If you remove the herbivores from a food web that also includes grass, mushrooms, lizards, and hawks, the organisms that would be affect are lizards, and hawks.
A food web shows all the possible feeding relationships in an ecosystem. Recall that there is an interconnection between organisms which involves exchange of matter and energy through feeding relationships.
In the food web, the grass is the producer, the herbivores are the primary consumers and the carnivores are the secondary consumers. These secondary consumers eat the primary consumers.
Lizards eat grasshoppers and hawks eat birds. When these are removed from the food web, the Lizard and Hawk are most affected because they will starve owing to lack of prey.

Explanation:
Identify the independent variable and the dependent variable in your penny
experiment?
Answer:
Independent Variable = The thing you change
Dependent Variable = The thing you measure
Explanation:
An independent variable is the thing that you are changing in your experiment to be able to get different results. For example, if a question says "What will happen to a cup of tea when you change the temperature of the water added to it?"... then the independent variable will be the temperature of the water.
A dependent variable is the thing that you are measuring. For example, if you are studying the amount of light absorbed from different surfaces, then the dependent variable is the unit of light absorbed, which would be measured in Au (Absorbance unit).
You can now take this knowledge and apply it to your question.

coevolution
mimicry
environmental resistance
commensalism
ecological succession
The newts have become more poisonous over time, as a result, leading to a kind of evolutionary arms race. This is an example of coevolution.
Coevolution is the process of evolutionary change that occurs between pairs or group of species as they interact with one another.
The predator-prey relationship is the most common type of coevolution. This involves the prey evolving so as to avoid capture and thus leading to the evolution of the predator so as to become more effective hunters.

mark as brainliest plz? :)
A liquid turning into a gas is evaporation. It is how water gets from the surface of the Earth to the atmosphere.
Temperature, surface area, wind speed, and humidity affect a liquid's evaporation rate.
Latent heat is a form of energy held in the evaporated water when it evaporates and cools.
Most of the air's moisture evaporates from rivers, lakes, seas, and oceans. Water at the surface of the Earth evaporates into water vapor, which rises into the sky and forms clouds, which eventually release water back onto Earth as precipitation.

Lactic acid fermentation can be modeled by which equation?
O Lactic acid + NADH → Pyruvic acid NADH
O Pyruvic acid + NAD+ → Lactic acid + NADH
O Lactic acid + NADH → Pyruvic acid + NAD+
O Pyruvic acid + NADH → Lactic acid + NAD+
Lactic acid fermentation can be modeled by the following equation: Pyruvic acid + NADH → Lactic acid + NAD+
LACTIC ACID FERMENTATION:
Fermentation is a process undergone by some anaerobic organisms. Ideally, the process of cellular respiration proceeds as follows in the presence of oxygen: Glycolysis- Kreb cycle - ETC. However, in the absence of oxygen (anaerobic condition), the product of glycolysis which is pyruvic acid combines with an electron carrier (NADH) to give rise to lactic acid and NAD+. This means that pyruvic acid is reduced while NADH is oxidized as modelled in the following equation:Pyruvic acid + NADH → Lactic acid + NAD+Learn more at: https://brainly.com/question/11502989?referrer=searchResults
Answer to Question 1:
Well, given the choices to the question above 'Lactic acid fermentation can be modeled by which equation?', I would say that the best choice would be 'Pyruvic acid + NADH → Lactic acid + NAD+', or in other words, Option D.
Explanation for Question 1:
For a further explanation expanding more on the first question and showing why, the user above's answer is super helpful.
Answer to Question 2:
For the additional question asked 'In the Krebs cycle, how is citric acid formed?', I didn't see the options, however I believe they are:
O Carbon dioxide bonds with a chain of coenzyme A.
O Pyruvic acid molecules are broken down by an acetyl group.
O Acetyl-CoA joins with a large molecule called ozaloacetic acid.
O Enzymes combine hydrogen ions, oxygen, and electrons.
^ This being said, I would say your best choice would be Option C.
Explanation for Question 2:
The Krebs cycle begins when acetyl-CoA combines with a four-carbon molecule called OAA, aka oxaloacetate. This begins to produce citric acid, in which has six carbon-atoms. This is why the Krebs cycle is also referred to as 'the citric acid cycle.'

select the cell cycle impairments that you predict would lead to cancer. recall that cancer arises from unregulated, repeated cell divisions. choose all that apply.
Cancer cells can arise in a variety of ways, the most common, however, tends to be genetic mutations.
Genetic mutations can occur during the life of a cell due to outside factors such as:
The food we eatThe environment we expose the cell toThe substances that touch the cell (e.g skin cells)That being said, the most common time for a genetic mutation to take place is during cellular division. During this time the DNA that encodes the cells is duplicated. Genetic mutations in this DNA sometimes cause the elimination of programmed cell death.
Programmed cell death is what tells a cell when it should stop growing and dividing. This is a regulatory function designed to keep the number of cells at a balance, growing only when needed. As this cell multiplies, this produces an increasing number of cells that will not die. The accumulation of these cells is referred to as cancer.

The sequence of nucleotides defines the primary structure of DNA and RNA where the nucleotides are linked to the oxygen on the 5' carbon of one through the phosphodiester bond linking to the oxygen on the 3' carbon of the other.
What is DNA?Deoxyribonucleic acid is a polymer which is made up of two polynucleotide chains that coil around each other to carry the genetic instructions for growth, function, development, and reproduction in all known organisms and many viruses. DNA and RNA are nucleic acids.
DNA is made up of chemical building blocks called nucleotides which are building blocks made up of three parts:
1. A phosphate group
2. A sugar group
3. One of four types of nitrogenous bases i.e. adenine (A), cytosine (C), guanine (G), and thymine (T)
To form a strand of DNA, nucleotides are linked in chains, alternating between phosphate and sugar groups.
Thus, the sequence of nucleotides defines the primary structure of DNA and RNA where the nucleotides are linked to the oxygen on the 5' carbon of one through the phosphodiester bond linking to the oxygen on the 3' carbon of the other.
