___________ promises to solve many medical problems with new drugs and procedures that will contribute to the spiraling costs of

antoniya [11.8K]

Answer:

Biotechnology.

Explanation:

Biotechnology may be defined as the field of biology that uses the living organisms to make product by using molecular techniques. Biotechnology involves the different field like biomedical engineering, biomanufacturing and bioengineering.

The genetic system of the living organism can be modified to obtain the desired products. Artificial insulin is prepared by the application of biotechnology. The new drugs in the market and desired trait in the living organism can be prepared by the biotechnology field.

Thus, the correct answer is biotechnology.

When the archer releases the arrow, the [blank] energy in the bow string transforms into [blank] energy for the arrow.

Kobotan [32]

Answer:

potential energy, kinetic energy

Explanation:

potential energy is the energy held by an object because of its position. kinetic energy is energy in motion. when the bow is being drawn back it has potential energy because of its position and that at any moment it can be converted into kinetic energy.

How does removing trees affect nitrogen cycling in a forest ecosystem? A. After clearcutting, more soil nitrogen was exported vi

mina [271]

Answer:

B. After clearcutting, plant uptake stopped and nitrogen accumulated in the soil.

Explanation: Clear cutting leaves the soil bare and allows for direct penetration of sunlight this increases the soil temperature which favors the activity of soil microrganism. This microrganism activity increase the production of ammonium and nitrate hence the increase in soil Nitrogen level. Clearcutting then allows for accumulation of Nitrogen produce due to removal of plant or forest tree that could use up the Nitrogen produced.

1. What are the independent and dependent variables in each of the experiments?

Dafna1 [17]

The independent variables are temperature, airflow, and light and the dependent variable in each of the experiments is evaporation.
The schematic representation in the diagram helps in the understanding of the setup for the experiments.
The level of temperature, the rate of airflow, and the intensity of light must be controlled in the experiments.
A person will not be confident in experiment 3 results as the temperature is the independent variable that alters the results of evaporation.

<h3>What are the four foremost factors of a managed test?</h3>

When possible, scientists take a look at their hypotheses through the use of managed experiments. A managed test is a systematic take look at executed below-managed conditions, which means that simply one (or a few) elements are modified at a time, even as all others are saved consistently. We'll appear carefully at managed experiments within side the subsequent section.

In the three experiments, the dependent variable is evaporation, as it changes with the change in another variable.

The independent variable in experiment 1 is temperature, experiment 2 is airflow, and experiment 3 is light.

The experiment can be understood better with the representation of the schematic that shows the setup to analyze how the experiment was performed. Therefore the diagram must add the schematic of the experiment.

The controlled items in the experiment are the variables that are set at the particular unit to form the result. the controlled item in experiment 1 is temperature, experiment 2 is airflow from the fan, and experiment 3 is the intensity of light.

The result of experiment 3 is based on the dependence on the intensity of light keeping temperature constant and controlled. If the temperature is not controlled in the experiment then it may lead to an alteration in the results as it depends on both light and temperature.

The flow chart for the increase in pressure affecting the evaporation is given in the image attached.
