To protect an endangered species, a group of biologists have decided to store the genes of the species. They think that this wil
Ganezh [65]

Answer is C. genome conservation.

A set of DNA, including all of its genes makes up genome of an organisms. Each genome contains all of the information needed to build and maintain that organism. The population of endangered species is small which suffer from reduced genetic diversity through inbreeding.

In conservation genomics, the study of genetic diversity in all genes is carried out for better understand their implications to ecology, health, and disease. This random loss of genetic diversity in diminishing populations is a process known as ‘genetic drift’ and is further complicated by ‘inbreeding depression’, where related individuals breed with each other which results in further loss of genetic diversity.  

Using genome editing techniques to carefully reintroduce the lost genetic diversity back into the current, endangered population.

Two nuclei combine to form one nucleus in nuclear fission.
andre [41]
The answer is false.

The two main nuclear processes are nuclear fission and nuclear fusion.

In fission, a large nucleus is bombarded with a high energy neutron, resulting in the breakdown of the nucleus and the release of two smaller nuclei along with neutrons and high amounts of energy.

In nuclear fusion on the other hand, two smaller atomic nuclei possessing high amounts of energy to form a larger nucleus, with the possible release of neutrons. This process is also highly exothermic.

Blood is found in which of the following areas of the heart just before it is pumped into the lungs?A. the superior vena cavaB.
Stells [14]

Answer: E- The right ventricle.

Explanation: Deoxygenated blood with carbon dioxide and metabolic products collected from the tissues by the capillaries returns to the heart via the venous system and enters the right atrium of the heart. It is then pumped to the right ventricle, then transported to the lungs via the pulmonary artery for gaseous exchange, where oxygen is collected and carbon dioxide is dropped off.

Air is made up of different gases, such as oxygen, nitrogen, and carbon dioxide.
evablogger [386]

Answer:

<em>The correct option is A) they are all classified as pure substances.</em>

Explanation:

Pure air is a term which is used to described air which is free from pollutants or other contaminants. All the substance from which air is made are considered as pure substances. Hence, option A is correct.

Other options, like option C, is false because the components of the air are no chemically bonded to one another. They exist freely. Options D is false because not all the components of air can be classified as an element. For example, carbon dioxide is not an element.
