The plecostomus is popular among aquarium owners
for its ability to remove algae. It uses its strong jaw
muscles to suck food off rocks and other surfaces, like
the glass of a fish tank. The swim bladder allows the
plecostomus to stay easily wherever there is food,
often near the bottom of the tank. The plecostomus has
large scales and a hard skeleton.
To which group of fish does the plecostomus belong?

A disaster wipes out 50 percent of a small population of birds. Prior to the disaster, about half the birds had a green wing patch and half had a blue wing patch. Several generations after the disaster, only 10 percent have a blue wing patch, and 90 percent have a green wing patch. What do you infer happened, and why?
Answer:
The correct answer is - genetic drift takes place due to disaster in favor of a green wing patch.
Explanation:
In this given scenario there is disaster happened that wiped out 50% of a population of birds in which half had green wings and the rest half had blue wing birds before the catastrophe.
Due to this sudden catastrophe, the genetic drift occurred and also reduced the population to half and the ratio of both types of birds changed and favored the green wings as they are better adapted for the new conditions.

Explain how errors in DNA replication and environmental factors cause genétic variation
DNA replication is a truly amazing biological phenomenon. Consider the countless number of times that your cells divide to make you who you are—not just during development, but even now, as a fully mature adult. Then consider that every time a human cell divides and its DNA replicates, it has to copy and transmit the same sequence of 3 billion nucleotides to its daughter cells. Finally, consider the fact that in life (literally), nothing is perfect. While most DNA replicates with fairly high fidelity, mistakes do happen, with polymerase enzymes sometimes inserting the wrong nucleotide or too many or too few nucleotides into a sequence. Fortunately, most of these mistakes are fixed through various DNA repair processes. Repair enzymes recognize structural imperfections between improperly paired nucleotides, cutting out the wrong ones and putting the right ones in their place. But some replication errors make it past these mechanisms, thus becoming permanent mutations. These altered nucleotide sequences can then be passed down from one cellular generation to the next, and if they occur in cells that give rise to gametes, they can even be transmitted to subsequent organismal generations. Moreover, when the genes for the DNA repair enzymes themselves become mutated, mistakes begin accumulating at a much higher rate. In eukaryotes, such mutations can lead to cancer.
What do all members of the swine species always have in common? They always have the same number and kinds of chromosomes. They are always preyed upon by the same predators. They always occupy the same habitat at the same time. They always occupy the same position in the food web no matter where they live.
Answer:
Members of the swine species always have the same number and kinds of chromosomes
Explanation:
The swine species always have their food habits in common. They are omnivorous and they also due to ancestry have the typical type of genes and chromosomes inscribed in it. Hence swine are used in research industry nowadays like dogs and monkeys.
Wild boars, hogs and pigs all have just small differences externally. Their anatomy and physiology are identical. They are all mammals. They are highly intelligent and talented ones. They have their physiology identical to ours which helps in research scientist to experiment and finds cure for human.
Answer:
biological definition of species, which works for sexually reproducing organisms, is a group of actual or potential interbreeding individuals. There are exceptions to this rule. Many species are similar enough that hybrid offspring are possible and may often occur in nature, but for the majority of species this rule generally holds. The presence in nature of hybrids between similar species suggests that they may have descended from a single interbreeding species, and the speciation process may not yet be completed.
Given the extraordinary diversity of life on the planet there must be mechanisms for speciation: the formation of two species from one original species. Darwin envisioned this process as a branching event and diagrammed the process in the only illustration found in On the Origin of Species (Figure 1a). Compare this illustration to the diagram of elephant evolution (Figure 1b), which shows that as one species changes over time, it branches to form more than one new species, repeatedly, as long as the population survives or until the organism becomes extinct.
Explanation:
For speciation to occur, two new populations must be formed from one original population and they must evolve in such a way that it becomes impossible for individuals from the two new populations to interbreed. Biologists have proposed mechanisms by which this could occur that fall into two broad categories. Allopatric speciation (allo– = “other”; –patric = “homeland”) involves geographic separation of populations from a parent species and subsequent evolution. Sympatric speciation (sym– = “same”; –patric = “homeland”) involves speciation occurring within a parent species remaining in one location.
Biologists think of speciation events as the splitting of one ancestral species into two descendant species. There is no reason why more than two species might not form at one time except that it is less likely and we can conceptualize multiple events as single splits occurring close in time.
Allopatric Speciation
A geographically continuous population has a gene pool that is relatively homogeneous. Gene flow, the movement of alleles across a species’ range, is relatively free because individuals can move and then mate with individuals in their new location. Thus, an allele’s frequency at one end of a distribution will be similar to the allele’s frequency at the other end. When populations become geographically discontinuous, it prevents alleles’ free-flow. When that separation lasts for a period of time, the two populations are able to evolve along different trajectories. Thus, their allele frequencies at numerous genetic loci gradually become increasingly different as new alleles independently arise by mutation in each population. Typically, environmental conditions, such as climate, resources, predators, and competitors for the two populations will differ causing natural selection to favor divergent adaptations in each group.
What wave lengths of light do each of the pigments reflect?
Answer:
All photosynthetic organisms have chlorophyll which absorbs violet–blue and reddish orange–red wave lengths chlorophyll reflects a green and yellow–green wavelengths accessory photosynthetic pigments by including chlorophyll beta–caeotene that absorbs energy therefore then the chlorophyll does not absorbs. Most pigments work by absorbing certain wavelengths of lights the other wavelengths are reflected or scattered that which causes you to see those colours the nergy of the light is absorbed to excite the electrons so it no longer able to seen by your eyes

Ciliates and fungi diverged more recently than ciliates and flagellates and Ciliates are more closely related to animals than they are to flagellates shows hypothetical model of the relationships between groups of organisms.
What is hypothetical model?Hypothetical modeling involves the design and analysis of basic hypothetical systems to represent complicated social phenomena for the purpose of understanding those social phenomena.
Hypothetical modeling is contrasted with both computer simulation and lab experiments to emphasize its key characteristics.
In analogy with laboratory experiments, hypothetical models can be viewed of as scientific representations that aim to isolate, hypothetically, the working of causal mechanisms or capacities from disrupting influences.

Explanation:
its simpler then it looks☺
Baby with blood group O belongs to Mr. and Mrs. Jones, baby with blood group B belongs to Mr. and Mrs. Williams, and baby with blood group AB belongs to Mr. and Mrs. Wilson.
What is a blood group?
Blood group or blood type is the classification of the blood cells into different classes on the basis of presence or absence of antibodies and antigens on the membrane of the blood cells.
The alleles which can be formed in case of Mr. and Mrs. Jones are AA or Ai type. These alleles can only result into formation of an offspring with blood group O or A. Similarly, the possible combination of alleles in case of Mr. and Mrs. Williams is AB and ii, these combinations will result into development of offspring with blood group A or B. In case of Mr. and Mrs. Wilson, the possible combinations of alleles are Ai or AA and Bi or BB, which results into formation of offspring with blood group AB.
