Phloem cells are __________. a. dead at maturity and are used to transport water from the roots to the rest of the plant b. dead
at maturity and are used to transport sugars throughout the plant c. alive at maturity and are used to transport water from the roots to the rest of the plant d. alive at maturity and are used to transport sugars throughout the plant
Answer: b. dead at maturity and are used to transport sugars throughout the plant.
Phloem cells are the cells which transport the product of photosynthesis that is food from the leaves to other parts of the plant. A typical phloem consist of sieve cells, phloem fibers, and phloem parenchyma. Sieve cells are elongated and they have minute pores which facilitates the transport of food through these pores. The phloem fibers provides mechanical support to the phloem. Phloem parenchyma cells are responsible for the storage of food. The process by which phloem transport food is called as translocation. Sieve cells are the main type of cells helps in food translocation, in maturity these cells looses their nucleus and ribosomes therefore, they die in maturity.

Explanation:
To find a foreign body a radiology exam has to be done. In this senerio the foreign body was not found. In the CPT® Index, look for X-ray/Nose to Rectum/Foreign Body. The correct code is 76010
All observations and information that scientists perceive and record are called data.
A dependent variable, also known as response variable, defines the treatment/variable that changes in response to the independent variable.
According to the second postulate of the Cell Theory, the cell is the basic structural and functional unit of life.
Cells that perform similar functions are grouped together to form tissues.
An experiment is a controlled setting/test that investigates (proves or disproves) a scientist's hypotheses.
One of the major properties of life is to harvest and convert energy to drive basic cellular processes.
Independent or test variable does not depend on any other factors. It is itself changed to determine its effect on the response variable.The amount of coke is the independent variable.
Homeostasis is defined as an organism's ability to regulate its internal environment in response to fluctuations in the external environment.

Homeostasis is defined as an organism's ability to respond and regulate its internal environment in response to fluctuations in the external environment.
The experimental and control groups differ in the independent variable as only the experimental group receives the variable or treatment.
Quantitative data is quantifiable, numerical data in which the effects of the independent variable on the response variable can be compared through mathematical and statistical tools.
