1. The right answer is AC (alternative current) generators.

AC current (which can be abbreviated as AC) is a periodic electrical current that changes direction twice per period and carries alternating amounts of electricity in one direction and the other1. An alternating current therefore has a continuous component (average value) zero.

2. The right answer is Repel, and attract.

The nucleus of an atom is an assembly of protons and neutrons concentrated in a very small volume and subjected to two different forces: the nuclear force and the electric force.

The electric force only acts on charged particles, attracting those which are of opposite signs and repelling those of the same sign. This "long" distance force allows the negatively charged electrons to be retained around the positively charged nucleus.

3. The right answer is electric circuit

An electrical circuit in the material sense is a simple or complex set of electrical or electronic components, including simple conductors, traversed by an electric current.

In the sense of circuit theory, an electrical circuit is an abstraction of material configurations, an arrangement of elements defined by mathematical relations, connected by ideal conductors.

4. The right answer is Volts and current.

Volt (V) is the unit of measurement of the electrical voltage in a circuit between a point A and a point B, obtained with a device called a voltmeter. It is to Alessandro Volta, Italian physicist and inventor of the electric battery, that we owe this name.

The ampere (A) is the unit of measurement of the intensity of an electric current, that is to say the flow of electrons in a conductor. André-Marie Ampère, the inventor of the electromagnet, gave his name to this unit.

5. The right answer is north pole.

The magnetic North Pole of the Earth is a unique wandering point on the surface where the Earth's magnetic field is pointing down. That is, the "dip" is 90 °. The needle of a compass points approximately towards this place (more or less approximately according to the place where one is, exactly the compass is tangent to the line of field).

6. The right answer is perpendicular.

In a cyclotron, the magnetic field is applied perpendicularly in an empty disk-shaped chamber, which contains two D-shaped semicircular electrodes. The rectilinear portions of these electrodes face each other. The flow of electrons or ions crossing a perpendicular magnetic field is subjected to a forceperpendicular to the direction of movement.

7. The right answer is current

A solenoid is a device consisting of an electric wire wound regularly in a spiral so as to form a long coil. Running through a current, the solenoid produces a magnetic field in its vicinity, and more particularly inside the helix where this field is almost uniform.

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.

[Chapter 3-4] A cross was carried out between the following two pureline parental strains:Parent 1: A/A; b/b; D/D; e/e; F/FParen

andrew-mc [135]

Answer:

Following the selfing of the F1 from the cross between the two parental strains, what proportion of the F2 individuals will phenotypically resemble either one of the two parental lines?

= 7.03% of F2 progeny will resemble parent 1

= 2.34% of F2 progeny will resemble parent 2.

Explanation:

Parent 1: AA; b/b; D/D; e/e; F/F

Parent 2: a/a; B/B; d/d; E/E; f/f

F1 Progeny: A/a; B/b; D/d; E/e; F/f

knowing that the F1 progeny is selfed, the possible gamete outcomes are:

ABDeF , ABDEf, ABdeF, ABdEf

AbDeF , AbDEf , AbdeF , AbdEf

aBDeF , aBDEf , aBdeF , aBdEf

abDeF , abDEf , abdeF , abdEf

All gametes are either eF or Ef (the two parental genotypes) and never EF or ef.

At the A, B and D loci, the F1 are heterozygotes. Therefore, in the F2 progeny, for each locus, 3/4 of the progeny will have the dominant trait while 1/4 will have the recessive phenotype. Further, 1/2 of all F2 progeny will have the haplotype eF and the other half will be Ef.

<u>Proportion of progeny resembling Parent 1: </u>

Parent 1 has the Phenoytpe AbDeF. As previously discussed, 3/4th of all F2 progeny has the phenotype A, 1/4th of F2 progeny has the phenotype b, 3/4th of F2 progeny has the phenotype D and 1/2 of F progeny has the phenotype eF.

Thus, the proportion of progeny resembling Parent 1

= 3/4 x 1/4 x 3/4 x 1/2 = 0.0703125

= 7.03% of F2 progeny will resemble parent 1.

<u>Proportion of progeny resembling Parent 2</u>:

Parent 2 has the Phenoytpe aBdEf. As previously discussed, 1/4th of all F2 progeny has the phenotype a, 3/4th of F2 progeny has the phenotype B, 1/4th of F2 progeny has the phenotype d and 1/2 of F progeny has the phenotype Ef.

Thus, Proportion of progeny resembling parent 2

= 1/4 x 3/4 x 1/4 x 1/2 = 0.0234375

= 2.34% of F2 progeny will resemble parent 2.
