Answer:
While all of the individual characteristics of carnivorous plants can be found in other plants, when they are all combined in the same plant the organism is truly unique, a carnivorous plant whose modified leaves can trap and digest prey lured to the plant. The digested materials are utilized by the plant for its growth and development
Explanation:
Answer:
The correct answer is "C. Cave fish have evolved degenerated eyes because they have no use for vision in dark, underwater caves."
Explanation:
All of these statements about organism adaptation to its environment are true, but the real reason why cave-fish are blind is not because there's no use for their eyes in the dark, but because being blind saves them energy, as using one's vision requires the activity of photoreceptive cells and neurons, and underground caves are lacking in both food and oxygen.
Longitude is used to measure distances in degrees from the Prime Meridian. The correct option among all the options that are given in the question is the second option. The main purpose of longitude is to determine the east and west position of a point based on its geographical coordinate. I hope the answer helps you.<em />
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.
If this is for the scientific process unit, the answer is passing laws to prevent certain types of scientific research. I know because I had this question in biology.
