The Milkmaid and Her Pail
A farmer's daughter had been out to milk the cows, and was returning to the dairy carrying her pail of milk upon her head. As she walked along, she fell a-musing after this fashion: "The milk in this pail will provide me with cream, which I will make into butter and take to market to sell. With the money I will buy a number of eggs, and these, when hatched, will produce chickens, and by and by I shall have quite a large poultry-yard. Then I shall sell some of my fowls, and with the money which they will bring in I will buy myself a new gown, which I shall wear when I go to the fair; and all the young fellows will admire it, and come and make love to me, but I shall toss my head and have nothing to say to them." Forgetting all about the pail, and suiting the action to the word, she tossed her head. Down went the pail, all the milk was spilled, and all her fine castles in the air vanished in a moment!
- Do not count your chickens before they are hatched.
I tried to make my own but it turned out bad...
Hope this helps ❤️
Answer:
1. aa
2. They have similar DNA
Explanation:
1. According to the question 1, wrinkled seeds (A) are dominant over round seeds (a) in pea plants. This means that, based on the law of dominance proposed by Mendel, wrinkled seeds will be expressed over round seeds in a heterozygous state (Aa).
However, since the round seed phenotype is a recessive trait, it will only be expressed when the alleles for round seeds (a) are the same in the gene i.e. aa genotype.
2. Based on the information in question 2, Ricky, who is working on a family tree for his school project, realizes that his close relatives all look similar in the pictures he collected. This is possible because of the SIMILARITY OF THEIR DNA (genetic material). Note that, relatives are connected by the genes that are inherited from one another, hence, they possess a similar DNA, which is the most valid reason for the resemblance.
Answer:
D. The rock cycle is a series of processes in which one kind of rock is transformed into other kinds.
Explanation:
One way of expressing concentration is by molarity. It is the amount of solute per unit volume of the solution. Usually, it takes the unit mol/L. The calculation for this problem is as follows:
1.02 mM = (1.02 mol / mL) (2.0 mL) = 2.04 mol
Thus, the solution has 2.04 mol of glucose.
