What is an oxygen debt? How is it repaid? Explain in detail.
Answer:
oxygen debt a state that arises in very active muscles when insufficient oxygen is supplied by the lungs, causing the muscle tissue to respire anaerobically with the production of LACTIC ACID. When muscular activities slow down, the rate and depth of breathing remains at a high level until the lactic acid has been oxidized. an oxygen debt can be repayed by breathing heavily

When the blood glucose level decreases during a fast or between meals, the pancreas releases glucagon. Glucagon signals the liver to stop consuming glucose and to start producing glucose. Select the statements that describe how glucagon activates glucose production in the liver.
Answer:
Glucagon signals the liver to start producing glucose.
Explanation:
Glucagon signals the liver to start producing glucose from the breakdown of amino acids through gluconeogenesis process. When the glucose level decreases in the body due to fasting or starvation, the pancreas release glucagon which provides signals to the liver to produce glucose form non carbohydrates substances present in our body. This production of glucose increases the concentration of glucose in the blood and the body used this glucose for the generation of energy molecules in the form of ATP.
Why dos a single X chromosome that carriers the allele for red-green color blindness cause males to be color blind but doesn’t cause females to be color blind?
Answer:
Because females have two X chromosomes and the red-green color blindness allele has to be in both chromosomes to cause the woman to be color blinded. In the case of males, they only have one X chromosome, so if the allele for red-green color blindness is in the chromosome, the male will be color blinded since there is no other X chromosome with the normal allele as in females.
Explanation:
What determines if a person's sex is the genes X and Y. A sperm carries one of these two genes. When it meets the egg, this one will give the other chromosome, which is always X. So, if the sperm carries the X chromosome, the result, when the egg's fertilized, will be XX, which will give the information to develop a female human. If the sperm carries the Y chromosome, the result will be XY, which is a male.
As females are XX, if the red-green color blindness gene is in one of them, the other chromosome, which does not have this allele, will prevent the woman from being color blinded. We can say that women have a backup copy that prevents color blindness.
In the case of males, as they are XY, there is no extra copy that can prevent them from being red-green color blinded, so when a male has an X chromosome with this allele, they will be color blinded. In the case of women, they will only be carriers of the gene and will be color blinded if the two X chromosomes have the red-green color blindness allele.

In the experiment, "Do white cats eat more than black cats?" the independent variable would be:
the color of the cat.
how much each cat weighs.
how much food each cat eats.
the temperature of the food.
In the given experiment, the independent variable would be the color of the cat. Thus, the correct option for this question is A.
What is an Independent variable?An independent variable may be defined as a type of variable that significantly and effectively stands alone and isn't changed by the other variables you are trying to measure. The independent variable is the cause. Its value is independent of other variables in your study.
According to the context of this question, the color of the cat would not depend on how much food a particular type of cat eats. This will depend on the nature and diet of the cat along with its physiology and pattern. So, the color of the cat would be thought to be the independent variable in the experiment because it does not make any sense in the eating cat.
Therefore, in the given experiment, the independent variable would be the color of the cat. Thus, the correct option for this question is A.

A community ecologist would most likely study A. population growth of a single species. B. interactions among individuals of different species living in a small area. C. the cycling of matter through biotic and abiotic components of a geographical area. D. interactions among individuals of the same species living in a small area. E. energy flow through an ecosystem.
Answer:
The correct answer is B. interactions among individuals of different species living in a small area.
Explanation:
A community ecologist studies the set of populations of organisms of different species that inhabit and interact with each other in the same place for a period of time. The ecological community has to be studied as a unit or set and not independently each species of living beings that forms and interacts, that is, their distribution, organization, quantity, demography and reciprocity between the different populations that cohabit are included. Likewise, the main perspective of a community ecologist is found in the interrelationships between populations depending on the genotypic and phenotypic characteristics determined.
Della and Nick drove at constant
speed from town A to town B along
the same road. The distance between the
two towns was 210 km. Nick left
Town A half an hour later than Della
Both of them arrived in Town B at
the same time . Della drove at a
Speed of 60 km/h Find Nick's speed.
Plzz help mee
Answer:
70 km/hr
Explanation:
Distance between town A and B = 210 km
Della's speed = 60 km/hr
Time taken by Della = distance / speed
Time taken by Della = 210 km / 60km/ hr
Time taken by Della = 3.5 hours
Since Nick left half an hour later Than Della ;
Then, Nick's travel time = 3.5 - 0.5 = 3 hours
Nick's average speed = Distance /time
Nick's average speed = 210 / 3 = 70km/hr
Genetic engineering techniques can be used when analyzing and manipulating DNA and RNA. Scientists used gel electrophoresis to study transcription of gene L and discovered that mRNA strands of three different lengths are consistently produced. What explanations best accounts for this experimental result?
Answer:
the precursor messenger RNA (pre-mRNA) of the L gene underwent alternative splicing, thereby producing three different mRNAs that have different lengths
Explanation:
In eukaryotic organisms, transcription produces a precursor mRNA (pre-mRNA), which is a non-processed RNA sequence that contains both non-coding regions (i.e., introns) and coding regions (i.e., exons). Subsequently, this pre-mRNA is converted into a mature messenger RNA (mRNA) by a process known as 'alternative splicing', where introns are removed and exons and exons spliced together to form a contiguous coding sequence. During alternative splicing, differential combinations of exons can be produced from the same gene, producing different mRNAs with different lengths.
The experimental results with the gel electrophoresis of the transcription of mRNA are due to the alternative splicing.
What is alternative splicing?The genes are the codes that are enabled the formation of the DNA and RNA by expression. The transcription is the process of formation of mRNA from DNA template.
The mature mRNA is formed by the alternative splicing of the introns and the joining of exons for the functionalization. The process of alternative splicing results in the formation of the mRNA of multiple length.
The gel electrophoresis bands resulted have multiple length of mRNA. The results are the explanation for role of gene L in alternative splicing of mRNA.

Explain what is “bottleneck” and why genetic drift is more powerful in small populations.
Answer:
because more is being forced through
Explanation:
Answer:
A bottleneck in genetics is an event that kills off or isolates a large portion of the population.
Explanation:
The more individuals in a population, the greater the genetic diversity. A genetic bottleneck happens when the number of individuals in a population gets greatly reduced. This happens as a result of random chance. For example, a storm might come through and knock down a bunch of trees. Birds that live in the trees may get harmed and those that survive now have to find a new home, so they migrate to other areas leaving behind a small population. This is important because the fewer individuals there are, the less genetic diversity and therefore, the less ability of the population to adapt. If you have lots of different genes available and a new disease arises in the population, it's more likely that some individuals will survive. If you only have a few genes available, it is less likely any individuals will survive. This can lead to really quick adaptation and evolution of a species.

In the glycolytic pathway, the enzyme triose phosphate isomerase catalyzes the production of glyceraldehyde 3-phosphate (GAP) from dihydroxyacetone phosphate (DHAP). GAP continues through glycolysis via the reaction catalyzed by glyceraldehyde 3-phosphate dehydrogenase. In a muscle (myocyte) cell culture model, anaerobic conditions lead to cell death when triose phosphate isomerase is inhibited. In this same model, cells with inhibited triose phosphate isomerase survive under aerobic conditions. Briefly explain these findings including a discussion of energy production in anaerobic versus aerobic metabolism.
Answer:
In an anaerobic environment, organisms convert glucose into ethanol or lactate. In this condition, glycolysis generates 2 molecules of ATP and one molecule of NADH with the pyruvate. NADH molecule supports glycolysis by oxidized to NAD+ during the fermentation process.
Here one 6-C molecule breaks into two molecules G3P and DHAP, TPI or triose phosphate isomerase interconvert these two isomers and each triose is responsible for the production of two ATP molecules but if TPI is inhibited then there will be one ATP production which is not enough for supporting cellular process under the absence of oxygen and cell do not survive.
But in aerobic conditions pyruvate converted to acetyl CoA which produces 3 NADH, 1 FADH2, and 1 ATP that will get enough ATP by the oxidative phosphorylation hence will survive even if TPI is inhibited.
