Answer:

B. The cell wall and vacuole function to maintain the structure of plant cells

С. Chloroplasts allow the cell to store energy, and mitochondria release energy for the cell

E. Molecules can enter the cell by passing through the cell membrane and may take part in chemical reactions within the cytoplasm

Explanation:

Homeostasis, which is key to the survival of an organism, is the ability of a living organism's cell to maintain a stable internal environment despite changes to the external environment. Cell structures/organelles interact with one another in order to maintain homeostasis as follows:

- The cell wall and vacuole function to maintain the structure of plant cells. The cell wall is responsible for the rigidity of the plant cell while the water content of the vacuoles make the cell turgid.

- Chloroplasts allow the cell to store energy in the bonds of the glucose molecules that form as a result of the photosynthesis that occurs in the CHLOROPLAST while the mitochondria release energy for the cell due to the cellular respiration process that breaks down the glucose molecules to release ATP.

- Molecules needed by the cell can enter the cell by passing through the cell membrane and may take part in chemical reactions within the cytoplasm.

Determine whether each example represents continental drift or sea floor spreading.
laila [671]

Answer:

Sea floor spreading-> <u><em>Oceanic ridge and Magma pushing two plates apart</em></u>

Continental drift-> <u><em>Concept of pangaea and Oceanic plates sliding under continental crust</em></u>

Explanation:

Due to the divergent plate movement, the magma come out to the surface, forming the mid oceanic ridge and this separation of plates on the sea floor is known as the sea floor spreading. The magma here pushes the two plates to move apart because of the convection current that generates in the mantle. One example of mid oceanic ridge is the Mid-Atlantic Ridge.

  Continental drift refers to the slow and gradual movement of the lithospheric plates over the viscous asthenosphere layer. This motion of continents takes place because of the plate tectonic movement. Due to this plate motion, the denser plate gets subducts beneath the less denser plates. For example, the oceanic crust when collides with a continental crust, it gets subducted because of its higher density. The great supercontinent "pangaea" also formed and separated due to this plate motion.

1. A rock sample has a mass of 16 grams:
Morgarella [4.7K]

Answer:

(3) 4 cm' and 2.0 g/cm3

Explanation:

Given:

volume= V= 8 cm³

mass= m= 16 g

The density is the mass per volume of a substance, so the density of the rock is:

density= d= 16 g/8 cm³= 2 g/cm³

When we cut the rock in half, we have a half volume and a half mass:

V= 8 cm³/2= 4 cm³

m= 16 g/2= 8 g

But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:

d = m/V= 8 g/4 cm³= 2 g/cm³
