Answer:

The resulting compound has low and melting and boiling points.

Explanation:

Metallic bond: It is the type of bond (chemical) that hold the atoms of metal together, it forms when the electrostatic attractive force present between conduction electron and fixed positive charge metal atoms. So, metal atoms have high melting and boiling point. This means that they take lot of energy to overcome these Forces (electrostatic) during melting and boiling time.

It also describes as the sharing of free electrons between the structure of positively charged ions.

<u>Answer:</u>

Carbon is found in hydrosphere in the form of dissolved carbon in ocean and sea water during the gas exchange process.

  • During this gas exchange process, the carbon is dissolved in the ocean water which is later utilized by marine plants to conduct photosynthesis.

In a particular species of frogs, black spots are a dominant trait and their absence is a recessive trait. In a population of fr
swat32

The correct answer is optionD 134/200.

The frequency of the dominant allele can be calculated by the summation of the frequency of the homozygous individual frequency that has  dominant allele  and half of the heterozygous individuals, as half of the heterozygotes have dominant allele.

The frequency is no of individual of desired trait divided by total number of individual.

The calculation is shown below:frequency of dominant allele=frequency of dominant individual+\frac{1}{2} frequency of heterozygotes\\frequency of dominant allele=\frac{50}{100} +\frac{1}{2} (\frac{34}{100} )\\frequency of dominant allele=\frac{50}{100} +\frac{34}{200} \\frequency of dominant allele=\frac{2(50)+34}{200}\\ frequency of dominant allele=\frac{134}{200}
