Answer:

It was difficult for him to understand how the heart worked because he wasn't fully aware of the pumping mechanism of the heart and how the circulation of blood goes inside the body. Not seeing the capillaries meant that the heart pumped blood towards the vessels and into a dead end. He couldn't understand where the blood that was being pumped goes to.

Explanation:

Leonardo da Vinci is considered one of the earliest persons to study the heart. Although he made an exceptional observation of the different parts of the heart, he couldn't track the capillaries. He didn't know that these tiny structures connected the arteries and the veins. He believed that the heart was meant to transfer heat from the liver going to the muscles. He also believed that the lungs helped cool the blood.

Many states offer free virtual programs that allow you to co-enroll and access advanced courses for free. Check with your local virtual programs to see which ones you can qualify for.

If you are unable to attend virtual programs, then you can likely find a online service (it will not be live most the time) that can teach you. Channels like CrashCourse are good, but I believe Khan Academy also provides videos, articles, and practice tests on anatomy.

I hope this helps, anatomy and physiology is a very useful and interesting course to take. Good on you for having the initiative =)

Answer:

Chemoautotrophs are able to synthesize their own organic molecules from the fixation of carbon dioxide.

Explanation:

These organisms are able to produce their own source of food, or energy. The energy required for this process comes from the oxidation of inorganic molecules such as iron, sulfur or magnesium.

Question: what is the sum of the first 100 whole numbers?? how am i supposed to work this out efficiently? thanks

The question you asked relates back to a famous mathematician, Gauss. In elementary school in the late 1700’s, Gauss was asked to find the sum of the numbers from 1 to 100. The question was assigned as “busy work” by the teacher, but Gauss found the answer rather quickly by discovering a pattern. His observation was as follows:

1 + 2 + 3 + 4 + … + 98 + 99 + 100

Gauss noticed that if he was to split the numbers into two groups (1 to 50 and 51 to 100), he could add them together vertically to get a sum of 101.

1 + 2 + 3 + 4 + 5 + … + 48 + 49 + 50

100 + 99 + 98 + 97 + 96 + … + 53 + 52 + 51

1 + 100 = 101

2 + 99 = 101

3 + 98 = 101

.

.

.

48 + 53 = 101

49 + 52 = 101

50 + 51 = 101

Gauss realized then that his final total would be 50(101) = 5050.

The sequence of numbers (1, 2, 3, … , 100) is arithmetic and when we are looking for the sum of a sequence, we call it a series. Thanks to Gauss, there is a special formula we can use to find the sum of a series:

S is the sum of the series and n is the number of terms in the series, in this case, 100.

Hope this helps!

The claim states that the weather on an island will continue to be most like the weather where orangutans live. To evaluate this claim, we need to consider several factors:

Without specific details about the island in question, it is difficult to make a definitive assessment. However, if the island is located within or near the equatorial belt and shares similar climatic conditions with Southeast Asian rainforests, it is more likely to have weather resembling that of orangutan habitats.

It is important to note that climate can vary even within a specific region, so a thorough analysis of the island's climatic data would be necessary to make an accurate comparison. Additionally, factors such as changes in global climate patterns over time may also impact the accuracy of this claim.

Source of unsaturated fats plants

Source of molecules for short-term energy ATP

Source of amino acids animal proteins.

Unsaturated fats are mostly found in plant-based foods including vegetable oils, nuts, & seeds. The most prevalent short-term energy molecule is ATP. There are four long-term energy storage molecules that are significantly bigger than ATP. Lipids, proteins, carbohydrates, & nucleic acids are examples. Animal proteins, such as beef, poultry, and eggs, are the finest suppliers of amino acids.

Animal proteins are really the easiest for your body to absorb and utilize. Complete proteins are meals that contain all nine essential amino acids. Unsaturated fats, that are liquid at room temperature, is considered healthy fats because they help lower cholesterol, reduce inflammation, normalize cardiac rhythms, and perform a range of other functions.

Hopetown

Explanation:

The farther from the equator the colder the air temperature. This is because the equator is the point on planet Earth that receives the largest amount of solar energy, so the regions that are above this line are the warmest in the entire planet. The further away from the equator a region is established, the less solar energy it receives, which is why the poles are so cold. In this case, we can say that the Hopetown temperature is colder than the kamine temperature.

The Devil's Hole pupfish has evolved a behavior described as "paradoxical anaerobism" as a result of adapting to a lack of oxygen in its habitat.

The correct answer is: A.

HABITAT: Having evolved to live within dry regions, deserts pupfish are capable of withstand conditions such as daily temperature changes of up to forty-five degrees Celsius, water temperatures around 120 degrees Celsius, extremely low concentrations of oxygen, salinity levels over twice as much of the ocean, and water temperatures above 110 degrees Fahrenheit.

Warm, salinized waters or salt streams are where they live, which would quickly kill a trout. For example, a Salt Creek pupfish can survive in seawater that is three times as salty. In Monument Valley National Park, they are plainly visible from a boardwalk.

Following the Hardy-Weinberg equilibrium theory, in a population of six million people, 1,080,000 individuals are healthy and carriers (heterozygous) for the trait.

The Hardy-Weinberg equilibrium is a theory that states that populations in equilibrium get the same allelic and genotypic frequencies generation after generation.

These populations do not evolve. No evolutive forces are acting on them.

Assuming a diallelic gene, frequencies are

Allelic frequencies

Genotypic frequencies

In a population in equilibrium,

We will consider these equations to solve the problem.

Because we have the frequency of the homozygous recessive genotype, we can get the allelic frequency.

Now, by clearing the equation p + q = 1, we can get the dominant allele frequency. And then, the frequency of the homozygous dominant genotype.

Finally, we can get the frequency of the heterozygous genotype

The number of individuals with each phenotype in the population is,

Winds travelling away from the equator are the wind pattern that the ocean temperature pattern best explains.

The process of water molecules freely interacting with the air when they are heated is known as evaporation. The constant evaporation of ocean water increases the warmth and humidity of the surrounding air, causing rain and storms to form and be delivered by trade winds.

Ocean currents serve as conveyor belts of warm and cold water, moving heat from tropical areas to the polar caps. The oceans of the world have major role in global warming.

WHAT IT SHOULD LOOK LIKE then the pH of 3 will have the least amount of growth followed by the pH of 5, 7, and 9.). This will happen because a lower pH means less carbonate which oysters require to build their shells.

Answer: Current plate movement can be tracked directly by means of ground-based or space-based geodetic measurements; geodesy is the science of the size and shape of the Earth. Ground-based measurements are taken with conventional but very precise ground-surveying techniques, using laser-electronic instruments. Sep 15, 2014

Explanation: Earth's land masses move toward and away from each other at an average rate of about 1.5 centimeters (0.6 inches) a year. That's about the rate that human toenails grow!

Geodesy, the science of measuring the Earth's shape and positions on it, allows the measurement of plate motion directly using GPS, the Global Positioning System. This network of satellites is more stable than the Earth's surface, so when a whole continent moves somewhere at a few centimeters per year, GPS can tell.
