1 answer:

6 0

Animals ingest food containing carbon sources such as carbohydrates, proteins and lipids. (Which they get from plants that have absorbed and converted the carbon dioxide into other energies). They then metabolise these substances to produce waste products. One of these waste products is carbon dioxide which they breathe into the atmosphere. Also animals faeces is broken down by bacteria which give off carbon dioxide as they do so.

Which of the following best describes the term cleavage? a. Cleavage describes the quality and amount of light reflected from a

Debora [2.8K]

Answer:

Cleavage is the splitting of minerals along natural planes of weakness

Explanation:

There are different physical features of a mineral that are used in the identification of species of fossils. The characteristics may include hardness, Fracture, tenacity, and, cleavage. The cleavage, therefore, occurs as a result of the strengthening of the weaker bonds and the greater lattice spacing that exist in the plane. The lattice accompanies the more fragile relationship along with the place because the link cannot maintain interatomic spacing.

The property of cleavage and positioning of fracture derived from structural species of the crystals.

the average of two number is 55 to subtract from the greater number ratio between number become 1:2 the smaller number is

Thepotemich [5.8K]

Complete question:

The average of two number is 55. If 2 is subtracted from the greater number, the ratio between the numbers become 1:2 . The smaller number is

Answer:

The smaller number is 36

Explanation:

let the smaller number = x

let the greater number = y

$\frac{x + y}{2} = 55\\\\$

x + y = 110

y = 110 - x --------- equation (i)

$\frac{x}{y-2} = \frac{1}{2}\\\\ y-2 = 2x\\\\y = 2x + 2 ------equation(ii)$

Substitute y in equation (ii)

110 - x = 2x + 2

110 - 2 = 2x + x

108 = 3x

x = 108 / 3

x = 36

Therefore, the smaller number is 36

Listed following is a set of statements describing individual stars or characteristics of stars. Match these to the appropriate

mixas84 [53]

Answer:

1. The majority of stars in our galaxy -- B
2. very cool but very luminous -- A
3. not much larger in radius than Earth ---- C.
4. very hot but very dim ---- C
5. the Sun, for example --- B
6. found in the upper right of the H-R diagram -- A
7. a very hot and very luminous star --- B

Explanation:

The red giant is a luminous star with a mass in the late period of its stellar evolution and as the outer atmosphere inflated and is tenuous and maks the radius much larger and the temperature up to the 5000k.

While the main sequence is the continuous and a distinctive and is a continuous band of the stars appears in the stellar colors and the brightness. The majority of the stars in the galaxy are formed by these stars and the sun is an example.

While the white dwarf is degenerated and is composed of the hot and the dim stars these have a high density and mass.
