The correct answer is B. Modern technology allowed for larger expanses of land to become cultivated, so farming took over many natural areas that were important for wildlife.
Explanation:
In the last decades, the creation of agricultural technology has increased the efficiency of growing crops. This means now, all the process is more efficient, which leads to more products to be sold and an increase in profit. However, the possibility of large scale agriculture has caused more land is used for this purpose. This often implies natural ecosystems such as forests are destroyed and the land of these ecosystems, which is usually rich in minerals, is used for extensive agriculture. This is a negative consequence of agricultural technology as natural areas important for wildlife are taken for human profit.
None of the bove. Soil erosion occurs due to deforestation, water, wind and tillage of the land farms. It is the removal of the top layer of the soil, and leads to poorer quality of soil, called a soil disruption. This can be avoided by using proper farming techniques and afforestation.
Kile should know the answer because of the morphology (part of biology that studies the estructure and the form of something). The plant cell presents a rectangular form, while the animal's cells presents a round form.
There are other main differences. As their parts and the size. Before I explain that remember that a cell can be of two types eukaryotic (cell with nucleus) and prokaryote (cell with no nucleus). In the other they can be neurons, nefrons, etc...
The plant cell contains for example chloroplasts, cell wall and vascuoles; while animal's don't. Both of them have nucleus, cell plants are generally larger than animals. Those are the main differences.
Thankyou.

<u>Answer:</u>
Recent evidence suggest that feathers evolved from scales and suggest that 'feathers and pycnofibers' could be homologous.
<u>Explanation:</u>
- One of the major difficult issue related to bird evolution is the evolution of feathers.
- Feathers are considered as the most 'complex integumentary structures' which are found in vertebrates.
- Evolutionary developmental biology suggests that the 'planar scale structure' is been modified for developing into feathers by 'splitting' to form web like structures.
- Scales and Feathers consist of 'two distinct form of keratin' so it was thought that 'each type was exclusive skin structure' but recent study suggests that they are developmental expressions of same skin structures.
Answer:
Two
Explanation:
Because there is two cells in each thing
