O The bird population would stay the same
O The bird population would decrease
O The bird population would infinitely increase

Answers

Answer 1
The bird population would most likely decrease as they have lost their main source of food but could also maybe stay the same as they can find a new food source

6. Learning that has taken place but is dormant until a situation requires it  - latent learning

How, explain your answer?

Activational effects are the sudden or immediate temporary transient effects of behavioural changes due to the influence of hormones, especially the gonadal or these hormones. The behaviour change in male animals due to an increase in male se hormonal activity can be referred as an activational effect.

Classical conditioning facilitates learning of a behaviour when a conditioned stimulus is associated with an unconditioned stimulus leading to a conditioned response. Animal training by pairing a new unconditioned stimulus with an already known conditioned stimulus, a new conditioned response of behaviour change can be observed.

Ethology refers to the scientific zoological study (includes both laboratories as well as natural field studies) of animals' behavior with relation to their natural environment. It studies and compares about animal behavioral processes changes under various disciplines like ecology, anatomy, evolution etc.

Habituation is an associative learning process that results when an animal learns to resist a stimulus and not to respond to it after repeated exposure.  

Insightful learning occurs when various parts of a problem are analyzed and their relationship is understood to arrive at the solution suddenly. Animals must look at a situation as a whole, and observe and analyze it to solve the problem. Some animals like chimpanzees can learn through insightful learning

Latent learning occurs without any associated reinforcements. Animals learn new behaviour through latent learning.

What element is missing from the cellulose molecule which is needed to make collagen?

Answers

I’m not sure if this is exactly what ur asking, but vitamin c, zinc, and copper are needed

The missing element that is needed to make collagen in cellulose is  vitamin C, zinc, copper and manganese to make the triple helix.

What is collagen?

Glycine, proline, and hydroxyproline are the three amino acids that make up collagen.

Cellulose synthesis is gaining popularity not only because cellulose is a major component of plant cell walls, but also because it has the potential to become a major resource for renewable biofuels.

The cellulose structure is made up of long polymer chains of glucose units connected by a beta acetal linkage.

The image on the left depicts a very small section of a cellulose chain. The monomer units are all beta-D-glucose.

Amino acids are the building blocks of proteins. These amino acids form protein fibrils with a triple helix structure.

To form the triple helix, your body also requires adequate amounts of vitamin C, zinc, copper, and manganese.

Thus, the missing elements are vitamin C, zinc, copper and manganese.

What types of weather events are not yet clearly linked to climate change?

Answers

Droughts that are more frequent and severe, storms, heat waves, rising sea levels, melting glaciers, and warming oceans can all hurt animals, ruin their habitats, and disrupt people's livelihoods and societies.

What is climate change?

Long-term increases in the earth's average surface temperature, as well as large-scale changes in global, regional, and local weather patterns, are caused by a considerable increase in the levels of greenhouse gases created by the burning of fossil fuels.

Dangerous weather events are growing more common and severe as climate change progresses.

Glacier melting occurs as a result of heat changes, particularly at relatively high temperatures. This is a process in which ice transforms from solid to liquid or water. Scientists have recently detected an alarming rate of glacier melting.

Unusually hot days and multi-day heat waves are a natural component of the weather's day-to-day fluctuations. Hotter-than-usual days and nights are becoming more prevalent as the Earth's temperature warms (see the High and Low Temperatures indicator), and heat waves are anticipated to grow more often and intense.

314 J to 250 J, what happens to the gravitational potential energy of the system?

A. It decreases from 316 J to 314 J.

B. It increases from 2 J to 66 J.

C. It decreases from 66 J to 2 J.

D. It increases from 316 J to 564 J.

Answers

Taking into account the definition of kinetic, potencial and mechanical energy, the correct answer is option B: the gravitational potential energy of the system increases from 2 J to 66 J.

Kinetic energy

Kinetic energy is a form of energy. It is defined as the energy associated with bodies that are in motion and this energy depends on the mass and speed of the body.

Kinetic energy is defined as the amount of work necessary to accelerate a body of a given mass and at rest, until it reaches a given speed. Once this point is reached, the amount of accumulated kinetic energy will remain the same unless there is a change in speed or the body returns to its state of rest by applying a force.

Potential energy

On the other hand, potential energy is the energy that measures the ability of a system to perform work based on its position. In other words, this is the energy that a body has at a certain height above the ground.

Gravitational potential energy is the energy associated with the gravitational force. This will depend on the relative height of an object to some reference point, the mass, and the force of gravity.

Mechanical energy

Finally, mechanical energy is that which a body or a system obtains as a result of the speed of its movement or its specific position, and which is capable of producing mechanical work. Then:

Potential energy + kinetic energy = total mechanical energy

The principle of conservation of mechanical energy indicates that the mechanical energy of a body remains constant when all the forces acting on it are conservative (a force is conservative when the work it does on a body depends only on the initial and final points and not the path taken to get from one to the other.)

Therefore, if the potential energy decreases, the kinetic energy will increase. In the same way, if the kinetics decreases, the potential energy will increase.

Gravitational potential energy of the system in this case

The principle of conservation of mechanical energy can be applied in this case.

A model train running on an inclined track is part of a closed system that has 316 J of mechanical energy.

The kinetic energy of the train is 314 J at the beginning.

Replacing in the definition of mechanical energy:

Potential energy + 314 J = 316 J

and solving you get:

Potential energy = 316 J - 314 J

Potential energy= 2 J

Then, the potential energy of the train is 2 J at the beginning.

The kinetic energy of the train is 250 J at the end.

Replacing in the definition of mechanical energy:

Potential energy + 250 J = 316 J

and solving you get:

Potential energy = 316 J - 250 J

Potential energy= 66 J

Then, the potential energy of the train is 66 J at the end.

Finally, the correct answer is option B: the gravitational potential energy of the system increases from 2 J to 66 J.

HELP ! ILL MARK BRAINLIEST !!!

Answers

Answer:

destruction of natural habitats

Explanation:

First let's define our main terms or each answer choice.

1)Decreased deforestation - Deforestation is the action of clearing mass amounts of trees for human use such as farms, buildings, houses etc. So this answer is basically saying that as the human population increased the amount of trees that get destroyed will decrease.

2)Destruction of natural habitats - Natural habitats is simply the natural home of animals. So this answer is saying as the human population increases the more number of animals natural homes will be destroyed

3)Unchanged climate - Climate is basically the long term weather of an area. So this answer choice is saying that as the human population increases the climate will remain unchanged.

4)Increased biodiversity - Biodiversity is the different kind of life on earth usually regarding a specific habitat or ecosystem. So this answer choice is essentially saying that as the human population increases the types of life on earth increases.

What comes with increased human population?

As the human population increases the need for food, houses, water, jobs etc increases as well. Keep that in mind while looking at the answer choices.

Determining the answer

Why the answer isn't A

Rereading 1) and then what comes with increased human population we can most definitely rule out A. As human population increases the need for houses and jobs increases. In order to have a good enough supply of wood and land for these houses and buildings for these jobs, deforestation must occur. So as human population increases deforestation would increase as well.

Why the answer is B.

Rereading 2) and then looking at what comes with increased human population we can maybe say that B is correct. Looking back at the previous section we've already identified that mass deforestation must occur to satisfy the needs for wood and land for houses and jobs for the increased population. As we know many animals probably live in these forests and inside of the trees so many of these animals homes would be destroyed resulting in the destruction of natural habitats ( animals homes )

Why the answer isn't C

After rereading section 3) and what comes with increased human population we can rule out C. If an increase in human population results in deforestation the amount of CO2 released into the air increases as well. If you didn't know trees absorb CO2 which is bad for the atmosphere. Once destroyed the trees release the CO2 that they have absorbed. CO2 and other green house gases create holes in our atmosphere leading to a change in climate as the suns radiation travels through these little holes. This results in a change in temperature, increased natural disasters and the melting of ice on the poles which also leads to increased temperatures. Deforestation isn't the only cause of this ( gasoline from cars, burning of fossil fuels , pesticides and many other human caused actions result in this ). These are all human caused things so if the human population increases the amount of green house gase emissions would likely increase as well meaning the climate would no remain unchanged.

Why the answer isn't D

After reading section 4) as well as the section titled "why the answer is B" we can rule out D. In order for an increase in biodiversity to occur, natural habitats must be preserved ( remain untouched ) if deforestation occurs then natural habitats will be destroyed and biodiversity will never increase as many animals may not be able to find another sustainable habitat. Not only that but the question asks about a negative affect and biodiversity is a good thing.
