Answer:
1 AU means 1 astronomical unit or the aproximate distance from the earth to the sun
1AU=149597870.7 kiometers
1 billion=1,000,000,000
600 billion=600,000,000,000
x times 1AU=600,000,000,000
x times 149597870.7=600,000,000,000
solve for x
divide both sides by 149597870.7
x=4010.75
so aprox 4011 AU's
Answer:
A, B AND E
Sepals, petals, stamens and carpel
Explanation:
These floral structures which are attached to the receptacle in whorls include the following:
- Sepals which protect the inner parts of the flower especially in the early stages of development.
- petals are brightly coloured, large and conspicuous especially in insect-pollinated flowers. If petals are fused, the corolla is said to be gamopetalous.
- Stamens constitute the androecium, which is the male part of the flower. Stamens are made up of filaments and anthers which produce pollen grains.
- Carpel form the pistil or gynoecium which is the female part of the flower. A carpel is made up of stigma, style and ovary.
Answer/Explanation:
Red/green colorblindness is a recessive, X-linked condition. That means that the affected gene is on the X chromosome, and that the phenotype will only be present if there is no "healthy" gene, which is dominant to the mutated gene.
For two unaffected people to have an affected son, the mother must be a carrier. Remember, females have two X chromosomes and males have one. So if a female is a carrier of the colorblindness mutation, she will have one copy of the mutation and one normal copy of the gene, and will therefore be unaffected.
The punnet square (attached) shows that all their female children would be unaffected (have the B gene), but 1:2 male children would be colorblind, as their only copy of the gene is mutated (b).
Answer: Explanation:
Water is formed when hydrogen and oxygen react to form H2O during the electron transport chain, which is the final stage of cellular respiration.
Im pretty sure the answer is elk, since they were eaten by the wolves in the rocky mountains.
