Describe the synthesis of the lagging strand of DNA
Answer:
On the lagging strand, DNA synthesis restarts many times as the helix unwinds, resulting in many short fragments called “Okazaki fragments.” DNA ligase joins the Okazaki fragments together into a single DNA molecule. Helicase opens up the DNA at the replication fork.
The yellow ring inside the bacterial cell represents the bacterial DNA. Why does this structure
disappear by step 3 of the lytic cycle?
Answer:
Explanation The bacterial DNA structure will disappear because of ; The usage of the ribosomes of the bacterial cell by the nucleic acid injected by the virus.
The lytic cycle which is one of the cycles of viral reproduction is the cycle which leads to the breakup of the DNA of the cell ( i.e. destruction of the host cell and its membrane).
Therefore the yellow ring inside the bacterial cell will disappear by step 3 after which the nucleic acid is injected into the host cell by the virus .
Hence we can conclude that the bacterial DNA structure will disappear because of the usage of the ribosomes by the nucleic acid from the virus

Discuss why photosynthesis is important for humans and life?
Answer:
Here is my answer.
Explanation:
The process of photosynthesis is essential to all living organisms, because it is the primary source of oxygen in the atmosphere. As a result, the carbon cycle could not occur. Plants and oxygen-requiring life would not survive without photosynthesis. Photosynthesis is the process of making food from light, carbon dioxide, and water in the air: It is the main energy source for green plants and trees. Photosynthesis produces oxygen, which we need for survival. Without photosynthesis, the world would have little to no oxygen.
Let me know if you need help :)
Answer:
It provides human's and organisms with food and energy.
Explanation:
Not only does photosynthesis produce crops such as wheat and carrots which are primary foods in our diets, it also is responsible for heat and many of the materials we use (such as cotton for fabric). Photosynthesis also provides light and electricity through reusable energy.

The first question says “Use the T chart to list at least 3 differences (Ecological Principles) between the movements of energy and matter through the ecosystem” I need help really bad on this so I’d highly appreciate is someone would help me on this (You have until May to answer these questions + I will be providing 50 points)
The differences between the energy flow and matter cycling depend on the number of trophic levels in the ecosystem.
What do you mean by Ecosystem?The Ecosystem may be defined as the area or place where organisms of different species live and interact with each other in a well-defined way.
The first key difference between energy flow and matter cycling is that the energy flow shows the transmission of energy from one trophic level to the other in the food chain, while matter cycling shows the cycling of elements throughout the living and non-living parts of the ecosystem.
Energy flow always follows a fixed and definite pathway, while matter cycling randomly works in the ecosystem.
As energy moves through an ecosystem, it changes form but no new energy has been synthesized. Matters flow throughout the ecosystem, atoms are rearranged into various other molecules as per requirement but no new matter is created.
Therefore, the differences between the energy flow and matter cycling depend on the number of trophic levels in the ecosystem.

1. which of the zones discussed the experiences of photosynthesis.
2. what are the deepest ocean zones.
3. what ocean zone covers more than 50% of the earth's surface
Answer:
1, The top zone is the euphotic or sunlit zone. This is the ocean zone that sunlight penetrates. Because this zone gets sunlight, photosynthesis can occur and plants can grow here. The sunlit zone goes down to about 660 feet.
2. The deepest part of the ocean is the Hadalpelagic Zone. It is also known as the trenches. It goes from 6 000 to approximately 11 000 metres

if a species has a wide range of tolerance, will it dominate a habitat in low pollution or high pollution? why?
A species with a wide range of tolerance can dominate most habitats due to its ability to adapt.
What is a wide range of tolerance?A wide range of tolerance is the ability for an organism to tolerate low or high levels of abiotic contamination in it's natural habitat. This means that the organisms in question show a high level of adaptability and are able to survive in hostile environments. This allows them to remain dominant in most habitats despite contamination values.
