Two cities are separated by 200 miles. City X has an altitude of 122 meters and City Y has an altitude of 260 meters. Calculate
OleMash [197]

Answer: 0.69 m/ mile.

Explanation:

The altitude gradient between two cities X and Y = \dfrac{\text{Altitude of City Y - Altitude of city X}}{\text{Distance between two cities}}\times100\%

Given: Two cities are separated by 200 miles.

City X has an altitude of 122 meters.

City Y has an altitude of 260 meters.

The altitude gradient between two cities X and Y =

\dfrac{260-122}{200}=0.69\text{m/ mile}

Hence, the altitude gradient between the two cites = 0.69 m/ mile.

Part E Your molecular clock model resembles another branching chart, the phylogenetic chart, which you’ve used in this unit. Rev
Nikitich [7]

Answer:

The phylogenetic graph uses several types of variables to be formed, while other models use only one type of variable.

Explanation:

To create a phylogenetic chart, matrices with data on the studied species are used. These data are composed of morphological, chemical and / or genetic information that allow a detailed investigation about the ancestry of each species, in addition to allowing the correct grouping based on this ancestry and evolution.

A phylogenetic graph is different from other molecular models due to the number of data considered by it, since other models, such as the molecular clock, for example, only consider genetic based information.

What two characteristics do fungi lack that forced them to become decomposers
Artist 52 [7]
Fungi are decomposers, they obtain their food from dead organic matters. Fungi obtain their nutrient this way because they can not produce their own food. To produce their own food they need chloroplast in their cells to obtain energy from the sun. And they also need the ability to fix nitrogen which they will incorporate into the food they produce. Because they lack the ability to do this thing, they have to adapt to eating dead materials. <span />
