You have colonies growing on a culture and are going to identify them. First, you do a Gram stain and viewing it on 1000x magnification, you see Gram positive cocci, no predominating arrangement. What test should you do to determine if it a staphylococcus or a streptococcus
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.

Which of the following statements are true about the esophagus?
The statements that are true about the esophagus are:
The esophagus is a muscular tube.The esophagus is the muscular tube of the digestive tract that develops from the pharynx to the stomach.
The esophagus moves food from the mouth to the stomach.This part of the digestive system is traversed by food, which enters through the mouth, passes through the pharynx, crosses the esophagus and reaches the stomach.
In this process, the esophagus has an active participation, since its walls contract to promote the advance of the food.
Therefore, we can conclude that the esophagus is a muscular tube that moves food from the mouth to the stomach.

The evolutionary species concept defines a species as: A. a group of populations that have shared a past and will have a shared future B. reproductively isolated populations C. smallest monophyletic taxa D. morphologically similar populations
Answer:
The correct option is A.
group of populations that have shared a past and will have a shared future
Explanation:
This is because evolutionary species concept is a concept that indicate a form of ancestry descendants or lineage of populations that descend from the same ancestors possessing similar characteristics which were inherited from the ancestry and these traits are evident in the future.

What are the 6 regions of the
human body from which hair can
be derived?
Answer:
Hair is made of a tough protein called keratin. A hair follicle anchors each hair into the skin. The hair bulb forms the base of the hair follicle. ... Blood vessels nourish the cells in the hair bulb, and deliver hormones that modify hair growth and structure at different times of life, if that answers your question.
Explanation:
The six (6) regions of the human body from which hair can be derived are:
1. Head.
2. Eyebrow.
3. Beard.
4. Pubic area.
5. Body.
6. Armpit (underarm).
Hair can be defined as a threadlike, keratinous filament that typically grows out of the epidermis. Also, an epidermis is the outer layer of the skin.
Basically, the hair comprises two main parts and these are:
The follicle.The hair shaft.Some of the macroscopic and microscopic properties of hair include:
Hair length.Hair color.Pigmentation of the cortex.Types of scales on the cuticle.Hair curliness.Pattern of the medulla.Generally, hair can be found or grow in different regions of the human body and these include the following:

Answer:
A. Purple: FF /White: ff
Explanation:
I did it too lol
Purple: FF /White: ff the principles of dominance and segregation to analyze the diagram, alleles would you expect in the F1 plants. Thus, option (a) is correct.
What is segregation?The Segregation Principle defines how pairs of gene variations are divided into reproductive cells. Gregor Mendel discovered the segregation of gene variants, known as alleles, and their accompanying qualities in 1865. During meiosis, allele pairs (different features of the same gene) are separated so that they can pass to distinct gametes.
The diagram was analyzed using the principles of supremacy and segregation. The principle of the impact in segregation was described as Purple: FF / White: ff. This inheritance pattern is known as partial dominance, which means that neither allele is completely dominant over the other: both genotypes can be seen at the same time.
As a result, the Purple: FF /White: ff the principles of dominance and segregation.
