<h2>Answer:</h2>
<u>Typical rates of sea-floor spreading are approximately </u><u>5 cm per year</u>
<h2>Explanation:</h2>
Sea-floor spreading is a process that happens at the mid-oceanic ridge where a divergent boundary is causing two plates moving away from one another resulting in spreading of the sea floor. To calculate the spreading rate of one side of a mid-ocean ridge by dividing distance by time (Distance/Time = Rate) The typical rates of sea -floor spreading are approximately is 5 centimeter per year.
The property of carbon that allows it to make very large organic molecules would be the ability of carbon to form a maximum of 4 covalent bonds. Due to its 4 valence or outermost electrons.
Answer:
Yes.
Explanation:
Yes, a new research indicates that dogs might use a magnetic sense to navigate. Dogs has world class nose which helps them to navigate to their destination but it also has a magnetic compass that helps them in navigation. The dogs use magnetic field of the earth to find out shortcut ways in the unknown land or terrain so the hypothesis is right that dogs used magnetic sense for navigation.
Answer:
Relationship between Yucca plant and Yucca moth is OBLIGATE MUTUALISM.
Explanation:
Obligate mutualism- The mutual relationship between two partners where both partners are benefited by each other and can not survive without each other.
In case of Yucca plant and Yucca moth,they cannot survive without each other.Yucca moth larvae feed on seeds of Yucca plant and Yucca plant have a single pollinator i;e, Yucca moth. Yucca moth collects pollen from anther and fly to another flower and transfer that pollen to other flowers stigma. In this way they transfer the pollen , usually they make a hole in the ovary to lay eggs and directly transfer pollen to the inside of the stigma.
After laying eggs they mark it with some special kind of pheromone which alerts other moths not to lay egg inside the same flower or lay some eggs not much. So that they can be protected inside the flower and can be developed well.
Answer:
Darwin's greatest contribution to science is that he completed the Copernican Revolution by drawing out for biology the notion of nature as a system of matter in motion governed by natural laws. With Darwin's discovery of natural selection, the origin and adaptations of organisms were brought into the realm of science
