Answers
A single sugar phosphate chain with nitrogenous bases attached along it describes a molecule of the molecule being described is DNA, which stands for Deoxyribonucleic acid.
DNA is a macromolecule that carries genetic information in living organisms. It consists of a long, helical double-stranded structure formed by two sugar phosphate chains with nitrogenous bases attached along them. The sugar in DNA is deoxyribose, which forms the backbone of the molecule together with phosphate groups. Alternating sugar and phosphate units create a strong and stable structure. The nitrogenous bases, adenine (A), thymine (T), guanine (G), and cytosine (C), are attached to the sugar molecules. These bases form specific pairs: A pairs with T, and G pairs with C, through hydrogen bonding. This complementary base pairing is vital for DNA's ability to store and transmit genetic information. The sequence of nitrogenous bases along the sugar phosphate chain carries the genetic code. It provides instructions for the synthesis of proteins and regulates various cellular processes. DNA's unique structure and base pairing enable the faithful replication of genetic information during cell division and the transmission of traits from one generation to the next. Overall, the single sugar phosphate chain with nitrogenous bases attached along it describes the fundamental structure of DNA, the molecule responsible for heredity and the storage of genetic information in living organisms.

Answers
Answer:
A. Enzymes break the hydrogen bonds between the nitrogenous bases to separate the two strands of DNA.
Explanation:
DNA replication involves several different enzymes. Enzymes break the hydrogen bonds between the nitrogenous bases to separate the two strands of the DNA molecule. Then an enzyme called DNA polymerase joins individual nucleotides together to form the new complementary strands of DNA. Lastly, the DNA polymerase "proofreads" each new strand to make sure that each DNA molecule is perfect, or a nearly perfect copy of the original molecule.

Answer:
The correct answer is (A.) Enzymes break the hydrogen bonds between the nitrogenous bases to separate the two strands of DNA.
Explanation:
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.

all amino acid based hormones are lipid soluble and can cross the plasma membrane.T/F?
Answers
False all amino acid based hormones are lipid soluble and can cross the plasma membrane.
Not all amino acid based hormones are lipid soluble and can cross the plasma membrane. In fact, there are two types of amino acid based hormones - those that are lipid soluble and those that are not. The lipid soluble ones include thyroid hormones and steroid hormones, while the non-lipid soluble ones include most of the other amino acid based hormones such as insulin and growth hormone. These non-lipid soluble hormones require specific receptors on the cell surface to be able to exert their effects, while lipid soluble hormones can directly enter the cell and bind to intracellular receptors. Therefore, it is important to note that not all amino acid based hormones are able to cross the plasma membrane.
Amino acid based hormones are a type of signaling molecule that are derived from amino acids and are important in regulating various physiological processes in the body. While some of these hormones are lipid soluble and can cross the plasma membrane, not all of them are able to do so. This means that they require specific receptors on the cell surface to be able to exert their effects. It is important to understand the differences between these two types of amino acid based hormones and how they function in the body.

william created the diagram below to help him understand how DNA contains instructions to create proteins. Which of the following best identified what processes are labeled as x and y above?
Answers
DNA contains the genetic instructions for all living organisms in the form of a code made up of four chemical bases: adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair up in a specific way (A with T, and C with G) to form the rungs of the DNA ladder. The sequence of these base pairs determines the genetic information that is stored in DNA.
How DNA contains instructions to create proteins?This genetic information is used to create proteins, which are essential for the structure and function of cells. The process of creating proteins from DNA is called protein synthesis. It occurs in two main steps: transcription and translation.
During transcription, a section of DNA is copied into a molecule of messenger RNA (mRNA) by an enzyme called RNA polymerase. The mRNA then leaves the nucleus and moves to the ribosomes, which are the site of protein synthesis.
During translation, the sequence of bases in the mRNA is read by transfer RNA (tRNA) molecules, which bring the correct amino acids to the ribosome. The amino acids are then linked together in a specific order, determined by the sequence of bases in the mRNA, to form a protein.
So, to summarize, DNA provides the instructions for making proteins through a process called protein synthesis, which involves transcription of a specific sequence of DNA into RNA, and translation of the RNA sequence into a specific sequence of amino acids that constitute a protein.
Note that a summary was given as the information is incomplete and the complete question wasn't found.

what three major lines of evidence did charles darwin use to argue that species have changed over time?
Answers
Answer:fossil evidence, biogeographical evidence, and anatomical evidence.
Explanation:
Charles Darwin used fossil records, biogeography, and homologous structures to argue that species have changed over time.
Explanation:Charles Darwin used three major lines of evidence to argue that species have changed over time:
Fossil Record: Darwin compared the fossils of different species, noting similarities and differences. He observed that fossilized organisms in older rock layers were simpler and differed more from present-day species compared to the organisms found in younger rock layers.Biogeography: Darwin observed that organisms on different continents shared similarities in their characteristics, suggesting that they had a common ancestor. He also noted that similar habitats on different continents were filled with different but closely related species.Homologous Structures: Darwin observed that different species had similar structures, such as the arm bones of a human and the wing bones of a bat. These similarities suggested a common ancestor.These three lines of evidence helped Darwin develop his theory of evolution by natural selection.

We learned from our notes, 3.2 Slide 4 that there are 2 different types of Cellular Respiration:
1. Cellular Respiration (Aerobic): C6H12O6 + 602 ----> 6CO2 + 6H2O +36ATP
2. Fermentation (Anaerobic): C6H12O6 --> 2C2H5OH + 2CO2 + 2ATP
Aerobic & Anaerobic both create CO2, but only Aerobic has oxygen (O2). So where does the CO2 come from?
Cellular Respiration (Aerobic) has Oxygen and Anaerobic does not. What does the Oxygen mostly reform to
create?
Answers
Following glycolysis, pyruvic acid undergoes oxidative decarboxylation, in which each molecule of the three-carbon acid is changed into a two-carbon acetyl CoA molecule and a carbon dioxide molecule is produced.
Cellular respiration can occur either anaerobically (without oxygen) or aerobically (with oxygen) (without oxygen). When cells respire aerobically, glucose and oxygen combine to produce ATP, which the cell may use.
How crucial is oxygen to both aerobic and anaerobic respiration?In order to carry out aerobic cellular respiration, aerobic cells and organisms require oxygen. With oxygen serving as the last electron acceptor in the electron transport chain, the hydrogen ion gradient required for ATP synthase operation may be produced.
When there is oxygen present, aerobic respiration takes place, but anaerobic respiration does not. Anaerobic respiration generates alcohol, whereas aerobic respiration generates carbon dioxide and water as waste products.

No, the structure of pancreatic lipase is not the same as gastric (produced in the stomach) lipase.
In the field of science, we can describe lipases as enzymes that are actively involved in the breaking of fats.
There are three sites in the human body where lipase enzyme is produced. These sites are serous glands, pancreas and stomach. However, the lipase produced by each of these glands or organs is different because each lipase has to function in a different environment. Hence, they are produced in order of the place where they are to function.
