A. Ions can only carry positive charges.
B. An ionized atom has a number of protons that is unequal to the number of electrons.
C. A cation will hold a positive charge if it gains one or more electrons.
D. Losing one or more electrons will turn an atom into an anion.
Answer is B
(took the test C is wrong)
parasitism
B.
amensalism
C.
commensalism
D.
symbiosis
Answer: C: commensalism please give me hearts and stars because the answer is right!!
Explanation:
The relationship between the clown fish and the deadly sea anemone can be classified as commensalism. Though the sea anemone’s tentacles are covered with thousands of nematocysts (tiny, venomous harpoons), the clown fish is protected by a thick coat of mucus and is not harmed by the anemone’s venom. The clown fish is therefore protected from predators and is also able to get leftover food from the anemone's meals. Since the clown fish ultimately benefits from this arrangement and the sea anemone neither benefits nor suffers because of the clown fish, the relationship is commensalistic.
The clown fish and the sea anemone exhibit a mutualistic relationship, where both organisms benefit. However, among the options provided in the question, the most accurate is 'symbiosis', which broadly denotes a close, long-term interaction between different biological species.
The symbiotic relationship between the clown fish and the sea anemone is referred to as mutualism. This term, which is missing from the options, indicates a relationship in which both organisms benefit. The clown fish is protected from predators and has access to food remnants, whereas the sea anemone gets cleaned by the clown fish, which removes parasites and debris. Among the options provided, the closest would be symbiosis (option D), as it describes a close, long-term interaction between different biological species, which can include mutualism, commensalism, and parasitism.

Answer:
C.) Alien thickness is mainly affected by temperature. The greater thickness at lower temperatures may be used as a way to stay warmer in colder weather.

Environmental systems.
Answer: The correct answer for the blank is-
Investments and government expenses.
Gross domestic product (GDP) is the total goods and services value, which is produced within the boundary of a country during a particular year.
GDP is measured by expenditure method, which includes investment, government expenditure, net exports (Exports-Imports), and consumption.
Thus, investments and government expenses is the right answer for the blanks.
