Korvikt [17]3 years ago

Answer:

B.

Explanation:

The rise in the acids levels of the sea water is caused by the dissolve of CO2 in sea water which lowers the pH.The resultant unstable  compound(weak acid) formed is H2CO3.The latter dissociates to for HCO3 + CO3- These  reversible products are the buffers in the seawater that resists the fluctuation in the pH. The carbonate ions reacts with the high concentrations of  Ca + in the sea water, to form  the exoskeleton s of some  fauna.e.g.,Mussels.

  An organism takes care of its young and produces few offspring. What type of organism is this? 
erma4kov [3.2K]

Answer:

K-strategists

Explanation:

Reproductive pattern in organisms can be typically categorised into two:

1. K- Strategy

2. R- Strategy

K-strategists are organisms that lives in very stable environments and gives birth to fewer organisms. Most of these organisms reproduce close the carrying capacity of their habitat. They offer support and protection to their progeny to the points where they become indepedent. The mortality rate is very low in such organisms and so is the birth rate too.

R-strategists are organisms whose main aim is to populate and dominate an environment. They reproduce exponentially and offers no life support to their progeny in their early developmental stage. They often occupy unstable and highly unpredictable environments. Most R organisms have a very low and short life expectancy. Since they produce more offspring and they live under adverse environments, mortality rate is high.

Examples of K-strategists are elephants and man

Examples of R-stategists are grasses and microbes.

________ is a fluid similar to cerebrospinal fluid that fills the space between the bony labyrinth and the membranous labyrinth.
tatiyna

Answer:

<u>Perilymph</u> is a fluid similar to cerebrospinal fluid that fills the space between the bony labyrinth and the membranous labyrinth.

Explanation:

The inner ear consists of the bony labyrinth and the membranous labyrinth, it is filled of endophilia and surrounded by perinfilia (the bony labyrinth surrounds the membranous, between both there is a space occupied by the perilymph). Perilymph is an albuminous fluid that has an ionic composition similar to the extracellular environment, it bathes the tympanic and vestibular ramps, fully occupying the bony cavities of the inner ear, bathing the membranous parts located inside these cavities.
