Triticate is a crop species resulting from a plant breeder's cross between wheat (Triticum) and rye (Secale). It is produced by doubling chromosomes of the sterile hybrid that results when crossing wheat and rye. This doubling produces what is called a polyloid.
Answer and Explanation:
1. <u>Hypothesis</u>: <em>The more sunflower seeds the students get, the better they will do on a quiz.</em>
2. <u>Dependent Variable</u>: Responding variable refers to the dependant variable, which response depends on any change in the independent variable. A change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. In the exposed example, the dependent variable is the response of each group to sunflowers seeds expressed as their grades on quizzes.
3. <u>Independent Variable</u>: <em>number of sunflower seeds. </em>Manipulated variable refers to all the variables in an experiment that provoke a response in another variable. They are also known as independent variables. The researcher can change these variables to see what changes it implies in an object, process, trait, or anything that depends on them. In the exposed example, the researcher manipulates the number of sunflower seeds promised to each group.
4. <u>Constant Control Group</u>: Group 1, which does not receive any sunflower seeds. The election of a control group is essential in an experiment. Its principal purpose is to allow the discrimination of the results obtained by the treatment in the study, in this case, the provision of sunflower seeds, from the results that might be a consequence of other factors. The control group must be selected from the same population of the treatment group. All groups must be similar in every variable that might influence the results, except for the study treatment
5. <u>Experimental Group</u>: Groups 2 and 3, that received different amounts of seeds.
Q1. Muscles are made of muscle cells that are able to contract. They are only cells in the organisms able to do that. Due to contraction, cells change their shape and length. This enables some organ activity (such as heart, or many other organs that are surrounded by smooth muscles that helps them perform their function) or body movements.
Q2. Striated muscles are called striated because of the series of sarcomeres, basic units of striated muscles. They are made up of long cylindrical fiber and attach to the bones. Contraction of these muscles is voluntary <span>except for the heart muscles</span><span>. During these contractions, the muscle is extended by the action of an antagonist muscle.</span>
A dinner comprised of rice and chicken. Rice is a simple carbohydrate and will build up the ATP in his system to make his run time better and give him energy. Chicken is a long term energy source that will keep him full and his muscles working throughout the marathon.
