Hydrogen and Oxygen will have completely new after they bond to become water.

A molecule of water has two hydrogen atoms. Both of these atoms can form a hydrogen bond with oxygen atoms of different water molecules.

Water molecules are polar, so they form hydrogen bonds. This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density.

The lactose broth fermentation tubes already contain a pH indicator that changes from red to yellow to indicate lactose fermentation by coliform bacteria.

A pH indicator is not needed in lactose broth fermentation tubes when testing for the presence of coliforms because the lactose broth already contains a pH indicator that changes color to indicate lactose fermentation. After inoculation and incubation, the observation of a color change from red to yellow in the media signals coliform growth due to the breakdown of lactose, which produces acidic byproducts, lowering the pH. This visual cue is a straightforward method to assess the potential fecal contamination of water samples by coliform bacteria, such as E. coli.

The largest and most diverse group of seedless vascular plants are ferns, with around 12,000 different species. Other seedless vascular plants include club mosses, horsetails, and whisk ferns. Non-vascular seedless plants, such as liverworts, mosses, and hornworts, are generally smaller and absorb water and nutrients through all their exposed surfaces.

The largest and most diverse group of seedless vascular plants are ferns. There are about 12,000 species of ferns that inhabit a variety of environments, from the tropics to temperate forests. However, most ferns prefer moist and shaded places. Apart from ferns, other seedless vascular plants include club mosses, horsetails, and whisk ferns. Unlike seed plants, these species still require water for fertilization.

Another group of seedless plants are the nonvascular plants, which include liverworts, mosses, and hornworts, collectively known as the bryophytes. These plants are generally small and absorb water and nutrients through all their exposed surfaces.

Vascular plants, which encompass more than 90 percent of Earth's vegetation, developed a network of specialized cells that conduct water and solutes. These evolutionary innovations allowed them to spread to all habitats. However, not all vascular plants are seed plants; the earliest vascular plants, like lycophytes (club mosses) and pterophytes (ferns, horsetails, and whisk ferns), are seedless.

In enzyme-controlled reactions, a substrate is the reactant or the molecule upon which the enzyme acts. They interact at the enzyme's active site and undergo dynamic changes to facilitate the chemical reaction. Each enzyme is designed to work with a specific substrate.

In an enzyme-controlled reaction, a substrate is essentially the reactant, or the molecule upon which the enzyme acts. The enzyme binds to the substrate at a specific location known as the active site. This binding is facilitated by the unique combination of amino acid side chains within the active site, perfectly suited to bind to one specific chemical substrate (or substrates). Enzymes display specificity because only a substrate with a particular shape and electrical charge can bind to the corresponding active site.

Moreover, enzymes and substrates undergo dynamic changes to induce the transition state of the substrate - a high-energy, unstable state occurring during a chemical reaction. This process known as induced fit, resembles a hand fitting into a glove, where the glove represents the enzyme and the hand represents the substrate.

Therefore, we say that each enzyme is specifically matched for each substrate and hence each chemical reaction. Some enzymes, however, can act on several different but structurally related substrates.

A substrate in an enzyme-controlled reaction is the molecule that the enzyme acts upon. It binds to the enzyme's active site, undergoes a chemical reaction, and is converted into a product. Substrates are crucial for the specificity and the catalytic process of enzymes.

In an enzyme-controlled reaction, a substrate is the molecule that binds to the enzyme's active site. The enzyme catalyzes a chemical reaction, transforming the substrate into a different molecule, known as the product. This process often involves the formation of an enzyme-substrate complex, indicated by the equation E+S
ightarrow ES
ightarrow E+P, where E represents the enzyme, S is the substrate, and P is the product.

Enzymes are highly specific to their substrates due to the unique fit between the substrate and the enzyme's active site, a concept sometimes referred to as the "lock and key" model. However, the induced fit model explains that the active site of the enzyme changes shape upon substrate binding, which facilitates the catalytic process. Substrates play a critical role in biochemical reactions and are not altered or consumed by the reaction, allowing enzymes to be reused multiple times.

To remedy overly acidic soil, a gardener can add lime which reacts with hydrogen ions in the soil to form water and carbonate ions. This neutralizes the acidity of the soil, making it more suitable for plant growth. Contributing to soil acidity is the phenomenon of acid rain, caused by human activities like burning of fossil fuels.

To remedy soil that is overly acidic, a gardener can add a substance, such as lime (calcium carbonate, CaCO3) to the soil. When lime is added to acidic soil, it reacts with the hydrogen ions present in the soil to form water and carbonate ions. This reaction can be represented as:

CaCO3 + 2H+ -> Ca2+ + H2O + CO2

The carbonate ions (CO2) evaporate into the atmosphere as carbon dioxide gas. This chemical reaction neutralizes the acidity of the soil (raises the pH), making it more hospitable for plant growth. In addition, certain human activities can affect the pH of soil, such as the burning of fossil fuels, which releases sulfur dioxide into the atmosphere. This can result in acid rain (rainwater combined with sulfur dioxide forms weak sulfuric acid), which can lower the pH of soil, making it overly acidic.

To remedy soil that is overly acidic, a gardener can use various methods to raise the pH level and make the soil more neutral. One common method is to add lime, such as agricultural lime or dolomitic lime, to the soil. When lime is added to acidic soil, it reacts with the H+ ions in the soil to form water, thus decreasing the acidity. The chemical reaction involved can be represented as:

CaCO3 + 2H+ → Ca2+ + H2O + CO2

Another method is to add organic matter, such as compost or manure, to the soil. The organic matter contains alkaline compounds that can help neutralize the acidity. For example, the reaction between organic matter and acid in the soil can be represented as:

Organic matter + H+ → H2O + CO2

Answer: FALSE ON EDGE 2021

Explanation:

Answer: Option (c) is the correct answer.

Explanation:

A compound that consists of only carbon and hydrogen atoms is known as a hydrocarbon.

For example, [tex]C_{5}H_{12}[/tex] is a hydrocarbon and its name is pentane.

A hydrocarbon can have single, double or triple bonds. A hydrocarbon with double bonds is known as an alkene and a hydrocarbon with a triple bond is known as an alkyne.

A hydrocarbon does not have or contain an oxygen atom.

Hence, we can conclude that the statement no, a hydrocarbon contains only carbon and hydrogen atoms, is correct.

Answer:

C.virus cannot reproduce outside a host cell and are therefore nonliving

Explanation:

I believe the only reason why they could have survived successfully despite living only on the same tree and they are large in number is because:

“They feed on different parts of the same trees.”

So this means that although they are many of them feeding on the tree, there is no food deficiency occurring since they are getting their source of food from different parts of the tree anyway.
