ser-zykov [4K]2 years ago
6 0

Answer:

Lack of oxygen

Explanation:

There are two mechanisms for energy production (glucose breakdown), aerobic and anaerobic. When adequate amounts of oxygen are present, aerobic mechanism is used. However, when there is insufficient oxygen, such as during exercise, the anaerobic mechanism is used.

Which adaptation is the likely result of convergent evolution?
bezimeni [28]

A result of convergent evolution are the webbed feet of ducks and frogs.

Explanation:

The evolution of the animals, or rather the development of adaptive features, works in very interesting manner. It is very common in nature that animals that are closely related do not share similar characteristics, or the opposite, animals that are not closely related but share similar characteristics. The later case, is referred to as convergent evolution, where totally different animals have developed the same or very similar characteristics in order to be better suited for their environment.

In this case we have the ducks and frogs, and the webbed feet as shared adaptations, or feature. The ducks are birds, while the frogs are amphibians, and their last common ancestor has lived hundreds of millions of years ago. Despite that, both animals have developed webbed feet, and the reason for this has been that both animals have faced the same challenge, swimming and diving, and the webbed feet help them to be much faster and more agile in the water.

Other examples of convergent evolution (in the present and in the past) are:

  • Hyena - Tasmanian devil
  • Sandy cat - Fenec fox
  • Smilodon - Thylacosmilus
  • Bats - Birds

Use the drop-down menus to answer the questions about genetic recombination. involves the transfer of genetic material from one
Tresset [83]

The right matches are:

• Involves the transfer of genetic material from one bacteria to another ==> Genetic recombination (all 3).

• Involves scraps of genetic material ==> Transformation.

• Uses a virus to transmit genetic material ==> Transduction.

• Uses a pilus to transmit genetic information ==> Conjugation.

• Introduces new genetic material to a bacterium ==> Genetic recombination (all 3).

In molecular biology the term genetic recombination is often used as a synonym for DNA recombination, that is, the processes by which one DNA (or RNA) molecule is cut off, then joined to another.

There are three possible mechanisms in the bacterium: bacterial conjugation, bacterial transformation and transduction.

Which statement best describes the relationship between proteins and nucleic acids?
Iteru [2.4K]
Although the options are not provided, the statement best describing the relationship is nucleic acids provide blueprints for the construction of proteins.
Messenger RNA molecules (mRNA) take instructions from DNA molecules and take the code out of the nucleus. There, ribosomes work with the RNA molecules to produce a chain of amino acids, which in turn links and folds in a specific manner to form a protein molecule.
