Tissue is a group of cells that work together to perform a specific function.
Answer:
A healthy ecosystem consists of native plant and animal populations interacting in balance with each other and nonliving things (for example, water and rocks). ... Decomposers break down dead plants and animals, returning vital nutrients to the soil. Plants take up these nutrients, along with water, through their roots.
Explanation:
Hormone – biologically active molecule that is released into circulation from site of synthesis and acts at a distant sitecan be either hydrophilic (polypeptide hormone) or lipophilic (steroid) – biogenic amines can be eitherbinds specific receptor – on cell surface (hydrophilic hormones) or inside cell (lipophilic hormones)lipophilic hormones bind carrier proteins to travel in circulation; hydrophilic hormones travel freelycis-acting elements – DNA segments in the promoter region which bind trans-acting elementstrans-acting elements – molecules that impact downstream gene transcription when they bind cis-acting elements
Answer:
A) 5' AGCTAG 3'
Explanation:
DNA strands are antiparallel meaning that 3' to 5' has a complementary strand from 5' to 3'. This means that the last two answers can be eliminated because you can't have the 3' side pair up with a 3' side.
the other thing to remember is one of Chargaff's rules:
- A pairs with T
- G pairs with C
When writing a complementary strand's sequence, you must "convert" the letter in the original sequence to the letter that it is paired with by Chargaff's 2nd rule.
