Answer:

Polydactyly in the Amish population is an example of Founder effect

Polydactyly is an example of these founder effect that causes formation of extra finger which takes place when a a polydactyly man marry within their own community.

Explain why this difference between the inner and outer core's density exists?
Nataly [62]

Metals and the frequency in which they're found influences a lot since different metals have different densities. Heat also influences a lot since hotter things tend to be less dense though the inner core is more dense.

Answer:

The inner core is more dense because it's liquid and hotter, and since it's liquid the earth's movement makes it difficult for the inner core to be less denser than it is.

\bf~Inner~core:~12.8~g/cm^{2}

\bf~Outer~core:~9.9~g/cm^{2}

6 effects of weeds on crops​
garri49 [273]

Answer:

<em>1. They effect crop productivity</em>

As weeds start to grow in the area where the crops were destined to grow, the production of the crops gets lowered.

<em>2. They deplete the crops from nutrition</em>

The weeds will compete with the crop plants for resources such as minerals from the soil.

<em>3. They will deplete water resources</em>

The weeds will compete with the crop plants for water.

<em>4. Sun-light will be depleted</em>

The weeds will complete with the crop plants for sun light.

<em>5. The crop quality will be affected</em>

As the crop plants will be in competition with the weeds, hence their quality will be affected.

6.  <em>They can reduce the biodiversity of crop plants.</em>
