Answer:

Abrasion

Explanation:

Mechanical weathering is generally called physical weathering where rocks are broken down physically. It means that the rocks are broken down into smaller pieces but the rocks' composition (chemically) is not changed.

There are different ways that rocks can be broken into smaller pieces physically and gravity helps can also cause it.

Abrasion is an example of mechanical weathering where rocks bump into each other and cause the rocks to breakdown because of the force of bumping into each other. Gravity plays a role when it comes to rocks on the mountain side.

When a rock on top tumbles down the side of the mountain, it bumps into other rocks along the way. Gravity is at play here because it pulls the rock downwards, causing it to tumble.

An object has a mass of 8.00 kg. what is the force due to gravity in the object

givi [52]

Answer:

Explanation:

When a mass of 8 kg is located on the Earth's surface, the magnitude of each of

the gravitational forces attracting the mass and the Earth toward each other is

(mass) x (acceleration of gravity on Earth) =

(8.0 kg) x (9.81 m/s²) =

78.48 kg-m/s² = 78.48 newtons (about 17 pounds 10.2 ounces)

Arrange the events in the life cycle of mosses in the flowchart below. Start the life cycle with the mature sporophyte stage in

labwork [276]

Answer:

Life cycle of a moss

Explanation:

LIFE CYCLE OF A MOSS FROM MATURED SPOROPHYTE STAGE

An embryo further develops into a pear-shaped sporangium, which is the *sporophyte stage of the plant*. The sporangium contains spore sacs, each of which is the spore mother cell that undergoes meiotic division to form four spores,The spores are released and germination

takes place giving rise to a protonema, which develops into a new gametophyte plant. The gametophyte generation or haploid phase of the moss is from the production of haploid spores after meiosis to the period just before fusion of the haploid antherizoid or haploid ovum. The sporophyte generation or diploid phase is from the diploid mother cells just before meiosis.

Examples of moss plants include Funaria hygrometrica, Polytrichum commune, Barbuda Indica.

Hydrothermal vents are usually located on the most bottom part of the ocean. A hydrothermal is created when there is a fissure in the planet’s surface underneath the ocean.

Carbohydrate layer on the plasma membrane includes all of the following except:

irinina [24]

Answer:

c) Gives a cell its distinctive characteristics

Explanation:

Carbohydrates perform two main functions in the cell's membrane: they participate in cell recognition and adhesion (cell-cell signaling or cell-pathogen interactions), they also have a structural role as a physical barrier.

Most of the carbohydrates linked to the membrane are in the form of glycoproteins oy glycolipids, these are the molecules that share information and recognize host cells. Glycocalyx is another way we find carbohydrates in the cell membrane, this layer has cell-adhesion molecules that enable cells to adhere to each other.

I hope you find this information useful! Good luck!
