In DNA Replication, ATTTGC is complementary to TAAACG. True or False?
Answers
Answer:
True.
Explanation:
It's commonly known that adenine pairs with thymine and guanine pairs with cytosine following complementary base pairing.
The statement "In DNA Replication, ATTTGC is complementary to TAAACG" is definitely true.
What is DNA replication?DNA replication may be defined as the biological process through which two identical replicas of DNA are formed from one original DNA molecule. It occurs in all living organisms acting as the most essential part of biological inheritance.
The process of DNA replication is commonly known for some complementary sequences. For example, adenine pairs with thymine, and guanine pairs with cytosine which effectively follows the process of complementary base pairing.
This base pairing of nucleotides will follow Chargaff's rule which states that the amount of adenine is always equal to the amount of thymine, while the amount of guanine always equal to the amount of cytosine.
Therefore, the statement "In DNA Replication, ATTTGC is complementary to TAAACG" is definitely true.

(5 Points)
carbohydrates & lipids
carbohydrates & proteins
proteins & nucleic acids
nucleic acids & lipids
Answers
Answer:
The most correct option is carbohydrates & lipids
Explanation:
Carbohydrates are organic compounds that contain carbon, hydrogen and oxygen [for example starch, (C₆H₁₀O₅)ₙ] while lipids generally contains carbon, hydrogen and oxygen [for example fatty acid, CH₃(CH₂)ₙCOOH] but could also contain other elements like sulphur and phosphorus.
Proteins are made up of building blocks called amino acids. Amino acids are made up of an amino group which consist of nitrogen and hydrogen. Hence, proteins have a large number of nitrogen atoms thus not part of the answer.
Nucleic acids are composed of nitrogenous bases and phosphate groups and are also not part of the answer for this reason.

Answers
A pelican with excellent eyesight has the ability to spot fish in water from above, diving down to catch them.
A pelican is a water bird that has evolved to be able to dive into the water to catch fish. Pelicans are known for their large bills, which they use to scoop up fish from the water. A pelican with excellent eyesight has the ability to spot fish in water from above, diving down to catch them.
Pelicans have a unique set of adaptations that allow them to spot fish from above the water's surface. Pelicans have large eyes that are well-suited to detecting movement, which is essential for spotting fish in the water. They also have the ability to adjust the lenses in their eyes to focus on objects both in the air and underwater
.Their keen eyesight and keen sense of hearing make them excellent hunters, and they are known for their ability to spot fish even in murky water.
Once a pelican spots a fish, it will fold its wings and dive headfirst into the water to catch it. Pelicans can hold their breath for up to a minute while they dive underwater to catch fish, and they can swallow their prey whole. Pelicans are fascinating birds that have a unique set of adaptations that allow them to thrive in their aquatic habitat.

Why is NAD+ so important if the cell takes the anaerobic pathway, so glycolysis to fermentation? Does the atp made in glycolysis depend on the NAD+ conversion to NADH in the first step? I am confused on why NAD+ is so important to atp production
Answers
Answer:
NAD+ (nicotinamide adenine dinucleotide) is indeed crucial for ATP production, even in anaerobic pathways such as glycolysis followed by fermentation. Allow me to explain the significance of NAD+ and its role in ATP production.
During glycolysis, glucose is broken down into pyruvate, producing a small amount of ATP and NADH. The conversion of NAD+ to NADH occurs during the oxidation of certain molecules, including glucose, in the pathway. This conversion is essential because NADH carries high-energy electrons that can be used in subsequent steps to generate more ATP.
In aerobic respiration, NADH is further utilized in the electron transport chain (ETC) within the mitochondria. The ETC transfers electrons from NADH to oxygen, generating a significant amount of ATP through oxidative phosphorylation. However, in anaerobic conditions where oxygen is limited, like during fermentation, the ETC cannot function.
Here's where NAD+ becomes critical. In order to keep glycolysis running and continue generating ATP, the NADH produced during glycolysis must be converted back to NAD+. This allows glycolysis to continue producing ATP, even without the presence of oxygen. Without a mechanism to regenerate NAD+, glycolysis would halt due to a lack of NAD+, leading to a severe reduction in ATP production.
Fermentation pathways differ depending on the organism, but they all involve the regeneration of NAD+. For example, in lactic acid fermentation, pyruvate is converted into lactate, which involves the transfer of electrons from NADH to pyruvate, regenerating NAD+. Similarly, in alcoholic fermentation, pyruvate is converted into ethanol, again regenerating NAD+.
In summary, NAD+ is essential in anaerobic ATP production because it serves as a coenzyme that accepts electrons and facilitates the conversion of NADH back to NAD+. By regenerating NAD+, cells can sustain glycolysis and continue producing ATP, even in the absence of oxygen.

1. Briefly describe the process of the dehydration synthesis for carbohydrates illustrated above:
2. Briefly describe the process of the hydrolysis reaction for carbohydrates illustrated above:
Answers
Explanation:
Dehydration Synthesis : Two monosaccharides (simple sugars) are joined together to form a disaccharide (double sugar) molecule. During this reaction, a molecule of water is removed, and a covalent bond is formed between the two monosaccharides. One monosaccharide loses a hydroxide group (-OH) from its carbon atom, while the other monosaccharide loses a hydrogen ion (H+), and the two react to form a covalent bond between the two carbon atoms. This process requires energy to occur.
Hydrolysis : Opposite process of dehydration synthesis, and it is the chemical reaction by which a disaccharide is broken down into two monosaccharides. During hydrolysis, a molecule of water is added to the disaccharide, causing the covalent bond between the two monosaccharides to break. One monosaccharide molecule gains a hydroxide group (-OH), while the other gains a hydrogen ion (H+), which were previously lost during dehydration synthesis. This process releases energy in the form of ATP

It experiences the first day of autumn at Position 1 and first day of spring at Position 3.
Answers
The correct statement about Australia is ; It experiences the first day of summer at Position 1 and first day of winter at Position 3.
The southern and northern hemisphere experiences winter and summer at different times of the year because the Earth's axis remains fixed ( almost ) when it orbits around the sun. therefore during the different orbit phases either the northern hemisphere or southern hemisphere faces/leans towards the sun.
The part of the earth ( hemisphere) that faces the sun will experience its first day of Summer while the hemisphere that leans away from the sun will experience its first day of winter.
Hence from the diagram we conclude that Australia been in the southern hemisphere will experiences the first day of summer at Position 1 and first day of winter at Position 3.
