Answer:

Luster

Explanation:

Luster is defined as the property of a mineral by which the light is reflected from the mineral's surface. It is a physical property and it differs from mineral to mineral. This property helps in the identification of minerals.

There are mainly two types of luster. They are as follows-

(a) <u>Metallic luster-</u> When a mineral has a shiny appearance, then it is called a metallic luster. For example, Pyrite.

(b) <u>Non-metallic luster-</u> When a mineral does not have any shiny appearance, then it is regarded as a non-metallic luster. For example, Quartz.

The non-metallic luster is again divided into several types, such as pearly, earthy, dull, silky, resinous and vitreous luster.

Answer:

the kidneys excrete salt into the urine when dietary salt levels rise

Explanation:

Hyponatremia is an electrolyte imbalance, with a low level of sodium in the blood. The normal value of sodium in adults is 136 to 145 mEq / L. Sodium is an element, or electrolyte of the blood. Sodium chloride is commonly known as table salt.

Certain conditions can cause decreased sodium in the blood. Specific causes of hyponatremia include:

Water poisoning (water replacement without electrolyte replacement).

Problems in the kidneys, heart or liver.

Medications: such as diuretics, Heparin, certain chemotherapeutics (Aminoglutethimide, Cyclophosphamide and Vincristine).

Conditions related to steroids, hormones or metabolic defects, such as a syndrome that alters the secretion of antidiuretic hormone (SSIHA). If this occurs, you urinate frequently and the kidneys excrete too much sodium. This can result from many conditions, including certain types of lung cancer.

Sam started his morning walk from the location indicated by the point below.
mel-nik [20]

Answer:

(-1,-3) on the coordinate grid.

Explanation:

The location from where Sam started his morning walk is 3 units to the left and 2 units up from the origin. This location is indicated by the point (-3,2).

He walked 5 units south and met his friend Joshua.

So, find the point that is 5 units to the south of point (-3,2). Distances north and south on the map represent a change in the y-coordinate. Moving 5 units to the south on the map from point (-3,2) places the new location at point (-3,-3).

Sam then walked 2 units east, where he met his friend, Ethan.

So, find the point that is 2 units to the east of point (-3,-3). Distances east and west on the map represent a change in the x-coordinate. Moving 2 units to the east on the map from point (-3,-3) places the new location at point (-1,-3).

So, Sam met Ethan at the location indicated by point (-1,-3) on the coordinate grid.
