Minchanka [31]

Answer:

Environmental impacts of particles, such as dust and  smoke, released from livestock production - impair the visibility, can lead to acid rain, degrade the ecosystem

Environmental impacts of greenhouse gases released from livestock  production - increase in atmospheric temperature

Explanation:

Environmental impacts of particles, such as dust and  smoke, released from livestock production -

Release of particles such as  dust and  smoke is referred to as particulate pollution. These particle makes the air unfit for .breathing. If humans inhale it, it will adversely affect the heart and lungs.

These particle impair the visibility, can lead to acid rain, degrade the ecosystem etc.

Environmental impacts of greenhouse gases released from livestock  production -

Green house gases will lead to increase in atmospheric temperature

You examine an epithelial cell (skin cell) and notice the chromosomes are visible however it appears there are two nuclei in the
krek1111 [17]

Answer:

The best explanation if we observe an epithelial cell with chromosomes are visible and two cell nuclei is that the cell has just gone through telophase but not cytokinesis (option b).

Explanation:

A somatic cell, when found in mitosis, exhibits the chromosomes distributed in both poles and the outline of two nuclei in the telophase phase, just before cytokinesis.

In mitotic telophase:

  • Chromatids, which are chromosomes, are found in the cell poles.
  • It initiates the formation of the nucleus membrane.
  • The chromosomes begin to turn into chromatin.
  • Disappearance of the mitotic spindle, duplication of organelles and cytoplasmic invagination.

The division and differentiation of the nuclei in telophase is called karyokinesis. Later, cytokinesis occurs, where the daughter cells are separated.

The other options are not correct because:

<em>     a and d. In the other phases described, </em><em><u>S and G1,</u></em><em> no chromosome distribution is observed at the poles.</em>

<em>     c. A somatic cell does not experience </em><em><u>meiosis</u></em><em>.</em>

Artyom0805 [142]
<span>Basically both operate by bouncing tiny particles or waves off of objects in order to make them visible. Electrons are smaller than light photons so we can see smaller objects clearly with electron microscopes. There are disadvantages though. First, color is a function of light wave frequency so we can't see electron micrographs in color. Color can be added artificially though by computer to differentiate structures, (think photoshop). Also, we cannot see electrons so we make them visible by bouncing them off a cathode ray screen similar to a TV set or computer monitor</span>
