Metallic bonds do have shiny surfaces (hence, the name metallic).

Metallic bonds are good conductors of electricity.

Metallic bonds cannot be dissolved in water.

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.

Describe at least two ways that carbon can get from the atmosphere to Hydrophere

notsponge [240]

<u>Answer:</u>

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

<u>Explanation:</u>

Carbon cycle is the process of transformation of carbon in different forms. From atmosphere, the carbon gets into hydrosphere during the gas exchange processes.

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

There is a continuous transformation of carbon from lands, plants to atmosphere and from atmosphere to hydrosphere.

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: $frequency of dominant allele=frequency of dominant individual+\frac{1}{2} frequency of heterozygotes\\frequency of dominant allele=\frac{50}{100} +\frac{1}{2} (\frac{34}{100} )\\frequency of dominant allele=\frac{50}{100} +\frac{34}{200} \\frequency of dominant allele=\frac{2(50)+34}{200}\\ frequency of dominant allele=\frac{134}{200}$
