The t tubule contributes to muscle movement because it _________ .

inessss [21]

Answer:

The t tubule contributes to muscle movement because it helps in triggering or initiation of the action potential inside the muscle cells.

Explanation:

As, there are number of structures of which activities are required to attain specific posters for the animal body and they play a vital role in making any physical activity either very fast or too slow in nature.
And along with this the chemical balance always fluctuates due to the requirement of locomotion or change in posters for the animal's body, as the T tubule has other cellular structures such as the sacromere and fibers which plays a great part in the as whole physical activities of the animal body.

A cylindrical tin full of engine oil has a diameter of 12cm and a height of 14cm.The oil is poured into a rectangular tin 16cm l

galben [10]

Answer:

Depth = 9 cm

Explanation:

First, calculate the volume of the cylindrical tin.

Mathematically, that would be the following:

$V = \pi * r^{2} * h$

Now, r = d/2 = 12/2 = 6 cm

h = 9 cm

Therefore, the volume will be:

V = 22/7 * 14 * 6^2 =1,584 cm^3

Now, to find the the depth of the tin, we have to realize that the content of the cylinder should fill in the tin to a particular height.

As we don't have the height of the tin so let's suppose it x, now it means that

l * b * h = 16 * 11 * x = 176x

Therefore, the depth would be:

176x = 1584

x = 1584 / 176 = 9 cm

The lagging strand is characterized by a series of short segments of DNA (Okazaki fragments) that will be joined together to for

scZoUnD [109]

Question is incomplete. Complete question has been attached.

Answer:

A) DNA polymerase is a directional enzyme that synthesizes leading and lagging strands during replication.

Explanation:

DNA polymerase synthesizes the new DNA strand from the template strands. Both the strands in a DNA molecule act as templates, however both of them have different orientation. It was observed that 3'-5' template DNA produced a new DNA strand continuously in one step. However, 5'-3' template produced new DNA strand in fragments which were joined together later. This observation gave the idea that DNA polymerase is a directional enzyme. It synthesizes DNA in 5'-3' direction so 3'-5' template gave rise to a continuous DNA segment. However, for 5'-3' template, DNA polymerase had to synthesize in opposite direction i.e. 3'-5' which was not possible directly. So the enzyme replicates it in short separate fragments which are later joined by DNA ligase.
