The pedigree below depicts a dominant trait. What is the genotype of individual I-1 (use the letter A for a dominant allele and a for a recessive allele)? How did you come to this conclusion? Using your best grammar, write 3-5 sentences.
A pedigree chart is a diagrammatic representation showing the occurrence and appearance of phenotypes of a particular gene/traits and its ancestors from one generation to the next establishing relationships between individuals in a family.
Using the letter A for a dominant allele and a for a recessive allele, the genotype of individual I-1 is Aa.
In the key pedigree nomenclature, an individual marked with the black ink is affected with the trait (and this trait is dominant - A). Looking at the F1 generation, there are males affected and females as well. For inheritance of the trait, just one copy is enough to become affected. Therefore, the male parent is heterozygous for the trait and the female normal (aa) to enable the production of both affected and non-affected individuals.Learn more about pedigrees: https://brainly.com/question/318443

1. Describe the flow of energy from the sun to a producer, like grass, and then to a consumer, like a rabbit. 100 points!!! Not a scam!
Answer: The sun produces energy to the solar panel the sollaer panel produces energy to my house
Explanation:
The Sun then provides energy to the grass via the photosynthesis process. The rabbit consumes the grass and absorbs its energy.
What is flow of energy?The flow of energy through living things within an ecosystem is referred to as energy flow.
All living organisms can be classified as producers and consumers, and those producers and consumers can be classified further as a food chain. Each level of the food chain is referred to as a trophic level.
The Sun then provides energy to the grass through photosynthesis. The rabbit consumes and absorbs the grass's energy.
Finally, the snake consumes the rabbit and absorbs its energy. Energy travels from the Sun and is consumed by each consumer along the chain.
Thus, this way, energy flows in an ecosystem.

Answer: 60 degrees the front is cold so it would be 60 degrees in Virginia the next day
ExplanationExplanation:
Based on the consistant pressure that the front seems to be causing, temperatures will become cooler. Based on the four choices provided, only one makes the temperature cooler which is A.
This front seems to be making its appearance during the overnight hours, therefore causing colder temperatures the morning following. With temperatures being 68 degrees at the time, the external temperature will be cooler than 68 degrees.
science questions , may be out of order but please help asap ( about mitosis ) may be out of order so i made two questions
Answer:
8. Prophase
9. Gap 1
10.Metaphase
Explanation:
Basically from what I remember
Prophase: Mitosis begins, nuclear envelope is gone
Metaphase: Chromosomes line up and spindle fibers attatch
Anaphase: Chromosomes are torn apart to separate sides of the cell
Telophase: Separates duplicated genetic material into 2 identical nuclei
Cytokenesis: The cytoplasm itself separates and forms 2 cells.
Gap 1: Cells increase in size as new organelles are formed
Synthesis: DNA is formed
Gap 2: DNA is checked as cell begins to divide
Mitosis: Cell divides
So from the simplified versions of things I remember, I think the answers listed above probably suit each question best.
Hope I helped a bit!

Available data:Single diallelic gene codes for hair in Guinea pigsAllele H is dominant and codes for having hairAllele h is recessive and codes for not having hair
For this gene we will assume complete dominance, meaning that the dominant alele completely hides the expression of the recessive allele.
According to this information, we can say that
Genotype Phenotype
HH Hairy pig
Hh Hairy pig
hh Hairless pig
9) Geneviene does not have hair ⇒ Its genotype is hh
10) Fred has hair ⇒ Its genotype is HH or Hh
Possible crosses
11 and 12)
Cross1: If Fred was genotype HH and bred with Genevieve
Parentals) HH x hh
Gametes) H H h h
Punnett square) H H
h Hh Hh
h Hh Hh
F1) 100% of the progeny is expected to have hair and be heter0zyg0us, Hh.
13 and 14)
Cross2: If Fred was genotype Hh and bred with Genevieve
Parentals) Hh x hh
Gametes) H hh h h
Punnett square) H h
h Hh hh
h Hh hh
F1) 50% of the progeny is expected to have hair and be heter0zyg0us, Hh.
50% of the progeny is expected to be hairless and be h0m0zyg0us recessive, hh.
15)
• If the individual with the unknown genotype (Fred) is heter0zyg0us, the phenotypic rate of the descendants is 50% heter0zyg0us -Hh- and 50% h0m0zyg0us recessive -hh-.
• But if the individual with the unknown genotype is h0m0zyg0us dominant, the phenotypic rate of the descendants is 100% heter0zyg0us for the trait, Hh.
16)
The weakness is that even if Fred is heter0zyg0us for the trait, when making the cross it might occur that all individuals in the progeny are born h0m0zyg0us recessive, and there is a risk of missinterpreting the results.
So in that situation, many crosses must be done between fred and genevieve to se sure about Freds genotype.

Individuals, as well as industry—and automobile manufacturers in particular have an obligation to work to reduce carbon dioxide emissions that may increase the level of greenhouse gases in the atmosphere. Agree or disagree
It is right that individuals, as well as industry—and automobile manufacturers, in particular, have an obligation to work to reduce carbon dioxide emissions that may increase the level of greenhouse gases in the atmosphere.
Carbon dioxide is a greenhouse gas, which means that it traps heat in the atmosphere. This can lead to climate change, which is already having a number of negative effects on the planet, such as rising sea levels, more extreme weather events, and changes in plant and animal life.
Individuals can reduce their carbon dioxide emissions by making changes to their lifestyle, such as driving less, using less energy at home, and eating less meat. Industry can reduce their carbon dioxide emissions by investing in new technologies, such as renewable energy and energy efficiency.
Automobile manufacturers have a special responsibility to reduce carbon dioxide emissions, as cars are a major source of greenhouse gases. They can do this by designing more fuel-efficient cars and by using alternative fuels, such as electric and hybrid cars.
It is important for everyone to do their part to reduce carbon dioxide emissions. By working together, we can help to protect the planet for future generations.
