Answer:
I think that DNA is like genetics, you share genetics (or you can call it DNA) with your family members, It's the genetic code that determines all the characteristics of a living thing. Basically, your DNA is what makes you, you! Each nucleotide contains a sugar and a phosphate molecule, which make up the 'backbone' of DNA, and, one of four organic bases.
Explanation:
Genetics is the branch of biology that involves the study of how different traits are transmitted from one generation to the next.
O True
O False
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:
Answer:
One of the key molecules in DNA replication is the enzyme DNA polymerase. DNA polymerases are responsible for synthesizing DNA: they add nucleotides one by one to the growing DNA chain, incorporating only those that are complementary to the template.

Tay-Sachs disease is a genetic disorder that results in the destruction of neurons due to a buildup of sphingolipids in the cells. Which organelle is malfunctioning in Tay-Sachs
Answer:
Lysosomes
Explanation:
Tay-sachs disease is a rare Autosomal recessive disease that causes neurodegenerative disorder.
Deficiency of an enzyme Hexosaminidase A results in excessive accumulation of gangliosides (sialic acid containing glycosphingolipids) in the brain and nerve cells.
It is a lysosomal storage disease .Absence of the enzyme Hexosaminidase A ,that breakdowns substance like fats results in accumulation of such substance in the lysosomes.Too much accumulation of fats in the lysosomes destroy the cell.
Which statement is true of recessive sex-linked traits such as color blindness ?
Answer:
colorblidness is carried on the X cromasome. since it is resessive it can be covered up. woman have 2 X cromasomes so both have to have it or she wont be color blind. men only have one X cromasome so its more likely that their just one X can have it
Explanation:
Answer:
Ressesive
Explanation:
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.HELP!! ASAP!! PLEASE!!

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.

Alicia is moving from southern Georgia to Alaska. She wants to bring her peanut plants with her so she can replant them in Alaska. Which best explains how
this could affect the survival of her peanut plants?
O A Alicia's peanut plants will not be affected by the move from southern Georgia to Alaska because the environmental conditions are the same.
o B. Alicia's peanut plants are not suited for the environmental conditions in Alaska, which would threaten their survival.
C. Alicia's peanut plants will grow larger by the move from southern Georgia to Alaska because the environmental conditions are better.
OD. Alicia's peanut plants are better suited for the environmental conditions in Alaska, which would improve their survival

this phenomenon, which provides evidence for the big bang theory, is called what?
Answer:
Doppler Red-Shift Evidence
Explanation:
The Doppler red-shift of light observed from distant stars and galaxies gives evidence that the universe is expanding (moving away from a central point). This allows for Big Bang Theory, because after a “bang” occurs all of the matter moves away from the point of origin.
What is tissue? Include examples for both plants and animals.
Answer:Plants are simpler organisms than animals, having three organ systems and fewer organs than do vertebrate animals. Organs are composed of tissues, which are in turn composed of cells. Plants have three tissue types: ground, dermal, and vascular. Animals have four: epithelial, connective, muscle, and bone.
Explanation:
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.
