True of false Mendel realized that when he crossed two pea plants that were the offspring of a pea plant with yellow peas and a
Sonbull [250]

Answer:

False

Explanation:

Mendel realized that the F2 had a phenotypic ratio 3:1, meaning 3/4 = 75% were yellow and 1/4 = 25% green.

Mendel observed that the F1 expressed only one of the alternative variants (in this case, only yellow seeds appeared), while the other variant (green) disappeared. Mendel named dominant the expressed variant. Mendel allowed auto pollination and observed that in the second generation, F2, the other disappeared variant reappeared. Both alternative variants were present in the F2. Mendel named recessive the second alternative variant.

Mendel thought that hereditary traits determined by discrete factors were the possible explication for these phenotypes. These factors should have been present in the F1 in pairs. One of them came from one parental plant, and the other factor came from the other plant. These factors then separated again when sex cells were produced, giving two types of gametes, each with only one factor.

Mendel concluded that each individual (plant) has a pair of factors (alleles), one for each trait (yellow and green) and that the pair separates (segregates) during the formation of the gametes. This conclusion is known as the segregation principle (First Mendels´ Low).

Primary reinforcers are related to secondary reinforcers in which of the following ways?
LuckyWell [14K]
You didn't provide us with any possible ways? Primary reinforcers are, however, types of reinforcers where they immediately elicit a reward or reward-like behavior once they are applied in a situation. An example would be apple juice. 

Secondary reinforcers on the other hand need to be associated with something for them to become reinforcers or they provide rewards in a non-direct way. An example would be money.

This is the main relationship between them.

How can you see change over time using topographic maps and satellite images?
Alexus [3.1K]

Topographic maps and satellite images

Explanation:

A topographic map represents earth's surface features like land forms and structures, rivers and lakes, mountains and hills, elevations and other natural features along with man-made artificial features like cities, buildings, monuments, roads, bridges etc. These are formed by contour lines.

Topographic maps are printed with revision dates to observe the changes happening on the Earth's surface. Various land forms keeps changing due to natural and man-made causes and these needs to be updated accordingly to provide accurate details.

A satellite image provides details of the earth aerially from space. These provides details of a land form or any earth structure currently.

By comparing with older satellite images or topographic maps with the current one, the changes which occurred over time can be observed.
