Mountains formed by two colliding continents often contain marine _______ rock

1 answer:

4 0

The correct answer is Marine Sedimentary Rock. This means that when they collide, usually mountains come from out of the sea and move vertically up. This means that sedimentary marine rocks eventually become non-marine rocks since they're not in the sea anymore so they can be found on such mountains.

I'm pretty sure:

a) pepsin optimal pH: 3 and lipase optimal pH:8

b) No, because the stomach needs to be acidic and have an acidic pH but lipase is considered alkaline because its optimal pH is between 8-14 meaning it's an alkaline.

Not sure if this is any help but I hope it helped a little bit! :)

The answer is C. inbreeding

İnbreeding results in homozygosity, which can increase the risk of the koalas being affected by the genetic disorder.

The most primitive cells are prokaryotic. They are simple, with no organelles and no nucleus. Animal and plant cells are eukaryotic, but they express some differences such as the cell wall, chloroplasts, or centrioles.

---------------------------------------------

BACTERIA CELLS

Bacteria are prokaryotic cells.

Prokaryotic cells lack a nucleus, nucleolus, and organelles.

They only present plasmids, ribosomes, and genetic material in their cytoplasm.

DNA not surrounded by membrane

They have a cell wall that protects the cell and a cell membrane that surrounds the cytoplasm. Some of them can also present a capsule.

Some of them have flagellum.

These organisms are capable of inhabiting places with extreme temperature, salinity, acidity, or pH, among others.

ANIMAL AND PLANT CELLS

Both the animal and plant cells are eukaryotic.

They carry their genetic material in the nucleus and mitochondria.

Organelles are located in the cytosol, and both of them are surrounded by a protector cell membrane.

However, they have some differences:

⇒Cell wall : A rigid structure that provides support and protection.

• Animal cells do not have a cell wall. They are only surrounded by the cell membrane, which is flexible so they can adopt different shapes.

• Plant cells have a wall, so their shape is usually prismatic and regular. The cell wall is composed mainly of cellulose.

⇒ Chloroplast: these are organelles that accumulate chlorophyll.

• Animal cells do not have chloroplasts because they do not photosynthesize.

• Plant cells have chloroplasts, and they are in charge of the photosynthesis process that allows plants to release oxygen. These organelles use solar light as the source of energy.

⇒ Vacuoles:

• Animal cells have many and small vacuoles whose function is to store water, ions, and waste intracellular substances.

• Plant cells have a unique big-sized vacuole that might occupy almost 90% of the cell. Their principal function is to store water and keep the turgidity. When the vacuole gets empty, the plant loses rigidity.

⇒ Other differences are:
