3. A strain of cells undergoes a mutation that increases the permeability of the inner
mitochondrial membrane to hydrogen ions.
a) What effect would you expect this mutation to have on the process of cellular
respiration? 12
b) Assuming the mutant cells can survive, how might the metabolic requirements of
these cells differ from those of a non-mutant strain of the same variety? 12
Answers
A mutation that involves the permeability of the inner mitochondrial membrane to protons (H+) will affect the amount of ATP. If mutant cells can survive, then they will need more energy to create a suitable gradient.
Cellular respiration is a series of metabolic reactions by which aerobic cells can generate energy in the form of ATP by using the chemical energy stored in the foods.
Cellular respiration can be divided into three sequential stages: glycolysis, the Krebs cycle (also called the acid citric cycle) and oxidative phosphorylation.
During oxidative phosphorylation, the transport of electrons across the inner mitochondrial membrane is coupled to the generation of an electrochemical proton (H+) gradient, which is then used to generate ATP by means of a protein complex known as ATP synthase.

the presence of a lophophore in a newly discovered species would suggest that the species ________.
Answers
Answer: the answer is has an exoskeleton
The lophophore is the feeding organelle in aquatic organisms. Its presence in a species suggests that the species is a suspension feeder. Thus, option D is correct.
What are lophophores?
Lophophores are the feeding organelles present in the marine invertebrates like Brachiopoda, Hyolitha, etc., of the Lophophorata group. They are used for respiration, brooding, and collecting food.
Suspension feeders use these lophophores to collect and feed on the suspended organic matter and particles in the water. Lophophorates are a major example of suspension feeders.
Therefore, the presence of the lophophores suggests the species to be a suspension feeder.

Imagine that you are managing a large wildlife preserve that was formerly a cattle ranch. You know from historical accounts that wild sheep used to live there, but they were hunted until the local population was exterminated. After doing some research to determine what might be an appropriate starting population, you introduce them. Food is abundant and they have no natural predators. You then spend several years graphing the number of individuals (on the vertical axis) against the number of generations (on the horizontal axis). By the 10th generation, the population begins to reach carrying capacity.

What BEST defines this mathematical model used in population studies?
Answers
The mathematical model used in this population study is known as the logistic growth model.
What is logistic growth model?The logistic growth model is a mathematical model that is used to describe the growth of a population over time. It is based on the idea that the growth of a population is limited by resources such as food, habitat, and space, and that as the population grows, the rate of growth begins to slow. This results in a curve that starts out steep and then levels off as the population approaches its carrying capacity, which is the maximum population size that can be sustained in a particular environment.
In the scenario described, the population of wild sheep is introduced to a wildlife preserve where food is abundant and there are no natural predators. This means that the population is able to grow at a relatively fast rate, but as the population increases, it begins to approach the carrying capacity of the preserve. At this point, the rate of growth begins to slow, and the population levels off.
This is reflected in the graph, which shows the population increasing rapidly at first and then leveling off as it reaches carrying capacity. The logistic growth model is often used to understand and predict the growth of populations in a variety of contexts, including agriculture, biology, and economics.

Explanation:
Answer:
While following a similar education and career path to that of information systems managers and computer programmers, computer and information research scientists have a specific subset of skills and duties that sets them apart from other computing professionals.
Information research scientists work to advance the field of computing and create new computing-based solutions to problems in countless industries. Their role is as a trailblazer: The development and design of new digital technologies, such as data mining software, is the quintessential duty of a computer research scientist.
Repurposing older technology to work in specific contexts is another frequent activity of a research scientist. They put the “science” into computer science — they research, test, and create, whereas other CS disciplines might focus on information systems management or programming software. Notable historical figures in computing, such as Ada Lovelace and Alan Turing, would be classified as computer and information research scientists today. The advancement of the field is the mission for those in this career.
Due to the broad applicability of computing technology to various fields, computer and information research scientists can be found in almost every industry. From food service to aerospace engineering, nearly every line of work can use these research scientists. As a result, duties for this career can vary greatly.
Many computer research scientists can be found in the field of robotics, where software combines with mechanical hardware to create machines that are more efficient and viable in commercial use. Others might find themselves in the medical field, creating new systems for collating and analyzing patient data. The ubiquity of computing technology means that a typical day for a computer and research scientist is almost impossible to define, and this makes the field quite exciting and dynamic.
There are some common trends that can be defined, however. Computer and information research scientists should expect to become familiar with machine learning and artificial intelligence. This emerging field of computing is perceived as the iconic technology of the future. The demand for computer scientists experienced in machine learning and AI is growing fast. As research scientists, those in this career will be hard-pressed to avoid work that involves AI. Many roles in academic and private settings focused on the research and advancement of artificial intelligence can be found. This field is slowly dominating the focus of many different industries: Automotive, health care, marketing, and even private military companies all have their hands in the world of AI, and that list is growing bigger each day.
The basic idea of the occupation is that information scientists invent new computing technologies in response to various needs. Invention naturally leads to technological advancements in many different lines of work.

Summarize the lytic cycle. (1 point)
The viral DNA incorporates itself with the host cells and replicates whenever the host cell replicates itself.
A virus copies its genetic material and then splits its cell membranes in half to form identical viruses.
A virus lays eggs on the host cell’s protein coat, which then hatch and move on to infect other cells.
A virus injects its genetic material into the host cell, copies itself, and then forms new viruses that burst out of the host cell.
Answers
Answer: A virus injects its genetic material into the host cell, copies itself using the host's structures and resources, and then forms new viruses that burst out of the host cell
The lytic cycle is one of the two main life cycles of viruses, the other being the lysogenic cycle. In the lytic cycle, a virus infects a host cell and hijacks its cellular machinery to replicate and produce new virus particles, or virions.
The correct option is D .
The lytic cycle is rapid and results in the destruction of the host cell. It is often associated with acute infections, where the symptoms of the infection are more severe and appear relatively quickly. Examples of viruses that follow the lytic cycle include the flu virus (influenza), the common cold virus (rhinovirus), and many bacteriophages that infect bacterial cells.
The lysogenic cycle, on the other hand, is characterized by the integration of the viral genetic material into the host cell's genome, allowing the virus to remain dormant for a period before switching to the lytic cycle.
Hence , D is the correct option

Answer:
The disadvantages for both cells are that neither is an accurate representation of the cell themselves, or the processes. The first cell doesn't tell us exactly what phases the cell is currently going through, and the cell doesn't go through is phases through grey arrows either. However, it does tell us what the phases look like, and the process of how the cell goes through them. The disadvantages of the second map is that, it doesn't show what the phases look like, the advantages are that tells us what the phases are and what comes before and after them, while showing how this occurs in a cycle and keeps going until senescense.
