You are describing the solar nebula theory to a friend. You point out that it provides an explanation for the regular motion in

our solar system, the division of the planets into terrestrial and Jovian types, and an explanation for the origin and nature of comets and asteroids. Your friend agrees that this is all very nice, but that it seems that the solar nebula theory fails the basic criteria for a scientific theory, to make predictions about the natural world that can be observationally tested. In her opinion, all the solar nebula theory does is explain known facts, albeit in a compelling and economical way. How would you answer your friend and make the case that the solar nebula theory is indeed a scientific theory that has passed many observational tests? What are some predictions that the solar nebula theory has made that were confirmed only within the last decade or so?

Explanation:

The widely accepted theory which explains the formation of the solar system is known as the Nebular theory of origin.

The Nebular theory states that the solar system is formed by the explosion of the large gaseous clouds in the centre due to various factors which took place around 457 million years ago.

The explosion leads to the formation of the dust particles which accumulated in large amount in the centre and the suspended particles revolved around it and formed the planets and the centre is known as the sun.

The theory can be proved as :

1. the direction of rotation of planetary bodies are in the same around the same direction.

2. The suspended particles formed the disk around the planets.

3. The planets near the Sun are small and possess lass amount of metals and the silicates whereas the planets far away from the Sun-like Jupiter are larger due to the presence of these metals and silicate which attracted the hydrogen and Helium.

When mammals get an infection, their internal body temperature often rises 2 to 3 degrees Celsius. The body gets the energy it n
Paladinen [302]

Answer:

The correct answer is increasing the rate of cellular respiration in mitochondria.

Explanation:

In mammals like humans, the infection causes a rise or hike in the body temperature of an individual up to 2 - 3 degrees Celsius. Infection results in thermoregulation strategies control by the hypothalamus, of the host by immune system transmitted integration signals, hormonal and neuron lead and increase in metabolic reactions by the increase the rate of the cellular respiration takes place in the mitochondria and that elevate body temperature. Mitochondria releases energy in the form of ATP that helps in body temperature as it is an exothermic reaction.

The correct answer is increasing the rate of cellular respiration in mitochondria.

adell [148]

Answer:

B) cAMP

Explanation:

Phosphodiesterase is an enzyme that breaks a phosphodiester bond, for example in molecules such as cAMP and cGMP. So, phosphodiestarases are  are regulators of signal transduction: regulate the duration of signaling pathway.

Caffeine is  central-nervous-system stimulant and the mechanisms of its action usually are: mobilization of intracellular calcium or inhibition of specific phosphodiesterases.

Define the five systems. Be sure to include enough information to distinguish each system from the others. (Site 1)
VladimirAG [237]
By definition, a body system is primarily comprised of different organs and tissues that work one another to achieve a common body process. These body systems would include:

Circulatory system - concerns with the circulation of blood
Digestive system - breaking down of food particles 
Skeletal system - composed of bone structures serving as our body's framework
Nervous system - composed of nerve cells that responds to different stimuli
Respiratory system - concerns of utilising the entry of oxygen and the exhalation of carbon dioxide.

The model below shows the structure of a portion of a plasma membrane in an animal cell. The model shows the structure of a port
Romashka-Z-Leto [24]

Answer:

The amphipathic property of the phospholipids that constitute the membrane

Explanation:

It seems like a options-based answer so it would be better if they were included here but basically, each of those phospholipid molecules has two parts with antagonistic reactions towards water.

The head is polar or hydrophilic, wich means it can be sorrounded by water. The tail, is apolar or hydrophobic which means it is repelled by water.

The interior and exterior of the cell is contain water-based substances, that's why the heads of the phospholipids are oriented like that with the tails protected inside the membrane.

This double layer structure has a fundamental role in the fluid property of the cell membrane from which derive most of it's functions.
