The correct answer is C. Clavicle and scapula

Explanation:

The pectoral girdle, also called the shoulder girdle refers to a set of bones that connect the arm to the rest of the skeleton. In human beings and many other species, the pectoral girdle consists of the clavicle that is a long bone that goes from the shoulder to the sternum and the scapula that is a flat bone and goes from the upper zone of the arm to the clavicle. Additionally, in some species, the shoulder girdle includes a third bone called coracoid. According to this, the pectoral girdle consists of the clavicle and the scapula.

Immediately preceding the onset of an eating disorder in a woman, one would most likely find that she is Fat. There are 2 common eating disorders. Anorexia Nervosa which is a psychological and if not treated would be a life threatening disorder. The person suffering this usually have low body weight compared to their height since they do not usually eat as they think they already look fat while the second disorder which is Bulimia nervosa which is binge eating is characterized by self induced vomiting after eating food which they think is many.

within a forest ecosystem, there is a large amount of diversity among members of a warbler species. of the following stages of m

anzhelika [568]

Crossing over occurs between homologous chromosomes, and is closely involved in genetic variation. The stage that most contributes to diversity is stage C, where you can see chromosomes after crossing-over.

----------------------------

There are different mechanisms involved in producing genetic variation among descendants. These are,

Crossing-over between homologous chromosomes (prophase 1),

Random lining of homologous chromosomes (metaphase 1),

Random fertilization

The Crossing-over events occur between two homologous chromosomes in the equatorial plane and make the daughter cells genetically different from the original one.

The Chiasma is the position where two homologous chromatids interchange genetic information, giving a place for new genetic material or information to be provided to descendants.

After crossing over, homologous chromosomes get separated again.

In the attached imaged there are four different stages of meiosis.

Stage C is the one that contributes the most to diversity.

We can see that crossing over has already occurred between homologous chromosomes, and they have already interchanged segments.

In the image you will see the difference between chromosomes that has gone through the crossing over mechanism, and chromosomes that has not. The difference in color represents segments interchange and variation.

The best method to isolate single colonies is the ___________ plate, and the best method to count colonies is the ___________ pl

OverLord2011 [107]

Answer:

option a. streak, pour

Explanation:

The best method to isolate single bacterial colonies is the "streak-plating" method.

The "streak-plate" procedure is used to isolate pure cultures of bacteria or also colonies, from mixed populations by mechanical separation. Millions of cells form a colony, they grow in a cluster on an agar plate. With this method, a mixture of cells is spread over the surface of a agar-based nutrient in a petri dish, that makes that less bacterial cells are deposited at widely separated point on the surface and, after incubation, they develop into colonies.

On the other hand, the best method to count colonies is the pour plate method. It helps to enumerate bacterial cells in a mixed sample, often used to count the number of microorganisms in those samples, which are added to a molten agar medium before its solidification occur. The result is colonies uniformly distributed throughout the solid medium when the appropriate sample dilution is plated.
