Theory is ur answer lol ororoor
The answer is d. you will recognize that heart tissue is tightly compacted and striated to allow the heart to beat, etc....
The pneumatic bones are important to birds for respiration. They are hollow bones which are connected to the bird's respiratory system and are important for birds to be able to breath. Examples of pneumatic bones are the skull, humerus, clavicle, keel (sternum), pelvic girdle, and the lumbar and sacral vertebrae.
1-refraction
2-transmission
3-reflection
4-diffraction
<u>Explanation:</u>
Refraction is the bending of a wave when it enters a medium where its speed is different.Refraction is responsible for image formation by lenses and the eye.
Transmission of light is the moving of electromagnetic waves through a material. This transmission can be reduced, or stopped, when light is reflected off the surface or absorbed by the molecules in the material.
Reflection is when light bounces off an object.Light is reflected when there is a mismatch between materials through which the light is travelling.
Diffraction is the slight bending of light. The amount of bending depends on the relative size of the wavelength of light to the size of the opening.
Answer:
Explanation:
The production of ATPs for skeletal muscle contraction depends on the conditions that the muscles are exposed to.
In presence of abundant oxygen, to the cells Aerobic respiration-cellular respiration is the most ideal. 32 ATPs and 4 C02 are produced as by-products during the process as by products majorly two C02 from each of the 2 acetyl Co A that enters the kerb's cycle.
Likewise direct phosphoryaltion of ADP to ATP gives 32.0 kj/mol of heat liberated but no C02 was produced. This takes place during chemiosmosis. with 28ATPs produced.
In absence of oxygen, anaerobic respiration of skeletal muscles produced ATPs from glycolysis, heat and 2C<u>02 as products, but not as by-product</u>.Through alcoholic fermentation pathway.
Therefore ,the correct answer is Aerobic respiration, because it gives out C02 which is a by-product, released out of the body as waste from the lungs,and not use up in the body.
