Restriction endonucleases cut DNA at specific sites, known as recognition sites, to produces DNA fragments useful for cloning. Restriction enzymes or restriction endonucleases are DNA cutting enzymes found in bacteria. Each restriction enzyme recognizes one or a few restriction sites. When it finds its target sequence, it makes a double stranded cut in the DNA molecule.

What would be the physical sign that a bone cannot continue longitudinal growth?
faltersainse [42]

Answer:

c) The presence of an ephiphyseal line

Explanation:

The options should be:

a) the presence of osteoblasts

b) the presence of osteons

c) The presence of an ephiphyseal line

d) the presence of hyaline cartilage on the ends of the bone

Explanation:

In vertebrates, the epiphyseal line is formed once the bone is completely grown. This occurs inside a plate known as the epiphyseal plate.

From the age of 18 to 21, the bone stops growing and the cartilage inside this plate gets replaced by bone. However, bones can keep growing in width until we are approximately 25 years old.

Therefore, the physical sign that indicates that a bone cannot continue longitudinal growth would be the presence of an ephiphyseal line.

Round the number 14.587020 to 4 significant digits. a. 14.59 b. 14.58 c. 14.587 d. 15.00 Please select the best answer from the
gregori [183]

Answer:

A. 14.59

Explanation:

Firstly, rounding a number means making a number simpler but keeping its value close. So rounding 14.587020 means making it look less complex but making sure the rounded value is within range of the original value.

Next, we have to know that to round a number;

* Digits below 5 (<5) rounds down the next digit to their left i.e. we leave the digits the same and turn the rounding digit to 0.

* Digits above 5 (>5) rounds up the next digit to the left i.e. we add 1 to the next digit

Next, to round to 4 significant digits means we want to see only the first four non-zero digits in our value. Note that, all non-zero digits i.e. 1-9 are significant

Hence, 14.587020 will be:

= 14.587020

= 14.58700

= 14.59000

We have four (4) digits which are non-zero already, hence we stop here and remove all zeros to the right

Hence, 14.587020 to 4 significant digits is 14.59 i.e. 14.587020 ~ 14.59

An aquifer is a rock layer that stores and allows the flow of groundwater. Compared to other types of rock layers, how permeable
AVprozaik [17]

Highly porous and permeable

Explanation:

Compared to other types of rock layers, an aquifer is highly porous and permeable.

Aquifers are always the target when prospecting for ground water in a formation.

  • Porosity is the amount of void spaces in a rock.
  • Aquifers are highly porous .
  • Permeability is the inter-connectivity of the void spaces and their ability to transmit fluids.
  • Aquifers have very high permeability compared to other rock types.

In terms of permeability and porosity, an aquifer is higher porous and permeable.
