Fibrinogen comprises 7% of blood proteins; conversion of fibrinogen to insoluble fibrin is essential for blood clotting. Plasma proteins, such as albumin and globulin, that help maintain the colloidal osmotic pressure at about 25 mmHg. Electrolytes like sodium, potassium, bicarbonate, chloride, and calcium help maintain blood pH. Immunoglobulins help fight infection and various other small amounts of enzymes, hormones, and vitamins.

There are 450 calories in 100 g of trail mix. If you burn 30 calories in 10 minutes of walking, how much trail mix should you eat to replenish the energy you spend walking for 2 hours?

Answers

Answer:

to replenish the energy spent walking for 2 hours, 80g of trail mix should be eaten

Explanation:

Firstly, let us calculate the number of calories burnt in 2 hours

in 10 minutes; 30 calories are burnt

∴ in 1 minute 30/10  calories are burnt = 3 calories are burnt

2 hours = 120 minute

∴ in 120 minutes 3 × 120 = 360 calories are burnt.

Next, let us calculate the amount of trail mix that contains 360 calories

100g of trail mix = 450 calories

450 calories = 100 g

1 calory = 100/450

∴ 360 calories = 360 × (100/450)

=  360 × 0.222 = 80g

∴ to replenish the energy spent walking for 2 hours, 80g of trail mix should be eaten

The following passage explains the relationship between tectonic plates and earthquakes. Which sentence states incorrect information?


Tectonic plates can push together, pull apart, or slide past each other at their boundaries. The edges of tectonic plates are not smooth, so they create friction as they move. When friction is too great for the plates to move, they can become stuck and pressure can build up. An earthquake occurs when pressure that has built up between plates suddenly is released. The buildup of pressure that leads to earthquakes only occurs at plate boundaries.​

earthquakes occur when the edges suddenly become unstuck and slip along a fault

What conditions are necessary for rocks to melt?

Answers

Answer:

In explanation.

Explanation:

The rock is pulled down by movements in the earth's crust and gets hotter and hotter as it goes deeper. It takes temperatures between 600 and 1,300 degrees Celsius (1,100 and 2,400 degrees Fahrenheit) to melt a rock, turning it into a substance called magma (molten rock).

The rock can be melted when high pressure and high temperature are applied to it, and due to the compression relaxation, the rock melts. The different types of rocks need different temperatures.

What is the effect of temperature on different substances?

Temperature plays an important roles in different substances, such as high and low temperatures, each with its own set of tasks. The high temperature can melt the solid substance into a liquid, and further heating converts the liquid into gas. Because of the high pressure and temperature in the earth's core, the rock is in a molten state, but when it comes out of the earth's core, after solidifying, it converts into solid rock. The low temperature converts the liquid into a solid, and food preservation is carried out by this process.  

Hence, the rock can be melted when high pressure and high temperature are applied to it, and due to the compression relaxation, the rock melts.
