The chemical energy that cells use to perform work is primarily derived from breaking the phosphate-phosphate bond in ATP.

The energy is released in the form of ATP during a process known as cellular respiration.

Hope it helped!

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.

An individual that is heterozygous for flower color and for height (PpTt) is test crossed. What is the phenotypic ratio of the o
MrRa [10]

Answer:

9:3:3:1

Explanation:

This type of crossing that involves two characters is referred to as dihybrid crossing. Generally, when there is a dihybrid crossing for heterozygous genes for both parents, the phenotypic ratio is usually 9:3:3:1 as shown in the figure in the attached document below.

Assuming the colour is White (P) and Black (p) and the

Height is Tall (T) and short (t)

The possible phenotypes will be in the ration

9 - White and Tall

3 - White and short

3 - Black and Tall

1 - Black and short

It should be noted that phenotypic ratio (phenotype) describes the outward appearance (what can be see physically) and not the genetic make-up. Thus, where there is a dominant character like P or T, the recessive characters are not considered to have been expressed.

Calculate the average metabolic rate of a 65-kg person who sleeps 8.0h, sits at a desk 6.0h, engages in light activity 6.0h, wat
Anna35 [415]

Calculate the average metabolic rate of a 65-kg person who sleeps 8.0h, sits at a desk 6.0h, engages in light activity 6.0h, watches TV 2.0h, plays tennis 1.5 h, and runs 0.50h daily, If the metabolic rate for sleeping is 70 J/s, for sitting is 115 J/s, for engage in light activity is 230 J/s, for watching TV is 115 J/s, for playing tennis is 460J/s and for running is 1150 J/s.

Answer:

171.8 W

Explanation:

The Average metabolic rate can be deduced by multiplying each entity performed at a some particular hour of time with their corresponding energy, all divided by 24 hours.

Average metabolic rate = \frac{(8.0*70)(6.0*115)(6.0*230)(2.0*115)(1.5*460)(0.5*1150)}{24}

                                        = 171.8 W
