Answer:
well they can be both sometimes, some can survive in very hot environments, but most can be killed by heat so it is prokaryotic
Explanation:
Answer:
9:3:3:1
Explanation:
This question involves two different genes coding for height and flower color respectively. The first gene posseses allele T (dominant) and t (recessive) while the second gene possesses allele P (dominant) and p (recessive).
According to this question, two heterozygous tall and purple flowers are crossed i.e. (TtPp x TtPp). Each parent will produce the following gametes combination:
TtPp - TP, Tp, tP, tp
Using these gametes in a punnet square, the following proportion of offsprings will be produced:
T_P_ (tall, purple) = 9
T_pp (tall, white) = 3
ttP_ (short, purple) = 3
ttpp (short, white) = 1
Hence, the ratio of this cross is 9:3:3:1
Answer:
25%
Explanation:
From the description;
The parents: half shaded circle and square = heterozygous parents
The offspring:
unshaded square = homozygous normal
half shaded circle = heterozygous normal
half shaded circle = heterozygous normal
completely shaded square = affected (homozygous abnormal)
The unshaded and half shaded offspring are normal and do not have sickle cell anemia. The completely shaded square represents a male offspring with sickle cell anemia.
<em>Out of 4 offspring, 1 is affected for sickle cell anemia. Hence the percentage of the offspring that have sickle cell anemia is 25%.</em>
Answer:
The algae can release harmful chemicals known as "bio-toxins" that can contaminate the water and kill the organisms living in the ecosystem
