The lytic cycle can change to the lysogenic cycle in the given manner discussed The lysogenic cycle allows a phage to reproduce without killing its host. Some phages can only use the lytic cycle, but the phage we are following, lambda ( λ), can switch between the two cycles.
The lytic cycle:The lytic cycle infects a bacterium, captures the bacterium to make lots of cycles , and then kills the cell by making it explode (lyse).
The lysogenic cycle:The cycle infects a bacterium and inserts its DNA into the bacterial chromosome, permitting the cycle DNA (now called a pro phage) to be copied and passed on with the cell's own DNA.
Can lytic become lysogenic?During lysogeny, the pro phage will consist in the host chromosome until induction, which in the causes excision of the viral genome from the host chromosome. After induction has resulted the temperate phage could proceed through a lytic cycle and then undergoes lysogeny in a newly infected cell.
How lytic cycle is different then lysogenic cycle?The important difference between lytic cycle and lysogenic cycle is that lytic cycle destroys the host cell on contrary lysogenic cycle doesn't destroys the host cell. Where as Viral DNA destroys the host cell DNA and arrests cell functions in the lytic cycle.

Answers
In the case of humans, we have 23 pairs of chromosomes which determine the details of our genetic makeup.
What are chromosomes?Chromosomes are long, linear structures in the nucleus of a cell that carry the genetic information of an organism. Chromosomes are made up of DNA, the molecule that carries the instructions for the development, function, and reproduction of an organism. Humans have 46 chromosomes arranged in 23 pairs, with each pair consisting of one chromosome from the mother and one from the father. Chromosomes contain genes, which are sequences of DNA that encode specific traits or characteristics, such as eye color, height, and susceptibility to certain diseases.
The specific arrangement and combination of genes on chromosomes determine an individual's unique genetic makeup, and changes in the DNA sequence can result in mutations, which can have a range of effects on an organism's development and function. Chromosomes play a crucial role in cell division and reproduction, as they are responsible for passing genetic information from one generation to the next.

The building is being help up by cells, how?
Answers
The smallest unit of life, cells serve as the basic building blocks for all living things. Living organisms' growth, development, and functionality are all governed by their cells.
How cells are crucial in the building blocks of all living organisms?They may carry out a range of tasks because they are made up of several organelles, including the nucleus, mitochondria, endoplasmic reticulum, the Golgi apparatus, and other parts. The synthesis of proteins and other molecules necessary for the operation of the organism, as well as the creation of energy and the storage of nutrients, all take place within the cells. Moreover, cells enable communication between various components of the organism, allowing it to react to its surroundings.
Why do mitochondria exist?Eukaryotic cells contain organelles called mitochondria, which are the sites of cellular respiration and generate ATP as a type of energy. Mitochondria are organelles found in the cells of eukaryotes, which are organisms whose cells contain a nucleus and other organelles surrounded by a membrane. Mitochondria are the powerhouses of the cell, responsible for producing energy in the form of adenosine triphosphate (ATP). They do this through a process called cellular respiration, in which glucose is broken down with oxygen to produce ATP. ATP is then used to power a variety of cellular processes such as muscle contraction, protein synthesis, and cell signaling. In addition to producing energy, mitochondria also play a role in other cellular processes such as calcium signaling, apoptosis, and cell metabolism.

A student put together the experimental setup shown above. The selectively permeable membrane is permeable to both types of solute molecules shown.27. Do you expect the distribution of solutes on each side of membrane to changeover time? Explain.28. Redraw the apparatus making an inference as to where molecules C and D willbe when it reaches equilibrium.29. Once equilibrium is reached will the molecules continue to move? Explain.
Answers
First of all, the problem says that the membrane is selectively permeable.
Permeable means that it allows molecules to pass from one side to another (and vice-versa).
On the other hand, we have the concept of selectively, which means that not all types of molecules are allowed to cross through the membrane, but in this case, it also says that the membrane it's permeable for both molecules.
So, in this case:
27) Yes, in order to reach the equilibrium, the molecules will move, until there is an equal amount of each of them on both sides of the membrane.
28) The important thing here is not how many molecules of each type you draw on each side, but the amount of them should be the same on both sides. Take into count that we are not having in count the interaction between the molecules either.
29) Yes the will, because of the permeable property of the membrane. This is the reason why this equilibrium it's called a dynamic equilibrium.

tall heterozygous pea plants were crossed and the resulting seeds grown. Out of 360 plants, 270 were tall and 90 dwarf. What describes the expected genotype resulting from the cross
Answers
Answer:
This question lacks options, the options are:
A. All 270 tall plants were heterozygous
B. All 270 tall plants were homzygous.
C. Only 90 plants were homzygous.
D. All dwarf plants were homzygous.
The answer is D.
Explanation:
This question involves a single gene coding for height in pea plants. The allele for tallness (T) is dominant over that of dwarfness (t). This means that a dwarf plant can only be homzygous recessive (tt) while a tall plant can either be homzygous (TT) or heterozygous (Tt).
According to the question, two tall heterozygous pea plants were crossed i.e. Tt × Tt. Based on this cross, a phenotypic ratio of 3:1 is expected, which is in accordance with the 270 tall plants and 90 dwarf plants (360 total) that was obtained in the cross. Since dwarfism in pea plants is a recessive trait, this means that all the dwarf plants produced in this cross (90) were homzygous (tt).
The expected genotype resulting from the cross was that all dwarf plants were purebreed.
So, according to the given information, there is a cross between Tt × Tt. A phenotypic ratio of 3:1 is desired, which is in accord with the 270 tall plants and 90 dwarf plants (360 total) that were got in the cross.
Since dwarfism in pea plants is a different feature, this means that all the dwarf plants produced in this cross (90) were (tt).

Predict what will happen when a piece of algae (simple plant) from the ocean is placed in a beaker of fresh water. Be sure to include the appropriate vocabulary while you are explaining your answer including the salt and freshwater environments compared to the algae. (Hypertonic, hypotonic, isotonic).
Answers
When an algae from the ocean is placed in fresh water, the water environment around the algae will become hypotonic in comparison to the algae's cytoplasm.
What makes the ocean water hypotonic?The high concentration of salt and other solutes in the ocean water creates a hypertonic environment for the algae, while the low concentration of solutes in the freshwater creates a hypotonic environment.
This change in osmotic pressure will cause water to move into the algae cells, causing the cells to swell. If the water uptake becomes excessive, the cells may burst and the algae may die.
However, if the algae is able to adjust its internal salt concentration, it can survive in freshwater. This process is called osmoregulation.

Answers
A substance requires energy to move across a membrane when it moves from (C) Low concentration to High concentration
The process of moving a substance across the cell membrane from high to low concentration is known as passive transport, which does not require energy. Active transport, on the other hand, is the process of moving a substance from low to high concentration, which requires energy.
The movement of molecules against their concentration gradient (low to high concentration) requires an energy source, which is usually in the form of ATP (adenosine triphosphate). Low concentration to High concentration. During active transport, the substance moves against its concentration gradient, which means it moves from an area of lower concentration to an area of higher concentration.
This process requires energy, which is provided by ATP. Active transport is responsible for the uptake of nutrients, such as glucose and amino acids, in cells. The process of active transport is crucial in maintaining the proper concentration of ions in cells. Additionally, active transport is essential for maintaining the pH of cells and the function of enzymes. Overall, active transport is an energy-intensive process that is vital for cellular homeostasis and function. The correct answer is C.

What happens when the freshwater becomes acidic?The freshwater ecosystem differs from the oceanic saltwater ecosystem in that freshwater contains phytoplankton, edible fish, and so on. The fresh water has a normal pH, but the pH decreases and induces acidity when the water is polluted with different chemicals, such as nitrogen oxide, sulfur dioxide, etc.
When acid rain happens due to man-made pollution, this further adds acidity to the fresh water, and as a result, the species that live in the lake are not able to live and breathe properly due to a lack of oxygen. The acidity in the table increased year after year from 1989 to 1996.
