According to the information provided in the image the emergence of photosynthetic organisms contribute to the weathering of rock was

option B was the correct answer

what does weathering of rock refers to ?

Rock Weathering: Weathering is the transformation of rocks into more stable materials as a result of exposure to agents such as air, water, and organic fluids. No rock is impervious to weathering.

                                                         or

Weathering is the process through which rocks disintegrate and decompose in situ. It signifies that weathering is a static process. Weathering, as defined by C.D. Oilier (1969), is "the breakdown and modification of minerals near the earth's surface to produce products that are more in balance with freshly imposed physico-chemical circumstances."

The rock was formed when oxygen reacted with other elements to form earths crust which weathered the rock.

that is the oxygen that is produced from the photosynthetic process was reacted to the hydrogen that is present in the gases formed the water and that lead to the weathering of the rock.

a 0.1 kg slinky sits at the top of a staircase with 14 J of potential energy. How high is the staircase?
Bezzdna [24]

Answer: The staircase is 14.28 m high.

Explanation:

Given : Mass = 0.1 kg

Potential energy = 14 J

Potential energy is the energy occupied by the position of a substance. Therefore, formula for potential energy is as follows.

P.E = mgh

where,

m = mass

g = gravitational energy = 9.8 m/s^{2}

h = height of object

Substitute the values into above formula as follows.

P.E = m \times g \times h\\14 J = 0.1 kg \times 9.8 m/s^{2} \times h\\h = \frac{14 J}{0.1 kg \times 9.8 m/s^{2}}\\= \frac{14 J}{0.98 m kg/s^{2}}\\= 14.28 Js^{2}/ mkg          (1 J s^{2}/m kg = 1 m)\\= 14.28 m

Thus, we can conclude that the staircase is 14.28 m high.

Why is the classification species not considered a group? (1 point)
vitfil [10]

Each species is a separate type of organism.

  • A species is a group of creatures that share similar traits. The same species of organisms are capable of sexual reproduction as well as interbreeding and producing fertile offspring. It is a fundamental unit of taxonomy and classification.
  • The system is divided into seven categories: Kingdom, Phylum or Division, Class, Order, Family, Genus, and Species. Kingdom is the most inclusive category.
  • In a group, many types of an organism can be included even if they do not share the same traits. But species is a group of organisms that share similar traits.
  • For example, human beings are species as they are all alike in physical features, way of reproduction, etc. But the animal is considered a group because it included a variety of living beings.

Therefore, Each species is not considered a group.
