Flatworms have layers of tissue that surround the gut and organs in one solid body. They are _____.a. Acoelomates
b. Pseudocoelomates
c. coelomates

Answers

Answer 1

Answer:

Answer: a. acoelomates

Explanation:

Flatworms belong to the phylum Platyhelminthes. The body of these worms are flattened from top to bottom, that’s why these worms are called flatworms. They are bilaterally symmetrical and triploblastic (having three germ layers) organisms but they lack a body cavity or coelom. The body systems such as digestive, muscular, nervous, excretory, and reproductive systems are developed. Examples are flukes, tapeworms.

Answer 2

Answer: a. Acoelomates. Flatworm is a type of acoelomate animal; they have no body cavity or ceolom but they have mesenchyme in their body cavity that surrounds the gut and organs in one solid body.

A vaccine is used to kill viruses. It attacks the weak part of the virus and kills it.

Answer:It is used to eliminated viruses in your body.

Explanation:

Like a flu shot for example, it signals your immune system to generate cells to kill the influenza inside your body so it doesn't replicate inside your DNA.

The geneticists studying the alien organisms have deciphered their genetic code. For Familiarity, they have used A, C, G, and T to indicate the bases in this code. A comparable genetic sequence in each alien has been identified in the genes that code for eye growth. This genetic sequence has allowed the aliens to be divided into six groups, with the single-tail three-eye group split in half. The geneticists also studied several outgroup species (not shown) to compile a likely ancestral DNA sequence. From this information, they have constructed four possible phylogenetic trees. Based on this genetic information, which phylogenetic tree is most parsimonious? a) phylogenetic tree I
b) phylogenetic tree II
c) phylogenetic tree III
d) phylogenetic tree IV

Answers

Answer:

Your question is incomplete, but I attached the exercise with the possible phylogenetic trees and all the information that your question missed. I hope it helps you.

The most parsimoniuous phylogenetic tree is c) phylogenetic tree III

Explanation:

The most parsimonious tree is the one that takes fewer base-change events, it's the simpler one. In this case it could be tree III or tree IV. But, if we look at the genetic evidence, group 2b and 3 are nearer than 2b and 2a; group 4 and 5 are also closely related. So it is possible that the group 2b, as well as groups 3,4 and 5, diverged from group 2a. So the answer is tree III.

Final answer:

The most parsimonious phylogenetic tree is the one that requires the least changes in the A, C, G, T genetic sequence coding for eye growth, thereby presenting the simplest explanation of evolutionary relationships among the alien species.

Explanation:

The question is asking which of the four possible phylogenetic trees represents the most parsimonious, or simplest, explanation of the shared genetic sequence for eye growth among the alien species. The most parsimonious tree would be one that requires the least amount of evolutionary change in terms of the genetic sequence. This would be determined by comparing each tree and the associated genetic sequences in the way they separate the six groups of aliens and particularly how they divide the single-tail three-eye group. This should provide the simplest explanation of evolutionary relationships based on the alien's genetic code of A, C, G and T.

Two objects are 5 kg and 10 kg respectively, and they're 10 m apart. If the distance between them is increased to 20 m, what happens to the gravitational force?A. It decreases.B. It increases slightly.C. It is doubled.D. It doesn't change

Answers

Answer: OptionA it decreases

Explanation :

The formula for gravitational force F is given by

F = G M1*M2/ $d^(2)$

where, G is the gravitational constant

M1 and M2 is the mass of the two bodies.

d is the distnce between the two bodies.

Now according to the question,

M1 = 5 kg

M2= 10 kg

d = 10

If we put these values in the formula we get,

F = 6.67 * $10^(-11)$ * 5 *10 / $10^(2)$

F = 3.335 * $10^(-11)$

Now, if the d= 20

then the answer comes out to be 0.83375* $10^(-11)$

Thus, we can see that the gravitational force decreases.

We can also find the answer without any calculation from the fact that in the formula the force is inversely proportional to square of distance, thus as the distance increases, the gravitational force decreases.

i think B. It increases slightly.
