<u>Answer:</u>
<em>Six centromeres are observed in a prophase cell from an insect, there are </em><u><em>20 pairs of chromosomes present</em></u><em>. </em>
<u>Explanation:</u>
<em>Centromeres is defined as the part of the DNA</em> which are held responsible for the directional changing of chromosomes.
And these chromosome gets divided into <em>2 daughter cells while undergoing the process of mitosis and meiosis. </em>
<em>Chromosome is basically defined as a thin structure</em> as of a threadlike which is made out of nuclei acid and protein which is <em>located at the nucleus of various living cells</em>
we aren't given options but in order from longest to shortest it is radiowaves, microwaves, infared,visible light, ultraviolet, x rays, gamma rays
Mitochondria produce ATP, energy that is vital in aerobic cells. Therefore, I believe this is why they can be considered as power plants.
From the pith outward, if you looked at a cross-section of a eudicot plant stem, you would see Xylem, vascular, cambium, and phloem in that order. The vascular cylinder divides the ground tissue into two discrete areas and is structured in a ring in eudicot stems.
The pith refers to the area of ground tissue that is included within the vascular cylinder. In general, eudicots possess three or more of the following traits: There are 2, 4, or 5 flower parts, or multiples of 4 or 5, and leaves have netted venation (pinnate or palmate). A ring of stem vascular bundles surrounds the pith, and seeds have two seed leaves (cotyledons).
As a result, we can assert that if you cut a cross-section of a eudicot plant stem, Xylem, vascular, cambium, and phloem in that order, you will find various plant tissues from the pith outward.
