Answer:
because humans, just like monkeys are mammals and part of the primate family
No, humans are the only organisms that experience boredom.
Yes, boredom is a likely explanation for the spider monkeys’ behavior.
No, emotions of non-human organisms cannot be tested.
Yes, the hypothesis could be tested through a controlled experiment.
Answer;
-Crossing over and random independent assortment.
The two events that increase the genetic diversity of the daughter cells produced are crossing over and random independent assortment.
Explanation;
-During prophase of meiosis I, the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments, which resulting to recombination that creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.
-Additionally, when cells divide during meiosis, homologous chromosomes are randomly distributed during anaphase I, separating and segregating independently of each other, this results in gametes having unique combinations of chromosomes.
Not all minerals are considered gemstones because the designation of a gemstone depends on a combination of factors, including its beauty, rarity, durability, and demand in the market. Here are some reasons why not all minerals are classified as gemstones:
Beauty: Gemstones are valued for their aesthetic qualities, including color, clarity, brilliance, and luster. Not all minerals possess these desirable visual characteristics. Some minerals may be dull, opaque, or have unappealing colors that do not meet the standards of what is considered attractive for a gemstone.
Rarity: Gemstones are often associated with rarity, which increases their desirability and value. While many minerals exist abundantly in nature, only a few occur in gem-quality quantities. The scarcity of certain minerals contributes to their classification as gemstones, as they are prized for their relative scarcity compared to more common minerals.
Durability: Gemstones are expected to be durable and withstand the rigors of everyday wear and handling. Not all minerals possess the necessary hardness, toughness, or resistance to scratching and chipping required to be considered suitable for use in jewelry or other decorative purposes. For example, talc, the softest mineral, is not suitable as a gemstone due to its low hardness.
Market Demand: The perception of value and demand for a mineral as a gemstone is influenced by cultural, historical, and fashion trends. The desirability of certain gemstones can change over time, driven by factors such as fashion trends, marketing, and cultural preferences. While a mineral may have the necessary qualities to be classified as a gemstone, if it lacks demand in the market, it may not be widely recognized or used as a gemstone.
It's important to note that gemstones are a subset of minerals, and the distinction between gemstones and other minerals is often subjective and based on human preferences. Some minerals may be considered gemstones in certain contexts or cultures while not being widely recognized as such globally.

The coelacanth is another lobe-finned fish that is a living fossil. It is thought to have evolved into roughly its current form about 408 million years ago, during the early Devonian, and has not essentially evolved further from its ancient form.
A fossil index is a paleontological or archaeological remain whose presence can be used to date with some precision the stratigraphic unit in which it is found because they are particular or exclusive of a certain period of geological history, or of Prehistory, or indicators of a certain paleoenvironment.
In general, the taxa or cultural modes of the past that gave rise to the guide fossils had a very short duration on a geological -or historical- scale, which means that their presence is limited to chronological -or cultural- coordinates, in the case of prehistoric cultures-, very limited. That is, if a guide fossil appears in a stratum, that stratum can be dated with enough accuracy.
Therefore, The coelacanth is another lobe-finned fish that is a living fossil. It is thought to have evolved into roughly its current form about 408 million years ago, during the early Devonian, and has not essentially evolved further from its ancient form.
