Some of the smallest cells in the human body are red blood cells. They make up nearly half the volume of blood. A typical red blood cell is 8 µm across. The largest artery that blood flows through is the aorta, which is about 20 mm (2 cm) across. How many red blood cells would fit side-by-side across the aorta? Show your working.

Answers

Answer 1

Answer:

[tex]$1.6 \times 10^{-3}$[/tex]

Explanation:

Given data :

Size of a typical red blood cells = 8 µm

                                                     = 0.0008 cm

The size of the largest artery through which the blood flows, known as aorta

                                                     = 20 mm

                                                     = 2 cm

Thus the number of the red blood cells that would fit side by side across the aorta would be =   2 cm x 0.0008 cm

                          =    [tex]$1.6 \times 10^{-3}$[/tex]

Approximately how many mutations occur naturally in DNA per 10,000 bases?
A. 2
B. 2000
C. 200
D. 20

Answers

Explanation:

Modern methods indicate that the mutation rate is roughly one to two mutation per 10,000 genes per generation.

In human cells, approximately TWO (2) MUTATIONS occur naturally in DNA per 10,000 bases (Option A is correct).

The mutation rate (u) refers to the occurrence of new mutations in a given nucleotide sequence over time.

In human cells, the mutation rate is approximately 10⁻⁴ per generation.

Therefore, in a DNA sequence that has 10,000 base pairs of length, this value is equal to 2 mutations per generation (u = 2 / 10,000 = 10⁻⁴).  

In conclusion, approximately 2 MUTATIONS occur naturally in DNA per 10,000 bases (Option A is correct).

A specimen can be anything that is displayed regarding the subject. In labs the specimens can be chemicals, animals, plants, any objects, etc.

Specimens are displayed to learn about them, to see the actual version of that animal that can not be seen easily.

physical change is like cutting, changing shape etc, it the molecules that make it and the chemicals of it stay same

chemical change when it chemically changed such as cooking meat

The Answer is B

B. A copper rod is hammered into a thin sheet.

Physical change does not affect the chemical components of the material and the rod was only hammered to change it shape (thus altering a change in the physical aspect)

Each sales contract reserved the right of approval over the conduct of certain businesses on the property, including ski rentals. For fifteen years, DVRC permitted Christy Sports, LLC, to rent skis in competition with DVRCs ski rental outlet. When DVRC opened a new midmountain ski rental outlet, it revoked Christys permission to rent skis. This meant that most skiers who flew into Salt Lake City and shuttled to Deer Valley had few choices: they could carry their ski equipment with them on their flights, take a shuttle into Park City and look for cheaper ski rentals there, or rent from DVRC.
