Answer: DNA Ligase
Explanation:
During DNA replication, both the parental DNA strands are separated and act as templates for the synthesis of new strands. The formation of the new strands occurs in only 5'-3' direction and thus both the strands are synthesized in a different manner. One new strand with the template of 3'-5' direction will be synthesized continuously and is called a leading strand. The other strand with the template of 5'-3' direction will be synthesized discontinuously in the form of DNA fragments. These fragments are called Okazaki fragments and the strand is called a lagging strand. DNA ligase connects these fragments later to form a continuous lagging strand.
Therefore, DNA ligase is required for ligation of Okazaki fragments, and in absence of DNA ligase, the ligation of fragments will not occur and the newly synthesized strand will be discontinuous. However, if DNA ligase is not present in the reaction mixture, then the chances are that not all the newly synthesized DNA strands will be discontinuous. Only the DNA molecule with the lagging strand will be in the form of fragments.

deforestation
terrace building
Surface runoff is increased by deforestation.
What is deforestation?It refers to the removal of forest layers for non-forest-related projects.
Forest layers serve a variety of functions in the ecosystem, including reducing the rate of erosion or runoff by water.
Thus, removing forest layers will lead to an increase in the rate of runoffs in the ecosystem.

What law of energy can be applied to food processing?
The first law of energy can be applied in food processing whereby foods are converted from one form to another.
What is food processing?Food processing is the process by which food is converted from its natural state obtained from plants to a more edible and palatable state for consumption by humans.
The first law of energy states that energy cannot be created nor destroyed but can be converted to other forms.
Therefore, the first law of energy can be applied in food processing whereby foods are converted from one form to another.

dry lab evidence of evolution
Answer:no
Explanation: because it’s no
Answer:
The evidence for evolution
In this article, we'll examine the evidence for evolution on both macro and micro scales.
First, we'll look at several types of evidence (including physical and molecular features, geographical information, and fossils) that provide evidence for, and can allow us to reconstruct, macroevolutionary events.
At the end of the article, we'll finish by seeing how microevolution can be directly observed, as in the emergence of pesticide-resistant insects.
Calculate the area of land in hectares.
Note: 10000m^2 = 1hectares
if the school plan to cultivate plantain at the spacing of 4m * 4m of 80% of the land and pineapple at a spacing of 2m * 2.5m on 20% of the land, Calculate the number of plantain and pineapple planting materials that would be required for the farm.
Please help me.
Answer:
0.315 hectares
Explanation:
To get the answer, we use the area of a trapezium formula, which is ½ (a+b) h, where a and b are the parallel sides and h is the height.
So ½(90m+50m) 45m
½ × 140 × 45
70 × 45 = 3150m²
10000m²= 1hectare
3150m² = x
3150 ÷ 10000 = 0.315 hectares.

Unicellular organism are one celled but multicellular organisms are made up of many cells.
Explain the difference between unicellular and multicellular organization of organisms?As the name suggests, unicellular organisms are made up of only one cell and this single cell carries out all the essential functions that are needed for the survival of the organism like respiration, photosynthesis etc.
But in multicellular organization, the organisms are made of more than one cells and cells are grouped according to their functions. Each group is specialized for specific functions. Even in higher multicellular organisms the group of cells form specific types of tissues and further they form organs and organ systems which function more efficiently.

Which of the statements is true about heating up air in the lower atmosphere
Answer: Option (A)
Explanation:
The interior of the earth radiates a huge amount of energy due to the presence of molten heavy materials namely iron and nickel. This heat energy drives the plates to move over the mantle.
This radiated energy plays a significant role in increasing the temperature at the lower atmosphere. At the lower atmosphere majority of the air is concentrated due to its high density and are attached to the ground because of gravity.
This radiated heat energy then heats up this air particles that leads to an increasing air pressure and temperature.
