Don't understand how this was particularly hard; I feel people are just lazy.

The answer is ecosystem.
This is because c refers to a single animal or species. (i.e. population of wolves in said ecosystem.)
Community would be specifically the animals living in an area.
And a landform is the natural feature of a solid surface.

Which value is being measured in the columns labeled fraction remaining and percentage remaining

ahrayia [7]

Question:

Which value is being measured in the columns labeled "Fraction remaining” and "Percentage remaining”?

years of decay
quantity of energy
number of stable atoms
amount of material that has not decayed

Answer:

"Amount of material that has not decayed" being measured in the columns labelled "Fraction remaining” and "Percentage remaining”

Explanation:

The table shown below having explains about the half life , the amount of sample in both fraction and percentage. The first column named half life elapsed tells us the the number of half life that that is completed. Half life is the time taken for an element to reduce or decay into half of its initial amount.

The fraction remaining column gives the amount of sample that is left behind after the half life particular number of half life has completed. similarly the percentage remaining column gives the amount of sample in percentage. For example, the 5th row tells us that after 4 half life is over $\frac{1}{16} th$ of the sample remained. In percentage it is 6.25%

Explain Mendel's law of independent assortment and how the 9:3:3:1 phenotypic ratio among the F2 of a dihybrid cross provides ev

GrogVix [38]

Answer:

Explanation:

Mendel's law of independent assortment state that two different genes assort independently in gamete formation.

To reach this conclusion, one has to do a dihybrid cross. This means that two genes responsible for different traits need to be analyzed at the same time.

1) Starting with a parental generation of a cross between two pure lines (homozygous for both genes) with different traits, a plant with yellow and round seeds (YYRR) and another with green and wrinkled seeds (yyrr). The F1 will be phenotypically homogeneous (yellow and round), and genotypically heterozygous (YyRr).

2) If the individuals from the F1 are crossed with one another, we have to do a Punnett Square to determine the phenotypic ratio of the F2.

If the genes assort independently, the F1 individuals will produce their different gametes with the same probability. Each possible gamete will appear in a 1/4 proportion: YR, Yr, yR, yr.
The 9:3:3:1 ratio is a result of analyzing the possible phenotypes that result from the dihybrid cross.

See the attached image for an illustration of the crosses in each generation and the Punnett Square.
