Explanation:
DNA replication begins when the double helix untwists and breaks in half between the nitrogen bases. What are the next two steps in the process of DNA replication?
Answer:
Step 1: Before DNA can be replicated, the double stranded molecule must be “unzipped” into two single strands. ... Step 2: Primer Binding. The leading strand is the simplest to replicate. ... Step 3: Elongation. ... Step 4: Termination
The DNA gets unzipped during DNA replication after the double helix unwinds. Each original DNA strand acts as a template for the new strands when the strands are split in two. The bases on either half of DNA are then paired with the nitrogen bases that have sugar and phosphate. In order to adhere to the principle of base pairing and guarantee that the base sequence is maintained, the molecules present in the new strand must be complementary to those found in the original strand. DNA replication ends with the formation of two identical strands.

Explanation:
The table shows the potential energy and kinetic energy of a skier at two different positions on a hill.
Position and Energy
Position (above ground) Kinetic Energy Potential Energy
100 meters 0 units 50,000 units
60 meters 20,000 units ?
What is the potential energy of the skier at a height of 60 meters above the ground?
30,000 units, because total energy decreases
70,000 units, because total energy decreases
30,000 units, because total energy remains unchanged
70,000 units, because total energy remains unchanged
15,000 units, because total energy is 50,000 units
Mark me brainliest
According to law of conservation of energy, energy remains conserved. It only transforms from one form to another.
The total energy here is the sum of kinetic and potential energy.
At 100 meters, total energy = Kinetic energy + potential energy = 0 units + 50000 units = 50000 units
At 30 meters, total energy = Kinetic energy + potential energy = 35000 units + x units = 50000 units
x units = 15000 units
Thus if the kinetic energy has increased from 0 to 35000 units, the potential energy must decrease from 50000 to 35000 units to keep the energy conserved.wer:

Look at the diagram of the rock cycle below.
Which part of the cycle is missing?
A.
sedimentation
B.
melting
C.
crystallization
D.
mineral integration
From the diagram of the rock cycle the missing part is ( B ) ; Melting
Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.
Magma is released to the earth surfaces during volcanoes therefore the missing term in the rock cycle is melting
Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.

What is the relationship between changes in air pressure and wind speeds?
A: When a high- and a low-pressure air mass are far apart, air moves quickly from low to high pressure.
B: When a high- and a low-pressure air mass are far apart, air moves quickly from high to low pressure.
C: When a high- and a low-pressure air mass are close together, air moves slowly from high to low pressure.
D: When a high- and a low-pressure air mass are far apart, air moves slowly from high to low pressure.
Answer: Option A
Explanation: When a high- and a low-pressure air mass are far apart, air moves quickly from low to high pressure. This is because air moves from areas of low pressure to areas of high pressure due to differences in air pressure.
In low pressure, air rises and rotates fast in the high atmosphere, forming fast winds. In high pressure, the air sinks instead of rising, forming slow-moving air currents or slow wind. A low pressure system brings rain, snow, and high winds, while a high-pressure system brings cold air.

A class is learning about the evaporation step in the water cycle using a simple model. The model consists of a 1-L container of water. When the container is open, and it receives sunlight, the water can freely evaporate from the container. The students design an experiment using the model. In the experiment, the container will be filled and left open outside from dawn until dusk at different times of the year. The students will run the experiment only on days with clear weather. As a basis of their experiment, the students make an assumption that more water will evaporate from their model when more solar energy is present. Which of the following is a result that the students could predict in order to test their assumption?
A.
Equal amounts of the water will evaporate on summer days and winter days.
B.
Less of the water will remain in the container after one day in summer than after one day in winter.
C.
Less of the water will remain in the container after one day in winter than after one day in summer.
