Yes, I can help you with this a food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.
Every food chain begins with a producer. The food chain shown below uses arrows to show the transfer of energy and nutrients, which is always from the consumed to the eater.
An ecosystem's only conduit for the flow of matter and energy is represented by a food chain. An essential conceptual tool for depicting the feeding connections among species within a group is the food web.
All the interconnected and overlapping food systems in an ecosystem are combined to form a food web. The linkages or interconnections between objects are described by food webs. Energy is transferred between the species in food webs from producers to consumers. Energy is used by organisms to carry out demanding tasks.

Cell respiration begins with one molecule of glucose and produces2 ATP and Lactic Acid36 ATP2 pyruvate2 ATP
The cellular respiration is the process in which the cell frees the energy stored within glucose and stores it in ATP molecules. This process is aerobic, which means that this process needs oxygen to occur.
There are three stages in this metabolic path:
First stage: Glycolysis, during this process, glucose is broken down to from 2 pyruvate molecules and 2 ATP molecules.
Second stage: Krebs cycle, during this process the pyruvate molecules obtained at the end of the glycolysis undergo a series of changes and the resulting molecule is acetyl-CoA, the energy released during this process is stored into 10NADH, 2 FADH₂, and 2 ATP molecules.
Third stage: Electron transport, this last stage occurs in the membrane of the mitochondrion, at the end of this process, 32 to 34 ATP molecules are created.
The net harvest of the complete process is 36 to 38 ATP molecules.
So, the correct option is 36 ATP

What is the difference between ground layering and air layering?
Layering is a method in which a branch of the plant is covered with some material and supplied water to produce roots.
They are done in two ways:
1.) Ground layering
2.) Air layering
Ground layering or mound layering is the typical propagation technique for the popular Malling -Merton series of clonal apple root stocks, in which the original plants are set in the ground with the stem nearly horizontal, which forces side buds to grow upward.
Air layering is a method of propagating new trees and shrubs from stems still attached to the parent plant. The stem is wrapped with damp moss to encourage roots to form.
The main difference between them is for soil layering, lower stems are bent to the ground and covered with moist soil of good quality. For air layering, a branch is deeply slit and the wound is covered with a ball of earth or moss and kept moist until roots develop; the branch is then severed and transplanted.

(b) To genetically engineer the original cell so that it would glow, the scientists had to obtain a suitable
gene.
(i) Describe the stages that a scientist would complete to obtain this gene.
Answer: See Below
Explanation:
1. The scientist would need to identify the gene for a protein that would make it glow. For example Aequorea victoria, the jellyfish that produces green fluorescent protein (GFP) is the most common type of fluorescent tag use in biotechnology. This would be done by completing genetic sequencing to identify the gene of interest from the jellyfish cell.
2. The gene could then be amplified through PCR. Assuming this is a bacterial cell, a vector such as pUC19 could be used. The vector and the PCR amplified product would have to be digested. A double digest is recommended to ensure the gene inserts in the proper conformation.
3. Heat shock the plasmid into the cell and proceed on to Blue/White screening to identify which cells contain the gene of interest. You can then isolate and grow the culture containing the GFP gene and induce with IPTG to produce the protein that would make it glow.
Alternatively you could buy a pre-made plasmid from AddGene containing the GFP gene for 75$, complete a miniprep on the cells and heatshock. Either way works.

Why do you think multiple replication bubbles form during the process of dna replication in eukaryotic cells?.
Eukaryotic DNA can have multiple replication bubbles to speed up the process of DNA replication.
The process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules is known as DNA replication. Replication is necessary because when a cell divides, the two new daughter cells must have the same genetic information, or DNA, as the parent cell. Each DNA molecule contains one strand of the original DNA molecule and one strand that has been synthesized (created). As a result, DNA replication is referred to as semiconservative.
It is an unwound open region of the DNA helix from which DNA replication takes place. DNA polymerase continues to add nucleotides to unwound DNA strands. The replication bubble is modeled after a zipper that is unzipped in the center, resulting in a small open bubble-like structure.
