Organisms adapt to their changing environment. When there is some pressure in the environment (for example, increased competition for food), then species with the most advantageous adaptations will survive. Because environments change pretty frequently, the organisms living there must cope with this change. This leads to ever changing and evolving species and increased biodiversity. Lastly, a high level of biodiversity leads to a healthy ecosystem because of the vast variety of organisms in that space. Many species allows niches to overlap and therefore no one organism occupies one niche.
Answer:
Pelvic body cavity
Explanation:
There are four basic body cavities
The dorsal, thoracic, abdominal and the pelvic body cavity. For the question, the sperm can find itself inside the pelvic body cavity, the pelvic body cavity encapsulates the reproductive organs and the bladder. The reproductive organs then includes the vagina, uterus, and fallopian tubes (oviducts) etc. Thus, the sperm can pass through organs of the reproductive system in the pelvic body cavity.
Answer:
True.
Explanation:
Yes, the lens of the eye will be more spherical when the ciliary muscles are contracted due to tension. When the relaxation occurs in the ciliary muscle , the zonular tension is increased, that causes the lens to be flatten and leads to decrease in optical power while on the other hand, when the ciliary muscle contracts, the tension in the equatorial zonular is increased which causes the central lens surface to become more rounded that leads to increases central optical power.
