Answer:

north pole area

Explanation:

1. The north pole (very northern canada greenland and russia) is a big part of the world, but it's growing smaller

2. It's all mostly ice, so barely any trees

3. SUPER cold there, so it doesn't get warmer than 50 f or 10 c

5. The north pole area's ocean is called the Arctic Ocean

6. the aurora lights, or the Northern lights happen there too.

The y-shaped site at which a double-stranded molecule of dna is separated into two single strands for replication.
aleksandrvk [35]

The Y shaped structure with active region present is called replication fork

The separation of the 2 single strands of DNA creates a ‘Y’ form referred to as a replication ‘fork’. the 2 separated strands will act as templates for making the new strands of DNA.

LEADING STRAND

one of the strands is oriented in the 3’ to 5’ path (toward the replication fork), this is the main strand?. the other strand is oriented inside the 5’ to 3’ direction (away from the replication fork), that is the lagging strand?.

because of their extraordinary orientations, the 2 strands are replicated in a different way: A small piece of RNA called a primer (produced by means of an enzyme referred to as primase) comes along and binds to the end of the leading strand. The primer acts as the place to begin for DNA synthesis.

DNA polymerase? binds to the leading strand after which ‘walks’ alongside it, including new complementary? nucleotide? bases (A, C, G and T) to the strand of DNA within the 5’ to 3’ direction.

This form of replication is referred to as continuous

LAGGING STRAND

Several RNA primers are made by means of the primase enzyme and bind at numerous points alongside the lagging strand.

Chunks of DNA, known as Okazaki fragments, are then introduced to the lagging strand also in the five’ to a few’ path.

This sort of replication is known as discontinuous as the Okazaki fragments will want to be joined up later.

Once all the bases are matched up (A with T, C with G), an enzyme referred to as exonuclease strips away the primer(s). The gaps wherein the primer(s) were are then filled by but extra complementary nucleotides.

The brand new strand is proofread to make sure there are no errors inside the new DNA series.

eventually, an enzyme referred to as DNA ligase? seals up the sequence of DNA into two non-stop double strands.

The end result of DNA replication is two DNA molecules consisting of 1 new and one old chain of nucleotides. That is why DNA replication is described as semi-conservative, 1/2 of the chain is part of the unique DNA molecule, half is ultra-modern.

Following replication the brand new DNA routinely finishes up into a double helix.

Global air circulation cells move air _____.
tino4ka555 [31]

Global air circulation cells move air "clockwise in the Northern hemisphere and counterclockwise in the Southern hemisphere".

<u>Answer:</u> Option B

<u>Explanation:</u>

Global circulation is defined as the global connection of winds, through which the requisite heat transport  from tropical latitudes to polar latitudes carried out. Each hemisphere comprises with three cells, such as Hadley, Ferrel and Polar cell, air circulation take place in this through the complete depth of the troposphere.

The worldwide circulation cells allow passage of air in clockwise pattern in the northern hemisphere while in southern hemisphere circulate in counter-clockwise pattern from equator to poles but in different directions and at different latitudes.

Economic importance of tilapia fish
dezoksy [38]

Answer:

Tilapia is one of the most productive and internationally traded food fish in the world. The production of farmed tilapia is among the fastest expanding food sectors in the world. Nile tilapia ( Oreochromis niloticus) is the most cultured freshwater species among the farmed tilapia and contributes about 71% of the world total tilapia production.

Tilapia is one of the most important farmed fish species worldwide (FAO 2018) and an important source of protein (Fitzsimmons 2000;Hai 2015). Due to its sequenced genome (Conte et al. 2017), easy reproduction, efficiency in adapting to diverse diets, high resistance to diseases and handling practices, and high tolerance of a wide variety of husbandry conditions, it is considered an ideal model in toxicological research.
