A) All cells pass the G1 checkpoint and enter into the next phase.
B) The cell can enter the G0 (resting stage) until conditions can improve.

Explain how parasitism differs from commensalism.
babymother [125]
<span>Commensalism is an interaction in which one of those species would benefit, and the other one would not be affected. Parasitism is an interaction in which one of those species would benefit at the expense of the host organism. Thus, in commensalism we have one positive and one neutral result while in parasitism we have one positive and one negative result.</span>

Given the following cross TtYyRr x TtyyRr (T = tall; t = short Y = yellow; y = green R = round; r = wrinkled), what proportion o
mihalych1998 [28]

Answer:

3/32 ttyyR-  

Explanation:

Cross: Tall, Yellow, Rounded individuals with a tall, green, rounded individual

Parentals) TtYyRr      x      TtyyRr      

Gametes) TYR, TyR, TYr, Tyr, tYR, tyR, tYr, tyr (Parent one)

                 TyR, TyR, Tyr, Tyr, tyR, tyR, tyr, tyr (Parent two)

We need to know what proportion of offspring is expected to be short plants with round, green seeds. So we need to identify the gametes for these traits. The genotypes are:

  • Shot → tt
  • Round → RR or Rr
  • Green → yy

⇒ Parent one can provide gametes tyR and tyr

⇒ Parent two can provide gametes tyR and tyr

(1/8 tyR x 2/8 tyR) + (1/8 tyR x 2/8 tyr) + (1/8 tyr x 2/8 tyR) =

2/64 ttyyRR + 2/64 ttyyRr + 2/64 ttyyRr =

1/32 ttyyRR + 2/32 ttyyRr =

3/32 ttyyR-

Compare and contrast the characteristics of the ideal tissue forming the outer surface of the body with that forming the lining
julsineya [31]

The tissue that forms the outer surface of the body is a stratified squamous keratinized epithelium. The surface layer of dead cells(stratum corneum) is made to keep things out of the body, protecting it. The tissue that lines the digestive tract(e.g. intestine). Is made from 1 layer of columnar cells that facilitate the absorption of nutrients. Both tissues are epithelia.
