yKpoI14uk [10]

The appropriate response is the second one. Parallel fibers emerge from granule cells in the cerebellar cortex. Granule cells are little and exceptionally various. They are thought to make up the same number of as half of the neurons in the cerebrum. Granule cells have axons which ascend and afterward fan out into parallel filaments. These filaments meet the Purkinje cell dendrites.

Why are some secondary consumers carnivores,while others are omnivores

ivanzaharov [21]

Some other secondary consumers are carnivores and others are omnivores because they also eat both plants and meat. For example Human, human are secondary consumers, and human eat both plants and meat. There are also other animals that are considered as omnivores.

<h2>Homologous</h2>

Explanation:

<em>Two or more species share a unique physical feature,</em> for example, an unpredictable bone structure or a body plan, they may all have acquired this component from a typical predecessor.
Physical highlights shared because of developmental history (a typical progenitor) are said to be homologous.
<em>The front flippers of whales and the forelegs of four-legged vertebrates like canines and crocodiles are completely gotten from the equivalent tribal tetrapod structure.</em>

NeX [460]

No lesions in the mouth and throat
Weight increase of 1 lb over 3 days Correct
Temperature change from 100.2° F to 99.2° F
Capillary refill slowing from 2 seconds to 3 seconds
Weight increase of 1 lb (0.45 kg) over 3 days
Rationale: Vomiting results in fluid volume deficit. The most accurate method of evaluating fluid volume increase (the desired outcome) is weight. A temperature decrease is not reflective of fluid volume increase. Increasing capillary refill time is indicative of a fluid volume decrease, not an increase. The absence of mouth ulcers would allow the child to drink without pain but does not reflect a fluid volume increase.

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.
