Kim's Dalmatian, Tigger, always eats the same brand of food. Although he does everything else at lighting speed, he is a very slow eater. After watching a TV commercial touting the irresistible taste of Puppy Yums Dog Vittles, Kim decides to conduct an experiment comparing Tigger's regular food (K-9 Crunchy Bits), Puppy Yums Dog Vittles, and a store brand that cost 1/3 as much as the advertised food. Kim gave Tigger the same quantity of each different food, on three successive evenings, and used a stopwatch to determine Tigger's dinner-time munching speed.
Hypothesis:
Predicted Results:
Independent Variable:
Dependent Variable:
Control Variable:
The experiment was intended to show that the dog will eat the tastier food advertised on TV at a faster rate than it eats its regular food.
An experiment must have an independent variable and a dependent variable. The dependent variable is the variable that is being manipulated in the experiment. The responding variable is also called the dependent variable.
In this experiment;
The independent variable is the type of dog foodThe dependent variable is the eating time of the dogThe predicted result is that the dog will eat the advertised Puppy Yums Dog Vittles faster than the other dog foodsThe control variable is the quantity of dog food given to the dog each evening.The hypothesis of the experiment is that the dog will eat the advertised tasty food faster than it eats its regular food.Learn more: https://brainly.com/question/22824409

Tại sao con người chúng ta lại sốt nhiều lần như vậy?
Answer:
Fever is an elevated temperature of the human body that is substantially beyond the normal range. Normal body temperature fluctuates daily from about one degree below 98.6 degrees Fahrenheit to one degree above that number. Lower body temperatures usually occur before dawn; higher temperatures in the afternoon.
Body temperature also varies slightly depending on where on the human body it is measured. Rectal (internal) temperature tends normally to be higher than skin (surface) temperature. Oral and armpit temperatures can approximate actual body temperature and are more convenient to measure.

what type of inheritance do two alleles have if their traits blend together?
Answer:
Explanation:
Codominance is when both dominant traits are expressed, therefore if white was considered dominant and red was also a dominant trait, the petals would have spots of white and red, with no pink. Polygenic inheritance is described by one characteristic influenced by multiple genes, which is not the case in this problem.

Do you think one gene controls human hair color? Explain your answer.
Do you think one gene controls human hair color?
No, this is false. Not only one gene is responsible for the colour of your hair, at least 2 gene pairs control human hair colour. Therefore, this is wrong since each parent contributes multiple hair-colour genes .
Hope this helped you, have a good day bro cya)
Answer:
There are many different phenotypes for hair color among humans. Therefore, multiple genes control hair color.
nucleic acids are assembled in the _____ direction.
Nucleic acids are assembled in the 5' to 3' direction during DNA replication. DNA replication is the process of duplication of DNA molecule.
What are Nucleic acids?Nucleic acids are the biomolecules occurring in the chemical compounds which serve as the primary information-carrying molecules in the cells. Nucleic acids play an important role in directing the process of protein synthesis. The two main classes of nucleic acids include deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Nucleic acids can only be synthesized in vivo in the 5′-to-3′ direction and these can be assembled in the same direction in cell, as the polymerases which assemble various types of new strands generally rely on the energy which is produced through breaking the nucleoside triphosphate bonds to attach these new nucleoside monophosphates to the 3′-hydroxyl (−OH) group, through a phosphodiester bond.

how does the plasma membrane contribute to the structure and function of the cell?
Answer:
The plasma membrane, also called the cell membrane, is the membrane found in all cells that separates the interior of the cell from the outside environment. ... The plasma membrane consists of a lipid bilayer that is semipermeable. The plasma membrane regulates the transport of materials entering and exiting the cell.
A cell is protected by its cell membrane, also known as the plasma membrane. Additionally, it moves hazardous materials out of the cell and carries nutrients into the cell.
What is a cell membrane?All cells' interiors are protected from the outside world by a biological membrane called the cell membrane. A cell is protected by its cell membrane, also known as the plasma membrane. Additionally, it maintains a constant environment inside the cell, and that membrane serves a variety of purposes. One is to move substances out of the cell that are toxic as well as nutrients into the cell.
Glycerophospholipids, molecules made of glycerol, a phosphate group, and two fatty acid chains, are what make up cellular membranes, including plasma membranes and internal membranes.
