Answer:
This question is asking to identify the variable in the experimental statement.
The eye chart is the CONTROL VARIABLE
Explanation:
An experiment consists of several variables to look out for in order to achieve any significant result. These variables are independent variables, dependent variables and control variables. Although independent and dependent variables are the major experimental variables, but control variables are also important.
A control variable is the variable that remains constant or unchanged throughout the experiment. Any change to the control variable will affect the dependent and independent variables. In this question, the eye chart is the CONTROL VARIABLE because it remains constant or unchanged. The same eye chart is used for the experiment.
N.B: The distance to the eye chart is the independent variable while the number of letters visible on the line is the dependent variable. Hence, changing the eye chart (control variable) will affect the distance and the number of letters visible.

What type of graph is used to compare data? Group of answer choices bar graph scatter plot line graph pie chart
Answer: Scatter plot
Explanation: They compare variables in a data set, and this will help determine their relationship. Scatter plots indicate that if high and low variables on the graph coincide, there is a high possibility of correlation. This points normally fall along a line, which can either be a positive correlation or a negative correlation.

label the parts of a DNA molecule
The label A in the given image is pentose sugar, B is phosphate group, C is phosphate group, D is cytosine, E is adenine, and F is a nucleotide.
What is DNA?Deoxyribonucleic acid is a polymer made up of two polynucleotide chains that tangle into one another to form a double helix that contains genetic instructions for the development, operating, growth, and procreation of all lifeforms and viruses. Nucleic acids include DNA and ribonucleic acid.
Nucleotides are strung together in 2 long strands to form a spiral known as a double helix.
The framework of the double helices is similar to that of a ladder, with the base pairs forming the rungs and the sugar and phosphate molecules forming the ladder's vertical sidepieces.
Thus, the label A is pentose sugar, B is phosphate group, C is phosphate group, D is cytosine, E is adenine, and F is a nucleotide.

what is a non-native species?
Answer:
on-native species can become such a common part of an environment, culture, and even diet that little thought is given to their geographic origin. For example, soybeans, kiwi fruit, wheat, honey bees, and all livestock except the American bison and the turkey are non-native species to North America.

What causes amino acids to fold in different patterns to form different looking structures?
Answer:
Hydrogen bonding
Explanation:
Hydrogen bonding causes folding in different patterns of amino acids. This folding is responsible for the formation of different structures of proteins. This folding also helps in producing the secondary structure of protein. This hydrogen bond is present between amino groups and carboxyl groups which helps them in folding their structure in different patterns.

he discipline of microbiology is intimately associated with biochemistry and genetics, because cells are both biochemical catalysts and genetic coding devices. The discipline of microbiology is intimately associated with biochemistry and genetics, because cells are both biochemical catalysts and genetic coding devices. True False
Answer:
True
Explanation:
The discipline of microbiology has to do with the study of microorganisms - tiny organisms that cannot be seen with the ordinary eyes except with the microscope.
Within the cells of microorganisms just as in every other cell, various biochemical processes take place in order to ensure the continued viability of the cells. Genetic information are also passed on from parent to daughter cells during the process of reproduction or cell division.
Hence, the field of microbiology is associated with both biochemistry and genetics.

Which variable is dependent and which is independent? Plants receiving 50 ml of water will grow taller than plants receiving 20 ml of water to
Answer:
Dependent variable: Plant growth
Independent variable: Water
Explanation:
The Independent variable in an experiment is defined as the variable which can be changed or controlled to measure its effect on the dependent variable and change in dependent variable depends on the independent variable.
In the given example quantity of water is an independent variable and plant growth is a dependent variable because quantity of water can be controlled that influences plant growth.
Hence, the correct answer is:
Dependent variable: Plant growth
Independent variable: Water

2. How might you model the relationship between a tomato plant and the hornworm caterpillar?
Identify the components of the model, including inputs and outputs
Answer:
Parasitism is the relationship between tomato plant and hornworm.
Explanation:
The relationship between a tomato plant and the hornworm caterpillar is parasitism because parasitism is a type of symbiotic relationship in which one organism get benefits from other and the other get harmed. We know that hornworm caterpillar feed on leaves and destroy the tomato crop. So it gets nutrients from tomato plant and the tomato plant is destroyed. The input of this system is the vegetative part of tomato plant which can be eaten while the output is the conversion of hornworm caterpillar into a moth.

What is the cephalic phase? Group of answer choices earliest phase of digestion when the brain prepares the body in anticipation of food phase when the semidigested food leaves the stomach and slowly enters the small intestine phase when the majority of absorption occurs, primarily occurring in the small intestine final phase of digestion when the large intestine and rectum prepare the undigested components of food for elimination
Answer:
earliest phase of digestion in which the brain prepares the body in anticipation of food
Explanation:
The cephalic phase is the phase that occurs in the process of gastric secretion. The phase witnesses its initiation when the thought, smell, taste and sight of the food lingers in the mind before its consumption. The nerves sends the signals of the food from the cerebral cortex of the brain. Before the food is consumed or entered in the body, the cephalic phase takes place.
Make an inference about what happens to the matter and energy during the formation and breakdown of a complex carbohydrate molecules? When is energy stored or released?
Answer:
The formation or construction of (larger) molecules from smaller chemical units is known as anabolism. Anabolic reactions are energy consuming or endogernic reactions and are the aspect of metabolism that involve building or constructing. For example in photosynthesis reaction, plant combine smaller molecules of carbon dioxide and water, with the absorption of energy from the Sun's to form sugar, as follows;
6CO₂ (g) + 6H₂O (l) [tex]\overset{Energy \ from \ the \ Sun}{\rightarrow}[/tex] C₆H₁₂O₆ (s) + 6O₂ (g)
In the (reverse) process of catabolism, energy is obtained (released) from the breakdown of larger and more complex carbohydrate molecule, which may be through aerobic (involving oxygen) with the release of energy (in the form of ATP)
The cathabolic decomposition of one gram of carbohydrate can yield 4 kcal of energy
C₆H₁₂O₆ → 6CO₂ (g) + 6H₂O (l) + energy
Therefore;
Energy is consumed during building up or formation of larger carbohydrate molecules from smaller ones and
Energy is released when such large carbohydrate molecules are decomposed (broken down) into smaller molecular units
Explanation:
What's the answer for this question?
Answer:
The answer is A.
