Two brand new species of mammal like animals are found. Their relationship is unclear, however species 1 (found in India) has a claw in front that secretes a venom. Species 2, (found in Russia) also has a venomous structure, a venomous back claw. Since both species are apparently mammalian, and since both have independently figured out a way to produce claw-borne venom, it is safe to conclude that they are closely related species. a. True. b. False.

The conclusion is false

Explanation:

Species refers to organisms that have the largest number of features in common. However, ONLY one feature (claw-borne venom) has been proven to be common to

both mammalian-like animals.

Hence, it is not safe to conclude that both animals are closely related species. Thus, the statement is false

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.
