If 800 offspring were produced from the cross, in what numbers would you expect the following phenotypes?
__wild type : __ miniature wings : __ garnet eyes : __ miniature wings, garnet eyes
Enter your answer as the number of flies of each phenotype separated by a colon (example: 100:300:100:300).
Answer:
Part A:
2. wild type (m+g+/mg)
4. miniature wings, garnet eyes (mg/mg)
Part B:
32:368:368:32
Explanation:
When calculating the recombination frequency, we need to know that 1% of recombinations = 1 map unit = 1cm. And that the maximum recombination frequency is always 50%.
The map unit is the distance between the pair of genes for which every 100 meiotic products, only one results in a recombinant one.
So, en the exposed example:
PART A:
First, we need to Identify the gametes for the individual with the genotype m + g / mg + and label parental and recombinants
Gametes:
m+ g parental type m g+ parental type m+ g+ recombinant typem g recombinant typeKnowing that the only possible gamete type for the other parental is mg, then we can identify the phenotypic classes of the offspring that were generated as a result of a crossover event. These would be
2. wild type (m+g+/mg)
4. miniature wings, garnet eyes (mg/mg)
PART B:
We know that the total number of individuals equals 800.We also know that the distance between genes equals 8 MU.To calculate the number of the phenotypes among the offsprings,
8 map units = 8% of recombination in total
= 8/2% m+g+/mg + 8/2% mg/mg
= 4% + 4%
The recombination frequency of m+g+/mg equals 0.04
The recombination frequency of mg/mg equals 0.04.
100% - 8% = 92% of parental in total =
= 92/2% of m+ g/mg + 92/2% m g+/mg
= 46% + 46%
The recombination frequency of m+g/mg equals 0.46
The recombination frequency of mg+/mg equals 0.46.
The frequency for each ggenotype is:
F (m+g+/mg) = 0.04 F (mg/mg) = 0.04. F (m+g/mg) = 0.46 F (mg+/mg) = 0.46.The number of individuals with each genotype is:
m+g+/mg = 0.04 x 800 = 32mg/mg = 0.04 x 800 = 32m+g/mg = 0.46 x 800 = 368m g+/mg = 0.46 x 800 = 36832 wild type : 368 miniature wings : 368 garnet eyes : 32 miniature wings, garnet eyes
A plant and an animal are both living things. According to the Cell Theory, what can you conclude about these two
very different organisms? SC.912.L.14.1
Plants have cells but animals do not
They are both made of one or more cells.
They both come from the same kind of cell.
O They both come from a non-living organism.
Answer:
They are both made of one or more cells.
Explanation:
A plant and an animal are both living things. According to the Cell Theory, what we can conclude about these two very different organisms is that they are both made of one or more cells.
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Generally, cells have the ability to independently replicate themselves.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles and they include nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, vesicles, etc.
Which of the following was NOT one of Darwin's
arguments for his theory of natural selection?
A) There is variation among individuals in a
population
B) Much variation is heritable
C) Populations possess an enormous reproductive
potential
D) Resources are abundant
E) Population sizes remain stable
Answer:
option D) resources are abundant.
Explanation:
according to Darwin resources are small. individuals of a population compete for these resources.
Charles Darwin not only proposed that species could change over time, but he also described a process by which these changes could occur. What was that process?
Answer:
Charles Darwin had a theory that states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. ... As a consequence those individuals most suited to their environment survive and, given enough time, the species will gradually evolve.
The theory of natural selection was proposed by Charles Darwin. Darwin postulated that species could change over time.
What is the theory of natural selection?The adaption by organism according to the surrounding environment is natural selection. It drives evolution.
Individuals in a population vary naturally. It means they are all different in some ways.
This variation means that some individuals have traits that suit better to the environment as compared than others.
This causes the species to change over time.
Thus, the process by which these changes take place is natural selection.

How would I explain the carbon cycle to a 1st grade classroom?
Answer:
To a 1st Grader:
Carbon is the magic element that is the basis of life on Earth. All living things contain carbon. Animals breathe it out, and plants breathe it in. Plants, people and animals depend on each other.
The carbon cycle is a process where carbon dioxide travels from the atmosphere into living organisms and the Earth, then back into the atmosphere. Plants take carbon dioxide from the air along with water and photosynthesis from the sun and use it to make food.
Explanation:
The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Carbon is the main component of biological compounds as well as a major component of many minerals such as limestone. To a first grader is different because they wouldn't understand what half of these words mean lol.
The carbon cycle is the biogeochemical cycle that exchanges carbon between the Earth's biosphere, parallel layers, geosphere, hydrosphere, and atmosphere.
What is the importance of carbon cycle?The carbon cycle is nature's method of recycling carbon atoms, which travel from the atmosphere into organisms on Earth and then back into the atmosphere.
The majority of carbon is stored in rocks and sediments, with the remainder in the ocean, atmosphere, and living organisms.
The carbon cycle is critical to the survival of life on Earth. Nature has a tendency to maintain carbon levels in balance.
This means that the amount of carbon naturally released from reservoirs equals the amount naturally absorbed by reservoirs. Maintaining this carbon balance ensures that the planet remains habitable for life.
Thus, by regulating the rate of carbon dioxide in the atmosphere, the carbon cycle plays an important role in regulating Earth's global temperature and climate.

The diagram above represents the phases of the moon. Position 1 represents the
new moon. Positions 2 through 8 represent the phases of the moon that follow.
Which phase does position 8 represent?
Answer:
waxing crescent
Explanation:
Position 8 represents waxing crescent phase. It is observed after a new moon and can be observed until the first quarter of moon.
What are the phases of moon?The waxing and waning nature of the moon is responsible for its various phases. This is due to the fact that moon is the only natural satellite of the earth. It revolves around the earth in a fixed orbit.
As earth revolves around the sun, the sunlight that falls on moon makes us visble those parts. Thus, it appears that moon is changing its shape.
A lunar month which is of 29.5 days usually is contains four primary and four intermediate phases. It is described as: New moon, Waxing crescent moon, First quarter, Waxing gibbous moon, Full moon, Waning gibbous, Last quarter and Waning crescent moon.
These phases have specific time in which they can be observed in the sky. New moon is an exception, as no part of the moon is visible then.
The phases of the moon are therefore considered as astronomically important.
