List the order of vessels the blood travels after it leaves the heart to the point that it is returning to the heart.
Answer:
Blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs. Blood leaves the heart through the aortic valve, into the aorta and to the body. This pattern is repeated, causing blood to flow continuously to the heart, lungs and body.

Which process transfers energy from organisms at one stage in a food chain
to organisms at the next?
Tick the correct box.
reproduction
feeding
movement
photosynthesis
1 mark
Answer:
feeding
Explanation:
when an organism eats another, it gets energy from it. That energy is passed along the food chain
The process by which energy is transferred from organisms at one stage in a food chain to organisms at the next is by feeding, which is present in the second option, as through the eating process and the predator-prey relationship, energies pass.
What is the significance of the food chain and the energy transfer?The food chain in nature is made up of many trophic levels, where one trophic level animal preys on other animals or plants and obtains food from them, so when the animal is eaten by other animals, the energy content passes from one to another, and the energy content from plants continues to decrease to the topmost trophic levels.
Hence, the process by which energy is transferred from organisms at one stage in a food chain to organisms at the next is by feeding, which is present in the second option, as through the eating process and the predator-prey relationship, energies pass.

The leg muscles of a sprinter would differ from a marathon runner in that ________. The leg muscles of a sprinter would differ from a marathon runner in that ________. per gram, the sprinter's muscles would have more mitochondria than the marathon runner's muscles the marathon runner's muscles would have a greater rate of contraction than the sprinter's muscles per gram, the marathon runner's muscles would contain more myoglobin than the sprinter's muscles per gram, the sprinter's muscles would use more oxygen than the marathon runner's muscles
Answer:
The correct answer is - per gram, the marathon runner's muscles would contain more myoglobin than the sprinter's muscles.
Explanation:
Marathon runners have smaller leg muscles and thinner quads and calves as marathon runners require slow-twitch muscles while in sprinters the fast-twitch muscle requires. Slow-twitch muscles of marathon runners have more amount of myoglobin, per gram than fast-twitch muscles.
Myoglobin acts as local oxygen storage that provides oxygen to the muscles in case of less oxygen supply than required temporarily and a marathon race is an intense exercise or activity that requires more oxygen.

The digestive system carries out chemical digestion while the excretory system does physical digestion.
Answer:
A. The digestive system fuels the cells and the excretory system rids the body of the cells’ waste.
Explanation:
got it right on edg quiz (see pic)
hope this helps :)
All nutrients that enter the circulation are processed by the digestive and excretory systems simultaneously, with the exception of oxygen, which is taken in by the respiratory system. The correct answer is a) The digestive system fuels the cells and the excretory system rids the body of the cells’ waste.
What is the digestive and excretory system?Nutritive substances are absorbed by the digestive system, and any that are not are expelled. By continuously purging the blood, the excretory system works in tandem to remove metabolic waste products from cells throughout the body.
The digestive system takes in the nutrients and water from the diet. All across the body, the circulatory system delivers nutrition, water, and oxygen to cells. The respiratory system, the excretory system, and the skin all remove waste from the cells.
The excretory system filters the bloodstream for nutrients and gathers unneeded components in your urine for disposal, whereas the digestive system absorbs nutrients, collects them, and then eliminates the undigested solids (feces).
Therefore, the correct answer is a).

Which of the following is the best representation of the limiting factors affecting the elk population in this ecosystem?
O Number of scavengers, number of wolves, number of scientists studying Yellowstone.
Number of scavengers, and harshness of winter
Number of wolves, and harshness of winter.
The elk have no limiting factors
Answer:
Number of wolves, and harshness of winter.
Explanation: I took the test
The combination of factors that is capable of limiting the population of elk in an ecosystem would be the number of wolves and the harshness of winter.
The limiting factors of a population are those factors that hinder the population of an organism from increasing unlimitedly. In other words, limiting factors hinder populations from reaching their biotic potentials.
Limiting factors can be density-dependent if they have correlations with the density of species or density-independent if they have no correlation with an organism's density.
Wolves generally prey on elks, so they limit the growth of elk's population in an ecosystem. A harsh winter will also limit the overall growth of the population of elk in an ecosystem.
Scavengers cannot be a limiting factor to elk's population because they only feed on carcasses.
