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.
Indicator species may provide useful substitute for large scale surveys to monitor biodiversity. Weconducted surveys in the Afro-alpine habitats of the Bale Mountains National Park (BMNP) with theobjective of identifying indicators for the species richness of the raptor guild. Raptors were countedby scan sampling technique from a suitable vintage point. Three classes of 18 sample units groupedaccording to the variability of the moorland ecosystem in the magnitude of process variables importantfor raptor species richness were used in determining the indicator value of species as a function of their abundance concentration and the percentage of species occurrence per sample group. Thisprocedure determined indicator values for all species in the resident raptor community. Comparisonwith randomly expected values demonstrated that only<span> Aquila verreauxii</span>and<span> A. chrysaetos</span>haveindicator values that were significantly larger than the randomly expected values. The species richnessestimated using the abundances of these two species predicted the observed species richness of thewhole community in a linear regression model that explained 66% of the deviance in the data set.Furthermore, the species richness of the community predicted by process variables had correlation of very high significance with that predicted by the indicator species. We have thus identified twoindicator species to a raptor guild of the BMNP and demonstrated that these two species encapsulatedmost of the information regarding the species richness response of the guild to key process variablesin the Afro-alpine moorland ecosystem. Our findings contribute significantly to current and futureefforts of monitoring the biodiversity of the park providing a cheap and quick means of data generation<span>relevant for making management decisions. Hope this helped! :)</span>
Well... Since 2+1=3 and 3+1=4 that means 3+4=7. Following me here? Good. Let's move on. Now, we take the 7 and multiply it by 4.4 to get 30.8. Now take your 30.8 and divide it by 360 (degrees; that is the circumference of a circle and the Earth is a circle) to get .08555 repeating. Now add them all up, it should look something like this... 2kg+1m+4.4m/s+.08555= ~8.25kgmm/s. Congratulations! You found the answer! It is about 8.25 kgmm/s squared. Good job!
I think the correct answer would be C. It would be restricting water and/or nutrients, instead of supplying ample quantities of both that would not change the results of the experiment. This is because you are still supplying the same amount of nutrients and other things needed by the plant so the ratio of the growth of the plants will still be the same.
Answer:
The most appropriate answer would be D. The western skink population would be separated into two groups, and genetic diversity would decline in each group.
It can be explained with the help of a bottleneck effect due to which population size decreases suddenly due to events like a natural disaster, habitat destruction et cetera.
The construction of the multi-lane highway would have destroyed the natural habitat of western skinks and separate them into two populations.
The separation of a population along with the destruction of habitat would result in a severe decrease in the population size of western skinks.
Consequently, the genetic diversity would also decrease.
