Which statement is true about the layers of the Earth? * 1 as temperature and pressure increases, density increases 2 As tempera

nignag [31]

Answer:

1. As temperature and pressure increases, density increases

Explanation:

The earth is composed of three main layers: Crust, Mantle and Core. The density or mass per unit volume of the earth's layers increases as one moves from the surface towards the interior of the earth known as the core. Also, there is an increase in pressure and temperature as depth increases. There are three main sources of heat in the earth's core: (1) conserved heat from when the planet formed and coalesced, (2) heat due to friction caused by denser core material sinking to the center of the planet, and (3) heat from the decay of radioactive elements.

The earth's core is composed almost entirely of the metals, iron and nickel. The core has an inner solid layer and a molten outer core. Iron and nickel are both very dense metals, so the core of the earth is very dense and the density increases with depth with the inner core being the most dense layer of the earth.

Phoenix [80]

Answer:

SER, they are capable of synthesizing testosterone of Adrenocortical cells.

Explanation:

Adrenal smooth microsomal cells are enriched in smooth endoplasmic reticulum SER, membranes of which contain high levels of translocation apparatus and oligosaccharyltransferase complex proteins. STEROID-SECRETING CELLS are characterized by abundant smooth endoplasmic reticulum (SER). These cells synthesize cholesterol as a precursor for steroid hormones or take up this substrate from plasma lipoproteins. Many of the enzymes for sterol and steroid synthesis are localized in the smooth-surfaced endoplasmic reticulum. This organelle is particularly prominent in cells of the inner zones of the adrenal and fluctuates in amount and configuration in response to hormonal stimulation and sterol levels.

How does the foot of a bivalve differ from the foot of a cephalopod, or the foot of a snail? In what ways do these differences r

stira [4]

Answer:

Bivalve- Wedge shaped foot

Snail- Large and flat foot

Cephalopod- Foot is modified into siphon.

Explanation:

Molluscs are predominantly marine animals with a soft body,however,they are known to inhibit fresh water as well as terrestrial habitat.

They possess a *muscular foot*,which is used for *locomotion and anchorage*,they vary in shape and function depending on the type of mollusc.

MODIFICATION OF FOOT IN MOLLUSCS:

Bivalve- Foot is usually wedge shaped

Snail- Foot is large and flat

Cephalopod: Foot is modified int a siphon( a tube-like organ)

ADAPTATIONS OF FOOT IN MOLLUSCS

1)Bivalves have pointed retractable foot(wedge foot) that protrudes from the wheel and is adapted for *moving or burrowing*.

2)Snail have a mucus-laden muscular foot adaptation,that reflexes and contracts allowing movement(*crawling*) in water and terrestrial habitats

3)The foot of cephalopod is adapted for *moving* about by a kind of jet propulsion in water.
