Answer:

Anaphase: chromosomes are pulled apart

Explanation:

Anaphase is a very rapid phase of meiosis and mitosis where sister chromatids (during mitosis or meiosis II) or homologous chromosomes (during meiosis I) separate and migrate to opposite poles of the cell. In the image, the diagram represents mitosis (thus separation of sister chromatids).

During this phase, following a specific signal, the sister chromatids separate abruptly. They are then "pulled" by the "microtubules" towards the pole to which they are attached. Chromatids migrate rapidly at a rate of about 1 μm / min. Anaphase is usually divided into two distinct phases.

A spherical water drop 1.4 um in diameter is suspended In calm air due to a downward- directed atmospheric electic leld of magni

PtichkaEL [24]

Answer:

$N=1.5*10^{11}$ electrons en excess

Explanation:

We use the density of water equal to 1000 Kg/m^3, in order to find the mass and Force gravitational:

$m=\rho *Vol=\rho*4\pi*d^{3}/24\\ F=mg=g*\rho*4\pi*d^{3}/24=9.81*1000*4\pi(1.4*10^{-6})^{3}/24=1.41*10^{-14}N$

As the water drop is suspended in calm air, the Gravitational force is compensated with the electrical Force:

$F_{e}=mg=1.41*10^{-14}N$

But:

$F_{e}=Q*E=N*q_{e}*E$

We solve in order to find the number of electrons in excess at the water drop:

$N=F_{e}/(q_{e}*E)=1.41*10^{-14}/(1.6*10^{-19}*587*10^{-9})=1.5*10^{11}electrons$

The average latent heat of evaporation of water is 2.3 MJ/kg at 25oC-160oC. The heating value of a biomass material is 17 MJ/kg

mr Goodwill [35]

Answer:

Firstly the wet basis and dry basis are not the same. The wet basis involves measuments taken with consideration of the amount of moisture contained in a sample while in dry basis there is absence of water.
