how is the classification of living things related to the structure of their cells?
Answer:
The most basic classification of living things is kingdoms. ... Living things are placed into certain kingdoms based on how they obtain their food, the types of cells that make up their body, and the number of cells they contain. Phylum. The phylum is the next level following kingdom in the classification of living things.
Explanation:
hope these help
The classification of living things significantly depends on the structure of their cells and based on this, they are divided into two types. They are as follows:
Prokaryotes. Eukaryotes. What do you mean by Cell structure?The structure of a cell may be defined as the components through which it has developed. It includes the cell membrane, the nucleus, and the cytoplasm. The cell membrane is a semi-permeable membrane that separates the inner atmosphere of the cell from the outer environment.
The nucleus is a structure inside the cell that contains the nucleolus and most of the cell's DNA. It is also where most RNA is made. When it comes to prokaryotes, they lack a well-defined nucleus and other membrane-bound cell organelles.
Eukaryotic cells generally have a well-defined nucleus and other membrane-bound cell organelles. Apart from this, these types of cells are generally highly compartmentalized as compared to prokaryotic cells.
Therefore, the classification of living things significantly depends on the structure of their cells that has been described above.

Explanation:
Mutation 1 will cause translation to stop as there is presence of stop codon UAG, UAA, UGA.
What are the stop codons ?
In DNA or messenger RNA (mRNA), a stop codon is a sequence of three nucleotides (a trinucleotide) that tells the cell to stop making proteins. There are 64 distinct codons for trinucleotides. Three stop codons (UAA, UAG, and UGA) and 61 specific amino acids are included.Several codons, or triplet bases, make up the universal genetic code. To reduce coding errors, the standard code has developed over time. The genetic code is made up of 64 codons that are the result of the four bases in nucleic acids being permuted and combined.Since more than one codon can encode for a single amino acid, the genetic code is degenerate. Consequently, 61 of the 64 codons encode the 20 amino acids.The START and STOP codons, two punctuation marks in the genetic code, indicate the conclusion of protein synthesis in all organisms.Because it is the first codon in the transcribed mRNA to undergo translation, the codon AUG is referred to as the START codon. The amino acid methionine (Met) in eukaryotes and formyl methionine (f Met) in prokaryotes are both encoded by the most prevalent START codon, AUG. With the assistance of a few initiation factors, the t RNA recognizes the START codon AUG during protein synthesis and initiates mRNA translation.Amber (UAG), opal or umber (UGA), and ochre (UAA) are the three STOP codons. Charles Steinberg and Richard Epstein discovered Amber" or UAG and gave it the name "amber" after the German meaning of their friend Harris Bernstein's last name. In order to keep with the theme of "color names," the two remaining STOP codons were subsequently given the names "ochre" and "opal."To know more about codons check this:

15. Why or why not?
Changing one base letter on a mRNA codon will always change the amino
acid it codes for.
A codon is referred to as a trinucleotide sequence found in DNA or RNA.
Each codon which is usually 61 number have a unique amino acids in which
they code for.
When one letter of the codon is changed, the amino acid in which it codes
for will also be affected and changed.

A the chemical changes that occur during the light independent reactions
B. the chemical changes that occur during the light dependent reactions
C. the source of carbon atoms in the carbohydrate product
D. the identities and roles of electron carriers
Answer:
A
Explanation:
Occur during light reaction process to manufacture food and release oxygen
.
The overall chemical equation that describes photosynthesis is the chemical changes that occur during the light independent reactions(option -A).
Why is the process of photosynthesis named that?Light energy is converted into chemical energy during photosynthesis by phototrophs, which is subsequently used to drive cellular functions. The form in which the chemical energy is stored is in the form of sugars, which are produced from water and carbon dioxide.
Photosynthesis' main job is to transform solar energy into chemical energy and then store that chemical energy for later use. The majority of the planet's biological systems are propelled by this process.
Anoxygenic and oxygenic photosynthesis are the two forms. The former is the more prevalent type, found in plants, algae, and cyanobacteria, and they both operate on very similar principles.

which of the following can be changed during meiosis? Is it a base sequence, a number of amino acids, a number of chromosomes, or a gene sequence
Answer:
Number of chromosomes
Explanation:
Meiosis is a specialized type of cell division in which the gametes are produced.
A diploid parent cell first replicates its DNA. Then, two rounds of cell division occurs to produce 4 haploid cells, each with half the amount of chromosomes. These gametes fuse during fertilization to restore the diploid state.
Therefore, meiosis changes the number of chromosomes.

A mutation has occurred that results in a drastic reduction in mRNA transcription from very high levels to low levels. What region is likely responsible?
Answer:
Enhancer region
Explanation:
An enhancer is a cis-regulatory DNA region that binds to transcription factors in order to stimulate transcription. Enhancer regions are localized both upstream and downstream of the gene whose transcription regulates, at a variable distance ranging from 1 to 100 kilobases (kb) from the transcription start site. The first enhancer to be identified was found in an intron of the immunoglobulin gene. Conversely, a silencer element is a DNA region that binds to proteins known as repressors in order to suppress transcription.
