Can someone pls help me on this?

i don't know what the picture looks like but i can take a guess and say maybe basidiomycetes?

helicase, i think thats it

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.

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.
