Answer:
b. False
Explanation:
A scientific theory must have strong support from testable facts that are confirmed (or rejected) by observational and/or experimental procedures. The scientific method is a rigorous process that consists of arising a conjecture (hypothesis) which can be subsequently used to make predictions from its logical consequences, and finally to obtain information from empirical observations/experiments in order to obtain a conclusion about the veracity of the scientific claims (i.e., a hypothesis must be testable). In consequence, a scientific theory can not be based only on 'light' conjectures, but trustworthy observational data from the real world.
Answer:
D.
Explanation:
Sufficient inheritable variations
Answer:
Germplasm are living genetic resources such as seeds or tissues that are maintained for the purpose of animal and plant breeding, preservation, and other research uses.
Explanation:
Germplasm contains the information for a species' genetic makeup, a valuable natural resource of plant diversity. Agriculture benefits from uniformity among crop plants within a variety, which ensures consistent yields and make management easier.
Hind limbs are sturdier, longer and stronger.
The hind limbs are more firmly attached to the spine (via pelvis) than are the forelimbs
Answer:
A) reduced synthesis of ovarian steroids despite high levels of gonadotropin hormones.
Explanation:
Menopause is characterized by depletion of ovarian follicles, a reduction of ovarian hormones to castrate levels and elevated levels of serum gonadotropins. Rather than degenerating, the reproductive neuroendocrine axis in postmenopausal women is intact and responds robustly to the removal of ovarian hormones.
Menopause marks the cessation in reproductive cycles of middle-aged women. It is heralded by depletion of ovarian follicles leading to the loss of ovarian hormones with repercussions throughout the body.
