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.

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

Answers
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.

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.
Answers
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.

What is the difference between near surface ozone and high altitude ozone?
Answers
The difference between near-surface ozone and high altitude ozone is that high altitude ozone is adequate ozone as it is a UV shield and the surface zone is destructive ozone as it is harmful to life forms.
What are the major reasons responsible for ozone depletion?The major reasons for ozone depletion include the excessive accumulation of greenhouse gases, CFCs, propellents, manufactured chemicals, etc.
High altitude ozone is found at the topmost height in the region of the stratosphere, while surface ozone is found just above the troposphere.
Therefore, it is well described above.
