Answer: Cell Size. At 0.1–5.0 µm in diameter, prokaryotic cells are significantly smaller than eukaryotic cells, which have diameters ranging from 10–100 µm (Figure 3.7). The small size of prokaryotes allows ions and organic molecules that enter them to quickly spread to other parts of the cell.

Which sustainable building practice does the photograph show?
A. Using a green roof to capture carbon and reduce a building's
energy costs
B. Reusing old bottles and cans as insulating building materials
C. Reducing fossil fuel consumption and its associated pollution
D. Replacing wilderness with buildings to reduce the absorption of
carbon dioxide
Reusing old bottles and cans as insulating building materials is the sustainable building practice. Therefore, option (C) is correct answer.
Sustainable building practices aim to minimize the environmental impact of construction and operation of buildings while enhancing the health, well-being, and productivity of occupants. These practices involve incorporating environmentally responsible methods and materials into the design, construction, and operation of buildings.
Therefore, reusing old bottles and cans as insulating building materials is the sustainable building practice.

The half-life of potassium-40 is 1.3 billion years. If a rock specimen contained 1g of
potassium-40 when it was formed, how much potassium-40 would be left if the rock is 2.6
billion years old?
Answer:
2.6 billion years
Explanation:
There are essentially two ways of solving nuclear half-life problems. One way is by applying the half-life formula, which is
A
(
t
)
=
A
0
(
t

⋅
(

- the quantity that remains and has not yet decayed after a time t;
A
0
(
t
)
- the initial quantity of the substance that will decay;
t
1
2
- the half-life of the decaying quantity;
In this case, the rock contains
1/4th
of the orignal amount of potassium-40, which means
A
(
t

will be equal to
A

This means that

.
Therefore,
t

⋅

1.3 = 2.6 billion years
A quicker way to solve this problem is by recognizing that the initial amount of the substance you have is halved with the passing of each half-life, or

.
This means that you'll get

Why would a cancer cell need to induce angiogenesis? 1.53
Answer:
Why is angiogenesis important in cancer? Angiogenesis plays a critical role in the growth of cancer because solid tumors need a blood supply if they are to grow beyond a few millimeters in size. Tumors can actually cause this blood supply to form by giving off chemical signals that stimulate angiogenesis.

What is the difference between B-cell lymphocytes and T-cell lymphocytes?
B cells regulate blood pH, and T cells regulate body temperature.
B cells are produced in the thymus, and T cells are produced in the bone marrow.
B cells engulf bacteria, and T cells carry bacteria to the lymph nodes.
B cells produce antibodies, and T cells destroy infected cells.
Answer:
B cells and T cells are the white blood cells of the immune system that are responsible for adaptive immune response in an organism. Both the cells are made in the bone marrow.Explanation:
B cells produce antibodies, and T cells destroy infected cells. So, the correct option is D.
What are B cells and T cells?The two primary categories of lymphocytes are T cells and B cells. Antibody molecules made by B cells can attach to and kill invasive viruses and bacteria. T cells are the immune system's first line of defence against foreign invaders. They also create cytokines, that are biological agents that aid in the activation of other immune system components.
T cells can eliminate malignant or contaminated cells. Moreover, they control overall immune response by assisting B cells in eradicating foreign infections. Antibodies are made by B cells. An antibody is a class of protein produced by B lymphocytes, sometimes known as B cells.
Therefore, the correct option is D.

One Act Example
Shakespeare, Clearly: Romeo and Juliet (one-act)
by Jon Jory
adapted from William Shakespeare
Drama
One-act. 30-35 minutes
8-30 actors
In Shakespeare's most well-known tragedy, two young star-crossed lovers’ deaths ultimately reconcile their feuding families. This straightforward adaptation mixing contemporary and classical language emphasizes story and character rather than the poetry. Master director and acclaimed playwright Jon Jory has reimagined the classic tale to serve as an early introduction for younger audiences and actors that allows easy involvement. Inventive yet faithful, this adaptation will inspire actors and audiences alike to revisit Shakespeare’s original texts. Gender-neutral casting is encouraged and doubling is possible. Simple stage allows for a fluid and forward moving production.
Procedure:
ONE ACT STRUCTURE
Set the Scene.
Introduce the character goal(s)
Introduce an obstacle to the achievement of the goal(s)
Introduce a disaster (the result of a twist if your story has one)
Let the character(s) react.
Resolve the story.
