Anything under a ph of 7 is considered acidic (considering ph7 is the universal solvent/water) anything above 7 would be alkaline . But since you’re asking for something with a ph of 4 it could be tomato juice
The answer is Filarial parasites. They belong to the group of roundworms of the Filarioidea type. An example of a filarial worm is the Wuchereria bancrofti. These organisms cause lympathic filariasis (LF) which is characterized by edema. They are spread by the mosquito vector.
Answer;
ATP is needed to relax the muscles;
Muscles require more energy even if they are not very active in the moment because ATP or energy is needed for their relaxation.
Explanation;
Relaxation of muscles takes place when the stimulation of nerves stops. Calcium is then taken back into the sarcoplasmic reticulum breaking the link between actin and myosin. Actin and myosin return to their unbound state causing the muscle to relax. ATP is involved in displacing actin from myosin head. Therefore; ATP is required for muscle relaxation.
Answer:
<u><em>All of the above.</em></u>
Explanation:
1. Their watertight skin minimizes moistures loss: <em>Reptiles have a reputation that they are “slimy” when we touch and hold them; however, they have dry skin, which has even fewer glands than mammals or amphibians. The main special feature of their skin is that the epidermis is heavily keratinized with a layer, which also prevents water loss.</em>
2. Amphibians must lay eggs in water or in moist soil to reduce moisture loss: <em>Because amphibian eggs don't have an amnion, the eggs would dry out if they were laid on the land, so amphibians lay their eggs in water.</em>
3. Reptile egg shells are harder than amphibians' eggs: <em>Reptile eggs are coated with a leathery or brittle coating, and the animals that hatch from them are miniature versions of the full-sized animal parent. In contrast, amphibian eggs are transparent and jelly-like. The animals that hatch from them still must go through metamorphosis.</em>
