<span>A method of deducing the correct species assignment of a living thing is known as dichotomous key, which is also called identification key. It works by requiring a user to choose two alternatives at each step and the choice of one alternatives give the name of the organism or direct further down in the key. However, a common error in using dichotomous key is the assumption that the correct name or identification of the organism is even included in the set of key. Therefore, this method alone is not reliable to identify specific species.</span>

A typical raindrop is much more massive than a mosquito and falling much faster than a mosquito flies. how does a mos quito surv
Svetradugi [14.3K]
Below are the questions:

A) A hovering mosquito is hit by a raindrop that is 45 times as massive and falling at 8.9m/s , a typical raindrop speed. How fast is the raindrop, with the attached mosquito, falling immediately afterward if the collision is perfectly inelastic? 

<span>B) Because a raindrop is "soft" and deformable, the collision duration is a relatively long 8.0 ms. What is the mosquito's average acceleration, in g's, during the collision? The peak acceleration is roughly twice the value you found, but the mosquito's rigid exoskeleton allows it to survive accelerations of this magnitude. In contrast, humans cannot survive an acceleration of more than about 10 g. 
</span>
Below are the answers:

a. <span>MU = (M + m)V; where M = 45 m, U = 8.9 m/s, find V = ?. V = (45/46)*8.9 = 8.7 m/s 
</span>
b. <span>F = m dV/dT = m 8.7/8E-3 = m 1.0875E+03; so G = 1.0875E+03/9.8 = 111 G's.</span>

How could tides and ocean currents move plastics around the ocean?
Ulleksa [173]

The plastic trash gets transported all through the planet with the help of ocean currents. The term Great Pacific Garbage Patch was first named by Captain Charles Moore. He found that huge intact substances like cups, bottles, boxes, bags, and fishing nets, and other millions of smaller pieces of plastic over an estimated region covering about 650000 to 16000000 square kilometers.  

The garbage patches are witnessed in the oceans of the world wherever there is gyre. The gyres refer to the enormous circulating regions of water comprising the prime surface currents of the globe, mediated by the existing winds. The plastics would have got caught up in a gyre and would have been ended up in a region, known as the garbage patch.  

The currents present in the gyre take in the floating substance from around the periphery and trap it in the center. The currents and waves dissociate the plastic components into smaller pieces, however, it never goes away, and gets transported to different regions with the help of currents.  

The ocean currents mediate and transport useful things like organic nutrients, heat energy, and marine species from one location to another of the planet. However, at the same time, they can also transport other unnecessary floating things like plastic garbage.  

The plastic, mainly the larger pieces that float on the surface are transported at a faster rate than the water present beneath it, this is because the wind that moves the current also moves the plastic. In this sense, the plastic is flowing freely all over the ocean surfaces of the globe.

Which of the following is an example of post-transcriptional control of gene expression?
konstantin123 [22]

Answer:

Option (c).

Explanation:

Transcription may be defined as the process of formation of RNA molecule from the template DNA with the help of enzymes and transcription factors. The transcription occurs in 5' to 3' direction.

Post trancriptional modification occurs in the RNA molecule that plays an important role in transcription as well as translation. The introns are removed from the RNA transcript and exons joined together is known as splicing. The alternative splicing occurs in which different protein isoforms are formed by the single exons.

Thus, the correct answer is option (c).
