What is the chemical reaction of photosynthesis?

The chemical reaction of photosynthesis is given as follows;

6CO₂(g) + 6H₂O(l) + Energy from light → C₆H₁₂O₆(s) + 6O₂(g)

Six molecules of gaseous carbon dioxide (CO₂) combine with six molecules of liquid water (H₂O) in the presence of energy from Sunlight  to produce  one molecule of solid glucose (C₆H₁₂O₆) and six molecules of gaseous oxygen (O₂)

Thus, option "B" is correct.

Which biomolecule provides the instructions to build enzymes?
A. Carbohydrates

B. Lipids

C. Nucleic acids

D. Proteins

Answers

The correct answer is D. Proteins

Enzymes are biological molecules (proteins) that act as catalysts and help complex reactions occur everywhere in life.

Hope this helps :D

Proteins are the building blocks of enzymes, and proteins are made up of amino acids that are linked together in one or more polypeptide chains. Therefore, option (D) is correct.

What are enzymes?

Enzymes are proteins that aid in the acceleration of metabolic processes, also known as the chemical reactions that take place in our bodies. They are responsible for the creation of some chemicals while also decomposing others. Enzymes are present in everything that is alive. Enzymes are something that are produced by our bodies spontaneously.

Enzymes regulate most biochemical reactions in animals, plants, and microbes, thus there are many examples. Animal digestive enzymes are well-known. Gastric juices break down food with the enzyme pepsin. Salivary amylase turns starch into sugar, starting digestion.

Stars form from what celestial objects ?

Answers

  Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example, a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. Stars begin their lives as clouds of dust and gas called nebulae. The gravity of a passing star or the shock wave from a nearby supernova may cause the nebula to contract. Matter in the gas cloud will begin to coalesce into a dense region called a protostar.

ONLY 9

Answers

Answer:

c. metallic bond

Explanation:

Metallic bonding, unlike other forms of atomic bonding, involves delocalized elections. The negatively charged electrons form a "sea" around metal cations. Electrons within the valence shells of metals are only held loosely within their molecular orbits- the metals are held together due to the strong attraction between these delocalized electrons and positive nuclei.

The electrons are typically described as mobile, free, and delocalized. These traits are responsible for several metallic properties such as:

Why is meiosis important in maintaining genetic diversity?

Question 6 options:

A Meiosis creates diversity by cutting each chromosome exactly in half.


B The two different chromosomes of the organism producing the sex cell (egg or sperm) are mixed up during crossover, creating a new combination of alleles.


C It creates sex cells (eggs or sperm) that have exactly the same alleles (version of a gene) as the parents.


D The chromosomes in meiosis are copied so they are exactly the same as the organism producing the gamete, except they have just one copy.

Answers

Answer:

We now know that meiosis is the process of chromosomal reduction which allows the production of haploid germ cells necessary for sexual reproduction. Meiosis is furthermore important for its role in enabling genetic diversity and facilitating the repair of genetic defects through recombination.

Explanation:

Brainliest please?

Meiosis is a specialized form of a cell division in which number of chromosomes is reduced to half. The reduction in chromosome number is achieved by one round of DNA replication and two rounds of chromosome segregation.    

Meiosis produces genetic variation by the process of recombination.Recombination occurs when two molecules of DNA exchange pieces of their genetic material. The process of recombination occurs during the prophase stage of meiosis I. In meiosis, crossing over occurs between the non-sister chromatids in a homologous pair (one from each parent) of chromosomes.

The correct answer is option B. The two different chromosomes of the organism producing the sex cell (egg or sperm) are mixed up during crossover, creating a new combination of alleles.

Other options-

A. Meiosis creates diversity by cutting each chromosome exactly in half - incorrect .In meiosis the chromosome number is reduced to half.

C. It creates sex cells (egg or sperm) that have exactly the same alleles (version of a gene) as the parents-incorrect. The sex cells produced are not genetically identical to the parent cell.

D. The chromosome in meiosis are copied so they are exactly the same as the organism producing the gamete, except they have just one copy-incorrect. In meiosis the chromosomes are not exactly copied.
