Venous blood from the ankle travels and goes through tibial vein, popliteal vein, femoral vein, external iliac vein, common iliac vein, inferior vena cava to the heart (right side). From the heart to the right side of the brain, blood goes through the aorta and the brachiocephalic artery. The brachiocephalic artery the then divides into the right common carotid artery and the right subclavian artery and both supply the right side of the brain.
Answer:
Tyr Ile Leu Ala Thr Thr
Explanation:
In a DNA sequence, a pair of three bases form a codon that codes one particular amino acid in the protein. Proteins are consist of 20 amino acids and these amino acids are coded by a pair of three bases.
There are four bases in a DNA - Thymine (T), Adenine(A), Guanine(G) and Cytosine(C).
The given mutated DNA sequence will also code for some amino acid, that is as follows:
TAC - Tyr (Tyrosine)
ATC - Ile (Isoleucine)
TTG - Leu (Leucine)
GCG - Ala (Alanine)
ACG - Thr (Threonine)
ACT - Thr (Threonine)
Thus, The mutated DNA sequence TAC ATC TTG GCG ACG ACT codes for Tyr Ile Leu Ala Thr Thr.
A temperate forest is likely
to have numerous flowers from flowering
plants. Flowers are an evolutionary trend in flowering plants to attracts animals to
facilitate pollination. The flowers contain nectar that attracted birds, bees and other
nectar-sucking animals. The nectar is produced by nectaries
in hollow
tube in the flowers. Therefore for birds to access
the nectar they require to have long slender beaks as an adaptaition.
