Explanation:

Codons are three nucleotide bases encoding coding and amino acid or signal at the beginning or end of protein synthesis. In the genetic code, an amino acid is encoded by 3 nucleotides, while there are just 4 bases.A set of amino acids, 20 in total, build proteins from numerous configurations

∴ for 20 amino acids, and 4 nucleotides a minimum of 3 bases is required $N^{3}$ = $4^{3}$ = 64 possible codon arrangements

Given the degeneracy of the genetic code- the code contains more information that necessary multiple codons encode the same amino acid.

e.g.UUA and UUG encode the amino acid Leucine

Further Explanation:

The nucleic acids are comprised of smaller units called nucleotides and function as storage for the body’s genetic information. These monomers include ribonucleic acid (RNA) or deoxyribonucleic acid (DNA). They differ from other macromolecules since they don’t provide the body with energy. They exist solely to encode and protein synthesis.

Basic makeup: C, H, O, P; they contain phosphate group 5 carbon sugar does nitrogen bases which may contain single to double bond ring.

RNA codons determine certain amino acids so the order in which the bases occur within in the codon sequence designates which amino acid is to be made bus with the four RNA nucleotides (Adenine, Cysteine and Uracil) Up to 64 codons (with 3 as stop codons) determine amino acid synthesis. The stop codons ( UAG UGA UAA) terminate amino acid/ protein synthesis while the start codon AUG begins protein synthesis.

The wobble hypothesis states that the first two bases within a codon for an amino acid have an exact pairing with anticodons of tRNA. However, the pairing of the third bases may vary or wobble- thus a tRNA can recognise multiple codons. This explains how multiple codons can encode the same amino acid.

Which of the following pairs of protists and their ecological roles are correctly matched?

melisa1 [442]

Answer:

The correct pair is A: "apicomplexans—parasites of animals"

Explanation:

Euglenophyta is a group of unicellular, eukaryotic organisms. They are small, free-living forms, or parasites that present different feeding mechanisms and behaviors, such as heterotrophy, autotrophy, or mixotrophy.

Dinoflagellates are unicellular, flagellated, free-living protists that might form colonies. Most of them are autotrophic organisms but some of them are heterotrophic, or mixotrophic. In these last cases, dinoflagellates can feed on other dinoflagellates, protozoans, or diatoms. They can also be parasites.

Entamoebas are endoparasitic organisms with no mitochondria as an adaptation of living in environments with low oxygen concentration.

Apicomplexa is a unicellular, protist group. They have medical and economic importance as they are<u> animals</u> and human parasites. They have an apical complex that helps them to fixate to the host cell and release a substance that provokes an invagination in the host membrane. This invagination allows the parasite to get into the host cell.

Phytoplankton form the base of food webs, but are only present in the upper few hundred meters of the ocean. A number of factors

Ksenya-84 [330]

Answer:

The correct answer is d. Oxygen

Explanation:

Phytoplanktons are responsible for the fixation of approximately half of the global carbon therefore seawater has high CO2 concentration which is required by phytoplanktons to make their food.

They are the primary producers of oceans and they are responsible to support the food chain of oceans. Factors that can limit their growth are mainly sunlight and nutrients like phosphorus, nitrogen, etc.

As phytoplanktons are photosynthetic they release oxygen itself as a byproduct therefore oxygen is not a limiting factor to phytoplanktons. So the right answer is d.

What has allowed animals to adapt over time?

jeka94

Natural selection ensures that animals with features that increase their chances of survival are more likely to live and pass those traits on to their progeny.

Animals adapt to their surroundings over a lengthy period of time, which causes those changes. The evolution of adaptations happens across many generations.

<h3>What is an adaptation?</h3>

A physical or behavioral characteristic of an animal that enhances its ability to survive in its environment is known as an adaptation.
To put it another way, an adaptation is something a species does or has on them that makes it easier for them to locate food, water, mates, and shelter.
Among the adaptations that helped animals live and prosper on land are:

Gas exchange using a moist membrane
The ability to traverse land (limbs instead of fins)
The capability of body water conservation
The capability of reproduction and early habitability
The capacity to endure fast environmental changes

<h3>What are the types of adaptation?</h3>

Depending on the environment, there are three basic types of adaptations: behavioral, structural, and physiological.

Physiological- When an animal's body's internal mechanisms adapt to its surroundings.

Structural - Over the course of millions of years of evolution, the animal's bodily features alter.

Behavioral - Animals adjust their behavior in reaction to their environment.
