Answer:
A.)are ectothermic organisms with variable body temperatures.
Explanation:
Invertebrates animal are animals that lack a backbone, Land invertebrates include insects,spiders, centipedes ,coelenterate, an arthropod, mollusc and the rest.
Ectotherms are also called called cold-blooded animal because their bl body temperature regulation is dependendent on external sources, such as sunlight or a heated rock surface. Some of the examples of ectotherms are fishes, amphibians, invertebratesand reptiles. The aquatic ectotherms body temperature is usually compare closely to the temperature of the surrounding water
Ectothermic species that lives in temperate regions usually experience rapid and potentially stressful changes in body temperature simply because of weather changes even among amphibians there is variation in their temperature
It is believed that naturally occurring periods of temperature variation negatively impact amphibian health.
During a 30 year period, the yearly frequency of drought is 10%, which is experienced in three separate years.
Additionally, drought is a period where precipitation is below average and thus resulting in prolonged shortages of water supply as far as both ground and surface water are concerned. This can last for several months or even for years.

Answer:</h2>
<h3>Interphase</h3>
<h2>
Explanation:</h2>
<h3>The cell cycle is the period of time from the beginning of one cell division to the beginning of the next. The longest stage of the cell cycle is called interphase. Interphase is the stage that occurs in between cell divisions. During interphase, the cell grows and develops and performs its functions.</h3>
Answer:
A) habitat fragmentation makes it easier for cowbird parasitism to occur
Explanation:
It is a situation where by there is transformation of a large habitat into smaller patches with smaller total area secluded from one another by a habitat different from the initial one.
Habitat fragmentation can be caused due geological processes which distort the physical environment. It is also casued by human activities which could lead to loss or extinction of certain species.
Habitat fragmentation could possibly lead to loss of habitat and biodiversity.
Answer:
The tail of the sperm helps the sperm move it gives the cell movement.
Explanation:
It moves and undulates so that the cell can travel and attach to the egg.
