if the southern latitudes get more sun exposure for longer hours per day than Northern latitudes predict the effects on the animals living in the two locations​

Answers

Answer:

Date and latitude interact to determine photoperiod, the daily period of daylight. This interaction has important implications for latitudinal migrants for whom daylight may be a resource or for whom photoperiod regulates annual transitions in life‐history stages (i.e. birds).

Using an established formula, we developed user‐interactive, animated models that enable the visualization of how latitude and date determine photoperiod for latitudinal migrants. We also calculated the photoperiodic schedules for a broad range of hypothetical migratory programmes and real migratory programmes newly available through the proliferation of citizen‐science data. This enabled us to infer the limitations some migratory programmes place on mechanisms for photoperiodic regulation of annual breeding.

In the vast majority of cases, the act of migrating elevates annual daylight exposure. This raises the hypothesis that daylight availability selects for latitudinal migration, potentially contributing to its evolution in animals such as diurnal birds with limited time during the spring and summer to feed young. However, photoperiodic mechanisms regulating annual cycles could constrain the evolution of such migrations, depending on how they affect photoperiodic schedules. Most migratory programmes are consistent with known mechanisms of avian photoperiodism, but the range of feasible mechanisms declines for transequatorial migrants, which experience semi‐annual, 180°‐phase‐shifts in their photoperiodic cycles.

Understanding photoperiodic constraints on migration are particularly important in this age of changing latitudinal distributions and phenologies driven by climate change.

What is it called when certain species have evolved such intimate symbiotic
relationships that individuals of either species cannot survive without one another?

a. obligate

b. parasitic

c. mutualistic

d. facultative

Answers

Answer:

A. Obligate

Explanation:

An obligate relationship is one where both organisms are interdependent with one another in a way that one cannot survive without the other.

A parasitic relationship is where one organism benefits, and the other is harmed.

A mutualistic relationship is one where both organisms "work together," therefore benefiting one another.

A facultative relationship is where both species benefit off of one another, but are not fully dependent on one another to the point they cannot survive without their symbotic partner.

Answer:

quantitative data

"quantitative" refers to the amount of something, so if it has something to do with numbers, It's quantitative.

There were twelve elephants in the clearing, which is quantitative data, while the pulse rate of 141 beats per minute is also quantitative data, but the orange fur with black stripes is qualitative data.

What quantitative and qualitative data are there?

There are both types of data, such as the quantitative data, in which the quantity can be measured, such as the 12 elephants and the 141 beats, and the qualitative data, which can't be measured but is widely seen in the genetics, such as the coat color of the animals, the skin color of the human, etc.

Hence, there were twelve elephants in the clearing, which is quantitative data, while the pulse rate of 141 beats per minute is also quantitative data, but the orange fur with black stripes is qualitative data.

As carbon moves throughout earths systems how are different parts of the biosphere(the part occupied by living things) affected?

Answers

Answer:

Carbon is an essential factor to the survival of living things.

Explanation:

It is produced as a waste by-product of metabolism in living organisms and combines with oxygen to be released as Carbon Dioxide (CO2).

Plants on the other hand require CO2 to process sunlight and nutrients into energy. They in return release oxygen which is required by animals to break down food.

Factories, businesses, people (as they generate electricity, transport people and goods, etc) release lots of carbon into the atmosphere it also combines with oxygen again to form C02.

The ocean and water bodies also serve as a collecting conduit of CO2, especially where the water temperature is relatively warm. When CO2 is captured by the ocean, it is used by some sea animals to make shells.

a student wants to hold the sides of a garbage bag to the sides of her trash can she tries round rectangular and square shaped magnets but the magnets do not stick to the sides of the trash can, what is a reason the magnets do not stick to the sides of the trash can ?

Answers

Answer:

If the insulating material covered around the can.

Explanation:

If the can is covered with thick layer of insulating material then it can't be attracted by the magnet because there is a gap between magnet and metal. Can is a metal which is attracted by the magnets just like iron and copper etc. If there is no insulating material between magnet and can, then it must be attracted by the magnet so that's why we can say that insulating material is responsible for the no attachment of magnet to the can.

Thomas Malthus was an economist who influenced Darwin's developing theory of evolution. Malthus observed that the birthrate among humans exceeded the death rate. If this trend continued, soon there would not be enough resources to support human population growth. He reasoned that the only things capable of stopping human population growth were famine, disease, and war. Darwin applied this thinking to animals and plants as well, noting that far more offspring were produced than survived to a reproductive age. 2. How did Charles Darwin build on the work of Thomas Malthus to develop the idea of evolution by natural selection

Answers

Answer:

The work of Thomas Malthus help and influence Darwin Thomas to refine his theory of natural selection by explaining that there is a meaningful competition between the individuals of a particular species or population for a specific resource such as food or shelter.

Thomas Malthus predicted that the human population is reproducing faster than its death race and will lead to growing faster than space and food supplies needed to sustain it. Darwin concluded further that If all offspring of almost any species survived for several generations, they would overrun the world and therefore a healthy and meaningful competition is present and to overcome this natural selection takes place as the individual adapt will ultimately survive.

B
What is the frequency of the wave?

C
What is the wavelength of the wave?

D
What is the wave speed in a vacuum?

Answers

Answer:

It would be B

Explanation:

I am sorry if it is wrong

"What is the frequency of wave?" is not a question that she can ask. Thus, the correct option is B.

What is the frequency of wave?

Wave frequency is the number of waves which pass through a fixed point in a given amount of time. The SI unit for wave frequency is the hertz (Hz). One hertz (Hz) equals 1 wave passing a fixed point in the time period of 1 second. A higher-frequency wave has more energy than a lower-frequency wave with the same magnitude of amplitude.

The equation used for determination of wave frequency (f) will be:

f = v/λ

where λ is the wavelength in meters and v is the speed of the wave in m/s.

Therefore, the correct option is B.

16. The substances that are reabsorbed did not diffuse (move) from the nephron bowl into the

process do you think the kidney uses to transport these substances from the nephron to the
renal vein-active transport or diffusion (passive transport)? Explain your answer.

Answers

Answer:

Active transport.

Explanation:

The kidney uses active transport  to move these substances from the nephron to the  renal vein because these substances did not moves from the nephron bowl to the renal vein through simple diffusion so for this purpose active transport is used in which energy is spent in order to move the substances from one region to another so we can say that kidney must use active transport to move reabsorbed substances from the nephron to the  renal vein.

Heron was large and slow, with a long, gangly neck and big, floppy wings. Hummingbird was tiny and swift, with wings that moved so quickly that they buzzed and a slender beak as sleek as a needle.Heron and Hummingbird both loved to eat fish from the river. Every morning, Heron would fish to her heart's content, eating until her stomach was so round and heavy that she had to waddle back to shore. Every afternoon, Hummingbird would fish and feast until he was so heavy that his tiny, buzzing wings could no longer keep him in the air. Heron and Hummingbird thought they were the luckiest birds in the world.One afternoon, Hummingbird did not catch as many fish as usual. He fished and he fished, but his line came up empty more times than it ever had before. He flew to Heron's house."Heron! Heron!" he called. "Why have you eaten all the fish?"Heron bustled to her door, angry and surprised at her friend's accusation."Me? Eat all the fish?" she squawked. "I barely caught anything this morning! My poor stomach has been growling all day."The two birds began to argue over who had eaten more fish. Finally, Hummingbird raised his wing to stop the debate."I do not think there are enough fish left in the river for both of us," he said. "Let's have a race. Whoever reaches the dead tree on the other side of the hills first owns all the fish. The loser has to find something else to eat."Heron agreed. They prepared to race. Hummingbird was certain that he would win. He watched Heron as she awkwardly stretched her wings and prepared to fly. This will be like catching fish in a barrel, he thought with a grin.Hummingbird zoomed past Heron as soon as the race began. He flew so far ahead that he lost sight of her behind him. He slowed down as he passed a patch of wildflowers. They smelled so sweet that he had to stop and look at them more closely. Hummingbird just had to try some of their nectar. He drank until his belly was heavy and his eyelids drooped. Perhaps just a short nap, he thought, as he settled himself into a nest of soft leaves.It was late in the day when Hummingbird woke up. He stretched his wings and glanced at the sky. He could just make out the shape of Heron, flying slowly but surely toward the dead tree. She was almost done with the race! Hummingbird zipped into the air and flew as fast as he could, but it was too late. Heron reached the tree first. From that day forward, Heron owned the fish, and Hummingbird lived on nectar.Select the sentence from the story that supports the inference that Hummingbird feels confident about racing Heron.A.
