Tuberculosis (TB) is a bacterial infection that has both an active phase and a latent phase. In the active phase, TB affects the

lungs. In the latent phase, TB spreads to other organs in the body. TB can be treated with antibiotics; however, the course of treatment is long. Some strains of TB are resistant to many antibiotics, making them very difficult to cure.

4. The light-independent reaction uses the energy from _________ to produce _________.
luda_lava [24]

Answer:

The light- independent reaction uses the energy from <u>NADPH and ATP</u> to produce <u>Sugar</u>.

Explanation:

The end product of light- independent reaction is sugar (glucose) which is made from carbon dioxide.  The energy for these comes from the end results of light- dependent reactions .

This includes NADPH and ATP. This process is termed as the Calvin Cycle.

Steps of the Calvin Cycle include:

1. The formationof a six carbon sugar , Phosphoglycerate, by combination of a five carbon sugar, Ribulose biphosphate (RuBP) and Carbon dioxide.

2. The formation of two molecules of Triose Phosphate by reducing Phosphoglycerate using hydrogen atoms of the light- dependent reactions. This reaction uses ATP.

3. ATP is also used  to convert some of the Triose Phosphate back to RuBP.

4. GLUCOSE is produced using the rest Triose Phosphate.

How does an ultrasound produce an image of a fetus in the mother’s uterus?
Alisiya [41]
An ultrasound can produce the image of a fetus by using waves that are labeled as "ultrasound waves" or in ultrasonic frequency.

This may seem like an odd concept but you should note that everything we see and hear is made up of waves, like light and sound, that are at different frequencies.

The reason why there are different color lights are because there are different type of frequencies.  Some frequencies, such as ultrasonic, we can not see with our human eye.<span />

Different plant species require different amounts of direct sunlight in order to flower. A student designed an experiment to det
Gnoma [55]

Answer:

Independent variable: LENGTH OF EXPOSURE TO DIRECT SUNLIGHT

Dependent variable: PRODUCTION OF FLOWERS

Control group: THE GROUP OF PLANT THAT WASN'T EXPOSED TO SUNLIGHT i.e. 0 hours

Experimental group: THE GROUP OF PLANTS THAT WERE EXPOSED TO SUNLIGHT

Constant: THE SAME PLANT SPECIES

Explanation:

Independent variable is the variable that the experimenter changes or manipulates in an experiment. In this experiment, the experimenter exposes the specific plant species to sunlight at different length of time, hence, the LENGTH OF EXPOSURE TO DIRECT SUNLIGHT is the independent variable.

Dependent variable is the variable which is measured in an experiment. In this experiment, the measured/dependent variable is the PRODUCTION RATE OF FLOWERS by the plant species.

Control group is the group in an experiment that does not receive the variable being tested. In this experience, the control group is THE GROUP OF PLANT THAT WASN'T EXPOSED TO SUNLIGHT i.e. 0 hours

Experimental group is the group of am experiment that is exposed to the experimental treatment (sunlight). In this case, the experimental group is THE GROUP OF PLANTS THAT WERE EXPOSED TO SUNLIGHT.

Constants are variables of an experiment that must be kept unchanged for all groups throughout the experiment in order not to affect the experiment's outcome. In this experiment, the constant is THE SAME PLANT SPECIES used,
