Oxygen-poor blood flows out of the heart and into the lungs. Nutrients and oxygen are sent to other cells and parts of the body. The blood then returns to the heart to begin the process again. Which of the body's systems is the above process describing? Answers (A) -The skeletal system (B)-The digestive system (C)-The respiratory system (D)-The circulatory system
Answer:
(D)-The circulatory system
Explanation:
lol just did it
and pls give me thanks
The circulatory system is the system which consist of blood vessels, heart, and blood. The main function of this system is the transport of oxygen and minerals to all the cells of body. Thus, the correct option is D.
What is Circulatory System?The circulatory system of body consists of all the blood vessels, blood and heart. In this system, blood travels through different blood vessels (arteries, veins, and capillaries) in all parts of the body.
The blood is the main fluid of the body that contains hemoglobin protein which is responsible for the transport of oxygen and carbon dioxide in the body. The blood exchanges gases at the surface of alveoli in the lungs and sends the blood to the heart, heart pumps the blood to all the cells of body.
Therefore, the correct option is D.

Janelle thinks that genetic engineering could be used to
make a larger fruit rather than cloning the fruit. Which would best support her point of view? A. Genetic engineering does not cost as much.
B. Genetic engineering does not result in genetically identical organisms. C. Genetically engineered foods never cause allergies in people. D. Genetically engineered foods have not been modified.
Genetic engineering is the process by which scientists choose a particular group of genes and insert them into an organism in such a way that the resulting features will be beneficial to the organism. Therefore, option (B) is correct.
What is genetic engineering?The modification and manipulation of an organism's genes through technology is known as genetic engineering, often referred to as genetic modification or genetic manipulation.
Genetic engineering, often known as genetic alteration, is a technique that modifies an organism's DNA using technology developed in labs. This could entail altering a single base pair (A-T or C-G), erasing a section of DNA, or incorporating new DNA. Therefore, option (B) is correct.

A lake in Minnesota was thriving with black bass and bluegill. These particular fish build nests on the sandy bottom of the lake. Now, ecologists are finding that over time a layer of humus has slowly been covering the pond. The ecologists are noting that the populations of black bass and bluegill are declining, and the fish that are able to make nests in humus are rising in numbers.
The ecologists can probably conclude that this event is an example of:
commensalism
parasitism
primary succession
succession
Answer:
Explanation:
https://quizizz.com/admin/quiz/5c9100e1202f89001c843569/stages-in-aquatic-ecological-succession
The event described, where a layer of humus covers the sandy bottom of the lake and affects the fish populations, is an example of succession.
Succession is the process of ecological change over time in a particular area. It involves a series of predictable and sequential changes in the composition and structure of an ecosystem.
In this case, the gradual accumulation of humus, a layer of decomposed organic matter, is altering the habitat conditions in the lake.
The decline in the populations of black bass and bluegill, which build nests on the sandy bottom, can be attributed to the changing habitat.
The humus layer is likely making it difficult or impossible for these fish to construct their nests. On the other hand, fish that are capable of making nests in humus, possibly adapted to this type of substrate, are increasing in numbers.
Therefore, the observed changes in fish populations and the altered habitat due to the accumulation of humus indicate a shift in the ecological community over time, which is a characteristic of succession.

What is the difference between glucose and ATP?
Glucose is a storable form of energy, while ATP is a usable form of energy.
ATP is a storable form of energy, while glucose is a usable form of energy.
ATP is only a usable form of energy, but glucose can be used and stored.
Glucose is only a storable form of energy, but ATP can be used and stored.
The main difference between glucose and ATP is that Glucose is a storable form of energy, while ATP is a usable form of energy.
Glucose is storable form of energy because it can't be used as energy until it can be broken down by mitochondria of the cell while on the other hand, ATP is the usable form of energy which we can get from the break down of glucose molecules. Our cells use ATP as a fuel to do various activities of the cell so we can conclude that in glucose, energy is present in stored form whereas ATP is used as energy in various activities.

9) List these biomes in order from the greatest to least diversity (temperate
deciduous forest, tropical rain forest, temperate rain forest).
Tropical rainforest, temperate deciduous forest, temperate rainforest
I'm not too sure if the temperate forest is more diverse than the rainforest, so sorry if I'm wrong. Tropical rainforests are the most diverse because of the humidity, which is water. The water helps the soil stay healthy, which makes more plants, which makes more animals and insects.
I hope this helps! Good luck!
The biomes in order from the greatest to least diversity will be tropical rainforest, temperate deciduous forest, and temperate rainforest.
Tropical rainforests refer to the rainforests that occur in areas that have no dry season.
The temperate deciduous forest refers to a biome that always changes. It has seasons such as winter, spring, summer, and fall.
Temperate rainforest refers to the broadleaf or coniferous forests that receive heavy rain. This condition supports ferns, shrubs, etc.
It should be noted that the biome with the greatest diversity is tropical rainforest while the least is the temperate rainforest.
