An American cockroach (Periplaneta americana) can begin to turn away from approaching danger, such as a hungry toad lunging towa

rd it or a flyswatter wielded by a cockroach-loathing human, in as little as a hundredth of a second after the air pushed in front of the moving object reaches the roach’s body. A cockroach has very sensitive wind sensors on its cerci, which are small appendages at the end of its abdomen. One cercus points slightly to the right, the other to the left. Use what you know about moth orientation to bat cries to suggest how this simple system might provide the information the roach needs to turn away from an attacking toad, rather than toward it. How might you test your hypothesis experimentally?

Answer:

The roaches antennas

Explanation:

the roaches antennas sense movement from far so the antennas sense when the roach is in danger their for it moves away not towards it.

Let’s assume that dragons show incomplete dominance for fire breathing. The F allele provides lots of fire and the F’ allele giv
laila [671]

The progenies of the dragons with strong fire and dragon with no fire will be dragons with fire at medium rate.

<h3><u>Explanation:</u></h3>

Incomplete dominance is the phenomenon when two different alleles are present in a same organism gives a mixed type of phenotype which isn't similar to any characters of the parents.

In case of the dragons, the genotype of the dragons with strong fire = FF.

The genotype of the dragons with no fire = F'F'.

So the gametes produced by the dragon with strong fire is F and that by the dragons with no fire is F'.

So the dragons produced as a progeny = FF'.

As this gene shows incomplete dominance, so both the characters will be mixed and present as a mixed character. So the offsprings will be moderately fire breathing.

Which type of water balance disorder would be caused by renal failure?
Vladimir79 [104]

Answer: <em>C. Volume Excess</em>

Explanation:

Patients with impaired kidney function or renal failure, usually suffer from an excess volume of water in their bodies, because the urinary output they have is decreased and in some cases absent. Water excess starts accumulating on the circulatory system, and then it diffuses into the soft tissues of the body.

They also suffer from electrolytic disorders.

There are 150 Pakicetus in the population at present. Assume Charles had another mutation; this one at the B locus, to produce a
alekssr [168]

Answer: Hello your question is incomplete below is the complete question

Let’s look at a different gene locus, we’ll call it B. The normal, wild type, the population was 100% BB. There are 150 Pakicetus in the population at present. Assume Charles had another mutation; this one at the B locus, to produce allele b. What is the gene frequency of allele b in the population if the population of Pakicetus reaches 100,000

answer : ≈ 1

Explanation:

<u>Determine the Gene frequency of allele b </u>

Population = 100,000

There are 150 Pakicetus in population i.e. 300 alleles at locus B

hence the frequency of b = 1/300 = 0.33%

Increase in population does not affect frequency of b ( HW equilibrium )

<em>therefore the Gene frequency of allele b </em>

= 0.33% * 0.33% * 100000 = 1.08  

≈ 1
