What is the probability of getting dwarf plants with red
flowers in the F1 progeny?
Answers
Answer:
2/8
Explanation:
I did this before
1/8 or 12.5% is the probability of getting dwarf plants with red flowers in the F1 progeny.
What is a dihybrid cross?Dihybrid is defined as the cross observed between two characters, in which two different gene is responsible for the two particular characters.
In the given question plant height and flower color are observed. A tall pea plant with red flowers (TtRr) is crossed with another tall pea plant with white flowers (Ttrr).
Gametes: TtRr - TR, Tr, tR, and tr
Ttrr - Tr, Tr, tr, and Tr
Genotypes: Tall, Red (T_R_) = 6
Tall, white (T_rr) = 6
Dwarf, red (ttR_) = 2
Dwarf, white (ttrr) = 2
Therefore, the probability of getting dwarf plants with red flowers in the F1 progeny is 1/8 or 12.5%.

What % of energy does plants receive from the sun
Answers
Answer:
Most solar energy occurs at wavelengths unsuitable for photosynthesis. Between 98 and 99 percent of solar energy reaching Earth is reflected from leaves and other surfaces and absorbed by other molecules, which convert it to heat. Thus, only 1 to 2 percent is available to be captured by plants.

10. Which arrow or arrows represent reactions that demonstrate a conservation of mass and energy? Explain your answer.
________
Answers
7. Is true because Solar energy is created when it is used in the process of photosynthesis in a plant. Then chemical energy is used when the plants create glucose.
8. Arrows C + F represent a release of carbon dioxide. Arrow C shows carbon being released into the air from the factory. Arrow F shows respiration and carbon being released.
9. The cycle would be made by process C and E. The process E happen when the organism dies and become a fossil. The organism could be a cow that eats grass(plants) that takes carbon from the atmosphere by doing photosynthesis.
The process in C happens when the factory (nonliving) using fossil fuel and produce carbon. The factory takes the fossil, use it as fuel, and return the carbon to the atmosphere.
10. The process of photosynthesis and cellular respiration can represent the law of conservation of mass and energy. In photosynthesis, you need sunlight(arrow A), carbon dioxide(arrow B) and water. The process will produce glucose which can be used in cellular respiration.
In cellular respiration, the glucose will produce energy which was made from sunlight. It will also produce water and carbon dioxide that will be released back into the atmosphere (arrow F)

Answers
Answer:
A. Four siblings' cells are similar to their parents' cells.
Explanation:
Genetics of offspring are based on the paten but it will never be identical to them. The reason why is when the male and female cells combine to form a child they mix and most of the time one will dominate the other. You can have cases where you have both alleles though. Sometimes they also mix to form a new one. But usually you'll get one from each parent.

Answers
Scale can be extremely important to consider when applying the conclusions of an investigation to a larger group.
Scale is defined as a series of measurements in a given ratio, in order to compare two objects or groups. Some examples include:
Scale modelsScale populationsIn the case of scale models, one example may be creating a 1:100 scale model of a building. What this means is that the model created will be one hundred times smaller than the original.
The idea of scale is very important to consider when performing experiments. For example, if we were to take a sample of 10 people and test for a specific bacteria, which gives us a result of 1 in 10 (or 10%) of the people that test positive for the bacteria, it would seem as though it is a very small number of people. However, if we take scale into consideration we can apply this 10% to the global population, which will result in hundreds of millions of people who will test positive for the bacteria.
Scale is important to consider when performing any experiment or drawing conclusions because it offers a method to calculate and make an educated assumption as to the impact of the results on a population that would otherwise be impossible to test.

Answer:
A. Nucleotide bases in one strand can only be paired with specific bases in the other strand.
Explanation:
Had the same question on a test. Hope this helps :)
DNA is a genetic material found in every living organism. DNA is made up of purines, pyrimidines, a pentose sugar, and phosphate backbone. DNA is a genetic material that carries information from parent to daughter cells.
The correct answer is:
Option A. Nucleotide bases in one strand can only be paired with specific bases in the other strand.
Characteristics of the DNA include:
1. DNA is a double-stranded genetic material, which is made up of four nitrogenous bases, adenine, cytosine, thymine, and guanine.
2. These nucleotides bind to specific nucleotide sequences present on the template strand of the DNA.
3. DNA consists of coded sequences known as genes, which are inherited from the parent to the daughter cells.
4. DNA undergoes a unique semi-conservative mode of replication.
Thus, the correct answer is the ability of the DNA nucleotides to bind to the specific bases in the other strand.
