Individuals with the recessive trait of night blindness (genotype nn) have difficulty seeing in low light. The pedigree shows the inheritance of night blindness in a certain family.Which of these are possible genotypes of the parental generation? Refer to the figure below and match the angle with the correct measurement in degrees.
Answer:
Cool
Explanation:
The possible genotypes of the parental generation are as follows :
Male : Night Blindness Female : Normal What is Genotype ?Genotype is the collection of the the two alleles that makes up the gene inherited by an offspring from its parents.
Given that only one of the males of the first generation suffers from Night blindness, He inherited the Night blindness from the parental generation. therefore the male from the parental generation is a carrier of the Night blindness allele while the Female is not a carrier.
Hence we can conclude that The possible genotypes of the parental generation are Male : Night Blindness and Female : Normal.

If Pluto had not been demoted to a dwarf planet, what category of planet would it fall under? Explain your answer.
Answer:
The planet pluto originally was considered as a real planet until its demotion as a dwarf planet.
The reason it was demoted was because it was soon realized to not meet the three criteria of the International Astronomical Union used to define a full size planet.
So if pluto was not categorized as a dwarf planet than it would of just fallen under as a planet.
Explanation:
Not mine answer but it from purple6kabi
Answer:
The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet.

Explanation:
On the average, how much energy is lost from each trophic level? explain why
Answer:
I think it's 10% because some of it turns into heat energy
Explanation:
On average, about 90% of the energy is lost from each tropic level. The remaining 10% is available for the next trophic level.
The tropic level of the organisms is the position of organisms occupied in the food web. When an organism consumes other organisms as its food, the energy stored in the form of chemical energy in the organic molecules is converted into the energy used for cellular respiration.
This conversion is not efficient and the energy is lost in the form of heat. Some of the energy is used for growth and maintenance. While other energy is excreted.
Thus, when an organism consumed organic matter, 90% of the energy is lost and 10% of the energy is involved in the building of body tissues. This 10% of energy is passed to the next level.

A. under-populated land
B. overgrazing of farm animals
C. sufficient irrigation
D. failure to cultivate the land
Respuesta:
B. pastoreo excesivo de animales de granja
Porque son lugares secos.
Explicación:
Las políticas e infraestructuras que promueven la agricultura en las tierras de pastoreo que no pueden mantener sistemas viables de cultivo, contribuyen a la desertificación. La mayoría de las áreas de tierras secas (el 65%) son tierras de pastoreo que son más adecuadas para el pastoreo sostenible que para el cultivo.

Firmly hold with one hand the end of a ruler (or similar object) over the edge of a table. Pull the other end down gently and listen to the sound. Then give the ruler (or similar object) a harder downward pull, and see if there is a difference in sound. Describe what you hear and explain the difference using the terms “energy,” “amplitude,” “intensity,” and “decibel.”
2. Take some time to listen to sounds in your environment. Make a list of ten sounds, ranking them from the highest pitch to the lowest. Write a couple of sentences describing whether this was easy or difficult and why. (Some of the sounds can come from tapping objects that vibrate or playing musical notes on an instrument.)

How can the energy stored in the photosynthetic organism be used?
☁️ Answer ☁️
1: "Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules."
2: "The energy stored in the bonds to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as movement. "

Reflection Questions
1. Explain how biological evolution is supported by the fossil record.
2. Why is natural selection a mechanism for biological change?
3. How does chemical evolution explain the origin of life on Earth?
4. Explain why scientific theories, such as biological and chemical evolution, represent the
strongest explanation of the changes observed in the fossil record.
5. How can scientific theories on evolution and the fossil record change over time?
Answer:
1) The word ‘evolution’ was first mentioned in the book ‘The Origin of Species’ in 1859, by Charles Darwin. Darwin put forward the concept of evolution during his journey to the Galapagos Islands.
2)Natural selection is an important mechanism of evolution. It states that the organisms that are able to survive and reproduce with the changing environmental conditions are selected by nature while the ones that cannot survive are eliminated.
3) Evolution mainly deals with the origin of life on earth. The conditions and the forms of life on earth were entirely different from what we see today.
please forgive me I cant answer 4th one..
5)Charles Darwin, an English naturalist of the 19th century made an extensive study of nature for over 20 years.
1. The fossil record provides crucial evidence for biological evolution. Fossils are the preserved remains or traces of past organisms, providing a record of life on Earth over millions of years.
By studying fossils, scientists can observe changes in organisms and their characteristics over time. Fossils show a progression of simpler life forms in older layers to more complex ones in more recent layers.
2. Natural selection is a mechanism for biological change because it leads to the adaptation of populations to their environments over time. It is based on the concept that individuals within a population exhibit variation in traits, and those traits that enhance survival and reproduction are more likely to be passed on to future generations.
Through natural selection, individuals with advantageous traits have higher chances of surviving and reproducing, leading to the increased frequency of those traits in subsequent generations.
3. Chemical evolution, also known as abiogenesis or prebiotic evolution, explains the origin of life on Earth by proposing that life arose from non-living matter through a series of chemical reactions.
According to this theory, in Earth's early conditions, simple organic molecules formed from inorganic compounds through processes like lightning, volcanic activity, and reactions in the atmosphere and oceans.
These molecules then underwent further reactions, leading to the formation of more complex molecules like amino acids and nucleotides, which are the building blocks of proteins and nucleic acids, respectively.
4. Scientific theories such as biological and chemical evolution represent the strongest explanations for the changes observed in the fossil record because they are supported by extensive evidence from multiple scientific disciplines.
These theories have withstood rigorous testing, scrutiny, and peer review over many years. They are based on a large body of evidence, including the fossil record, comparative anatomy, genetics, molecular biology, and observations of natural populations.
5. Scientific theories on evolution and the fossil record can change over time as new evidence is discovered, technologies advance, and scientific understanding improves.
The process of scientific inquiry involves continuous investigation, testing, and refinement of theories based on new data and observations.
As scientists gather more evidence from fossil discoveries, genetic studies, experimental research, and other fields, our understanding of evolution and the fossil record can deepen and evolve.

Genetic recombination would be most closely associated with which process in disease-causing microorganisms?
A.binary fission in fungi
B.sexual reproduction in fungi
C.spore formation in bacteria
D.viral replication in host cells
Genetic recombination is most closely associated with: Choice D: Viral replication in host cells
Definition:
Genetic recombination (otherwise termed genetic reshuffling) is simply the exchange of genetic material between different organisms which leads to production of offspring with combinations of traits that differ from those found in either parent.
In retroviruses, recombination actually occurs at the point during replication when the retrovirus genome is in a DNA form and takes place by the same break-rejoin technique as in cells and DNA viruses.
Recombination can occur both between two related retroviruses and between the retrovirus DNA and the host DNA.
