There are a number of key enzymes that function in the replication of DNA. Using your book and other resources, identify what these key enzymes do.
DNA Polymerase (identify two jobs):
Helicase:
Primase:
Ligase:

Moles are small mammals that are virtually blind and live in underground burrows for most of their lives. This is an example of the interaction between which Earth's systems?
A. biosphere/lithosphere
B. Lithosphere/hydrosphere
C. hydrosphere/biosphere/lithosphere
D. Atmosphere/lithosphere/hydrosphere
Answer:
A. biosphere/lithosphere
Explanation:
The habitat of moles in underground burrows shows the interaction between the biosphere and lithosphere.
The biosphere the region of the earth occupied by living organisms.
The lithosphere is the solid part of the earth
Organisms interacts with the lithosphere in diverse ways. For underground burrowers, their dwelling place is situated in crevices and holes. This interdependence highlights the interaction between the spheres in nature.How does each Fossil Fuel (coal, oil, & natural gas) affect the environment?
Answer:
When we burn oil, coal, and gas, we don't just meet our energy needs—we drive the current global warming crisis as well. Fossil fuels produce large quantities of carbon dioxide when burned. Carbon emissions trap heat in the atmosphere and lead to climate change.

How does homeostasis maintain a balance in an ecosystem?
Answer: It is known as ecological homeostasis to the exchange that takes place between diverse natural means that allow to maintain a balance within an ecosystem. These adjustments are considered necessary to achieve survival. Usually these homeostatic balances can be understood by observing populations or systems that depend on each other.
Explanation:
which target organ releases glucose into the blood-stream as a result of the action of adreline?
a) adrenal gland
b) kidney
c) liver
d) pancreas
The answer for this is the liver
The target organ that releases glucose into the bloodstream as a result of the action of adrenaline is the liver, which is present in Option C, as the liver stores the glucose in the form of glycogen.
What is the importance of glycogen in the body?Glycogen is a polysaccharide that is stored in the liver and muscles of the human body and plays a crucial role in maintaining the body's energy as well as glucose homeostasis. During exercise or physical activity, glycogen is broken down into glucose, which is then released into the blood as fuel; this is regulated by hormones such as insulin and glucagon and prevents hyperglycemia.
Hence, the target organ that releases glucose into the bloodstream as a result of the action of adrenaline is the liver, which is present in Option C, as the liver stores the glucose in the form of glycogen.

Phytopharmaceuticals are pharmaceutical compounds that are found in plants. They can be naturally occurring or a result of biotechnology. Recently, scientists created genetically modified (GM) corn that produces the antibiotic penicillin. The seeds of this GM corn contain a large amount of the antibiotic penicillin, making the cost of producing the penicillin much cheaper and making the method of delivering it to patients in need much easier. Given the benefits of this GM corn, which of the following may be a concern regarding its production?
A.The GM corn may develop infections from bacteria that are sensitive to the antibiotic.
B.The GM corn might pass resistant genes to other organisms, like birds, that may eat the seeds.
C.Because corn uses the wind for pollination, people allergic to penicillin may be at risk for exposure to the antibiotic in the air.
D.Increased availability of the antibiotic may increase the development of antibiotic resistance in the infectious agents penicillin is used to treat.
Answer:
The answer is D.Increased availability of the antibiotic may increase the development of antibiotic resistance in the infectious agents penicillin is used to treat.
Explanation:
The correct option is Increased availability of the antibiotic may increase the development of antibiotic resistance in the infectious agents penicillin is used to treat.
What are genetically modified crops?Through the use of laboratory procedures, genetic modification (GM) technology enables the transfer of genes for particular traits between species.
In the middle of the 1990s, GM crops were first made available in the U.S. The majority of GM crops being farmed in the U.S. have been modified to be herbicide or insect resistant. The three GM crops with the highest acreages are corn, soybeans, and cotton.
The technology has the potential to be used in the future to improve nutrition, stress tolerance, disease resistance, biofuel efficiency, and the cleanup of polluted places.
The U.S. Department of Agriculture (USDA), the Environmental Protection Agency (EPA), and the Food and Drug Administration (FDA), each with the ability to regulate particular parts of the crops, are in charge of regulating GM crops at the federal level.
Therefore, The correct option is Increased availability of the antibiotic may increase the development of antibiotic resistance in the infectious agents penicillin is used to treat.
