Answer: Option (D)

Explanation: In case of an occluded front, the warm front is totally replaced by the cold front, in which the warm air masses are completely vanished. And due to the relatively cold temperature of the cold front, there occurs frequent changes in the different weather forming conditions.

                         Whereas, in case of a cold front, the cold air masses becomes much mobile and enters the region of warm air and due to its higher density it generally remains in contact with the ground surface and also pushes the warm air to rise up. Due to this, often a variety of clouds are formed resulting thick clouds, thunderstorms and lightening.

What are the steps in filament theory
Inessa [10]

Answer and Explanation:

The steps of the sliding filament theory are:

Muscle activation: breakdown of energy (ATP) by myosin.

Before contraction begins, myosin is only associated with a molecule of energy (ATP), which myosin breaks down into its component molecules (ADP + P) causing myosin to change shape.

Muscle contraction: cross-bridge formation

The shape change allows myosin to bind an adjacent actin, creating a cross-bridge.

Recharging: power (pulling) stroke

The cross-bridge formation causes myosin to release ADP+P, change shape, and to pull (slide) actin closer to the center of the myosin molecule.

Relaxaction: cross-bridge detachment

The completion of the pulling stroke further changes the shape of myosin. This allows myosin and ATP to bind, which causes myosin to release actin, destroying the cross-bridge. The cycle is now ready to begin again.

The repeated cycling through these steps generates force (i.e., step 2: cross-bridge formation) and changes in muscle length (i.e., step 3: power stroke), which are necessary to muscle contraction.

Many receptor tyrosine kinase pathways have mapk as a downstream signaling component. mapk can phosphorylate target proteins. wh
Lapatulllka [165]

A protein kinase that is specific to the amino acids serine and threonine is known as a mitogen-activated protein kinase (MAPK or MAP kinase; also known as a serine/threonine-specific protein kinase).

<h3>Mitogen-activated protein kinase :</h3>

A small number of cell surface receptors can ultimately generate a large intracellular response due to activation of kinase cascades.

In order to trigger an appropriate physiological response, such as cellular proliferation, differentiation, development, inflammatory reactions, and death in mammalian cells, MAPK pathways relay, amplify, and integrate information from a variety of stimuli.

Tyrosine phosphorylation, specifically numerous tyrosines on each RTK in the dimer, is how cross-linking triggers the tyrosine kinase activity in these RTKs. The term "cross-phosphorylation" refers to this action.

The activation of a MAPKKKK or MAPKKK by stimulation of plasma membrane receptors is the initial stage of signal transduction. The MAPKKK then phosphorylates two serine or threonine residues in the S/T-X5-S/T (X is any amino acid) motif of its activation loop, activating a downstream MAPKK.

What cell parts are common to all of these cells?<br><br> Use complete sentences.
Natalka [10]

Answer:

<em>between </em><em>an </em><em>animal</em><em> </em><em>cell </em><em>and </em><em>a </em><em>plant </em><em>cell </em><em>there </em><em>are </em><em>some </em><em>parts </em><em>that</em><em> </em><em>are </em><em>similar</em><em> </em><em>and </em><em>carry </em><em>out </em><em>the </em><em>same </em><em>function </em><em>like:</em>

<em>both </em><em>have </em><em>a </em><em>cell </em><em>membrane</em><em> </em><em>which </em><em>selects </em><em>what </em><em>goes </em><em>in </em><em>the </em><em>cell.</em>

<em>both </em><em>have </em><em>cytoplasm</em><em> </em><em>which </em><em>holds </em><em>the </em><em>protoplasm(</em><em>the </em><em>living</em><em> </em><em>part </em><em>of </em><em>the </em><em>cell)</em>

<em>both </em><em>have </em><em>a </em><em>nucleus</em><em> </em><em>which </em><em>carries </em><em>out </em><em>all </em><em>cell </em><em>activities</em><em> </em><em>and </em><em>holds </em><em>threads </em><em>of </em><em>DNA </em><em>called </em><em>chromosomes</em>

<em>both </em><em>have </em><em>a </em><em>mitochondria</em><em> </em><em>which </em><em>is </em><em>the </em><em>power </em><em>house</em><em> </em><em>of </em><em>the </em><em>cell</em>

<em>both </em><em>have </em><em>golgi </em><em>bodies </em><em>which </em><em>modify</em><em> </em><em>and </em><em>carry </em><em>proteins</em><em> </em><em>from </em><em>sites </em><em>of </em><em>synthesis</em><em> </em><em>to </em><em>sites </em><em>of </em><em>reaction</em>
