Answer:

First law of thermodynamics is the conservation of energy states that energy is not created and not destroyed but only can be stored.

Thermodynamics second law states that total entropy of a system increases from lower to higher system and some of the energy is always wasted during the work done.

In the food chain plants are the producers which accept light energy and stored in the form of chemical energy and energy flow to the herbivores and higher trophic levels in the chemical form only and no new energy is created in between the chain (Fisrt law of thermodynamics). Heat is generated during respiration by plants and animals (wasted energy) and entropy also increases with the increase in level of the pyramid of energy (Second law of thermodynamics).

On the graph below, what would explain why the rabbit population levels drastically increased instead of decreasing drastically?

Ilia_Sergeevich [38]

Based on factors affecting population, the rapid increase in the rabbit population could be dues to high fertility rate, abundance of food and lack of predators.

<h3>What is population increase?</h3>

Population increase refers to the increase in the number if species of an organism found in a given habitat over time.

Increase in population can be brought about by factors such as;

abundance of food
high fertility rate
favorable environmental conditions
lack of predators

Therefore, the rapid increase in the rabbit population could be dues to high fertility rate, abundance of food and lack of predators.

In humans, the quadriceps muscle is a skeletal leg muscle under voluntary control. As such, it contracts in response to signals

Masja [62]

Answer:

The correct answer is - operation of reflex arc.

Explanation:

The reflex arc is a unique and special type of neural pathway that starts with a sensory neuron and ends with a motor neuron. In this operation sensory neuron acts as the receptor and motor neuron is effector. This type of neural circuit helps in faster response.

Voluntary muscles like quadriceps muscle are normally in control voluntarily however, such muscle may contract involuntary due to reflex arc. This type of contraction takes place before the signal has even reached the brain.

In this response the sensory neuron takes the signal to the spinal cord and then motor neuron to the effector muscle for faster response.

Thus, the correct answer is - operation of reflex arc.

Many kangaroo rats live in the Sonoran desert of the southwestern United States. They have a variety of adaptations for living i

SVETLANKA909090 [29]

Adaptations. The kangaroo rat is almost perfectly adapted to life in the desert. They can survive without ever drinking any water, getting needed moisture from their seed diet. They have excellent hearing and can even detect the silent sound of an owl approaching.

Hope this helps!
