Answer:
A species that has no permanent home.
The another are differentiated from the anamniotes by the presence of their terrestrially adapted eggs. These eggs are protected by amniotic membranes. Development of these membranes have provided another with their own aquatic environment needed for development.
The development of amniotic membrane is a characteric of amniotic eggs. These membranes include: chorion' facilitating the exchange of gases between the embryo and the mother; amnion, protection the embryo from injuries and shock and also aiding hydration; allantois, excretion of nitrogenous waste such as urea and uric acid etc and also help in respiration.
Another characteristics is waterproof skin due to the presence of lipids.
Another is the existence of costal rib ventilation of the lungs: enables of loss of CO2 through the lungs rather than buccal pumping as foumd in anamniotes.
Answer:
Answer is explained below;
Explanation:
Mercury is a liquid metal that is released into the environment by both natural processes such as volcanic activity, weathering of rocks, etc and human activities such as waste materials from factories. The mercury that reaches the ocean and other water sources is converted into methylmercury by bacteria. Methylmercury is a neurotoxin that interferes with the nervous system and is easily absorbed by the human body.
The methylmercury is taken up by planktons. Small fishes consume large quantities of plankton. Tilapia is a small, short-lived freshwater fish. The methylmercury level in tilapia is lower than that of other fish. When large, long-living predatory fishes such as tuna, shark, king mackerel, swordfish, etc consume many smaller fish with low mercury levels, this causes accumulation of methylmercury at extremely high levels in their tissues over time i.e., the amount of mercury in such bigger fish biomagnifies.
So large, long-lived predators like swordfish and shark often have the highest methyl mercury levels than a small, short-lived tilapia.
Answer:
A) 6
Explanation:
Complex III of the electron transport chain transfers four protons across the membrane during aerobic respiration, per pair of electrons. In the other hand, complex IV is responsible for transporting two protons (per pair of electrons) across the membrane.
If the given compound injects a pair of electron into complex III, four protons will accumulated due to complex III activity and then two more protons as these electrons move forward to complex IV. This means a total of 6 protons being transported to intermembrane space.
