If a species has 35 percent adenine in its dna, what is the percentage of the other three bases?
Basile [38]

Answer:

The percentage of other bases are: Thymine = 35%, guanine = 15% and cytosine = 15%.

Explanation:

There are four bases in DNA molecules, the bases are adenine, thymine, guanine and cytosine. The quantity of adenine and thymine are always equal, so also, the quantity of guanine and cytosine are always equal. Based on the information given in the question, Adenine = 35%, this implies that thymine too is 35%. The two bases added together give 70% , leaving only 30% for guanine and cytosine. Cytosine and guanine will share this equally and so each one of them will have 15%.

Apply The axes in the coordinate grid at the right represent the walls of a bedroom. One corner of the room is at the origin. Wh
Anestetic [448]

The axes in the coordinate grid on the right represent the walls of a room. the distance from that corner of the room to the corner of the furthest bed is 11 axes. A coordinate grid has two perpendicular lines, or axes (pronounced AX-eez), labeled just like number lines. The horizontal axis is usually called the x-axis. The vertical axis is usually called the y-axis. The point where the x- and y-axis intersect is called the origin.

<h3>How many axes are in a coordinate system?</h3>

The coordinate plane has two axes: the horizontal and vertical axes. These two axes intersect one another at a point called the origin.

<h3>What are the XY and Z axes?</h3>

The x axis is in the plane of the screen and is positive toward the right and negative toward the left. The y axis is in the plane of the screen and is positive toward the top and negative toward the bottom. The z axis is perpendicular to the screen or keyboard, and is positive extending outward from the screen.

With this information, we can conclude that the distance from that corner of the room to the corner of the furthest bed is 11 axes.
