Explanation:

The zooplankton count as an animal, a plant can't eat an animal that's why the sponge count as an animal.

The correct answer is; "Assembling molecules in either hydroxyl or carboxyl functional groups"

Polymers are formed from monomers either by condensation or by addition of monomers.

A polymer is formed by the joining of one or more monomers. This can happen in either of the following ways;

Condensation polymerization involves the loss of a small molecule. When the molecule that is lost is water, we can call it dehydration. Loss of molecules does not occur in addition polymerization.

The two monomer molecules that join to yield the polymer by dehydration must have H and OH moieties in suitable positions for dehydration to occur. A typical example is assembling molecules in either hydroxyl or carboxyl functional groups.

The correct answer would be that substance A is rice, and substance B is sugar.

For substance A to be filtered out, it means that A is a water-insoluble substance and for substance B to be recoverable by evaporating off the water, it means that B is water-soluble.

Thus, A can neither be sugar nor alcohol because neither can be recovered by filtration. Also, B can neither be coffee nor alcohol because they can not be recovered as residue through evaporation of water.

Therefore, the only correct answer is that substance A is rice, and substance B is sugar because rice can be filtered out from water while the water-soluble sugar can be recovered by evaporating the water.

Answer:

1,6 m / s ^ 2

Explanation:

De las leyes de Newton;

Fuerza = masa × aceleración

masa = 275 kg

Fuerza = 440 N

Aceleración = Fuerza / masa

Aceleración = 440N / 275Kg

Aceleración = 1,6 m / s ^ 2

Um well the 42 year old man should have reserched what would happen. When pumping liquid oxygen into his grill So that way he could know more of what was happening and the consequinces

Explanation:

Although your question is incomplete a more general answer is provided.  pumping of liquid oxygen into fire will lead to Vigorous burning/explosion

Liquid oxygen is oxygen compressed and stored in the form of liquid in cylinders. liquid oxygen is made available for patients with difficult in breathing and it also used for industrial process. Liquid oxygen have a boiling point that is below -238°F.  therefore

Some of the hazards associated with liquid oxygen are

Hence The hazard associated with liquid oxygen that led to 42 year old male been rushed to the ER is due to the Vigorous burning/explosion associated with the exposure of liquid oxygen to flame.

The characterization of each biome is as follows:

A biome may be defined as a very large ecosystem that is running in nature in an unmanaged way. In a more simple sense, a biome is characterized as a very large area that is significantly characterized by a particular type of vegetation. Some examples of biomes are tropical rainforests, coral reefs, grasslands, etc.

Temperate deciduous forests have an average rainfall of 75 to 200 cm/year and a temperature of 12 degrees Celcius. Tropical rainforests feel higher rainfall and temperature ranging from 25 to 29 degrees Celcius.

Therefore, the characterization of each rainfall is well described above.

The five evidences that support the theory of evolution are: Fossils, Anatomy, Embryology, Molecular Biology (or Biochemistry), and Biogeography.

Fossils show the physical change in a species over time, suggesting evidence for evolution. For an example, we can trace the origins of dolphins and whales all the way to a four-legged, dog-like hoofed mammal from about 50 mya. These mammals were fish eaters and so decided to spend a lot of time in the water. In fact, they spent so much time in the water, that in a few million years, they evolved a longer body and webbed feet. Then another few million years passed and they swapped their webbed feet for flippers and swapped their tail of a fin. Eventually, we get a fish-like mammal that once walked on land.

For anatomy, or structures, there's three types of structure comparisons: Homologous structures, Vestigial structures, and Analogous structures (or Convergent Evolution). Homologous structures show similarities between the structures between species, but serve different purposes. For an example, all mammals share common features within their arms, such as having 5 fingers. However, they serve different purposes, from whale fins for swimming, to bat wings for flying, to human hands for grabbing and for using tools.

Vestigial structures were structures that once served a purpose and have been reduced in size/power to the point where it's useless. For an example, large theropods such as the T. Rex spent so much time evolving more jaw muscles and biting power, that they sacrificed their arm muscles for such power. This explains why their arms were so short.

Another example would be ratites, flightless birds such as ostriches, emus, and cassowaries (penguins and kakapos are from a different group). They spent so much time evolving powerful legs as well as evolving in size, that there was no need to fly when they could just run with their improved legs. And also the fact that they're too heavy to even fly anyways.

Analogous structures is the similar functions of structures between species, but have separately evolved these functions. For an example, the wings from insects, birds, bats, and pterosaurs are very similar in shape and can be used to fly, but they've evolved separately. For an example, birds use feathers to fly while bats and pterosaurs use/used (pterosaurs are extinct) membrane between their bones to fly. Although they do have strikingly similar evolutionary histories, with their ancestors starting off as tree dwellers, they've evolved their flight abilities separately during different earth periods.

Embryology is evidence for evolution by using embryos from different species to suggest a common ancestor. For an example, we can prove that we're more related to whales than to fish by using embryos. The fish embryo will evolve gills while the embryos of humans and whales will not, since we do not breath by extracting oxygen from water.

Molecular biology is a more recent way of providing evidence for evolution. By taking the DNA from cells from different species, we can get an estimate of how related one species is to another. The more similar amino acid sequences are between species, the more recent their common ancestor is. For an example, by comparing amino acid sequences between humans and chimpanzees, we get an estimated amount that we once shared a common ancestor seven million years ago. Without molecular biology, we would still be digging for fossils to find that number.

Biogeography is the geographic distribution of species on earth that can be explained by evolution. For an example, we can tell that Australia separated first from Pangea rather than Asia or North America since Australia doesn't have bears while the Asia and North America do, with China having pandas and North America having brown and black bears. And also with the fact that Australia is the only continent with monotremes (egg-laying mammals like the platypus).

Similar to biogeography, there's also direct observation, which is evolution that has happened in our own eyes. An example would be the underground London mosquito. Mosquitoes usually target birds like pigeons. But after an underground tunnel was built in London, some mosquitoes managed to get inside and instead of birds, they targeted, mice, rats, and of course, humans. After only a few hundred years, a mosquito from the underground tried to mate with another mosquito from land and they could not, simply because they were different species. This shows that their new choice of feeding on mammalian blood has actually altered their DNA and created a new species, during the existence of humanity!
