Answer:

It is known by the name of gestation

Explanation:

Gestation or gestational age is the period of time between conception and birth. At this time, the baby grows inside the womb of his mother. Gestation or gestational age is measured in weeks, for example, a normal pregnancy can be from 38 to 42 weeks.

Babies born before week 37 are considered premature and if they are born after week 42 they are called post-mature.

Which of the following statements about plankton or nekton is NOT correct?
Oduvanchick [21]

Answer:

C. All plankton are closely related to plants.

Explanation:

Plankton are organisms found in water that exist in a drifting state. They are too small or weak to swim on their own, so they let the current or tide carry them. They are usually microscopic but include larger species as well, such as some crustaceans and jellyfish.

Phytoplankton are autothrophic plankton. This means that they produce their own food. They are primary producers and closely related to plants.

Zooplankton are heterotrophic plankton, which means that they feed on other organisms. They are animals and aren't closely related to plants.

Nekton are organisms found in water that swim actively.

Based on this information, we can conclude that statement C is the only incorrect statement.

_______________ refers to the tendency of a foundation material (such as soil) that is water-logged to lose its internal cohesio
dybincka [34]

Answer:

<u>Liquefaction</u> refers to the tendency of a foundation material (such as soil) that is water-logged to lose its internal cohesion and mechanically fail to provide support during earthquake shaking.

Explanation:

Liquefaction occurs when an unbound material (usually sand), which is saturated in water, loses its resistance to shear due to intense and rapid vibration (earthquake), which breaks its granular structure by reducing its inter-granular pressure and flow like a liquid because of an increase in pressure.

Liquefaction usually manifests itself in loose, saturated and non-cohesive soils, formed by young deposits of sands and sediments of similar particle sizes. If the soil is dense there will be less chances of liquefaction. Older deposits, in general, are more dense and cohesive. At higher density, more interstitial pressure is needed for liquefaction to occur.

The placement of prokaryotes into major clades within the domains Archaea and Bacteria has been based on __________.
Alja [10]

Answer:

Molecular evidence

Explanation:

Earlier archaea were considered as bacteria because they show some similarities with bacteria like binary fission as mode of reproduction, lack of a nucleus, etc.

Later Carl Woese separated bacteria in a different domain and divide prokaryote into two domains called bacteria and archaea. He separated archaea from bacteria on molecules evidence.

He compaired rRNA sequence between bacteria and archaea and observed that they both differ in rRNA sequence which allowed him to make a separate domain for archaea.
