A prominence refers to a bright, large, gaseous feature projecting externally from the surface of the Sun, usually in a loop shape. Prominences are attached with the surface of the Sun in the photosphere and elongate outwards into the corona of the Sun.

The prominences are related to the discharge of the high energy constituents called a solar flare. These solar flares have been considered to influence electronic communication as their energy blends up the upper atmosphere of the Earth, making the radio transmissions weak and noisy.

Hence, the correct statements are prominences can disturb radio communications on Earth and prominences are loop-shaped.

Homologous chromosomes line up in the center of the cell

KonstantinChe [14]

Answer:

Metaphase I

Explanation:

Homologous chromosomes are paired to facilitate crossing over during prophase I of the meiosis I. This is followed by alignment of homologous chromosomes at the equator of the cell during metaphase I. The process is assisted by microtubules of spindle apparatus. The kinetochore microtubules of the spindle apparatus attach themselves to the kinetochores of chromosomes.

The two sister kinetochores of duplicated homologous chromosomes are attached to the opposite pole to align the homologous pair at the center of the cells. Metaphase I is followed by anaphase I during which homologous chromosomes move towards the opposite poles.

In what way do the membranes of a eukaryotic cell vary?

ser-zykov [4K]

Answer:

The Answer is Letter E.

Explanation:

<em>The way membranes of a eukaryotic cell vary is certain proteins are unique to each membrane. </em>

The eukaryotic cells also contain other membrane-bound organelles such as mitochondria and the Golgi apparatus, and in addition, some cells of plants and algae contain chloroplasts. Unlike unicellular archaea and bacteria, eukaryotes may also be multicellular and include organisms consisting of many cell types forming different kinds of tissue.
