Answer: alpha
Explanation: Alpha particles are fast moving streams of positively charged particles that are shown to be Helium nuclei. They have a mass
number of 4 and an atomic number of 2 and a charge of +2. Alpha particles are represented as 4He2. When 238U92 becomes 234Th90, it emitted a helium nucleus 4He2. The equation for the decay is 238U92 ---> 234Th90 + 4He2.
D. A plant using sunlight to make good
The pond is considered as a the crayfish's
A) habitat
This is because the pond is where the crayfish lives and where it gets its food. It does not stray far from it and go back to it just to get food. It stays in the same location.<span />
Answer: Resource partitioning
Explanation:
In order to make organisms of different species (competitors) coexist, limited resources are to be divided with a ecological area.
Organisms of same species could be made to live together, so as to reduce wastage of limited resources
Capillary action<span> (sometimes </span>capillarity<span>, </span>capillary motion<span>, or </span>wicking<span>) is the ability of a </span>liquid<span> to flow in narrow spaces without the assistance of, or even in opposition to, external forces like </span>gravity<span>. The effect can be seen in the drawing up of liquids between the hairs of a paint-brush, in a thin tube, in porous materials such as paper and plaster, in some non-porous materials such as sand and liquefied </span>carbon fiber<span>, or in a cell. It occurs because of </span>intermolecular forces<span> between the liquid and surrounding solid surfaces. If the diameter of the tube is sufficiently small, then the combination of </span>surface tension<span> (which is caused by </span>cohesion<span> within the liquid) and </span>adhesive forces<span> between the liquid and container wall act to propel the liquid.</span><span>[1]</span>
