During interphase, the cell copies its DNA in preparation for the second stage of meiosis.

Prophase is the first stage of cell division, in which the chromosomes become visible as paired chromatids and the nuclear envelope disappears.

Metaphase is the second stage of cell division in which the chromosomes become attached to the spindle fibers.

Anaphase is the third stage of cell division, in which the chromosomes move away from one another to opposite poles of the spindle.

Telophase is the fourth stage of cell division, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.

Cytokinesis is the division of a cell at the end of mitosis or meiosis that separates the cells into two individual daughter cells.

4. If index of refraction 1 is 1.5, index of refraction 2 is 2.0, and the angle of incidence is 45 degrees, what is the angle of
motikmotik

Answer: The angle of refraction is 32°

Explanation:

By snell law, we have that:

n₁*sen(θ₁) = n₂*sen(θ₂)

Where n₁ = 1.5

n₂ = 2.0

θ₁ = 45°.

then we want to find the angle of refraction.

1.5*sin(45°) = 2*sin(x)

x = Asin(1.5*sin(45°)/2) = 32°

Plasmodesmata can change in number, and when dilated can provide a passageway macromolecules

Plasmodesmata are essential for the intercellular transfer of both big informational macromolecules like proteins and smaller signaling chemicals in plant cells.

  • Plasmodesmata are membrane-lined structures that offer a high-conductance, aqueous channel for the transportation of information in the form of chemicals and macromolecules, such as transcription factors, from cell to cell.
  • The intimate interaction of the plasma membrane with the endoplasmic reticulum results in the formation of plasmodesmata.
  • The degree to which a particular cell acts as an individual or as a component of the entire organism is determined by the distribution and unitary conductance of plasmodesmata as well as other positional variables that affect development.
