Researchers may be able to induce adult cells to behave like ______, an important advance in stem cell therapy.
ANEK [815]

Researchers may be able to induce adult cells to behave like embryonic stem cells an important advance in stem cell therapy.

Embryonic stem cells :

Embryonic stem cells  are found in the inner cell mass of the human blastocyst, an early stage of the developing embryo lasting from the 4th to 7th day after fertilization. In normal embryonic development, they disappear after the 7th day, and begin to form the three embryonic tissue layers.

How embryonic stem cells are obtained?

Stem cells are now being collected from human embryos. In most cases, the embryos that are used have been aborted or left over from in vitro fertilization procedures. Although not technically feasible at this time, researchers expect that it is possible to clone stem cells from a patient's own somatic cells.

Cell therapy :

Cellular therapy (CT) is the transplantation of human cells to replace or repair damaged tissue and/or cells. With new technologies, innovative products, and limitless imagination, many different types of cells may be used as part of a therapy or treatment for a variety of diseases and conditions.

Discuss four ways a scientist can reduce bias in scientific investigations.​
Anestetic [448]

Answer:

Three ways a scientist can reduce bias include: 1) Sampling a larger pool (assuming the subjects are human) in order to broaden recorded data. 2) Making sure to sample more than one group. This means to not just sample one's friends, etc.

KatRina [158]

Answer: B

Explanation: Researchers have induced differentiating cells to revert to being stem cells. According to Spradling, it has long been known that some specialized, or differentiated, cells in the body can revert to become stem cells to regenerate tissue under particular conditions

emily wants to know how green, blue and red color light affects plant growth compared to natural light. (Hint: what light affect
MArishka [77]

Red and blue colored lights are most effective for plant growth.

Plant Growth is the dependent variable and light color is the independent variable. The rest are control variables.

A Control variable is the part of the experiment that we keep the same throughout all of the test subjects. An independent variable does not depend on other variables and a dependent variable does.

Allow me to explain. When we perform an experiment, many factors that can change the results, For this reason, it is common practice to keep many of them the same for all test subjects (In this case for all of the plants). This way we know that if changes are measured, they were not caused by these variables. These are what we call control variables.

An independent variable does not depend on other variables to remain the same. For example, the species of plant would be an independent variable, given that a plant cannot change its species because of other factors.

A dependent variable does change according to other variables and is often what we try to measure. For this example given, the dependent variable is how much the plant will grow with each colored light.

Knowing that plants rely on light to produce the energy needed to grow, we can <u>hypothesize</u> that applying different colors of light will have an effect on plant growth. To test this, we can create an experiment where we use:

  • Soil
  • amount of water
  • amount of light
  • species of plant
  • length of experiment

As control variables.

One group of plants will have blue light, another green, and another red. We can identify the color of light as an independent variable.

Since what we seek to measure is plant growth, we identify this as our dependent variable and measure it for each plant after a set amount of time, to compare results.

With this, you can confidently identify the control, dependent, and independent variables and how to use them in your experiment.
