ValentinkaMS [17]3 years ago
7 0

Answer:

Energy can pass from one trophic level to the next when organic molecules from an organism's body are eaten by another organism. ... On average, only about 10% of the energy stored as biomass in one trophic level—e.g., primary producers—gets stored as biomass in the next trophic level—e.g., primary consumers

Answer:

"DRY MIX"

Dependent responding (variable) X axis

Manipulated independent (variable) Y axis

The drinks is the dependent variable because it "responds" to the temperature and is "dependent" on the temperature. The temperature determines the drinks sold-but the drinks sold doesn't determine the temperature.

Place all eight of these steps of the insulin signaling pathway in the correct order. The abbreviation PIP 2 is used for phospha
DedPeter [7]

Answer:

The correct insulin pathway is described as under:

2. Binding of insulin to the alpha subunit of the insulin receptor

8. Activation of insulin receptor tyrosine kinase

3. Phosphorylation of IRS proteins

6. Phosphorylation of phosphinositide 3-kinase (PI-3K)

4. Conversion of PIP2 to PIP3

7. Activation of PIP3-dependent protein kinase B (PDK1)

5. Glut4 receptors transported to the cell membrane

Explanation:

The insulin signaling pathway is described as under:

RTK (receptor tyrosine kinases) which is a receptor for insulin is an extracellular receptor but in contrast to other cell surface receptors it is catalytic in nature. In the absence of insulin (ligand), it is monomeric but as soon as it gets activated (activation occurs upon ligand binding), it undergo dimerization. It leads to auto-phosphorylation in it's tyrosine residue which subsequently leads to phosphorylation of tyrosine residue of other receptors. Such hyper-phosphorylated receptor have high affinity with enzyme/molecule like IRS protein which have SH2 domain . IRS down stream activates phosphinositide 3-kinase (PI-3K). This enzyme converts component of animal cell membrane PIP2 into PIP3. PIP3 also remains membrane bound but it has the potential to phosphorylate another enzyme named as PIP3-dependent protein kinase B (PDK1). Further, PDK1 leads to the activation of Akt or PK-B. Akt is a serine-threonine kinase which ultimately leads to the recruitment of Glut4 receptors on cell membrane for uptake of more and more glucose into the cell.

Note: Apart from this Akt also phosphorylates another protein named as FOXO which ultimately causes cell growth, Akt can also phosphorylate BAD protein so as to restrict cell apoptosis or we can say it leads to cell survival, Akt also leads to translation in a cell with the help of mTOR raptor etc.

Solnce55 [7]

Answer:

here ya go

Explanation:

A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest.
