Answer:

Many flowers use visual cues to attract pollinators: showy petals and sepals, nectar guides, shape, size, and colour. I personally think it is very cool how they know what to do to attract pollinators.

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, Guanine, 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.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is condensed and tightly wound around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.

Nucleic acids like DNA stores all of an organism’s genetic information. Nucleic acid molecules comprise the nitrogenous bases Guanine, Adenine, Cytosine and Thymine. Conversely, RNA nucleotides are Adenine, Guanine, Cysteine and Uracil. These pair up as base pairs due to their varied structure- largely influenced by the location of N molecule.

In certain combinations, these bases form codons which act as instructions for protein synthesis. Codons are three nucleotide bases encoding an amino acid or signal at the beginning or end of protein synthesis. Thus, these contribute to the broad diversity of living organisms, as varied combinations of these 64 codons can produce many proteins which can be organized into cells, tissues and organisms.

What is transcription and why is it important in making proteins

Nostrana [21]

Answer:The goal of transcription is to make a RNA copy of a gene's DNA sequence. For a protein-coding gene, the RNA copy, or transcript, carries the information needed to build a polypeptide (protein or protein subunit). Eukaryotic transcripts need to go through some processing steps before translation into proteins.

The original source of all genetic variation is _____. the original source of all genetic variation is _____. sexual reproductio

IceJOKER [234]

The answer for the above question is Mutation.
Mutations are random spontaneous changes that occur suddenly in the DNA. A single mutation can have a large effect, however in may cases evolutionary changes are based on the accumulation of many mutations. The gene flow is any movement of genes from one generation to another and is an important source of mutation

Which of the following describes the outer core?

A. The solid, rocky layer on the outside

B. A layer of liquid metal that spins

C. A dense layer of solid metal

D. Hot, partially melted rock that flows

Because the outer core is the third layer of the Earth. It is the only liquid layer, of metals irons and nickel Also its responsible for Earths magnetic field as earth spins on its Axis the substances move also move around during that

change in temperature and pH can change the shape of the enzyme and They can break down the reactants

Temperature. Higher temperatures typically result in faster rates of reaction, whether they are enzyme-catalyzed or not. The chemical bonds in the active site, however, can be impacted by temperature changes that are either too high or too low and make them less able to bind substrates. Extremely high temperatures (over 40 degrees Celsius may cause animal enzymes to denature, losing their form and activity)

pH can also affect enzyme function. The acidic or basic characteristics of active site amino acid residues are frequently crucial for catalysis. These residues can be impacted by pH changes, which can make it difficult for substrates to bind. Like with temperature, certain pH ranges (acidic or basic) can cause enzymes to denature. Enzymes function best within these pH ranges.
