During the process of replication, a molecule of DNA unzips, forming two single strands what makes up each individual strand of DNA?
A( paired adenine and uracil bases
B( Paired thymine and guanine bases
C( sugar groups attached to individual amino acids
D( nitrogenous bases attached to a sugar- phosphate backbone
Answer:
D
Explanation:
A and B are wrong since the whole point of unzipping a DNA molecule is to separate the paired bases so replication can occur off of each template strand. C is incorrect since there are no amino acids in DNA strands. D would be the answer as that is just what the structure of DNA looks like

Which of the following statements about secondary succession is true?
Answer:
A
Explanation:
A. Secondary succession occurs in ecosystem that have no vegetation.
What is secondary succession?
"Secondary succession, type of ecological succession (the evolution of a biological community's ecological structure) in which plants and animals recolonize a habitat after a major disturbance—such as a devastating flood, wildfire, landslide, lava flow, or human activity."
What are the stages of secondary succession?
The stages that lead to secondary succession include:
Growth exists.Existing growth is destroyed.Destruction stops. The soil remains.Time goes by.Regrowth begins.Fast-growing plants and/or trees are dominant for a while.Slower growing plants and/or trees come back and begin growing.Eventually, the area is fully populated with plant life again, though it may be more diverse or otherwise different than it was prior to being destroyed.What is an ecosystem?
"An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life."
What is a vegetation?
"Vegetation is defined as growing plants, or a life without physical, mental or social activity."

Answer: DNA replication needs to occur because existing cells divide to produce new cells. So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions.
Explanation:
During cell division, a cell must replicate its DNA, and if there are errors Before a cell can divide, many processes must occur, including the proper Mitosis is the phase when the cell actually divides into two cells, known as daughter cells. giving replication enzymes access to create a new copy of each chromosome.

Which of the following descriptions of differences between eukaryotes and prokaryotes is NOT CORRECT? Group of answer choices Eukaryotes have ester-linked phospholipids, whereas prokaryotes have ether-linked or ester-linked phospholipids. Eukaryotic cell walls lack peptidoglycan in their cell walls (if present), whereas many prokaryotes use peptidoglycan in their cell walls. Eukaryotic cells have histones for DNA organization, whereas prokaryotic cells have histone-like proteins or nucleoid-associated proteins involved in DNA organization. Eukaryotic cells typically have circular chromosomes, whereas prokaryotic cells typically have linear chromosomes.
Answer:
Eukaryotic cells typically have circular chromosomes, whereas prokaryotic cells typically have linear chromosomes.
Explanation:
Prokaryotic and Eukaryotic cells are the two kinds of cells that living organisms are composed of. Eukaryotic cells are cells that possess a membrane-bound nucleus while prokaryotic cells do not possess a membrane-bound nucleus. The cell membrane of eukaryotes contain ester-linked phospholipids, whereas that of prokaryotes (bacteria and archeae) have ether-linked or ester-linked phospholipids.
Peptidoglycan is the major constituent of the cell wall of many prokaryotes (bacteria) while peptidoglycan is absent in the cell wall of eukaryotes that possess it. One notable difference between eukaryotic and prokaryotic cells is the SHAPE OF THEIR CHROMOSOME.
- The chromosome in eukaryotic cells is LINEAR while that in prokaryotic cells is CIRCULAR in shape.

How enzymes function in chemical reaction?
Answer:
Enzymes perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily.

Answer:
D: The trait of agouti fur is dominant over the trait of black fur.
Explanation:
A is not true because you can clearly see that there is a chance for the offspring to have black fur.
B is false because there is a 50% chance for the offspring to have agouti fur and 50% for black fur. If the trend keeps going, not all the mice would end up with black fur.
C can't be the answer because that just makes no sense. If you don't like my reasoning, neither do I. It just doesn't feel right.
What general effects on the earth’s ocean tides would result if
(a) the Moon’s mass were doubled,
(b) the distance between the earth and the Moon were ½
(c) the Earth had no Moon?
Answer:
The question isn't complete so the answers don't correlate? Or are they fill-in-the-blank answers?
Explanation:
If the Moon's mass were doubled, the ocean tides on Earth would be higher and more significant. If the distance between the Earth and the Moon were halved, the ocean tides would also be higher and more pronounced. Hence the correct option is B.
(a) If the Moon's mass were doubled, its gravitational pull on Earth would increase, leading to stronger tidal forces. This would result in higher and more powerful ocean tides. The increased gravitational attraction between the Earth and the Moon would cause larger tidal bulges, leading to more extreme high and low tides.
(b) If the distance between the Earth and the Moon were halved, the gravitational pull of the Moon on Earth would become significantly stronger. This would result in more substantial tidal forces, leading to higher amplitude tides. The closer proximity would create more significant tidal bulges, causing more pronounced high and low tides around the world.
(c) If the Earth had no Moon, there would still be ocean tides, but they would be much weaker compared to the present scenario. The Moon's gravitational pull is a primary driver of tides on Earth. Without the Moon's influence, the tides would primarily be influenced by the Sun's gravitational pull.
Hence the correct option is B.

In order for P. multocida to survive and carry out cellular functions (and cause infection), the energy contained in each molecule of glucose must be converted into ATP. This occurs via the process of chemiosmosis, which couples electron transport to ATP synthesis. This process involves the sequential transfer of elections via a series of protein complexes and carriers found in the bacterial plasma membrane. Recall that electrons move down the chain in a sequential fashion due to the increasing electronegativity of the components of the electron transport chain.
Arrange the components of the electron transport chain in order from least electronegative.
a. O2
b. NADH dehydrogenase
c. Cytochrome b-c1 complex
d. Coenzyme Q
e. Cytochrome c
f. Cytochrome oxidase complex
Answer:
Components of the electron transport chain (ordered by electronegativity from least electronegative to most electronegative):
NADH dehydrogenase >> Coenzyme Q >> Cytochrome b-c1 complex >> Cytochrome c >> Cytochrome oxidase complex > O2
Explanation:
The electron transport chain transfers electrons from donors to acceptors via redox reactions (i.e., where reduction and oxidation occur together), and couples the transfer of electrons with proton transfer (H+ ions) across the membrane. In the electron transport chain, the electrons are transferred from NADH dehydrogenase NADH to oxygen (O2) through a series of transmembrane complexes: NADH-Q oxidoreductase, Q-cytochrome c oxidoreductase and cytochrome c oxidase. In the first place, the reduced form of coenzyme Q (ubiquinone) transports the electrons from the NADH-Q oxidoreductase to the Q-cytochrome c oxidoreductase complex (Cytochrome b-c1 complex). Second, the cytochrome c transports the electrons from this complex (i.e., Cytochrome b-c1 complex) to the Cytochrome oxidase complex, this being the last component in the electron transport chain that is responsible to catalyze the reduction of O2.

How does propagation occur in DNA and RNA?
Answer:
Life on earth is very diverse, from single-celled protozoans to complex multicellular plants and animals. But at the molecular level, all life is fundamentally made up of the same building blocks – DNA and RNA. One of the primary differences between DNA and RNA is that DNA is double-stranded while RNA is single-stranded.

Jason wanted to find out how he could increase the number of popcorn kernels that pop when cooked. He hypothesized that more kernels would pop if he used more oil. To test this, he placed 100 kernels of “Pop Rite’ popcorn into a popcorn popper that contained different amounts of oil. He used the following amounts of oil: 5 ml, 10 ml, 20 ml, and 30ml. 5mL is the amount of oil suggested on the popcorn box. He conducted the test 3 times for each amount of oil. He then counted the number of kernels that had popped. Each time he heated the oil for 2 minutes and cooked the popcorn for 4 minutes.
