When a newly formed cell enters into interphase and begins conducting metabolic functions, it is in _____.
Marta_Voda [28]

Answer:

The correct option is b. G1 phase. When a newly formed cell enters into interphase and begins conducting metabolic functions, it is in <u>G1 phase.</u>

Explanation:

The cell cycle comprises a whole series of events or phases that take place in the cell during its growth and division. A cell spends most of its time at the stage called<em> the interface</em>, and during this time it grows, duplicates its chromosomes and prepares for cell division. The cell cycle has different phases, which are called G1, S, G2 and M.

G1 phase is that in which the cell prepares to divide, during this phase, the cell grows rapidly, while performing routine metabolic processes. It also produces proteins necessary for DNA replication and copies some of its organelles in preparation for cell division. A cell normally spends most of its life in this phase. This phase is also known as Gap 1 phase and actively synthesize RNA and proteins.

G0 phase is a period or cycle of a cell where it remains in a resting state, in this phase mature cells that leave the cell cycle are placed.

G2 phase, during this stage, the cell makes the final preparations for its division.

Which statement best explains why Earth's lithosphere is broken into tectonic plates?
Nadusha1986 [10]

Answer:

( d ) The brittle lithosphere cracks under pressure from the moving asthenosphere.

Explanation:

~ The earth's crust refers to the outer layer of the planet earth . The surface of a planet is usually formed of less dense material than the deeper layers. Only 1/3 of the earth's crust is terrestrial , the rest is covered by oceans . The thickness of the earth's crust is between 10 to 30 miles.

The earth's crust, which is the upper part of the lithosphere , is divided into two layers. The top layer is continental , which is composed of granite . While under granite is a layer of hard rock called basalt .

On a semi-liquid planet , such as Earth , the earth's surface floats on top of the liquid inner layer. The crust seems to be often divided into pieces known as tectonic plates which due to the movement of molten magma beneath it, are able to move. This is a phenomenon of continental drift theory . In addition, collisions between two tectonic plates can produce volcanoes .

The Earth's crust is made up of rocks, minerals, soil and fossil fuels.

Metamorphic rocks that don’t have layers
Anuta_ua [19.1K]

Answer;

-Non-foliated metamorphic rocks

-Metamorphic rocks that don’t have layers are called non-foliated metamorphic rocks.

Explanation;

-Metamorphic rocks are rocks that go through heat and pressure and change form. They can be formed by pressures deep inside the Earth, by tectonic processes such as continental collisions, or when they are heated up by an intrusion of hot molten rock called magma from the Earth's interior.

-Foliated metamorphic rocks have a layered or banded appearance that is produced by exposure to heat and directed pressure, they include rocks such as gneiss, phyllite, schist, and slate.

-On the other hand,Non-foliated metamorphic rocks do not have a layered or banded appearance, they include rocks such as hornfels, marble, quartzite, and novaculite.
