Answer:
D. all options are correct
Explanation:
- There is a trade-off between the size of gametes and the number of gametes.
- The larger the gamete, the less mobile it is
- The probability that a zygote survives increases with its size, and the size of the zygote is a function of the sizes of the fusing gametes
Answer:
Explanation:
A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction. The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone.[1] These collisions happen on scales of millions to tens of millions of years and can lead to volcanism, earthquakes, orogenesis, destruction of lithosphere, and deformation. Convergent boundaries occur between oceanic-oceanic lithosphere, oceanic-continental lithosphere, and continental-continental lithosphere. The geologic features related to convergent boundaries vary depending on crust types.
Plate tectonics is driven by convection cells in the mantle. Convection cells are the result of heat generated by radioactive decay of elements in the mantle escaping to the surface and the return of cool materials from the surface to the mantle.[2] These convection cells bring hot mantle material to the surface along spreading centers creating new crust. As this new crust is pushed away from the spreading center by the formation of newer crust, it cools, thins, and becomes denser. Subduction begins when this dense crust converges with less dense crust. The force of gravity helps drive the subducting slab into the mantle.[3] As the relatively cool subducting slab sinks deeper into the mantle, it is heated, causing hydrous minerals to break down. This releases water into the hotter asthenosphere, which leads to partial melting of asthenosphere and volcanism. Both dehydration and partial melting occurs along the 1,000 °C (1,830 °F) isotherm, generally at depths of 65 to 130 km (40 to 81 mi).[4][5]
Some lithospheric plates consist of both continental and oceanic lithosphere. In some instances, initial convergence with another plate will destroy oceanic lithosphere, leading to convergence of two continental plates. Neither continental plate will subduct. It is likely that the plate may break along the boundary of continental and oceanic crust. Seismic tomography reveals pieces of lithosphere that have broken off during convergence

Height and weight are quantitative increase in the size of a certain anatomical structure.
<h3>What is Weight?</h3>
The gravitational force acting on the object, expressed as weight as a vector quantity. Some people refer to weight as a scalar quantity that measures the gravitational force's strength. Others define it as the strength of the force applied to a body by systems that work to counteract the effects of gravity. For example, a spring scale measures weight. As a result, the weight would be zero during free fall.
Terrestrial objects are capable of having no weight in this sense. For example, if we disregard air resistance, the famous apple falling from the tree and hitting the ground near Isaac Newton would have no weight.
