The function of most proteins depends primarily on the?
Answers
The function of most proteins depends primarily on the Tertiary structure which formed by peptide bond, hydrogen bond, covalent bond, and disulphide bond.
Protein Structure- The three-dimensional configuration of an amino acid-chain molecule's atoms is known as protein structure. Segments of amino acids, the polymer's monomers, are used to create proteins, specifically polypeptides. A single amino monomer can also be referred to as a residue, which denotes a polymer's repeating unit.
Peptide Bond- Whenever the carboxyl group with one molecule combines with amino amino group of another molecule, the outcome is the production of an amide group and a water molecule, which is known as a peptide bond.

What is theory in science means
Answers
Solution:
Scientists use conceptual processes to understand nature through questions or propositions.
The method on which scientific investigations are based is the scientific method and it is the hypothesis-prediction approach.
This approach allows scientists to modify their conclusions as new information becomes available.
The method consists of five steps:
1. Make observations
2. Ask questions
3. Form hypotheses, which are tentative answers to questions.
questions
4. Make predictions based on the hypotheses
5. Test the predictions by making additional observations or conducting experiments.
If the test results support the hypothesis, it is subjected to additional predictions and tests. If they continue to support it, confidence in its correctness increases and the hypothesis comes to be considered a theory.
Therefore, a theory is a demonstrable model supported by experimentation (empirical facts) and data that explains a phenomenon. In other words, a theory is a set of concepts, including abstractions of observable phenomena and quantifiable properties, along with rules that express the relationships between observations of those concepts.

1. Correct the following paragraph describing pigments, energy and photons.
Photons are the particle that makes up light. Photons with a longer wavelength of light have more energy than photons with a shorter wavelength. Pigments can only absorb photons that have the exact amount of energy required to move
an electron to a higher energy state. If a photon's energy doesn't match exactly, the photon is absorbed. Most plants
have one kind of pigment in their leaves. If a pigment is red, it absorbs only photons with a red wavelength.
2. Correct the following describing the light dependent reactions of photosynthesis.
The first photosystem is photosystem II. In this photosystem, photons are absorbed by pigments in the antenna complex and the energy is used to create an electron at the reaction center. This excited electron is then given to ADP.
The electron carrier is then reduced which provides energy for the electron transport chain to pump H+ ions into the chloroplast stroma. Then, H+ flows through ATP synthase to power the reaction of ATP - ADP + P. The electron that
left the reaction center is replaced through condensation of a water molecule into oxygen and nitrogen. The second photosystem is photosystem I. In this photosystem, photons are absorbed by pigments in the antenna complex and the energy is used to re-excite the low-energy electron from photosystem II at the reaction center. This excited electron is then used to oxidize NADP+ into NADPH.
Answers
1. Light has two personalities. Light acts primarily as a wave, but it may also be thought of as a collection of tiny bundles of energy known as photons. If a pigment is red, it absorbs photons of different wavelengths while reflecting photons of the same wavelength.
2. Photosystems, which are huge complexes of proteins and pigments (light-absorbing molecules) that are tuned for light harvesting, play an important part in light reactions. Photosystems are classified into two types: photosystem I (PSI) and photosystem II (PSII).
How to illustrate the information?1 A photon is an electromagnetic energy packet. It is the fundamental unit of all light. The photon is also known as a "quantum" of electromagnetic energy. A photon's energy is proportional to its wavelength: longer wavelength photons have less energy, while shorter wavelength photons have more.
2 Light energy is used in light-dependent reactions to create two molecules required for the next step of photosynthesis: the energy store molecule ATP and the reduced electron transporter NADPH. Light reactions occur in the thylakoid membranes of chloroplast organelles in plants.

What happens when a change in the DNA of an egg or sperm is not repair will depend on the location of the mutation. This means that whether the changed DNA region is a gene, a regulating sequence or "junk" DNA, the cell can survive or not. In case it survives, the replaced nucleotide may not altere the protein it codifies, resulting in a silent mutation, or it can cause altereations in the functioning even though not being lethal.

Which is the best definition of activation energy?
A) the energy required to end a chemical reaction
B) the energy required to bind a substrate to an active site
C) the energy required to form or break the bonds of reactant molecules
D) the energy required to re-form bonds in product molecules
Answers
Activation energy is the energy required to form or break the bonds of reactant molecules (option C).
What is activation energy?Activation energy of a chemical reaction is the energy required to initiate a reaction.
For example, the flame from the fuse of a firecracker provides a small initial amount of energy, after which the explosive reaction proceeds by itself, releasing a considerably larger quantity of energy.
The activation energy of a chemical reaction is strictly required to make a reaction occur i.e. conversion of reactants to products.
Therefore, the energy needed to break the chemical bonds of a reactant molecule is the activation energy.

A population's genetic makeup evolves throughout time as a result of the process of evolution. Adaptations made by organisms to their altering surroundings are reflected in evolution, which can lead to changed genes, unique features, and the emergence of new species. Both increases in genetic diversity and shifts in allele frequencies throughout time affect evolutionary processes. Experimentally, the evolutionary process from a "Big Bang" genesis to the protocell and from the advent of the protocell and a diversity of species to Darwin's mental capacity (mind) and society is being reexamined (The Descent of Man). The focus on endogenous ordering is one of studies' most fundamentally revisionary effects.

Mitosis is the department of frame cells and meiosis is the division of the sex cells or gametes-producing cells.
Mitosis is a process wherein a single cell divides into identical daughter cells. Whereas Meiosis is a technique in which a single cell divides twice to produce 4 cells containing 1/2 the initial quantity of genetic materials.
Meiosis I, the primary meiotic division, begins with prophase I. For the duration of prophase I, the complex of DNA and protein referred to as chromatin condenses to shape chromosomes. The pairs of replicated chromosomes are known as sister chromatids, and they remain joined at the center known as the centromere.

Some animals such as corals and sponges are sessile. These animals don't expend their energy to catch their prey they live by attaching to a substrate. They choose a suitable spot to feed. They can be found on tree trunks, on rocks, and even in water.
Plants are typical example of sessile organism. They permanently grow in one spot taking nutrients from the soil and making use of the available sun for photosynthesis. Sessile organism doesn't have the ability to move from one place to another and it has a big advantage as they save energy and they also develop unique feeding mechanisms enabling them to survive in their habitat.

Kudzu kills native plants by smothering them and blocking their sunlight. Climbing vines can girdle trees, and their weight can uproot trees. Loss of trees and plants to kudzu threatens agricultural and timber production. Kudzu would destroy the native species. Few plants can survive once smothered by kudzu and small ecosystems can be radically altered. Infestations quickly spread in open habitats, rapidly covering the soil and low growing vegetation, and only slowed by adjoining forests. Kudzu can affect indigenous plants and completely modify the structure of the ecosystem.
Kudzu is widely believed to drastically reduce biodiversity because of its ability to smother other vegetation and develop large-scale monocultures. It can climb overtop and subsequently kill new seedlings or mature trees. Forestry problems associated with aggressive vines such as kudzu include mortality of edge trees, exclusion of native plant species, and potential to increase fire hazard during winter.
