Compared to aerobic respiration, glycolysis produces _________ atp.
In anaerobic circumstances, pyruvate converts to lactate through anaerobic glycolysis. Anaerobic breath brings about the development of 2 ATP particles.
In oxygen-consuming circumstances, pyruvate enters the citrus extract cycle and goes through oxidative phosphorylation prompting the net creation of 32 ATP particles. Glycolysis (see "Glycolysis" idea) is an anaerobic interaction - it needn't bother with oxygen to continue. This interaction delivers an insignificant measure of ATP. The Krebs cycle and electron transport in all actuality do require oxygen to continue, and within the sight of oxygen, these interactions produce significantly more ATP than glycolysis alone.
This high creation happens because of the total breakdown of glucose into CO2 and Energy (ATP). In oxygen-consuming breath 38 ATP is delivered through in an anaerobic breath just 2 ATP is created with the development of an extra side item like lactic corrosive or ethanol.

If a bacterium adapted to a cold environment were moved to a much warmer environment; what changes to the membrane lipids should the bacterium make? A. Because increased temperature decreases fluidity, the bacterium should increase the length of fatty acid tails on membrane lipids B. Because increased temperature increases fluidity, the bacterium should decrease the length of fatty acid tails on membrane lipids C. Because increased temperature decreases fluidity, the bacterium should decrease the length of fatty acid tails on membrane lipids D. Because increased temperature increases fluidity, the bacterium should increase the length of fatty acid tails on membrane lipids
B. Because higher temperatures make things more fluid, the bacteria should shorten the fatty acid tail on their membrane lipids.
It is anticipated that the content of membrane lipids (phosphatidylcholine fatty acids) will change when the temperature drops in order to preserve homeoviscosity. Triacylglycerol fatty acids, which make up storage lipids, are anticipated to react to temperature changes similarly while having various functions. The fraction of saturated fats in membrane lipids increases noticeably when the ambient temperature rises, while the proportion for unsaturated or branched chain fats decreases simultaneously. Increased temperatures (up to about 40 oC) improve the rate of reaction by increasing the frequency of collisions between both the enzyme and the substrate, which changes how lipase works.

what would be the consequence if a cell were unable to replicate its dna
If a cell were unable to replicate its DNA, it would not be able to divide and produce two daughter cells with identical genetic material. This could have serious consequences for the organism as a whole.
For example, during development, cells need to divide and differentiate to form the various tissues and organs of the body. If DNA replication is impaired, the resulting daughter cells may not have the correct genetic material, leading to developmental abnormalities and possibly even death.
In adults, failure of DNA replication can lead to cancer. Mutations in genes that regulate DNA replication, such as tumor suppressor genes, can result in uncontrolled cell division and the formation of tumors.
In short, the ability to replicate DNA is essential for normal cellular function, growth, and development, and any impairment of this process can have significant consequences for the organism.

Results from a single locus can prove someone is NOT the father of a certain child.
Select one:
a. True
b. False
True. The results from a single locus, or a single genetic marker, can prove that someone is not the father of a certain child, but cannot definitively prove that they are the father.
This is because the inheritance of genetic markers is complex, and a match at a single locus does not necessarily mean that two individuals are related.
However, a mismatch at a single locus is sufficient evidence to exclude paternity. When a child is born, they inherit one set of genetic markers from each biological parent. If the genetic marker at a particular locus in the child does not match the genetic marker of the alleged father, then it is certain that the alleged father is not the biological father of the child.
To conclusively establish paternity, a DNA paternity test typically uses multiple genetic markers to achieve a high degree of accuracy. This involves comparing the child's DNA to that of the alleged father, as well as that of the biological mother, to determine the probability of paternity.

Is AA heterozygous recessive or dominant?
AA is typically used to represent a homozygous dominant genotype, in which an individual has two copies of a dominant allele.
Heterozygous genotype, in which an individual has one copy of a dominant allele and one copy of a recessive allele, the answer would depend on the specific trait being considered.
For some traits, the dominant allele may be completely dominant over the recessive allele, meaning that even if an individual has only one copy of the dominant allele, the dominant phenotype will be expressed. In this case, the heterozygous genotype would be considered dominant.
For other traits, the dominant allele may be only partially dominant over the recessive allele, meaning that the phenotype of the heterozygous individual may be intermediate between the two homozygous genotypes. In this case, the heterozygous genotype may be considered incompletely dominant or codominant.

Cyanobacteria (also known as blue-green algae) are a group of photosynthetic bacteria that are found in a wide range of habitats, including freshwater, marine, and terrestrial environments. They are some of the oldest known organisms on Earth, with fossil evidence dating back over 3 billion years.Cyanobacteria are unique among bacteria in that they have the ability to carry out oxygenic photosynthesis, a process that uses sunlight to generate energy and produces oxygen as a byproduct. This process is similar to the photosynthesis carried out by plants and is thought to have played a crucial role in the evolution of life on Earth by generating oxygen in the atmosphere.In terms of their evolutionary relationships with other prokaryotic groups, cyanobacteria are classified within the domain Bacteria, and are thought to be closely related to other photosynthetic bacteria such as the Chlorobi and Chloroflexi. However, the precise relationships between these groups are still the subject of ongoing research and debate among scientists, and the exact branching patterns of their evolutionary history may vary depending on the specific phylogenetic analysis being performed.
In summary, while cyanobacteria are believed to be one of the earliest and most important groups of prokaryotes in the evolutionary history of life on Earth, the specific details of their relationships with other prokaryotic groups may vary depending on the specific phylogenetic analysis being performed.

how many generations does it take to develop a new plant species by polyploidy
With the formation of unreduced gametes or doubled somatic cells, polyploidy can yield the antecedents of new species inside one generation (autopolyploidy) as well as two generations (allopolyploidy) (Ramsey and Schemske, 1998; Mason and Pires, 2015).
In just one or two generations, fully separated polyploid species can appear, and in as little as 60 generations, diploid and homoploid hybrid species can reach isolation.
In some circumstances, polyploids can be employed as a bridge enabling gene transfer between two species when crossing between them is not feasible due to differences in ploidy level. Moreover, polyploidy frequently causes meiotic mistakes that impair fertility, enabling the development of seedless cultivars. According to some estimations, between 30 and 80 percent of species of live plants are polyploid.

mr. mb’s red skin indicated his temperature control center was trying to:
Mr. MB's red skin indicates that his temperature control center was trying to regulate his body temperature by increasing blood flow to the skin's surface, a process known as vasodilation.
When the body's temperature rises above the normal range, the hypothalamus, a region of the brain responsible for regulating body temperature, triggers a series of responses to restore the body's equilibrium.
One of these responses is vasodilation, which causes the blood vessels in the skin to widen, allowing more blood to flow to the skin's surface. This process increases heat loss from the body through radiation and convection, helping to cool the body.
Vasodilation can also cause the skin to appear red, as more blood is visible through the skin's surface. Conversely, when the body's temperature drops below the normal range, the hypothalamus triggers vasoconstriction, narrowing the blood vessels in the skin to reduce heat loss and conserve heat.

how is it possible for one species to produce many other species?
Natural selection offers a explanation for how the genetic characteristics of a species may change through time. This might lead to speciation, or the emergence of new, distinct species.
The species sometimes exists in two (or more) populations, and thus inhibits interbreeding between them. When maintained apart for a long enough time and exposed to a wide enough array of environmental conditions, each population takes its own distinct evolutionary path. New species are produced by speciation, which happens when an ancestor population splits into two or more genetically distinct descendant populations. The process of speciation involves the separation of groups from the original population and the emergence of genetic differences between the two groups. A population is a group of people who are all related.
