TO PEOPLE WHO HAVE THIS ASSIGNMENT:

The answer is below:

A red blood cell that’s just returned from delivering oxygen and brought back carbon dioxide would be in the right atrium. When the atrium contracts, the cell is pumped into the right ventricle. When that ventricle contracts, the red blood cell is pumped out of the heart through the pulmonary artery to the lungs.In the lungs, the red blood cell enters tiny blood vessels that come into close contact with the walls of the alveoli air sacs of the lungs. The carbon dioxide in the red blood cell passes through the walls into the alveoli while the oxygen in the alveoli air passes into the red blood cell. The red blood cell then returns to the heart via the pulmonary vein.From the pulmonary vein, the red blood cell enters the left atrium of the heart and then the left ventricle. The red blood cell is pumped out of the aorta artery and eventually reaches the capillaries leading to the individual cells. There the cells absorb the oxygen from the red blood cell and pass on their waste carbon dioxide. The red blood cell returns to the right atrium of the heart via the veins to complete the cycle.

The circulatory system transports blood and other materials into the lungs and blood vessels.The circulatory system works with the respiratory system to make sure that oxygen-rich blood can flow through the body.
The respiratory system is where gas exchange occurs in the heart, arteries, veins, and capillaries.The respiratory system supports your circulatory system with air, or more specifically oxygen, which is sent to other organs from the arteries.

Here is an example:
My model is different from the actual system because I didn’t include the lungs and it is not the real thing. It is also different because in real life, the heart would not be cut in half.Some of the limitations of a model are that it doesn't move like a real heart would and you wouldn’t be able to see it in action.

When during meiosis does crossing over happen?

Answers

Answer:

prophase

Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I. By meiosis II, only sister chromatids remain and homologous chromosomes have been moved to separate cells. Recall that the point of crossing over is to increase genetic diversity.

What are the FIVE ways an object's motion can change?

Answers

Answer: An object's motion can change physically by humans, Physically by humans The action from a force can cause an object to move or can speed up accelerate, to slow down (decelerate), to stop, or to change direction. Since any change in velocity is considered acceleration, it could be said that a force on an object results in the acceleration of a object.

Explanation: please can I get brainliest

Motion is defined as the phenomena where an object moves from one point to another. Usually, a force has to act on the object for it to be in a state of motion.

Mathematically, motion has to do with:

The image shows the beak shapes of four different tinches observed by Charles Darwin on the Galapagos Islands Darwin observed that broad-boaked inches
prefer to eat large, hard seeds, while finches with narrow beaks cat small, soft seeds
What did Charles Darwin infer from this study that led to the development of the Theory of Evolution?
Anches with broad breaks have Nigher survival rules than tinches with nurow beaks
Finches with narrow beaks gradually evolve broader beaks to feed on all types of seeds
The finches evolved from different ancestors with different shapes of beaks
. The finches evolved from a common ancestor and developed different break shapes to adapt to the food available

Answers

Answer:

The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.

Explanation:

On the islands, Charles Darwin discovered several species of finches. He found out that different species of finches varied from island to island. Besides elaborating his thoughts on natural selection, this also helped him in his investigation on the evolutionary changes of the finches. Beaks changed as the birds developed different tastes for fruits, seeds, or insects picked from the ground or cacti. Long, pointed beaks made some of them more fit for picking seeds out of cactus fruits. Shorter, stouter beaks served best for eating seeds found on the ground.

Natural selection is the theory behind evolution put forth by Charles Darwin. Given the scarcity of resources in nature, animals with heritable features that promote survival and reproduction will typically produce more offspring than their contemporaries, leading to an increase in the frequency of such traits across successive generations.

Which observations about the Galapagos Islands did Charles Darwin make?

He discovered a remarkable population of plants, birds, and reptiles in the Galapagos that had evolved independently of the mainland, but that frequently differed on nearly identical islands next to one another and whose characteristics he could only explain by a slow evolution of the various species.

Charles Darwin discovered a number of finch species on the islands. He discovered that several finch species vary from island to island. The Galapagos Islands are well-known for being the location where Charles Darwin discovered many previously unknown species of animals, which inspired him to develop the theories of natural selection, survival of the fittest, and evolution.

They eat insects which and are then eaten by raptors.

Answers

They eat rodents and are eaten by owls and hawks

They are important because without them, the rodent population could become too numerous. Rodents like to chew on tree roots and other plants for nutrients, but this kills the plant. Too many rodents can cause a mass imbalance leading to the death of hundreds of other animals

The rattlesnakes are necessary to the balance of life in a forest as they eat rodents and are eaten by owls and hawks. Therefore, option (A) is correct.

What are the characteristics of rattlesnakes?

Venomous rattlesnakes belong to the genera Crotalus and Sistrurus, which are members of the subfamily Crotalinae. All poisonous snakes are snakes.

Rattlers are profoundly particular, venomous reptiles with huge bodies and triangle-molded heads. Because of their distinctive "rattle" at the tip of their tails, they are one of the most well-known groups of snakes.

Answer:

water moving from the beaker into the test tube

Explanation:

this was just on a quiz i had and it showed me the right answers after i finished

Osmosis can be used to explain the increase in fluid in the test tube that was observed after one hour.

Osmosis is the movement of water molecules through a semipermeable membrane from an area of low solute concentration to an area of high solute concentration. In this arrangement, the pure water in the beaker has a lower concentration of solute than the starch solution in the test tube.

Water molecules can pass through the dialysis membrane, but larger solute molecules such as starch cannot. Since the concentration of solute in the starch solution in the test tube is higher than in the water in the beaker, the water molecules move through the membrane to the beaker. This flow of water in the test tube increases the level of the liquid by increasing its volume. Therefore osmosis can be used to explain the rise of liquid in a test tube.

Help!!!! Can anyone answer this lab questions below about mitosis!!!!

Answers

Answer:

Mitosis is a division of a eukaryotic cell in which the chromosomes are evenly distributed among the daughter cells.

In multicellular organisms, both sexual and asexual reproduction is followed by cell division, which ensures the growth and development of the organism. In addition, cell division is necessary to replace dead cells and repair injuries. New cells are constantly being added and old ones are being destroyed. About a hundred thousand more cells are created every second, and of course the same number dies. The new cells start with the division of the source cell. The cells formed in this way are called daughter cells. Stem cells can gradually divide into all the different cells in the body through mitosis.

Most of the body's cells are constantly renewed by mitosis, but there are also so-called irreplaceable cells that are formed only once in a lifetime for the life of the organism and do not regenerate by mitosis.
