28) Yeast cells reproduce quickly by budding. This is a form of( asexaul ) reproduction so all the yeast cells (). < should you write a word or a sentence here ? 
anyway let me explain the answer to you ... why its asexaul reproduction ? because it doesn't involve 2 parents one parent is needed only , its  without gametes ( sex cells) , pollination , fertilisation and dispersal . 
We know if this is an asexaul reproduction if it :-involves one parent .- the characteristics of the  offspring is identical to the parent . - the offspring is identical to the parent genetically .- the reproduction rate is rapid because of the favourable conditions . 

thats it , hope you got the point . 
Pray for me . best of luck 

Stress causes an increased production of a steroid hormone known as cortisol. It functions to increase blood sugar, to suppress the immune system, and to aid in the metabolism of fat, protein, and carbohydrates. It also decreases bone formation.
