Answer:
A: Plant Cells
Explanation:
the cell membrane is found in all living species, including plants.
Cephalization describes the process by which organisms develop a distinct head. The head of a cephalized organism contains a concentrated group of nerves, or brain, that controls the rest of the organism, as well as specialized organs for consumption and perception, like mouths, eyes and ears. Cephalized organisms exhibit a distinct division between parts of the body; they have a front, back, top and bottom. These animals comprise the bulk of animals that are encountered on a daily basis.
sea star following organisms exhibits cephalization
Answer:
The correct answer is -
gly-met-arg-phe-val-pro
Explanation:
The production of the amino acid chain or sequence from the desired DNA sequence is called the protein synthesis or central dogma that involves two processes, transcription and translation. Transcription is the process of transcribing the information encoded in the DNA sequence into a complementary mRNA sequence. The translation is the second process that involves the translation from mRNA to a specific amino acid.
mRNA sequence is complementary to the DNA
so, DNA - CCC-TAC-CGC-AA-CG-CC
mRNA - GGG-AUG-CGC-UUU-GUC-GG
and amino acid from the chart : gly-met-arg-phe-val-pro
Answer:
1. Ends of the respiratory branches are called alveoli.
2. C. To control blood flow to different areas of the body depending on activities
Explanation:
1. The trachea divides into left and right primary bronchi which in turn divide multiple times upon entering the lungs and make the bronchial tree.
The final branches of the bronchial tree are the terminal bronchioles that lead to alveoli. The alveoli are the balloon-shaped structures and serve as the site of gas exchange between the blood and inhaled air.
2. The opening and closing of sphincters of capillary beds regulate the direction of blood flow. The opening of sphincters allows the blood to flow into associated branches of capillary beds while closed sphincters direct the blood from arterioles to venules via thoroughfare channel.
This local change in blood flow is responsible for the autoregulation of blood flow to different tissues to match their respective metabolic demands. For example, during physical activity, more blood is directed to skeletal and cardiac muscles.
After miles of running and sprinting in intervals, the runner's muscle ache and feel fatigue due to anaerobic respiration taken place in the muscle cells.Anaerobic respiration in animal cell gives Carbon Dioxide and lactic acid as products. Due to the formation of lactic acid after running, muscles feel fatigue and ache.
I hope I helped you! ^^
