Legumes are able to form a symbiotic relationship with nitrogen-fixing soil bacteria called rhizobia. The result of this symbiosis is to form nodules on the plant root, within which the bacteria can convert atmospheric nitrogen into ammonia that can be used by the plant.

What causes thermal pollution in rivers?
A) automobile exhaust
B) factory smokestacks
C) solar radiation
D) nuclear power plants

Answers

Answer:

D.) nuclear power plants

Explanation:

Thermal pollution is defined as a sudden increase or decrease in temperature of a natural body of water, which may be ocean, lake, river or pond by human influence. This normally occurs when a plant or facility takes in water from a natural resource and puts it back with an altered temperature

Thermal pollution is the degradation of water quality by any process that changes the ambient water temperature.  A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers.

List 4 different organisms from the same food chain in the order of how the energy flows.

Answers

Answer:

Worm, Bird, Snakes, Hawks.

Explanation:

Hope this helps in anyway,

Worm, Bird, Snakes, Hawks are the  order of how the energy flows.

What is Food chain?

Food chain, in ecology, the sequence of transfers of matter and energy in the form of food from organism to organism.

Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant. Plants, which convert solar energy to food by photosynthesis, are the primary food source.

Because energy, in the form of heat, is lost at each step, or trophic level, chains do not normally encompass more than four or five trophic levels. People can increase the total food supply by cutting out one step in the food chain.

Therefore, Worm, Bird, Snakes, Hawks are the  order of how the energy flows.

Which type of biotechnology would be used by scientists who use the egg cell of an endangered animal to increase the population of the animal?

Genetic engineering because the genes of the animal would be modified
Genetic engineering because it is always helpful for the environment
Cloning because offspring that are exact copies are produced
Cloning because offspring would be produced in a few hours

Answers

Answer:

the 3rd option: Cloning because offspring that are exact copies are produced

Explanation:

Biotechnology is a field of science that comprises biology combined with technology. It utilises the living system with the technology to build products.

The correct answer is:

Option C. Cloning because offspring that are exact copies are produced.

This can be explained by:

Cloning is a mode of reproduction in which the replica of the parent is produced as offspring.

The genetic content of the offspring is the same as that of the parent. Hence all the traits and the characters remain preserved.

Therefore, for deliberately producing the endangered species cloning technique can be employed.

Why do you think the food dye mixed at different rates?

Answers

Answer:

The food coloring mixes through the hot water faster than it mixes with the cold water. This is because in hot water, the water molecules have more energy and are moving faster than the molecules of cold water. This makes it easier for the dye to get mixed throughout the hot water.

Hope this helps!! (Please mark Brainliest if possible!!)

The hot water causes the food coloring to diffuse faster. At higher temperatures, particles move faster. This faster movement allows diffusion to occur more quickly

Explanation:  Community, also called biological community, in biology, an interacting group of various species in a common location. For example, a forest of trees and undergrowth plants, inhabited by animals and rooted in soil containing bacteria and fungi, constitutes a biological community.

An interacting group of the species is called a community. All of the deer, raccoon, trees, birds, sky, and water in a distinct area makes the community.

What is a community?

A community is also called a biological community and consists of the interacting species or the organism that lives together by depending sometimes on each other and some abiotic factors.

In an ecosystem, the potential interacting species live together in a particular area and influences each other in a certain way by sharing the same environment will be called the ecological or the biological community.

In a deer community, the related organisms like a raccoon, birds, water, rock, air and deer live and interact together in a defined area.

Therefore, option A. all the deer, rocks, air, water, sky, birds and trees make the biological community.
