A. Cytoplasm is manufactured
B. The Cell splits in two
C. DNA separates into two nulclei
D. Chromosomes are duplicated

Answers

Answer 1
S phase is the DNA synthesis phase. During this portion of the cell cycle, the cell replicates its entire complement of DNA. It also forms the centrosome, which is the microtubule-organizing center that will eventually help the cell pull apart the DNA that will be divided between daughter cells.

similarities between chromosphere and corona

Answers

Explanation:

Beginning from the outside, they are: the corona - the outermost, hot shell of the atmosphere. the chromosphere - a transparent layer between the corona and the photosphere. the photosphere - the visible "surface" of the Sun.

Explanation:

The chromosphere is above the photosphere, the visible "surface" of the Sun. It lies below the solar corona, the Sun's upper atmosphere, which extends many thousands of kilometers above the chromosphere into space. The plasma (electrically charged gas) in the chromosphere has a very low density

1. Short-term hormonal influences on animal behaviour usually occurring late in life  - activational effects

2. A technique that associates a natural response to a stimulus to an unrelated stimulus; also called Pavlovian conditioning  -- classical conditioning

3. The study of animal behaviour in its natural environment  - ethology

4. When an animal learns not to respond to a stimulus  - habituation

5. Finding a solution to a once unsolvable problem  - insightful learning

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.

Thus, this could be the answer.

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

what would most likely happen if a person increased the amount of saturated fat in his or hers diet?

Answers

Answer: If a person increased the amount of saturated fat in his or her diet there is a chance of risk of cardiovascular disease would increase.

Explanation: Increase in the amount of saturated fat in diet results in the increase of levels of cholesterol in blood. This cholesterol is in the form of LDL.

If a person increased the amount of saturated fat in his or her diet, then the person would be more likely to suffer from heart and blood vessel-related disease and obesity as well.

What is the harmful effect of saturated fatty acids?

Because saturated fatty acids are completely saturated with hydrogen, they require more energy to break down and generally remain in the solid at room temperature, as well as inside the body, where they can induce heart-related diseases and obesity by blocking blood vessels. For example, butter contains saturated fatty acids, which are generally not recommended in large quantities.

Hence, if a person increased the amount of saturated fat in his or her diet, then the person would be more likely to suffer from heart and blood vessel-related disease and obesity as well..

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.
