Answer and explanation;

-There are advantages to being multicellular rather than unicellular. These include; allowing the organism to be larger, allowing cell differentiation (having different types of cells with different functions) , and also allowing the organisms to be more complex.

-Complex organisms often have specialized cells that carry out different functions. Having specialized cells and systems allows the process such as transport of nutrients and waste to and from all the cells of the body to occur.

Specialized cells refers to those cells that have develop certain characteristics which enable them to perform specific functions. Specialized cells are very important to muticellular organisms. In these organism, cell differentiate and specialize to form tissues, which come together to form different organs such as brain, heart, lungs, kidneys, etc. Examples of specialized cells in the body are neurons, muscle cells, red blood cells, sperm cells and leukocyte cells. The different organs formed by specialized cells perform different functions in the body.

The bones from an animal found at an archaeological dig have a C614 activity of 0.10 Bq per gram of carbon. The half-life of C61

erastova [34]

C14 is an isotope used in radiocarbon dating techniques to date organic matter remains. The age of these bones is approximately 6890 years.

<h3>What is Carbon 14?</h3>

Carbon 14, also known as radiocarbon, is a radioactive carbon isotope.

Isotopes are the atoms of the same element -carbon- that vary in neutrons and, hence, in their massic number. They are alternative forms of the same element.

The radioactive C14 nucleus contains 6 protons and 8 neutrons and has a half-life of 5730 years.

The term half-life is a reference. It means that an organism that has been dead for 5730 years has half the C14 amount or concentration than the same organism had when it was alive.

Knowing the half-life of an element is useful to determine the age of the dead matter.

C14 is used in radiocarbon dating techniques or methods to estimate the age of fossils. This is a reliable technique used for dating organic samples that are less than 50,000 years old.

Available data:

The half-life of C14 is 5730 years
Bones activity of 0.10 Bq per gram of carbon

To answer this question we can make use of the following equation

Ln (C14T₁/C14 T₀) = - λ T₁

Where,

C14 T₀ ⇒ Amount of carbon in a living body. We know, by bibliography, that living organism activity is 0.23 Bq per gram of carbon. So, C14 T₀ = 0.23 Bq/g

C14T₁ ⇒ Amount of carbon in the dead body. C14T₁ = 0.1 Bq/g

λ ⇒ radioactive decay constant = (Ln2)/T₀,₅

T₀,₅ ⇒ The half-life of carbon 14 = 5730 years

T₀ = Time when the organism was alive

T₁ = Age of bones

Let us first calculate the radioactive decay constant.

λ = (Ln2)/T₀,₅

λ = 0.693/5730

λ = 0.0001209

Now, let us calculate the first term in the equation

Ln (C14T₁/C14 T₀) = Ln (0.1/0.23) = Ln 0.4347 = - 0.833

Finally, let us replace the terms, clear the equation, and calculate the value of T₁.

Ln (C14T₁/C14 T₀) = - λ T₁

- 0.833 = - 0.0001209 x T₁

T₁ = - 0.833 / - 0.0001209

T₁ = 6889.99 ≅ 6890 years

The bones are approximately 6890 years.

What is the relationship between mitosis and cell division

Orlov [11]

Mitosis is the usual method of cell division, characterized typically by the resolving of the chromatin of the nucleus into a threadlike form, which condenses into chromosomes, each of which separates longitudinally into two parts, one part of each chromosome being retained in each of two new cells resulting from the original cell.

What are the characteristics of the vertebrate's nervous systems?

Delicious77 [7]

Answer:

Vertebrates contain nervous system which is highly specialized organ.

Explanation:

The nervous system is the complex system in the vertebrate body which is composed of central nervous system that contain brain,spinal cord and peripheral nervous system which contain cranial nerve, spinal nerve,involuntary nerve etc.

The nervous system contain neurons that mainly transmit signal to the different parts of the body.

The peripheral nervous sytem contain somatic and visceral part.

The grey matter and white matter are the 2 areas in vertebrate nervous system.
