Answer:

The only mutations that matter to large-scale evolution are those that can be passed on to offspring. These occur in reproductive cells like eggs and sperm and are called germ line mutations. No change occurs in phenotype.

Which conclusion is supported by the fact that the black-breed boar, with its quality meat, and the white-breed sow, with its qu

Answer:

Selective breeding combines ideal traits of animals to replicate in offspring

Explanation:

Selective breeding is the process which involves choosing parents with particular characteristics to breed together and produce offspring with more desirable characteristics. It is also known as artificial breeding and provides both plants and animals with greater variation and higher chances of survival. Selective breeding can be used to produce plants with bigger and tastier fruits and vegetables, crops with greater resistance to pests and diseases, and bigger animals that can be used for meat or milk production. The process of selective breeding is of great importance to the farmer today as it has brought about greater economic advantages.

In the instance of the black-breed boar and the white-breed sow being matched for mating, the reason is to combine these desirable traits in their offspring. The black-breed boar produces quality meat while the white-breed sow has quality fertility. Mating between these two breeds will produce offspring which has both traits of quality meat production as well as quality fertility.

I. Match the following.

dezoksy [38]

1. a minus-charged particle of an atom..... Electrons

2. a neutral (no charge) particle found in the nucleus of an atom..... Neutrons

3. a positive-charged particle in the nucleus of an atom.... Protons

4. a system of comparing atomic masses to carbon.... Relative mass

II. The atomic number of an atom is equal to the number of Protons.

III. The atomic number is always equal to the atomic mass. False.

IV. Atomic mass minus atomic number =number if neutrons.

V. A proton in the nucleus of an atom has an electrical charge of: +ve (positive).

VI. The atomic number of calcium is 20. This number means that calcium has 20 protons. The atomic mass of calcium is 40. How many neutrons does calcium have?

Answer: No of neutrons = atomic mass-atomic number

No of neutrons= 40-20=20 neutrons.

VII. Helium has an atomic number of 2. This number also means that helium has 2 protons. The atomic mass of helium is 4. How many neutrons does helium have?

Answer: No of neutrons = atomic mass-atomic number

No of neutrons= 4-2=2 neutrons.

VIII. The relative atomic mass of a proton or neutron is 1.

IX. The relative atomic mass is always a mass that is compared to the element Corbon.

X. Name the three kinds of sub-atomic particles found in an atom: electron, proton and neutron
