European starlings are agricultural pests. They damage crops and berries. European starlings also aggressively compete with native birds for the insects they eat. ... Large numbers of European starlings can cause dangerous and expensive damage to jet engines when they get sucked in.

The growing population of starlings has caused displacement of Eastern Bluebird from their normal nesting sites. This is an example of interspecific competition.

what is interspecific competition?

Two models Lotka-Volterra model of competition and the Tillman’s model of competition are used to describe the influence of exploitative competition among species.

Interspecific competition is defined as in an ecosystem when different types of species compete among themselves for the fixed and same resources like food, shelter, light, water, and the other essential necessities.

In such one organism may lower its population size because of not able to avail the limited resources where as other organism increase in the population and they also tend to limit the growth of that particular species.

Thus, competition occurs  in two ways either at an individual organism level, namely exploitative competition and interference competition.

Kingdom Animalia is one of the seven kingdoms living organisms are classified into. The Kingdom contains organisms called ANIMALS. They are eukaryotic i.e. possess a membrane-bound nucleus. Animals are heterotrophic i.e. they rely on other organisms for their source of energy (food).

In order to break down this food via metabolism, animals need oxygen to do so. This process is called respiration, and it yields energy in form of ATP, which is used by their cells to carry out cellular functions.

The independent variable is the fertilizer

The dependent variable should be the rate of growth of the plants

The constant doesn't change so other factors that affect plant growth and health, such as soil quality and watering, would need to remain constant.

The controlled variables might be things such as the the quality of soil and the amount of water given to the plants. If these factors were not constant, and certain plants received more water or better soil than others

The experiment in question 1 is a controlled experiment

The part of the garden that didn't receive fertilizer is the control group

According to the question; She didn't hypothesize .

In question 2 '

The independent variable is the floor wax

The dependent variable was protecting the floor tiles against scratches.

It is a controlled experiment but there's no much information to determine if there is any variability and repetition )

According to the concept of entropy, what will likely happen to most molecules over time? A.They will bind to other molecules. B.They will break down. C.They will remain unchanged. D.They will turn into carbon molecules.

Answers

Answer:

B.They will break down.

Explanation:

Entropy is defined as the thermal energy per unit temperature that contribute to doing useful work in a system. The concept of entropy says that entropy is measured by the random or disordered motion of molecules of a system.

As the entropy will increase over time, the molecules will break down into two or more due to the random and disordered motion of molecules.

Hence, the correct answer is "B.They will break down.".

It is also the atomic mass number of the atom.A neutral atom has an equal number of positive (proton) and negative (electron) charges.
