Answer:
The type of mutation that occurs when in the DNA strand there is a change from guanine to cytosine is a nonsense mutation, since the triplet that should encode the amino acid encodes a stop codon and the protein cannot be completely synthesized.
Explanation:
The nonsense mutation consists of a change in one of the bases of the stranded DNA, which is transcribed into an altered mRNA, producing a stop codon, instead of an amino acid.
In the table it is observed that the CCA codon is a stop codon that cuts off the protein synthesis prematurely, leaving it incomplete and probably non-functional.
Sometimes this type of mutation can alter the sequence of amino acids but the protein may be complete enough to partially fulfill its function.
can someone confirm if this is the right sequence?

animals obtain glucose from ?
Answer:
[tex]\boxed {\boxed {\sf Eat \ other \ plants \ and \ animals}}[/tex]
Explanation:
Plants, algae, and certain bacteria can photosynthesize and make their own food by converting carbon dioxide, water, and sunlight to glucose and oxygen.
Animals cannot undergo this process and produce their own food, so they have to eat food to obtain glucose.
Animals get glucose and energy by consuming plants or other animals.
Animals obtain glucose from the food they consume.
How do animals obtain glucose?When animals eat carbohydrates, such as sugars and starches, their digestive system breaks them down into simpler molecules, including glucose.
Glucose is then absorbed into the bloodstream and transported to cells throughout the body, where it is used as a source of energy for various metabolic processes.
In addition to carbohydrates, animals can also obtain glucose from other nutrients like proteins and fats through processes like gluconeogenesis, where these molecules are converted into glucose when needed by the body.

Cells spend very little of their life performing mitosis. Most of a cell’s life cycle is spent in interphase. Interphase is made up of the first growth phase, the synthesis phase, and the second growth phase. The synthesis phase is characterized by -
The division of cytoplasm
Cell division
Replication of mitochondria and other organelles
DNA replication
Answer:
DNA replication
Explanation:
Synthesis is the stage characterized by DNA replication. It is after the G1 phase
Most of the cell's time is spent in the interphase. The first growth phase comes first, then the synthesis phase, and finally the second growth phase. In the synthesis phase, DNA replication occurs. So the last option is correct.
What is interphase in a cell cycle?
The interphase is the preparatory phase of the cell before going into the division phase (M phase). The first phase is the G1 phase, or first growth phase, in which the cell grows in size. Then the cell enters the synthesis phase, or S phase, where the cell's genetic material, which is DNA, is replicated.
A single DNA molecule duplicates itself, but the two DNA molecules are linked by a single centromere. In synthesis phase the centrosome replicates too, making two centrosomes. Then the cell enters the second growth phase, or G2 phase. Here the cell again grows for the division.
Hence, in the synthesis phase, DNA replication occurs. The last one is correct.

Answer:
Plankton use carbon to make carbonate (CO3) shells in the ocean. The shells sink and accumulate into layers of sediments and eventually rocks. Rocks are pushed deep into the earth and melt at subduction zones, dissolving the carbon. Volcanic eruptions release carbon dioxide into the atmosphere.

How does osmosis of water occur across the cell membrane?Plz help I need it ASAP
Answer:
In osmosis, molecules cross the cell's plasma membrane to achieve equilibrium.
Explanation:
A bilipid layer called a plasma membrane typically surrounds cells. Here, lipid molecules are arranged tail-to-tail, with their heads facing outwards. The heads of the lipids, are water soluble, while the tails are insoluble. Proteins and cholesterol also help maintain membrane fluidity.
With the use of its transport proteins, pores and gated channels, embedded among the lipids the membrane maintains its concentration of substances through selective permeability.
Simple diffusion occurs in cells through plasma membranes as a means of passive transport. In osmosis, molecules of water move across the membrane, down their concentration gradient- i.e. they try to balance their concentration or number of water particles.
The water particles move from regions of high concentration to regions of low water concentration. Typically these 'destinations' or regions have large amounts of solute which contributes to the formation of this gradient.

Do you now notice any signs of growth? In which part of the ginger piece do you
notice growth occurs?
is there a picture near the question?
In ginger, growth can be seen in the rhizome, it is a modified root. The rhizome grows the plant.
What is growth?Growth is the constant expansion of an organism's size through time. It could also be described as one of a living thing's traits. "Biological growth" in biology refers to development that occurs throughout time. Throughout their lives, living creatures frequently expand. But it is a process that unfolds gradually and on a regular basis.
Typically, growth starts when a single cell is present. This cell may divide and enlarge in a particular area, as in plants, or it may diversify and enlarge over the entire organism, as in mammals.
The environment and internal elements have a large role in determining how rapidly or slowly an organism will grow. These variables have undergone centuries of change, changing how living things behave. Thus, growth can be in rhizomes in ginger.
