There are twenty types of amino acids are there in our body for protein synthesis.

As we all know that our body needs various types of amino acids for protein synthesis, but it doesn't work due to the presence of amino acids only, but there are also many similar biomechanical reactions needed for the smoothening process of body functioning.

Now it is clear about the presence of amino acids. Now, it is necessary to understand what are the functions of amino acids in our body, amino acids help to synthesize proteins they also help in repairing the dead cells into new cells and much more.

Hence at last we can say that amino acids plays a vital role in the synthesis of protein, as protein are the building blocks of our body.

Do Eukaryotic Cells have Mitochondria?

In addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and lysosomes.

What is a  Eukaryotic cell?

A eukaryotic cell is one of two different types of cells. Organisms that are based on the eukaryotic cell are called “eukaryotes” and include plants, animals, fungi, and protists.

What is Mitochondria?

The mitochondrion (plural mitochondria) is a membrane-bound organelle found in the cytoplasm of eukaryotic cells. It is the power house of the cell; it is responsible for cellular respiration and production of (most) ATP in the cell. Each cell can have from one to thousands of mitochondria. Mitochondria also contain extranuclear DNA that encodes a number of rRNAs, tRNAs, and proteins.

One part of a person's carbon footprint, which is a measure of our impact on the environment, is the amount of carbon dioxide released by processes that make products they consume because this is closely related to the harm we cause to the planet. For example, the carbon footprint of fabricating plastic recipients is not the same carbon footprint if we use wood recipients.

Let's imagine that in the first case, to produce this kind of product, first it should be extracted petrol from carbon sinks, which high probabilities could be spoiled in water bodies, harming the water and the organisms that depend on it. If, on the other hand, we use products from renewable resources, like wood, our carbon footprint would be smaller.

The answer to this question should be the second one then: B. released by processes that make products he or she consumes.

Answer:

Due to difference in concentration.

Explanation:

The concentration of Urea in blood is higher as compared to concentration of urea in dialysis so the urea from the blood moves from the blood towards dialysis due to concentration gradient. The dialysis fluid contains no concentration of urea, so all of the urea diffuses from the blood into the dialysis fluid due to the high concentration in the blood to the lower concentration in the dialysis fluid. So we can say that diffusion of urea occur due to concentration gradient.

Explanation:

One resource used for energy production that can impact the natural resource of ozone layer depletion is coal. Burning coal releases pollutants like sulfur dioxide, nitrogen oxides, and mercury into the atmosphere, which can contribute to the formation of smog and acid rain. These pollutants can also react with other chemicals in the atmosphere to break down ozone molecules, contributing to the depletion of the ozone layer. So, the way humans use coal as an energy resource can have a negative impact on the ozone layer and the environment.

Enzymes speed up the chemical reactions (3) by lowering the activation energy of a  reaction.

Enzymes are the biological catalysts that enhance the rate of chemical reactions inside the living organisms. These enzymes are very essential to make the body function normally. The various examples of enzymes present inside the human body are: pepsin, amylase, catalase, etc.

Activation energy is the minimum amount of energy required to begin a chemical reaction. More is the activation energy more is the time required to complete the chemical reaction. This is the reason why enzymes are required to speed up the chemical reactions.

The type of cell transport illustrated is facilitated diffusion.

A facilitated diffusion is a form of diffusion that requires the assistance of special molecules.

Facilitated diffusion differs from ordinary/spontaneous diffusion. In the latter, molecules move from the region of their higher concentrations to the regions of their lower concentrations.

In facilitated diffusion, molecules also move from their region of higher to their region of lower concentrations. However, they require the assistance of carrier molecules. For example, carrier proteins.

In the illustration, the molecules of sugar diffused using the assistance of proteins embedded in the membrane. This is a good example of facilitated diffusion.

Explanation:

The Bohr Model of the Atom is a useful model for understanding the behavior of atoms, but it has limitations in accurately describing the behavior of real-world atoms.

The Bohr Model assumes that electrons orbit the nucleus in circular paths at specific energy levels, which is not entirely accurate. In reality, electrons move in a probabilistic cloud-like formation around the nucleus, and their exact position and energy can only be described in terms of probabilities.

Additionally, the Bohr Model does not account for the effects of electron-electron interactions, which become more significant as the number of electrons in an atom increases. Therefore, while the Bohr Model is still a valuable tool for explaining atomic behavior, it is not entirely accurate and should be used in conjunction with other models, such as the quantum mechanical model of the atom.

In the case of oxygen, the Bohr Model can provide a basic understanding of the number of electrons, their distribution in energy levels, and the overall behavior of the atom. However, to fully understand the properties and behavior of oxygen, one must take into account the complexities of the electron cloud and electron-electron interactions, which are better described by the quantum mechanical model.

The nervous system helps all the parts of the body to communicate with each other. It also reacts to changes both outside and inside the body. The nervous system uses both electrical and chemical means to send and receive messages.

Secondary succession is the kind of succession that might develop in a neighborhood park after the Zombie Apocalypse if the grass wasn't cut anymore and pioneer species would first colonize the bare soil.

Thus, pioneer species like weeds and grasses would colonize the bare soil and disturbed regions in the initial stage of secondary succession. These species can swiftly adapt to a new habitat since they are frequently resilient and rapidly developing.

In secondary succession, the pioneer species are the early settlers multiply and spread, the soil conditions become more stable and draw in additional species like shrubs and tiny trees. These animals are modifying the environment in a way that makes it possible for bigger and more diversified populations of creatures to live in more complicated settings.

Mendel chose the pea, one of many species, to study because the plants and seeds exhibit a variety of distinctive characteristics that appear in two readily recognizable forms (e.g., seed shape is round or wrinkled; plant height is tall or short).

George Mendel, the father of genetics, chose pea plants for his genetic experiments for a variety of reasons, including

• Garden plants are simple to grow.

• Pea plant blooms are hermaphrodites, which means they exhibit traits of both sexes.

• Plants of the pure breed can be easily obtained through self-fertilization.

• Pea plants produce more quickly than other plants.

• They have a high rate of survival and remarkable disease resistance.

Gregor Mendel's research on pea plants led him to the fundamental ideas of inheritance. He came to the idea that genes are passed down from each parent as unique, paired units.

Mendel observed how parental genes separated and if they showed up as dominant or recessive qualities in the offspring. Gregor Mendel experimented with hybridization on about 29,000 pea plants. Mendel found that peas were the perfect subject since they possessed seven easily observable features that he could control. He set up two settings before starting his pea studies.

As a result, we can infer that Mendel chose the pea as the species to study out of all the others since it has a diversity of distinguishing traits in both its plants and seeds.
