The lining of the mouth and anus originate from the mesoderm. The correct order

Question

The lining of the mouth and anus originate from the mesoderm. The correct order of several developmental processes is as follows: cleavage rightarrow gastrulation rightarrow organogenesis/neurulation. Similar fusiform body shapes are seen in sharks, penguins, and aquatic mammals (seals and sea lions) because the laws of physics constrain the shapes that are possible for aquatic animals that swim very fast. The female reproductive tract is protected by acidic mucus and WBC's; both of these factors make it more difficult for the sperm to fertilize the egg. Fertilization occurs in the oviduct; if implantation occurs there instead of in the uterus, it becomes a dangerous ectopic pregnancy. High density lipoproteins (HDL's) damage the arterial lining of coronary arteries, causing a heart attack or myocardial infarction. In the idealized 28-day human-female menstrual cycle, the endometrial lining is most highly developed at about day 14-15, corresponding to ovulation TRUE OR FALSE?

Explanation / Answer

ANSWER 39) FALSE because the origination is ectodermal.

answer 40 ) TRUE firstly the cleavage occurs and than the formation of gastrula and neurulation occurs.

answer 41) TRUE fusiform shapes are seen in sharks penguins and other fishes as it provides less hindrance in water and easy to swim . beacuse the pointed mouth gives more pressure to displace water.

answer43) TRUE

ANswer 44 FALSE this case will occur with low density lipoprotien.

answer45) TRUE the lining will shed when the progesterone level deceses and this will occur after ovulation
