Sperm tails in the fruit fly Drosophila bifurca can reach up to 6cm long, which is over 20 times the length of the organism itse

lf. Because the tails are so long, they aren’t able to provide the swimming force that other sperm tails are used for. Please provide a hypothesis as to why the fruit fly sperm has evolved to be so long.?

Explanation:

The length of the sperm in a few species is much larger or giant than the size of the animal-like observed in the <em>Drosophila bifurca. </em>

In this fruit-fly, the tails of the sperm are too long which could be accounted for many reasons:

1. The sexual selection prefers the long tails over the small tail.

2. The large sperms can displace the small sperms in the female reproductive organ.

3. The female reproductive organ increases the promiscuity of the large sperms that is favour the large sperms over the small sperms.

How does predation alter a population’s gene pool?
Phoenix [80]

Answer:

Option C

Explanation:

If we consider Darwin's theory we would realize that the species which are not able to survive are unfit or weak. Thus, predators usually attack species that can be easily targeted. Hence, it this way predation leads to selective pressure on any species and hence leads to creation of a fit gene pool. The weak organisms are removed and more fit organism could mate among themselves to produce healthy offspring.  

 Hence, option C is correct

What is the predominant mode of asexual reproduction in a sponge?

Budding  is  the  predominant  mode  of   asexual  reproduction  in  sponge. Budding  is  a  asexual reproduction  in  which  a  new  organism   develop  from  outgrowth or   from  bud   due  to  cell  division   at   one  particular  site. A  small  rounded  outgrowth  on  asexually  reproducing  organism  is  cabable  of  developing  into  new individual

These are fossils of a fish (vagrant pelagic vertebrate; sample a), and a coral (sessile benthic cnidarian; sample b). in genera
densk [106]
The coral fossil would be a better estimate of past water depth. This is because most corals inhabit shallow water reefs, less than 150 feet deep. In contrast, pelagic fish may inhabit any open water (pelagic) part of the ocean, with depths ranging anywhere from a couple of hundred feet deep to miles in depth.
