Answer:

An organism requires all four main biomolecules because each provides a specific and necessary function for the organism. None of the biomolecules is more important than another, and if any of them were missing, life would not be possible.

Explanation:

The main biomolecules of living beings are carbohydrates, proteins, lipids and nucleic acids, each with a specific function and necessary for the development of life.

The presence of these four biomolecules is necessary because each one fulfills specific and irreplaceable functions, such as:

If one of the main biomolecules were missing, the function it provides could not be supplied by another, which would imply the non-viability of a living being. If carbohydrates are missing there is no source of energy, without proteins there would be no tissues like muscle and no enzymes to facilitate organic reactions and without lipids there would be no cells. The absence of nucleic acids, per se, would determine the impossibility of all organic processes.

No one biomolecule is more important than another. Each one of them fulfills a specific and necessary function that cannot be supplied by another biomolecule.

All organic molecules are necessary, fulfilling an important function. The lack of any biomolecule in the organism is incompatible with life.

An organism requires all four of the main biomolecules because they're all important for the effective functioning of the organism.

It should be noted that the main biomolecules include protein, lipid, carbohydrates, and nucleic acids. They all play a vital role in how an organism functions.

If any of these biomolecules were missing, the function that can be provided by the biomolecule can't be provided by another biomolecule since they all play different roles. Also, there's no biomolecule that's important than another.

Thank You!!

Explanation:

Answer:

Proteins

Explanation:

There are proteins in the membrane that have channels for large polar molecules to move into or out of the cell since the plasma membrane is made of a phospholipid bilayer where the inside is non polar. This means large polar molecules need help from proteins to cross the plasma membrane.

Answer:

Photosynthesis is the process that removes carbon dioxide from the Earth's atmosphere.

Explanation:

One way CO2 is naturally removed from the atmosphere is photosynthesis. Details about photosynthesis is given below.

Photosynthesis is the process by which green plants obtain their nutrition using sunlight as an energy source.

Photosynthesis combines carbon dioxide and water in the chloroplast of plant cells to synthesize glucose molecules.

The atmospheric carbon dioxide gets into the plant via the stomata on the leaves.

Therefore, One way CO2 is naturally removed from the atmosphere is photosynthesis.

Answer:

A mutation is the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes. Mutations in sex cells are more serious because they are heritable and affect the next generation.

Explanation:

Answer:

Lipids cannot be considered polymers because, unlike carbohydrates, they are constituted of several units that are different.

Explanation:

Unlike other biomolecules —such as carbohydrates, proteins and nucleic acids— lipids are not considered polymers because the subunits that form them are different, in addition to being made up of a larger molecule, from which they can grow.

Polymers are formed by repeating subunits, having the possibility of forming and growing at either end of their chain. Polymerization is a characteristic shared by carbohydrates, proteins and nucleic acids, but not by lipids.

Lipids are biomolecules of hydrophobic nature formed predominantly by carbon and hydrogen, whose structure can be linear or forming rings. They have biological importance as they are the main component of cell membranes, reserve energy substrate and form molecules such as hormones.

General Formulas and Concepts:

Chemistry - Atomic Structure

Explanation:

Step 1: Define

17.13 g MgO

Step 2: Identify Conversions

Molar Mass of Mg - 24.31 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of MgO - 24.31 + 16.00 = 40.31 g/mol

Step 3: Convert

[tex]17.13 \ g \ MgO(\frac{1 \ mol \ MgO}{40.31 \ g \ MgO} )[/tex] = 0.424957 mol MgO

The correct answer among the given statements is option A. An E.coli cell divides into two new cells, according to the cell theory.

Theodor Schwann introduced the traditional cell hypothesis/cell theory in 1839. This theory has three components. Cells make up all living things, according to the first section. Cells are the essential building blocks of life, according to the second section. The third section states that cells are descended from earlier, already existent cells that have proliferated. One of the fundamental ideas in biology is the concept of the cell/cell theory. A suggested and commonly recognized hypothesis of how the majority life on Earth operates is called the cell theory. There are following tenets of the Cell hypothesis.

1) Cells make up all living things.

2) Other living cells make all of the current cells.

Regenerative medicine has focused on growing specialized tissues for spinal cord injuries, diabetes, cancer, multiple sclerosis, Parkinson’s disease, and many other currently un thought-of applications.

Regenerative medicine has been defined as the branch of translational research in tissue engineering and molecular biology that deals with replacing, engineering or replace human or animal cells, tissues or organs to restore normal functioning. It also develops method to regrow, repair or replace damaged or diseased cells, organs or tissues.

Therefore, mRNA sequence is mutated from CCC GGG to CCG GGG as it is the point mutation and silent mutation and the third cytosine is mutated to guanine => point mutation CCC codes for proline and so does CCG it has been observed in the medicines too.

eukaryotic: organisms whose cells contain a nucleus and other membrane-bound organelles

animals, plants, fungi, and protists, as well as most algae

single cell or multicellular

eukaryotic cells have a distinct nucleus containing the cell's genetic material, while prokaryotic cells don't have a nucleus and have free-floating genetic material instead

Explanation:

Answer:

Prokaryotic cells lack a nucleus and are usually bacterial while eukaryotic cells have a nucleus, and chromosomes. On the other hand, prokaryotes have chromosomes but they are different, so they do not classify as chromosomes.

Answer:

D. Molecules called pumps function to control active transport.

Explanation:

Active transport is one of the two types of transport (the other being passive transport). It is the type of transport in which substances move against their concentration gradient i.e. from a lower concentration to a higher concentration. Hence, due to this, energy input in form of ATP is required by the cell.

However, the process of active transport makes use of certain molecules called PUMPS to control it. The pumps moves ions/molecules against their concentration gradient. An example is the sodium-pottasium pump which moves sodium ions from a region of low conc. to a region of high conc.

When an enzyme binds to its substrate, an enzyme-substrate complex is formed. The activation energy of the reaction is reduced, and the reaction proceeds more rapidly thanks to the complex's provision of certain ions or chemical groups that actually form covalent bonds with molecules at a vital point of the reaction process.
