Compare the structures of viruses and cells.
Answer:
Cells have a double stranded DNA molecule and many strands of single stranded RNA as the copies. Viruses, however, can have double stranded DNA, single stranded DNA, double stranded RNA, or single stranded RNA. They convert RNA to DNA and then back to RNA to make proteins, which does not happen inside cells.

Which of the following refers to the just-noticeable difference between two stimuli?
A) Absolute threshold
B) Sensation
C) Perception
D) Difference threshold
E) Subliminal stimulus
Difference threshold refers to the just-noticeable difference between two stimuli (Option D). This difference represents the minimum level of stimulation that can be detected by an individual at least half the time.
An absolute threshold can be defined as the lowest level of a stimulus which can be detected by a person at least half the time.
In psychology, an absolute threshold is defined as the minimal amount of energy required to achieve the stimulation of the sensory receptors.
Stimuli from the surrounding environment include touch, light, sound, etc.

How to make bacteria as a treatment for sewage waste
Answer: Bacteria break down organic material in wastewater and form the floc that settles and separates solids from liquids. Controlling F/M ratio–a vital component to creating a favorable environment for wastewater bacteria–can be accomplished through the use of bioremediation products. Bacteria account for 95% of the microorganisms in wastewater. They are single-celled microorganisms that are classified based on their response to oxygen.
Aerobic bacteria use oxygen, which is added mechanically, to break down wastewater contaminants, converting it into energy. Bacteria use this energy to grow and reproduce. Anaerobic bacteria obtain oxygen from their food source. As anaerobic bacteria break down sludge, they produce methane gas. This methane gas can be used as an alternative energy source, called biogas, to fuel the wastewater treatment process. Anaerobic bacteria can also be used to lower the amount of phosphorus in the effluent. Although they prefer oxygen, facultative bacteria can switch between aerobic and anaerobic forms in response to their environment.

What type of diffusion is aided with a transport protein?
a. Osmosis
b. Permeated diffusion
c. Facilitated diffusion
d. Osmotic diffusion
Facilitated diffusion is the diffusion of solutes through transport proteins in the plasma membrane. Facilitated diffusion is a type of passive transport. Even though facilitated diffusion involves transport proteins, it is still passive transport because the solute is moving down the concentration gradient.

Lillian parents are farmers. There are two types of fertilizers on the market. Both brands claim to grow carrots fastest. Plan and design an experiment to help Lillian's parents. Identify the independent, dependent and a control variable
The experiment to help Lillian's parents will consist of planting various carrots using both kinds of fertilizers, and maintaining a constant carrot type, amount of light, and amount of water throughout each plant.
In order to perform an accurate experiment, we need to identify three kinds of variables:
Independent variableDependent variableControl variableIn an experiment, the Independent variable is one whose value does not depend on the others. What this means is that this variable will not react to changes that occur in others. In this experiment, the independent variable is the fertilizer, given that it is not affected by the species of carrot, type of soil, or any other variable present.
The dependent variable in an experiment is just the opposite, it is, as the name implies, a variable whose value depends on the other variables present. In an experiment, this variable represents the data that we seek to measure. For this experiment, the dependent variable is the growth rate of the carrots because it is affected by the amount of water, light, and type of fertilizer we use, as well as being what we wish to measure.
Finally, the last variable we must identify is that of the control variable, also known as the constant or standardized variable. This variable is of vital importance for the accuracy of any experiment. This variable corresponds to those factors which we maintain constant through each trial in the experiment, for the example above, it is the amount of water and light, as well as the type of carrot, Lillian's parents will use.

Wjy is the increase in atmospheric carbon dioxide dangerous?
Answer:
The gas inhibits the escape of heat from Earth’s
Explanation:
This is the main cause of global warming. They cause climate change by trapping heat and they also contribute to respiratory disease from smog and air pollution. Extreme weather, food supply disruptions, and increased wildfires are other effects of climate change caused by greenhouse gases.
The earth temperature depends upon the balance between the incoming radiation from the sunlight and the energy that is reflected back to space. Carbon dioxide absorbs the heat sent to earth by the sun, it acts as an insulator of the earth and helps to keep the atmosphere warm and make suitable for life process.
But, when the concentration of carbon dioxide in the atmosphere is increased, it means more and more increase in the temperature of the planet and cause global warming and make the life difficult on the planet. As a result of that whole life on the earth would be in danger.
Answer:
If you increase carbon dioxide, the temperature can go up causing our earth to have global warming problems.
