Active transport. it's the only method of transfer of material that is again concentration gradient

TCTCG and AGAGC are the perfect pair.
Option A
<h3><u>Explanation:</u></h3>
DNA is the genetic molecule of a living cell. The DNA stores genetic information of the species inside itself by means of particular pattern or sequence of nitrogen bases called as gene. The gene is comprised of the particular sequence of nitrogenous bases which are four in number - adenine, guanine, thymine and cytosine.
The nitrogen bases are present in both the strands of DNA and they have complementary relationship between them. The adenine forms hydrogen bonds with thymine and guanine pairs with cytosine.
Here the sequence of one strand is given as TCTCG. So according to the complementary pairing process, the opposite strand must have the sequence of AGAGC to maintain the structure.
Answer: <span>B) Plant trees along canals and roadways on their property to filter runoff and prevent soil erosion
--------
The roots of trees help prevent the soil from being easily eroded by holding the soil in place and taking up the water. The other choices, A, C, and D would cause further erosion by removing objects that would stop the rain or by aiding erosion due to gravity.

The pectoral girdle articulates with the axial skeleton only at the Sternoclavicular ligament<span>. The pectoral girdle connects the upper limbs to the axial skeleton and serves as the attachment site for the muscles of the upper back, chest and neck. The clavicle is the only long bone that lies in a horizontal position in the body. it has three regions; the medial end, the lateral end, and the shaft. The medial end has a triangular shape and articulates with the manubrium portion of the sternum. This forms sternoclavicular joint, which is the only bony articulation between the pectoral girdle of the upper limb and the axial skeleton. </span>
