Answer:
Temperature and pressure progressively increase with increased proximity to Earth's core. Recent studies indicate the core's temperature may be close to 11,000 degrees Fahrenheit; that's nearly 2,000 degrees warmer than previously thought and hotter than the surface of the Sun, according to a 2013 Forbes article.

Answer:
The correct answer is option D. "lipid".
Explanation:
Lipids, known also as fats or oils, are organic compounds that are insoluble in water and are made up of carbon, hydrogen, and oxygen. The formula of this question shows a biomolecule that is made up of this three atoms, and even though carbohydrate are made up of this three atoms as well, we can determine that it belongs to a lipid because it contains many more hydrogen atoms than oxygen atoms. Other characteristic of lipids is their long chains of carbon and hydrogen atoms, which are represented by the lines shown in blue. I attached the missing formula.
Explanation:
New ocean crust is formed at the mid ocean ridges. The new crust is then pushed away from the ridge as newer crust comes to the surface. The ocean crust then spreads out enlarging the ocean. The farer away from the ridge the ocean crust is the older the crust
Similar to the other types of muscle, smooth muscle contraction is caused by the sliding of myosin and actin filaments over each other. Calcium initiates contractions in a different way in a smooth muscle than in a skeletal muscle.
Smooth muscles use less energy to generate the given amount of force, can substain contractile force without fatigue & uses calcium from the sarcoplasic reticulum & extracellular space.
Answer:
C (Chlorophyll)
Explanation:
Adenosine triphosphate (ATP) is an energy carrying molecule in all living cells. It is the usable form of energy by cells. Organisms are able to carry out cellular functions using the energy carried by ATP molecules. ATP like other molecules is made up of components that make up its chemical structure.
ATP is composed of three structural components; A five-carbon sugar called RIBOSE at the core of its structure, attached to a nitrogenous base called Adenine and phosphate group (three in ATP). The energy in ATP is released when it loses its phosphate component.
Chlorophyll is a pigment found in the Chloroplast of plant cells. It is another molecule that is made up of its own components e.g nitrogen, magnesium etc.
