Indicate which of the following observations can be made when observing growth on nutrient agar. Group of answer choices Gram reaction of growth Acid-fast morphology Amount of growth Opacity/clarity of colonies Color of colonies Presence or absence of endospores Shape and /or pattern of growth
Answers
Answer:
Amount of growth
Opacity/clarity of colonies
Color of colonies
Shape and /or pattern of growth
Explanation:
An agar plate is a Petri dish containing agar as a solid growth medium supplied with nutrients (i.e., an enriched medium), which enable to culture different microbes ranging from fungi to bacteria. Colony morphology is a widely used approach to describe the unique features of bacteria colonies growing on agar media. These colony features include, among others, shape (round, circular, punctiform, irregular), elevations/depressions (convex, concave, flat), textures (dry, moist, crusty, dull, shiny, mucoid, friable, rough), colors (cream, white, purple, gray, red, green, yellow, blue), etc.
The observation that could be made regarding the growth over nutrient agar would be:
C). Amount of growth
D). Opacity/clarity of colonies
E). Color of colonies
G). Shape and/or pattern of growth.
Observation
The growth of nutrient agar can be observed in above-mentioned ways. The area covered during the growth, the level of clarity amongst them, the color developed by them, and their size and formation as well.This assists in making worthy deductions about them.Thus, options C, D, E, and G are the correct answers.Learn more about "Morphology" here:

Many bacteria and fungi are important in the environment because they recycle nutrients, making them available for other organisms.
DECOMPOSERS:
Based on their role in the recycling of energy and nutrients in the environment, living organisms can be grouped as either producers, consumers or decomposers. Producers are organisms capable of synthesizing food on their own either by using sunlight (photosynthesis) or chemicals (chemosynthesis). They create the energy that is transferred in an ecosystem. Examples are green plants, algae etc. Consumers are organisms that depend on other organisms for their energy source or nutrients. Example include animals etc. Decomposers are organisms that degrade or breakdown dead organic matter, hence, returning nutrients to the soil to make them available for other organisms. Examples are some Bacteria, Fungi etc.Learn more: https://brainly.com/question/16599318?referrer=searchResults

How could a change in the carbon cycle lead to a change in the water cycle? (Give me an example of an increase in one process leading to an increase or decrease in the process of the other cycle)
Answers
Answer:
Higher rates of carbon fixation lead to increased respiration, energy production and CO2 + H2O excretion.
Explanation:
Inorganic carbon is fixed into high-energy polysaccharides by producers during photosynthesis and used by consumers in respiration to produce fuel, where it is produced as a waste product, along with water.
In photsynthesis...
6 CO2 + 6 H2O + light → C6H12O6 + 6 O2 Carbon Dioxide + Water + Light Glucose + OxygenIn respiration..
.C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP glucose+ oxygen → carbon dioxide+ water+ energyThus, changes in photosynthesis affect the ability of other organisms to respire and produce water. More fixation directly leads to increased respiration, production of ATP, and CO2 + H2O excretion.

Which of the following kinds of organisms do photosynthesis? Select all that apply.
Answers
Answer:
Plants, algae, cyanobacteria, and etc.
Explanation:
"Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth."
Plants, Algae, and some bacteria kinds of organisms do photosynthesis. So, the correct options are A, D and F.
What is Photosynthesis?The word “photosynthesis” is derived from the two words photo means “light” and synthesis means, “combining together.” which means “combining together with the help of light.”
Photosynthesis is defined as the process by which light energy is converted into chemical energy, which is then used to fuel cellular activities where chemical energy is stored in the form of sugars. Which are made of water and carbon dioxide.
Photosynthesis can also applies to other organisms besides green plants such as several prokaryotes such as cyanobacteria, purple bacteria and green sulfur bacteria.
Thus, Plants, Algae, and some bacteria kinds of organisms do photosynthesis. So, the correct options are A, D and F.
