When the temperature of the outside air exceeds their internal body temperature, jackrabbits living in hot, arid lands will when

the temperature of the outside air exceeds their internal body temperature, jackrabbits living in hot, arid lands will dilate the blood vessels in their large ears to transfer more body heat to the environment. increase motor movements to find a sunny area to maximize heat transfer into their bodies. constrict the blood vessels in their large ears to reduce transfer of external heat to the blood in their ears. begin involuntary shivering of their skeletal muscles in order to generate more metabolic heat. increase pigmentation in their ears, darkening them to maximize their capacity to take up heat?

The answer is: 'constrict the blood vessels in their large ears to reduce transfer of external heat to the blood in their ears.' This is an example of thermoregulation. Thermoregulation is the ability of the<span> </span>body to keep body temperature<span> within certain boundaries, even when the temperature of the surrounding environment is very different. The regulation of temperature by thermoregulating organisms is one aspect of </span>homeostasis. By using heat exchange systems, such as employed in this example, the animal will need to expend less energy on behavioural adaptations to maintain a constant body temperature.

Insect hormones and their receptors ________. A. act independently of each other B. are a focus in pest control research C. util
Leokris [45]

Insect hormones and their receptors are a focus in pest control and research. Hence, Option B is correct.

Some of the insect hormones such as ecdysone (molting hormone), JH (juvenile hormone) and their analogs can be used for biological  control of pests.

Option A: Hormone receptors are proteins that bind hormones and form hormone receptor complex to maintain cellular activities.

So Option A is incorrect.

Option B: Some of the peptide hormones used in pest control and research. So Option B is correct.

Option C: Peptide hormones interact with only cell surface whereas aminoacid derivatives and thyroid hormones directly interact with nucleus. so Option C is incorrect.

option D is incorrect.

1.each of several hierarchical levels in an ecosystem, comprising organisms that share the same function in the food chain and the same nutritional relationship to the primary sources of energy.

A scavenger is an organism that mostly consumes decaying biomass, such as meat or rotting plant material. Many scavengers are a type of carnivore, which is an organism that eats meat. While most carnivores hunt and kill their prey, scavengers usually consume animals that have either died of natural causes or been killed by another carnivore.

Scavengers are a part of the food web, a description of which organisms eat which other organisms in the wild. Organisms in the food web are grouped into trophic, or nutritional, levels. There are three trophic levels. Autotrophs, organisms that produce their own food, are the first trophic level. These include plants and algae. Herbivores, or organisms that consume plants and other autotrophs, are the second trophic level. Scavengers, other carnivores, and omnivores, organisms that consume both plants and animals, are the third trophic level.

Nitrogen is converted from atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation. The majority of nitrogen is fixed by bacteria, most of which are symbiotic with plants. Recently fixed ammonia is then converted to biologically useful forms by specialized bacteria.

if a flower were orange would it more likely be pollinated by insects or by the wind give at least one reason for your answer
yan [13]

It would more likely to be pollinated by insects.


This is because the bright color of the petals can attract insects towards the flower thus sticking some pollen grains and transfer them to the stigma (female part of flower).


On the other hand, the color of petals do not really have effect on the wind pollination. Therefore this explains why wind pollinated flowers usually have small or dull colored petals.
