Answer:A culture or growth medium

Explanation: A culture or growth medium contains essential nutrients that aids in the growth of microorganisms. A culture medium can be in liquid form or solid form. It is very important to make sure that a culture or growth medium is sterile and free from any form of contamination. The main function and importance of a culture or growth medium is to ensure that microorganisms grow in a sterile environment that has all the major and essential nutrients required for their growth and to preserve them against any form of harm or contamination such that when these organisms are needed they can be used.

Answer: MEDIUM

A sterile substance that allows for microorganism multiplication is known as a medium.

Explanation: A medium is a microbiological substance either solid or liquid that is used to grow bacteria.

A medium contains everything a bacteria needs to grow outside the body and under laboratory conditions. It is made free of all forms of viable microbes(sterile) and enriched with special growth factors that aid in the growth of organisms that have complex or distinct nutritional requirements.

These nutrients may be organic substances such as blood, serum extracts of animals,plants or yeast, meat extracts(cell secretions), or haemoglobin.

lions [1.4K]

The right answer is a.anatomy involves symmetry.

In the anatomy of multicellular animals with bilateral symmetry (which form the subregion of bilateria), there are many even organs, that is to say composed of two symmetrical halves, generally positioned on both sides of the median plane. This is the case, for example the human brain that includes two hemispheres, two amygdalas and two hyppocampus, a left and a right.

Fiesta28 [93]

Answer:

W- developed seeds

X-angiosperm

Well for one, these two are the only things w/ a referrable image (I'm not sure if that's a word :-)) Another thing is angiosperm literally means flowering plant and a tomato is a ripe, or flowering, plant. W is an image of seeds that are at mid stage in there developing process, so it is clearly the answer. Correct me if im wrong :-D.

1. List 2 interactions between the earth spheres and the water cycle.
Harrizon [31]

Answer:

The carbon cycle, as the nitrogen cycle, occurs in all the spheres: Biosphere, Atmosphere, Geosphere and Hydrosphere.

Explanation:

Most Earth events involve interaction between multiple spheres. For example, rain is the movement of water (the hydrosphere) from the atmosphere to the lithosphere where it collects in lakes, rivers, or streams. Water is an important resource for inhabitants of the biosphere.

The Atmosphere-contains all the air in Earth's system. The upper portion of the atmosphere protects the organisms of the biosphere from the sun's ultraviolet radiation. It also absorbs and emits heat. This sphere is also where weather occurs.

The nitrogen cycle occurs in all the spheres and ecosystems. It passes through rocks, water, atmosphere, plants, etc.

In atmosphere and biosphere: Nitrogen is about 78% of the gases in the atmosphere an it’s a essential component of the living organisms. It enters plants through the microorganisms that convert this nitrogen into ammonia. After this conversion, the plants absorb this substance. It can pass to animals when they eat these plants. Then, when they urinate, bacteria convert ammonia to nitrogen again and it returns to the atmosphere.
