Answer:

The correct answer will be-Stapes

Explanation:

The tympanic membrane is the membrane present in the outer structure of the ear which vibrates when it receives the sound vibrations from the outer world.

Inner to the tympanic brain lies three bones called incus, malleus and stapes. These bones are attached in a chain-like fashion convert the vibrations of the membrane to the mechanical vibrations of these bones.

Since the bone which fills the oval window and transfers the vibration to the inner ear is called stapes.

Thus, stapes is the correct answer.

Dependent variable: Taste of the salsa

Explanation:

The aim of every experiment is to solve a problem or answer a scientific question about an observed problem. The first step in the scientific method is to ask a question. In this experiment in which Martha is trying to check which variety of tomato is best for making her salsa taste great, the problem question is: Which tomato variety will taste better in making salsa?

- Independent variable is the variable in an experiment that is changed or manipulated. In this experiment, the independent variable is the VARIETY OF THE TOMATO.

- Dependent variable is the variable that is measured in an experiment or in other words, the dependent variable responds to changes to the independent variable. In this case, the dependent variable is the TASTE OF THE SALSA.

Corn seed has more non-metabolicallyactive storage material

jekas [21]

Answer: Respiration rate in corn seed will become high as compared to barley seed.

Explanation:

After a seed get separated from the plant, it undergoes through a resting period called as dormancy. The seed metabolizes the available stored form of energy reserve very slowly. The metabolic source is a stored form of potential energy in the seed. The cellular respiration is a process in which the available food is oxidized to produce energy. The seed in the dormant stage also performs cellular respiration to stay alive but at low rate. The respiration rate will be more in seeds that exhibit non-metabolic active storage material like fat or protein as the seed will require more oxygen for it's break down.

The corn seed exhibit the non-metabolically active storage material thus the rate of respiration will be high as compared to barley.
