The backbone of the DNA molecule is composed of sugar and phosphate groups. These components are connected by phosphodiester bonds, which alternate to form a long chain.
The correct answers to the question “Select the parts that make up the backbone of the DNA molecule” are a. Sugar and d. Phosphate. Sugar (deoxyribose) and phosphate molecules are the two primary components of the DNA backbone. The sugar and phosphate molecules alternate to form the long chain that makes up the backbone. The nitrogenous base, which is bonded to the sugar, extends away from the backbone and pairs with its complementary base on the opposite strand to form the DNA molecule's double helix structure. Nucleoside is a combination of a sugar molecule (ribose or deoxyribose) and a nitrogenous base. These components are used to create nucleotides. Glycine is an amino acid, which is a component of proteins, not DNA. The nitrogenous base is bonded to the sugar and extends away from the backbone, as mentioned above. However, it is not a component of the backbone itself, so it is not a correct answer to this question.

If conditions are not restore to optimal conditions, the enzymes of the body do not function correctly because they are denatured, potentially leading to organ failure and possible death.
The term "denatured" is used to describe the condition of an enzyme that is unable to function properly. When an enzyme becomes denatured, it loses its structure and shape, which causes it to be unable to perform its intended function. This can happen due to a number of different factors, such as changes in temperature or pH levels. When an enzyme becomes denatured, it is unable to interact with the substrate that it is supposed to act on. As a result, the chemical reaction that the enzyme is supposed to catalyze cannot occur. This can lead to a number of different problems within the body, such as organ failure or even death, in extreme cases.
Therefore, it is very important to maintain optimal conditions for enzymes to function properly in the body. Denatured enzymes are unable to carry out their designated chemical reactions, and this can have drastic consequences on the body's metabolic processes.

Who are the 2 scientists that influenced Darwin's theory of evolution?
The two scientists that influenced Darwin's theory of evolution are Thomas Malthus and Charles Lyell.
Evolution is defined as the process of gradual development or changes of an organism's features over time as a result of changes in genetic and environmental factors. The theory of evolution, as proposed by Charles Darwin, is the most widely recognized scientific theory that explains how organisms change and adapt to their surroundings.The theory of evolution proposes that all species on Earth have evolved from a single common ancestor through a process of natural selection. According to Darwin's theory of evolution, organisms that possess favorable characteristics for their environment are more likely to survive and pass on those characteristics to their offspring. Those organisms that are less well-suited to their environment will not survive and their traits will eventually be lost over time.In the development of his theory, Darwin was influenced by the works of several scientists including Thomas Malthus and Charles Lyell. Darwin incorporated their ideas into his own to produce the theory of evolution. Malthus argued that human population growth was limited by food supply, and this idea provided Darwin with the concept of natural selection. Lyell's work in geology proposed that the Earth's surface has been shaped over a long period of time by gradual processes, and this helped Darwin to understand the concept of slow changes in species over time.Learn more about Darwin's theory of evolution: https://brainly.com/question/1589147

Baby Jessica's parents respond to her every need as soon as she cries. Freud would predict that, as an adult, Jessica will be passive.The correct answer is c.
According to Freud's psychoanalytic theory, a child's first relationships are with its mother, and it is in these relationships that the ego emerges. The id, ego, and superego are the three components of the mind (conscious and unconscious) that have an impact on behavior.
The id is the instinctual side of the psyche that is driven by the need for immediate gratification, while the ego is the logical side of the psyche that helps to mediate the conflict between the id and the superego.The parents of Baby Jessica's are providing her with immediate gratification by responding to her every need as soon as she cries.
Freud would predict that Jessica would be passive as an adult because she would not be learning how to delay gratification, which is a critical skill for developing a healthy ego. Delaying gratification involves recognizing that immediate gratification may not be the best course of action in the long term.
In conclusion, Baby Jessica's parents respond to her every need as soon as she cries. Freud would predict that Jessica would be passive as an adult because she would not be learning how to delay gratification, which is a critical skill for developing a healthy ego.

What is the pair of chromosomes inherited from the mother and the other pair from the father?
A pair of chromosomes inherited from the mother and the other pair from the father is called a homologous chromosome pair.
Homologous chromosomes are similar in size, shape, and gene content and carry the same genes at the same loci, although the specific alleles may differ. In humans, the homologous chromosome pairs form the 23 pairs of chromosomes that contain the genetic material necessary for the development and functioning of the organism.
During sexual reproduction, each parent contributes one set of chromosomes, including one member of each homologous chromosome pair, to their offspring. The process of meiosis ensures that each gamete receives one member of each homologous pair, resulting in genetic diversity in the offspring.
This means that the genetic material inherited from the mother and father are combined in their offspring, leading to genetic variation within a population. The study of homologous chromosomes is essential for understanding genetics, inheritance patterns, and evolutionary biology.

who is known as the father of taxonomy, who developed our modern system of naming organisms?
Why is fermentation a required pathway for providing cellular energy when oxygen is unavailable or in insufficient supply? NAD is not regenerated by the electron transport chain. ATP production requires oxygen. NADH cannot be reduced to NAD Cells need either lactic acid or ethanol when oxygen is low, Lactic acid or ethanol can be used to generate oxygen.
Fermentation is a crucial pathway for providing cellular energy when oxygen is unavailable or in insufficient supply, as it allows cells to continue generating ATP by regenerating NAD+ and allowing glycolysis to continue.
Because it enables the regeneration of the oxidized form of the electron transport molecule NAD+, which is necessary for glycolysis to proceed, fermentation is a necessary mechanism for supplying cellular energy when oxygen is missing or in inadequate supply. Pyruvate is produced from glucose during glycolysis, and NAD+ is reduced to NADH. The electron transport chain's ability to convert NADH back into NAD+ in the presence of oxygen permits glycolysis to continue creating ATP. The electron transport chain, on the other hand, is unable to work when oxygen is lacking or insufficiently present, and NADH builds up, which can inhibit glycolysis.
By oxidizing NADH back to NAD during fermentation, NAD+ can be replenished, allowing glycolysis to continue generating ATP. Certain cells, like muscle cells and some microbes, can employ fermentation to make lactic acid or ethanol as end products in the absence of oxygen, allowing them to generate ATP without the need for oxygen.

What is a similar structure in different species that evolved separately called?
The similar structure in different species that evolved separately is called a convergent structure.
The term “convergent structure” refers to the process by which distinct species with different ancestors develop similar structures, either through adaptation to similar environmental conditions or similar ecological roles.
This phenomenon, known as convergent evolution, typically results in different organisms developing similar adaptations to solve the same problem.
Both structures have evolved to perform the same task (flight), and both have independently evolved to do so due to selective pressure in a specific habitat.
A similar structure, shared by different species, is termed homology when it is derived from a common ancestor, and analogy when it is not.
The similarity between bat wings and bird wings is a classic example of analogy, since these structures did not evolve from a common ancestral structure but instead emerged independently in response to selective pressure.

dna choose... joins choose... to synthesize a new choose... dna strand.
DNA polymerase is an enzyme that joins nucleotides to synthesize a new DNA strand during DNA replication.
The process begins with the separation of the double-stranded DNA molecule into two separate strands by an enzyme called helicase. One of the strands serves as a template for the synthesis of a new complementary strand. DNA polymerase reads the template strand and matches complementary nucleotides to it, adding them one by one in the 5' to 3' direction.
As each nucleotide is added, DNA polymerase catalyzes the formation of a phosphodiester bond between the 3' end of the growing DNA strand and the 5' phosphate group of the new nucleotide. This process continues until a complete new DNA strand has been synthesized.

Which of the following molecules is the lowest-energy donor of electrons to the electron transport chain?
A. NADH
B. water
C. FADH2
D. ATP
The molecule that is the lowest-energy donor of electrons to the electron transport chain is FADH2.
What is the electron transport chain? The electron transport chain (ETC) is a sequence of electron carriers in the inner mitochondrial membrane that facilitate the generation of ATP via oxidative phosphorylation. The final electron acceptor in the electron transport chain is oxygen.
NADH and FADH2 are important electron donors to the electron transport chain. They donate electrons to complex I (NADH) and complex II (FADH2), respectively, which then transfer them through the electron transport chain to complex IV, where oxygen is the final electron acceptor.
The energy produced by electron transfer is used to pump protons across the inner mitochondrial membrane, forming a proton gradient that drives ATP synthesis via ATP synthase. Therefore, NADH and FADH2 are important contributors to ATP synthesis via oxidative phosphorylation.
What is FADH2? FADH2 is a type of reduced flavin adenine dinucleotide (FAD), a cofactor involved in redox reactions in cells. FADH2 is created when FAD accepts two electrons and two protons. FADH2 is a substrate for succinate dehydrogenase (complex II) in the electron transport chain, where it donates electrons to the chain via its flavin group.
Since the reduction potential of FADH2 is lower than that of NADH, fewer protons are pumped across the mitochondrial membrane when FADH2 donates electrons to the chain. Therefore, NADH donates more energy to the electron transport chain than FADH2 does.
