which of the following is not a necessary life function? select one: a. nutrients b. reproduction c. metabolism d. movement
Nutrients are not a necessary life function as it is not directly necessary to maintain the life of the individual organism. It only helps in the breakdown of food to give them energy.
What are the life functions?
Living organisms are systems made from cells and are capable of life functions such as organization, metabolism, responsiveness, movements, transport, respiration, excretion, digestion, responsiveness, growth, regulation, differentiation, synthesis, and reproduction.
All living organisms have certain characteristics that distinguish from non-living forms. All of these processes are interrelated. From smallest cell to a complete body system do not work independently.
Metabolism is the sum total of all the chemical reactions occurring in the body. One of the reactions includes catabolism which helps to break complex substances into simpler building blocks. Another phase of metabolism is anabolism in which complex substances are formed from simpler ones. Responsiveness or irritability is concerned with detecting changes in the internal or external environments and reacting to that changes.Differentiation is a developmental process by which unspecialized cells change into specialized ones with distinctive structural and functional characteristics.Digestion is the process of breaking down complex ingested foods into simpler molecules that can be absorbed into the blood.Hence nutrients are not directly a necessary life function.

If the genetic code consisted of codons with 4 nucleotides, how many different codons could there possibly be?.
If the genetic code consisted of codons with 4 nucleotides, there could be 256 different codons possible.
The genetic code is a set of rules that living cells use to convert information encoded in genetic material into proteins. Each gene's code employs various combinations of the four nucleotide bases of DNA — adenine (A), cytosine (C), guanine (G), and thymine (T) — to spell out three-letter "codons" that specify which amino acid is required at each position within a protein.
A codon is a unit of three adjacent nucleotides that codes for an amino acid. Codons, which are three-letter nucleotide chains, make up the genetic code. Each codon represents a single amino acid.

What level of transcription would you predict for a gene whose promoter is heavily methylated?.
Low transcription if promoter is heavily methylated.
In genomics, transcription is the process of creating an RNA copy of a gene's DNA sequence. This copy, known as messenger RNA (mRNA), transports the protein information encoded in the gene's DNA. A gene cannot be used to make a protein in a cell if it is not transcribed. If a gene is transcribed, it will almost certainly be used to produce a protein (expressed). Generally, the more a gene is transcribed, the more protein is produced.
Gene expression is specifically regulated on two levels. First, transcription is controlled by limiting the amount of mRNA produced by a specific gene. The second level of control comes from post-transcriptional events that regulate mRNA translation into proteins.

how is leaves change color related to photosynthesis
Answer:
Explanation:
Chlorophyll Breaks Down
But in the fall, because of changes in the length of daylight and changes in temperature, the leaves stop their food-making process. The chlorophyll breaks down, the green color disappears, and the yellow to orange colors become visible and give the leaves part of their fall splendor.
Answer: Chlorophyll
Explanation:
Photosynthesis takes place because the cells of the leaf contain the pigment chlorophyll, a bright-green pigment that gives leaves their green color. As fall approaches, trees seal off leaves from the rest of the plant in order to prevent water loss from stomata. Once the leaves are sealed off, the leaf stops producing chlorophyll. Additionally, any chlorophyll remaining in the leaves begins to break down. As the chlorophyll degrades in the leaves, the bright green color disappears. With the green pigment gone, the colors of the other pigments within the leaf can finally be seen.
In other words, those beautiful oranges and yellows that we associate with fall leaves are actually present in the leaves all along—they have just been masked by the green chlorophyll. With the chlorophyll gone, their true colors can be seen.

individual organism can adaptTrue, But it has to increase their fitnesssometimes, it depends on where they are located if the adoption is helpful or notfalse, only a population can adapt
Organisms can adapt to different environments, however, this usually occurs over generations and at the population level. At the level of the individual, an example is mutations, in which the offspring may have different characteristics from the progeny. However, these adaptations of the offspring will either be detrimental or give an advantage depending on the environment in which it is
Because these changes occur gradually over generations, individual organisms cannot increase their fitness on their own. And although there are special cases in which an organism can adapt to environmental changes through a phenomenon called phenotypic plasticity, this is not common in all species and is not due to a genetic change in the individual. Therefore, the answer would be B (sometimes, it depends on where they are located if the adaptation is helpful or not).

What is DNA polymerase?A DNA polymerase belongs to a group of enzymes that catalyzing the synthesis of Dna strands using nucleoside triphosphates, which are the basic building blocks of DNA. These enzymes, which are necessary for DNA replication, typically function in groups to split one single original DNA duplex into two identical DNA duplexes. One nucleotide at the a time, DNA polymerase inserts nucleotides to a DNA strand's three primary (3')-end. DNA polymerases are needed to duplicate a cell's DNA each time it divides in order to send a replica of the original DNA molecule to each daughter cell. This is how genetic information is transmitted down through the generations.
