What are things we can learn from examining hair? Three parts of hair?

Answers

Answer 1

Answer: The hair is an outgrowth or appendage that grows from a hair follicle.

Explanation:

The three parts of the hair are cuticle, cortex, and medulla. The cuticle is the hard part made up of scales with keratin protein, cortex is the inner pigmented part, and the medulla is the innermost part of the hair.

During hair examination the type of cuticular scales helps in determining the organism to which it belongs, diameter of the medulla also helps in determining the organism, the DNA analysis of the hair can link to its origin, the detection of heavy metal poisoning like lead, arsenic, and others. Drug abuse details can also be determined by the hair analysis.

Volcanoes can form near coastal regions where an oceanic plate [blank] below a continental plate

Answers

Answer:

Subducts

Explanation:

According to Merriam Webster and TheFreeDictionary, the definition of subduct is "A geologic process in which one edge of one crustal plate is forced below the edge of another." Since this sentence indicates that an oceanic plate sinks under the continental plate, therefore I believe the fill-in-the-blank word would be 'subducts' or a similar word.

Insects, like moths, are drawn to bright lights because they make it difficult for them to navigate. It's a common sight, particularly in the summer: The lights, like lamps, were surrounded by moths and other insects.

Most nocturnally dynamic moths are drawn to light, a peculiarity known as sure phototaxis. However, because they are phototactic, some species, like the Old Lady (Mormo maura), tend to avoid it.

No one really knows why moths are drawn to light, but there are a few theories, and they also like the smell of fermented sugar and ripe fruit, which are both food sources.

A botanist finds that when compared to pink flowers, the population of purple flowers is very high. Ten years later, the population of purple flowers is nearly gone, and the number of pink flowers has tripled. Why would this be?

Answers

Answer:

Because of the reduction or near extinction of the purple flowers noticed by the botanist Ten years after it was in abundance, this fall in the population could be caused by the unfavorable change in the plant's environment. While the pink flowers tripled because some factors in the environment were favorable for its growth.

Explanation:

From the question, it was mention that the botanist noticed at first purple flowers had more population than the pink flowers and that changed after 10 years when the population of the pink flowers tripled and purple flowers were nearly gone. Some of the causes that could be responsible are:

1. Disease and pest attack on the purple flowers.

2. The pink flowers developed a good survival mechanism even in adverse conditions.

3. Environmental stress could also come into play on the purple flowers.

4. Climate which initially supported the growth of the purple flowers had changed. Because variations exist in plants and the ideal conditions necessary for plant growths and proliferation varies among plants.

*anatomy & physiology question*

if you are at 120X and the field diameter is 8.0 mm what is the field diameter if you go to 30X magnification?

Answers

Answer:

32 mm

Explanation:

The field of view is the total area visible through the microscope . The diameter of the field of view can be measured.

There is an inverse relationship between the magnification and the field diameter. As magnifications decreases, the field diameter increases by the same proportion, and as magnifications increases, the field diameter decreases by the same proportion.

The relationship between field diameter and magnification is:

magnification of A * field diameter of A = magnification of B * field diameter of B

120X * 8 mm = 30X * B

B = 120X / 30X * 8 mm

B = 32 mm = 32000 μm

The field diameter of 30X magnification is 32 mm (32000 μm)
