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:
obesity increases blood pressure
Explanation:
This is because the high fat percentage in the body has lead to a build up of fat on the inside of arteries and this makes them thinner. the heart has to pump harder to get the blood around the body and through these, now smaller arteries. therefore yes having diabetes does increase blood pressure.
other factors which increase blood pressure are high stress levels, smoking, anxiety.
Answer:
They would be a damage of cells because homeostasis regulate the internal body environment so as to maintain a steady state to provide optimum conditions for normal and efficient functioning of the body cells.
