The correct answer for the question above is B,
Industrial agriculture increased our ability to obtain more food from the same area. Industrial agriculture is a form of modern agriculture that refers to industrialized production of crops, poultry, livestock and fish. The methods used are technoscientific, economic and political. For example today majority of American farmland is dominated by industrial agriculture.
Answer:
c and d.
Explanation:
a. the total amount of matter and energy increased.
b. the total amount of matter and energy remained the same.
c. matter and energy were lost each time they changed forms.
d. matter and energy were lost each time they changed locations,
As organisms feed within an ecosystem, energy flows from one trophic level to the other while matter is converted from one form to another.
However, less and less energy becomes available to support life as energy moves through the ecosystem from producers to consumers as a result of energy loss to the ecosystem. In addition, matters are also lost during conversion from one form to another.
Hence, matter and energy are lost each time they changed forms and locations.
Option c and d are correct.
Answer:
Mutalism
Explanation:
Mutalism is when both species benifit
Answer:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells.
Explanation:
Basically there are four processes that takes place under "MEIOSIS". And they are :
- Prophase
- Metaphase
- Anaphase
- Telophase
Prophase:
In prophase, chromosomes become visible and crossing-over occurs, then nucleolus disappears and the meiotic spindle forms, then the nuclear envelope disappears.The duplicated homologous chromosomes pair, and crossing-over (the physical exchange of chromosome parts) occurs.
Metaphase:
Metaphase process that separates duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During metaphase, the cell's chromosomes align themselves in the middle of the cell.
Anaphase:
Anaphase I begins when the two chromosomes of each bivalent separate and start moving toward opposite poles of the cell as a result of the action of the spindle.
Telophase:
In telophase a homologous chromosome pairs reach the poles of the cell, nuclear envelopes form around them, and cytokinesis follows to produce two cells. After cytokinesis, each of the two progeny cells has a nucleus with a haploid set of replicated chromosomes.

See explanation
Explanation:
There are three main aspects of photosynthesis
(i) Absorption of light energy by chlorophyll.
(ii)Photolysis of water
(iii) combination of water and CO2 to form carbohydrates.
The second and the third aspects of photosynthesis are controlled by the availability of water. Plants absorb water from the soil through their root hairs and it moves up to the leaves by capillary action.
Hence, if there is no rain (drought), the soil will lack water and so does the plant thereby hindering the uptake of water for the second and third stages of photosynthesis.
the Arizona poppy, lie dormant during drought only to germinate, grow, flower, and yield seeds a few weeks after the rains return.
