Answer:
168 toads

2 toads/ 1 sq m
84(2) = 168

Answer:
3'-TTACGATG-5'
Explanation:
The DNA sequence is in couples where A is united T and G is united C, so what we do is replace in the complementary sequence the original nucleic acids, remember A-T, G-C.
5'-AATGCTAC-3'
3'-TTACGATG-5'
To remember: the DNA sequence is 5'-3' in one sequence and its complementary is inverse, what means it goes 3'-5'.
Also the T-A is united by 2 hydrogen bonds, and G-C is united by 3 hydrogen bonds.
White blood cells or WBCs are also known as leukocytes and these are the cells of the immune system. They serve as the soldiers inside our body that fight against infectious diseases and foreign invaders. WBCs are classified into different types. Some of them have multi-lobed nuclei, specifically, the neutrophils. It is the most abundant WBC in the body and they defend against bacterial and fungal infection. They have a multi-lobed nucleus, which consists of three to five lobes connected by slender strands. These multi-lobes are used for phagocytosis. Hope this answer helps.
