Mining can influence the local communities both positively and negatively. The positive influences like generating employment and community development projects are essential for the native people, however, only two positives do not cover up the potential negatives of mining.

Some of the negative impacts of mining on the local communities are:

1. Obstructing them from using clean water and land.

2. Forcing them from their homes and land.

3. Modifying the social dynamics of a community.

4. Exhibiting influences on their health and livelihoods.

5. Exposing them to harassment by the government or mine personnel.

Babies with very low or very high birth weight are less likely to survive. The graph shows the percentage of babies born at

dalvyx [7]

Answer:

Option C is correct.

The information provided clearly shows that the babies with average weights form a stable selection, the average is favoured.

Stabilizing selection is occurring because the average is favored.

Explanation:

Concluding Part of the question

A graph entitled Percentage of Babies born at Different Weights has weight in pounds on the horizontal axis, and percentage on the vertical axis. A small percentage of babies are born at the low and higher birth weights, and a greater amount are around 7 to 8 pounds.

Which statement is a valid claim that could be made using the data in the graph?

A) Directional selection is occurring because the graph favors an extreme.

B) Disruptive selection is occurring because the two extremes are favored.

C) Stabilizing selection is occurring because the average is favored.

D) Biodiversity variation is occurring because there is an increase in trait variation.

Explanation

Stabilizing selection represents a form of natural selection where the intermediate variants of a trait, that is the non-extreme trait values are the ones that ensure the survival and subsequent formation of stable population of the species with this average traits.

In this question, it is given through the data from the graph that babies with very low or very high weights are less likely to survive.

And it is logical as very low weight babies are most likely to be very weak, fragile and susceptible to being on the wrong side of natural selection and very high weight babies have all sorts of overweight issues plus the fact that they have to literally be squeezed out of the womb through a very narrow canal, really pushing their oversight bodies to its limits very early making them also susceptible to being on the wrong side of natural selection.

The average weight babies on the other hand do not experience any of the issues discussed in the last paragraph, they are usually healthy and thus have a high survival rate. So, it is evident to see that the population of babies stabilizes based on a particular non-extreme trait value (baby weight) through stabilizing selection.

Hope this Helps!!!

All cells come from other cells. New cells are created by a process called cell division. To start cell division, a cell grows b

garik1379 [7]

Answer:

c. When a rose bush cell divides, it copies its parts then divides into two cells and

d. The bacterium was formed when another bacterium divided

Explanation:

C is correct because the cells inside are part of a larger being (the rose bush), when they divide they are simply creating more cells (hence making the rose bush grow).

D is correct because bacterium are unicellular organisms, meaning they are themselves single cells that are organisms, unlike the rose bush consisting of many cells.
