Answer:
The mRNA strands go to the cytoplasm to meet ribosomes so protein synthesis can start.
Explanation:
In protein synthesis, the first step is to <em>synthesize messenger RNA</em>, mRNA. The coping process of the DNA section for the desired protein is called <u><em>transcription</em></u>, and it happens in the <em>nucleus</em>. After that, it occurs <em><u>translation</u></em>, when the formed <em>mRNA moves to the </em><em>cytoplasm</em> through the nucleus membrane pores. Protein synthesis is initiated in the cytoplasm when mRNA meets a free ribosome, the primary structure for protein synthesis. Ribosomes are made of <em>protein and ribosomal RNA</em> and can be found in the r<em>ough endoplasmic reticulum</em> or floating in the <em>cytosol</em>. They read the mRNA code and add the correct amino acid using <em>transference RNA</em> to build the protein. mARN has a <em>start and end codon</em> that tells where to start and stop adding amino acids. When the ribosome reaches the end codon, it means that protein synthesis is finished. The new protein is driven to the rough endoplasmic reticulum and translocated to the lumen. Once there, the protein suffers a few modifications, one of them is <em>folding</em> to become functional. Finally, protein is transported by vesicles to the Golgi complex, and from there to its final destiny.

Answer:
thermoregulation and hormone transport
Explanation:
Homeostasis is the state of body in which body undergoes several chemical or physical changes to maintain the internal changes affected by external factors.
All systems in the body undergo different processes to maintain homeostasis and so Cardiovascular system maintain homeostasis through thermoregulation and hormone transport.
Cardiovascular system undergoes thermoregulation, in which heat is exchanged between the internal body organs, tissues and skin to maintain internal body temperature affected external thermal loads.
Cardiovascular system are responsible for blood circulation throughout the body and the blood transport hormones to different body organs or tissues. Hormones are chemical messenger that regulate behavior of different organs. All the endocrine glands secret hormones and release them into blood and then blood circulation transport them to suitable tissue for proper functioning.
Hence, the correct option is thermoregulation and hormone transport.
Answer: Option A. Decrease in pH across the inner mitochondrial membrane.
Explanation:
ATP synthase is a mitochondrial enzyme present in the inner membrane that catalyse the production of ATP from ADP and phosphate which is driven by protons present in the gradients of electron transport chain.
When ATP synthase is inhibited by metabolic poison, it will cause a decrease in the pH of the space between the mitondondrial membranes.
