Answer:
The color of a tomato begins to change as it ripens, from green to yellow, and ultimately to red. This is due to the breakdown of chlorophyll, which results in the formation of lycopene, a red carotenoid (a pigment group). When the tomato is fully ripe, the carotenoid becomes the predominate color, which is red.
What is the half life of a radioactive isotope if a 500 gram sample decays to 62.5 grams in 99 years?
Answer:
24.75 years
Explanation:
62.5 is 1/4 of 500, which means that in 99 years it passed through four half-lifes. So, you divide 99 by four and you get that the half-life is 24.75 years. 25 years if it was rounded
Which statement describes nuclear fission?
o the joining of two nuclei
o the use of neutrons to make energy
O the splitting of a nucleus
o the production of electricity from atoms
According to the the concept of nuclear reactions ,nuclear fission is the splitting of the nucleus.
What are nuclear reactions?
There are two types of nuclear reactions which are nuclear fusion and nuclear fission .They involve the combination and disintegration of the element's nucleus respectively.
In nuclear fission, the nucleus of the atom is bombarded with electrons of low energy which splits the nucleus in to two parts .Large amount of energy is released in the process.It is used in nuclear power reactors as it produces large amount of energy.
In nuclear fusion,on the other hand, is a reaction which occurs when two or more atoms combine to form a heavy nucleus.Large amount of energy is released in the process which is greater than that of the energy which is released in nuclear fission process.

Transfusing mismatched blood types is a problem for a patient because A. it slows down digestion. B. it changes blood composition. C. it causes infection. D. it causes clots in blood vessels.
Answer:
D. it causes clots in blood vessels.
Explanation:
If you receive blood that is not compatible with your blood, your body produces antibodies to destroy the donor's blood cells. This process causes the transfusion reaction. Blood that you receive in a transfusion must be compatible with your own blood.

which classification groups have linear chromosomeswhich classification groups have linear chromosomes
Until recently, prokaryotes did not contain linear plasmids or chromosomes, but they have since been discovered in spirochaetes, Gram-positive bacteria, and Gram-negative bacteria. Bacterial linear DNA has been classified into two structural kinds. Each end of linear plasmids from the spirochaete Borrelia has a covalently closed hairpin loop, while each end of linear plasmids from the Gram-positive filamentous Streptomyces has a covalently connected protein. In eukaryotic cells, replicons with comparable structures are more common than in prokaryotes. However, linear genomic architectures are likely more widespread in bacteria than previously thought, and some replicons may be able to switch between circular and linear isomers. The molecular biology of these widely scattered pieces reveals information about the origins of linear DNA in bacteria, including evidence of prokaryote-eukaryotes genetic exchange.
During a Vo2max test, many people have a Respiratory Exchange Ratio greater than 1.0 as they approach their VO2max. Why
The important of RER between 0.7 and 1 shows a blend of carbohydrates and fat as a basis of energy. In case the value is more significant than 1, it means anaerobic respiration as a result of more carbon dioxide being developed than the oxygen that is being consumed.
What is the difference between vo2max and relative vo2max?Absolute VO2 max is only the amount of oxygen you breathe in liters per minute.
This dose depends on your age, weight, size, and gender. Relative VO2 maximum Relative VO2 max calculates your weight in liters per minute per kilogram of body weight.
Thus, anaerobic respiration results of more carbon dioxide being forged than the oxygen that is being destroyed.

What determines the type of feedback? A. How close to equilibrium the characteristic is B. How the body responds to a change C. How much product is present already
Answer:
The awnser is B
Explanation: no explanation
The fact that determines the type of feedback is "How the body responds to a change?" Thus, option B is correct.
What is positive feedback?A feedback has been known as the process where a system responds to an external or internal stimulus. There are two major types of feedback in a system, they are negative and positive feedback or we can say that there are two types of feedback is there one is positive feedback and another one is negative feedback.
Positive feedback is a type of response that occur when an output or response is an enhancement of the input. It's output moves further away from equilibrium. A negative feedback occur when a fraction of the output is fed back to the system to control fluctuation of other output.A feedback has been known as the process where a system responds to an external or internal stimulus.
Therefore, The fact that determines the type of feedback is "How the body responds to a change?" Thus, option B is correct.

What is the correct sentence?
Genes code for proteins, and proteins code for traits.
Proteins code for genes, which code for traits.
Traits code for genes, and genes code for proteins.
Answer: The correct sequence in the expression of a trait is gene > protein > trait (Option B).
Explanation:
During gene transcription, a linear fragment of DNA referred to as a 'gene' is used as template to synthesize a complementary messenger RNA (mRNA) sequence.
Subsequently, this mRNA is then used as template to create a protein by a process called translation.
Moreover, phenotypic traits can be defined as all observable characteristics that an organism has.
The phenotypic traits are largely determined by the expression of either enzymatic or structural proteins, which interact to shape the phenotype of an organism.
In conclusion, the correct sequence in the expression of a trait is gene > protein > trait (Option B).
Answer:
Genes code for proteins, and proteins code for traits.
Explanation:
Simplified Response:
Genes direct the synthesis of RNA through transcription and translation. Through these processes, proteins are assembled. These proteins form the structures and functions that make up all living organisms. And therefore, these proteins are responsible for the traits of living organisms as well.
So, that's why the correct choice would be the first option.
Genes --> Proteins --> Traits
6. How did natural selection work in the red-eye frog egg hatching?
7. What was the explanation regarding the phenotypic plasticity of the red-eye frog eggs?
We can confirm that natural selection resulted in the coloration of the red-eye frog due to its higher chance of survival with this change in pigment.
Why would this color help the frog survive?Bright pigments are a common defense mechanism in nature. Organisms that are poisonous often evolve bright coloration as a warning to predators. Over time, natural selection ensures that the organisms who've successfully incorporated this pigmentation have much higher survival rates and therefore the species entirely evolves into possessing this trait, as was the case with the red-eye frog.
Therefore, we can confirm that natural selection resulted in the bright pigmentation of the red-eye frog because of the much higher survival rate that this adaptation afforded the organism.
