Together, glycolysis, the Krebs cycle, and the electron transport chain release about __________________________ per molecule of glucose.
Answers
Together, glycolysis, the Krebs cycle, and the electron transport chain release about 38 ATP molecules per molecule of glucose.
Together, glycolysis, the Krebs cycle, and the electron transport chain release about 38 ATP molecules per molecule of glucose. Glycolysis is the first step in the process of cellular respiration and breaks down glucose into two pyruvate molecules, producing a net of 2 ATP molecules. The Krebs cycle, also known as the citric acid cycle, takes place in the mitochondrial matrix and produces 2 ATP molecules, 6 NADH molecules, and 2 FADH2 molecules per glucose molecule. The electron transport chain then uses the NADH and FADH2 molecules to generate a proton gradient across the inner mitochondrial membrane, which drives the synthesis of ATP via oxidative phosphorylation. Overall, this process produces 34 ATP molecules per glucose molecule, bringing the total to 38 ATP molecules when combined with the 2 ATP molecules produced in glycolysis.

how many amino acids would be coded from a sequence of 27 nucleotides given thaat the sequence codes for one stop codon
Answers
Each amino acid is represented by a three-letter genetic word called a codon, which is written in a commaless fashion. As a result, 24 bases would result in 24/3 = 8 codons/words. As a result, a DNA containing 24 bases would code for an 8-amino acid protein.
How many nucleotides do 50 amino acids require?Cistron is a DNA segment that codes for a single polypeptide. If the polypeptide has 50 amino acids, the cistron must include at least 51 codons (50 codons for amino acids and 1 codon is the stop codon). Because each codon is a triplet, the minimal length of the cistron for 50 amino acids is 51 x 3 = 153 bp (base pairs).

generally, will natural selection result in an increase or decrease in variation? why does this happen and how, in theory, will it affect evolution in the future?
Answers
Natural selection decreases the genetic variation in populations by selecting for or against a specific gene or gene combination
How does natural selection cause variation?Genetic variations that alter gene activity introduce different traits in an organism. If a trait is advantageous and helps the individual survive and reproduce, then genetic variation is more likely to be passed on to the next generation, which is known as natural selection.
As natural selection is a mechanism of evolution, organisms that are more adapted to environment are more likely to survive and pass on the genes that aided their success. Therefore, this process causes species to change and diverge over time.

at what age does your brain reach 90 percent of its adult weight?
Answers
Answer: Age 5.
Explanation: Incredibly, it doubles in size in the first year. It keeps growing to about 80% of adult size by age 3 and 90% – nearly full grown – by age 5. The brain is the command center of the human body.
According to neuroscience, the human brain reaches 90 percent of its adult weight at around the age of six years.
Although the brain remains to grow for several years, the vast majority of its growth occurs in the first few years of life. The growth of the brain takes place more in terms of development than in size. The increase in brain size in the early years of life is mostly because of the growth of neural connections. A child's brain continues to develop and grow over time and adolescence, however, the pace of growth decreases with age as the number of neural connections reduces.
In the first two years of life, the brain doubles in size and continues to grow rapidly until about the age of six years. The brain reaches almost its full adult size by the time a person is six years old. However, the neural connections in the brain continue to develop throughout life as the brain experiences new things and learns new skills. Thus, the human brain never stops changing, and it is capable of growing and adapting throughout the individual's lifespan.

changes in body size or beak shape to avoid competition with another similar species is termed:
Answers
The phenomenon of changes in body size or beak shape to avoid competition with another similar species is known as character displacement.
This process occurs when two species that occupy similar niches in an ecosystem compete for resources. Over time, natural selection favors individuals within each species that have traits that allow them to use different resources or occupy slightly different habitats, reducing competition between the two species. One common outcome of character displacement is a divergence in body size or beak shape between the two species, which allows them to more efficiently utilize different resources in their shared environment. This can ultimately lead to the formation of new species over long periods of time. Character displacement is an important mechanism in evolutionary biology and is one example of how competition between species can drive adaptive changes.

Due to the fact that they were passed down from a common ancestor, homologous structures are those that are comparable in related animals.
Characteristics that resemble one another because of a common ancestor are known as homologous features. These characteristics may change in look and function as species adapt in their habitats and develop over time, but eventually they still retain the structure, DNA, or embryonic framework of their common origin. While comparable structures demonstrate that similar evolutionary forces can result in similar adaptations, homologous structures suggest that they have a common ancestor (beneficial features). The relationship between species can be inferred from similarities and differences in biological molecules (such as those found in the DNA gene sequence). Homologous structures show that the species are related via evolution and have a common ancestor.

Answers
b) The response to the signal would persist longer after activation. Phosphatases are enzymes that remove phosphate groups from proteins, and thus play a key role in regulating the activity of signaling pathways.
If phosphatases have reduced levels of function, this would result in a reduction in the rate at which signaling proteins are deactivated, causing the response to persist for a longer time after activation.
This would result in a longer response to the signal compared to normal function of the phosphatases.

what immune cells are the first line of defense for gingival bac /disease
Answers
The first line of defense against gingival bacteria or disease are the innate immune cells. These include neutrophils, macrophages, dendritic cells, and natural killer cells.
Neutrophils are the most abundant white blood cells in the body and play a crucial role in the early response to bacterial infection. They are recruited to the site of infection within minutes and engulf and kill the invading bacteria.
Macrophages are also present in the gingival tissue and function as the second line of defense against gingival bacteria. They engulf and digest the bacteria, produce cytokines that activate other immune cells, and promote tissue repair. Dendritic cells are specialized immune cells that capture and present antigens to other immune cells, activating an immune response against the invading bacteria.
Natural killer cells, on the other hand, are involved in the innate immune response against viruses and cancer cells, but can also play a role in the early response to bacterial infection. They recognize and kill infected cells, limiting the spread of infection.
Overall, the innate immune cells play a critical role in the early response to gingival bacteria or disease, providing a first line of defense before the adaptive immune response kicks in.
