Introduction:
Embryogenesis is the development of a fetus occurs. In this period all organs begins to develop and start functioning. Embryogenesis occurs after fertilization. When sperm meet to egg to form zygote then zygote starts dividing its cells to form blastula than organogenesis where organ starts to develop.
Answer to Problem 1PL
Correct answer:
The correct answer is an option (b) Development of the embryo and fetus progresses from cephalic toward caudal.
Explanation of Solution
Explanation/justification for the correct answer:
Option (b) cephalic is an embryo head. Caudal is an embryo tail. During the gastrulation period, the development starts from the head and ends with tail and orientation from front to back occurs. So, the correct answer is an option (b).
Explanation for incorrect answer:
Option (a) Development of the embryo and fetus progresses from medial toward lateral. The development of an embryo always occurs from head to tail not from medial to lateral. So, this is an incorrect option.
Option (c) Development of the embryo and fetus progresses from anterior toward posterior. The development of a fetus always starts from head to tail and front to back. So, this is an incorrect answer.
Option (d) Development of the embryo and fetus progresses from inferior toward a superior. The development occurs from head to tail not from inferior toward a superior.

- We will be starting a group project next week where you and your group will research and ultimately present on a current research article related to the biology of a pathogen that infects humans. The article could be about the pathogen itself, the disease process related to the pathogen, the immune response to the pathogen, vaccines or treatments that affect the pathogen, or other biology-related study about the pathogen. I recommend that you choose a pathogen that is currently interesting to researchers, so that you will be able to find plenty of articles about it. Avoid choosing a historical disease that no longer circulates. List 3 possible pathogens or diseases that you might want to do for your group project.arrow_forwardnot use ai pleasearrow_forwardDNK dagi nukleotidlar va undan sintezlangan oqsildagi peptid boglar farqi 901 taga teng bo'lib undagi A jami H boglardan 6,5 marta kam bo'lsa DNK dagi jami H bog‘lar sonini topingarrow_forward
- One of the ways for a cell to generate ATP is through the oxidative phosphorylation. In oxidative phosphorylation 3 ATP are produced from every one NADH molecule. In respiration, every glucose molecule produces 10 NADH molecules. If a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?arrow_forwardIf a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?arrow_forwardHow do i know which way the arrows go?arrow_forward
