Answer:

Hybridization - a method that unionizes gametes of differing genes to create a new individual

Recombinant DNA - cultured DNA molecules from different biological sources

Selective breeding - a process of breeding organisms because of their specific traits

Explanation:

In biology, hybridization is the process of creating a hybrid by combining gametes of different species or varieties. An example of a hybrid is a liger - an offspring of a lion and a tiger.

Recombinant DNA is DNA created in the process of genetic recombination. Genetic material from multiple sources is combined, creating sequences that do not occur in the genome naturally.

Selective breeding is the process of breeding organisms with desirable characteristics. For example, a good dog breeder will breed only two completely healthy dogs in order to make sure that the puppies don't have any health issues often associated with the breed.

During cellular respiration what is the direct source of the energu used in the cells of consumers?
nexus9112 [7]

Answer:

Consumers use chemical energy from the chemical bonds within organic molecules such as carbohydrates, lipids,  and amino acids.

Explanation:

<u>Heterotrophs are consumers</u>; they ingest or absorb organic matter (lipids, carbohydrates, proteins, etc.)  made by autotrophs or producers for their energy consumption. Autotrophs include plants, bacteria, and other photosynthesizing organisms, while heterotrophs include animals, fungi, protists, and bacteria.

Heterotrophs obtain energy from food through the process of cellular respiration. For instance, during aerobic respiration in mitochondria, they break down sugars in the form of glucose into carbon dioxide and water to obtain energy in the form of ATP or adenosine triphosphate.

aerobic respiration:      C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP

                                      glucose+ oxygen →  carbon dioxide+ water+ energy

Arrange the sentences in order to describe how oxygen from air is transported to the cells in the kidneys.
AURORKA [14]

Answer:

The pulmonary veins carry oxygenated blood to the heart. Air enters the bronchioles in the lungs and reaches the alveoli. The capillaries join together to reach the arteries, transferring the oxygen. The oxygen-rich blood moves from the aorta and reaches the kidneys through a series of blood vessels.

Answer:

Paradoxides pinus belong to the life forms that existed during the Cambrian period.

Explanation:

Paradoxides pinus is a form of trilobites that thrived all over the world during the middle of the cambrian period as per index fossils. Structurally, they are found to possess semi circular like head with the cheeks curving into structures that resemble spines. Their eyes are sickle shaped for they are believed to have all round vision. The exoskeleton is large and often flattened or oval in shape with greatest width along the re-curved spine.
