A biology class wanted to study the effect of different materials on the melting rate of ice. They placed pieces of ice, each wi

th a mass of 10g, onto trays. Group 1 was covered in plastic, group 2 was covered in paper, group 3 was covered in aluminum, and group 4 remained uncovered.
Each piece of ice was allowed to melt for 15 minutes. Then final mass of the ice, minus the melted water, was recorded at the end of the experiment.

What components of a tossed salad will pass through the human digestive tract and be digested the least?
DochEvi [55]

Answer:

Cellulose (in the lettuce)

Explanation:

  • A tossed salad usually consists of many vegetables such as lettuce, onions, tomatoes, cucumbers, etc. and then, these vegetables have added dressings which can be of different types.
  • When a person eats a tossed salad then the lettuce will be least digested as it is composed mainly of cellulose and the human body is incapable of digesting cellulose.
  • The inability to digest cellulose by human beings is because there are beta acetal linkages present in the cellulose and human beings lack the enzymes that can break the linkage.
  • However, the undigested cellulose aids in the process of digestion as it acts like fiber and thus, the process of digestion can take place smoothly.
  • Thus, the intake of cellulose-rich foods is also essential.

Your grandmother is very impressed with the size of the tomatoes from a plant that she planted in her garden. These tomatoes are
marusya05 [52]

Answer: The blank can be filled correctly by "if the seeds contain the gene or allele responsible for large size of the tomatoes"

Explanation:

In plants also, characters or traits of characters are defined by genes. Different alleles produce different traits of the same character.

For example, in classic Mendelian genetics, T was the allele responsible for tall plant trait while t was the responsible for dwarf trait.

Similarly, there would be a gene(s) responsible for size of the tomatoes. In addition, seeds are the products of sexual reproduction of plants. So, they may carry genetic combination different from parent plants (due to meiosis, crossing over, independent assortment, et cetera).

So, if the seed contains the gene or allele responsible for large size of tomatoes then only they will produce same kind of tomatoes.
