Butterfly shape - Each fluorine is attached to the sulfur by a single covalent bond. The SF3 molecule is very short-lived and its structure has not been determined experimentally. It is calculated to adopt a butterfly-shaped molecular geometry, belonging to the Cs point group.
Answer:
The answer is : Carbon catabolite repression
Explanation:
Carbon catabolite repression is a vital part of the global control system of the bacteria and other microorganisms. It allows the microorganisms to quickly adapt to the preferred energy and carbon source first. This is generally achieved by the inhibiting the synthesis of the enzymes that are involved in the catabolism of other carbon sources.
This effect was first shown to be initiated by glucose. Therefore, the carbon catabolite repression is also known as glucose effect.
Answer: hair color and height.
Explanation:
I would select A because cells have to divide into smaller cells depending on where they are.
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.
