Answer:

Hi dude

This means farming that not only produces food, jobs and economic well-being, but also creates cultural, social and environmental benefits. Agroecology also protects and provides ecosystem services like pollination, natural pest control, nutrient and water cycling and erosion control.

Agro ecology is the future of farming

Farming for the Future is a holistic farming approach that starts with building and maintaining the soil, because healthy soil is better able to retain water, reducing irrigation and water usage, and soil erosion and loss of top soil are reduced.

Agroecological methods can also help farmers cope with climate change by enhancing resilience. Agroecology has the explicit goal of strengthening the sustainability of all parts of the food system, from the seed and the soil, to the table, including ecological knowledge, economic viability, and social justice.

Each of the proteins involved in DNA replication plays an important role. If one of these proteins was not functional it would h
Masteriza [31]

Answer:

Explanation:

1. Topoisomerase is an enzyme helps in over winding Or underwinding of DNA during replication. Helps in the topological correction. So non-functional topoisomerase leads to tangled DNA and prevents replication..

2. Primases are the enzymes helps in the synthesis of short RNA sequences used as primers in replication. Non functional primase leads to no primer synthesis.  

3. DNA Polymerase is an enzyme helps in the addition of new nucleotide to the growing strand in replication. Non functional DNA polymerase prevents the strand growing as no new nucleotides were added.  

4. Helicases are the enzymes helps in the separation of double strands into single and helps in each strand to be copied. Non functional helicase leads to prevention of unwinding of strands and replication inhibition.  

5. ligase is an enzyme that joins nicks(small gaps) in the DNA strand by creating ester bond. Non functional ligase leads to unjointed gaps of lagging strand.  

6. Single strand binding proteins(SSB's) are the small proteins that binds to the single strands of DNA and holds them in a place not to get together while replicating. Non functional SSB's leads to parental strands come back together and prevents replication.

Which is most likely not a beneficial contribution made by biologists?
Elodia [21]

Answer:

The activity that does not represent a beneficial contribution made by biologists is to improve the durability of non-stick coatings (option C).

Explanation:

The development and improvement of non-stick coatings does not correspond to an activity within the field of biology. Anti-stick coatings, such as Teflon, are products developed through industrial activity.

Biologists' activity is focused on living organisms and their interaction with the surrounding environment. Improving arable soils and food quality, as well as increasing life expectancy are activities that fall within the field of study of biology and its related disciplines.

What is an acid?<br> What is the ph level of an acid?
Stels [109]

Answer:

• An acid is an electrolyte that hydrolyses in water to release hydrogen ions.

{ \rm{HA _{(aq)} \:  \:  {}^{ \dashrightarrow} _{ \dashleftarrow} \:  \:  H {}^{ + } _{(aq)} +A {}^{ - }  _{(aq)}}} \\

• pH level of an acid;

  1. Strong acid → 0 - 3.8
  2. Weak Acid → 4.0 - 6.7

A field of corn contains a certain amount of food energy. Compare the following situations and then answer the questions. Use th
trasher [3.6K]

Before assessing the two given cases, an assumption needs to be made about the digestion of the two types of food items, corn and beef. Let us assume that both get digested by expending same amount of energy by the human body. Let the amount of energy at producer level be an arbitrary X.

Case 1: Corn to human:

Since corn is at the producer level, it will have X amount of energy. The transfer of energy from corn to human will take place with a loss of 90% energy at the producer level. Hence the humans will receive 10% of X amount of energy.

Case 2: Corn to cow to human:

Since corn has X amount of energy, only 10% will pass to the next level, i.e. cow. So cow has 10% of X. Cow transfers only 10% of the energy that it has. Hence humans receive only 10% of 10% of X amount of energy.

It can be seen that humans receive more energy in case 1 than case 2. Hence we can say that it is more efficient for humans to feed on corn.
