D! They are both decomposing dead organic matter and metabolizing it through certain pathways to obtain energy! Hope this helped :)
They surround and engulf foreign objects and organisms- process called phagocytosis
His and her child is also AB cause its the blood type of his/her parents
Answer:
- 120 individuals yySs
- 60 individuals yyss
Explanation:
<u>Available data</u>:
- Two autosomal diallelic genes Y and S
- Y is the dominant allele that codes for yellow
- y is the recessive allele that expresses black
- S is the dominant allele that expresses stars
- s is the recessive allele that codes for starless
- Lethal genotypes: YYss and yySS
1st cross: A true-breeding yellow star bellied sneetch with a true-breeding black starless sneetch
Parentals) YYSS x yyss
F1) 100% YySs
N = 50
2nd Cross:
Parentals) YySs x YySs
Gametes) YS, Ys, yS, ys
YS, Ys, yS, ys
Punnett square) YS Ys yS ys
YS YYSS YYSs YySS YySs
Ys YYSs YYss YySs Yyss
yS YySS YySs yySS yySs
ys YySs Yyss yySs yyss
F1) N = 840
- 14/16 survivers
- 2/16 death YYss and yySS
- 9/16 yellow with stars
- 2/16 yellow starless Yyss
- 2/16 black with stars yySs
- 1/16 black and starless, yyss
14 ------------------ 100% of the progeny --------------840 individuals
2 yySs -----------X = 14.28% ------------------------------X = 120 individuals yySs
1 yyss ------------X = 7.14% ------------------------------X = 59.97 individuals yyss
