what factors do you predict might influence the likelihood of mutations occurring in viruses?
The factors which might influence the likelihood of mutations occurring in
viruses is Spontaneous nucleic acid damage and replication inhibition.
Viruses are pathogenic micro-organisms which mutate rapidly than the
humans do. Its ability to mutate very rapidly inside the host cells is what
makes it unique and deadly.
Factors which might influence mutations in Virus include nucleic acid
damage and replication inhibition. When this occurs, the virus isn't able to
mutate thereby causing less damage to the host.

How would a biomagnification “pyramid compare with an energy pyramid?
Answer:
Energy pyramid depicts flow of energy in the ecosystem: source of all energy in ecosystem is the SUN. Producers are only organisms in ecosystem who can trap the solar enrgy. So base of energy pyramid is always wide. A biomass pyramid shows the total dry mass of all living organisms at each trophic level.
Explanation:
Because the amount of the pollutant increases as it goes up the food chain, the biomagnification pyramid is inverted whereas the energy pyramid is consistently upright.
What is biomagnification?Biomagnification is the amassing of a chemical by an organism as a result of exposure to both food and water, resulting in a concentration that is higher than what would have been expected from equilibrium and higher than what would have occurred with only water exposure.
When dangerous chemicals like DDT that remain in the environment are indirectly absorbed by living things through food, this process is known as biomagnification.
When a higher-order organism consumes a lower-order organism that contains such compounds, the chemicals may accumulate in the higher-order organism.
The biomagnification pyramid is upside down because the amount of the pollutant increases as it moves up the food chain. The energy pyramid, however, is always upright.
Thus, this can be the comparison between the energy pyramid and biomagnification.

Determine which situation could NOT be an example of interspecific competition.
A. Two organisms competing for food.
B. Two organisms competing for a mate.
C. Two organisms competing for water.
D. Two organisms competing over territory.
Answer: it would be D
Explanation:
The situation that could not be an example of interspecific competition is two organisms competing for a mate. Thus, the correct option is B.
What is an Interspecific competition?Interspecific competition may be defined as an instance of competition between individuals of different species.
The situation of two organisms competing for a mate illustrates an example of intraspecific competition. This is because the two individuals mate with a member of their own species in order to produce fertile offspring.
The individuals of different species do not undergo interspecific competition.
Therefore, the correct option for this question is B.

Ozone in the stratosphere is a toxic pollutant that can cause tightness or shortness of breath.
True
False
Ozone in the stratosphere is a toxic pollutant that can cause tightness or shortness of breath is a true statement.
What is ozone layer?One layer of the stratosphere, the second layer of the Earth's atmosphere, is the ozone layer. The layer of insulating gases that clings to our planet is known as the stratosphere.
A small layer of the Earth's atmosphere called the ozone layer absorbs nearly all of the sun's harmful UV energy. Areas of the ozone layer degradation are frequently referred to as "ozone holes." That is incorrect. Damage to the ozone layer is more akin to a very thin patch than a hole.
Therefore, Ozone in the stratosphere is a toxic pollutant that can cause tightness or shortness of breath is a true statement.

In your own words, explain how a single molecule of glucose is converted into ~30 or more molecules of ATP in cellular respiration
Answer: Throughout the stages of cellular respiration
Explanation:
Fair warning I'm only a college freshman so you may be able to find more detailed answers than what I'm about to give you.
During cellular respiration there are a number of processes that must be taken into account when dealing with a glucose molecule.
Glycolysis: The molecule of glucose is a 6-carbon molecule, in this process that takes place in the cytoplasm of the cell, it is split into two 3-carbon molecules, these are pyruvates, during this, 2 ATP is made as a byproduct(along with 2 NADH molecules but I'll just focus on the ATP moving forward).
Transformation of pyruvate: For eukaryotic cells, the pyruvate molecules from Glycolysis are transferred into the mitochondria, which of course are sites for cellular respiration. With Oxygen available, aerobic respiration would continue but if not, fermentation would take place which would drastically reduce total ATP reduction throughout one cycle. The pyruvates are transformed into a 2-carbon acetyl group which is then oxidized and now compatible for Coenzyme A to pick up, which results in the compound Acetyl Coenzyme A. This process ends up producing 1 NADH molecule from the reduction of NAD+ due to the 2 carbon molecule being oxidized.
Citric Acid Cycle: This stage begins as soon as Acetyl CoA combines with a 4-carbon molecule called Oxaloacetate which ends up forming citric acid, that has 6-carbon atoms. Long story short the citric acid goes through a great number of reactions that produces a total of 2 ATP molecules.
Oxidative Phosphorylation: This stage of aerobic respiration consists of the electron transport chain and chemiosmosis process. The energy of NADH and FADH2 molecules that were produced in the Citric Acid Cycle is what's used to create the final majority of ATP molecules within this whole process. 1. Throughout the electron transport chain, excited electrons move along its network in the inner membrane of the mitochondria. As it moves, molecules it passes by uses the electrons energy to pump Hydrogen ions/protons from the inner membrane towards the intermembrane space. This transfer of ions creates an electrochemical gradient which is necessary for the synthesis of ATP in the following process, Chemiosmosis. The Electron Transport Chain produces about 2-3 ATP. 2. In Chemiosmosis, the newly formed electrochemical gradient causes the gathered Hydrogen ions to flow from the intermembrane space into the matrix, therefore lowering the its concentration(search up a image of this if you need to). This flow is thanks to and mediated by ATP synthase. Finally ATP synthase accepts 3-4 Hydrogen ions so an inorganic phosphate group can react with an ADP (Adenosine diphosphate) compound to produce one ATP molecule. In total, 24-28 molecules of ATP is formed.
This is how a single molecule of glucose can produce more than 30 molecules of ATP in aerobic cellular respiration. Fermentation on the other hand, would most likely produce half of which aerobic respiration would produce.
What condition occurs when epidermal cells are created too quickly? a. Acne c. Psoriasis b. Skin cancer d. Chicken pox.
The condition that occurs when epidermal cells are created too quickly is known as psoriasis. In this disease, the cell cycle of skin cells is abnormally accelerated.
Psoriasis is a skin disease associated with itchy patches of thick, red skin, especially in the knees, trunk, and scalp.
Psoriasis is an autoimmune disease caused when the immune system attacks healthy skin cells.
Psoriasis is well characterized by hyperproliferative keratinocytes, which are the most prominent type of cell within the epidermis.

inverse relationship to population growth.
es )
A)
deforestation
B)
violent political conflict
spread of communicable diseases
D)
biodiversity of plant and animal species
Answer:
D
Explanation:
As population grows all the above factors increase expect the biodiversity of animal and plant species.
On a basic level, it is obvious that population increase and per capita income growth are related. Per capita income is simply total income divided by the population. Thus, option D is correct.
What inverse relationship to population growth?When attempting to forecast changes in population size, demographers frequently focus on four essential criteria.
The population's starting age profile (whether it is relatively young or old to begin with), migration, and fertility rates (death rates; life expectancy).
Depending on particular environmental factors, two different patterns of population expansion may manifest: In a perfect, limitless environment, an exponential growth pattern (J curve) manifests itself.
The development of a logistic growth pattern (S curve) occurs when external forces reduce the pace of growth.
Therefore, The gap between the growth rates of income and population is roughly equivalent to the growth rate of per capita income.
