Answer:

DNA primers

Explanation:

PCR uses short DNA segments called as primers. These primers become paired with the template DNA strands and are being elongated by the DNA polymerase enzyme (Taq polymerase). On the other hand, in vivo DNA replication does not use the DNA primers. Primase is the enzyme that makes RNA primers with free 3' OH end which is then elongated by DNA polymerases. The RNA primers are synthesized when the primase enzyme makes a short RNA copy of the DNA template strand.

iVinArrow [24]

Answer: 6CO2 + 6H2O -> C6H1206 + 6O2

Explanation: This is a balanced chemical equation for photosynthesis. In photosynthesis, six molecules of carbon dioxide react with six molecules of water in the presence of sunlight to form one molecule of glucose and six molecules of oxygen. Photosynthesis is a process by which green plants manufacture their own food using sunlight. Plants cells have an organelle known as chloroplast which contains chlorophyll a green pigment that traps energy from the sun. The energy trapped by the chlorophyll is used by plants in the presence of carbon dioxide and water to drive the synthesis of glucose with the release of oxygen as the by-products.

Which phase of a population growth curve is characterized by a slowing of population growth as the carrying capacity is being re
jarptica [38.1K]

Answer:

Lag Phase

Explanation:

In logistic growth, lag phase is characterized by a slowing population growth because at that moment the cells are metabolically active and  are only increasing in cell size.

Let consider a bacterial growth during it lag phase. In the lag phase, bacteria adapt themselves to growth conditions, that period of time, they are still maturing and are yet to divide.

As such, the phase of a population growth curve is characterized by a slowing of population growth as the carrying capacity is being reached is known as Lag Phase.
