Answer:
D: Helicase breaks hydrogen bonds in the template strand, DNA polymerase adds nitrogen bases
Explanation:
DNA replication is the process whereby DNA content is duplicated. This process of DNA replication is carried out with the aid of certain enzymes. Two of those important enzymes as stated in this question are DNA Helicase and DNA polymerase.
- DNA Helicase is the enzyme that breaks the hydrogen bonds that holds the two DNA strands in the molecule together. This separates the double-stranded DNA into two single strands.
- DNA polymerase is another enzyme that which carries out the nucleotide synthesis. DNA adds nitrogen bases to the new DNA strand based on what it reads on the DNA template

Explanation:
1. List the major ways in which humans are damaging the environment
2. Floods can devastate an ecosystem, however they can also have a positive impact. Please explain the positive impacts major floods can have on the ecosystem.
3. How do seasonal changes in temperature, water availability and sunlight affect ecosystems?
4. Propose 5 ways that humans can help minimise the negative effects both natural events and human impact can have on ecosystems.
Answer:
1. The large number of the pollution going into the air becaue of overfarming, and the high demand for unrenewable resources.
2. The positive impacts that floods can have is that they can water plants for places in drought like places such as California. For areas that are vastly dry, rain could be essential to humans, plants and animals in need of it.
3. These changes affect the ecosystem puts the ecosystems in a rather different situation than the ecosystem and those supported by it to adapt to the newcomings occuring of different seasonal changes and much more.
4.
-There can be alternatives to not destroying unrenawable resources.
-Use electrical cars that don't pollute the air.
-Be resourceful with their water and don't use more than needed.
-don't litter.
-recycle.
In which situation would osmosis most likely occur
The case in which osmosis occurs is that when there is a selective permeable membrane is present and it allows only selective substances to pass through the channel.
What is osmosis?Osmosis is the process in which molecules of the solvent pass via a semipermeable membrane from a lower concentrations to higher concentration or from less concentrated solution to high concentrated solution. In the process of osmosis movement of water takes place.
There are mainly three types of osmosis and these are hypertonic, hypotonic, and isotonic. The process of osmosis is passive transport as water moves from low solute concentration to high solute concentration.
Osmosis is also known as diffusion of water or solvent via a membrane which allows only selective substance to go across the channel. The process of osmosis does not require ATP because it is a passive process.
Therefore,The case in which osmosis occurs is that when there is a selective permeable membrane is present and it allows only selective substances to pass through the channel.

Which forms of energy are used when air is warming in the sunlight? Select all that apply.
Select one or more:
a. Light
O b. Electrical
c. Thermal
O d. Mechanical
Answer:
A and C
Explanation:
The sun itself is light energy and the heat that you feel from the sun is thermal energy.
Light and Thermal energy is used when air is warming in the sunlight.
Energy is emitted by the sun some of which is radiated back and some enter the earth.Solar energy is created by nuclear fusion that takes place in the sun.What is energy?The capacity or power to do work, such as the capacity to move an object of a given mass by the application of force. Energy can exist in a variety of forms, such as electrical, mechanical, chemical, thermal, or nuclear, and can be transformed from one form to another. Energy is a conserved quantity.The law of conservation of energy states that energy can neither be created nor destroyed only converted from one form of energy to another.Hence, A and C option are correct.
