strong cord of fibrous connective tissue extends from the muscle to the bone
Strong cord of fibrous connective tissue extends from the muscle to the bone is Tendon.
The ligament is the first of the fibrous connective tissues. A kind of fibrous connective tissue called a ligament joins two bones together. The bones are held together by ligaments because they are strong enough to do so and flexible enough to let the bones move around so the body can move. A tendon is a rope-like thread of robust, elastic tissue. Your muscles and bones are joined by tendon tissue. Tendons provide limb movement. By absorbing part of the stress your muscles experience when you run, jump, or do other activities, they also assist in preventing muscular damage.There are many tendons in your body.

in step 6 of the citric acid cycle when succinate is converted to fumarate, hydrogen atoms are transferred to fad. the ____________ is catalyzed by a dehydrogenase enzyme.
Succinate is converted to fumarate in the sixth step, which involves a dehydrogenation because two protons are removed.
Because FAD is a coenzyme that is covalently bound to the enzyme succinate dehydrogenase, the notation E-FAD is commonly used.
When succinate is converted to fumarate, two protons are released, which are taken up by FAD and converted into FADH2. This reaction is catalyzed by succinate dehydrogenase.
The conversion of succinyl-CoA to succinate produces the cycle's only high-energy phosphate bond. This is an example of substrate-level phosphorylation.
Succinate thiokinase converts succinyl-CoA to succinate while first generating ATP/GTP via substrate-level phosphorylation. Succinate is dehydrogenated by succinate dehydrogenase, which requires FAD and Fe-S proteins to form fumarate.

How the properties of elements follow a repeating pattern in the periodic table?.
The repeating pattern is called periodicity. In the mid-19th century, Russian chemist Dmitry Mendeleev noticed repeating patterns in the chemical properties of elements. Mendeleev arranged the elements in order of increasing atomic mass to form something similar to the modern periodic table.
If you arrange the elements in descending order of atomic weight, elements with similar properties will appear repeatedly. - These repeating patterns are regular. That is, they occur at regular intervals. The elements are ordered by atomic number, so elements with similar properties appear in the same column. Therefore, the properties of the elements of the periodic table repeat at regular intervals. This principle is known as the periodic law. A row in the periodic table is called a period.

What is the purpose of emission filter in the fluorescence microscope?
The purpose of the emission filter in a fluorescence microscope is to selectively pass light of a specific wavelength or range of wavelengths that correspond to the fluorescence emitted by the specimen, while blocking other wavelengths of light.
In fluorescence microscopy, the specimen is excited by light of a specific wavelength, which causes certain molecules within the specimen to emit light, or fluoresce, at a different wavelength. This fluorescence is then detected by the microscope. In order to effectively visualize the fluorescence and obtain high-contrast images, it is necessary to use filters that are specifically designed to pass light of the same wavelength as the fluorescence emitted by the specimen, while blocking other wavelengths of light that may be present in the microscope.
The emission filter is typically placed in the light path after the fluorescence has been emitted by the specimen, but before it reaches the objective lens and the eye or camera. This allows the filter to selectively pass only the light of the desired wavelength and block other wavelengths, which improves the contrast and sensitivity of the images.
