Limestone formations in caves are considered what kind of weathering
madreJ [45]

Answer:

Chemical weathering

Explanation:

Caves are formed by the dissolution of limestone. Rainwater picks up carbon dioxide from the air and as it percolates through the soil, which turns into a weak acid. This slowly dissolves out the limestone along the joints, bedding planes and fractures, some of which become enlarged enough to form caves.

Chemical weathering involves the decomposition of rocks due to chemical reactions between minerals such as calcite with water and gases in the atmosphere (e.g. carbon dioxide and sulphur dioxide). The solution of soluble minerals is particularly important in limestone landscapes.

Solutional caves or karst caves are the most frequently occurring caves. Such caves form in rock that is soluble; most occur in limestone, but they can also form in other rocks including chalk, dolomite, marble, salt, and gypsum.

Essentially, water reacts with carbon-dioxide to form carbonic acid. It then seeps slowly through the roof of the cave, depositing calcium carbonate, which hardens and builds up over time to form a stalactite.

If there are probability of 50% of producing male gamete then what would be the probability of producing transgender. When fathe
Vaselesa [24]

The probability of producing a transgender = None ( D ) when the father is gay

The probability of producing male gamete is not affected by the sexual orientation of the Father because the production of the male gamete is carried by the spermatogonia found in the testes of a male. and every male specie regardless of your sexual orientation have testicles where the spermatogonia undergoes mitotic divisions to produce the male gametes.

Hence the probability of producing a transgender given that the father is gay is non-existent i.e.0%

vovangra [49]

Answer:

Change occur in the genetic makeup.

Explanation:

Brian means that the change occur in the genetic makeup of the mitochondrial DNA that change the structure as well as the function ability of mitochondria which is responsible for the generation of energy for the cell. The mitochondrial DNA are passed from mother to offspring through the egg cell. He signify mitochondrial DNA because the change occur only in the mitochondrial DNA not in the whole organism's DNA.
