The calcification rate can be determined using the given graph. It is approximately 18 mmol CaCO₃ per m² per day. Thirty mmol of calcium carbonate divided by 18 mmol CaCO₃ per m² per day is equivalent to 1.67. Therefore, it will take 1.67 days to accumulate 30 mmol of calcium carbonate.
Answer: The correct answer is-
species, genus, family, order, class, phylum, kingdom.
A system of hierarchy is used to classify living organisms, according to which living organisms can be classified into seven major levels that can be listed as follows ( in the order of most specific to generalized) -
species→genus→ family→order→class→phylum→kingdom
For example- Species of human beings can be classified as-
Kingdom→ Animalia
Phylum→ Chordata
Class→ Mammalia
Order→ Primates
Family→ Hominidae
Genus→ <em>Homo </em>
Species<em>→ </em><em>sapiens</em>
Answer: Precipitation

Answer:
Hypothalamus controls the vitals of the body in conjunction with the pituitary gland that secrete the hormones that control the basic vital roles.
Explanation:
Slow reproduction process is a disadvantage of sexual reproduction. So option A is correct.
Sexual reproduction is much slower than asexual form of reproduction and the meiosis process is much longer and complex than mitosis. The process of sexual reproduction depends on the fertilization and zygote formation which are time consuming processes. This longer duration of reproduction process leads to lesser number of individuals in the population. In this case there may be instances of producing only one organism per year and if by chance no offspring is produced for certain number of years can lead to extinction of the species.
