(A)Humans have been changing the shape and color of fruits and vegetables since farming began about12,000 years ago.
Answer: the correct answer is A. ACTH
Explanation:
ACTH stands for Adrenocorticotropic hormone Adrenocorticotropic hormone (ACTH, also adrenocorticotropin, corticotropin) is an important component of the hypothalamic-pituitary-adrenal axis and is often produced in response to biological stress (along with its precursor corticotropin-releasing hormone from the hypothalamus). Its principal effects are increased production and release of cortisol by the cortex of the adrenal gland. ACTH is also related to the circadian rhythm in many organisms.
Answer:
F
Explanation:
tRNA are the RNA molecules that help decode the mRNA strand. On one end, They contain an anticodon which helps recognize the correct pairs in mRNA and on other end they contain amino acid. In this picture, letter F has both of these therefore it is tRNA.
Answer:
Elerochemical gradient
Explanation:This coccus during the process of chemiosmosis in oxidative phosphorylation during cellular respiration. It is the electrochemical gradient that provides the energy needed by ATPase Synthase for the phosphorylation of ADP tp ATP, necessary for ATP production
The electochemical gradient is due to gradient produced from the pumping of protons by the proton motive force(PMF) into the intrammenbrane space. from the matrix.The accumulation leads the the production of electrochemical gradients because the Protons diffuse across from higher gradient in the intramembrsne space into the lower concentration gradient the matrix.Therefore,energy is produced as the diffusion takes place.
The ETC, is the source of generation of PMF, which pumps protons across into the intramembrane, for the electrochemical gradients productions
Answer:
3. The equator receives more direct sunlight than the North Pole.
Explanation:
<h2>The equator is the longest latitude at 0°.</h2><h2>The equator isn't influenced any change when the earth revolves around the sun cause winter and summer. </h2><h2>That's why equator is warmer than north and south pole.</h2>
<h2>I hope you understood</h2>
