Answer: The test that's should be done to determine if it's a staphylococcus or a streptococcus is a BIOCHEMICAL TEST known as CATALASE TEST.
Explanation:
In the laboratory diagnosis of microbiology samples, GRAM STAINING technique is used to identify bacteria pathogens in specimens and cultures by their gram reactions. The bacteria may be either gram positive or gram negative.
Gram positive bacteria when views with ×100 oil immersion stains dark purple with crystal violet and are not decolorize by acetone or ethanol. Examples of gram positive bacteria include:
--> Staphylococcus
--> Streptococcus
--> Clostridium
--> Corynebacterium
Since a gram positive cocci was identified without a predominating arrangement, further biochemical test known as catalase test should be carried out to determine if the cocci is staphylococcus or a streptococcus.
CATALASE TEST is used to differentiate those bacteria that produce catalase enzyme such as staphylococcus from non- catalase producing bacteria such as streptococcus. Catalase acts as a catalyst in the breakdown of hydrogen peroxide to oxygen and water. An organism is tested for catalase production by bringing it into contact with hydrogen peroxide. Bubbles of oxygen are released if the organism is a catalase producer, therefore staphylococcus but if no bubbles are observed, it's a streptococcus.

Bones grow in diameter due to bone formation
Answer:
Osteoblasts move in and ossify the matrix to form bone. Even though bones stop growing in length in early adulthood, they can continue to increase in thickness or diameter throughout life. The increase in diameter is called appositional growth.
What causes matter to be in a particular state (phase)?
Answer:
In the physical sciences, a phase is a region of space (a thermodynamic system), throughout which all physical properties of a material are essentially uniform. Examples of physical properties include density, index of refraction, magnetization and chemical composition. A simple description is that a phase is a region of material that is chemically uniform, physically distinct, and (often) mechanically separable. In a system consisting of ice and water in a glass jar, the ice cubes are one phase, the water is a second phase, and the humid air is a third phase over the ice and water. The glass of the jar is another separate phase. (See state of matter § Glass)

Most living organisms need to take in oxygen to survive. What is responsible for
providing most of this oxygen?
fish and phytoplankton
plants and seaweed
seaweed and phytoplankton
coral and fish
Most living organisms need to take in oxygen to survive. It is responsible for plants and seaweed.
What are seaweeds?
Some seaweeds are microscopic, such as the phytoplankton that live suspended in the water column and provide the base for most marine food chains. Some are enormous, like the giant kelp that grow in abundant “forests” and tower like underwater redwoods from their roots at the bottom of the sea.
Most are medium-sized, come in colors of red, green, brown, and black, and randomly wash up on beaches and shorelines just about everywhere.
The vernacular “seaweed” is a bona-fide misnomer, because a weed is a plant that spreads so profusely it can harm the habitat where it takes hold.
Therefore, Most living organisms need to take in oxygen to survive. It is responsible for plants and seaweed.

Which is not a cost for organisms that sexually reproduce?
Answer:
Identical shape and structure.
Explanation:
Those organisms that reproduce sexually have high variations and differences between the parent and its offspring. They are not identical to each other because the offspring gains half characteristics from male parent and half from the female parent making it different from its parent. Identical feature is present in the organisms that reproduce through asexually means from only one parent so the identical shape and structure is not the cost of sexual reproduction.

Which of the following best describes the difference between population size and population density?
A. Population density measures the abundance of an organism, whereas population size measures the distribution
B. Population size measures the abundance of an organism, whereas population density measures the distribution
C. Population size measures abundance, but population density measures how rapidly the size changes
D. Both variables measure abundance, but population density takes the into account the size of individuals, not just the number of individuals in the population
E. None of these descriptions are correct
Population size refers to the number of individuals, while population dendity refers to the number of individuals per unit of area or volume. The correct option is E. None of these descriptions are correct.
------------------------------------------------
Before answering the question, let us review the concepts of population size and density.
Population size refers to the number of individuals composing a population.Population size might determine the destiny of the population.
A small population has more chances to get extinct than a bigger-sized population.
Density refers to the average number of individuals of the same species per unit of area or volume. This measure may be more significant than population size.
To estimate population density there are two possible methods: Direct methods and indirect methods.
Abundance indexes are the parameters related to density, and they reflect changes that might happen in the target population density. They are commonly used to compare population sizes.
According to these concepts, the correct option is E. None of these descriptions are correct.

What is the main adaptive advantage of the C4 and CAM photosynthesis strategies over C3 photosynthesis?
a.They make it possible for the plant to use the Calvin cycle during the day.
b.They allow the plant to synthesize glucose without CO2.
c.They allow the plant to hold its breath and still perform photosynthesis.
d.They allow the plant to synthesize glucose under hot conditions.
Answer:
D. They allow the plant to synthesize glucose under hot conditions.
Explanation:
C4 and CAM photosynthesis strategies allow for plants to produce glucose in hot and dry conditions.
Plants such as cacti, which live in hot conditions, have the advantage from their C4 and CAM systems.
In contrast to C3 photosynthesis, C4 and CAM systems allow plants to get more CO2 from the air and help them conserve water.
This then allows them to efficiently create glucose with the CO2.
So, the correct answer is D.
Answer:
D. they allow the plant to synthesize glucose under hot conditions.
