The best explanation for the presence of vestigial pelvis and femurs in some snake and whale species is

Answers

Answer:

a common ancestor that used these structures to perform one or more specific functions

Explanation:

A vestigial structure is an organ that has no obvious function in an organism, but it has been used by a past ancestor to perform one or more specific functions. Thus, vestigial structures have been retained in the course of evolution, but they lost their ancestral functions. Vestigial structures/organs can be detrimental for the organism because it is required energy to maintain them and they may suffer diseases (e.g., cancer). Some well-known examples of vestigial organs/structures include, among others, the wings of ostriches and cormorants, the human appendix, etc.

Answer:

The correct answer is - A large amount of sea life is being taken from the ocean to feed other creatures.

tRNA uses (anticodons/codons) to match to the mRNA.

Answers

Answer:

anticodons

Explanation:

codons are for mRNA

tRNA uses anticodons to match to the mRNA.

Which one does tRNA uses?

tRNA (transfer RNA) molecules are responsible for carrying specific amino acids to the ribosomes during protein synthesis.

They have an anticodon region that consists of three nucleotides that are complementary to the codons on the mRNA (messenger RNA). The codons on the mRNA determine the sequence of amino acids in the growing polypeptide chain.

The anticodon on the tRNA base pairs with the complementary codon on the mRNA, ensuring that the correct amino acid is incorporated into the growing protein chain. The matching between the anticodon and codon is essential for the accurate translation of genetic information into protein synthesis.

(A) During active transport the water inside the cell is used to transport substances throughout the cell. Passive transport uses the cell's cytoplasm to move substances around the cell.

(B) Passive transport moves substances throughout the cell without using the cell's energy and active transport moves substances using the cell's energy.

(C) Active transport moves substances from higher concentrations to lower concentrations and passive transport moves substances from lower concentrations to higher concentrations.

List one organism and describe all of its adaptations.​

Answers

Adaptation is a mechanism of species to survive and reproduce in their environments, adjusting to selective pressures. Cactus: leaves, stems, spines.

What is adaptation?

In biology, adaptation might be defined as the mechanism of organisms to improve their fitness in the environment in which they live, adjusting to different changes and selective pressures acting on them.

Adaptation involves molecular, physiological, morphological, and behavioral changes.

For these changes to persist and be transmitted from generation to generation, they must increase the individual's fitness. They must increase the individual survival and reproductive probabilities, making it more competitive.

A good and easy to unsderstand example of adaptation is the cactus.

Cactusses are plants adapted to dry and hot environments like deserts, where water availability is scarse and temperatures are high.

To avoid dehydration, cactusses have developed wide palmated or cilindirical stems and reduced or vestigial leaves.

They use stem tissues to store water. Vestigial or reduced leaves to avoid transpiration and water loss.

As their leaves are not developed, their stems photosynthetize to produce organic compounds.

Some species are very rich in water and nutrients, so they turn to be covetted by other species. Animals living in the same environment look for them as a source of food.

To avoid predation, cactusses have developed large and numeros spines that are leaves modifications. This is another adaptation to avoid being eaten by animals and avoid loosing water through leaves.
