A Swim Bladder is not present in cartilaginous fishes. Also called a fish maw or gas bladder the swim bladder is a gas-filled bladder that allows many bony fish to control their buoyancy by filling or releasing gas form the bladder. This allows them to change bouyancy without wasting metabolic energy by swimming.
Answer:NADH donates it electron to complex I a higher energy level than other complexes while FADH donates it electron to complex II a lower energy complex.
Explanation:
Both NADH and FADH are shuttle of high energy electrons originally extracted from food into the inner mitochondrial membrane.
NADH donate it electron to a flavoprotein consisting of FMN prosthetic group and an iron-sulphur protein in ETC complex-I. Two electrons and one hydrogen ion are are transferred from NADH to the flavin prosthetic group of the enzyme.
While the electrons from FADH2 enters the ETC (electron transport chain) at the level of co-enzyme Q (complex II). This step does not librate enough energy to act as a proton pump.
So NADH produces 2.5 ATP during the ETC and oxidative phosphorylation because it donates its electron to Complex I, which pump more electrons across the membrane than other complexes.
Answer:
Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust.
Sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification. Erosion and weathering include the effects of wind and rain, which slowly break down large rocks into smaller ones.
Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.

Answer:
The Lungs
Explanation:
Asthma is a lung disease that affects your airways. With asthma, the lining of your airways is constantly hypersensitive, resulting in redness and swelling (inflammation). It's similar to how sunburned skin turns red, irritated, and sensitive. The airways become hypersensitive to things you are exposed to on a daily basis, or asthma "triggers." a trigger could be a common cold, stress, changes in the weather, or environmental factors like dust, chemicals, smoke, or pet dander.
Airway remodeling can occur as a result of poor asthma management. When asthma is untreated or poorly managed, it can lead to airway remodeling, which is a serious condition. The lungs become scarred, asthma medications become less effective, and less air can pass through your airways. It is not necessary to remodel the airways.
Hope this helps and if it does, don't be afraid to give my answer a "Thanks" and maybe a Brainliest if it's correct?
