What is the difference between permanent gases and variable gases in the atmosphere?
Answers
Answer:
the difference is that permanent gases have larger residence times and Variable gases have shorter residence times
the difference between permanent gases and variable gases in the atmosphere is permanent gases are gases that have a very low dew point.
What are the characteristics of the atmosphere?The Earth's atmosphere is basically composed of a mixture of gases, being 78% Nitrogen, 21% Oxygen and 1% Argon. In addition, traces of carbon dioxide, water vapor and other gases are found, but in very small amounts.
In this way, permanent gases are gases that have a very low dew point.

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.

A scientist wants to determine the age of a rock. The rock contains an index fossil and an ancient relative of a living organism. Which is more useful for dating the rock, and why?
Answers
Answer: Ancient Relative of a living organism
Explanation: Ancient Relative because by using the index fossil, you are also using the law of superposition. This law does not give you an accurate/specific date but instead the order they are in (i.e me saying i am older than my siblings compared to me saying i am 2 years older than them). By using an ancient relative of a living thing then we can see its phylogenic tree and measure around how old it is. Fossils also hold carbon and chemicals in there bones which allows us to use carbon dating. Carbon dating is an accurate way of measuring age.

Why is it that cancer does not form every time there is a mistake during the cell cycle?
Answers
Answer:
Cells will actually kill themselves through a process called apoptosis, or it will be attacked and killed so it doesn’t spread. For example, when you are exposed to the sun for a long period of time, the solar radiation can mess with your skin cells. That’s why you get sunburned: the cells dry up and fall off. Otherwise, you could get skin cancer

Most of the world's iron ore, including that found in northern Minnesota, formed during the middle Precambrian period, ranging in age from 1.8 to 2.5 billion years old. They are composed of alternating layers of iron-rich material, most often magnetite or hematite, and silica. These iron oxide minerals formed on the ocean floor, creating the banded iron deposits you see here. What was the source of the oxygen that helped to produce these deposits?
A) The oxygen that was released into the atmosphere as a by-product of photosynthesis caused iron deposits to oxidize creating the iron oxide minerals.
B) Photosynthetic organisms making oxygen as a by-product of photosynthesis and the oxygen reacted with the iron dissolved in seawater to form iron oxide minerals.
C) The decomposition of carbon-based life forms in the oceans released oxygen and carbon dioxide. These gases reacted with the iron deposits forming the minerals mentioned.
D) In Earth's early biosphere, there were not organisms that underwent aerobic cellular respiration and an excess of oxygen built up in the atmosphere. This oxygen reacted with iron deposits to form iron oxide minerals.

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.
