List the differences between the hearts of vertebrates that live in water and the hearts of vertebrates that live on land. List the similarities.

Answer: All vertebrates have circulatory systems based on a common plan, and so vertebrate systems show much less variety than do those of invertebrates. Although it is impossible to trace the evolution of the circulatory system by using fossils (because blood vessels do not fossilize as do bones and teeth), it is possible to theorize on its evolution by studying different groups of vertebrates and their developing embryos. Many of the variations from the common plan are related to the different requirements of living in water and on land.

Help me with this question please I’m close to getting a 100 please

Use the scenario below to answer the following question

Jerimiah and Nicko were discussing how well a vehicle uses its energy. They add a gallon of gasoline to the vehicle and observe the vehicle as their friend drives it in a circle around them. Jerimiah and Nicko hear the sound of the running engine, feel heat coming off of the exhaust and off the engine, and can see the vehicle move around them. After doing calculations they realize the vehicle did not travel nearly as far as they thought it would when it used the gallon of gasoline. Jerimiah claims that the energy must have been destroyed during its use, which is why they both heard the engine noises and felt the heat coming off. Nicko claims that the energy could not have been destroyed, but cannot determine what happened to all of the energy.

What can Nicko say that will explain why the energy was not destroyed during their test?

5. What school was Virchow founder of? So what types of organisms was he observing the most?

Fun Fact of the day: (Science Edition) Many of the cells in your body are 0.01 mm long- one hundredth the size of an ameba. How many body cells would you have to stack end to end to equal your height? (This is not a question for me for school I just like to learn and ask fun questions on brainly that are SCHOOL RELATED)

1.what does the term conclude mean?


2.What is the relationship between an allele and a gene?


3.What is the purpose of a Punnett square?

Look at the following diagram of the carbon cycle. An image of carbon cycle is shown. The sun, a cloud, two trees, one on the left and the other on the right, an animal, lake, and a factory are shown in the image. An arrow is shown from the sun towards the left tree marked A. The sun is marked B. There is an arrow from the air above the clouds, marked C, towards the left tree. An arrow from a location close to the ground marked D points towards Dead Organisms, which is a label under the animal. An arrow marked E points from the right tree straight up to the clouds. An arrow marked F points from the animal straight up to the clouds. An arrow marked G points from the factory towards the air above the clouds, C. There is an arrow pointing from the air to the lake labeled Carbonates in Water, an arrow pointing down from dead organisms to Fossils and Fossil Fuels, and an arrow from Fossils to the factory. Which of the following facts is best represented by the arrow pointing from C to A? The energy stored in atmospheric carbon dioxide is conserved because it is used to create new forms of energy present in decomposed plants. The energy stored in atmospheric carbon dioxide is conserved because it is transformed into glucose during photosynthesis. The chemical energy present in carbon dioxide is reduced when it is converted into chemical energy in glucose. The chemical energy present in carbon dioxide is used up completely during the burning of trees.

Which terms are listed in the correct order from largest to smallest? *

A. Genes, DNA, Chromosomes, Nucleus, Cell
B. Cell, Nucleus, Gene, DNA, Chromosome, Gene
C. DNA, Nucleus, Cell, Gene, Chromosome
D.Cell, Nucleus, Chromosome, DNA, Gene
