The correct answers are:
Trematodes are acoelomates that have effective defenses against attack by their hosts' immune system.
Trematodes are flatworms, internal parasites known as flukes. Their life cycle is complex: they sexually reproduce in vertebrates and asexual reproduce in mollusks (mostly snail). The body of flukes is covered with tough tegument that defends them form digestive enzymes of host’s intestine.
Cnidarians are diploblasts that produce complex, capsule-like organelles.
Cnidaria are water organisms with simple structure: two layers of epithelium and a jelly substance between them. The cells of Cnidaria-cnidocytes contain capsule with venom substance in it with protective role.
Answer: 1. B-D-A-C.
Explanation: If a genetic error occurs during chromosome replication, it will lead to a series of events ranging from:
1) Production of a DNA strand with an altered base sequence.
2) Production of an mRNA strand with an altered base sequence during transcription. This is because mRNA is synthesized by copying the genetic message coded in the DNA.
3). Synthesis of a protein with an altered amino acid sequence during translation, and this eventually leads to
4). The expression of a new inheritable trait in the organism.
<span>Genetic variation in bacterial made it possible for some individuals to have resistance to the antibiotic, survive, and reproduce is a statement that explains the theory of evolution very well. Some of the bacteria that became resistant to the antibiotics, passes this down the genes for drug resistance. I hope the answer helps you.</span>
The diploid phase of the life cycle begins with the formation of the zygote.
Meiosis is referred to the type of cell division which occurs in the production
of male and female sex cells. This also occurs during sexual reproduction.
Parent cells provide male and sex cells such as sperm and egg which
contains DNA. They then fuse together to form a zygote which is the diploid
phase as a result of the fusion of two haploid cells. The zygote then
continues to undergo some meiotic processes which reduces it to back to a
haploid cell and consequent growth to form a fetus.

Answer: 2.81 x 10∧14 baterias after 16 hours.
Explanation:
Hi, first we have to find how many 20 minute intervals are in 16 hours.
If 1 hour = 60 min, 16hours = 960 minutes (16 h x 60 min / 1 h)
If we divide the 960 minutes (16 hours) by 20 minutes we obtain 48. (960/48)
There are 48 twenty minutes intervals in 16 hours.
Now we have to apply the exponential growth formula:
P (t) = Po (1 +r) ∧t
Where:
P (t) = population at time t
P (0) = initial population (1)
r = growth rate (1)
t = time (48)
Replacing with the values given:
P (t) = 1 (1 + 1) ∧48= 2.81 x 10∧14
2.81 x 10∧14 baterias after 16 hours.
