Answer:
<h2>Every living thing has adapted to fit with where it lives. That’s what it takes for life to survive. Aquatic organisms live in water and have adaptations to do so. Fish guts. Fish are ectothermic. This means their body temperature changes as the surrounding water temperature changes</h2>
Explanation:
does it make sense ?
Answer:
Complete immersion in water is not essential for life for the yabby. If its gills are kept moist (humid air is sufficient), it can absorb oxygen from the air and survive for many days out of water. To breed, however, it must be in water.
The yabby has evolved an ingenious mechanism for surviving drought. As the ground dries up it burrows down following the falling water table, and seals the burrow entrance with an earthen plug. In a small, moist chamber at the bottom, the yabby enters a state resembling suspended animation, its bodily functions (respiration, pulse and digestion) practically ceasing. This mechanism is called aestivation (not hibernation, which is a winter adaptation of warm-blooded animals). The yabby can remain like this for years on end. Burrows well over 5 metres deep have been found.
The yabby is rarely found in clear water. Its natural habitat is usually muddy water, which (although probably not essential to life) may give some protection from predators. Some predators, such as fish, do not depend upon sight alone but can sense pressure changes, tracking their prey even in muddy water; cormorants too can find their prey in muddy waters.
Substrate type is not critically important, although the yabby is commonly found on muddy or silted bottoms with the occasional rock or fallen branch (in contrast to the leaf-littered, rocky or pebbly streams of the spiny crayfishes). Experiments have shown that growth is faster on a natural substrate such as mud or stones, than on an artificial one such as plastic tanks.

Hope that my answer helped. If my answer did help you then would you be kind to give me brainliest because I've been trying to rank up. If not then it's totally fine. Thanks :)
Answer:
If you think of the earthworm body plan as a drinking straw within a pipe "lining the straw" is the most of the tissues that developed from endoderm.
Explanation:
The physique of the earthworm is segmented which appears like numerous tiny rings combined or merged collectively. The earthworm is made of around 100-150 segments. The segmented body portions deliver significant organizational purposes. Segmentation can help the earthworm move. Each segment or piece has muscles and bristles named setae. The bristles or setae support anchor and governs the worm when stirring over soil. The bristles grasp a segment of the worm definitely into the ground while the other portion of the physique projects forward. The earthworm usages parts to either contract or relax self-sufficiently to source the body to grow in one area or contract in other areas. Division supports the worm to be supple and sturdy in its drive. If each section stimulated collectively deprived of being self-governing, the earthworm would be stationary.
Wind Pollination
Many of our forest trees are wind pollinated, as are important prairie plants such as grasses, ragweed, and sage. Some pollen eventually falls into lakes or peatlands where it collects with other sediments, layer after layer, year after year.
