Answer: Both the smooth and rough endoplasmic reticulum help in the production and storage of proteins The main difference is that one contains ribosomes on it and the other does not.
Explanation: The main difference lies between the SER and RER is the presence of ribosomes, as SER do not have ribosomes but RER have ribosomes.
Answer:
The correct answer will be option-E.
Explanation:
The menstruation period in females is divided into the follicular phase and the luteal phase.
The follicular phase is characterized by the folliculogenesis or the formation and maturation of the follicles to produce ovum or egg cell. The follicular phase is co-related with the ovulatory phase during the first 14 days of the cycle.
As the follicles matures, the follicle starts releasing estrogens and progesterone as the well rising level of FSH and LH. The rise in LH helps in ovulation while the rise in progesterone maintains the endometrium of uterus to ensure pregnancy.
Thus, option-E is the correct answer.
Answer:
The correct answer is option B. "Tensor veli palatini".
Explanation:
Masseter muscle plays an important role in chewing solid foods while the tensor veli palatini acts elevating the palate and preventing that food goes into the nasopharynx. A progressive degeneration of the motor axons that innervate the masseter muscle will likely produce a similar effect in the tensor veli palatini muscle. Not only both muscles have functions during chewing of food, but also both muscles are controlled by similar motor axons.
Well, considering that seagulls, bears, and cows are warm blooded mammals, and spiders are arachnids with an exoskeleton, I'm willing to bet that spiders are ectothermic. And isn't the word exothermic?
