Select one:

A. Plants store genetic information in the nucleus of their cells

B. Plants are motile primary consumers

C. Plants are multicelular

D. Plants are autotrophic

Answers

Answer:

D. Plants are autotrophic

Explanation:

Both plants and animals are eukaryotic, meaning they contain a nucleus with genetic information, so that crosses out A. I don't know what motile primary consumers are. Assuming, they're primary consumers, primary consumers are those that eat producers, so in this case, this would elminate B. Both plants and animals are multicellular. Plants ARE autotrophic, meaning they produce their own food. Animals, however, have to get their own food, either by hunting or scavaging.

Determine which are true of prokaryotic and eukaryotic transcription. In prokaryotic cells _____________; in eukaryotic cells ______________.

Answers

Answer:

This question is not complete as it lacks options. However, it can be answered by giving the general differences between eukaryotic and prokaryotic transcription.

Explanation:

Eukaryotes are organisms that possess a membrane-bound nucleus that harbors their genetic material while prokaryotes are organisms that lack a membrane-bound nucleus.

Transcription is the process whereby a DNA template is used to produce an mRNA molecule. Below are the common differences in the transcription of eukaryotic and prokaryotic:

- Transcription in eukaryoric cell occurs in a NUCLEUS while transcription in prokaryotic cell takes place in a CYTOPLASM

- Transcription in eukaryotic cell requires proteins called TRANSCRIPTION FACTORS while transcription in prokaryotic cell does not require TRANSCRIPTION FACTORS.

- Transcription in eukaryotic cells occurs differently from translation while transcription in prokaryotic cells is coupled with translation i.e occur simultaneously.

If a 100-pound person played tug of war with a 50-pound dog , how light difference forces affect the results?

Answers

Answer: APPARENTLY YOU CAN battle a lion at the San Antonio Zoo. OK, it's not that kind of battle—it's a tug of war battle. There is a thick rope passing through a hole. On one end, there is a lion cub. On the other end of the rope there could be three professional WWE wrestlers. Who wins? Well, the wrestlers don't win. But there is also some physics here.

It's all about friction

A typical tug of war isn't really about strength—it's about friction. It doesn't matter how strong you are if you don't have enough friction to keep yourself from sliding. Let me show you. Here is a force diagram for two people in a tug of war.

Each puller (person pulling on the rope) has essentially four forces acting on them. There is the downward weight which is balanced by the upward push of the ground. Since the person pulls on the rope, the rope pulls on the person in the opposite direction (this because of the two-ended nature of forces). Finally, there is the frictional force between the person and the ground. If no one is "winning," all these forces add up to zero and the person stays at rest. In order to start moving in the winning direction, the frictional force must be greater than the force from the rope.

ADVERTISEMENT

This "two-ended" nature of forces means that forces come in pairs and are an interaction between two objects. It doesn't matter how hard the person on the left pulls on the rope, this same rope pulls on that person. So if you were to increase your pull to 1,000 Newtons—that same rope pulls on both people. So the key is the other force acting in the horizontal direction: friction.

The maximum frictional force depends on two things. It depends on the types of surfaces interacting (maybe it's the rubber on a shoe interacting with a concrete floor) where some surfaces just have more friction than others. You really can't change this part in a tug of war. The friction force also depends on the normal force. The normal force is the force with which the two surfaces are pushed together. In the case of this simple tug of war above, the ground pushes up with a force equal to the gravitational weight of the person. This means that heavier people will have a greater frictional force acting to help win a tug of war.

Oh, note that in the human vs. lion tug of war the humans are on a different surface than the lion. Who has the advantage? It's probably the lion since she could have uneven ground that would allow her to use more than just plain old sliding friction.

So, it's really about mass

If you have two contestants on equal ground with similar friction materials, mass matters. If the person on the left has half the mass of the person on the right, they will have half the friction. This means that it's pretty tough to beat a heavier puller.

What about the lion? This looks like a young lion—she could have a mass of about 120 kg (up to maybe 182 kg). A typical massive human wrestler might have a mass of around 90 to 100 kg. Three humans will probably have more mass than a single female lion. Probably. The humans should have an advantage in the mass.

It's also about rope friction

Wait! This isn't a normal tug of war. The rope isn't straight. Did you notice that? This can make a big difference in that it can add another frictional force into play. Let me show you how this works with a diagram of the rope as seen from the top where it passes through the glass.

What traits would help a predator be more “fit” to survive in each environment?
The environments it means are a white snowy place and a darker summer place. No links

Answers

white snowy place- color of the animals fur. For example white to blend in with the snow

A predator would likely be more fit if he could blend in with his surroundings, made minimal noise, had good hearing, and could move quickly.

What will make a predator fit in every environment?

Not simply color, but also possibly rough skin, sharp teeth, or claws to ward off predators, could have an impact on an individual's ability to survive.Microevolution (change in allele frequencies) can result via natural selection, with fitness-increasing alleles becoming more prevalent in the population.Reproductive success is measured by physical fitness (how many offspring an organism leaves in the next generation, relative to others in the group).It is the only method of evolution that may continuously lead to populations being more acclimated to, or better suited for, their environments, throughout time.

Therefore, natural selection is the phenomenon for survival of the fittest.

Some organisms have a large geographic range. For example, the Norway rat lives on every continent except Antarctica A population of Norway rats is the number of rats in one particular area. Do you think it's scientifically possible for a population of Norway rats in North America to carry different genetic mutations than a population of Norway rats in Africa? Do you think it's possible that they carry some of the same mutations? What types of information can scientists learn by studying the genomes of these two populations of rats?​

Answers

It certainly is possible that the North American population has to carry different mutations than a population of Norway rats in Africa. Genetic mutation is a random event, and the alleles resulting from mutation may rise in frequency and be fixed within the population if they provide a benefit to the fitness of the individuals with that allele. One random mutation could occur in the North American population and not be found in the African population because the occurrence of this mutation is random. It is also possible that the two populations carry the same mutations. This would be the case if the mutation occurred either if the mutation occurred in a common ancestor, or if the mutation occurred prior to the 2 populations becoming allopatric. By studying the genomes of each population scientists will be able to determine when certain mutations occurred. Mutations found in one population and not the other occurred more recently, while mutations found in both populations occurred further back in evolutionary time, and may have originated in a common ancestor.

From the California condor to the snowy owl, few birds compare to the tigers of the air: the great hunters whose beauty and skill have inspired art and literature for centuries. The most glorious feathers of the peacock or the vibrant plumage of a bunting cannot compete with the power of a peregrine falcon or the determination of an osprey. Included in this group of hunters, however, is one bird of prey that is little known but equally impressive. The kites of the world are generally smaller than most raptors, but just as astonishing in skill and grace as any other hunter of the skies.Most people think of paper or cloth structures flown with string from the ground when the word 'kite' is used. In addition to these popular toys, kite can also refer to a type of raptor. Kites have a small head, a short beak and long narrow wings and tail. Kites can be found all over the world in mostly warm regions. Kites live on a variety of preyfrom insects to small rodents or reptiles. Some kites eat only one kind of prey. Kites are generally masterful in the air and represent a group of birds that are among the most acrobatic of fliers.Two of the most familiar kites in the Southern United States are the swallow-tailed kite and the Mississippi kite. The Mississippi kite is rather plain to look at: a light brown and gray body with a buff or white colored head. But to watch a Mississippi kite fly is to watch a ballet in the air. These raptors eat primarily flying insects, so they do most of their hunting on the wing. As you might imagine, catching flying insects requires a great deal of agility and speed. If you are lucky enough to see one in flight, you will be amazed at the quick turns, graceful moves, and speedy pursuits of this bird. Look for them above large fields, especially during the summer.The swallow-tailed kite, also common in the South, is more easily identifiable and often seen flying over roads. With black wings and tail, white head and body, and a forked or swallow-like tail, this raptor is just as acrobatic as the Mississippi kite. Swallow-tailed kites like flying over highways in the summer as they can take advantage of the thermals, or columns of warmed air, that rise above the pavement. Once they have climbed to sufficient height, swallow-tails will glide, looking for snakes and reptiles and insects. They also eat small rodents, frogs, and other birds on occasion. Watching a swallow-tail fly is a lot like watching a gymnast perform a floor routine. Rarely flapping its wings, it uses its forked tail to make sharp turns, trace circles in the sky, or simply maintain a heading. Skilled, accomplished, and graceful, this bird is as entertaining as it is beautiful.Both kites are known to eat while flying, unlike most other birds of prey. This practice conserves energy and allows them to hunt almost continuously. While these kites are not listed as endangered, they are rare and in some states are listed as critical. Loss of habitat is the main reason for the decline. If you are lucky enough to see one, count yourself among the few.
