The volume (V) of a cylinder can be determined by using the formula
V = ar?h,
where r = the radius of the base, and h = the height of the cylinder. What is the result
of solving this equation for r?
Answer:
Explanation:
To solve for r, simply means to isolate the variable:
[tex]V = pi*r^2*h\\[/tex]
The inverse of multiplication is division, so divide both sides by pi and h
[tex]\frac{V}{pi*h} = r^2[/tex]
[tex]r = \sqrt\frac{V}{pi*h}[/tex]

(ii) Describe an experiment he could carry out to show that auxin causes bending of a
shoot.
Answer:
Illumination results auxin moving to the dark side of stem tips. As this auxin diffuses down the dark side of the stem, the cells respond by enlarging. This causes the plant to bend toward the light.

Describe four assump-tions traditionally made in economics that canhave a negative effect on the environment.
Answer:
The four types of economic assumptions that can negatively affect the environment are:
1. Natural resources and human resources are infinite
2. It grants an event in the future less value than one in the present; short-term costs and benefits are granted more importance than long-term costs and benefits.
3. All costs and benefits associated with an exchange of goods or services are borne by individuals engaging directly in the transaction (buyer and seller alone).
4. Economic growth is required to keep employment high and maintain social order.

identify the part of a rib that articulates in the demi-facets of the thoracic vertebra.
Answer:
The capitulum of a rib sits between and articulates with two successive centra, for which most thoracic vertebrae possess costal demifacets. These are anteriorly and posteriorly paired facets, so that a vertebra typically has four demifacets.
Explanation:
what determines the specificity of a receptor protein?
Answer:
A working hypothesis is that signaling efficiency/specificity is determined in part by proteins found in the receptor's microenvironment, which together with R, G, and E contribute to the formation of a signal transduction complex at the cytoplasmic face of the receptor.

Why do lysosomes keep their digestive
enzymes in membranous sacs?
A. because the membranous sacs can sense when the cell is about
to be attacked
B. because the membranous sacs keep the digestive enzymes
from destroying the cell
C. because the membranous sacs act as tails that help the
lysosomes move faster
D. because the membranous sacs act as factories helping the
digestive enzymes make proteins
The correct answer is option B. because the membranous sacs keep the digestive enzymes from destroying the cell.
What is the purpose of the membrane surrounding the lysosome?The membrane surrounding the lysosome is vital to ensure these enzymes do not leak out into the cytoplasm and damage the cell from within. In order to maintain the acidic pH of the lysosome, protons are actively transported into the organelle across the lysosomal membrane.
What part of the cell is a membranous sac?
A vesicle is a small, membrane-bound sac that transports substances in cells. The ER moves proteins and other substances within eukaryotic cells. Vesicles that contain newly made proteins move through the cytoplasm from the ER to an organelle called the Golgi apparatus.

b cells are white blood cells that work by ___________________, whereas t cells attacks foreign invaders __________________.
Answer:
They flow through your bloodstream to fight viruses, bacteria, and other foreign invaders that threaten your health. When your body is in distress and a particular area is under attack, white blood cells rush in to help destroy the harmful substance and prevent illness. White blood cells are made in the bone marrow.
Explanation: cells are white blood cells that work by bacteria, viruses, parasites and fungi.
How are a hypothesis and a theory similar?
Answer:
A hypothesis is either a suggested explanation for an observable phenomenon, or a reasoned prediction of a possible causal correlation among multiple phenomena. In science, a theory is a tested, well-substantiated, unifying explanation for a set of verified, proven factors.
