Please find the summary of what happens during DNA replication below
Explanation:
DNA replication is the process by which a DNA molecule is duplicated into two identical copies. It occurs in the nucleus of the cell prior to any cellular division. The process includes:
- The double stranded DNA is first unwound by an enzyme called DNA HELICASE into a replication fork consisting of two single strands of DNA.
- Another enzyme called DNA POLYMERASE binds to the DNA and begins to add NUCLEOTIDES to each strand using complementary base pairing rule i.e. A-T, G-C. To do this, short sequences of RNA called PRIMER are synthesized by an enzyme called PRIMASE, which serves as building block for DNA polymerase to act.
- However, DNA POLYMERASE can only work in the 5'-3' direction i.e. on the leading strand which runs from 3'-5' direction. Short pieces of DNA called OKAZAKI fragments are synthesized on the lagging strand, which runs from 5'-3' direction.
- An enzyme called LIGASE joins the okazaki fragments together into a whole DNA on the lagging strand.
After the replication process which follows the SEMI-CONSERVATIVE MODEL of replication, each DNA molecule will contain one old strand called PARENT STRAND and one NEW strand.

A Bobcat with a mass of 45 kg is rock climbing on down a slope trying to ambush his prey. Suddenly 76 m
above him a rock dislodges and begins to fall. The Bobcat looks up and just then, wakes up 1 hr later a little
disoriented but ok. How fast was the rock going just as it bounced off his head?
Answers
The rock was going with a velocity of about 30.1 m/s just before it bounced off the bobcat's head.
How fast was the rock going just as it bounced off his head?This problem can be solved using the principles of conservation of energy, assuming that all the potential energy of the rock at the height of 76 meters is converted to kinetic energy just before it strikes the bobcat's head. We can use the equation:
potential energy = kinetic energy
mgh = (1/2)mv^2
where m is the mass of the rock, g is the acceleration due to gravity, h is the height of the rock above the bobcat, and v is the velocity of the rock just before it strikes the bobcat's head.
Substituting the given values:
m = unknown
g = 9.8 m/s^2
h = 76 m
v = unknown
We can solve for v as follows:
mgh = (1/2)mv^2
v^2 = 2gh
v = sqrt(2gh)
v = sqrt(29.876)
v = 30.1 m/s

The part of the hemoglobin molecule that combines with oxygen is the heme.
O True
False
Is it true or false
Answers
Answer:
Its true!!Explanation:
Actually the haemoglobin molecule consists of 2 parts, the haem which is a prosthetic group and the other globin which is a protein. So the haemoglobin as is a protein so, is arranged in quaternary structure of protein which contains 4 subunits. The subunits depend upon the organism whose haemoglobin is being talked about. So the normal haemoglobin found in red blood cells contains 2 alpha subunits + 2 beta subunits. At the centre of each subunit there is the haem part attached. To the centre of haem the Fe3+ ion are present which actually attaches to 1 Oxygen molecule. So as 4 subunits are present and each subunit has 1 Fe3+ ion, so total 4 Oxygen molecules can bind to the 1 Hb molecule!!

Answers
'The federal government cannot completely control the states' best completes the diagram.
What do you mean by Government?
Government is a system of organization through which a society or state is controlled, including its laws and policies. It is typically composed of an executive, legislative, and judicial branch, which operate together to ensure the protection of citizens and the effectiveness of laws and policies.
The federal government and the states exist in a system of shared power known as federalism. This means that the federal government and the states have certain powers that they can exercise independently of each other and that neither one can completely control the other. The federal government has certain enumerated powers such as the power to declare war, regulate interstate commerce, and raise taxes. The states, on the other hand, have the authority to pass laws on matters not specifically delegated to the federal government, such as education and local infrastructure. This division of powers ensures that the states maintain a certain level of autonomy and cannot be completely controlled by the federal government.
Hence, option A is correct.

I need 3 evidence and reasoning why more varieties of trees help the orangatans
Answers
Having more varieties of trees in orangutan habitats benefits these primates in multiple ways. It provides increased food availability, ensures nutritional diversity, and contributes to the overall health and sustainability of orangutan populations.
1.Increased Food Availability: Having a greater variety of trees in orangutan habitats provides them with a wider range of food sources. Orangutans are primarily frugivorous, relying heavily on fruits for their diet. Different tree species produce fruits at varying times throughout the year, and having a diverse array of trees ensures a more consistent and reliable food supply. This variety also allows orangutans to adapt to seasonal fluctuations in fruit availability and prevents overexploitation of specific tree species, promoting long-term sustainability.
2.Enhanced Nutritional Diversity: Different tree species offer varying nutritional compositions, including variations in vitamins, minerals, and other essential nutrients. A greater diversity of trees provides orangutans with a broader range of nutrients, contributing to their overall health and well-being. A balanced diet derived from a variety of trees can help address specific dietary requirements and support optimal growth, reproduction, and immune function in orangutans.
3.Improved Habitat and Biodiversity: The presence of diverse tree species creates a more complex and ecologically rich habitat for orangutans. Trees provide important resources beyond just food, such as nesting sites, shelter from predators, and pathways for movement. A greater variety of trees promotes biodiversity by attracting a wider range of other plant and animal species, creating a balanced ecosystem. This biodiversity is crucial for the long-term survival of orangutans as it helps maintain ecosystem stability, resilience, and the availability of resources.
Furthermore, a diverse tree population creates a richer and more resilient habitat, supporting a variety of species and promoting a healthy ecosystem for orangutans to thrive in.

At a blood bank there were five problems with a laboratory technician's work performance the first year at work
Answers
The supervisor at the blood bank would likely consider spilling 5 units of blood (problem 2) as the most serious issue among the listed problems. While all the problems listed have their own level of seriousness, spilling 5 units of blood poses significant concerns. The correct answer is 2.
Spilling 5 units of blood represents a critical error with potentially severe consequences. Blood is a valuable and potentially life-saving resource, and any loss or contamination can have serious implications for patient care.
It not only wastes precious resources but also poses potential risks to both patients and staff members, including the potential for infections and the need for additional blood collection.
While other problems like coming to work late, working too slowly, mislabeling units of blood, or breaking a microscope lens can impact efficiency, accuracy, and productivity, they may not directly jeopardize patient health and safety to the same extent as spilling blood.
Therefore, the supervisor would likely consider the spilling of 5 units of blood as the most serious problem, requiring immediate attention, investigation, and measures to prevent such incidents in the future. Therefore, the correct answer is 2.

Sara and Juan conducted an experiment to test which soil would be BEST for growing plants. They planted bean seeds in four pots and placed the pots in the sunlight. Each pot had a different type of soil. They used all three types of soil seen in the jar: sand, silt, and clay. They also made a mixture of soil using equal parts of sand, silt, and clay. Once the seeds were planted, they watered the pots every day and tracked the seed germination and plant growth.
What was the dependent variable in the experiment?
Answers
The dependent variable in the experiment conducted by Sara and Juan to test which soil is best for growing plants is likely the plant growth or the plant's response to the different types of soil.
This variable is dependent on the independent variable, which is the type of soil (sand, silt, clay, or the mixture) used in each pot. By observing and measuring the plant growth, they can determine which type of soil yields the best results in terms of seed germination and overall plant growth.
It's important to note that the dependent variable can vary depending on the specific focus of the experiment. In this case, since the aim is to determine the best soil for growing plants, the growth and development of the plants would be a relevant measure.
Other possible dependent variables could include factors like plant height, leaf size, number of leaves, or even the number of flowers or fruits produced. The specific measure chosen as the dependent variable would depend on the objectives and hypothesis of the experiment.
