Loni makes a diagram to help organize what she has learned about the gas laws.
Which label belongs in the region marked X?
involves changes in temperature
has a constant volume
shows an inversely proportional relationship
does not describe pressure changes
Answer:
Shows an inversely proportional relationship.
Explanation:
The Boyle's law belongs in the region marked X whereas the other circle belongs to Charles law. There is inverse relationship between the two circles or these two laws because in Boyle's law, temperature is constant while on the other hand, in Charles law pressure is constant instead of temperature. In Boyle's law, pressure of a gas is inversely with its volume whereas in Charles law, the volume of a gas is directly proportional to its absolute (Kelvin) temperature.

Base your answers the questions below on the information provided and your knowledge of biology. Ocean-dwelling (marine) iguanas and land iguanas inhabit the Galapagos Islands. Some scientists believe that both types of iguanas diverged from a common ancestor. Marine iguanas eat algae. Land iguanas feed on cacti. Algae are more abundant in the ocean than cacti are on the islands. Both species lay their eggs in the sand. Rats, cats, and goats have been introduced to the islands by humans. Rats feed on iguana eggs, cats eat baby iguanas, and goats eat cacti. • Which population of iguanas, marine or land, would you expect to be larger? Support your answer. • Identify one technique that can be used to support the conclusion that these two species of iguana developed from a common ancestor.
Answer:
- The marine population is likely larger because the food supply is greater for the marine population than that of the land iguanas
- Evolution (natural selection), adaptive radiation
Explanation:
Evolutionary adaptation can be defined as the process of adjustment of organisms to particular environmental conditions in order to increase their chances of survival. Moreover, natural selection is the main mechanism by which organisms adapt to their environments. Adaptive radiation can be defined as the evolution of a specific taxonomic group (for example, a species o genus) into specialized organisms which are adapted to survive under particular environmental conditions. Adaptive radiation can lead to speciation by which populations evolve (change) to become distinct species.

The chemical substances in our environment to which we respond can be called?
A. stimuli
B.impulses
C.responses
D.sense cells
A. Stimuli
WHAT IS STIMULI?
A stimuli is anything that can trigger a physical or behavioral change.The changes in the environment to which living things respond are called stimuli. The living things show response to external stimuli such as heat, light , touch, sound, smell, taste, water and chemicals.It can be internal or external both.When diverse organs works collectively in a scientific way to supply a reaction to the stimulus, this is known as coordination.Stimuli is essentially anything that triggers a receptor for one of those senses.You can understand this with an example that would be the receptors on our skin which sense a stimulus like pain. Sense organs contain groups of receptors that respond to specific stimuli.

A backyard pond has 5 kol (goldfish), rocks, lily pads, water, algae, and a water pump.
Which parts of this ecosystem would be the non-living parts:
Which parts would you consider to be a population?
Which parts would you consider to be a community?
Answer:
Non-living/abiotic parts of this ecosystem would be the water, rocks, and water pump.
The 5 Koi fish would be considered a population as they are a group of individuals of the same species living within an area.
The fish, the lily pads, and the algae would be considered a community. All of these organisms are interacting with each other to make the community healthy.

The behavioral genetics approach __________. examines the direct influence of genes by studying behavior at the cellular leveL cannot explain how genes and environment influences behavior is a strict behavioral approach to studying the influence of the environment on the expression of physical traits in related individuals relies on the evaluation of dreams and the unconcious desires
Answer:
relies on the evaluation of dreams and the unconscious desires.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
A trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her. Some examples of traits in genetics are colorblindness, handedness, curly hair, height, complexion, weight, hair color, dimples, tongue-roll, etc.
This ultimately implies that, the manner in which living organism such as humans look and behave is largely dependent on both the traits inherited from their parents and the environment in which they grew up or stayed.
Hence, the behavioral genetics approach relies on the evaluation of dreams, unconscious desires, twin, family, and adoption studies which are used to investigate the gene possessed by living organisms or their environment interactions.

At transform fault boundaries plates moving in opposite directions have a tendency to get stuck resulting in the build-up of large amount of what?
Answer:
The correct answer is - energy.
Explanation:
Transform fault boundaries are the plates that move one past another without causing damage or destruction to the crust, these form when two plates move in the opposite direction or in the same direction.
At transform fault boundaries plates moving in opposite directions have a tendency to get stuck which leads to a high amount of energy formation. There is no damage or destruction that takes place nothing occurs but earthquakes along with the fault.

Why is it important for geologists to use both relative and absolute ages to determine the age of rocks?
Answer:
to help and determine the exact age of the rocks
Explanation:
The study of rocks strata is known as stratigraphy. It is useful and helps the scientist and the researcher to study the earth's crust and its past.
Scientist could age the rock using two methods. They are :
Relative ages
Absolute ages
Early scientist could determine the exact age of the rock of the earth's crust. They use to find the relative ages of the layers of the rocks and then determine how one rock layer is older or younger than the other. But with advancement and development of carbon dating, scientist could tell the exact age of the rocks found on the earth's crust.
The Scientists uses the relative as well as the absolute dating technique to date the rock layers. They organize the rock layers based on their age and scale from the oldest to the youngest on a geologic time scale. So an exact date of the rocks can be determine by using the two methods of relative age and the absolute age.
The products of photosynthesis (glucose and oxygen) are used in cellular respiration. The products of cellular respiration (water, and carbon dioxide ) are used in photosynthesis.
A. True
B. False
Answer:
A. True
Explanation:
The processes of photosynthesis and cellular respiration are extremely correlated because they are part of the same cycle. They are both in the carbon cycle. This works because they each produce what the other needs. It is a constant back and forth reusing the same atoms and cycling all of the molecules. This allows the world to never run out of carbon or other important elements.
