Answer:
The nucleotides are split
Explanation:
With the release of enzyme, enzyme take part in the chemical reaction without utilizing in it.
When the enzyme release by any glands in the body, it attached to the substrate and speed up the chemical reaction without using in it. Once the chemical reaction ended, the enzyme which attached the substrate earlier detached and then attached other substrate in order to speed up the chemical reaction.
Without enzyme, chemical reaction occurs but at a very slower rate so we can conclude that with the release of enzyme, enzyme take part in the chemical reaction without utilizing in it.

Which answer choice accurately depicts the sequence by which blood moves from the pulmonary vein to the body tissues?
Answer:
See the answer below
Explanation:
Oxygen-rich blood flows from the lung through the pulmonary vein to the left atrium of the heart. From there, the blood is pumped through the mitral valve to the left ventricle. The contraction of the left side of the heart sends the oxygenated blood out of the left ventricle through the aortic arch to the major arteries designated to carry blood to the major parts of the body. From the arteries, blood moves to the capillaries and then to the various tissues of the body before returning back to the heart through the vein.
Thus, the sequence of flow of blood from the pulmonary vein to the body tissues can be summarized as:
Pulmonary vein -> Left atrium -> Arteries -> Capillaries -> tissues

Place 14 oz of crushed ice into a small pot. Then add about 125 mL of water to it.
Using the thermometer, measure and record the initial temperature of the ice water. List this temperature in °C in the “0” minutes row of your data table in the lab handout. *Do not allow the thermometer to touch the bottom of the pot when recording measurements.
Place the pot on the stove, and turn the knob to the medium-low setting.
Using the thermometer, measure the temperature every minute until the water begins to boil vigorously. Record this data in the table on your lab handout.
At each measurement, also record what is happening to the water. Be sure to record the times of these events:
The ice melts.
The water forms steam.
The water begins to boil.
Once the water has begun to boil, stir the water constantly with the spoon.
Continue to measure and record the temperature every minute until almost all the water has boiled and the pot is close to empty.
Record the last temperature, and turn off the stove. DO NOT TOUCH THE POT WITHOUT SAFETY EQUIPMENT.
Create the x-axis and y-axis of a graph.
Label the x-axis as follows: Time (min).
Label the y-axis as follows: Temperature of Water (°C).
Along the x-axis, create and label 15 marks, one for each minute of the experiment. (Hint: The origin starts at 0.)
Along the y-axis, create and label temperature markings for every 20 degrees. (Hint: The origin starts at 0.)
Refer to the data from your experiment to plot the points on your graph. Then connect each of the data points with a line.
Look over your graph to make sure it is clear and correctly labeled.
Either save your graph as a computer file, or take a picture of your graph and upload it as a file on your computer.
Describe your experience in performing the experiment. What went well? What could have been
improved?
Examine your line graph. How does the graph’s slope change over time?
Examine your line graph. Why does the slope change?

if epigenetic changes take place above the level of the genome , what would be an example of a change at the level of the genome ?
Answer:
epigenetics chamges take place.
Epigenetics is the examination of the way cells manipulate gene interest without converting the DNA series." Epi-"approach on or above in Greek, and "epigenetic" describes elements past the genetic code.
Epigenetic changes are adjustments to DNA that modify whether or not genes are grown to become on or off. These adjustments are connected to DNA and do now no longer alternate the series of DNA constructing blocks. Within the entire set of DNA in a (genome), all the adjustments that modify the interest (expression) of the genes are referred to as the epigenome.
Because epigenetic changes assist decide whether or not genes are grown to become on or off, they affect the manufacturing of proteins in cells. This law facilitates making sure that everyone produces the handiest proteins which might be essential for its function. For example, proteins that sell bone boom aren't produced in muscle cells.
What is the epigenetic pattern?Patterns of epigenetic change range amongst individuals, in one-of-a-kind tissues inside an individual, or even in one-of-a-kind cells inside a tissue. Environmental influences, together with a person’s food plan and publicity to pollutants, can affect the epigenome. Epigenetic adjustments may be maintained from cell to as cells divide and, in a few cases.
Hence concluded that Epigenetics changes and causes cancers, by changing the genome, epigenome, or both.

B cells can divide to form plasma cells. Each plasma cell contains many mitochondria
and an extensive endoplasmic reticulum. Referring to the function of plasma cells in your answer, explain why these features are important adaptations.
Answer:
Explanation:
The presence of mitochondria and an extensive endoplasmic reticulum are the features that are important for adaptations of the plasma cell because plasma cells (white blood cells) secrete immune proteins also called antibodies which only formed due to the presence of endoplasmic reticulum whose function is to formed proteins for the cell so that's why plasma cells have large sized endoplasmic reticulum.

How do you think about the invention of the microscope? Influenced the cell theory?
And what are the components of the cell theory?
Answer:
See the answer below
Explanation:
The invention of the microscope paved way for the development of the cell theory because, without it, the cell and all the organelles of the cell would not have been discovered and or studied in great detail. It was through the use of a microscope that Robert Hooke was able to observe and name the cell and it was through the same microscope that the fine details of the cell were able to be studied by other scientists, culminating in the formulation of the cell theory.
The cell theory states that all living organisms are made up of cells, the cell is the basic unit of all life, and cells can only arise from already existing cells (via cell division). The components of the cell theory, therefore, are:
Living organisms are made up of cells.The cell represents the basic unit of life.Cells can only arise from preexsiting cells.How do living organisms return carbon to the atmosphere in the carbon cycle
Answer:
Carbon enters the atmosphere as carbon dioxide from respiration and combustion. Carbon dioxide is absorbed by producers to make glucose in photosynthesis
Living organisms return carbon to the atmosphere in the carbon cycle by two process namely respiration and combustion. Carbon dioxide is absorbed by producers to make glucose in photosynthesis.
What is photosynthesis?
A photosynthesis is a biochemical process which occurs in plants, algae, and bacteria, when they are exposed to sunlight. During photosynthesis, water and carbon dioxide join to form sugars and give off oxygen.
Respiration is defined as the inhaling of oxygen and the exhaling of carbon dioxide and combustion is defined as the process in which a substance burns in the presence of Oxygen, produce off heat and light in the process.
