It is false that u<span>nlike third-world and developing nations, the u.s. has no incidence of hungry or malnourished people.
You can find hungry people anywhere - even in the richest countries in the world. Not everyone has the same opportunities and living conditions, so it is only normal that there will be poor people who cannot afford even food.</span>
density and specific gravity are properties used to help identify minerals. Density is a measure of the mass of a certain volume of the sample. Specific gravity is a unit less measure, and it is the ratio of the mass of a substance to the mass of an equal volume of water. density and specific gravity are properties used to help identify minerals.

Spindle fibers extend from the poles and overlap at the spindle equator where some attach to chromosomes to help separate them during cell division.
<h3>What is spindle fiber?</h3>
A single filament that travels from the poles to the center is a spindle fiber. Aster is a single filament as well, but the aster differs in its placement.
<h3>What is spindle equator?</h3>
Chromosome alignment at the spindle equator improves the efficiency of bi-orientation. Chromosome congression, a procedure that moves chromosomes from close to spindle poles to the equator, is necessary for this alignment to take place.
<h3>What is spindle in cell?</h3>
A protein structure called a spindle fiber divides a cell's genetic material.

<span>Ecological balance can be defined as the equilibrium or stability of species
(animals and plants) to natural conditions or environment. A decrease in the
variety or diversity of, environment or those natural conditions which may
result in an imbalance or instability of the ecological balance means a
reduction in biodiversity.</span>
Darwin’s ideas operate on the basis that organisms must change to survive in their environment. One of the key aspects of these changes is that they help the organisms utilize resources as effectively as possible. If there were unlimited resources there would not be a need for change. Malthus’s studies in limited resources shows how human populations changed to best use the resources available.
