does not take into account the abundances of the species or their relative abundance distributions.
Explanation:
Biological hazards include microorganisms such as bacteria, viruses, yeasts, molds and parasites. Some of these are pathogens or may produce toxins. A pathogenic microorganism causes disease and can vary in the degree of severity
