Answer:
35% thyamine, 15% guanine and 15% cytosine
Answer:
35% thymine, 15% guanine and 15% cytosine
Explanation:
35% thymine, 15% guanine, and, 15% cytosine because the exact same amount of thymine would pair up with adenine, thus thymine has to be 35%. Thymine and adenine take up 70% of the DNA the rest has to equal 30%. Guanine and cytosine make up the rest, which is 30%, thus we have to split it evenly because they pair up with each other. Therefore, guanine and cytosine equal 15%.
Why do you think the strand of DNA
coming in from the left side of the screen
is becoming two thinner strands?
Answer:
they might be spliting(reproduction) to make offspring
Explanation:
DNA replication
What does it mean when DNA splits?
Two strands of DNA come together to form a twisted, ladder-like structure. Hydrogen bonds between the bases of each strand create the double-stranded structure. The cell must split the two strands to allow the replication machinery to access each strand and copy it.
What causes the DNA to split apart during replication?
In order to unwind DNA, these interactions between base pairs must be broken. This is performed by an enzyme known as DNA helicase. DNA helicase disrupts the hydrogen bonding between base pairs to separate the strands into a Y shape known as the replication fork.

Which of the following correctly shows how energy flows in an ecosystem? *
producer - sun - decomposer – consumer
sun - producer - consumer – decomposer
decomposer - producer - consumer – sun
consumer- decomposer - sun – producer
Answer:
The correct answer is - sun - producer - the consumer – decomposer.
Explanation:
Sun is the ultimate source of the energy on the earth and is responsible for all the energy that is present or moves between various organisms in an ecosystem.
Sun provides energy in the form of light energy which is converted by the producers by photosynthesis into food and when consumers eat producers for food and energy 10 percent of energy passes from the producers to the consumers and the rest 90% lost during life processes. At the end of the chain, decomposers get energy from the dead matter of the consumers.

What is an advantage and disadvantage of using 4.5-7.5 pH paper?
Answer:
The correct answer would be:
Advantage: helps in finding the exact ph value with a narrower range.
Disadvantage: You don't know the exact ph value on a regular scale.
Explanation:
The pH paper is a pH paper with a color indicator that helps in determining the pH value precisely between the 4.5 to 7.5 pH range. It is accurate in comparison to other pH papers such as 0-14 paper. One no need to guess the color between the different colors from various color mixtures as it has a more precise color reading that helps in finding accurate pH value in a narrow range.
On a regular scale, it is not as accurate and one can not find the exact value as it provides a narrow range value between 4.5 to 7.5.

What is is the importance of the ph level of body fluids in the human body
Answer:
Your body's pH balance, also referred to as its acid-base balance, is the level of acids and bases in your blood at which your body functions best. The human body is built to naturally maintain a healthy balance of acidity and alkalinity. The lungs and kidneys play a key role in this process.

What is an ecosystem?An ecosystem can be defined as a biological community that is typically made up of living organisms (biotic factors) such as individuals and the physical environment (abiotic factors) in which they interact.
Basically, the individual organisms in an ecosystem forms a population and this also gives rise to a community. This ultimately implies that, the ecological levels of organization are ranked in ascending order as follows:

Bacteriophages that induce bacterial cell lysis are called
Answer:
Bacteriophages that induce bacterial cell lysis are called virulent phages.
Explanation:
Bacteriophages correspond to viruses with an affinity for prokaryotic cells to be used as hosts for replication. They act both by invading the bacterial cell and by introducing their genetic material into it.
Some bacteriophages are capable of lysing or destroying the host bacterial cell after replication of their genetic material, receiving the name of virulent phages.
Bacteriophages that induce bacterial cell lysis are known as VIRULENT phages.
A bacteriophage is any virus capable of infecting and replicating within a prokaryotic cell (i.e., bacteria and archaea).Bacteriophages can be classified as lytic bacteriophages, which replicate through the lytic life cycle, and temperate bacteriophages, which replicate using both lysogenic and lytic cycles.For example, the phage lambda of Escherichia coli is an example of a temperate bacteriophage.In conclusion, bacteriophages that induce bacterial cell lysis are known as VIRULENT phages.
